  2. Description of the Related Art Some conventional gaming machines use a projector (projection device) instead of a liquid crystal display device that displays a video for a game or the like (see Patent Documents 1 and 2). In such a gaming machine, an image is projected from a projector onto a projection surface such as a screen.

JP-A-6-35066 JP 2009-240559 A

  However, in the above-mentioned conventional gaming machine, for example, heat tends to accumulate inside the projector main body as the operation time becomes longer, so that an optical component or a substrate provided inside the projector main body causes a defect due to heat, and a plastic lens is generated. In some cases, the image may be blurred or image noise may occur due to thermal deformation. Due to such a malfunction of the projection device, there is a possibility that an image projected according to the game may be uncomfortable.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a gaming machine capable of appropriately avoiding a malfunction of a projection device according to a situation and eliminating discomfort of an image. .

  In order to achieve the above object, the present invention provides the following gaming machines.

A gaming machine according to one aspect of the present invention,
A gaming machine (for example, gaming machine 1 or the like) provided with a projection device (for example, projector device B2 or the like) capable of projecting an image,
The projection device,
A first ventilation fan (for example, an exhaust fan 245 (FAN3) or the like) for performing ventilation;
A second ventilation fan (for example, an intake fan 244A (FAN1) or the like) that performs ventilation unlike the first ventilation fan;
Temperature detecting means (for example, an intake air temperature sensor B26a) for detecting the temperature of a predetermined location;
First rotation speed detecting means (for example, a pulse sensor B27c) for detecting the rotation speed of the first ventilation fan;
A second rotation speed detecting means (for example, a pulse sensor B27a) for detecting the rotation speed of the second ventilation fan;
Operation stop means (for example, a control LSI 230 of the projector control board B23) for stopping the operation during operation;
The operation stopping means,
If the temperature detected by the temperature detecting means is equal to or lower than the first temperature and the rotation speed detected by the first rotation speed detecting means is lower than the first rotation speed, the operation during operation is stopped. And when the temperature detected by the temperature detection unit is higher than the first temperature, the rotation speed detected by the first rotation speed detection unit is less than a second rotation speed higher than the first rotation speed. If it becomes, stop the operation in operation,
When the temperature detected by the temperature detecting means is equal to or lower than the first temperature, and when the rotational speed detected by the second rotational speed detecting means is lower than the second rotational speed, the operation during operation is performed. Is stopped, and when the temperature detected by the temperature detecting means is higher than the first temperature, the third rotational speed detected by the second rotational speed detecting means is higher than the second rotational speed. When the value is less than the predetermined value, the operation in operation is stopped.

  According to such a configuration, for example, as the operation time becomes longer, heat accumulates in the projection device, so that the operation is performed according to the detected temperature and the rotation speeds of the first ventilation fan and the second ventilation fan. Since the middle operation is stopped, the operation failure due to the heat accumulation of the projection device can be appropriately avoided according to the temperature and the number of rotations of the fan, and the discomfort of the image over a long time can be eliminated.

  According to the present invention, it is possible to provide a gaming machine capable of appropriately avoiding a malfunction of the projection device according to a situation and eliminating discomfort of an image.

That is, the side walls B13, B13 are formed so that the distance along the left-right direction between the tips of the second protrusions B131b is greater than the distance along the left-right direction between the tips of the first protrusions B131a. . Thereby, the projector cover B1 can cover most of the internal space in the cabinet G.

  In addition, a screw hole B131C penetrating in the up-down direction is formed at the tip of the second protrusion B131b. When fixing the projector cover B1 to the right side plate C2 and the left side plate C3 (see FIG. 5), screws are screwed into each of the right side plate C2 and the left side plate C3 via the screw holes B131C. Further, since the protruding portions B131 protrude from the lower ends of the side walls B13, B13 in the horizontal direction, the protruding portions B131 and the side walls B13 are provided on both side ends of the projector cover B1, and the recess B132 is formed from the front end thereof. Are formed continuously toward the rear.

  As shown in FIG. 9, when the display unit A is mounted on the cabinet G, a space BS is defined by the recess B132 and the cabinet G. The shape of the upper wall B12 and the side wall B13 of the projector cover B1 is such that the distance between the lower end of each side wall B13 and the tip of the second protrusion B131b protruding from the lower end is the second protrusion. The front part of B131b is configured to be larger than the rear part (see FIG. 8). As a result, the front space of the space BS becomes larger than the rear space. Further, when the display unit A is mounted on the cabinet G, at least a part of the opening G41 formed in the upper surface wall G4 of the cabinet G and the space in front of the space BS overlap when viewed from above. This space BS is used as a work space for installing and fixing the gaming machine 1 on the island facilities.

(Display unit A: Irradiation unit B: Perforated plate B15)
As shown in FIG. 10, a perforated plate B15 having a plurality of holes B151 is provided on the lower surface side of the projector cover B1. The perforated plate B15 is a punching metal in which a plurality of holes are formed by punching a plate made of a metal (for example, stainless steel, iron, steel, aluminum, or the like). The plurality of holes B151 are formed substantially uniformly dispersed over the entire surface of the perforated plate B15. The perforated plate B15 allows air to flow through the entire surface of the perforated plate B15, and allows air to flow from the lower side to the upper side or from the upper side to the lower side of the projector device B2. The size and number of the holes B151 are set so that the inside of the projector cover B1 cannot be seen from outside. The hole B151 is formed in a shape such as a circle, a square, or a hexagon, and has a hole diameter of about 3 to 5 mm.

  The perforated plate B15 is formed so as to cover the first protrusion B131a and the second protrusion B131b of the projector cover B1 from a lower position. The perforated plate B15 has an upper portion B15a on the front side, an inclined portion B15b on the middle portion, and a lower portion B15c on the rear side. The upper part B15a is arranged horizontally. The inclined portion B15b is formed to bend obliquely downward and backward from the rear side of the upper portion B15a. The lower part B15c is formed so as to bend in the horizontal direction from the rear side of the inclined part B15b.

  The upper part B15a of the perforated plate B15 is attached to the side walls B13, B13 of the projector cover B1. Thereby, the perforated plate B15 is arranged so as to cover the front part of the projector cover B1 from below with the upper part B15a, and to cover from the lower part with the inclined part B15b and the lower part B15c from the middle part to the rear part of the projector cover B1. I have. Further, the inclined portion B15b is disposed so as to surround the inclined surface B2a1 on the lower surface B2a of the projector device B2 when viewed from above. Then, as shown in FIG. 7, the inclination angle of the inclined portion B15b (the inclination angle with respect to the horizontal plane) is substantially the same as the inclination angle of the inclined surface B2a1. Below the perforated plate B15, a front screen mechanism E1 of the screen device C is disposed.

  The front screen mechanism E1 has a front standby position arranged on the upper side in a standby posture for inhibiting the appearance of an image by irradiation light and a front exposure position arranged on the lower side in an exposure posture for permitting the appearance of an image by irradiation light. The front screen mechanism E1 in the standby posture has an inclined posture substantially parallel to and close to the inclined portion B15b of the perforated plate B15. On the other hand, when the front screen mechanism E1 is in the exposed position, a large space portion appears below the perforated plate B15, and air existing in this space portion reaches the perforated plate B15 without flow resistance, and a plurality of spaces are formed. By passing through the hole B151, it is possible to facilitate the inflow of air into the screen device C and enhance the cooling effect.

  In addition, the perforated plate B15 is provided so as to cover the lower surface of the projector cover B1, so that, for example, as shown in FIG. The perforated plate B15 prevents the inside of the irradiation unit B from being viewed even if the irradiation unit B is present on the horizontal line of the part and looks up at the irradiation unit B from this line of sight.

(Display unit A: Screen device C)
As shown in FIG. 12, the irradiation unit B configured as described above is connected to the upper surface of the screen device C by screwing. For example, as described above, a screw is screwed into the upper surface of each of the right side plate C2 and the left side plate C3 of the screen device C via the screw hole B131C formed in the protruding portion B131 of the projector cover B1. Thereby, the display unit A can unite the irradiation unit B and the screen device C and integrally handle them.

(Display unit A: Screen device C: Screen mechanism)
Inside the screen housing C10, a plurality of screen mechanisms for displaying an image by irradiating the irradiation light from the irradiation unit B are provided so that the irradiation target can be switched. Specifically, as shown in FIG. 13, as the plurality of screen mechanisms, a fixed screen mechanism D, a front screen mechanism E1, and a reel screen mechanism F1 are provided. The projection surfaces of the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1 have different shapes to diversify the image expression. The front screen mechanism E1 and the reel screen mechanism F1 are movable screens whose positions are relatively displaced with respect to the projector device B2 and the mirror mechanism B3, respectively. (See FIG. 20). The front screen mechanism E1 is larger and heavier than the front screen mechanism E1 and the reel screen mechanism F1. Therefore, driving the front screen mechanism E1 requires a larger driving force than driving the reel screen mechanism F1.

(Display unit A: Screen device C: Screen housing C10)
As described above, the screen device C has the box-shaped screen housing C10. As shown in FIG. 13, the screen casing C10 includes a bottom plate C1 disposed horizontally, a right plate C2 erected on the right end of the bottom plate C1, and a left plate C3 erected on the left end of the bottom plate C1. And a back plate C4 erected at the rear end of the bottom plate C1. Accordingly, the right side plate C2, the left side plate C3, and the back plate C4 are connected to the bottom plate C1 by screw fastening, so that the front side where the player is located and the top side where the irradiation unit B is located are open. Box-shaped screen housing C10 is formed.

  Each of the bottom plate C1, the right plate C2, the left plate C3, and the back plate C4 is separately molded into a predetermined shape, and a predetermined functional component such as the fixed screen mechanism D can be positioned and arranged. Accordingly, even when the entire screen unit C cannot be shared, the unit can be shared by the plate members of the bottom plate C1, the right plate C2, the left plate C3, and the back plate C4. In addition, since it is possible to partially replace each plate member, it is possible to easily change specifications for each model of the gaming machine 1.

(Display unit A: Screen device C: Screen housing C10: Bottom plate C1)
The bottom plate C1 of the screen housing C10 is formed in a rectangular flat plate shape when viewed from above. The upper surface of the bottom plate C1 has a central placement part C11 arranged in the center, and a right placement part C12 and a left placement part C13 arranged in the left-right direction about the center placement part C11. . These mounting portions C11, C12, C13 are formed in a concave shape. The center mounting portion C11 mounts the fixed screen mechanism D so as to be positioned by fitting the lower end of the fixed screen mechanism D. The right mounting portion C12 mounts the right movable body base C5 in a positionable manner by fitting the lower end portion of the right movable body base C5. The left mounting portion C13 mounts the left movable base C6 in a positionable manner by fitting the lower end of the left movable base C6. The right and left movable bases C5 and C6 each have a three-dimensional pattern formed on the inner side in the left-right direction by unevenness. That is, the right movable base C5 and the left movable base C6 also function as decorative members. As described above, the fixed screen mechanism D, the right movable base C5, and the left movable base C6 can be positioned and arranged on the bottom plate C1.

  Further, the front portion C14 of the bottom plate C1 is bent downward, so that the front end portion is located below the lower surface of the bottom plate C1. A plurality of through holes C141 are formed in the front part C14. When the display unit A is mounted while being mounted on the intermediate support plate G1 (see FIG. 5) of the cabinet G, the front portion C14 comes into contact with the front surface of the intermediate support plate G1 so that the front unit C14 moves backward in the cabinet G. It is possible to perform positioning. The display unit A can be assembled and installed from the front side of the cabinet G by being screwed to the front surface of the cabinet G via the through hole C141 of the front part C14. It has become.

(Display unit A: Screen device C: Screen housing C10: Right side plate C2, Left side plate C3)
As shown in FIGS. 13 and 14, the right side plate C2 and the left side plate C3 of the screen housing C10 have operation openings C21 and C31. The operation openings C21 and C31 are formed as handles, and the display unit A can be carried by catching a hand on the operation openings C21 and C31. The operation openings C21 and C31 are arranged on the sides of the crank gears E21 and E21 of the front screen drive mechanism E2. The operation openings C21 and C31 are formed in a rectangular shape whose longitudinal direction is aligned in the horizontal direction. The opening areas of the operation openings C21 and C31 are set to such an extent that the crank gears E21 and E21 can be manually operated from outside.

  Thus, when the front screen mechanism E1 at the standby position is manually moved after the display unit A is installed in the cabinet G, first, the display unit A is taken out from the front side of the cabinet G in which the upper door mechanism UD is opened. . Specifically, an operator located on the front side of the cabinet G releases the screws of the display unit A to the cabinet G and removes the screws. Then, the user reaches into the cabinet G, holds the operation openings C21 and C31 of the display unit A with both hands, and takes out the display unit A out of the cabinet G. Thereafter, the user reaches the inside of the screen device C from one of the operation openings C21 of the detached display unit A, and rotates the crank gear E21 which is viewed in the horizontal direction from the operation opening C21. The mechanism E1 can be easily moved from the standby position. When the locked state is released by moving from the standby position, the front screen mechanism E1 can be quickly rotated to a desired position.

  In a state where the upper door mechanism UD is opened, a hand is reached from the front of the opening of the cabinet G into the space between the side wall G2 of the cabinet G and the right side plate C2 of the screen device C, and the operation opening C21 is opened. By operating the crank gear E21 from above, the crank gear E21 can be rotated. In this case, the locked state of the front screen mechanism E1 can be released without removing the display unit A out of the cabinet G.

  Further, a motor accommodating portion C22 is formed in the right side plate C2. The drive motor F24 of the reel screen drive mechanism F2 (see FIG. 20) is positioned by the motor housing portion C22. Further, a first support portion C23 for rotatably supporting a gear shaft E21a of a crank gear E21 in the front screen driving mechanism E2, and an intermediate gear E23 in the front screen driving mechanism E2 are respectively provided on the right side plate C2 and the left side plate C3. A second support portion C24 for rotatably supporting the shaft member E3 serving as the gear shaft of the first embodiment is formed. As described above, the front screen drive mechanism E2 and the reel screen drive mechanism F2 are positioned and arranged by the right side plate C2 and the left side plate C3. The right front screen drive mechanism E2B of the front screen drive mechanism E2 and the reel screen drive mechanism F2 are disposed between the right movable base C5 and the right plate C2 in the left-right direction. Further, the left front screen drive mechanism E2A is disposed between the left movable body base C6 and the left side plate C3 in the left-right direction.

(Display unit A: Screen device C: Screen housing C10: Back plate C4)
As shown in FIG. 15, the back plate C4 of the screen housing C10 is formed in a flat plate shape, and a concave portion CO for positioning and positioning the relay board CK is formed in a lower portion of the back surface thereof. The relay board CK includes various functional components (for example, the projector device B2, the front screen driving mechanism E2, the reel screen driving mechanism F2, and the like) of the display unit A, and various functional components other than the display unit A (such as a sub-control board SS described later). ) Is a relay board for relaying a wiring (not shown) with (a). The relay board CK includes a screen drive control board CS (see FIGS. 37 and 42) for exchanging signals and the like with the screen drive mechanisms E2 and F2.

  An operation opening C41 is formed in the back plate C4. The operation opening C41 is arranged on the lower right side, and faces the intermediate gear E23 of the front screen drive mechanism E2. The operation opening C41 is formed in a size that allows the intermediate gear E23 to be manually operated. Thus, when the front screen mechanism E1 at the standby position is manually moved after the display unit A is installed in the cabinet G, the display unit A is first removed from the cabinet G. Thereafter, the user reaches the inside of the screen device C through the operation opening C41 and rotates the intermediate gear E23 that is viewed in the horizontal direction from the operation opening C41, thereby easily moving the locked front screen mechanism E1 from the standby position. Can be moved.

  Further, the back plate C4 is disposed forward of the rear end of each of the right side plate C2 and the left side plate C3. Thus, when the display unit A is placed on the intermediate support plate G1 of the cabinet G, the space GS is formed by the rear wall G3 of the cabinet G and the right plate C2, the left plate C3, and the back plate C4 of the screen device C. Will be defined. That is, a gap is secured between the back wall G3 and the back plate C4. Thereby, even if the relay board CK is provided on the back surface of the back plate C4, it is possible to prevent the relay board CK from interfering with the rear wall G3 of the cabinet G due to the space GS.

  Further, a through hole G11 is formed in the intermediate support plate G1 at a position facing the space GS (see FIG. 5). The through-hole G11 is formed such that its opening surrounds the relay board CK in a top view. The relay board CK is arranged so that the connector CK1 to which wiring from a device (such as a sub-control board SS to be described later) housed in the lower space of the cabinet G is connected faces the through hole G11. . Thereby, the electrical connection between the relay board CK of the display unit A and the device accommodated in the lower space of the cabinet G is achieved by inserting the wiring from the device accommodated in the lower space into the through-hole G11. This can be performed by connecting to CK1.

  Since the relay board CK is arranged outside the screen device C in this way, the wiring work is facilitated, and it is not necessary to secure an installation space for the relay board CK in the screen device C, The degree of freedom of design in the screen device C is expanded. Further, heat generated from the relay board CK can be easily discharged to the outside through the ventilation holes G3a (see FIG. 2) formed in the rear wall G3 of the cabinet G.

  Further, the wiring connecting the relay board CK arranged in the upper space of the cabinet G and the device accommodated in the lower space of the cabinet G passes through the through hole G11 formed in the rear part of the intermediate support plate G1. Therefore, it is easy to arrange wiring behind various devices in the cabinet G. As a result, the degree of freedom of wiring can be increased.

  In addition, since the relay board CK is disposed at the rear part in the cabinet G, light hardly reaches the relay board CK, and as a result, it is difficult to connect wiring to the connector CK1 of the relay board CK. It is possible that Therefore, in order to facilitate the connection of the wiring from the device accommodated in the lower space of the cabinet G to the relay board CK, the connector CK1 of the relay board CK passes below the intermediate support plate G1 through the through hole G11. It may be constituted so that it may project. Further, the color of the connector CK1 may be a color having a high light reflectance (for example, white).

  As described above, the fixed screen mechanism D, the right movable body base C5, and the left movable body base C6 are positioned and arranged on the bottom plate C1. The drive motor F24 of the reel screen drive mechanism F2 is positioned and arranged on the right side plate C2, and the gear shaft E21a and the shaft member E3 of the front screen drive mechanism E2 are positioned and arranged on the right side plate C2 and the left side plate C3. The relay board CK is positioned and arranged with respect to the back plate C4. As described above, the fixed screen mechanism D, the screen drive mechanisms F2, E2, and the relay board CK are respectively positioned and arranged on one of the bottom plate C1, the side plates C2, C3, and the back plate C4, and They are positioned and arranged on different plates. Therefore, even when the entire display unit A cannot be shared among the models of the gaming machines 1, the common display unit A can be shared among the models on a board basis. As a result, it is possible to manufacture the display unit at lower cost than in the case where the display unit is manufactured for each model.

  Further, since the plates C1 to C4 of the screen housing C10 are connected by screw fastening, the connection between the plates C1 to C4 can be released by loosening the screws. That is, the screen housing C10 is assembled such that the respective plates C1 to C4 are exchangeable. This makes it possible to replace the functional components of the display unit on a board-by-board basis, thereby making it possible to change the specifications of the display unit A while reusing functional components that are not to be replaced by the display unit A. .

  In addition, as shown in FIGS. 13 and 20, the right movable base C5 is disposed on the left inner side of the right front screen drive mechanism E2B and the reel screen drive mechanism F2. Further, the left movable body base C6 is disposed on the right inside of the left front screen driving mechanism E2A. As a result, the right movable body base C5 and the left movable body base C6, which are the decorative members, make it difficult for the player to see these drive mechanisms E2 and F2. As a result, the aesthetic appearance of the gaming machine 1 can be improved. Further, since the bottom plate C1 is formed with a concave portion for arranging the right movable body base C5 and the left movable body base C6, these can be easily positioned and arranged on the bottom plate C1.

(Display unit A: Screen device C: Screen position relation)
As shown in FIG. 16, the fixed screen mechanism D is provided in a fixed state at a fixed exposure position existing in the irradiation direction of irradiation light. As shown in FIG. 17, the front screen mechanism E1 is provided rotatably between a front exposure position and a front standby position. The positional relationship between the fixed exposure position and the front exposure position is set such that the front exposure position is in the irradiation direction of the irradiation light and is located ahead of the fixed exposure position. Thus, when the front screen mechanism E1 moves to the front exposure position, the front screen mechanism E1 hides the fixed screen mechanism D from the front, so that the image by the irradiation light appears only on the front screen mechanism E1. Making it possible. When the front screen mechanism E1 moves to the front standby position, the fixed screen mechanism D is exposed, so that an image by the irradiation light can appear on the fixed screen mechanism D. That is, when the front screen mechanism E1 is arranged at the front exposure position, the front screen mechanism E1 becomes a projection target of the projector device B2. On the other hand, when the front screen mechanism E1 is located at the front standby position, the fixed screen mechanism D becomes a projection target of the projector device B2.

  As shown in FIG. 18, the reel screen mechanism F1 is provided rotatably between a reel exposure position and a reel standby position. The positional relationship between the reel exposure position and the fixed exposure position is set such that the reel exposure position is in the irradiation direction of the irradiation light and is located ahead of the fixed exposure position. Thereby, when the reel screen mechanism F1 moves to the reel exposure position, the image by the irradiation light appears only on the reel screen mechanism F1 by setting the reel screen mechanism F1 to cover the fixed screen mechanism D from the front. Making it possible. When the reel screen mechanism F1 moves to the reel standby position, by exposing the fixed screen mechanism D, it is possible to make the image by the irradiation light appear on the fixed screen mechanism D. That is, when the reel screen mechanism F1 is disposed at the reel exposure position, the reel screen mechanism F1 becomes a projection target of the projector device B2. On the other hand, when the reel screen mechanism F1 is arranged at the front standby position, the fixed screen mechanism D becomes a projection target of the projector device B2.

(Display unit A: Screen device C: Fixed screen mechanism D)
As shown in FIGS. 13 and 14, the fixed screen mechanism D is fixed on the bottom plate C1 of the screen housing C10 by screwing. The fixed screen mechanism D has a front reflector D1, a right reflector D2, a left reflector D3, and a lower reflector D4. The reflecting surfaces of these reflecting portions D1 to D4 are projection surfaces on which the irradiation light from the irradiation unit B is projected, and are set at different angles with respect to the optical axis of the irradiation light from the irradiation unit B.

  Note that the fixed screen mechanism D may have, for example, two, three, or five reflecting portions as long as it has a reflecting surface at a plurality of different angles with respect to the optical axis of the irradiation light, Alternatively, a reflecting portion of a curved or arc-shaped reflecting surface having a continuously changing angle with respect to the optical axis and having a center of curvature located on the front side may be provided.

  The front reflection part D1 has a reflection surface facing the player on the front side, and reflects most of the reflected light from the irradiation unit B disposed in the upper front part of the fixed screen mechanism D forward. It is set as follows. The right-side reflection unit D2 and the left-side reflection unit D3 are joined to the right and left sides of the front-side reflection unit D1, and are arranged symmetrically about the front-side reflection unit D1. The right-side reflection unit D2 and the left-side reflection unit D3 are arranged so that the width between the front end portions is larger than the width in the left-right direction of the front reflection unit D1. Thereby, the right-side reflection unit D2 and the left-side reflection unit D3 can easily reflect a part of the irradiation light while causing an image by the irradiation light to appear, because the reflection direction of the irradiation light toward the reflection surface is easily directed toward the front reflection unit D1. The light is reflected in the direction of the reflecting portion D1. Also, with respect to the lower surface reflection portion D4, a part of the irradiation light is directed toward the front reflection portion D1 while causing an image by the irradiation light to appear, because the direction of reflection of the irradiation light on the reflection surface is easily directed toward the front reflection portion D1. It is designed to reflect.

  In the fixed screen mechanism D, the brightness of the reflection surface is set lower than the brightness of each reflection surface of the front screen mechanism E1 and the reel screen mechanism F1. That is, in the fixed screen mechanism D, the amount of light reflected from the reflection surface of the irradiation light is smaller than the amount of light reflected from the reflection surfaces of the front screen mechanism E1 and the reel screen mechanism F1. Thereby, in the fixed screen mechanism D, the white blur due to the mixing of light due to the irregular reflection of the reflection units D1 to D4 is prevented. In the fixed screen mechanism D, the brightness of the other reflecting portions D2, D3, and D4 may be lower than the brightness of the front reflecting portion D1. In this case, it is possible to reduce the reflection of the irradiation light to the front reflection unit D1 in the other reflection units D2, D3, and D4, so that it is possible to reduce the white blur while making the image appear strongly in the front reflection unit D1.

  As the lightness, Brightness in the L * a * b * color system (L * a * b * color space) or the L * u * v * color system (L * u * v * color space) is adopted. However, any other color can be defined as long as other colors can be represented by relative values based on white.

  The brightness of the reflection surface of the fixed screen mechanism D and the brightness of the reflection surfaces of the front screen mechanism E1 and the reel screen mechanism F1 are the same as the brightness of the reflection surface of the fixed screen mechanism D and the reflection of the front screen mechanism E1 and the reel screen mechanism F1. There is no particular limitation as long as the brightness is lower than the surface brightness. For example, the brightness of the reflection surface of the fixed screen mechanism D may be set to a value about 5 to 25% (or 10 to 20%) lower than the brightness of the reflection surfaces of the front screen mechanism E1 and the reel screen mechanism F1.

  In order to make the lightness of the reflection surface of the fixed screen mechanism D lower than the lightness of the reflection surfaces of the front screen mechanism E1 and the reel screen mechanism F1, the color of the paint applied to the base material of the fixed screen mechanism D is changed to the front screen. What is necessary is just to make black the color of the paint applied to the base material of the mechanism E1 and the reel screen mechanism F1. For example, a white paint is used as the paint applied to the base material of the front screen mechanism E1 and the reel screen mechanism F1, and the paint applied to the base material of the fixed screen mechanism D is the paint of the front screen mechanism E1 and the reel screen mechanism F1. What added a black pigment to the paint applied to a substrate should just be used.

  In such a paint, the brightness of the reflection surface of the screen mechanism can be changed by changing the ratio between the white pigment (for example, titanium oxide) and the black pigment (for example, carbon black). For example, the paint applied to the base material of the front screen mechanism E1 and the reel screen mechanism F1 includes only the white pigment among the white pigment and the black pigment, and the paint applied to the base material of the fixed screen mechanism D includes: Both a white pigment and a black pigment may be included. Further, the ratio of the black pigment to the white pigment is higher in the paint applied to the fixed screen mechanism D than the paint applied to the base materials of the front screen mechanism E1 and the reel screen mechanism F1 (for example, 5 to 25% (or (About 10 to 20%)). In addition, as a coating material applied to the base material of these screen mechanisms, a conventionally known coating material for a screen can be appropriately used, and can be adjusted according to a screen type (for example, a diffusion type or a reflection type). .

  It is to be noted that the black pigment is not contained in the paint applied to the base material of the fixed screen mechanism D, but the black pigment is dispersed in the resin used as the material of the base material before the base material of the fixed screen mechanism D is formed. By doing so, the base material itself may be colored and the brightness of the base material itself may be reduced.

  Further, from the viewpoint of preventing diffused reflection of light, the members constituting the screen housing C10, such as the surrounding walls (the bottom plate C1, the right side plate C2, the left side plate C3, and the back plate C4), and the inside of the screen housing C10. It is desirable to lower the brightness of other members (members other than the screen) arranged in the. It is desirable that the brightness of those members is lower than the brightness of the reflection surface of the fixed screen mechanism D. For example, as for the surrounding wall, it is not necessary to consider that an image is projected as a screen, so if the brightness is low, Lower is more desirable. That is, the color of the surrounding wall is preferably as close to black as possible.

(Display unit A: Screen device C: Front screen mechanism E1)
As shown in FIG. 19, the front screen mechanism E1 includes a rectangular front screen member E11 having a projection surface E11a on the entire surface and a front screen support base E12 having a pattern such as a first pattern surface E12a on both surfaces. Have. The front screen member E11 is formed by applying a screen paint to a thin flat panel. Thereby, the front screen member E11 has a flat projection surface E11a.

  On the other hand, the front screen support E12 has a holding recess E121 that holds the front screen member E11. The holding recess E121 has an opening shape similar to the projection screen E11a of the front screen member E11 in a slightly enlarged state, and accommodates the entire front screen member E11. Further, the holding concave portion E121 is set to have two depths, a deep portion and a shallow portion. The shallow portion is realized by a step portion E121a formed on the peripheral portion of the front screen support base E12 and a step portion E121b formed linearly across both ends in the short direction passing through the center portion.

  As a result, the front screen member E11 housed in the holding recess E121 abuts and is supported by the step E121a of the peripheral portion and the linear step E121b passing through the center, and is separated from the remaining deep portion. Have been in a state. As a result, the deformation of the front screen support E12 in the deep portion prevents the front screen member E11 from deforming and causing distortion on the projection surface E11a.

  In addition, the front screen support base E12 has a first pattern surface E12a in a partial area around the projection surface E11a. The first pattern surface E12a is made visible to a player in front when the front screen mechanism E1 is positioned at the front exposure position. Further, the front screen support base E12 has a second pattern surface E12b on the entire surface opposite to the first pattern surface E12a. The second pattern surface E12b is made visible to a player in front when the front screen mechanism E1 is located at the front standby position. On the first pattern surface E12a and the second pattern surface E12b, for example, a pattern related to the effect of a game is formed three-dimensionally by unevenness.

  The front screen member E11 and the front screen support base E12 configured as described above are separately formed and then integrated by bonding with an adhesive. As a result, even if sink marks may occur due to molding shrinkage or the like when forming a pattern or the like on the front screen support E12, the sink marks are mechanically separated from the front screen member E11. Therefore, it is possible to prevent distortion due to sinking of the projection surface E11a of the front screen member E11.

  The method of fixing the front screen member E11 and the front screen support base E12 is not limited to bonding with an adhesive, but may be any method such as screw fastening.

  The flat panel constituting the front screen member E11 and the front screen support base E12 are each manufactured by injection molding. As a material of the flat panel constituting the front screen member E11 and the front screen support base E12, a thermoplastic resin (for example, an ABS resin or the like) capable of generating sink marks when injection molding is performed may be appropriately employed. it can.

(Display unit A: Screen device C: Front screen drive mechanism E2)
The front screen mechanism E1 is rotatable by the driving force of the front screen driving mechanism E2. As shown in FIGS. 13 and 14, the front screen driving mechanism E2 includes a left front screen driving mechanism E2A connected to a lower surface of a left end of the front screen mechanism E1, and a right screen connected to a lower surface of a right end of the front screen mechanism E1. And a front screen drive mechanism E2B.

  As shown in FIG. 17, the front screen mechanism E1 is configured to be inclined upward from the rear end toward the front end when arranged at the front standby position (in a standby posture). ing. The inclination of the front screen mechanism E1 is substantially parallel to the inclined portion B15b of the perforated plate B15 and the inclined surface B2a1 of the lower surface B2a of the projector B2.

  As described above, when the front screen mechanism E1 is disposed at the front standby position, the posture of the front screen mechanism E1 is inclined upward from the rear end toward the front end, so that the front screen mechanism E1 is parallel to the horizontal plane. As compared with the case of the posture, the irradiation light irradiated by the irradiation unit B can be suppressed from being hindered by the front screen mechanism E1. Thus, the vertical position of the front screen mechanism E1 when located at the front standby position can be made closer to the fixed screen mechanism D. As a result, even in the limited space of the display unit A, the size of the front screen mechanism E1 can be increased. In addition, as described above, since the lower surface B2a of the projector device B2 has the inclined surface B2a1, the vertical position of the front screen mechanism E1 when disposed at the front standby position is set with respect to the projector device B2. Can be approached. As a result, the size of the front screen mechanism E1 can be further increased.

  As shown in FIG. 14, the right front screen drive mechanism E2B has a crank member E22, a crank gear E21, an intermediate gear E23, a motor shaft gear E24, and a drive motor E25. A position where the upper end (one end) of the crank member E22 in the right front screen drive mechanism E2B is located on the rear surface of the right end of the front screen mechanism E1 when the front end is located at the front exposure position (in the exposure posture). It is connected to.

  At an intermediate position, the crank member E22 is rotatably supported by a right movable base C5 (see FIG. 13). This allows the crank member E22 to rotate at the upper end and the lower end (the other end) about the intermediate position as the center of rotation. Note that this intermediate position coincides with the rotation center axis of the front screen mechanism E1.

  As described above, the rotation center axis of the front screen mechanism E1 is disposed above the center position of the front screen mechanism E1 disposed at the front exposure position. Further, the crank member E22 has its upper end (one end) connected to a position on the rear surface of the right end portion of the front screen mechanism E1 to be an upper position when the crank member E22 is disposed at the front exposure position (in the exposure posture). . With the above configuration, the operating range between the front standby position and the front exposure position in the front screen mechanism E1 can be reduced, so that the size of the front screen mechanism E1 can be increased.

  A slide groove (not shown) is formed in a lower region of the crank member E22. The slide groove is formed to have a U-shape in side view. A slide member E26 (see FIG. 14) is movably engaged with the slide groove. That is, the slide member E26 is always in contact with the slide groove. The slide member E26 is rotatably supported at an eccentric position of the crank gear E21. As shown in FIG. 13, the gear shaft E21a of the crank gear E21 is rotatably supported by the right movable base C5 and the first support portion C23 of the right plate C2. When the front screen mechanism E1 is in the standby posture or the exposure posture, the line connecting the gear shaft E21a and the eccentric position is the center point between the intermediate position of the crank member E22 and the slide member E26. Are set so as to have a relationship orthogonal to the line segment connecting.

  Accordingly, when the front screen mechanism E1 is in the standby posture or the exposure posture, even if a force acts in a direction for rotating the lower region of the crank member E22, the gear shaft E21a is applied in a direction in which all components of the force are applied. Exists and acts as a fixed end, so that the slide member E26 does not move. As a result, a truss structure is formed by a three-joint link having zero degrees of freedom with the intermediate position of the crank member E22 and the gear shaft E21a of the crank gear E21 as fixed ends and the slide member E26 as a free end. Is pressed by hand, the front screen mechanism E1 does not move because the crank member E22 and the crank gear E21 act as strong brakes.

  An intermediate gear E23 is meshed with the crank gear E21. The intermediate gear E23 is rotatably supported by the right movable base C5 and the second support portion C24 of the right side plate C2. A motor shaft gear E24 meshes with the intermediate gear E23. The drive shaft of the drive motor E25 is connected to the motor shaft gear E24. Thus, the right front screen drive mechanism E2B can transmit the rotational driving force of the drive motor E25 to the crank gear E21 via the motor shaft gear E24 and the intermediate gear E23.

  Here, all components of the rotational driving force applied to the crank gear E21 coincide with the tangential direction of the turning locus of the slide member E26. When the front screen mechanism E1 is in the standby posture or the exposed posture, a line connecting the gear shaft E21a and the eccentric position of the slide member E26 connects the intermediate position of the crank member E22 and the center point of the slide member E26. Since it is set so as to have a relationship orthogonal to the line segment, the tangential direction of the turning locus is parallel to the slide groove of the crank member E22. Thus, when the rotational driving force is applied to the crank gear E21 when the front screen mechanism E1 is in the standby posture or the exposed posture, the crank gear E21 starts to rotate easily.

  When a rotational driving force is applied to the crank gear E21, the slide member E26 provided at the eccentric position is movable along the slide groove, and thus the intermediate position of the crank member E22 and the gear shaft of the crank gear E21. A two-joint link having one degree of freedom is formed in which E21a and E21a are fixed ends and the slide member E26 is a free end movable along a slide groove. When the slide member E26 rotates, the slide member E26 slides along the slide groove, so that the crank member E22 rotates around the intermediate position as a fulcrum, thereby rotating the upper region of the crank member E22. Become. As a result, the front screen mechanism E1 moves between the front standby position and the front exposure position.

  In the present embodiment, the drive motor E25 is a stepping motor, and is electrically connected to the sub control board SS via the relay board CK and the sub relay board SN (see FIG. 34). Drive controlled. The drive motor E25 may be connected to the main control board MS via the relay board CK, and may be driven and controlled by the main control board MS.

  Further, the moving speed of the front screen mechanism E1 gradually accelerates from 0 in a stopped state in a standby posture or an exposure posture, reaches a maximum speed in an intermediate posture between the standby posture and the exposure posture, and then gradually decelerates. When the exposure posture or the standby posture is reached, the stop state becomes 0 again. Accordingly, the rotation can be started and stopped in a state where the angular acceleration of the crank gear E21 is small (moment of inertia), so that the torque required for the crank gear E21 can be reduced, and as a result, the driving mechanism ( It is possible to reduce failure and wear due to overload of the intermediate gear E23, the motor shaft gear E24, and the drive motor E25).

  The right front screen drive mechanism E2B configured as described above has the same configuration as the left front screen drive mechanism E2A, except for the motor shaft gear E24 and the drive motor E25. The left front screen drive mechanism E2A and the right front screen drive mechanism E2B are arranged symmetrically. The intermediate gear E23 of the left front screen drive mechanism E2A and the intermediate gear E23 of the right front screen drive mechanism E2B are connected via a shaft member E3 (see FIG. 13).

  In the above configuration, when the drive motor E25 is driven, the motor shaft gear E24 is rotated. With the rotation of the motor shaft gear E24, the intermediate gears E23, E23 and the shaft member E3 of the left front screen drive mechanism E2A and the right front screen drive mechanism E2B respectively rotate integrally. Then, in conjunction with the rotation of the intermediate gears E23, E23, the crank gears E21, E21 are rotated, so that the front screen mechanism E1 is rotated about the rotation center axis, and the front standby position is shifted to the front standby position. It will move between the exposure positions.

  As described above, by connecting the intermediate gears E23 and E23 of the left front screen drive mechanism E2A and the right front screen drive mechanism E2B with the shaft member E3, the rotational driving force of the drive motor E25 is applied to the two crank members E22. It is possible to transmit evenly. Therefore, compared to a case where the intermediate gears E23 and E23 are not connected by the shaft member E3, it is possible to prevent the drive load from being concentrated on one of the two crank members E22. Further, since the drive motor E25 is provided in the right front screen drive mechanism E2B disposed to the right of the fixed screen mechanism D, the arrangement of the fixed screen mechanism D is not hindered.

  In addition, the shaft member E3 is not used as a rotation axis of the front screen mechanism E1. For this reason, the degree of freedom in the arrangement of the shaft member E3 is increased, and it is possible to arrange the shaft member E3 so as not to hinder the arrangement of another accessory such as the fixed screen mechanism D. As a result, it is possible to increase the degree of freedom in arranging the additional object while maintaining the rotation range and the size of the front screen mechanism E1 at desired levels.

  Further, since the shaft member E3 is disposed behind the fixed screen mechanism D, light projected on the fixed screen mechanism D is not obstructed by the shaft member E3. In addition, since the rotation center axis of the front screen mechanism E1 is located forward of the rear end position of the fixed screen mechanism D, it is compared with the case where the rotation center axis is located rearward of the rear end position of the fixed screen mechanism D. Thus, the length between the front screen mechanism E1 and the rotation center axis (the length of the crank member E22) can be reduced. For this reason, even when the space in the cabinet G is limited and the display unit A cannot be enlarged, the size of the front screen mechanism E1 can be maintained at a desired size.

(Display unit A: Screen device C: Reel screen mechanism F1)
As shown in FIG. 18, the reel screen mechanism F1 is formed of a curved flat plate. The reel screen mechanism F1 has an arcuate shape in a side view that is curved into a shape approximating the rotating direction. The surface of the reel screen mechanism F1 has a pattern formed on a peripheral edge thereof, and an inner peripheral area of the peripheral edge is a projection surface F1a. The projection surface F1a is an arc surface that is convex toward the upstream side in the light irradiation direction from the projector device B2 when the reel screen mechanism F1 is disposed at the reel exposure position. Further, a pattern is formed on the rear surface of the reel screen mechanism F1, which is the rotation center side. When the reel screen mechanism F1 is located at the reel standby position, the pattern on the back surface is made visible to the player in front.

  The reel screen mechanism F1 is rotatable between a reel standby position and a reel exposure position by a driving force of a reel screen driving mechanism F2. Then, when the reel screen mechanism F1 is located at the reel exposure position, the projection surface F1a is capable of displaying an image by irradiation of irradiation light.

(Display unit A: Screen device C: Reel screen drive mechanism F2)
As shown in FIG. 20, the reel screen drive mechanism F2 has two arm members F21 (not shown on the right side), an arc gear F22, a motor shaft gear F23, and a drive motor F24. One end of each of the two arm members F21 is connected to the right end rear surface and the left end rear surface of the reel screen mechanism F1. A support shaft F21a (not shown on the left side) is formed on the outer surface of the other end of each of the two arm members F21 so as to project outward in the left-right direction. These support shafts F21a are rotatably supported by the right movable base C5 and the left movable base C6, respectively. Thus, the two arm members F21 can rotate about the support shaft F21a as a rotation center. Note that these support shafts F21a coincide with the rotation center axis of the reel screen mechanism F1.

  The arc-shaped gear F22 is fixed to a distal end of a support shaft F21a disposed on the right side. A motor shaft gear F23 meshes with the arc gear F22. The drive shaft of the drive motor F24 is connected to the motor shaft gear F23. In the present embodiment, the drive motor F24 is a stepping motor, and is electrically connected to the sub control board SS via the relay board CK and the sub relay board SN (see FIG. 34). Drive controlled. The drive motor F24 may be connected to the main control board MS via the relay board CK, and may be driven and controlled by the main control board MS.

  In the above configuration, when the drive motor F24 is driven under the control of the sub-control board SS, the motor shaft gear F23 rotates. With the rotation of the motor shaft gear F23, the arc gear F22 rotates. Then, in association with the rotation of the arc gear F22, the arm member F21 is rotated, whereby the reel screen mechanism F1 is rotated around the rotation center axis, and the reel standby position and the reel exposure position are switched. Will work between.

(Display unit A: Screen device C: Sensor mechanism)
As described above, the operation ranges of the front screen mechanism E1 and the reel screen mechanism F1 partially overlap each other (see FIGS. 17 and 18). The front screen mechanism E1 and the reel screen mechanism F1 are driven by different driving mechanisms E2 and F2, respectively. That is, the driving of each of the front screen mechanism E1 and the reel screen mechanism F1 is not linked (synchronized). Therefore, in order to prevent interference (contact) between the screen mechanisms E1 and F1, it is necessary to know the positions of the screen mechanisms E1 and F1. Therefore, in this embodiment, the sub-control board SS (see FIG. 34) determines the position of the front screen mechanism E1 based on the front standby position as the origin position and the number of steps of the drive motor E25 from the origin position. ing. Similarly, the position of the reel screen mechanism F1 is determined based on the reel standby position as the origin position and the number of steps of the drive motor F24 from the origin position.

  However, when the operation of the front screen mechanism E1 or the reel screen mechanism F1 is not performed normally or when the front screen mechanism E1 or the reel screen mechanism F1 is manually moved while the power is turned off, the sub control board SS Cannot grasp the exact positions of the front screen mechanism E1 and the reel screen mechanism F1. If the front screen mechanism E1 and the reel screen mechanism F1 are operated in such a situation, they may interfere with each other.

  Therefore, in the present embodiment, the screen device C includes a sensor mechanism (not shown) for detecting the positions of the front screen mechanism E1 and the reel screen mechanism F1. Then, the sub-control board SS performs a return operation of returning the screen mechanisms E1 and F1 to the origin positions (standby positions) based on the detection result from the sensor mechanism.

  For example, as described above, since the front standby position and the reel standby position are each disposed in an overlapping range in the operation range of the screen mechanisms E1 and F1, when the front screen mechanism E1 is disposed in the front exposure position, The reel screen mechanism F1 is not arranged at the reel exposure position. Therefore, when the sensor mechanism detects that the front screen is at the front exposure position, it indicates that the reel screen mechanism F1 is not at the reel exposure position.

(Screen surface processing)
Next, the surface processing of the screen will be described. A screen to be projected, such as a front reflection section D1, right reflection section D2, left reflection section D3, and bottom reflection section D4 of the fixed screen mechanism D, a projection plane E11a of the front screen member E11, and a projection plane F1a of the reel screen mechanism F1. Is subjected to a graining process to achieve an appropriate performance. The graining process is a process in which a grain (wrinkle pattern) is formed on the surface. The screen or the like to be projected is molded using a mold that has been subjected to grain processing, whereby a wrinkle pattern is formed on the surface of the screen or the like to be projected. With such a wrinkle pattern on the surface, reflection of the light source can be effectively prevented, and furthermore, excellent reflection of the projected image can be realized.

  The graining includes a pattern called “pear-skin”. In the present embodiment, for example, a pear-skin pattern having a mean depth of about 25 μm to 30 μm and a draft of 3% or more (pear-skin No. 5) Is preferred.

  In addition, as a surface treatment of a screen or the like, a two-layer coating is applied to realize an appropriate performance. The two-layer coating means that paints having different characteristics are respectively applied on top and bottom (two layers). For example, a high-brightness paint having high reflectivity (for example, 2P-600 silver which is “ultra-high-brightness silver” of a metallic paint) is used for the undercoat, and a matte paint (for example, “matte” is used for the overcoat). HG-650 white). Also, about 5% of a matting agent (silica) can be added to HG-650 white.

  In such a coating, the thickness of the overcoat is, for example, 22 to 23 μm, and the thickness of the undercoat is, for example, about 1 μm. With such a coating, the gloss at a gloss of 60 ° is 4 to 5.

  In addition, 2P-600 silver uses vapor-deposited aluminum as the aluminum pigment, and the weight concentration (PWC) of the aluminum pigment in the coating film is set to 20 to 30%, which is higher than that of general silver paint, so that higher gloss is obtained. Values (reflection performance). The composition of HG-650 white is such that the resin is 20 to 30%, the titanium oxide is 30 to 40%, the matting agent silica is 5 to 10%, the additive is 0.5 to 2%, and the solvent is 30 to 40%.

  In addition, as a top coating, HG-650 white is used as a matting agent with glass- or resin-based beads having various average particle diameters added in a predetermined ratio, or with silica in addition to the beads. It can also be used. In addition, HG-650F clear or a paint obtained by adding beads having various average particle diameters as a matting agent to a HG-650F clear by a predetermined ratio can be used. The film thickness can be variously adjusted, for example, to 16 to 23 μm. The composition of HG-650F clear is such that the resin is 20 to 30%, the matting agent silica is 2 to 5%, the additive is 0.5 to 2%, and the solvent is 60 to 70%.

  As another undercoat paint, HG-650 white or a paint obtained by adding glass-based or resin-based beads having various average particle diameters as a matting agent to HG-650 white at a predetermined ratio can be used. Also, the film thickness can be variously adjusted, for example, from 1 to 21 μm.

  As described above, by forming a screen or the like to be projected by graining or by applying a two-layer coating, it is possible to effectively prevent the reflection of the light source, and to further improve the reflection of the projected image. Can be realized. In addition, the above-described two-layer coating may be applied to the screen or the accessory which has been subjected to the graining. The material such as a screen to be projected is, for example, a black or white ABS resin or a transparent polycarbonate resin, but is not limited thereto.

(Display unit A: Irradiation unit B: Electrical and optical configuration of projector device B2)
As shown in FIG. 21, the projector device B2 includes a projector control board B23, an optical mechanism B24, and a relay board CK as electrical components. A sub-control board SS to be described later is connected to the projector device B2 via a relay board CK. Although not shown in FIG. 21, the relay board CK and the sub-control board SS are connected via a scaler board SK (see FIGS. 37 and 43) described later. The sub-control board SS controls the projector control board B23 in accordance with the production operation of the screen and the accessory, and projects the irradiation light on the screen and the accessory via the optical mechanism B24, as a visual effect. Display video. Further, in the assembling process of the display unit A and the like, the adjustment PC (personal computer) 1000 is connected to the projector control board B23 (see FIGS. 30 and 37) of the projector device B2. The adjustment PC 1000 is used to adjust the position of the irradiation light projected by the projector device B2 and to perform initial focus setting (details will be described later). In the present embodiment, the adjustment PC 1000 is adopted as an adjustment device of the projector device B2. However, as the adjustment device of the projector device B2, a tablet PC or a so-called smartphone on which an adjustment program (application software) is installed is used. Or a dedicated terminal device.

  The projector control board B23 includes a control LSI 230, an EEPROM (registered trademark) 231, a DLP (registered trademark) control circuit 232, and an LED driver 233. As shown in FIG. 33, the optical mechanism B24 includes LED light sources 240R, 240G that emit light of each color of R (red), G (green), and B (blue) as components disposed around the lens unit B21. 240B, DMD 241, and a focus mechanism 242 for performing focus adjustment on the projection lens 210 of the lens unit B21.

  The control LSI 230 controls the DLP control circuit 232 to project the irradiation light based on a command from the sub-control board SS. The control LSI 230 controls the focus mechanism 242 to move the projection lens 210 in the optical axis direction based on a command from the sub-control board SS, thereby performing focus adjustment when projecting irradiation light. The EEPROM 231 stores data relating to the setting and adjustment of the projector B2 by the control LSI 230. Although not shown, the control LSI 230 includes a ROM in which a control program and the like are stored, and a DRAM used for a work area related to setting and adjustment of the projector B2.

  The DLP system of the projector B2 mainly includes a DLP control circuit 232, an LED driver 233, and the LED light sources 240R, 240G, 240B and DMD 241 of the optical mechanism B24.

  The DMD 241 is obtained by integrating a mirror corresponding to a pixel corresponding to a display resolution on a main surface of a semiconductor chip. The DMD 241 is configured such that each mirror is tilted by + 10 ° or −10 ° around an axis along a diagonal line with respect to the main surface due to an electrostatic field effect of a memory element immediately below each mirror. With such a configuration, each mirror of the DMD 241 is switched between an ON state (a state in which light is reflected in a predetermined direction) and an OFF state (a state in which light is reflected outside a predetermined direction). That is, when each mirror of the DMD 241 is in the ON state, the light incident from the LED light sources 240R, 240G, and 240B via a dichroic mirror or the like (not shown) is guided again to the lens unit B21 via the dichroic mirror or the like, while being OFF. In the state, the light incident from the LED light sources 240R, 240G, 240B via a dichroic mirror or the like is reflected toward a direction other than the lens unit B21.

  The DLP control circuit 232 controls an LED driver 233 that drives the LED light sources 240R, 240G, and 240B, and receives light of each color of RGB from the LED light sources 240R, 240G, and 240B in a time-division manner via a dichroic mirror (not shown) or the like. Incident on At this time, the DLP control circuit 232 determines at which timing the mirror corresponding to which pixel is to be turned on or off in accordance with the image to be projected, that is, which color light out of RGB light is transmitted at which timing. It is determined whether the light is reflected in a predetermined direction, and the ON / OFF state of each mirror of the DMD 241 is controlled.

  Under the control of the DLP control circuit 232, the light reflected in a predetermined direction by the DMD 241 proceeds to the lens unit B21, enters the mirror mechanism B3 by passing through the projection lens 210, and finally enters the mirror mechanism B3. By being reflected, it is guided to the projection target. As a result, the irradiation light is projected on the screen or the accessory serving as the projection target, and an image corresponding to the effect is formed.

  In the present embodiment, the projector device B2 is configured as a so-called DLP projector. In addition, the projector device B2 increases the projection distance to the projection target by turning back the irradiation light by the mirror mechanism B3, and shortens the projection distance of the irradiation light as much as possible by, for example, setting the contrast ratio to 1000: 1. ing. Accordingly, the display unit A including the projector device B2 is configured to be cheaper and smaller, and is easily mounted in a limited space in the cabinet G of the gaming machine 1.

(Display unit A: Irradiation unit B: Mechanical configuration of projector device B2)
As shown in FIGS. 22 and 23, the projector device B2 has a case B22, a lens unit cover B222, an undercover B223, an upper pedestal B220, and a lower pedestal B221 as exterior components. A lens unit cover B222 is attached to the front opening B22k of the case B22. The lower surface of the case B22 is disposed so as to cover the undercover B223. The under cover B223 is supported by the lower pedestal B221 via a stay B223a, and is also fixed to an appropriate lower surface of the case B22. The projector device B2 is attached to the lower surface of the upper wall B12 (see FIG. 8) of the projector cover B1 via the upper pedestal B220 and the lower pedestal B221. In the present embodiment, the upper pedestal B220 is fixed to the lower surface of the upper wall B12, and the lower pedestal B221 is attached to the upper end thereof so as to cover the upper opening of the case B22. The lower pedestal B221 is connected. The procedure for mounting and adjusting the projector device B2 will be described later.

  As shown in FIGS. 23, 24, and 33, the projector device B2 includes, as internal components, a lens unit B21, LED boards 240Ra, 240Ga, 240Ba, and a DMD 241 on which LED light sources 240R, 240G, 240B are mounted. DMD board 241a, a plurality of heat sinks 243R, 243G, 243B, 243D, intake fans 244A (FAN1), 244B (FAN2), exhaust fan 245 (FAN3), and projector control board B23. In the case B22, the lens unit B21 is housed while the projection lens 210 of the lens unit B21 is covered with the lens unit cover B222, and the LED boards 240Ra, 240Ga, 240Ba, the DMD board 241a, and the plurality of heat sinks 243R, 243G, 243B. , 243D, intake fans 244A, 244B, and exhaust fan 245 are accommodated. The projector control board B23 is fixed to the lower surface of the case B22. Although not particularly shown in FIG. 33 and the like, a temperature sensor B25 (see FIGS. 21 and 37) made of, for example, a thermistor is mounted on the LED boards 240Ra, 240Ga, 240Ba and the DMD board 241a. These temperature sensors B25 detect temperatures near the LED light sources 240R, 240G, 240B and near the lens unit B21, and output a temperature detection signal to the projector control board B23.

  The lens unit B21 includes an optical case B21a for accommodating a dichroic mirror and a reflector (not shown), a lens group 210A including the projection lens 210, a lens holder B21b provided at a front portion of the optical case B21a while holding the lens group 210A, and There is a focus mechanism 242 provided on the front right side of the optical case B21a so that a part of the lens holder B21b can be moved in the optical axis direction (front-back direction). The optical case B21a is provided with an opening that allows the LED light sources 240R, 240G, 240B and the DMD 241 to face from outside to inside. The rear part of the lens holder B21b is fixed to the front part of the optical case B21a, while the front part is relatively moved in the front-rear direction (optical axis direction) by the focus mechanism 242 with respect to the rear part. Holds a projection lens 210. Note that the lens unit B21 is provided with a so-called lens shift mechanism (not shown), and the horizontal and vertical positions (horizontal image position, vertical direction) of the projected image by using this lens shift mechanism are provided. (Image position) can be finely adjusted.

  The focus mechanism 242 focuses on the reflection surfaces of the reflection units D1 to D4 and the projection surfaces E11a and F1a displaced with respect to the projector device B2 while changing the focal length of the projection lens 210. The focus mechanism 242 is arranged along the optical axis direction of the projection lens 210 and a rack member 242A that can move integrally with the front part of the lens holder B21b that holds the projection lens 210, and is screwed with the rack member 242A. A lead screw 242B that can rotate while rotating, and a focus motor 242C that rotates the lead screw 242B. The focus motor 242C is connected to the control LSI 230 of the projector control board B23.

  For example, when the focus motor 242C rotates the lead screw 242B in a predetermined direction, the rack member 242A moves forward by a feed screw operation, and the projection lens 210 moves forward together with the rack member 242A. By making the focal length relatively long, the focus (focus position) can be adjusted to a distant place. On the other hand, when the focus motor 242C rotates the lead screw 242B in a direction opposite to the predetermined direction, the rack member 242A moves rearward by the feed screw operation, and the projection lens 210 is integrated with the rack member 242A and the front lens 242A also moves forward. As a result, the focal length is relatively shortened, so that a closer focus (focus position) is achieved.

  According to such a focus mechanism 242, the focal length can be dynamically changed in conjunction with the movement of the projection planes E11a and F1a. Also, for example, when the projection target is changed from the projection plane E11a to the projection plane F1a, or vice versa, the optical path length from the projection lens 210 to each projection target differs to some extent. The focal point (focus position) can be statically changed so as to have an appropriate focal length according to the length.

  The front portion of the lens holder B21b and the projection lens 210 are covered with a lens unit cover B222. The lens unit cover B222 is provided with a light transmitting surface B222a through which light emitted from the projection lens 210 is transmitted. Light emitted from the projection lens 210 is transmitted through the light transmitting surface B222a and proceeds to the mirror mechanism B3. .

  The LED board 240Ra is disposed in the case B22 so as to be adjacent to the rear right side of the optical case B21a, and the LED light source 240R faces the inside of the optical case B21a. The LED board 240Ga is disposed in the case B22 so as to be adjacent to the rear deep side of the optical case B21a, and the LED light source 240G faces the inside of the optical case B21a. The LED board 240Ba is disposed in the case B22 so as to be adjacent to the rear left side of the optical case B21a, and the LED light source 240B faces the inside of the optical case B21a. The DMD board 241a is arranged in the case B22 so as to be adjacent to the left side surface of the optical case B21a, and the DMD 241 faces the inside of the optical case B21a. Here, in the present embodiment, as the heat generation characteristics of the LED light sources 240R, 240G, 240B, and DMD 241, the LED light sources 240G and 240B tend to be relatively high, while the LED light sources 240R and DMD 241 are relatively high. It shows a low trend.

  As shown in FIG. 24A, a focus mechanism 242 is disposed on the right side of the lens holder B21b, and a projection lens 210 is disposed in front of the lens holder B21b. The front part of the lens holder B21b can be moved in the optical axis direction of the projection lens 210 by the focus mechanism 242. Although not described in detail, the focus mechanism 242 includes a stepping motor, a lead screw, a carriage, and the like, and is configured to be able to move the front part of the lens holder B21b in the optical axis direction.

  That is, the projection lens 210 can be moved by the focus mechanism 242 integrally with the front part of the lens holder B21b, and as shown in FIG. 24A, from the rear side to the front side along the optical axis direction. Or, it moves from the front side to the rear side.

  As shown in FIG. 24A, light from the LED light sources 240R, 240G, 240B reaches the DMD 241 via a collimator, a dichroic mirror and the like (not shown), is reflected by the DMD 241, and is then reflected by the dichroic mirror and the like. And finally exits through the projection lens 210.

  As described above, the projection lens 210 is configured to move in the optical axis direction. As a result, focus adjustment is performed, and a focused and clear image is projected on the screen or the accessory whose position has been changed by the movement.

  The projector device B2 is controlled by the sub-control board SS such that image data relating to an image such as a performance is transmitted from the sub-control board SS, and the image is projected on a screen or an accessory. On the other hand, the sub-control board SS controls the screen driving mechanisms E2 and F2 to move the screen mechanisms E1 and F1 according to the effect contents.

  Here, the sub-control board SS controls the projector device B2 in accordance with the movement of the screen mechanisms E1 and F1 by the effect, and the projection planes E11a and F1a of the moved screen mechanisms E1 and F1 and the projection plane of the fixed screen mechanism D. The focus is adjusted so that the image is clearly projected.

  The heat sink 243R is disposed on the right side inside the case B22, and partially contacts the rear surface of the LED board 240Ra. The heat sink 243G is arranged on the rear side in the case B22, and partially contacts the rear surface of the LED board 240Ga. The heat sink 243B is arranged at the center in the case B22, and partially contacts the rear surface of the LED board 240Ba. The heat sink 243D is arranged on the left side inside the case B22, and partially contacts the back surface of the DMD board 241a. Here, in the present embodiment, as the fin outer size of the heat sinks 243R, 243G, 243B, 243D, the heat sinks 243R and 243G are relatively large, while the heat sinks 243B and 243D are relatively small. These heat sinks 243R, 243G, 243B, and 243D dissipate the heat generated in each of the LED boards 240Ra, 240Ga, 240Ba and the DMD board 241a into the air, so that the temperature of the optical element or the board is changed until the optical characteristics are significantly changed. Heat is dissipated efficiently so as not to rise. The heat sinks 243R, 243G, 243B, and 243D, which are heat dissipating members, are made of an aluminum material having high heat conductivity in order to enhance the heat dissipating effect, and have a plurality of heat dissipating fins for increasing the contact area with air.

  The intake fan 244A is arranged so as to be close to the rear surface of the right front portion of the case B22, and is close to the heat sink 243R. The intake fan 244B is arranged so as to be close to the rear surface of the left part of the case B22, and is close to the heat sink 243D. The exhaust fan 245 is arranged close to the rear surface of the rear part of the case B22, and close to the heat sink 243G.

  Here, as shown in FIGS. 31 and 32, an intake port B22A is provided at a right front portion of the case B22 to which the intake fan 244A is close, and a heat sink 243R is close to the intake port B22A. An exhaust port B22E is provided at a right rear portion of the case B22. An intake port B22B is provided at a part of the left side of the case B22 to which the intake fan 244B is close, and another part of the left side of the case B22 is aligned with the intake port B22B. The air inlet B22C is provided so that the air reaches the three heat sinks 243G, 243B, and 243D through the empty space S. An exhaust port B22D is provided at a rear portion of the case B22 near the exhaust fan 245.

  That is, as shown in FIG. 33, in the case B22 of the projector device B2, after being forcibly sucked by the suction fan 244A from the suction port B22A, the air is exhausted from the discharge port B22E while removing heat from the heat sink 243R. An air flow path P1 is formed as a flow of air. Further, in the case B22, after the air is forcibly sucked from the air inlet B22B by the air suction fan 244B, the air is forcibly sucked from the heat sink 243D, the heat sink 243B, and the heat sink 243G by the air exhaust fan 45 from the air outlet B22D. An air flow path P2 is formed as a flow of air exhausted to the air. Further, in the case B22, after the air is sucked in from the air inlet B22C, the air flow path is forcibly exhausted by the exhaust fan 45 from the exhaust port B22D while mainly removing heat from the heat sink 243G and the heat sink 243B. P3 is formed.

  The projector control board B23 is attached to the lower surface of the case B22 while being covered by the under cover B223. On the projector control board B23, a control LSI 230, an EEPROM 231, a DLP control circuit 232, an LED driver 233, and the like are mounted. The projector control board B23 is electrically connected to the LED boards 240Ra, 240Ga, 240Ba and the DMD board 241a arranged in the case B22, and further to the focus mechanism 242.

(Display unit A: Irradiation unit B: Position / posture adjustment of projector device B2)

And a rear end portion 2202 extending to the rear end. The body 2200 and the rear end 2202 are provided with three connection holes 2200A for connecting the lower pedestal B221. These three connection holes 2200A are arranged so as not to be located on the same straight line in a plane (horizontal plane) along the main body 2200. Each of the left end 2201a and the right end 2201b is provided with a plurality of square holes 2201c for fixing to the lower surface of the upper wall B12 by screwing. In the present embodiment, three square holes 2201c are disposed at each of the left end 2201a and the right end 2201b, and are provided at equal intervals in the front-rear direction. The vertical and horizontal inner diameter dimensions of the square hole 2201c are larger than the screw shaft diameter of the mounting screw T (see FIG. 28) inserted and fastened thereto.

  The lower pedestal B221 is a sheet metal member substantially corresponding to the main body 2200 and the rear end 2202 of the upper pedestal B220. Three connection screw portions 2210 are integrally formed on the lower pedestal B221 so as to protrude upward corresponding to the three connection holes 2200A. These three connection screw portions 2210 are also arranged so as not to be located on the same straight line in a plane (horizontal plane) along the lower pedestal B221. The lower pedestal B221 inserts the tip of the connection screw portion 2210 into the connection hole 2200A while externally fitting the coil spring 2211 to each of the connection screw portions 2210, and sandwiches the coil spring 2211 between the main body portion 2200 and the rear end portion 2202. By connecting the nut 2213 from the upper surface side of the upper pedestal B220 to the tip of the connection screw portion 2210 via the washer 2212 while being in the slidable state, the upper pedestal B220 is suspended and connected to the lower surface of the upper pedestal B220. Further, as shown in FIG. 23, the lower pedestal B221 is provided with a plurality of screw holes 2214 for screwing the case B22 and a plurality of screw holes 2215 for screwing the stay B223a. The lower pedestal B221 is connected to the lower surface of the upper pedestal B220 while supporting the undercover B223 via the case B22 and the stay B223a.

  That is, as shown in FIG. 23 and FIGS. 25 to 27, the upper pedestal B220 and the lower pedestal B221 are connected to each other at three connection portions R1, R2, and R3 so that the distance between them can be adjusted. Each of the connection portions R1, R2, and R3 includes a connection hole 2200A of the upper pedestal B220, a connection screw portion 2210 of the lower pedestal B221, a coil spring 2211, a washer 2212, and a nut 2213.

  By using such an upper pedestal B220 and a lower pedestal B221, the projector apparatus B2 is attached to the upper wall B12 of the projector cover B1 so as to be capable of performing positioning adjustment and optical axis adjustment.

  FIG. 28 shows an attachment form of the upper pedestal B220 to the upper wall B12 of the projector cover B1. The lower view of FIG. 28 (a) is a view showing a state where the mounting screw T is inserted and fastened to the square hole 2201c of the upper pedestal B220, and the upper view of FIG. 28 (a) is a view of FIG. It is sectional drawing which follows the BB 'line | wire shown in a lower figure. FIG. 28 shows the periphery of the square hole 2201c formed in the left end 2201a of the upper pedestal B220, but the same applies to the periphery of the remaining square hole 2201c in the left end 2201a and the right end 2201b.

  As shown in FIG. 28 (a), a mounting screw T is inserted into the square hole 2201c from below, and the mounting screw T is disposed substantially at the center of the square hole 2201c. The mounting screw T is screwed to a nut N located on the upper surface side of the upper wall B12 via a washer W arranged along the upper surface of the upper wall B12 and the lower surface of the left end 2201a. Thus, the left end 2201a of the upper pedestal B220 is attached to the upper wall B12 of the projector cover B1 by screwing. The right end 2201b of the upper pedestal B220 is also attached to the upper wall B12 of the projector cover B1 with the same screws.

  Here, a hatched portion indicated by a symbol A in FIG. 28A is a gap formed between the screw shaft of the mounting screw T and the square hole 2201c. In FIG. 28A, the screw shaft of the mounting screw T is arranged and fixed substantially at the center of the square hole 2201c. At this time, the screw shaft of the mounting screw T can be moved within the range (adjustment range) of the hatched portion of the symbol A. That is, by finely adjusting the relative position of the mounting screw T with respect to the square hole 2201c within the opening range of the square hole 2201c, the left end 2201a of the upper pedestal B220 is positioned and adjusted with respect to the upper wall B12 of the projector cover B1. be able to. Similarly, the right end 2201b of the upper pedestal B220 can be positioned and adjusted with respect to the upper wall B12 of the projector cover B1.

  FIG. 28B shows a state in which the left end 2201a of the upper pedestal B220 is shifted in the direction of arrow E with respect to FIG. The upper diagram of FIG. 28B is a cross-sectional view along the line D-D ′ shown in the lower diagram of FIG. In the state shown in FIG. 28B, the screw axis of the mounting screw T is relatively deflected to the left within the opening range of the square hole 2201c, and is within the range of the hatched portion indicated by the reference symbol C (adjustment range). Can be moved.

  As described above, the upper pedestal B220 is attached to the upper wall B12 of the projector cover B1 while being positioned and adjusted within a predetermined adjustment range that is the opening range of the square hole 2201c. That is, in the projector device B2, the mounting position with respect to the upper wall B12 is adjusted in the left-right direction and the front-back direction by the plurality of square holes 2201c provided in the left end 2201a and the right end 2201b of the upper pedestal B220. Accordingly, the direction of the light emitted from the projector device B2 is easily adjusted so as to be perpendicular to the left-right direction and coincide with the front-back direction as the reference direction.

  FIG. 29 shows a connection structure of the lower pedestal B221 to the upper pedestal B220. FIG. 29 is a cross-sectional view showing a state where the lower pedestal B221 is connected to the upper pedestal B220 by the connection hole 2200A, the connection screw portion 2210, the coil spring 2211, the washer 2212, and the nut 2213 in the connection portion R2. Although FIG. 29 shows one connecting portion R2, the other connecting portions R1 and R3 are also the same.

  The connection screw portion 2210 of the lower pedestal B221 is inserted into the connection hole 2200A from the lower surface side of the main body 2200 of the upper pedestal B220, and is screwed to the nut 2213 via a washer 2212 disposed on the upper surface side of the main body 2200. You. A coil spring 2211 is externally fitted to the connection screw portion 2210, and the coil spring 2211 is held between the lower surface of the main body 2200 and the upper surface of the lower pedestal B221 at the periphery of the connection hole 2200A. By such a coil spring 2211, a portion near the connecting portion R <b> 2 between the upper pedestal B <b> 220 and the lower pedestal B <b> 221 is urged in a direction away from each other (vertical direction). Prevention of loosening at the joint portion is achieved.

  In such a connection portion R2, the distance between the upper pedestal B220 and the lower pedestal B221 is changed while being urged by the coil spring 2211 by appropriately turning the nut 2213 in the tightening direction or the loosening direction. Specifically, when the nut 2213 is turned in the tightening direction, the distance between the upper pedestal B220 and the lower pedestal B221 in the connection R2 is reduced. At this time, the upper pedestal B220 is fixed to an upper wall B12 not shown in FIG. Therefore, the portion near the connecting portion R2 of the lower pedestal B221 is displaced in a direction approaching the upper pedestal B220 by appropriately tightening the nut 2213, and the height position is adjusted to a higher position. On the other hand, when the nut 2213 is turned in the loosening direction, the distance between the upper pedestal B220 and the lower pedestal B221 in the connection R2 is increased. That is, the portion near the connecting portion R2 of the lower pedestal B221 is displaced away from the upper pedestal B220 by appropriately loosening the nut 2213, and the height position is adjusted to a lower position.

  In the other connecting portions R1 and R3 as well, the height of the lower pedestal B221 near the connecting portions R1 and R3 can be easily adjusted by appropriately adjusting the amount of tightening of the nut 2213 as described above. Specifically, the connecting portions R1, R2, and R3 form a triangular shape so that the connecting lines R1, R2, and R3 are not located on the same straight line in a plane (in a horizontal plane) along the upper pedestal B220 and the lower pedestal B221. Are arranged as follows. That is, since the lower pedestal B221 can finely adjust the height position by the tightening amount of the nut 2213 at each of the three connecting portions R1, R2, and R3, the posture of the lower pedestal B221 can be changed in the front-rear direction, It is possible to adjust the degree of tilt in the three-dimensional space in both the left-right direction and the up-down direction.

  Such a posture adjustment of the lower pedestal B221 is performed while irradiating a screen or the like with light from the projector device B2 supported by the lower pedestal B221. At this time, an image is projected on the screen or the like by the irradiation light, and the posture of the lower pedestal B221 is adjusted while checking the image. As a result, the direction of the optical axis of the light emitted from the projector device B2 is adjusted so that an image is projected on a surface such as a screen in an appropriate display mode. That is, the optical axis direction can be adjusted in advance by adjusting the posture of the lower pedestal B221 so that a so-called trapezoidal distortion or the like does not occur in the image display mode.

  As shown in FIG. 30, the adjustment in the optical axis direction and the like are performed using the adjustment PC 1000 connected to the projector device B2 via the sub-control board SS and the like. The projector device B2 attached to the upper wall portion B12 via the upper pedestal B220 and the lower pedestal B221 performs adjustment of the optical axis direction and checks the display image on a screen or the like at the time of inspection at a factory or the like. Various adjustments necessary for projecting and displaying an image are performed. The adjustment PC 1000 is temporarily connected to the projector control board B23 of the projector B2 during the adjustment work (see FIG. 37). When the adjustment PC 1000 is operated, optical parameters relating to the projection position of irradiation light, focus adjustment, and the like in the projector device B2 are changed by a predetermined command transmitted from the adjustment PC 1000. The projection position and the optical parameters appropriately adjusted in this manner include adjustment values data (horizontal position (horizontal image position) A to E adjustment values, horizontal position and vertical direction and focus position, vertical position (vertical direction Image positions) A to E adjustment values and focus positions A to E adjustment values are stored in the EEPROM 231 of the projector control board B23 (see FIG. 106). The adjustment value data of the horizontal direction, the vertical direction, and the focus position stored in the EEPROM 231 is not supplied to the projector device B2 for transportation after shipment from the factory, and the gaming machine 1 is installed in the game arcade. But it can be used as it is. Such horizontal position adjustment and vertical adjustment data are obtained to control the lens shift mechanism of the lens unit B21, and the focus position adjustment value data is obtained to control the focus mechanism 242. . Note that the horizontal position A to E adjustment value, the vertical position A to E adjustment value, the focus position A to E adjustment value, the horizontal position (horizontal image position) A to E offset, and the vertical position ( "A-E" of the vertical image position) A-E offset, focus position A-E offset, and focus drift correction value A-E are, for example, "A" is the projection surface of the fixed screen mechanism D, and "B" is the The projection planes E11a and “C” of the front screen member E11 correspond to the adjustment value data corresponding to the projection plane F1a of the reel screen mechanism F1, and “D” and “E” indicate future expandability (when the projection plane is (In case of increase).

  As is clear from the above description with reference to FIGS. 28 to 30, the projector device B <b> 2 is positioned mainly in the left-right direction and the front-back direction according to the mounting position on the upper wall B <b> 12 of the upper pedestal B <b> 220. The optical axis direction is adjusted according to the posture of the side pedestal B221 in the three-dimensional space.

  In this embodiment, the connecting portions for connecting the upper pedestal B220 and the lower pedestal B221 to each other are provided at three places. However, if at least three places satisfy the condition that they are not on the same straight line, four places are provided. The connecting portion may be provided as described above. In the present embodiment, the connection holes 2200A are provided in the upper pedestal B220 and the connection screw portions 2210 are provided in the lower pedestal B221. However, these connection holes and the connection screw portions may be provided upside down. The connecting screw portion is not limited to the one formed integrally with the pedestal as in the present embodiment, but may be any as long as it can be fixed to one pedestal. For example, the connection screw portion may be a bolt fixed through the lower pedestal.

(Display unit A: Irradiation unit B: Air intake and exhaust structure of projector device B2)
As shown in FIGS. 31 to 33, the case B22 of the projector device B2 is provided with three intake ports B22A, B22B, and B22C, and is provided with two exhaust ports B22D and B22E. Of the three intake ports B22A, B22B, and B22C, two intake ports B22A and B22B are provided with intake fans 244A and 244B, while one intake port B22C is not provided with an intake fan. Further, of the two exhaust ports B22D and B22E, one exhaust port B22D is provided with an exhaust fan 245, while the other exhaust port B22E is not provided with an exhaust fan.

  At the intake port B22A, air is forcibly taken into the case B22 by the intake fan 244A, and the flow of the air passes through the heat sink 243R as the air flow path P1, thereby removing heat from the heat sink 243R. Thereafter, the air flow path P1 flows linearly from the heat sink 243R to the exhaust port B22E, and is naturally discharged (exhausted) from the exhaust port B22E to the outside of the case B22.

  Also at the intake port B22B, air is forcibly taken into the case B22 by the intake fan 244B. This air flow passes through a plurality of heat sinks 243D, 243B, 243G while passing through a part of the empty space S as an air flow path P2, thereby removing heat from the plurality of heat sinks 243D, 243B, 243G. Thereafter, the air flow path P2 is drawn into the exhaust fan 245, flows so as to bend toward the exhaust port B22D, and is forcibly discharged (discharged heat) from the exhaust port B22D to the outside of the case B22.

  At the intake port B22C, air is semi-forcibly taken into the case B22 mainly by the retraction force of the exhaust fan 245. The flow of the air mainly passes through the heat sinks 243B and 243G while passing through a substantial part of the empty space S as the air flow path P3, thereby removing heat from the plurality of heat sinks 243B and 243G. Thereafter, the air flow path P3 is also drawn into the exhaust fan 245 so as to bend toward the exhaust port B22D, and is forcibly discharged from the exhaust port B22D to the outside of the case B22 while merging with the air flow path P2. (Exhausted heat). The intake fans 244A and 244B and the exhaust fan 245 function as a cooling device for the projector device B2.

  In the present embodiment, as described above, the LED light sources 240G and 240B exhibit relatively high heat generation characteristics, while the LED light sources 240R and DMD 241 exhibit relatively low heat generation characteristics. The LED substrates 240Ga and 240Ba on which the LED light sources 240G and 240B having high heat generation characteristics are mounted are in thermal contact with the heat sinks 243G and 243B through which the plurality of air flow paths P2 and P3 pass.

  Here, the plurality of air flow paths P2 and P3 join at a single exhaust port B22D while flowing from separate intake ports B22B and B22C, and flow out of the exhaust port B22D using the exhaust port B22D as a common vent. It has become. Thereby, the plurality of air flow paths P2 and P3 are forcibly discharged while being merged into a smooth flow, so that the plurality of heat sinks 243G and 243B can be efficiently taken out of heat and cooled. .

  Further, since the plurality of air flow paths P2 and P3 are efficiently and forcibly discharged by the exhaust fan 245, the heat pool caused by the plurality of optical elements such as the LED light sources 240G and 240B and the DMD 241 in the projector device B2 is effectively prevented. And overheating of optical components such as lenses can be prevented.

  Further, since three more heat sinks 243D, 243B, 243G are cooled by the two air flow paths P2, P3 communicating with one exhaust port B22D, they are provided corresponding to these heat sinks 243D, 243B, 243G. A plurality of optical elements such as the DMD 241 and the LED light sources 240B and 240G can be cooled more efficiently.

  In the present embodiment, the two air flow paths P2 and P3 merge at one exhaust port 245. However, for example, three or more air flow paths P1 are also merged at the exhaust port 245. May be collectively discharged from one exhaust port.

Further, a sub relay board SN is provided between the sub control board SS and the intermediate support plate G1. Above the hopper mechanism HP, there is provided a medal supply mechanism MH (corresponding to a supply port) for supplying metal medals from the outside, and medals are dropped from the medal supply mechanism MH to the hopper mechanism HP. Above the medal supply mechanism MH, a scaler substrate SK for connecting the projector device B2, the sub liquid crystal display device DD19, and the touch panel DD19T to the sub control substrate SS is provided.

  In the present embodiment, the sheet metal BK is not in contact with the sub-control board SS. The sheet metal BK may be directly attached to the bottom of the sub-control board SS. The thin sub-relay board SN detachably attached to the lower surface of the intermediate support plate G1 and the thin sub-control board SS detachably attached to the rear wall G3 of the cabinet G are viewed from the side. They are arranged in a state where the L-shape is upside down.

  According to the above configuration, since the sheet metal BK is provided between the sub-control board SS and the hopper mechanism HP, even if a medal is dropped on the hopper mechanism HP and jumps out toward the sub-control board SS, the sheet metal BK is used. The medal can be prevented from physically contacting the sub-control board SS. Further, since the sheet metal BK is provided between the sub-control board SS and the hopper mechanism HP, the influence of radiation (electromagnetic field) due to contact between metal medals in the hopper mechanism HP can be prevented by the sheet metal BK. Further, the sub-control board SS is provided at the back of the lower space of the cabinet G and is sandwiched between the rear wall G3 and the sheet metal BK. Therefore, the sub-control board SS is removed from the cabinet G unless the sheet metal BK is removed. Can not do. This enhances the security of the sub-control board SS.

  The locking plate G5221 has claw portions G5221a and G5221b that are claw-shaped and locked to the locked bars G521a and G521b. The claw portions G5221a and G5221b slide in the vertical direction in the cylinder G5222 along with the sliding of the locking plate G5221, so that the locked rod inserted into the openings G5222a and G5222b provided in the cylinder G5222. It is locked to G521a, G521b, or the lock is released.

  An opening (not shown) is formed below the upper door mechanism DU in the cylinder G5222 of the locking portion G522, and a projection (not shown) provided on the locking plate G5221 is formed through the opening. It protrudes inside the cabinet G. The locking plate G5221 is lowered by pulling the projection downward, whereby the locking between the claw portions G5221a and G5221b and the locked bars G521a and G521b can be released.

  Here, the protrusion is slid upward, and is arranged so as to abut on the upper portion of the lower door mechanism DD when the locking plate G5221 is at a height position for locking the upper door mechanism DU.

  According to the above configuration, in a state where the lower door mechanism DD is closed, the upper portion of the lower door mechanism DD physically interferes with the protruding portion, so that the locking plate G5221 is prevented from sliding, and the claw portion G5221a , G5221b and the locked rods G521a, G521b cannot be released, and can be locked so that the upper door mechanism DU cannot be opened.

Further, the MCU 900 receives an operation signal from the touch panel DD19T, and transmits a signal corresponding to the operation signal to the sub-control board SS via the scalar board SK. Thereby, the sub CPU 400 of the sub control board SS recognizes the input operation according to the operation signal from the touch panel DD19T. Although not particularly shown, the sub liquid crystal display device DD19 incorporates a temperature sensor such as a thermistor, and a temperature detection signal from this temperature sensor is transmitted to the sub liquid crystal I / F substrate SL, so that the sub liquid crystal The MCU 900 of the I / F board SL can recognize the temperature during operation.

(Image split display pattern)
In the present embodiment, when displaying an image for production on the sub liquid crystal display device DD19 or performing optical adjustment of the projector device B2, the sub control board SS or the sub control substrate SS is configured to form a divided display pattern as shown in FIG. An image is displayed when the scaler board SK performs signal processing. That is, as shown in FIG. 46, the sub-control board SS includes video data for projector display (data block indicated by “α” of 1280 × 800 resolution) and video data for sub-liquid crystal display (480 × 800 resolution). (Data block indicated by “β”), and transmits an LVDS dual-in signal composed of one combined signal to the scaler board SK.

  The scaler substrate SK generates two video data α, β from the LVDS dual-in signal by the DSF (α), (β) 821, 822 of the multi-output scaler LSI 710, and buffers the video data α, β by SDRAM 712. To be stored temporarily. The video data α and β are developed in the memory space of the SDRAM 712 in an array image as shown on the left side of FIG.

  Thereafter, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into an LVDS1 signal (a video signal indicated by “A” with a resolution of 1280 × 800) through the select area A 801 and the LVDS (1) 811 for projector display. Then, this LVDS1 signal A is transmitted to the projector control board B23. At the same time, the MCU 700 converts the video data β read from the SDRAM 712 into an LVTTL1 signal for sub-liquid crystal display (a video signal indicated by “C” with a resolution of 480 × 800) through the select area C803 and LVTTL (1) 813, This LVTTL1 signal C is transmitted to the sub liquid crystal I / F substrate SL through the V-by-one HS transmitter 711. In this case, the LVDS1 signal A and the LVTTL1 signal C are transmitted at the resolution specified by the sub-control board SS without converting the resolution. Accordingly, the projector B2 can project an image at a resolution equivalent to 1280 × 800 pixels, and the sub liquid crystal display device DD19 can display an image on a screen at a resolution equivalent to 480 × 800 pixels.

  Note that, as the divided display pattern, the modified examples shown in FIGS. 47 to 52 can be realized in accordance with a change in the display mode such as a change in the number of screens (display devices) for displaying an image or a change in the magnification related to the resolution. ing.

(Modification 1)
For example, as shown in FIG. 47, the sub control board SS includes video data for projector display (a data block indicated by “α” of 1280 × 800 resolution) and video data for sub liquid crystal display (1024 × 768 resolution). The data block indicated by “β” is combined, and an LVDS dual-in signal including one combined signal is transmitted to the scaler board SK.

  At this time, the scaler board SK converts the two video data α and β divided by the DSFs (α) and (β) 821 and 822 based on the received LVDS dual-in signal into input data as shown in the left side of FIG. The image is developed in the memory space of the SDRAM 712 with an array image of the pattern 1 or the input pattern 2.

  If the enlargement ratio change (resolution change) is not set, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into the select areas A, B 801 and 802 and the LVDS as shown in the upper right of FIG. (1), (2) Convert to LVDS1 + 2 signal (video signal indicated by “A + B” of 1280 × 800 resolution) through 811 and 812, and transmit this LVDS1 + 2 signal A + B to the projector control board. At the same time, the MCU 700 transmits the video data β read from the SDRAM 712 to the LVTTL1 + 2 signal (“C + D of resolution 1024 × 768”) for the sub liquid crystal display through the select areas C, D803, 804 and LVTTL (1), (2) 813, 814. ), And transmits the LVTTL1 + 2 signal C + D to the sub liquid crystal I / F substrate SL through the V-by-one HS transmitter 711. In this case, the LVDS1 + 2 signal A + B and the LVTTL1 signal C + D are transmitted at the resolution specified by the sub control board SS without converting the resolution. Accordingly, the projector device (for example, WXGA: abbreviation for Wide-XGA) projects an image at a resolution equivalent to 1280 × 800 pixels, and switches the sub-display device DD20 to a sub-liquid crystal display device (for example, XGA: Extended Graphics Array). (Abbreviation), an image can be displayed on the screen at a resolution corresponding to 1024 × 768 pixels.

  On the other hand, when the enlargement ratio change (resolution change) is set, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into the select areas A, B 801 and 802 as shown in the lower right of FIG. Through the LVDS (1) and (2) 811 and 812, for example, it is converted into an LVDS1 + 2 signal A + B having a resolution of 1920 × 1080 according to the set value of the enlargement ratio, and the LVDS1 + 2 signal A + B is transmitted to the projector control board B23.

[Screen Property Control Task]
FIG. 66 shows a screen accessory control task by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 performs a screen accessory test process in order to confirm whether or not the screen mechanisms E1 and F1 operate normally when the power is turned on (S161). For example, as a test, first, the reel screen mechanism E1 is moved to the display position and then to the storage position, and then the reel screen mechanism F1 is moved to the display position and then to the storage position. When an abnormality is detected during the test operation of the screen mechanisms E1 and F1, a display notifying the abnormality is displayed from the projector device B2, and a message notifying the occurrence of the abnormality is requested to be output from the sound control task.

  Next, the sub CPU 400 determines whether or not there is registered screen accessory data (S162). In this process, the sub CPU 400 determines whether or not screen accessory data requesting the operation of the screen mechanisms E1 and F1 exists in a predetermined area of the sub RAM board 41. If there is screen accessory data (S162: Yes), the sub CPU 400 proceeds to the next step S163. If the screen accessory data does not exist (S162: No), the sub CPU 400 proceeds to the process of S164.

  Next, the sub CPU 400 performs a screen accessory operation construction process (S163). In this process, the sub CPU 400 constructs an operation pattern of the screen driving mechanisms E2 and F2 based on the screen accessory data. As an operation pattern of the screen driving mechanisms E1 and F1, for example, when image data is projected on the reel screen mechanism F1 while image data is projected on the front screen mechanism E1 (front screen mechanism When the accessory data for instructing the storage operation to E1 is not registered), the sub CPU 400 that executes the screen accessory operation construction process sets the storage operation pattern of the front screen mechanism E1 and sets the front screen. After the mechanism E1 is stored in the upper part, an operation pattern is constructed in the order in which the reel screen mechanism F1 is moved to the display surface.

  Next, the sub CPU 400 performs a screen accessory control process (S164). This processing will be described later with reference to FIG.

  Next, the sub CPU 400 waits for a period of, for example, 2 msec (S165). Thereafter, the sub CPU 400 shifts to the processing of S162.

[Screen accessory control processing]
FIG. 67 shows a screen accessory control process by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 corresponds to the operation start step and changes in the screen (projection target) from the operation patterns of the screen mechanisms E1 and F1 constructed by the above-described screen accessory operation construction processing. Is determined (S171). When the change of the screen corresponds to the occurrence of the screen change in the operation start step (S171: Yes), the sub CPU 400 shifts to the next process of S172. If it is not the operation start step or does not correspond to the occurrence of a screen change (S171: No), the sub CPU 400 proceeds to the processing of S173.

  Next, the sub CPU 400 performs a focus change request process (S172). This processing will be described later with reference to FIG.

  Next, the sub CPU 400 performs a front screen control process (S173). In this process, the sub CPU 400 controls the operation of the front screen drive mechanism E2 to move the front screen mechanism E1.

  Next, the sub CPU 400 performs a reel screen control process (S174). In this process, the sub CPU 400 controls the operation of the reel screen driving mechanism F2 to move the reel screen mechanism F1.

  Next, the sub CPU 400 determines whether or not the value of the focus standby counter is −1 (S175). The focus standby counter is a subtraction counter for generating a predetermined waiting time when changing the focus position with respect to the projector device B2. When the value of the focus standby counter is −1 (S175: Yes), the sub CPU 400 ends the screen accessory control process. If the value of the focus standby counter is not −1 (S175: No), the sub CPU 400 proceeds to the next step S176.

  Next, the sub CPU 400 determines whether or not the value of the focus standby counter is 0 (S176). If the value of the focus standby counter is 0 (S176: Yes), the sub CPU 400 proceeds to the process of S178. If the value of the focus standby counter is not 0 (S176: No), the sub CPU 400 proceeds to the next step S177.

  Next, the sub CPU 400 subtracts 1 from the value of the focus standby counter (S177). After that, the sub CPU 400 ends the screen accessory control process.

  In S178, the sub CPU 400 requests the projector device B2 to change the focus position after the change. In this processing, the sub CPU 400 stores the focus position setting change request data in the sub device transmission storage area of the sub RAM board 41, and transmits this data to the projector device B2. The focus position setting change request data includes the current focus position before the change and the focus position after the change. Thus, for example, when the projection target of the video is switched from the front screen mechanism E1 to the reel screen mechanism F1, or vice versa, the projector device B2 changes the focus position setting. By controlling the focus mechanism 242 based on the request data, the focus of the projection lens 210 can be adjusted to a focus position corresponding to each of the screen mechanisms E1 and F2.

  Next, the sub CPU 400 sets -1 to the focus standby counter (S179). After that, the sub CPU 400 ends the screen accessory control process.

[Focus change request processing]
FIG. 68 shows a focus change request process by the sub CPU 400 of the sub control board SS. As shown in the drawing, the sub CPU 400 acquires the current focus position (focus position A to E offset) from the current operation state of the screen mechanisms E1 and F1 (S181).

  Next, the sub CPU 400 acquires the changed focus positions (focus positions A to E offset) from the operation patterns of the screen mechanisms E1 and F1 constructed from the registered character data (S182).

  Next, the sub CPU 400 calculates the number of focus change pulses (S183). The number of focus change pulses is the number of pulses of the motor drive signal supplied to the focus motor 242C when changing the focus position, and is the required number of pulses corresponding to the value obtained by subtracting the changed focus position from the current focus position. It is calculated as an absolute value.

  Next, the sub CPU 400 calculates a focus adjustment time (S184). The focus adjustment time is the actual operation time of the focus mechanism 242 for changing the focus position. For example, when the motor drive signal for the focus motor 242C is a pulse square wave having a duty ratio of 0.5, the time (pulse width) of the pulse width is doubled. Cycle) is multiplied by the number of focus change pulses obtained in S183.

  Next, the sub CPU 400 calculates a transmission time (setting change transmission time) for changing the setting of the focus position by communication with the projector control board B23 (S185). The setting change transmission time includes a transmission time 1 for data exchanged between the sub-control board SS and the scaler board SK in accordance with the setting change of the focus position, and a transmission time for data exchanged between the scaler board SK and the projector control board B23. It is calculated as the sum of time 2 and time. The transmission time 1 is obtained by multiplying the number of transmission bits, which is the number of data × (data length + parity + start + stop), by 1 / baud rate 1. Similarly, the transmission time 2 is obtained by multiplying the number of transmission bits by 1 / baud rate 2. In the present embodiment, the baud rate 1 is 38400 bps, the baud rate 2 is 19200 bps, the data length is 8 bits, there is no parity, the start and stop bits are 1 bit, and the transmission time 1 and the transmission time 2 obtained using these numerical values. Is calculated.

  Next, the sub CPU 400 calculates a focus change time (S186). The focus change time is calculated as the sum of the setting change transmission time obtained in S185 and the focus adjustment time obtained in S184.

  Next, the sub CPU 400 determines whether or not to change to the front screen mechanism E1 (S187). In the case of changing to the front screen mechanism E1 (S187: Yes), the sub CPU 400 proceeds to the next step S188. If the change to the front screen mechanism E1 is not made (S187: No), the sub CPU 400 shifts to the processing of S189.

  Next, the sub CPU 400 calculates a movement time 1 for moving the front screen mechanism E1 to a predetermined position (S188). This moving time 1 is the actual working time of the front screen drive mechanism E2. For example, if the motor drive signal for the drive motor E25 of the front screen drive mechanism E2 is a pulse square wave with a duty ratio of 0.5, the pulse width is doubled. The calculated time is multiplied by the required number of motor pulses. After that, the sub CPU 400 proceeds to the process of S190.

  In S189, the sub CPU 400 calculates a moving time 2 for moving the reel screen mechanism F1 to a predetermined position. This movement time 2 is the actual working time of the reel screen drive mechanism F2. For example, if the motor drive signal for the drive motor F24 of the reel screen drive mechanism F2 is a pulse square wave with a duty ratio of 0.5, the pulse width is doubled. The calculated time is multiplied by the required number of motor pulses.

  Next, the sub CPU 400 divides the difference between the movement times 1 and 2 obtained in S188 or S189 and the focus change time obtained in S186 by 2 corresponding to 2 msec of the processing cycle of the screen accessory control task, and calculates A value corresponding to the time is set in the focus standby counter (S190). As a result, regarding the operation of moving the screen mechanisms E1 and F1 to the predetermined position and the operation of changing the focus position, a value that is just the required time difference is not set in the focus standby counter. The focus position can be changed to a predetermined position at the timing when the movement operation of F1 is completed. That is, it is possible to project an image of good image quality with focus on the screen mechanisms E1 and F1 immediately after the movement by changing the focus position.

  Next, the sub CPU 400 determines whether or not there is focus interlocking when displaying an image (for example, “1” when there is a focus interlocking flag (not shown), and “0” when there is no focus interlocking flag) (S191). . The focus interlock means that the focus position is continuously changed in conjunction with the movement of the screen mechanisms E1 and F1. If there is no focus interlock (S191: No), the sub CPU 400 proceeds to the next process of S192. If there is the focus interlock (S191: Yes), the sub CPU 400 ends the focus change request processing.

  Next, the sub CPU 400 sets 0 to the focus standby counter (S192). That is, when the focus linkage is not performed, the focus position is changed immediately at the beginning of the movement of the screen mechanisms E1 and F1, and when the focus linkage is performed, the focus position is changed at the timing when the movement of the screen mechanisms E1 and F1 ends. Changes are completed. After that, the sub CPU 400 ends the focus change request processing.

  Next, the sub CPU 400 acquires a reception command from the main control board MS from the communication message queue (S212).

  Next, the sub CPU 400 determines whether or not there is a received command (S213). If there is a received command (S213: Yes), the sub CPU 400 proceeds to the next process of S214. When there is no reception command (S213: No), the sub CPU 400 shifts to the processing of S218.

  Next, the sub CPU 400 checks the received command (S214).

  Next, the sub CPU 400 determines whether the received command is a valid command (S215). If the received command is a valid command (S215: Yes), the sub CPU 400 proceeds to the next step S216. If the received command is not a valid command (S215: No), the sub CPU 400 proceeds to the process of S218. The validity of the received command means that the value of the command is, for example, in the range of 01H to 10H.

[Sub device reception interrupt processing]
FIG. 74 shows the sub device reception interrupt processing by the sub CPU 400 of the sub control board SS. The sub device reception interruption process is a reception interruption process for taking in communication data transmitted by the scaler board SK in response to an external request from a sub device (sub liquid crystal display device DD19, touch panel DD19T, projector device B2, etc.). As shown in the figure, the sub CPU 400 determines whether or not the data received from the sub device is 'STX' indicating the start of data (S251). If the received data is 'STX (Start of TeXt: 02H)' (S251: Yes), the sub CPU 400 proceeds to the next step S252. If the received data is not “STX” (S251: No), the sub CPU 400 shifts to the processing of S253.

  Next, the sub CPU 400 sets the ETX reception flag and the reception completion flag in the flag storage area of the sub RAM board 41 to "OFF", and clears the sub device reception storage area (S252). After that, the sub CPU 400 ends the sub device reception interrupt processing.

  In S253, sub CPU 400 stores the received data in the sub device reception storage area of sub RAM board 41.

  Next, the sub CPU 400 determines whether or not the data received from the sub device is “ETX” indicating the end of the data (S254). If the received data is “ETX (End of TeXt: 03H)” (S254: Yes), the sub CPU 400 proceeds to the next process of S255. If the received data is not “ETX” (S254: No), the sub CPU 400 proceeds to the process of S256.

  Next, the sub CPU 400 sets the ETX reception flag in the flag storage area of the sub RAM board 41 to "ON" (S255). After that, the sub CPU 400 ends the sub device reception interrupt processing.

  In S256, sub CPU 400 determines whether or not the ETX reception flag in the flag storage area of sub RAM board 41 is "ON".

If the ETX reception flag is not “ON” (S256: No), the sub CPU 400 ends the sub device reception interrupt processing.

  Next, the sub CPU 400 performs a sub device received data sum check process (S257).

  Next, the sub CPU 400 determines whether or not the sum value obtained in S257 is normal (S258). When the sum value is normal (S258: Yes), the sub CPU 400 proceeds to the process of S260. If the sum value is not normal (S258: No), the sub CPU 400 proceeds to the next step S259. Specifically, in the present embodiment, when determining whether or not the sum value is normal, the reception data up to 'ETX', excluding 'STX' of the reception data, is added, and the reception data after 'ETX' is received. By checking the received data, the consistency of the sum value is determined. The method of calculating the sum value is not limited to the addition method, but may be a subtraction method or an exclusive OR (also referred to as BCC).

  Next, the sub CPU 400 discards the data in the sub device reception storage area (clears the sub device reception storage area) (S259). After that, the sub CPU 400 ends the sub device reception interrupt processing.

[Sub device initialization processing]

  Next, the sub CPU 400 copies the value of the scalar set value storage area of the SRAM 401 to the scalar set value storage area of the sub RAM board 41 (S272). As shown in FIG. 62, the scalar setting values are the output screen division setting number, input screen division setting number, output screen 1 to 4 horizontal resolution, output screen 1 to 4 vertical resolution, input screen 1 and 2 horizontal resolution, input screen 1 This corresponds to a device profile indicating control characteristics of the scalar board SK such as the screen 1 and the vertical resolution.

  Next, the sub CPU 400 determines whether or not all the scalar setting values in the scalar setting value storage area are within the effective range (S274). The effective range of the scaler set value is defined in advance as a transmission command from the sub-control board SS, as shown in FIG. When all the scaler setting values are within the valid range (S274: Yes), the sub CPU 400 proceeds to the process of S276. If at least one of the scaler setting values is not within the valid range (S274: No), the sub CPU 400 proceeds to the next step S275.

  Next, the sub CPU 400 initializes the scalar set value storage area of the SRAM 401 and the scalar set value storage area of the sub RAM board 41 as initial values (S275). As shown in FIG. 62, the initial value of the scaler setting value is written in the scaler initial value area of the sub-ROM board 42 in advance.

  Next, the sub CPU 400 copies the value of the sub liquid crystal set value storage area of the SRAM 401 to the sub liquid crystal set value storage area of the sub RAM board 41 (S276). As shown in FIG. 62, the sub liquid crystal set value corresponds to a device profile indicating the display characteristics of the sub liquid crystal display device DD19, such as the sub liquid crystal horizontal resolution, the sub liquid crystal vertical resolution, and the sub liquid crystal luminance.

If all the sub liquid crystal setting values are within the effective range (S278: Yes), the sub CPU 400 proceeds to the process of S280. If at least one sub liquid crystal setting value is not within the valid range (S278: No), the sub CPU 400 proceeds to the next step S279.

  Next, the sub CPU 400 initializes the sub liquid crystal set value storage area of the SRAM 401 and the sub liquid crystal set value storage area of the sub RAM board 41 as initial values (S279). The initial value of the sub liquid crystal setting value is written in advance in the sub liquid crystal initial value area of the sub ROM board 42 as shown in FIG.

  Next, the sub CPU 400 copies the value of the projector setting value storage area of the SRAM 401 to the projector setting value storage area of the sub RAM board 41 (S280). As shown in FIG. 62, the projector setting values are the horizontal position A to E adjustment value, the horizontal position A to E offset, the vertical position A to E adjustment value, the vertical position A to E offset, and the focus position offset. A to E, LED brightness setting, trapezoidal distortion correction value, white color temperature setting, brightness setting, contrast setting, gamma setting, and focus drift correction values A to E correspond to device profiles indicating display characteristics of the projector B2.

  Next, the sub CPU 400 determines whether or not all the projector setting values in the projector setting value storage area are within the valid range (S282). When all the projector setting values are within the valid range (S282: Yes), the sub CPU 400 proceeds to the process of S284. If at least one of the projector setting values is not within the valid range (S282: No), the sub CPU 400 proceeds to the next process of S283.

  Next, the sub CPU 400 initializes the projector setting value storage area of the SRAM 401 and the projector setting value storage area of the sub RAM board 41 as initial values (S283). The initial values of the projector setting values are written in advance in the projector initial value area of the sub ROM board 42 as shown in FIG.

  Next, the sub CPU 400 sets the scaler setting completion flag, the sub liquid crystal setting completion flag, and the projector setting completion flag in the flag storage area of the sub RAM board 41 to "OFF" (S284). After that, the sub CPU 400 ends the sub device initialization processing.

[Scalar control processing]
FIG. 76 shows a scaler control process by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 determines whether or not the transmission source ID of the reception data temporarily stored in the sub device reception storage area of the sub RAM board 41 indicates “scaler (ID: 02H shown in FIG. 53)”. Is determined (S291). When the transmission source ID indicates 'scaler' (S291: Yes), the sub CPU 400 shifts to the next processing of S292. When the transmission source ID does not indicate 'scaler' (S291: No), the sub CPU 400 ends the scaler control process.

  Next, the sub CPU 400 performs a received data consistency check process for controlling the scaler board SK (S292). In this processing, the sub CPU 400 checks whether or not the value of the command ID included in the received data matches the value of '01H' to '05H' indicating the transmission command from the scaler board SK shown in FIG. And returns the check result as a return value.

  Next, the sub CPU 400 determines whether there is an abnormality in the consistency of the received data from the return value of the check result (S293). When there is an abnormality in the consistency of the received data (S293: Yes), the sub CPU 400 shifts to the next processing of S294. If there is no abnormality in the consistency of the received data (S293: No), the sub CPU 400 proceeds to the process of S295.

  Next, because the consistency of the received data is abnormal (invalid received data), the sub CPU 400 discards (clears) the data in the sub device reception storage area (S294). Thereafter, the sub CPU 400 ends the scaler control process.

  In S295, the sub CPU 400 performs a process at the time of receiving scaler control. This processing will be described later with reference to FIG. Thereafter, the sub CPU 400 ends the scaler control process.

[Processing when receiving scaler control]
FIG. 77 shows a process at the time of receiving scaler control by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 copies the received data from the sub device reception storage area of the sub RAM board 41 to the scaler control reception storage area (S301).

  Next, the sub CPU 400 determines whether or not the command (reception command) acquired from the reception data is “start parameter request” (S302). If the received command is “start parameter request (see CMD: 01H shown in the left column of FIG. 54)” (S302: Yes), the sub CPU 400 proceeds to the next step S303. If the received command is not the “start parameter request” (S302: No), the sub CPU 400 proceeds to the processing of S304.

  Next, the sub CPU 400 performs a process at the time of receiving a scaler activation parameter request (S303). This processing will be described later with reference to FIG. Thereafter, the sub CPU 400 ends the process at the time of receiving the scaler control.

  In S304, sub CPU 400 determines whether or not the command (received command) acquired from the received data is “parameter request (see CMD: 02H shown in the left column of FIG. 54)”.

(Memory map of scaler board SK)
As shown in FIGS. 96 and 97, various information is stored in the ROM included in the SDRAM 712 and the MCU 700 of the scaler board SK. The various storage areas shown in FIGS. 96 and 97 do not show all information used in the scaler board SK. For example, a control program executed by the MCU 700 of the scaler board SK, a work area used by the MCU 700, and the like are not illustrated in FIGS.

  As shown in FIG. 96, the SDRAM 712 has a first command for receiving each command in order to exchange commands with the sub control board SS, the projector control board B23, and the sub liquid crystal I / F board SL. To a third reception storage area, a first to third transmission storage area for transmitting a command to each of them, a scalar LSI setting storage area, a status storage area, a flag other storage area, and a multiple output scalar LSI 710 relating to the multi-output scalar LSI 710. And a scaler LSI use area of an MCU (control LSI) 700. For example, in the scaler LSI setting storage area, output first to fourth screen horizontal resolutions, output first to fourth screen vertical resolutions, input first and second screen horizontal resolutions, and output first and second screen vertical resolutions are stored. You. The flag and other storage areas store first to third reception completion flags, first to third EXT reception flags, scalar LSI setting flags, reset request flags, transmission cycle counters, error management areas, and self-diagnosis storage areas. These stored information will be described later.

  As shown in FIG. 97, in the ROM of the MCU 700, the output division number, the input division number, the output first to fourth screen horizontal resolution, and the output first to fourth screen vertical resolution are stored as the scaler LSI initial setting values. , The input first and second screen horizontal resolutions, and the input first and second screen vertical resolutions are stored, and the first to third line baud rates, the first to third line data lengths, and the To the third line parity, the first to third line stop, and a diagnostic value (55AAH) as a value for self-diagnosis.

(Treatment of the scaler substrate SK)
[Scalar board main processing by MCU 700]
FIG. 98 shows a scalar substrate main process by the MCU 700 of the scalar substrate SK. As shown in the figure, when the power is turned on, the MCU 700 performs an initialization process of the scaler board SK (S561). This processing will be described later with reference to FIG.

  Next, the MCU 700 determines whether the first reception completion flag in the flag and other storage areas of the SDRAM 712 is “ON” (S562). When the first reception completion flag is “ON” (S562: Yes), the MCU 700 shifts to the next process of S563. If the first reception completion flag is not “ON” (S562: No), the MCU 700 shifts to the processing of S568.

  Next, the MCU 700 acquires the reception data (command) from the first reception storage area of the SDRAM 712 (S563).

  Next, the MCU 700 sets the first reception completion flag in the flag and other storage areas to “OFF” (S564).

  Next, the MCU 700 determines whether or not the transmission destination ID of the obtained received data indicates 'scaler (see ID: 30H shown in FIG. 53)' (S565). If the destination ID indicates 'scaler' (S565: Yes), the MCU 700 shifts to the processing of S567. If the transmission destination ID does not indicate 'scaler' (S565: No), the MCU 700 proceeds to the next step S566.

  Next, the MCU 700 waits for a reset of the watchdog timer (WDT) (S572). Waiting for the reset of the watchdog timer is a process of performing an infinite loop process without clearing (or setting a predetermined value to) the watchdog timer and waiting for the watchdog timer to output a reset signal to the MCU 700. When the timer outputs a reset signal to the MCU 700, the MCU 700 is reset, so that the process is restarted from the first step (S561) in the scalar board main process (also referred to as “reboot”). The same applies to S700 of the projector control main process described later and S871 of the sub liquid crystal control main process.

  In S573, the MCU 700 clears the value of the watchdog timer (WDT).

  Next, the MCU 700 waits for a period of, for example, 2 msec (S574). Thereafter, the MCU 700 shifts to the processing of S562.

  In S586, the MCU 700 determines whether the first ETX reception flag in the flag or other storage area of the SDRAM 712 is "ON". If the first ETX reception flag is “ON” (S586: Yes), the MCU 700 proceeds to the next processing of S587. If the first ETX reception flag is not “ON” (S586: No), the MCU 700 ends the first serial line reception interrupt processing.

  Next, the MCU 700 performs a received data sum check process (S587).

  Next, the MCU 700 determines whether the sum value obtained in S587 is normal (S588). If the sum value is normal (S588: Yes), the MCU 700 proceeds to the process of S590. If the sum value is not normal (S588: No), the MCU 700 shifts to the next step S589.

  Next, the MCU 700 acquires various initial setting values related to input / output of the multi-output scaler LSI 710 from the ROM (S603).

  Next, the MCU 700 performs an initial setting relating to the input / output of the multi-output scaler LSI 710 (S604). In this process, the MCU 700 performs initial settings on the DSF (α) 821 and DSF (β) 822 and the select areas A to D 801 to 804 of the multi-output scaler LSI 710 based on the initial settings obtained from the ROM.

As shown in the figure, the MCU 700 determines whether or not the destination ID of the received data indicates “projector (30H)” (S611). If the transmission destination ID indicates 'projector' (S611: Yes), the MCU 700 proceeds to the next step S612. If the transmission destination ID does not indicate “projector” (S611: No), the MCU 700 shifts to the processing of S614.

  Next, the MCU 700 copies the data once taken into the first reception storage area of the SDRAM 712 to the second transmission storage area (S612).

  Next, the MCU 700 copies the data once taken into the first reception storage area of the SDRAM 712 to the third transmission storage area (S615).

  Next, the MCU 700 performs a third serial line transmission process (S616). In this process, the MCU 700 outputs data transmitted from the sub control board SS to the sub liquid crystal I / F board SL to the third serial line. After that, the MCU 700 ends the sub-device bypass transmission process.

[Processing during reception between sub-control and scaler]
FIG. 102 shows a process at the time of reception between the sub-controller and the scaler by the MCU 700 of the scaler board SK. As shown in the figure, the MCU 700 transmits a command (CMD) of received data (hereinafter, referred to as “acquired received data”) acquired from the first reception storage area of the SDRAM 712 from the sub-control board SS in S563. It is determined whether or not a status request (see CMD: 03H shown in the right column of FIG. 54) '(S621). When the command of the acquired received data is “status request” (S621: Yes), the MCU 700 proceeds to the next process of S622.

  Next, the MCU 700 stores various parameter values (D1) included in the obtained received data in the status storage area of the SDRAM 712 (S623). Thereafter, the MCU 700 ends the processing at the time of reception between the sub control and the scaler.

  In S624, the MCU 700 determines whether or not the command of the acquired received data is "setting completed (see CMD: 02H shown in the right column of FIG. 54)". If the command of the acquired received data is “setting completed” (S624: Yes), the MCU 700 proceeds to the process of the next S625. If the command of the acquired received data is not “setting completed” (S624: No), the MCU 700 proceeds to the process of S626.

  In S628, the MCU 700 determines whether or not the command of the acquired received data is “the output screen division setting number (see CMD: 05H shown in the right column of FIG. 54)”. If the command of the acquired received data is “the number of output screen division settings” (S628: Yes), the MCU 700 proceeds to the next process of S629. If the command of the acquired received data is not the “output screen division setting number” (S628: No), the MCU 700 proceeds to the process of S630.

  Next, the MCU 700 stores the output screen division setting number included in the acquired reception data in the scalar LSI setting storage area of the SDRAM 712 (S629). Thereafter, the MCU 700 shifts to the processing of S636.

  In S630, the MCU 700 determines whether the command of the acquired received data is “output screen resolution setting (see CMD: 06H shown in the right column of FIG. 54)”.

  Next, the MCU 700 registers a transmission request of a command indicating "reception confirmation (see CMD: 04H shown in the left column of FIG. 54)" in the sub-control board SS (S636). Thereafter, the MCU 700 ends the processing at the time of reception between the sub control and the scaler.

[Scalar self-diagnosis processing]

  Next, the MCU 700 determines whether the value (load value) read from the self-diagnosis storage area correctly matches the diagnosis value (S642). If the load value matches the diagnostic value (S642: Yes), the MCU 700 proceeds to the process of S644. If the load value does not match the diagnostic value (S642: No), the MCU 700 proceeds to the next step S643.

  Next, the MCU 700 determines whether the status of the multi-output scaler LSI 710 is normal (S645). If the status of the multi-output scaler LSI 710 is normal (S645: Yes), the MCU 700 shifts to the processing of S647. If the status of the multi-output scaler LSI 710 is not normal (S645: No), the MCU 700 shifts to the next process of S646.

  Next, the MCU 700 sets “WDT (watchdog timer) -scalar abnormality” as error data in the error management area of the SDRAM 712 (S646).

  Next, the MCU 700 reads the output settings of the multi-output scaler LSI 710 (S647).

If the output setting data of the SDRAM 712 and the actual output setting have the same setting value (S648: Yes), the MCU 700 shifts to the processing of S650. If the output setting data of the SDRAM 712 is different from the actual output setting (S648: No), the MCU 700 proceeds to the next step S649.

  Next, the MCU 700 sets “scalar output setting error” as error data in the error management area of the SDRAM 712 (S649).

  Next, the MCU 700 reads the input settings of the multi-output scaler LSI 710 (S650).

[Processing during transmission between sub-controller and scaler]
FIG. 104 shows a process at the time of transmission between the sub-controller and the scaler by the MCU 700 of the scaler board SK. As shown in the drawing, the MCU 700 adds 1 to the transmission cycle counter (S661). This transmission cycle counter is an addition counter for measuring a cycle of transmitting a command from the scaler board SK.

  Next, the MCU 700 determines whether or not the value of the transmission cycle counter is, for example, 100 or more as a predetermined value (S662). If the value of the transmission cycle counter is equal to or more than the predetermined value (S662: Yes), the MCU 700 proceeds to the next process of S663. When the value of the transmission cycle counter is less than the predetermined value (S662: No), the MCU 700 ends the processing at the time of transmission between the sub control and the scaler. In the present embodiment, since the processing is performed at a cycle of 2 msec in the above-described scalar board main processing, the value of the transmission cycle counter of 100 or more means 2 msec × 100 = 200 msec or more. As a result, data is transmitted to the sub-control board SS at a cycle of approximately 200 msec. However, the present invention is not limited to this, and the predetermined value of the transmission cycle counter may be any value (for example, transmission cycle counter: 50 × 2 msec). = 100 msec cycle).

  Next, the MCU 700 clears the value of the transmission cycle counter (S663).

  Next, the MCU 700 determines whether or not the flag of the SDRAM 712 and the scalar LSI setting flag in the storage area are “OFF” (S664). When the scaler LSI setting flag is “OFF” (S664: Yes), the MCU 700 proceeds to the next process of S665. If the scalar LSI setting flag is not “OFF” (S664: No), the MCU 700 proceeds to the process of S666.

  Next, the MCU 700 creates, as transmission data, a command indicating “start parameter request (see CMD: 01H shown in the left column of FIG. 54)” to the sub-control board SS (S665). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub-control board SS by a first serial line transmission process of S676 described later. After the processing of S665, the MCU 700 shifts to the processing of S676.

  In S666, the MCU 700 determines whether or not error data exists in the error management area of the SDRAM 712. If there is error data in the error management area (S666: Yes), the MCU 700 proceeds to the next step S667. If no error data exists in the error management area (S666: No), the MCU 700 shifts to the processing of S669.

  Next, the MCU 700 creates a command indicating "error notification (see CMD: 05H shown in the left column of FIG. 54)" as transmission data for the sub-control board SS (S667). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub-control board SS by a first serial line transmission process of S676 described later.

  Next, the MCU 700 sets the flag of the SDRAM 712 and the reset request flag in the storage area to “ON” (S668). Thereafter, the MCU 700 shifts to the processing of S676.

  In S669, the MCU 700 determines whether or not there is a request to send a command indicating “reception confirmation (see CMD: 04H shown in the left column of FIG. 54)” to the sub-control board SS. If there is a transmission request of a command indicating “acknowledgment” (S669: Yes), the MCU 700 proceeds to the next step S670. If there is no transmission request of the command indicating “acknowledgment” (S669: No), the MCU 700 proceeds to the process of S671.

  Next, the MCU 700 creates a command indicating “acknowledgment” to the sub-control board SS as transmission data (S670). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub-control board SS by a first serial line transmission process of S676 described later. After the processing of S670, the MCU 700 shifts to the processing of S676.

  In S671, the MCU 700 determines whether there is a request to send a command indicating “status (see CMD: 03H shown in the left column of FIG. 54)” to the sub-control board SS. If there is a transmission request for a command indicating “status” (S671: Yes), the MCU 700 proceeds to the next process of S672. If there is no transmission request of the command indicating “status” (S671: No), the MCU 700 shifts to the processing of S675.

  Next, the MCU 700 determines whether or not the data in the status storage area of the SDRAM 712 is data related to output settings (S672). If the data in the status storage area is data relating to the output setting (D1: 01H) (S672: Yes), the MCU 700 proceeds to the next step S673. If the data in the status storage area is not the data related to the output setting, that is, the data related to the input setting (D1: 02H) (S672: No), the MCU 700 shifts to the processing of S674.

  Next, the MCU 700 creates, as transmission data, a command indicating “status” related to the output setting for the sub-control board SS (S673). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub-control board SS by a first serial line transmission process of S676 described later. After the processing in S673, the MCU 700 proceeds to the processing in S676.

  In step S674, the MCU 700 creates a command indicating “status” related to the input setting for the sub-control board SS as transmission data. This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub-control board SS by a first serial line transmission process of S676 described later. After the processing of S674, the MCU 700 shifts to the processing of S676.

  In S675, the MCU 700 creates a command indicating 'parameter request' to the sub-control board SS as transmission data. This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub-control board SS by the first serial line transmission processing of the next S676.

  Next, the MCU 700 performs a first serial line transmission process (S676). By this transmission processing, various commands are transmitted from the scaler board SK to the sub-control board SS. Thereafter, the MCU 700 ends the processing at the time of transmission between the sub control and the scaler.

[Sub-control bypass transmission processing]

If the acquired FAN rotation speed is not normal (S798: No), the control LSI 230 proceeds to the next process of S799.

  Next, the control LSI 230 sets "FAN rotation abnormality" as error data in the error management area of the DRAM (S799). Specifically, similarly to the LED temperature abnormality described above, the FAN rotation abnormality is set according to the condition of the FAN1 to 4 rotation abnormality in the projector control board error information shown in FIG.

  Next, the control LSI 230 performs a projector power supply diagnosis process (S800). In this process, the control LSI 230 detects the operating voltage supplied to the projector device B2.

  Next, the control LSI 230 determines whether the operating voltage of the projector B2 is equal to or higher than a specified voltage (S801). If the operating voltage of the projector B2 is equal to or higher than the specified voltage (S801: Yes), the control LSI 230 proceeds to the processing of S803. When the operating voltage of the projector B2 is lower than the specified voltage (S801: No), the control LSI 230 proceeds to the next process of S802.

  Next, the control LSI 230 sets "voltage abnormality" as error data in the error management area of the DRAM (S802). Specifically, as in the case of the LED temperature abnormality described above, the voltage abnormality is set in accordance with the voltage abnormality condition of the projector control board error information shown in FIG.

Specifically, similarly to the LED temperature abnormality described above, the DLP abnormality is set in accordance with the WDT-DLP condition of the projector control board error information shown in FIG.

  Next, the control LSI 230 determines whether data indicating “LED temperature abnormality” (forced shutdown), “FAN rotation abnormality”, or “voltage abnormality” is set in the error management area (S806). . If data indicating any of the above-mentioned abnormalities is set in the error management area (S806: Yes), the control LSI 230 proceeds to the next process of S307. If none of the data indicating the abnormality is set in the error management area (S806: No), the control LSI 230 ends the projector self-diagnosis processing.

Then, a drive stop command is issued (S807). Thereby, the operation of the projector device B2 is stopped. After that, the control LSI 230 ends the projector self-diagnosis processing. In the present embodiment, the operation of the projector device B2 is stopped when data indicating "LED temperature abnormality", "FAN rotation abnormality", or "voltage abnormality" is set in the error management area. However, the power must be turned off for recovery, but this is not limiting, and the operation of the projector B2 may be restarted when the occurring abnormality is recovered while the operation of the projector B2 is stopped.

  Next, the MCU 900 determines whether or not the ON state of the touch panel DD19T (the state of touch, flick, or pinch) is detected for 30 minutes or more (S934). If the ON state of the touch panel DD19T has been detected for 30 minutes or longer (S934: Yes), the MCU 900 proceeds to the next step S935. If the state is not detected for more than 30 minutes (S934: No), the MCU 900 shifts to the processing of S936.

  Next, the MCU 900 performs a sub liquid crystal operation stop process (S937). Thereby, the operations of the sub liquid crystal display device DD19 and the touch panel DD19T are stopped. After that, the MCU 900 ends the sub-liquid crystal self-diagnosis processing.

[Transmission processing between sub control and sub liquid crystal]
FIG. 122 shows a sub control-sub liquid crystal transmission process by the MCU 900 of the sub liquid crystal I / F substrate SL. As shown in the drawing, the MCU 900 adds 1 to the transmission cycle counter (S941).

This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub-control board SS by a third serial line transmission process of S956 described later. After the processing of S948, the MCU 900 shifts to the processing of S956.

  In S949, the MCU 900 determines whether or not there is a transmission request of the 'acknowledgment' command to the sub-control board SS. If there is a transmission request for the 'acknowledgment' command (S949: Yes), the MCU 900 shifts to the next step S950. When there is no transmission request of the 'reception confirmation' command (S949: No), the MCU 900 shifts to the processing of S951.

  Next, the MCU 900 creates transmission data of a 'reception confirmation (see CMD: 44H shown in the left column of FIG. 55)' command for the sub-control board SS (S950). This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub-control board SS by a third serial line transmission process of S956 described later. After the processing of S950, the MCU 900 shifts to the processing of S956.

  In S951, the MCU 900 determines whether or not there is a transmission request of a “status” command to the sub-control board SS. If there is a transmission request for the 'status' command (S951: Yes), the MCU 900 shifts to the next process of S952. If there is no transmission request of the 'status' command (S951: No), the MCU 900 shifts to the processing of S955.

  Next, the MCU 900 determines whether or not the data type of the status storage area of the DRAM is related to touch input (S952). If the data type of the status storage area is related to touch input (S952: Yes), the MCU 900 shifts to the next process of S953. If the data type of the status storage area is not related to touch input, that is, related to liquid crystal setting (S952: No), the MCU 900 shifts to the processing of S954.

  Next, the MCU 900 adds the data of the touch panel input area to the “status (CMD: 43H shown in the left column of FIG. 55)” command related to the touch input to the sub-control board SS to create transmission data (S953). ). This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub-control board SS by a third serial line transmission process of S956 described later.

  In S954, the MCU 900 creates transmission data of a command indicating “status (see CMD: 43H shown in the left column of FIG. 55)” related to the liquid crystal setting for the sub-control board SS. This transmission data is stored in the third transmission storage area of the DRAM, and is transmitted as a transmission command to the sub-control board SS by a third serial line transmission process of S956 described later. After the processing of S954, the MCU 900 shifts to the processing of S956.

  In S955, the MCU 900 creates transmission data of a command indicating “parameter request (see CMD: 42H shown in the left column of FIG. 55)” to the sub-control board SS. This transmission data is stored in the third transmission storage area of the DRAM, and is transmitted as a transmission command to the sub-control board SS by the third serial line transmission process of S956.

  Next, the MCU 900 performs a third serial line transmission process (S956). By this transmission processing, various commands are transmitted from the sub liquid crystal I / F substrate SL to the sub control substrate SS via the scaler substrate SK. Thereafter, the MCU 900 ends the transmission process between the sub control and the sub liquid crystal.

(Optical adjustment of projector device B2)
FIG. 123 is a diagram showing a test pattern projected at the time of optical adjustment of the projector device B2. A factory inspector (also referred to as a quality assurance officer) starts application software for optical adjustment on the adjustment PC 1000 and performs a predetermined operation in accordance with a menu of the software, thereby fixing the fixed screen mechanism D and the front screen mechanism E1. Alternatively, the test pattern TP as shown in FIG. 123 can be displayed on each projection plane by operating the reel screen mechanism F1. FIG. 123 shows a state in which the test pattern TP is displayed on the reflection part D1 of the fixed screen mechanism D as an example. The factory inspection worker can observe such a display mode of the test pattern TP from the upper display window UD1 of the gaming machine 1.

  The test pattern TP is, for example, a color pattern in which SMPTE (Society of Motion Picture and Television Engineers) color bars are sprite in a circle and small circular patterns in four corners are arranged on a cross hatch pattern in the background. It is.

  Specifically, the factory inspector operates so that any one of the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1 becomes a projection target, and every time the projection target is switched, While observing the display mode of the test pattern TP, the projector device B2 can be adjusted so that the display mode is appropriate. Thereby, for the projector device B2, the horizontal position adjustment value, the vertical position adjustment value, the focus position adjustment value, the LED luminance setting, the keystone distortion correction value, the white color temperature setting, the brightness setting, the contrast setting, the gamma setting, the test Optical adjustment can be performed for each item such as a pattern, a horizontal position offset, a vertical position offset, and a focus position offset.

  In the present embodiment, at the time of adjustment work before assembling the gaming machine, for example, identification symbols 'A' to 'C' are assigned to each of the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1, Using these identification symbols, horizontal position A to C adjustment values, vertical position A to C adjustment values, and focus positions A to C adjustment values that are different for each projection target are set in the EEPROM 231 of the projector control board B23. Other adjustment items (LED brightness setting, keystone distortion correction value, white color temperature setting, brightness setting, contrast setting, gamma setting, test pattern, horizontal position offset, vertical position offset, focus position offset) After being assembled, it is set in the SRAM 401 of the sub-control board SS. It should be noted that the horizontal position offset, the vertical position offset, and the focus position offset can be changed by a maintenance worker at a site such as a game arcade by adjusting the offset at a factory or the like.

  On the other hand, FIG. 124 is a diagram showing a test pattern TP 'and the like displayed on the screen (the touch panel DD19T) of the sub liquid crystal display device DD19 at the time of optical adjustment of the projector device B2 at the site such as a game arcade. After the gaming machine 1 is installed in a game arcade or the like, a test operation such as a test pattern TP ′ can be displayed on the touch panel DD19T serving as a screen of the sub liquid crystal display device DD19 by performing a predetermined operation by a maintenance worker. . The maintenance worker can appropriately and individually perform optical adjustment of the projector device B2 using such a test pattern TP '.

  The test pattern TP 'displayed on the touch panel DD19T is different from the test pattern TP directly displayed on the projection target, and is displayed as an operation target that can be intuitively deformed as a virtual image by simulation. In addition, buttons T1 and T2 for changing the horizontal position offset, the vertical position offset, the focus position offset, and the focus drift correction for each projection target are displayed on the touch panel DD19T, as well as trapezoidal distortion correction and LED brightness. , A button T3 for changing the setting of the white color temperature, brightness, contrast, and gamma value, an indicator T4, and a numeric keypad T5 for inputting various numerical values are also displayed.

  More specifically, the maintenance worker performs a predetermined operation to display the test pattern TP 'or the like on the touch panel DD19T, and any one of the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1 projects. Operate to be targeted. Thereafter, the maintenance operator selects one of the horizontal position offset, the vertical position offset, the focus position offset, and the focus drift correction by operating the buttons T1 and T2, and directly performs the test pattern TP ′ by operating the touch panel. Adjustment can be performed while changing the display mode so that the display mode is appropriate. That is, the display position of the test pattern TP 'changes vertically and horizontally and the image quality changes according to the operation of the maintenance worker. Thus, with respect to the projector device B2, it is possible to change the setting of the horizontal position offset, the vertical position offset, the focus position offset, and the focus drift correction for each different projection target. At this time, the maintenance operator can also observe the actual test pattern TP since the test pattern TP is simultaneously projected from the projector device B2 onto the national screen mechanism D. The horizontal position offset, the vertical position offset, the focus position offset, and the focus drift correction are set in a projector setting value storage area of the SRAM 401 of the sub control board SS and a projector setting value storage area of the sub RAM board 41.

  The maintenance operator operates the button T3 and the numeric keypad T5 while observing the test pattern TP 'together with the actual test pattern TP, so that the trapezoidal distortion correction, LED brightness, white color temperature, brightness, contrast, and gamma value are performed. Settings can also be changed for each of these items by directly entering numerical values. At this time, the test pattern TP 'changes its overall shape or its color tone according to the operation of the maintenance worker. The values of the items such as the trapezoidal distortion correction, the LED brightness, the white color temperature, the brightness, the contrast, and the gamma value, which have been changed in this manner, are stored in the projector setting value storage area of the SRAM 401 of the sub control board SS and the sub RAM board 41 Is set in the projector setting value storage area.

  Next, a modified example of the present invention will be described. Note that components that are the same as or similar to those according to the above-described embodiments are given the same reference numerals, and descriptions thereof are omitted.

(Cooling structure of projector device)
FIG. 125 shows a first modification of the projector device. The projector device X shown in the figure has a bottom plate X21 and a cover case X22. As described above, a lens unit B21 (partially omitted) including the projection lens 210, an LED light source (240R, 240G, 240B) and a DMD (inside) are provided in the interior partitioned by the bottom plate X21 and the cover case X22. 241) is provided, and further, an exhaust fan 245, heat radiating plates 2430 and 2431, and a heat sink 243Xa are provided. A heat sink 243Xc is provided outside the cover case X22 so that the heat sink 243Xc is externally exposed. One surface (the front surface in FIG. 125) of the cover case X22 is provided with an opening X22B for guiding irradiation light from the projection lens 210 to the outside. Note that the projector device X of the first modified example is directly attached to the upper surface wall G4 of the cabinet G, and is provided so as to directly guide irradiation light to the projection target without using a mirror.

  An LED light source (240Ra, 240Ga, 240Ba) (not shown) and a DMD substrate (241a) are provided on one surface (the lower surface in FIG. 125) of the heat radiating plate 2430 so as to be in contact therewith. Another radiator plate 2431 is arranged on the other side (upper surface in FIG. 125) of the radiator plate 2430 so as to overlap, and the two radiator plates 2430 and 2431 are surfaced with screws. A heat conductive sheet (or heat conductive gel) is attached to the surface where the heat radiating plate 2430 and the heat radiating plate 2431 are in contact with each other, and a tap for fixing a screw is cut into the heat radiating plate 2430 in a screw shape (not shown). Zu). A mounting hole for screwing with a screw is provided on the upper surface of the heat sink 2431. Further, by removing the screw of the heat sink 2431, the heat pipe 243Xd and the heat sink 243Xc can be removed. The heat radiating plate 2430 is connected to transmit heat generated by the LED light source and the DMD substrate to the heat sink 243Xa via the heat pipe 243Xb. The heat radiated into the air by the heat sink 243Xa is forcibly discharged by the exhaust fan 245 through an exhaust port X22D provided in the cover case X22.

  On the other hand, the heat radiating plate 2431 is connected to transfer heat to the heat sink 243Xc via the heat pipe 243Xd. The heat pipe 243Xd extends from the inside of the cover case X22 to the outside through a hole X22A provided in the cover case X22, and is connected to a heat sink 243Xc provided outside. That is, the heat radiating plate 2431 is connected so as to receive the heat generated by the LED light source and the DMD substrate from the heat radiating plate 2430 and further transmit the heat to the heat sink 243Xc via the heat pipe 243Xd. As a result, the heat generated by the LED light source and the DMD substrate is transmitted to the heat sink 243Xc located outside the cover case X22 through the radiator plate 2431 and the heat pipe 243Xd. The heat is exhausted. With such an external heat sink 243Xc, it is also possible to effectively eliminate a heat pool inside the projector device X and prevent overheating of optical components such as lenses.

  FIG. 126 shows a second modification of the projector device. A projector device X ′ shown in the figure has a bottom plate X21 and a cover case X22 and a lens unit B21 (partially not shown) including a projection lens 210 therein similarly to the above-described first modification. And an optical mechanism (not shown) including an LED light source (240R, 240G, 240B) and a DMD (241), and an exhaust fan 245, a heat radiating plate 2430, and heat sinks 243Xa and 243Xc. I have. The heat sink 243Xc is different from that according to the above-described first modification example, and is arranged as follows.

  The heat sink 243Xc is directly joined to one surface (the upper surface in FIG. 126) of the heat radiating plate 2430, and is provided so that heat is directly transmitted from the heat radiating plate 2430. Further, the fin portion of the heat sink 243Xc is exposed to the outside through an opening X22C provided on one surface (the upper surface in FIG. 126) of the cover case X22. According to the arrangement structure of the heat sink 243Xc, the heat generated in the LED light source and the DMD substrate is efficiently transmitted to the fin portion of the heat sink 243Xc located outside the cover case X22 through the heat radiating plate 2430. The heat will be exhausted outside. The heat sink 243Xc having the fin portion exposed to the outside can also effectively eliminate the heat pool inside the projector device X and prevent overheating of optical components such as a lens.

  FIG. 127 illustrates an arrangement form of a projector device according to a third modification. Although the detailed structure of the projector device X ″ shown in the drawing is not shown, the same structure as that of the projector device X ′ shown in FIG. 126 described above is employed except that a heat sink exposed to the outside is not provided. That is, in the projector device X ", a heat sink 2430 is provided so as to face the opening X22C of the cover case X22 instead of the heat sink 243Xc described above, and the upper surface of the heat sink 2430 slightly protrudes from the opening X22C. It is exposed (not shown in FIG. 127). In such a projector device X ″, the heat radiating plate 2430 exposed from the opening X22C of the cover case X22 is connected to the upper surface wall G4 of the cabinet G via a metal heat conducting member Y, and the upper surface wall G4 is not shown. The upper surface wall G4 is made of a metal plate member having a high thermal conductivity, such as stainless steel, etc. According to such a mounting structure of the projector device X ″, the upper surface wall G4 is formed inside the device. Heat is efficiently transmitted to the upper surface wall G4 through the heat radiating plate 2430 and the heat conducting member Y, and the upper surface wall G4 itself functions as a heat radiating member. To prevent overheating of optical components such as lenses.

  FIG. 128 shows a circuit configuration of a projector device applied to a modification after a fourth modification described later. Note that the projector device B2 as shown in FIG. 33 is also applied to the fourth and subsequent modifications. Therefore, the same components as those described above are denoted by the same reference numerals and description thereof will be omitted.

  As shown in FIG. 128, a projector device B2 applied to the fourth and subsequent modifications includes, as electrical components, a first temperature sensor B25a, a second temperature sensor B25b, an intake temperature sensor B26a, and an exhaust temperature sensor. A temperature sensor B26b and a plurality of pulse sensors B27a, B27b, B27c are included. In addition, power is supplied to the projector device B2 to the intake fans 244A (FAN1) and 244B (FAN2), the exhaust fan 245 (FAN3), the LED boards 240Ra, 240Ga, 240Ba, and the DMD board 241a (not shown). The power supply circuit B20 is also included.

  The first temperature sensor B25a and the second temperature sensor B25b perform the same function as the above-described temperature sensor B25. The first temperature sensor B25a is provided to detect a temperature near the LED light source 240R in the LED board 240Ra and output a temperature detection signal to the projector control board B23. The second temperature sensor B25b is provided to detect a temperature near the LED light source 240G or the LED light source 240B in the LED board 240Ga or the LED board 240Ba, and output a temperature detection signal to the projector control board B23. As described above, regarding the heat generation characteristics of the LED light sources 240R, 240G, and 240B, the LED light sources 240G and 240B tend to be relatively high, while the LED light source 240R tends to be relatively low. Specifically, the temperature detected by the second temperature sensor B25b tends to be higher than the temperature detected by the first temperature sensor B25a. It should be noted that only one of the temperature sensors B25a and B25b of this type may be provided according to the specifications. When the first temperature sensor B25a and the second temperature sensor B25b are not particularly distinguished, they are referred to as a temperature sensor B25.

  The intake air temperature sensor B26a is arranged near the intake port of the intake fan 244B (FAN2), detects the temperature of air supplied from outside to inside of the projector B2 through the intake fan 244B, and controls the projector. It is provided so as to output a temperature detection signal to the substrate B23. The exhaust temperature sensor B26b is disposed near the exhaust port of the exhaust fan 245 (FAN3), detects the temperature of the air exhausted from the inside of the projector device B2 to the outside through the exhaust fan 245, and controls the projector control. It is provided so as to output a temperature detection signal to the substrate B23. Generally, the temperature detected by the exhaust temperature sensor B26b tends to be higher than the temperature detected by the intake temperature sensor B26a. Note that only one of the temperature sensors B26a and B26b of this type may be provided according to the specifications. Further, the intake air temperature sensor B26a and the exhaust air temperature sensor B26b may be referred to as ventilation temperature sensors.

  The pulse sensor B27a is provided to output a pulse signal corresponding to the rotation speed of the intake fan 244A (FAN1) to the projector control board B23 as a rotation speed detection signal of FAN1. The pulse sensor B27b is provided to output a pulse signal corresponding to the rotation speed of the intake fan 244B (FAN2) to the projector control board B23 as a rotation speed detection signal of FAN2. The pulse sensor B27c is provided to output a pulse signal corresponding to the rotation speed of the exhaust fan 245 (FAN3) to the projector control board B23 as a rotation speed detection signal of the FAN3. In this embodiment, a relatively high rotation type is used for the intake fans 244A and 244B (FAN1 and FAN2), and a relatively low rotation type is used for the exhaust fan 245 (FAN3). As a result, the rotational speed detected via the pulse sensors B27a and B27b corresponding to FAN1 and FAN2 tends to be higher than the rotational speed detected via the pulse sensor B27c corresponding to FAN3. It should be noted that only one or two of these types of pulse sensors 27a, 27b, and 27c may be provided depending on the specifications. The pulse sensor may be configured by, for example, a photo interrupter.

  The fourth to twenty-third modifications will be described below on the premise of the projector apparatus B2 as described above. In addition, each of the following modified examples does not necessarily use all of the temperature sensors and the pulse sensors, but can be realized using only some of them. In addition, as for each of the following modified examples, arbitrary modified examples can be appropriately combined with each other as long as there is no special reason that makes the combination difficult such as a failure of technical prerequisites.

  FIG. 129 shows a projector control main process by the control LSI 230 of the projector control board B23 as a process according to the fourth modification. The processing shown in FIG. 129 is obtained by improving a part of the processing shown in FIG. 107 described above so as to be suitable for the projector B2 in FIG.

  As shown in FIG. 129, when the power is turned on, the control LSI 230 performs a projector initialization process (S1001). This processing corresponds to the processing in FIG.

  Next, the control LSI 230 determines whether or not the reception completion flag in the various flags & work area of the DRAM is "ON" (S1002). When the reception completion flag is “ON” (S1002: Yes), the control LSI 230 proceeds to the next processing of S1003. If the reception completion flag is not “ON” (S1002: No), the control LSI 230 proceeds to the process of S107.

  Next, the control LSI 230 acquires the reception data from the reception storage area of the DRAM (S1003).

  Next, the control LSI 230 sets the reception completion flag in the various flags & work area of the DRAM to “OFF” (S1004).

  Next, the control LSI 230 determines whether or not the transmission destination ID of the acquired reception data indicates "projector" (S1005). When the transmission destination ID indicates “projector” (S1005: Yes), the control LSI 230 proceeds to the next process of S1006. If the transmission destination ID does not indicate “projector” (S1005: No), the control LSI 230 proceeds to the process of S1007.

  Next, the control LSI 230 performs processing at the time of reception between the sub control and the projector (S1006). This processing corresponds to the processing in FIG.

  Next, the control LSI 230 performs a projector self-diagnosis process (S1007). This processing corresponds to the processing in FIG. It should be noted that the projector self-diagnosis processing can be applied as processing as shown in FIG.

  Next, the control LSI 230 performs processing at the time of transmission between the sub control and the projector (S1008). This processing corresponds to the processing in FIG. The processing at the time of transmission between the sub-control and the projector can also be applied as processing as shown in FIG. 135 described later.

  Next, the control LSI 230 determines whether an LED temperature abnormality (shutdown), a fan rotation abnormality, a fan temperature abnormality, or a voltage abnormality is written in the error management area of the DRAM (S1009). The LED temperature abnormality (shutdown) means an LED temperature abnormality that leads to a forced shutdown to be described later. Generated and stored when detected as temperature or higher. The FAN rotation abnormality means a FAN rotation abnormality that leads to a forced shutdown, and using the FAN temperature rotation number control table shown in FIG. Generated and stored when detected. The FAN temperature abnormality is generated and stored when the intake air temperature near FAN2 is detected as a predetermined temperature or higher using the FAN temperature control table shown in FIG. The voltage abnormality is generated and stored, for example, when a voltage boost of less than a predetermined specified voltage value is detected in the power supplied from the power supply circuit B20. If any of these abnormalities has been written to the error management area (S1009: Yes), the control LSI 230 basically transmits an error notification command to the sub CPU 400 of the sub control board SS. Move on to processing. The error notification will be described later. On the other hand, if none of the abnormalities has been written to the error management area (S1009: No), the control LSI 230 proceeds to the process of S1013. As the FAN temperature control table, a table shown in FIG. 132 described later can be applied instead of the table shown in FIG. 131 (b). Further, a FAN temperature rotation speed control table as shown in FIG. 134 described later can be applied.

  Next, the control LSI 230 determines whether or not the sub CPU 400 of the sub control board SS has responded, for example, by returning a status request command in response to the error notification command transmission (S1010). If the sub CPU 400 has responded (S1010: Yes), the control LSI 230 proceeds to the process of S1012. If the sub CPU 400 has not responded (S1010: No), the control LSI 230 proceeds to the process of S1011.

  Next, the control LSI 230 determines whether a predetermined time (for example, 30 seconds) has elapsed after confirming that any abnormality is written in the error management area of the DRAM (S1011). If the predetermined time has elapsed (S1011: Yes), the control LSI 230 proceeds to the process of S1012. If the predetermined time has not elapsed (S1011: No), the control LSI 230 proceeds to the process of S1013.

  Next, the control LSI 230 sends a rotation stop command to the FANs 1 to 3 and a drive stop command to the DLP control circuit 232 and the LED driver 233 that drives the LED light sources 240R, 240G, and 240B (S1012). Thereby, the main operation of the projector device B2 is forcibly shut down.

  Next, the control LSI 230 determines whether the reset request flag in the various flags & work area of the DRAM is "ON" (S1013). If the reset request flag is “ON” (S1013: Yes), the control LSI 230 proceeds to the next process of S1014. When the reset request flag is not “ON” (S1013: No), the control LSI 230 proceeds to the process of S1015.

  Next, the control LSI 230 waits for a reset of the watchdog timer (WDT) (S1014). Waiting for the reset of the watchdog timer is a process of performing an infinite loop process without clearing (or setting a predetermined value of) the watchdog timer and waiting for the watchdog timer to output a reset signal to the control LSI 230. When the timer outputs a reset signal to the control LSI 230, the control LSI 230 is reset, so that the process is restarted from the first step (S1001) in the projector control main process (also called “reboot”).

  In S1015, the control LSI 230 clears the value of the watchdog timer (WDT).

  Next, the control LSI 230 waits for a period of, for example, 4 msec (S1016). After that, the control LSI 230 proceeds to the process of S1002.

  FIG. 130 shows a self-diagnosis process by the control LSI 230 of the projector control board B23 as a process according to the fourth modification. The processing shown in FIG. 130 is obtained by improving a part of the processing shown in FIG. 113 described above so that the processing is suitable for the projector apparatus B2 in FIG. 128 in conjunction with the projector control main processing in FIG.

  As shown in FIG. 130, the control LSI 230 writes, for example, '55AAH' as a diagnostic value read from the ROM in the self-diagnosis storage area of the DRAM by a verify check (S1021).

  Next, the control LSI 230 determines whether or not the value (load value) read from the self-diagnosis storage area correctly matches the diagnosis value (S1022). When the load value matches the diagnosis value (S1022: Yes), the control LSI 230 proceeds to the process of S1024. If the load value does not match the diagnostic value (S1022: No), the control LSI 230 proceeds to the next step S1023.

  Next, the control LSI 230 sets "self-diagnosis abnormality" as error data in the error management area of the DRAM (S1023). This self-diagnosis abnormality includes an error due to a watchdog timer (WDT) reset wait described later. When the error information relating to the self-diagnosis abnormality including the waiting for the WDT reset is set, the control LSI 230 transmits the command indicating the error notification to the transmission data in the sub control-projector transmission process (S1008) shown in FIG. (See S817 in FIG. 135 described later), set the reset request flag to 'ON' (see S818 and S819 'in FIG. 135 described later), and described above according to the reset signal from the watchdog timer. The projector initialization processing (S1001) shown in FIG. 129 is executed. The sub-control-to-projector transmission process and the projector initialization process executed in this case will be described later with reference to FIGS. 135 and 136.

  Next, the control LSI 230 performs an LED temperature diagnosis process (S1024). In this process, the control LSI 230 acquires the LED temperature based on the temperature detection signals from the first temperature sensor B25a and the second temperature sensor B25b.

  Next, the control LSI 230 determines whether or not the acquired LED temperature is normal (S1025). If the acquired LED temperature is normal (S1025: Yes), the control LSI 230 proceeds to the process of S1027. If the acquired LED temperature is not normal (S1025: No), the control LSI 230 proceeds to the next step S1026.

  Next, the control LSI 230 sets “LED temperature abnormal” as error data in the error management area of the DRAM (S1026). Specifically, the first temperature sensor B25a and the second temperature sensor B25b detect temperatures near the LED light sources 240R, 240G, and 240B. The control LSI 230 measures each temperature through the first temperature sensor B25a and the second temperature sensor B25b to determine whether the measured temperature is equal to or higher than a predetermined temperature based on the LED temperature control table in FIG. If the temperature is equal to or higher than the predetermined temperature, error information indicating an abnormality related to a warning or forced shutdown is set in the error management area of the DRAM. The warning means a warning displayed before the forced shutdown is performed. The forced shutdown indicates that the main operations of the LED light sources 240R, 240G, 240B, and FAN1 to 3 of the projector apparatus B2 are abnormal such as temperature and FAN rotation speed. Means to forcibly stop according to.

  For example, as the error information of the LED (R) temperature abnormality relating to the LED light source 240R, a warning is set when the temperature near the LED light source 240R detected by the first temperature sensor B25a is 85 ° C. or more and less than 90 ° C. , 90 ° C. or higher, a forced shutdown is set. The error information of the LED (G) temperature abnormality relating to the LED light source 240G and the error information of the LED (B) temperature abnormality relating to the LED light source 240B have different generation conditions from the error information of the LED (R) temperature abnormality. A warning is set when the temperature near the LED light source 240G or near the LED light source 240B detected by the temperature sensor B25b is 100 ° C. or higher and lower than 105 ° C. If the temperature is 105 ° C. or higher, a forced shutdown is set. When such error information relating to the LED temperature abnormality is set, the control LSI 230 creates a command indicating an error notification as transmission data in the sub-control-projector transmission process (S1008) shown in FIG. 135 (see S817 in FIG. 135), the command indicating the error notification is transmitted to the sub CPU 400 of the sub control board SS without setting the reset request flag to 'ON' (see S818 and S819 'in FIG. 135 described later). (See S825 in FIG. 135 described later). The sub-control-to-projector transmission process and projector initialization process executed in this case will also be described later with reference to FIGS. 135 and 136.

  Next, the control LSI 230 performs a fan rotation diagnosis process (S1027). In this process, the control LSI 230 acquires the FAN rotation speed based on the fan rotation speed signals from the pulse sensors B27a to B27c of the FAN1 to FAN3.

  Next, the control LSI 230 determines whether or not the obtained FAN rotation speed is normal (S1028). If the acquired FAN rotation speed is normal (S1028: Yes), the control LSI 230 proceeds to the process of S1030. If the acquired FAN rotation speed is not normal (S1028: No), the control LSI 230 proceeds to the next process of S1029.

  Next, the control LSI 230 sets “FAN rotation abnormality” as error data in the error management area of the DRAM (S1029). Specifically, the pulse sensors B27a to B27c detect the rotation speeds of the fans FAN1 to FAN3. Further, for example, the intake air temperature sensor B26a detects the intake air temperature of the FAN2 as a reference FAN temperature. The control LSI 230 measures each rotation speed through the pulse sensors B27a to B27c, and measures the FAN temperature through the intake air temperature sensor B26a, so that the FAN temperature becomes a predetermined temperature based on the FAN temperature rotation speed control table in FIG. (E.g., 32 [deg.] C.) or less, and if the FAN temperature is equal to or less than a predetermined temperature, one of the rotation speeds of FAN1 to FAN3 is individually set to a predetermined rotation speed (e.g., FAN1: 4410 rpm, FAN2). If the FAN temperature is higher than a predetermined temperature, the error information indicating the abnormality related to the forced shutdown is set in the error management area of the DRAM. The number of rotations is specified individually as more severe conditions than those described above. Specific rotation speed (e.g., FAN1: 6090rpm, FAN2: 4410rpm, FAN3: 4410rpm) is less than, sets an error information to the error management area of the DRAM indicating an abnormality relating to forced shutdown.

  For example, based on the FAN temperature rotation speed control table of FIG. 134, the error information of the rotation speed abnormality related to FAN1 includes the case where the rotation speed detected by the pulse sensor B27a is less than 4410 rpm when the FAN temperature is 32 ° C. or less. , Forced shutdown is set. Further, as the error information of the rotational speed abnormality relating to the FAN1, the forced shutdown is set when the rotational speed detected by the pulse sensor B27a is less than 6090 rpm when the FAN temperature is higher than 32 ° C. Based on the FAN temperature / rotation speed control table shown in FIG. 134, the forced shutdown is set for the error information of the rotation speed abnormality related to FAN2 and FAN3 when the same condition is satisfied. When the error information relating to the FAN rotation speed abnormality is set, the control LSI 230 creates a command indicating an error notification as transmission data in the sub-control-projector transmission process (S1008) shown in FIG. The command indicating the error notification is transmitted to the sub CPU 400 of the sub control board SS without setting the reset request flag to 'ON' (see S 817 and S 819 of FIG. 135 described later) without setting the reset request flag to 'ON' (see S 817 of FIG. 135 described later). (See S825 in FIG. 135 described later). The sub-control-to-projector transmission process and projector initialization process executed in this case will also be described later with reference to FIGS. 135 and 136.

  Next, the control LSI 230 performs a FAN temperature diagnosis process (S1030). In this process, the control LSI 230 acquires the intake air temperature as the FAN temperature based on, for example, a temperature detection signal from the intake air temperature sensor B26a.

  Next, the control LSI 230 determines whether or not the acquired FAN temperature is normal (S1031). If the acquired FAN temperature is normal (S1031: Yes), the control LSI 230 proceeds to the process of S1033. When the acquired FAN temperature is not normal (S1031: No), the control LSI 230 shifts to the next processing of S1032. Note that, for example, a temperature sensor may be installed in each of the FANs 1 to 3, and the FAN rotation speed may be controlled in accordance with the FAN temperatures 1 to 3 detected by the respective temperature sensors.

  Next, the control LSI 230 sets “FAN temperature abnormality” as error data in the error management area of the DRAM (S1032). Specifically, the intake air temperature sensor B26a detects a FAN temperature (intake air temperature) near FAN2. The control LSI 230 determines whether or not the FAN temperature is equal to or higher than the predetermined temperature based on the FAN temperature control table of FIG. 131B by measuring the FAN temperature through the intake air temperature sensor B26a. For example, error information indicating an abnormality related to the forced shutdown is set in an error management area of the DRAM. For example, as the error information of the abnormal fan temperature, if the fan temperature detected by the intake air temperature sensor B26a is equal to or higher than 67 ° C., the forced shutdown is set. When the error information relating to the FAN temperature abnormality is set, the control LSI 230 creates a command indicating an error notification as transmission data in the sub-control-projector transmission process (S1008) shown in FIG. 135 (see S817 in FIG. 135), the command indicating the error notification is transmitted to the sub CPU 400 of the sub control board SS without setting the reset request flag to 'ON' (see S818 and S819 'in FIG. 135 described later). (See S825 in FIG. 135 described later). The sub-control-to-projector transmission process and projector initialization process executed in this case will also be described later with reference to FIGS. 135 and 136.

  Next, the control LSI 230 performs a projector power supply diagnosis process (S1033). In this process, the control LSI 230 detects the operating voltage of the power supplied from the power supply circuit B20 of the projector device B2.

  Next, the control LSI 230 determines whether the operating voltage of the projector B2 is equal to or higher than a specified voltage (S1034). When the operating voltage of the projector B2 is equal to or higher than the specified voltage (S1034: Yes), the control LSI 230 proceeds to the process of S1036. When the operating voltage of the projector device B2 is lower than the specified voltage (S1034: No), the control LSI 230 proceeds to the next process of S1035.

  Next, the control LSI 230 sets "voltage abnormality" as error data in the error management area of the DRAM (S1035). Specifically, for example, error information of voltage abnormality indicating an abnormal voltage drop is set. When the error information relating to such a voltage abnormality is set, the control LSI 230 creates a command indicating an error notification as transmission data in the sub-control-projector transmission process (S1008) shown in FIG. 129 described above (described later). The command indicating the error notification is transmitted to the sub CPU 400 of the sub control board SS without setting the reset request flag to “ON” (see S818 and S819 of FIG. 135 described later) without setting the reset request flag to “ON” (see S817 in FIG. 135). (See S825 in FIG. 135 described later.) The sub-control-to-projector transmission process and projector initialization process executed in this case will also be described later with reference to FIGS. 135 and 136.

  Next, the control LSI 230 performs a DLP operation diagnosis process (S1036). In this processing, the control LSI 230 checks the operation of the DLP control circuit 232.

  Next, the control LSI 230 determines whether or not the operation of the DLP control circuit 232 is normal (S1037). When the operation of the DLP control circuit 232 is normal (S1037: Yes), the control LSI 230 ends the projector self-diagnosis processing. If the operation of the DLP control circuit 232 is not normal (S1037: No), the control LSI 230 proceeds to the next process of S1038.

  Next, the control LSI 230 sets “DLP abnormal” as error data in the error management area of the DRAM (S1038). When such error information relating to the DLP abnormality is set, the control LSI 230 creates a command indicating an error notification as transmission data in the sub-control-projector transmission process (S1008) shown in FIG. 129 described above (described later). After setting the reset request flag to “ON” (see S817 in FIG. 135) (refer to S818 and S819 ′ in FIG. 135 described later), the projector initial state shown in FIG. 129 described above according to the reset signal from the watchdog timer. A conversion process (S1001) is executed. That is, since a command indicating an error notification is created as transmission data in S1008 and the reset request flag is set to “ON”, the error notification command created in S1008 is not processed in S727 ′ of FIG. 136 after reboot. Will be sent. At this time, an error notification command or information indicating the error notification may be stored in the EEPROM 231. In such a case, even if a voltage change (abnormality due to drop, disconnection, increase, etc.) occurs due to power interruption or restart, commands and information can be retained without being erased. The sub-control-to-projector transmission process and projector initialization process executed in this case will also be described later with reference to FIGS. 135 and 136. After that, the control LSI 230 ends the projector self-diagnosis processing.

  According to such projector control main processing and projector self-diagnosis processing, an error notification command is transmitted to the sub-control board SS in response to various abnormalities of the projector device B2, and at this time, a response from the sub-control board SS is received. In this case, since the operation of the projector device B2 is forcibly shut down, it is possible to avoid a malfunction due to the heat accumulation of the projector device B2, and to eliminate the discomfort of the image over a long time.

  Further, even if there is no response from the sub-control board SS, the operation of the projector device B2 is automatically shut down after a predetermined time, for example, 30 seconds, so that the malfunction of the projector device B2 is reliably avoided. Can be. In the case of DLP abnormality, that is, in the case of error processing by the watchdog timer, a reboot (initialization processing) is performed, and error transmission is performed after the reboot. In the case of this type of DLP abnormality, there is a high possibility that the projector device B2 is frozen, and it is difficult to notify the sub CPU 400 of the sub control board SS of an error (for example, if the communication status is Commands and information to be created cannot be created normally). Therefore, the error transmission is performed after the reboot. It should be noted that the DLP abnormality may be handled in the same manner as other errors, and the error transmission related to the DLP abnormality may be performed before the reboot. When the projector device B2 itself reboots or shuts down, communication with the sub CPU 400 is not performed for a predetermined time (for example, 1000 ms) or more, so that the sub CPU 400 detects an abnormality, and the sub CPU 400 A reboot instruction (or restart) may be issued to the device B2. If the sub CPU 400 has not received the signal from the projector device B2 for a predetermined time (for example, 1000 ms) or more, it is determined that the possibility that the projector device B2 is executing the reboot process is high, and the sub CPU 400 transmits the signal after the reboot process. When the sub CPU 400 cannot receive the error notification command received (ie, when a time longer than 1000 ms, for example, 5000 ms has elapsed), the sub CPU 400 controls the projector device B2 to forcibly reboot. Alternatively, notification of an error may be performed.

  FIG. 131 shows an LED temperature control table and a FAN temperature control table stored in the EEPROM 231 of the projector control board B23 as reference tables according to the fourth modification.

  As shown in FIG. 131 (a), in the LED temperature control table, the control condition corresponding to the temperature abnormality of the LED light source 240R (LED (R)), the LED light source 240G (LED (G)) and the LED light source 240B ( The control condition corresponding to the temperature abnormality of the LED (B) is defined to be different.

  For example, the operation of the LED light source 240R (LED (R)) is normally controlled when the LED temperature is 0 ° C or higher and lower than 85 ° C, and the operation is controlled without stopping when the LED temperature is 85 ° C or higher and lower than 90 ° C. However, it is controlled so that a warning (warning display) is generated as a temperature abnormality based on a projection image on a screen or a display image of the sub liquid crystal display device DD19, and when the LED temperature becomes 90 ° C. or more, the projector device B2 is activated. The main operation is controlled to forcibly shut down. At the time of the warning, a process corresponding to the warning is performed by the control LSI 230, a command related to an error warning is transmitted to the sub CPU 400 of the sub control board SS, and the projection image indicating the warning is displayed on the screen in the projector device B2. On the other hand, on the sub liquid crystal display device DD19, an image indicating the shutdown of the projector device B2 is displayed. At the time of the forced shutdown, since a command related to the error notification is transmitted to the sub CPU 400 of the sub control board SS, an image indicating the shutdown of the projector device B2 is displayed on the sub liquid crystal display device DD19.

  On the other hand, the operation of the LED light sources 240G (LED (G)) and the LED light sources 240B (LED (B)) is normally controlled if the LED temperature is 0 ° C. or more and less than 100 ° C. If the temperature is lower than 0 ° C., the operation is controlled without stopping, but a warning (warning display) is performed as a temperature abnormality based on a projection image on the screen or a display image of the sub liquid crystal display device DD19. When the temperature reaches 105 ° C. or higher, the main operation of the projector device B2 is controlled to be forcibly shut down. Even in the case of such a warning, the control LSI 230 performs a process corresponding to the warning, a command related to an error warning is transmitted to the sub CPU 400 of the sub control board SS, and a warning is displayed on the screen in the projector device B2. While the projection video is displayed, an image indicating the shutdown of the projector device B2 is displayed on the sub liquid crystal display device DD19. Also, at the time of the forced shutdown, since a command related to the error notification is transmitted to the sub CPU 400 of the sub control board SS, an image indicating the shutdown of the projector device B2 is displayed on the sub liquid crystal display device DD19. The image indicating the warning or the shutdown is projected by the projector device B2, and is also displayed on the liquid crystal display device DD19 in the same manner as the projected image. Thereby, even when the projection by the projector device B2 is difficult or impossible, or when the display by the liquid crystal display device DD19 is difficult or impossible, an image indicating a warning or a shutdown is displayed by one of the display units. It is possible to reliably notify the player or the game arcade manager of the fact. At this time, in addition to the projection by the projector device B2 and the display by the liquid crystal display device DD19, the occurrence of an error from the external centralized terminal board 31 of the gaming machine 1 to the management device of the game arcade such as a hall computer or an island control computer. It may be notified and notified. The display means of the present embodiment includes a projection device, a screen, a liquid crystal display device, a display device with lighting in units of dots using LEDs, a touch panel, a flexible liquid crystal display device, an illuminator (registered trademark), a transparent liquid crystal display, and the like. A display, a transparent screen, a movable accessory, a non-movable accessory, and the like can be applied. Further, the number of projector devices, screens, and liquid crystal display devices is not particularly limited. In the gaming machine 1 of the present embodiment, the security signal is externally output from the main control board MS and the payout / emission control circuit (not shown) via the external centralized terminal board 31, but is output from the sub CPU 400 of the sub control board SS. The security signal may be externally output.

  Further, as shown in FIG. 131 (b), in the FAN temperature control table, a control condition corresponding to the FAN temperature is basically defined for the FAN temperature (intake air temperature) of the FAN2.

  For example, if the FAN temperature is 0 ° C. or more and less than 67 ° C., the operation is normally controlled. If the FAN temperature becomes 67 ° C. or more, the main operation of the projector B2 is forcibly shut down without performing a warning (warning display). Is controlled. At the time of such a forced shutdown due to the FAN temperature, a command related to an error notification is transmitted to the sub CPU 400 of the sub control board SS, so that an image indicating the shutdown of the projector device B2 is displayed on the sub liquid crystal display device DD19. Is done. Also in this case, the image indicating the warning or the shutdown is projected by the projector device B2 and displayed on the liquid crystal display device DD19 in the same manner as the projected image. Thereby, even when the projection by the projector device B2 is difficult or impossible, or when the display by the liquid crystal display device DD19 is difficult or impossible, an image indicating a warning or a shutdown is displayed by one of the display units. It is possible to reliably notify the player or the game arcade manager of the fact. In addition to the projection by the projector device B2 and the display by the liquid crystal display device DD19, the occurrence of an error is communicated from the external centralized terminal board 31 of the gaming machine 1 to a management apparatus of a game arcade such as a hall computer or an island computer. The notification may be made.

  According to the LED temperature control table and the FAN temperature control table, the LED temperatures of the LED light sources 240R (LED (R)), the LED light sources 240G (LED (G)), and the LED light sources 240B (LED (B)) are determined. When the temperature rises and exceeds a specified temperature (for example, LED (R): 85 ° C., LED (G), (B): 100 ° C.), it is determined that there is an abnormality, and a warning is issued, and the LED temperature further rises And the temperature becomes higher than a specified temperature (eg, LED (R): 90 ° C., LED (G), (B): 105 ° C.), or even if the intake air temperature (FAN temperature) near FAN2 is lower than the LED temperature. (For example, 67 ° C.) or more, the main operation of the projector B2 is temporarily stopped by the forced shutdown. The malfunction appropriately avoided on which made known a priori by the warning, it is possible to eliminate the discomfort of the image, such as up to long.

  Further, according to the LED temperature control table and the FAN temperature control table, when the temperature of the LED (R) becomes 85 ° C. or more, for example, or when the temperature of the LEDs (G) and (B) becomes higher, for example, 100 ° C. or more, An error warning is issued to the CPU 400, and the temperature of the LED (R) rises to, for example, 90 ° C. or more, or the temperature of the LEDs (G), (B) rises to, for example, 105 ° C. or more, or When the intake air temperature of the fan 2 is lower than the temperature (85 ° C.) at which a warning (error warning) of the LED (R) is performed and becomes equal to or higher than the specified temperature of the fan 2, for example, 67 ° C., the operation of the projector apparatus B2 is started. Is temporarily stopped by the forced shutdown, and the malfunction due to the heat accumulation of the projector apparatus B2 is notified in advance by a warning to the sub CPU 400. Appropriately avoided on which made known, it is possible to eliminate the discomfort of the image, such as up to long. Note that the temperature (85 ° C.) at which the warning of the LED (R) is performed is not limited to the LED (R), but is a temperature used as a criterion for determining whether an abnormality has occurred in the entire LED including the LED (G) and the LED (B). It may be. That is, when there are a plurality of types of LEDs such as the LED (R), the LED (G), and the LED (B), the presence or absence of an abnormality may be determined based on any one of the LED temperatures. The intake air temperature of the fan 2 is a temperature that can be recognized as a temperature around the intake fan, a temperature of the intake fan itself, an external temperature of the projector device, an outside air temperature, or the like.

  According to the LED temperature control table and the FAN temperature control table, for example, when the temperature of the LED (R) becomes 85 ° C. or higher, a warning is issued to the sub CPU 400, and a warning related to error notification is displayed on the screen accordingly. Is displayed on the sub liquid crystal display device DD19, and an image indicating a warning related to the same error notification is separately displayed. Further, when the temperature of the LED (R) rises to, for example, 90 ° C. or more, or when the intake air temperature of the FAN 2 becomes, for example, 67 ° C. or more, an error notification is sent to the sub CPU 400, and a warning is accordingly issued. After an image relating to a different error notification is displayed on the sub liquid crystal display device DD19, the operation of the projector device B2 is forcibly stopped by a response from the sub CPU 400 to the error notification. Thereby, the malfunction due to the heat accumulation of the projector device B2 is notified in advance by an error notification related to a warning and an error notification related to a forced shutdown after that, and is appropriately avoided. Can be eliminated. In this case, if there is no response from the sub CPU 400 within a predetermined time (for example, 30 s), the shutdown can be forcibly performed.

  FIG. 132 shows a FAN temperature control table stored in the EEPROM 231 of the projector control board B23 as a table according to the fifth modification. The table shown in FIG. 132 is obtained by improving the FAN temperature control table shown in FIG. 131 (b).

  In the FAN temperature control table shown in FIG. 132, it is defined that the control condition corresponding to the intake air temperature (FAN2) temperature abnormality and the control condition corresponding to the exhaust gas temperature (FAN3) temperature abnormality are different.

  For example, the intake air temperature is controlled so as to forcibly shut down the main operation of the projector apparatus B2 when the intake air temperature reaches 67 ° C. or higher, as in the case shown in FIG. At the time of the forced shutdown, an image indicating the shutdown of the projector B2 is displayed on the sub liquid crystal display device DD19. On the other hand, as for the exhaust temperature, the operation is normally controlled until the temperature reaches, for example, 75 ° C., which is somewhat higher than the case of the intake temperature, and the operation is controlled without stopping at 75 ° C. or more and less than 80 ° C. A warning (warning display) is performed as a temperature abnormality based on the projection image and the display image of the sub liquid crystal display device DD19, and further, when the exhaust temperature exceeds 80 ° C., the main operation of the projector device B2 is forcibly shut down. Controlled. Even in the case of such a warning, the control LSI 230 performs a process corresponding to the warning, a command related to an error warning is transmitted to the sub CPU 400 of the sub control board SS, and a warning is displayed on the screen in the projector device B2. While the projection video is displayed, an image indicating the shutdown of the projector device B2 is displayed on the sub liquid crystal display device DD19. Also, at the time of the forced shutdown, since a command related to the error notification is transmitted to the sub CPU 400 of the sub control board SS, an image indicating the shutdown of the projector device B2 is displayed on the sub liquid crystal display device DD19.

  FIG. 133 illustrates a process at the time of receiving a projector error notification by the sub CPU 400 of the sub control board SS, as a process according to the sixth modification. The processing shown in FIG. 133 is obtained by improving a part of the processing shown in FIG. 93 described above so as to be suitable for the projector B2 in FIG.

  As shown in FIG. 133, the sub CPU 400 performs a process when a projector error occurs in response to an error notification from the projector control board B23 (S1041).

  Next, if the projector error is a warning, the sub CPU 400 sends a display request to both the sub liquid crystal display device DD19 and the projector device B2 so as to make a notification related to the warning while making full use of both, and sends a request to the projector device B2. A response signal (command) corresponding to the error notification is transmitted (S1042). If the projector error is not a warning, the sub CPU 400 skips the process of S1042 and proceeds to the next process of S1043.

  Next, if the projector error is a shutdown, the sub CPU 400 issues a display request to the sub liquid crystal display device DD19 so that the sub liquid crystal display device DD19 notifies the shutdown of the projector device B2. When the notification regarding the shutdown is performed in the display device DD19, a response signal (command) corresponding to the error notification is transmitted to the projector device B2 thereafter (S1043).

  Next, the sub CPU 400 issues a sound projector error occurrence output request to the speaker group 62 to notify an error of the projector control board B23 (projector device B2) by sound (S1044). Thereafter, sub CPU 400 ends the process at the time of receiving the projector error notification.

  By using the FAN temperature control table of FIG. 132 in combination with the LED temperature control table of FIG. 131 (a) and executing the projector error notification receiving process of FIG. 133, for example, When the temperature is 85 ° C. or higher, or when the exhaust temperature of the fan 3 becomes lower than that temperature, for example, 75 ° C. or higher, an error is notified to the sub CPU 400 by determining that the temperature is abnormal, and the LED (R) When the temperature rises to, for example, 90 ° C. or higher, or when the intake temperature of the FAN 2 becomes 67 ° C. or higher, which is lower than the case of the exhaust temperature, the operation of the projector device B2 is automatically stopped by the forced shutdown. The operation failure due to the heat accumulation of the projector device B2 is notified in advance by a warning to the sub CPU 400. Appropriately avoided, it is possible to eliminate the discomfort of the image, such as up to long.

  FIG. 134 shows a FAN temperature / rotation speed control table stored in the EEPROM 231 of the projector control board B23 as a table according to the seventh modification.

  As shown in FIG. 134, in the FAN temperature rotation speed control table, the control conditions for the shutdown are different based on the lower limit of the FAN rotation speed defined for each of the FANs 1 to 3. As the FAN temperature, for example, the intake air temperature of FAN2 is applied.

  For example, when the FAN temperature (FAN2) is 32 ° C. or lower, if the FAN rotation speed of the intake FAN1 becomes lower than 4410 rpm defined as a lower limit value, it is determined that a rotation speed error occurs due to insufficient intake capacity, and the intake fan For FAN2, when the FAN rotation speed falls below 4410 rpm defined as a lower limit value, it is determined that a rotation speed error has occurred due to insufficient intake capacity, and for FAN3 for exhaust, the FAN rotation speed is less than 3710 rpm defined as a lower limit value. , A rotational speed error is determined due to insufficient intake capacity. When the rotation speed error is determined in this way, the main operation of the projector device B2 is controlled to forcibly shut down.

  On the other hand, when the FAN temperature (FAN2) is higher than 32 ° C., it is required to exhibit a larger intake / exhaust (ventilation) capacity. Therefore, when the FAN temperature (FAN2) becomes higher than 32 ° C., the lower limit of some FAN rotation speeds is increased. Accordingly, when the FAN temperature (FAN2) is higher than 32 ° C., if the FAN rotation speed of the intake FAN1 becomes lower than the above lower limit value of 6090 rpm, a rotation speed error is determined due to insufficient intake capacity. When the FAN rotation speed for the intake FAN2 becomes less than 4410 rpm defined as the same lower limit as above, a rotation speed error is determined due to insufficient intake capacity, and for the exhaust FAN3, the FAN rotation speed is set to the above value. If it becomes less than 4410 rpm defined as a higher lower limit, it is determined that a rotational speed error has occurred due to insufficient intake capacity. In this way, even when the rotation speed error is determined, the main operation of the projector device B2 is controlled to be forcibly shut down.

  According to such a FAN temperature rotation speed control table, when the FAN temperature becomes higher than, for example, 32 ° C., the operation of the projector apparatus B2 is stopped by the forced shutdown. Accordingly, for the fan FAN 3 for exhaust and the fan FAN 1 for intake, the operation of the projector device B2 is stopped by forced shutdown in accordance with the respective FAN rotation speeds. Further, when the FAN temperature is 32 ° C. or lower, the operation of the projector device B2 is stopped by the forced shutdown according to the FAN rotation speed of the intake FAN 2 corresponding to the FAN temperature regardless of the temperature. It is possible to appropriately avoid the operation failure due to the accumulation according to the FAN temperature and the FAN rotation speed, and to solve the discomfort of the image which is prolonged for a long time.

  Further, according to the FAN temperature rotation speed control table, the operation of the projector apparatus B2 is stopped by the forced shutdown according to the FAN temperature and the FAN rotation speed of the exhaust fan FAN3, while the operation for the intake air is stopped regardless of the detected FAN temperature. The operation of the projector apparatus B2 is stopped by the forced shutdown even according to the FAN rotation speed of the FAN2, so that the operation failure due to the heat accumulation of the projector apparatus B2 can be appropriately avoided according to the FAN temperature and the FAN rotation speed, and the operation can be performed for a long time. It is possible to eliminate the discomfort of the image that extends.

  Further, according to the FAN temperature rotation speed control table, the operation of the projector apparatus B2 is stopped by the forced shutdown in accordance with the FAN temperature of the intake fan FAN2 and the FAN rotation speed of the exhaust fan FAN3 and the intake fan FAN1. Therefore, it is possible to appropriately avoid the malfunction due to the heat accumulation of the projector device B2 in accordance with the FAN temperature and the FAN rotation speed, and to eliminate the discomfort of the image over a long time.

  It should be noted that all of the FANs 1 to 3 are provided with temperature sensors, respectively, and the FANs of the FANs 1 to 3 are set in accordance with the temperature of the airflow passing through each of the FANs 1 to 3 detected via the respective temperature sensors. Stop control based on the rotation speed or shutdown may be performed.

  FIG. 135 shows a process at the time of transmission between the sub control and the projector by the control LSI 230 of the projector control board B23 as the process according to the eighth modification. The processing shown in FIG. 135 is executed in S1008 in the projector control main processing in FIG. 129 described above, and is a partial improvement of only the processing in S819 shown in FIG. 114 described above. Therefore, in FIG. 135, processes other than S819 'are denoted by the same reference numerals, and description thereof will be omitted. Only the process of S819' will be described.

  As shown in FIG. 135, in S819 ', the control LSI 230 sets the reset request flag in the various flags & work area of the DRAM to "ON". After that, the control LSI 230 ends the processing at the time of transmission between the sub-control and the projector. That is, in the case of a self-diagnosis error or a DLP error including an error due to a wait for a reset of the watchdog timer (WDT), an “error notification” command indicating these errors is not immediately transmitted, and the reset request flag is turned on. Waiting for a reset signal to be output from the watchdog timer (WDT) in response to ', and when the reset signal is output, the following projector initialization processing shown in FIG. 136 is executed by a reboot (restart). Becomes

  FIG. 136 shows a projector initialization process by the control LSI 230 of the projector control board B23 as a process according to the eighth modification. The processing shown in FIG. 136 is executed in S1001 in the projector control main processing of FIG. 129 described above, and is a partially improved processing of S727 shown in FIG. 109 described above. Therefore, in FIG. 136, processes other than S727 'are denoted by the same reference numerals, and description thereof will be omitted. Only the process of S319' will be described.

  As shown in FIG. 136, in S727 ′, the control LSI 230 initializes various flags and work areas of the DRAM, and executes a self-diagnosis abnormality (watchdog timer (WDT) If an error notification command indicating a DLP abnormality has been created, the command of the error notification is transmitted to the sub CPU 400 of the sub control board SS. Thereafter, the control LSI 230 ends the projector initialization processing.

  According to the projector control main process and the projector self-diagnosis process shown in FIGS. 129 and 130, and the sub-control-to-projector transmission process and the projector initialization process shown in FIGS. 135 and 136, the LED of the projector device B2 ( R, G, B), FANs 1 to 3 or the power supply circuit B20, even if an abnormality occurs due to a thermal factor, the operation of the projector apparatus B2 is forcibly shut down after an error notification is given to the sub CPU 400 accordingly. Is stopped. On the other hand, for example, when the watchdog timer is not cleared (or a predetermined value is set) and enters an infinite loop and abnormal processing is performed, the operation of the projector apparatus B2 is stopped in this case as well, but the reboot (restart) is performed. When the watchdog timer is reset and the operation of the projector device B2 is restored, an error notification is made to the sub CPU 400, so that various operation failures of the projector device B2 are notified to the sub CPU 400 without fail. Can be avoided.

  As described above, when the abnormal processing is performed using the watchdog timer, the possibility that the projector device B2 is frozen is high, and thus the possibility that the normal operation is guaranteed is low. Reset or restart). At this stage, even if an attempt is made to transmit the transmission command, it is highly likely that the transmission will not be performed normally. Therefore, it is desirable to perform control so that an error notification is sent to the sub CPU 400 after the reboot. As described above, when the projector device B2 is frozen, the watchdog timer is not cleared and the time is up (including the counting of the addition type and the subtraction type). Therefore, the projector device B2 is rebooted and an error occurs after the reboot. Notification will be given. It should be noted that the reboot can be recognized as a process of performing a reboot. Further, when the abnormal processing is performed using the watchdog timer, it is highly likely that the freeze has occurred and the normal projection is difficult, so the liquid crystal display device DD19 and the gaming machine 1 Constituent members (for example, frame constituent members, board constituent members, front door constituent members, cabinets, reels, levers, segment indicators and light sources (mainly, for example, LEDs) of the dispensing control board, and segment indicators provided on the housing) Reflection of projectors and light sources (eg, LEDs), body frame members, dish units, gaming machine side components, buttons, front panels (including liquid product display devices), projector device B2 components, and projector device B2 projection The abnormality may be notified by various constituent members such as a reflective member that is turned on, a decorative member that protrudes from the frame, and the like. According to this, even when various abnormalities are detected, other than when abnormal processing is performed using the watchdog timer, abnormalities are detected by the above-described components of the gaming machine 1 and the projection by the projector device B2. Notification or display (for example, error notification, warning, warning, abnormality notification, etc.) can be performed.

  In addition, regarding the abnormal operation of the gaming machine 1 and the projector device B2, the external communication means of the gaming machine 1 (external centralized terminal board 31, wireless communication means, short-range wireless communication, optical communication means, encryption communication means, decryption communication Means, encryption and decryption communication means, etc.) and external communication means provided in the projector device B2, etc., to playground equipment (for example, a hall computer, an island computer, a sanding device, an outbox, an individual box counting device). Machine, game media lending device with each machine counting machine, data display, digital signage, representative lamp, call button, game media number notification means (for example, the case is driven or emits light to notify the number of game media), Management device, peripheral device, CR unit, etc.) to notify that an error has occurred. As the combined one means, a plurality of means can be used for the gaming machine 1, or any one of the devices can be used, and the gaming machine 1 can be combined in various manners. Can be used to communicate with the outside world. When such an error is notified to the outside, the administrator of the amusement arcade turns on / off the power of the gaming machine 1 (power interruption and recovery from power interruption, or changes in settings), and a setting screen of the gaming machine. An operation for eliminating an error can be performed from a setting screen for a player, a setting screen for a game arcade, and the like. In addition, as the game media, various game media such as medals and balls, and the number of game media on data are assumed. Further, the present invention can also be applied to a gaming machine in which the number of game media on data (holding ball, payout ball, lending ball, ball storage, credit, insertion number, firing number, payout number, foul ball number, etc.) increases or decreases. In addition, possessed ball, payout ball, loaned ball, and accumulated ball are terms applicable to various game media such as medals and balls. In the case of an error in which a reboot is performed in the present embodiment, error information (such as a self-diagnosis abnormality, a DLP abnormality, or a reset request flag) stored before the reboot is performed at the time of reboot is stored (for example, in an EEPROM). Since the data is stored and stored in a storage area that is not cleared before and after the reboot, an error notification can be performed at the time of the initialization processing performed at the time of the restart. After the error notification, various flags and a work area are cleared (one time). Clear all or all of the units, clear only the work area related to the error notification, etc.). It is also possible to determine whether communication between boards or communication between control devices is normally performed using a watchdog timer. In this case, abnormality detection using the watchdog timer can be performed. It can also be described as doing. Further, the error information transmitted to the sub CPU 400 after the reboot of the projector device B2 is transmitted at the time of the power-on or the initialization process executed at the time of the reboot. However, the present invention is not limited to this. Error information may be transmitted in a step after the conversion process.

  FIG. 137 shows a projector control process by the sub CPU 400 of the sub control board SS as a process according to the ninth modification. The process shown in FIG. 137 is obtained by improving a part of the process shown in FIG. 88 described above so as to be suitable for the projector device B2 in FIG.

  As shown in FIG. 137, the sub CPU 400 receives a command indicating that the transmission source ID of the reception data temporarily stored in the sub device reception storage area of the sub RAM board 41 indicates “projector” for a predetermined time (for example, 1000 ms) or more. It is determined whether it has not been performed (S1051). If the command has not been received for a predetermined time or more (S1051: Yes), the sub CPU 400 shifts to the next process of S1052. If any command has been received within the predetermined time (S1051: No), the sub CPU 400 proceeds to the process of S1053. At this time, if the received data is normal, it is transmitted at a period of, for example, 500 ms using the transmission cycle counter. Therefore, the presence or absence of the received data is monitored based on a longer time of 1000 ms. ing.

  Next, the sub CPU 400 outputs a projector error occurrence display request output to the sub liquid crystal I / F substrate SL in order to display an error of the projector control substrate B23 (projector device B2) on the sub liquid crystal display device DD19 (S1052). ). As a result, if there is no response from the projector device B2 even after elapse of, for example, 500 ms or more, an image or the like indicating an error of the projector device B2 is displayed on the sub liquid crystal display device DD19. Thereafter, sub CPU 400 ends the projector control process.

  In S1053, sub CPU 400 determines whether or not the transmission source ID of the reception data temporarily stored in the sub device reception storage area indicates 'projector'. If the transmission source ID indicates “projector” (S1053: Yes), the sub CPU 400 proceeds to the next step S1054. If the transmission source ID does not indicate “projector” (S1053: No), the sub CPU 400 ends the projector control process.

  Next, the sub CPU 400 performs a projector control received data consistency check process for controlling the projector device B2 (S1054). In this processing, the sub CPU 400 checks whether or not the value of the command ID included in the received data matches the values of '81H' to '8BH' indicating the transmission command from the projector control board B23 shown in FIG. And returns the check result as a return value.

  Next, the sub CPU 400 determines whether there is an abnormality in the consistency of the received data from the return value of the check result (S1055). If there is an abnormality in the consistency of the received data (S1055: Yes), the sub CPU 400 proceeds to the next step S1056. When there is no abnormality in the consistency of the received data (S1055: No), the sub CPU 400 shifts to the process of S1057.

  Next, the sub CPU 400 discards the data in the sub device reception storage area (S1056). Thereafter, sub CPU 400 ends the projector control process.

  In S1057, sub CPU 400 performs a process at the time of projector control reception. This processing corresponds to the processing of FIG. 89 described above.

  Next, the sub CPU 400 performs a projector drift correction process (S1058). This processing corresponds to the processing of FIG. 95 described above. Thereafter, sub CPU 400 ends the projector control process.

  According to such a projector control process, when the operation of the projector device B2 should be restored by, for example, a reboot (restart), the sub CPU 400 sets the predetermined time (for example, 500 ms) longer than the transmission time interval (for example, 500 ms) of the projector device B2. For example, if a predetermined response is not received from the projector device B2 even after the elapse of 1000 ms), it is determined that the projector device B2 has some operation failure that cannot be recovered by rebooting, and that fact is determined by an image related to the error notification or the like. It can be displayed on the sub liquid crystal display device DD19. As a result, any malfunction of the projector device B2 can be avoided reliably and promptly by the error notification. Note that the predetermined time is not limited to 1000 ms as an example, and various times such as 500 ms or more can be set if the transmission time interval for one communication is 500 ms.

  FIG. 138 shows a process at the time of projector control reception by the sub CPU 400 of the sub control board SS, as a process according to the tenth modification. The processing illustrated in FIG. 138 is obtained by replacing the processing of S448 illustrated in FIG. 89 described above with the processing of FIG. 140 described below, and deleting only the processing of S449. Therefore, in FIG. 138, the same reference numerals as those in FIG. 89 are used and the description is omitted, and the case of S445: No and the process of S450 will be described.

  As shown in FIG. 138, when there is no request to change the projector setting value (S445: No), the sub CPU 400 proceeds to the processing of S450. In S450, sub CPU 400 performs a status request command transmission process. In this processing, the sub CPU 400 transmits a status request command to the projector control board B23. Thereafter, sub CPU 400 ends the process at the time of projector control reception. In the tenth modification, the parameter request command transmitted from the projector control board B23 does not include a parameter value such as a setting change or a status, and includes, for example, a focus position setting change including a focus position origin adjustment described later. A parameter value indicating whether the request is a change in projector setting value is included. That is, a command for requesting a parameter can be transmitted from the projector control board B23 at an arbitrary timing. Based on the parameter value included in such a command, in S445, it is determined whether or not there is a request to change the projector setting value. Is determined. Note that when a parameter request command is transmitted at an arbitrary timing from the control LSI 230 of the projector control board B23, the sub CPU 400 receives the parameter request command (or, upon receiving the command), the projector B2. If there is a request to change the projector setting value such as the focus position adjustment, the change of the projection content, the movement of the screen, etc., the projector setting value and parameters can be transmitted to the projector device B2. As described above, the projector device B2 side can control the transmission timing of the command transmitted from the sub CPU 400, and the projector device B2 periodically transmits the parameter request command to the sub CPU 400, It is also possible to notify the sub CPU 400 that the command can be received. Further, the timing at which the parameter request command is transmitted from the control LSI 230 of the projector control board B23 to the sub CPU 400 is set to a predetermined interval (for example, 500 ms interval, a constant interval, a constant cycle, etc.), but is not limited thereto. Alternatively, when the sub CPU 400 determines to change the parameters of the projector device B2, the parameters may be transmitted to the projector control board B23. When a parameter request command is transmitted at predetermined intervals from the projector control board B23, transmission / reception processing in one processing (for example, transmission / reception processing during activation of the projector apparatus, transmission / reception processing during parameter change in the projector apparatus, error processing during error processing) , Etc.), a parameter request command may be received a plurality of times, and it is assumed that the start of transmission / reception processing and the reception of a parameter request command in one process do not correspond one-to-one. In such a case, as described above, it is desirable that the sub CPU 400 independently transmits to the projector control board B23 at an arbitrary timing. The command of the parameter request, the command of the reception confirmation transmitted from the projector device B2 to the sub CPU 400, or the command of the setting completion transmitted from the sub CPU 400 to the projector device B2 has a special meaning because the commands are duplicated. Unless otherwise, some commands may be discarded. By regularly transmitting and receiving commands in this way, while monitoring that the communication state is normal, unnecessary commands are discarded (or only reception confirmation of received ones is performed and subsequent processing is performed). , Etc.) can simplify the processing.

  FIG. 139 shows a projector drift correction process by the sub CPU 400 of the sub control board SS as a process according to the tenth modification. The processing shown in FIG. 139 is obtained by improving a part of the processing shown in FIG. 95 described above so as to be suitable for the projector device B2 in FIG.

  As shown in FIG. 139, the sub CPU 400 determines whether or not there is a focus position setting change request based on a parameter request command from the projector control board B23 (S1061). The focus position setting change request is issued when the focus position is to be changed while the drift position is corrected after returning the focus position to a focus origin described later. If there is a request to change the setting of the focus position (S1061: Yes), the sub CPU 400 shifts to the next process of S1062. If there is no request to change the setting of the focus position (S1061: No), the sub CPU 400 proceeds to the process of S1063. In addition, regarding the movement to the focus position, a method of obtaining the focus position after incorporating the drift correction in advance, and moving the focus position according to the offset value without incorporating the drift correction, and then performing the drift correction There is a method of moving the focus position, but either one of the methods may be applied, or one of the methods may be appropriately selected according to the situation. Further, after the focus position is moved by the drift correction, the predetermined focus position may be further moved according to the situation, or the focus movement may be collectively performed from the position before the movement to the position after the movement. The focus position may be moved. The focus control at that time is, for example, when the position before the movement is grasped, when the position after the movement is grasped without grasping the position before the movement, or when only the movement amount is grasped. Various controls are conceivable.

  In S1062, the sub CPU 400 sets a status request command with the projector control board B23 as a transmission destination in the sub device transmission storage area of the sub RAM board 41. At this time, the drift correction temperature is specified as a parameter in the status request command. After that, the sub CPU 400 ends the projector drift correction processing. The command set in the process of S1062 is transmitted to the projector control board B23 by the process of S450 of FIG. 138 described above.

  In S1063, sub CPU 400 determines whether or not the command (reception command) obtained from the reception data is 'drift correction temperature'. If the received command is “drift correction temperature” (S1063: Yes), the sub CPU 400 proceeds to the next step S1064. If the received command is not the “drift correction temperature” (S1063: No), the sub CPU 400 ends the projector drift correction processing.

  Next, the sub CPU 400 acquires the drift correction temperature from the projector status storage area of the sub RAM board 41 and acquires the position coefficient of the focus position (S1064). As described above, the position coefficient of the focus position is a constant factor for obtaining an optimum correction position (focus correction value) according to the temperature characteristics for each of the focus positions A to E.

  Next, the sub CPU 400 calculates a focus drift correction value by multiplying the obtained drift correction temperature and position coefficient (S1065). As described above, the focus drift correction value means a value obtained by correcting the focus position according to the ambient temperature.

  Next, the sub CPU 400 determines whether or not the latest focus drift correction value calculated in S1065 is equal to the existing correction value in the focus correction value storage area of the sub RAM board 41 (S1066). When the latest focus drift correction value is equal to the existing correction value (S1066: Yes), the sub CPU 400 ends the projector drift correction processing. When the latest focus drift correction value is different from the existing correction value (S1066: No), the sub CPU 400 shifts to the next process of S1067.

  Next, the sub CPU 400 overwrites and saves the focus drift correction value in the focus correction value storage area (S1067).

  Next, the sub CPU 400 transmits a command for a request to change the setting of the focus drift correction value to the projector control board B23 (S1068).

  Next, the sub CPU 400 adds 1 to the focus drift correction number counter (S1069). The drift correction number counter is an addition counter for accumulating the number of times the drift correction of the focus position is performed in response to the rewriting of the focus drift correction value by the drift correction temperature. The focus drift correction number counter is set to an initial value in a process in which it is determined that the focus drift correction is performed after returning the focus position to the focus origin, which will be described later, and 1 is added when the focus drift correction is actually performed. You. That is, when the focus drift correction is performed after returning to the focus origin, −1 is set as the initial value of the focus drift correction number counter to count the next focus drift correction as the first time. The initial value of the focus drift correction number counter is also set when the projector device B2 is started. Further, the initial value of the focus drift correction counter may be set to 0 in order to count the case where the focus drift correction is performed after returning the focus position to the origin as the first focus drift correction. Further, when the initial value of the focus drift correction counter is set to 0, the counting may not be performed when the focus drift correction is performed by returning to the focus origin. Regarding the focus drift correction, the temperature (temperature of the LED, the fan, the projector device, etc.) at the time of performing the previous focus drift correction is compared with the temperature at the time of performing the focus drift correction this time, and based on the comparison result. It may be performed in accordance with the amount of change in temperature, or depending on the temperature when (or when) moving the focus (including electric focus movement and image movement by software image processing) and other predetermined conditions. Alternatively, focus adjustment may be performed.

  Next, the sub CPU 400 stores the focus position and the focus drift correction value in the projector setting value storage area of the sub RAM board 41 (S1070). After that, the sub CPU 400 ends the projector drift correction processing. Thus, drift correction of the focus position is performed according to the drift correction temperature. Note that the drift correction is a process of moving the focus position before correction by a difference amount corresponding to the drift correction for each drift correction temperature, and the drift error included in the difference amount increases as the number of times of the drift correction increases. With respect to such a drift error, the focus position is temporarily returned to focus positions A to E (hereinafter, referred to as “focus origin”) serving as reference positions for each projection plane, and thereafter, the focus is shifted to a position corresponding to the adjustment value or the offset. By moving the position and then moving the focus position by an amount corresponding to the drift correction, the drift error accumulated up to that point is eliminated. This will be described later. Note that the calculation of the focus position may be performed by transmitting the electric focus position offset and the focus correction value, which are necessary information, from the sub CPU 400 and performing the calculation based on the information. The drift error is considered to be caused by the following factors. That is, since the electric focus adjustment corresponding to the drift correction temperature is physically performed by using the focus motor 242C, if this is performed, for example, every 1 ° C. change, the drive control of the focus motor 242C is extremely fine. Becomes At this time, when the focus motor 242C is driven quickly and accurately so as not to give a sense of incongruity to the player while projecting an image, the possibility of so-called motor out-of-synch increases. An error occurs between the focus position recognized on the side and the actual physical focus position. Since such a phenomenon is likely to occur when the electric focus adjustment is performed extremely finely, the electric focus is adjusted at a predetermined drift correction temperature (for example, in the case of a temperature change of 1 to 5 ° C.) as described later. This can be dealt with by performing control so that adjustment is not performed. In addition, if the driving speed of the focus motor 242C is suppressed, the possibility of motor loss of synchronization is considered to be reduced. However, there is a demerit that the focus time is increased, and the required focus is required when the image is continuously projected. If the time is spent performing the electric focus adjustment, the image will be disturbed or uncomfortable for the player. This is considered to be particularly likely to occur particularly when a plurality of projection targets (screens) are provided and the projection targets are changed as in the present embodiment. Therefore, when the player does not feel uncomfortable even if the video is visually disturbed (for example, during a demonstration, during a blackout, or during a stage change for a production, etc.), the drive speed of the focus motor 242C is set to a normal value. It is also possible to deal with it by setting the speed to a lower speed.

  FIG. 140 shows a projector setting change process by the sub CPU 400 of the sub control board SS as a process according to the tenth modification. The processing shown in FIG. 140 is obtained by improving a part of the processing shown in FIG. 91 described above so as to be suitable for the projector apparatus B2 in FIG.

  As shown in FIG. 140, the sub CPU 400 extracts the setting change content of the projector setting value received as an argument (S1071).

  Next, the sub CPU 400 determines whether or not the setting change content is a horizontal position offset (horizontal position A to E offset) (S1072). If the content of the setting change is the horizontal position offset (S1072: Yes), the sub CPU 400 proceeds to the next process of S1073. When the setting change content is not the horizontal position offset (S1072: No), the sub CPU 400 shifts to the process of S1074.

  Next, the sub CPU 400 performs a horizontal position offset command transmission process (S1073). In this processing, the sub CPU 400 rewrites the horizontal position offset (horizontal position A to E offset) in the projector setting value storage area of the sub RAM board 41, and sends a command for setting the horizontal position offset to the projector control board B23. Send to. Thereafter, the sub CPU 400 ends the projector setting change processing. Note that the horizontal position offset (horizontal image position offset) in the present embodiment is the horizontal position of the projected image that is horizontally offset-adjusted from the reference position for each projection plane, and the entire projected image is adjusted without electric focus adjustment. Means a position finely adjusted in the horizontal direction.

  In S1074, sub CPU 400 determines whether or not the setting change content is a vertical position offset. If the content of the setting change is the vertical position offset (S1074: Yes), the sub CPU 400 proceeds to the next step S1075. If the content of the setting change is not the vertical position offset (S1074: No), the sub CPU 400 proceeds to the process of S1076.

  Next, the sub CPU 400 performs a vertical position offset command transmission process (S1075). In this process, the sub CPU 400 rewrites the vertical position offset in the projector setting value storage area of the sub RAM board 41, and transmits a command for setting the vertical position offset to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing. Note that the vertical position offset (vertical image position offset) in the present embodiment is a vertical position of a projected image that is vertically offset-adjusted from a reference position for each projection plane. Means a position finely adjusted in the vertical direction. That is, since the horizontal position offset and the vertical position offset control which two-dimensional position within the projection range the projected image is displayed, the projected image can be moved without electric focus adjustment. It is. The focus position may be moved by the electric focus adjustment, and the horizontal position or the vertical position of the projected image may be moved at the time of rendering, and the position of the projected image may be changed by software image processing. Further, the electric focus adjustment may be performed based on the values of the horizontal position offset and the vertical position offset.

If the setting change is not the focus offset (S1076: No), the sub CPU 400 proceeds to the process of S1079.

  Next, the sub CPU 400 performs a focus origin adjustment instruction transmission process (S1077). This processing will be described later with reference to FIG. After that, the sub CPU 400 performs a focus position offset command transmission process (S1078).

It is transmitted to the substrate B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1079, sub CPU 400 determines whether or not the setting change is focus drift correction. If the setting change is focus drift correction (S1079: Yes), the sub CPU 400 proceeds to the next step S1080. If the setting change is not focus drift correction (S1079: No), the sub CPU 400 shifts to the processing of S1082.

  Next, the sub CPU 400 performs focus origin adjustment instruction transmission processing (S1080). This processing is the same as the processing of S1077, and will be described later with reference to FIG. After that, the sub CPU 400 performs a focus drift correction value command transmission process (S1081). In this processing, the sub CPU 400 rewrites the focus drift correction values A to E in the projector setting value storage area of the sub RAM board 41 and sets a command (focus drift correction value command) for setting the focus drift correction values A to E. Is transmitted to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1082, sub CPU 400 determines whether or not the setting change is LED brightness setting. When the setting change content is the LED brightness setting (S1082: Yes), the sub CPU 400 shifts to the next process of S1083. When the setting change content is not the LED brightness setting (S1082: No), the sub CPU 400 shifts to the process of S1084.

  Next, the sub CPU 400 performs an LED brightness setting command transmission process (S1083). In this process, the sub CPU 400 rewrites the LED brightness setting in the projector setting value storage area of the sub RAM board 41, and transmits a command for setting the LED brightness to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1084, sub CPU 400 determines whether or not the setting change is a trapezoidal distortion correction value. When the setting change content is the trapezoidal distortion correction value (S1084: Yes), the sub CPU 400 shifts to the next process of S1085. When the setting change content is not the trapezoidal distortion correction value (S1084: No), the sub CPU 400 shifts to the process of S1086.

  Next, the sub CPU 400 performs a trapezoidal distortion correction value command transmission process (S1085). In this process, the sub CPU 400 rewrites the trapezoidal distortion correction value in the projector setting value storage area of the sub RAM board 41, and transmits a command for setting the trapezoidal distortion correction value to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1086, sub CPU 400 determines whether or not the setting change content is a contrast setting. If the content of the setting change is the contrast setting (S1086: Yes), the sub CPU 400 shifts to the next process of S1087. If the content of the setting change is not the contrast setting (S1086: No), the sub CPU 400 proceeds to the process of S1088.

  Next, the sub CPU 400 performs a contrast setting command transmission process (S1087). In this process, the sub CPU 400 rewrites the contrast setting in the projector setting value storage area of the sub RAM board 41 and transmits a command for setting the contrast to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1088, sub CPU 400 determines whether or not the setting change content is gamma setting. If the setting change is gamma setting (S1088: Yes), the sub CPU 400 proceeds to the next step S1089. When the setting change content is not the gamma setting (S1088: No), the sub CPU 400 shifts to the processing of S1090.

  Next, the sub CPU 400 performs a gamma setting command transmission process (S1089). In this process, the sub CPU 400 rewrites the gamma setting in the projector setting value storage area of the sub RAM board 41, and transmits a command for setting the gamma value to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1090, sub CPU 400 determines whether the setting change content is the white color temperature or not. When the setting change content is the white color temperature (S1090: Yes), the sub CPU 400 shifts to the next process of S1091. When the setting change content is not the white color temperature (S1090: No), the sub CPU 400 shifts to the processing of S1092.

  Next, the sub CPU 400 performs a white color temperature command transmission process (S1091). In this process, the sub CPU 400 rewrites the white color temperature in the projector setting value storage area of the sub RAM board 41, and transmits a command for setting the white color temperature to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1092, sub CPU 400 determines whether or not the setting change content is brightness. If the setting change is brightness (S1092: Yes), the sub CPU 400 proceeds to the next step S1093. If the setting change content is not brightness (S1092: No), the sub CPU 400 shifts to the processing of S1094.

  Next, the sub CPU 400 performs a brightness command transmission process (S1093). In this process, the sub CPU 400 rewrites the brightness in the projector setting value storage area of the sub RAM board 41, and transmits a command for setting the brightness to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing.

  In S1094, sub CPU 400 determines whether or not the setting change content is a test pattern. If the setting change is a test pattern (S1094: Yes), the sub CPU 400 proceeds to the process of the next S1095. If the setting change is not a test pattern (S1094: No), the sub CPU 400 ends the projector setting change process.

  Next, the sub CPU 400 performs a test pattern command transmission process (S1095). In this process, the sub CPU 400 rewrites the test pattern in the projector setting value storage area of the sub RAM board 41 and transmits a command for setting the test pattern to the projector control board B23. Thereafter, the sub CPU 400 ends the projector setting change processing. Such a projector setting change process is executed when a maintenance worker at a game hall or an inspection worker performs various optical adjustments to the projector device B2 before shipping from a factory.

  FIG. 141 illustrates a focus origin adjustment instruction transmission process performed by the sub CPU 400 of the sub control board SS as the process according to the tenth modification.

  As shown in FIG. 141, the sub CPU 400 determines whether the focus origin adjustment flag is “ON” (S1101). The origin adjustment flag is flag information for designating whether to return the focus position to the focus origin. When the focus origin adjustment flag is “ON” (S1101: Yes), the sub CPU 400 proceeds to the next step S1102. If the focus origin adjustment flag is not “ON” (S1101: No), the sub CPU 400 ends the focus origin adjustment instruction transmission process.

  In S1102, sub CPU 400 sets a command indicating a focus origin adjustment instruction. This command is transmitted to the projector control board B23 together with the focus position offset command or the focus drift correction value command by the processing of S1078 and S1081 of FIG. 140 described above.

  Next, the sub CPU 400 sets the focus origin adjustment flag to “OFF”. After that, the sub CPU 400 ends the focus origin adjustment instruction transmission processing.

  FIG. 142 illustrates a projector control process by the sub CPU 400 of the sub control board SS as the process according to the tenth modification. The processing shown in FIG. 142 is obtained by improving a part of the processing shown in FIG. 88 described above so as to be suitable for the projector device B2 in FIG.

  As shown in FIG. 142, the sub CPU 400 determines whether or not the transmission source ID of the reception data temporarily stored in the sub device reception storage area of the sub RAM board 41 indicates "projector" (S1110). If the transmission source ID indicates "projector" (S1110: Yes), the sub CPU 400 proceeds to the next step S1111. If the transmission source ID does not indicate “projector” (S431: No), the sub CPU 400 proceeds to the process of S1118.

  Next, the sub CPU 400 performs a projector control received data consistency check process for controlling the projector device B2 (S1111). In this processing, the sub CPU 400 checks whether or not the value of the command ID included in the received data matches the values of '81H' to '8BH' indicating the transmission command from the projector control board B23 shown in FIG. And returns the check result as a return value.

  Next, the sub CPU 400 sets 0 to the reception counter of the projector control reception data (S1112). The reception counter is for counting commands transmitted from the control LSI 230 at a transmission cycle of 500 ms as an example in the present embodiment. For example, if the value of the reception counter is 3 or more, at least 1000 ms has elapsed since the reception counter was reset to 0.

  Next, the sub CPU 400 determines whether or not there is an abnormality in the consistency of the received data from the return value of the check result in the processing of S1111 (S1113). If there is an abnormality in the consistency of the received data (S1113: Yes), the sub CPU 400 proceeds to the next process of S1114. If there is no abnormality in the consistency of the received data (S1113: No), the sub CPU 400 shifts to the processing of S1115.

  Next, the sub CPU 400 discards the data in the sub device reception storage area (S1114). After that, the sub CPU 400 shifts to the process of S1118.

  In S1115, sub CPU 400 performs focus origin adjustment determination processing. This processing will be described later with reference to FIG.

  Next, the sub CPU 400 performs a process at the time of projector control reception (S1116). This processing corresponds to the processing of FIG. 138 described above.

  Next, the sub CPU 400 performs a projector drift correction process (S1117). This processing corresponds to the processing of FIG. 139 described above. Thereafter, sub CPU 400 ends the projector control process.

  In S1118, sub CPU 400 adds 1 to the reception counter of the projector control reception data.

  Next, the sub CPU 400 determines whether or not the value of the reception counter of the projector control reception data is 3 or more (S1119). That is, sub CPU 400 determines whether or not at least 1000 ms has elapsed since resetting the reception counter. If the value of the reception counter is 3 or more and at least 1000 ms has elapsed (S1119: Yes), the sub CPU 400 proceeds to the next process of S1120. On the other hand, when the value of the reception counter is less than 2 and 1000 ms has not elapsed (S1119: No), the sub CPU 400 ends the projector control process.

  In S1120, sub CPU 400 causes sub liquid crystal display device DD19 to display an image or the like relating to the error notification. Thereafter, sub CPU 400 ends the projector control process.

  FIG. 143 shows focus origin adjustment determination processing by the sub CPU 400 of the sub control board SS as processing according to the tenth modification.

  As shown in FIG. 143, the sub CPU 400 determines whether or not to shift to the demonstration (at the time of receiving the demo command) (S1121). The demonstration means a state where an image similar to an actual effect is displayed by the projector device B2 or the like when a predetermined time has elapsed without inserting medals, and the demonstration command is the main CPU 300 of the main control board MS. Is transmitted to the sub CPU 400 when the mode shifts to the demo mode. The demo command transmission process will be described later with reference to FIG. If it is time to shift to the demonstration (S1121: Yes), the sub CPU 400 shifts to the process of S1128. If it is not time to shift to the demonstration ((S1121): No), the sub CPU 400 shifts to the next process of S1122.

  In S1122, sub CPU 400 determines whether or not a chance time (hereinafter, referred to as “CT”) has started as a gaming state. The CT is a game state in which the reel screen mechanism F1, for example, is projected, and advancing while displaying an effect image. The transition of the game state including the CT will be described later with reference to FIG. When it is time to start CT (S1122: Yes), the sub CPU 400 proceeds to the process of S1128. If it is not time to start CT, the sub CPU 400 shifts to the next process of S1123.

  In S1123, sub CPU 400 determines whether or not the origin adjustment of the focus position has been selected by the setting in the member menu. When the player performs a predetermined operation (for example, a password input operation) on the touch panel DD19T, the member menu is called as a screen as shown in FIG. 124. In the member menu screen, the focus position is set. The player can arbitrarily select whether or not to adjust the origin. When the origin adjustment of the focus position is selected by the member menu (S1123: Yes), the sub CPU 400 proceeds to the process of S1128. When the origin adjustment of the focus position is not selected by the member menu, the sub CPU 400 shifts to a process of the next S1124.

  In S1124, the sub CPU 400 acquires the value of the focus drift correction number counter as the number of drift corrections, and determines whether or not the number of drift corrections is, for example, 30 or more as a predetermined value. When the number of times of drift correction is equal to or more than the predetermined value (S1124: Yes), the sub CPU 400 shifts to the processing of S1125. When the number of times of drift correction is less than the predetermined value (S1124: No), the sub CPU 400 proceeds to the process of S1126.

  In S1125, sub CPU 400 sets −1 as an initial value in the focus drift correction number counter. After that, the sub CPU 400 shifts to the process of S1128.

  In S1126, the sub CPU 400 determines whether or not the number of symbol changes (or the number of games, the number of starts, etc.) has reached, for example, 300 or more in a state where the focus origin adjustment flag is “OFF”. The symbol variation number means the number of times that the reels RL, RC, RR are rotationally driven, and the symbol (identification information) is counted each time the variation display is started. The number of symbol changes (the number of times the identification information is changed) is counted using a change number counter. If the focus origin adjustment flag is “OFF” and the number of symbol changes has reached, for example, 300 or more (S1126: Yes), the sub CPU 400 proceeds to the next step S1127. Even if the focus origin adjustment flag is “OFF”, if the number of symbol changes is, for example, less than 300 (S1126: No), the sub CPU 400 ends the focus origin adjustment determination processing.

  In step S1127, the sub CPU 400 clears the value of the change number counter that counts the number of symbol changes when the focus origin adjustment flag is “OFF”.

  Next, the sub CPU 400 sets the focus origin adjustment flag to 'ON' (S1128).

  Next, the sub CPU 400 issues a focus position setting change request to change the focus position while performing drift correction after returning the focus position to the focus origin (S1129). In this processing, the sub CPU 400 stores the setting change request data including the origin adjustment of the focus position in the sub device transmission storage area of the sub RAM board 41, and transmits this data to the projector device B2. The focus position setting change request data includes the content of changing the focus position after returning the focus position to the focus origin. Thus, for example, when the screen on which the image is to be projected is switched, the projector device B2 controls the focus mechanism 242 based on the focus position setting change request data, thereby temporarily returning the focus position to the focus origin, respectively. The focus of the projection lens 210 can be adjusted while performing drift correction to a focus position corresponding to the screen. After that, the sub CPU 400 ends the focus origin adjustment determination process.

  According to the processing of FIGS. 138 to 143, the focus position is compensated by the drift correction even when the temperature of the projector device B2 rises, and the drift error accumulates for each drift correction. By changing the setting so that the focus position temporarily returns to the focus origin in accordance with the game state (CT) and the member menu, all the drift errors accumulated up to that point are removed. Therefore, with respect to the image projected from the projector device B2 while performing the drift correction during the electric focus control, it is possible to effectively suppress the image quality deterioration due to the drift correction at an appropriate timing.

  Also, when the number of times of drift correction becomes a predetermined number of times, for example, 30 or more, by changing the setting so that the focus position temporarily returns to the focus origin at the time of drift correction, all the drift errors accumulated so far are removed. Therefore, even with this, it is possible to effectively suppress image quality deterioration due to drift correction for an image projected from the projector device B2 while repeatedly performing drift correction.

  In addition, even when the number of symbol changes becomes, for example, 300 or more as the predetermined number of times without returning the focus position to the focus origin, by changing the setting so that the focus position temporarily returns to the focus origin, the drift accumulated up to that time is changed. Since all errors are removed, deterioration of image quality due to drift correction can be effectively suppressed for an image projected from the projector device B2 by repeatedly changing the focus position.

  The control entity that changes the setting of the focus position is not limited to the sub CPU 400. For example, the control LSI 230 of the projector device B2 itself may change the setting of the focus position. In this case, the control LSI 230 automatically adjusts the focus position by, for example, monitoring the LED temperature and performing feedback control so as to perform drift correction after returning the focus position to the focus origin according to the LED temperature. be able to. At this time, whether or not the setting change accompanying the origin adjustment of the focus position can be appropriately determined in accordance with a flag and a condition regarding the origin adjustment of the focus position.

  Further, according to the present embodiment, for example, a main series of projector control processing is executed in response to a command transmitted from the projector apparatus B2 at a transmission cycle of 500 ms, and the focus position is determined by the processing of S1115 in this series of processing. It is determined whether or not to perform the origin adjustment. Therefore, the timing at which the origin of the focus position is actually adjusted may be delayed from a point in time when a predetermined condition is satisfied due to a slight time lag. The command may be immediately transmitted to the control LSI 230 of the projector B2 when a predetermined condition is satisfied. When it is necessary to transmit a command to change the focus position, the command may be transmitted immediately at that time. Upon receiving such a command, the projector device B2 immediately adjusts the origin of the focus position, and can change the focus position while performing drift correction.

  FIG. 144 illustrates an effect content determination process by the sub CPU 400 of the sub control board SS as the process according to the eleventh modification. The processing shown in FIG. 144 corresponds to the effect content determination processing of S222 shown in FIG. 71 which is suitable to be performed while adjusting the origin of the focus position. FIG. 145 shows a display example of an image projected by the projector device B2 according to the eleventh modification.

  As shown in FIG. 144, the sub CPU 400 determines the effect content according to the command transmitted from the main CPU 300 of the main control board MS (S1131).

  Next, the sub CPU 400 determines whether or not the effect involves a change in the focus position that requires screen switching based on the determined effect contents (S1132). If the effect involves a change in the focus position (S1132: Yes), the sub CPU 400 proceeds to the process of S1137. If the effect does not involve a change in the focus position (S1132: No), the sub CPU 400 proceeds to the next step S1133.

  In S1133, the sub CPU 400 acquires the value of the focus drift correction number counter as the number of drift corrections, and determines whether or not the number of drift corrections is, for example, 15 or more as a predetermined value. If the number of drift corrections is equal to or more than the predetermined value (S1133: Yes), the sub CPU 400 proceeds to the next step S1134. If the number of drift corrections is less than the predetermined value (S1133: No), the sub CPU 400 determines the effect content determined in the process of S1131, and ends the effect content determination process.

  In S1134, the sub CPU 400 discards the effect content determined in the process of S1131, and changes the effect content to an effect with a change in the focus position.

  Next, the sub CPU 400 sets the focus origin adjustment flag to 'ON' (S1135).

  Next, the sub CPU 400 sets -1 as an initial value in the focus drift correction number counter (S1136).

  Then, as an effect changed in the processing of S1134, the sub CPU 400 requests the focus position setting change request in order to project the image while changing the focus position while performing drift correction after temporarily returning the focus position to the focus origin. Is performed (S1137). As a result, as the effect image projected from the projector device B2, for example, as shown in FIG. 145 (a), once the focus position returns to the focus origin, so-called out-of-focus occurs and corresponds to, for example, an internal winning combination. The image becomes difficult to see, and thereafter, as shown in FIG. 145 (b), the image is displayed such that the pattern can be clearly seen by gradually adjusting the focus position to the position corresponding to the screen to be projected. .

  According to such effect content determination processing, the focus position is compensated by the drift correction even due to the temperature rise of the projector device B2, and the drift error accumulates for each drift correction. Since the focus position can be temporarily returned to the focus origin in order to project an effect image that changes to a clearly visible state, all the drift errors accumulated so far can be removed. For this reason, it is possible to suppress the image quality deterioration due to the drift correction while using the image projected from the projector device B2 while performing the drift correction at the time of the electric focus control.

  The image shown in FIG. 145 is, for example, a state in which the focus is initially shifted and the visibility is lowered, and the state is gradually changed to a state where the focus is gradually focused and the visibility is improved. The state in which the visibility changes due to the change in the video content can be provided as the video content for the effect. More specifically, such a video expression includes a predetermined effect image (for example, a specific small image) that informs a player of a lottery result such as an internal winning combination, a rare combination, a reach symbol, a big hit symbol, or the like. Cherry, watermelon, numbers, letters, symbols, character images, video, effects, etc. Can be provided. At this time, since the outline and color arrangement of the projected predetermined effect image are vaguely visually recognized by the player, when performing the effect with the origin adjustment, the effect with the origin adjustment is, for example, 10,000 ms. At the same time, if the time required for the origin adjustment in the effect is, for example, 2500 ms, the first 1500 ms displays a common image such as a treasure chest, and the remaining 1000 ms ends the effect (elapse of the effect time for 7500 ms). The above-described predetermined effect image may be displayed. In this way, when the origin is adjusted and the player has a vague grasp of the outline and color scheme, the final display content is not understood, and the notification is made by the effect image at the timing when the outline becomes clear You can also. In addition, in the production accompanied by the origin adjustment, at which timing within the production time the origin adjustment is performed, for example, at the same time as the production start of 10,000 ms, during the production that is 5000 ms after, or when 7500 ms elapses It can be changed as appropriate according to the effect, such as the timing at the end of the effect, and such information on the origin adjustment timing may be stored in advance or may be changed as appropriate according to the situation. Or you may make it select. In addition, when the production time is not predetermined (for example, when the identification symbol capable of displaying the game result to the player is stopped according to the operation of the operation means), the treasure chest or the predetermined production The timing at which the image is displayed is determined by the operation of the player's operation means (for example, the operation of the reel stop button, the operation of the effect operation means provided on the gaming machine, the operation of the lever, the operation of payout, the operation of lending, There is a case where the displayed timing is different depending on the operation of the bet or the MAX bet, the operation of the button which can be moved to the standby position and the protruding position and can be pressed at any position, etc., but in such a case, for example, The origin adjustment may be executed on condition that the operation means is operated while the identification symbol is changing. Then, when it is determined in advance that it is the execution period of the effect of performing the origin adjustment, the origin adjustment is executed on condition that the operation means is operated, and the origin adjustment is performed, and the treasure box and the predetermined effect image described above are performed. May be displayed.

  FIG. 146 shows a rendering content determination process by the sub CPU 400 of the sub control board SS as a process according to the twelfth modification. The processing illustrated in FIG. 146 corresponds to a modified example of the processing illustrated in FIG. 144.

  As shown in FIG. 146, the sub CPU 400 determines the effect content according to the command transmitted from the main CPU 300 of the main control board MS (S1141).

  Next, the sub CPU 400 determines whether or not the effect involves a change in the focus position that requires screen switching based on the determined effect contents (S1142). If the effect involves a change in the focus position (S1142: Yes), the sub CPU 400 proceeds to the process of S1148. If the effect does not involve a change in the focus position (S1142: No), the sub CPU 400 proceeds to the next process of S1143.

  In S1143, the sub CPU 400 acquires the value of the focus drift correction number counter as the number of drift corrections, and determines whether or not the number of drift corrections is, for example, 15 or more as a predetermined value. If the number of times of drift correction is equal to or greater than the predetermined value (S1143: Yes), the sub CPU 400 proceeds to the next step S1144. When the number of times of drift correction is less than the predetermined value (S1143: No), the sub CPU 400 determines the effect content determined in the process of S1141, and ends the effect content determination process.

  In S1144, the sub CPU 400 determines whether or not the internal winning combination is a specific internal winning combination corresponding to a rare combination such as a so-called RT transfer combination or a bonus combination, based on the received command. If the internal winning combination is a specific internal winning combination (S1144: Yes), the sub CPU 400 proceeds to the next processing of S1145. When the internal winning combination is not a specific internal winning combination (S1144: No), the sub CPU 400 determines the effect content determined in the process of S1141, and ends the effect content determination process.

  In S1145, the sub-CPU 400 discards the effect content determined in the processing of S1141, and changes the effect content to an effect with a change in the focus position.

  Next, the sub CPU 400 sets the focus origin adjustment flag to “ON” (S1146).

  Next, the sub CPU 400 sets -1 as an initial value in the focus drift correction number counter (S1147).

  Then, as an effect changed in the process of S1145, the sub CPU 400 requests the focus position setting change request in order to project the video while changing the focus position while performing drift correction after returning the focus position to the focus origin once. Is performed (S1148). According to this, the effect content once determined according to the internal winning such as the rare role having a relatively low winning probability is changed, and at this time, the effect image projected from the projector device B2 is as shown in FIG. An image similar to the one shown is displayed. Note that such effect content determination processing may be executed only when the number of games reaches a predetermined number without a specific internal winning combination being internally won.

  Even with such effect content determination processing, when projecting an image for effect with a relatively low appearance frequency, the focus position can be returned to the focus origin once, and all the drift errors accumulated at that time can be removed. As a result, image quality deterioration due to drift correction can be suppressed.

  FIG. 147 shows a rendering content determination process by the sub CPU 400 of the sub control board SS as a process according to the thirteenth modification. The processing illustrated in FIG. 147 corresponds to a modified example of the processing illustrated in FIG. 144 or 146.

  As shown in FIG. 147, the sub CPU 400 determines the effect content according to the command transmitted from the main CPU 300 of the main control board MS (S1151).

  Next, the sub CPU 400 determines whether or not the effect involves a change in the focus position that requires a screen switch based on the determined effect contents (S1152). If the effect involves a change in the focus position (S1152: Yes), the sub CPU 400 proceeds to the process of S1157. If the effect does not involve a change in the focus position (S1152: No), the sub CPU 400 proceeds to the next process of S1153.

  In S1153, the sub CPU 400 acquires the value of the focus drift correction number counter as the number of drift corrections, and determines whether the number of drift corrections is, for example, 15 or more as a predetermined value. If the number of times of drift correction is equal to or more than the predetermined value (S1153: Yes), the sub CPU 400 proceeds to the next process of S1154. If the number of drift corrections is less than the predetermined value (S1153: No), the sub CPU 400 determines the effect content determined in the process of S1151, and ends the effect content determination process.

  In S1154, the sub CPU 400 determines whether or not the effect content determined in the process of 1151 is an effect accompanied by darkening of the video. The effect with the darkening of the image means, for example, an effect of temporarily changing the projection target from one screen to another screen so as to temporarily make the image dark in the switching. If the effect involves darkening of the image (S1154: Yes), the sub CPU 400 proceeds to the next process of S1155. If the effect is not an effect accompanied by darkening of the image (S1154: No), the sub CPU 400 determines the effect content determined in the process of S1151, and ends the effect content determination process.

  In S1155, the sub CPU 400 sets the focus origin adjustment flag to 'ON' while keeping the effect content determined in the process of S1151.

  Next, the sub CPU 400 sets −1 as an initial value in the focus drift correction number counter (S1156).

  Then, the sub CPU 400 issues a focus position setting change request to project a relatively dark image while changing the focus position while performing drift correction after temporarily returning the focus position to the focus origin when the image darkens. (S1157). According to this, at the time of darkening of the image accompanying the screen switching, as the image projected from the projector device B2, an image that is relatively dark and an out-of-focus state cannot be visually recognized is displayed. . Note that such effect content determination processing may be executed only when the image is simply darkened to a predetermined level without switching the screen.

  According to such an effect content determination process, it is possible to temporarily return the focus position to the focus origin in a specific effect state of darkening of an image in which it is difficult for a player to defocus, and to remove all drift errors accumulated at that time. As a result, it is possible to suppress image quality deterioration due to subsequent drift correction.

  FIG. 148 shows a drift correction temperature table stored in the sub-ROM board 42 of the sub-control board SS as a table according to the fourteenth modification.

  As shown in FIG. 148, in the drift correction temperature table, for example, the drift correction temperature is effectively applied as a data value to the drift correction temperature obtained via the temperature sensor B25 in accordance with the temperature change situation. Whether or not is defined in a predetermined temperature range.

  For example, when the temperature change per minute is 10 ° C. or more for the drift correction temperature obtained via the temperature sensor B25, the drift correction temperature specified as the data effective value A is applied. According to this, the drift correction temperature is applied as it is as the data effective value A irrespective of a temperature difference from a predetermined reference temperature. That is, when there is a relatively rapid temperature change, the drift correction temperature is made valid as it is as a data value for calculating the focus drift correction value.

  On the other hand, with respect to the drift correction temperature obtained via the temperature sensor B25, when the temperature change per minute is less than 10 ° C., the drift correction temperature specified as the data effective value B is applied. According to this, the drift correction temperature becomes 0 ° C. as a data effective value B to be applied when a temperature difference from a predetermined reference temperature is detected within a range of 0 ° C. to ± 11 ° C. , + 11 ° C. or more and −11 ° C. or less, the data is applied as it is as the valid data value B to be applied. That is, when the temperature change is relatively gradual, the drift correction temperature is not validated as a data value for calculating the focus drift correction value unless the temperature difference from the reference temperature exceeds ± 11 ° C. If the difference is within the temperature range of ± 11 ° C., the drift correction is not performed. The temperature change per minute in the present embodiment is, for example, a temperature measured during a predetermined time (for example, a time that is not limited to one minute and may be obtained by time management using a real-time clock or the like). The maximum value and the minimum value of the temperature measured during a predetermined time, and the intermediate value between the maximum value and the minimum value, and the previous drift correction May be obtained as a temperature change per minute in comparison with the temperature at the time of performing (or the temperature at the time of turning on the power).

  FIG. 149 shows a projector drift correction process by the sub CPU 400 of the sub control board SS as a process according to the fourteenth modification. The processing shown in FIG. 149 corresponds to a modification of the processing shown in FIG. 95 or FIG. 139 described above, and is partially improved as processing using the drift correction temperature table in FIG. 148.

  As shown in FIG. 149, the sub CPU 400 determines whether there is a request to change the setting of the focus position based on a parameter request command from the projector control board B23 (S1161). When there is a request to change the setting of the focus position (S1161: Yes), the sub CPU 400 shifts to the next process of S1163. If there is no request to change the setting of the focus position (S1161: No), the sub CPU 400 proceeds to the next step S1162.

  In S1162, sub CPU 400 determines whether or not the value of the drift correction monitoring counter is equal to or larger than a predetermined value, for example, 120 (corresponding to approximately one minute). The drift correction monitoring counter is, for example, an addition counter for measuring time to monitor a temperature change per minute. If the value of the drift correction monitoring counter is equal to or more than the predetermined value (S1162: Yes), the sub CPU 400 proceeds to the next step S1163. When the value of the drift correction monitoring counter is less than the predetermined value (S1162: No), the sub CPU 400 proceeds to the process of S1165.

  In S1163, sub CPU 400 clears the value of the drift correction monitoring counter.

  Next, the sub CPU 400 sets a status request command with the projector control board B23 as a transmission destination in the sub device transmission storage area of the sub RAM board 41 (S1164). At this time, the drift correction temperature is specified as a parameter in the status request command. After that, the sub CPU 400 ends the projector drift correction processing. The command set in the process of S1164 is transmitted to the projector control board B23 by the process of S450 in FIG. 138 described above.

  In S1165, sub CPU 400 determines whether or not the command (received command) acquired from the received data is 'drift correction temperature'. If the received command is “drift correction temperature” (S1165: Yes), the sub CPU 400 proceeds to the next step S1166. If the received command is not the “drift correction temperature” (S1165: No), the sub CPU 400 ends the projector drift correction processing.

  In S1166, the sub CPU 400 obtains the drift correction temperature from the projector status storage area of the sub RAM board 41 and obtains the position coefficient of the focus position. As described above, the position coefficient of the focus position is a constant factor for obtaining an optimum correction position (focus correction value) according to the temperature characteristics for each of the focus positions A to E.

  Next, the sub CPU 400 refers to the drift correction temperature table of FIG. 148 based on the temperature change per minute and selects a valid drift correction temperature data value as the focus drift correction value (S1167). At this time, for example, when the temperature change per minute is 10 ° C. or more, the drift correction temperature is directly selected as the data effective value A irrespective of the temperature difference from a predetermined reference temperature. On the other hand, when the temperature change per minute is less than 10 ° C., if the temperature difference from the predetermined reference temperature is within the range of 0 ° C. to ± 11 ° C., 0 ° C. is set as the data valid value B. If the selected value is not less than + 11 ° C. and not more than -11, it is selected as the data valid value B as it is.

  Next, the sub CPU 400 calculates a focus drift correction value by multiplying the drift correction temperature and the position coefficient selected as the data effective value (S1168). As described above, the focus drift correction value means a value obtained by correcting the focus position according to the ambient temperature (drift correction temperature). At this time, if 0 ° C. is selected as the data valid value, the focus drift correction value becomes 0, and no drift correction is performed.

  Next, the sub CPU 400 determines whether or not the latest focus drift correction value calculated in S1168 is equal to the existing correction value in the focus correction value storage area of the sub RAM board 41 (S1169). When the latest focus drift correction value is equal to the existing correction value (S1169: Yes), the sub CPU 400 ends the projector drift correction processing. If the latest focus drift correction value is different from the existing correction value (S1169: No), the sub CPU 400 proceeds to the next step S1170.

  In S1170, sub CPU 400 overwrites and saves the focus drift correction value in the focus correction value storage area.

  Next, the sub CPU 400 transmits a command for a request to change the setting of the focus drift correction value to the projector control board B23 (S1171).

  Next, the sub CPU 400 sets −1 as an initial value in the focus drift correction number counter (S1172).

  Next, the sub CPU 400 stores the focus position and the focus drift correction value in the projector setting value storage area of the sub RAM board 41 (S1173). After that, the sub CPU 400 ends the projector drift correction processing. Thus, when the drift correction temperature is selected as a data valid value other than 0, drift correction of the focus position is performed.

  According to such a projector drift correction process, for example, a temperature range in which the drift correction becomes invalid is set according to a temperature change per minute, and there are cases where drift correction is performed and the case where drift correction is not performed even at the same drift correction temperature. Yes, drift correction is appropriately performed according to the situation of temperature change. This also makes it possible to reduce the drift error accumulated for each drift correction as much as possible, thereby effectively suppressing the deterioration of the image quality of the image projected from the projector device B2.

  FIG. 150 is a diagram showing a drift correction temperature table stored in the sub-ROM board 42 of the sub-control board SS as a table according to the fifteenth modification. This drift correction temperature table corresponds to a modified example of the drift correction temperature table shown in FIG.

  As shown in FIG. 150, in the drift correction temperature table, for example, the drift correction temperature obtained via the temperature sensor B25 is changed according to whether the demonstration display is being performed or not in addition to the temperature change status. Whether the corrected temperature is effectively applied as a data value is defined in a predetermined temperature range.

  For example, in a case other than during the demonstration display, when the temperature change per minute is 10 ° C. or more (in the case of a temperature change a) with respect to the drift correction temperature obtained via the temperature sensor B25, the data effective value A The specified drift correction temperature is applied. According to this, the drift correction temperature is applied as it is as the data effective value A irrespective of a temperature difference from a predetermined reference temperature. That is, when a predetermined image corresponding to a game state is projected and there is a relatively sharp temperature change as a display other than during the demonstration display, for example, as an effect display, the drift correction temperature is a data value for calculating the focus drift correction value. Is valid as it is.

  On the other hand, even in the case other than during the demonstration display, when the temperature change per minute is less than 10 ° C. (in the case of temperature change b), the data is valid for the drift correction temperature obtained via the temperature sensor B25. The drift correction temperature specified as value B 'is applied. According to this, when the temperature difference from the predetermined reference temperature is detected within the range of 0 ° C. to ± 6 ° C., the drift correction temperature is 0 ° C. as the data effective value B ′ to be applied. When the temperature is detected at + 6 ° C. or more and −6 ° C. or less, the data is applied as it is as the applicable data effective value B ′. That is, when the temperature change is relatively gradual except during the demonstration display, the drift correction temperature is effective as a data value for calculating the focus drift correction value unless the temperature difference from the reference temperature exceeds ± 6 ° C. Therefore, the drift correction is not performed when the temperature difference is within the temperature range of ± 6 ° C.

  In addition, during the demonstration display, the drift correction temperature specified as the data effective value B is applied to the drift correction temperature obtained via the temperature sensor B25 regardless of the temperature change per minute. According to this, the drift correction temperature becomes 0 ° C. as a data effective value B to be applied when a temperature difference from a predetermined reference temperature is detected within a range of 0 ° C. to ± 11 ° C. , + 11 ° C. or more and −11 ° C. or less, the data is applied as it is as the valid data value B to be applied. That is, during the demonstration display, there is no need to project an image with high image quality even after drift correction, so that the drift correction temperature is set to the focus unless the temperature difference from the reference temperature exceeds ± 11 ° C. It is not validated as a data value for calculating the drift correction value, and the drift correction is not performed when the temperature difference is within a temperature range of ± 11 ° C.

  FIG. 151 shows a demo command transmission process by the main CPU 300 of the main control board MS as a process according to the fifteenth modification. The processing shown in FIG. 151 is sequentially executed in the above-described medal acceptance / start check processing of, for example, S103 shown in FIG. 59, or sequentially with each processing shown in FIG.

  As shown in FIG. 151, the main CPU 300 determines whether or not a medal can be inserted (including a state in which a BET button can be operated) (S1181). If the medal can be inserted (S1181: Yes), the main CPU 300 shifts to the next step S1182. When the medal can not be inserted (S1181: No), the main CPU 300 ends the demo command transmission process.

  In S1182, main CPU 300 determines whether or not the error flag is “1”. The error flag is flag information for indicating whether or not there is a communication error or the like between the main control board MS and the connection board, and “1” is set when there is an error. When the error flag is “1” (S1182: Yes), the main CPU 300 shifts the processing to S1188. If the error flag is not “1” but “0” (S1182: No), the main CPU 300 shifts to the next step S1183.

  In S1183, main CPU 300 determines whether or not the demo command transmission flag is "1". The demo command transmission flag is flag information for indicating whether or not the demo command can be transmitted to the sub-control board SS, and is set to "1" when the demo command can be transmitted. When the demo command transmission flag is “1” (S1183: Yes), the main CPU 300 shifts to the processing of S1186. If the demo command transmission flag is not “1” but “0” (S1183: No), the main CPU 300 shifts to the next step S1184.

  In S1184, main CPU 300 sets the initial value of the demo command transmission timer. The demo command transmission timer is a subtraction timer for measuring a standby time until a demo command is transmitted, and a numerical value corresponding to the standby time, for example, 30 s or 60 s is set as an initial value.

  Next, the main CPU 300 sets "1" to the demo command transmission flag (S1185).

  Next, the main CPU 300 subtracts 1 from the value of the demo command transmission timer (S1186).

  Next, the main CPU 300 determines whether or not the value of the demo command transmission timer is “0” (S1187). When the value of the demo command transmission timer is “0” (S1187: Yes), the main CPU 300 shifts to the next step S1188. If the value of the demo command transmission timer is not “0” (S1187: No), the main CPU 300 shifts to the next step S1188.

  In S1188, main CPU 300 determines whether or not an error such as a communication error has occurred between main control board MS and its connection board. If an error has occurred (S1188: Yes), the main CPU 300 shifts to the processing of S1192. If no error has occurred (S1188: No), the main CPU 300 shifts to the next step S1189.

  In S1189, main CPU 300 generates demo command data and stores the generated demo command data in the transmission data storage area of main RAM 301. The stored demonstration command data is transmitted to the sub-control board SS in the data transmission process (command transmission process) of S127 shown in FIG. As a result, a video for demonstration is projected as a demonstration display from the projector device B2.

  Next, the main CPU 300 sets "0" to the demo command transmission flag (S1190).

  Next, the main CPU 300 sets "0" to the error flag (S1191). Thereafter, the main CPU 300 ends the demo command transmission process.

  In S1192, main CPU 300 sets the error flag to “1” and ends the demo command transmission processing. In this case, no demo display is performed because an error is occurring.

  According to the projector drift correction processing using the drift correction temperature table shown in FIG. 150 depending on whether or not the demonstration is being displayed, the temperature range in which the drift correction is invalid differs depending on whether or not the demonstration is being displayed. In addition, the temperature range that becomes invalid during the demonstration display becomes relatively wide, while the temperature range that becomes invalid other than during the demonstration display becomes relatively narrow or the temperature range itself becomes invalid. That is, the frequency of the drift correction is changed not only by the drift correction temperature but also by the demonstration display, and the frequency of the drift correction can be suppressed even when the state of the demonstration display becomes longer, so that the drift error accumulated for each drift correction can be obtained. As much as possible, the deterioration of the image quality of the image projected from the projector device B2 can be effectively suppressed.

  FIG. 152 shows the transition of the gaming state according to the sixteenth modification.

  As shown in FIG. 152, the gaming machine 1 as a pachislot machine has a plurality of gaming states, and the gaming states include, for example, a normal gaming state and a bonus gaming state (hereinafter referred to as “BB”). ), A chance zone (hereinafter referred to as “CZ”), an ART gaming state (hereinafter referred to as “ART”), and a chance time (hereinafter referred to as “CT”).

  For example, the normal gaming state is a gaming state in which a shift lottery to CZ, BB, or the like is performed according to an internal winning combination, and when the shift lottery is won, the game shifts to CZ, BB, or the like. In the normal game state, for example, an effect image is displayed using the front screen mechanism E1.

  BB is a gaming state in which a so-called regular bonus is repeatedly performed until the number of paid-out medals exceeds a predetermined number. The state shifts from CZ, ART, or CT according to an internal winning combination, and a normal gaming state according to a predetermined ending condition. In addition, the game state in which the number of ART games is added or the first hit of ART is performed, and if these lotteries are won, the number of ART games is added or the game is shifted to ART. For example, in the BB shifted from the normal gaming state or the CZ, an image for effect is displayed using the front screen mechanism E1, and in the BB shifted from the ART, an effect image is displayed using the reel screen mechanism F1. In the BB of the ART addition zone shifted from the CT and the CT, an effect image is displayed while appropriately switching the fixed screen mechanism D and the reel screen mechanism F1.

  The CZ shifts from the normal gaming state according to the internal winning combination, performs a transition lottery to ART, BB, or CT via the ART, and, when the transition lottery is won, the game shifts to ART, BB, or CT. State. In this CZ, for example, an effect image is displayed using the front screen mechanism E1.

  The ART refers to a state in which the sub CPU 400 informs the reel stop operation so that the player wins or non-wins the internal winning combination advantageously, and combines the AT with a so-called replay high probability state (RT). It is a game state controlled by. During the ART, the internal winning combination can be awarded so as to increase the number of obtained medals without reducing as much as possible. Therefore, as the number of ART games increases, more medals can be obtained. The ART shifts from BB, CZ, or CT according to the internal winning combination, and performs a shift lottery to BB or CT. When the transfer lottery is won, the ART shifts to BB or CT. In this ART, for example, an effect image is displayed using the fixed screen mechanism D. For example, in the case of transition from ART to CT, during a replay high probability state, a game is performed for the purpose of aligning a specific symbol combination, and if a lottery that can align the specific symbol combination is won, the ART is executed. And the number of CT sets can be added.

  In the CT, for example, although the winning probability of a small win such as a bell, a watermelon, a cherry, etc. does not change, any small win can be won depending on a so-called stop operation by a player regardless of an internal winning win. In the gaming state in which the reels are controlled, the maximum value of the number of sliding frames (the maximum number of sliding displays) is basically 1 for one or a plurality of reels during CT. Incidentally, the maximum value of the number of sliding frames is 4 in a game state other than CT. The CT shifts from the ART in accordance with the internal winning combination, while performing a lottery for shifting to the ART, an additional lottery for the number of ART games, and an additional lottery for the number of CT sets. When these lotteries are won, the process proceeds to ART. Or the number of ART games or CT sets. Such CT continues for the number of games added to the number of games as prescribed. In this CT, an effect image is displayed using the reel screen mechanism F1.

  As described above, at the start of each game state, the screen to be projected by the projector device B2 is appropriately switched. In particular, at the start of CT in which an image is projected on a specific screen (reel screen mechanism F1), the focus position is changed while performing drift correction after returning the focus position to the focus origin once. Has become. As a result, all the drift errors accumulated so far are removed. Therefore, for an image projected from the projector apparatus B2 while performing drift correction during the electric focus control, image quality deterioration due to drift correction can be effectively suppressed each time the CT shifts to CT.

  The plurality of gaming states are not limited to these, and may include, for example, a state in which the winning probability of shifting to CZ in the normal gaming state is high or a low probability. The game state may also include a state having a different probability of transition to a more advantageous game state.

  FIG. 153 shows a focus adjustment frequency setting table stored in the sub-ROM board 42 of the sub-control board SS as a table according to the seventeenth modification.

  As shown in FIG. 153, in the focus adjustment frequency setting table, according to the case where the frequency of change of the focus position is relatively high and the case where the frequency of change is relatively low, the number of symbol changes since the last time the focus position was adjusted (re-adjusted) When the number of times has reached, for example, 150 or 300 times, a setting change request is made to perform the next origin adjustment. The case where the frequency of change of the focus position is relatively high corresponds to, for example, during the CT described above with reference to FIG. 152, and the case where the frequency of change is relatively low means that the game state other than during the CT is in the game state. Equivalent to. During CT, there is a possibility that the BB in the ART addition zone may be won, so the frequency of changing the focus position is relatively high. In FIG. 153, as an example, it is determined whether or not to perform the origin adjustment (re-adjustment) on the condition of the number of symbol fluctuations. It may be defined so as to determine whether or not to perform the next origin adjustment on the basis of the number of executions of a specific effect from the winning of the role, or the elapsed time from the previous origin adjustment. Further, for example, in a gaming machine provided with a so-called pseudo BB, there is a case where the number of times of change is 150 or more during the BB, so that the change during the BB may be applied as a relatively high frequency.

  FIG. 154 is a flowchart showing the effect content determination processing of sub-control board SS according to the seventeenth modification. The process shown in FIG. 154 is a process using the focus adjustment frequency setting table of FIG. 153, and corresponds to a modified example of the process shown in FIG. 144, FIG. 146, or FIG.

  As shown in FIG. 154, the sub CPU 400 determines the effect content according to the command transmitted from the main CPU 300 of the main control board MS (S1201).

  Next, the sub CPU 400 determines whether or not the effect involves a change in the focus position that requires screen switching based on the determined effect contents (S1202). If the effect involves a change in the focus position (S1202: Yes), the sub CPU 400 proceeds to the process of S1208. If the effect does not involve a change in the focus position (S1202: No), the sub CPU 400 proceeds to the next process of S1203.

  In S1203, the sub CPU 400 acquires the value of the focus drift correction number counter as the number of drift corrections, and determines whether the number of drift corrections is, for example, 15 or more as a predetermined value. If the number of drift corrections is equal to or more than the predetermined value (S1203: Yes), the sub CPU 400 proceeds to the next step S1204. If the number of drift corrections is less than the predetermined value (S1203: No), the sub CPU 400 determines the effect content determined in the processing of S1201, and then proceeds to the processing of S1209.

  In S1204, the sub CPU 400 determines whether or not the internal winning combination is a specific small combination such as a rare small combination. If the internal winning combination is a specific small combination (S1204: Yes), the sub CPU 400 proceeds to the next step S1205. If the internal winning combination is not a specific small combination (S1204: No), the sub CPU 400 proceeds to the process of S1209.

  In S1205, the sub CPU 400 discards the effect content determined in the process of S1201, and changes the effect content to an effect corresponding to the winning of a specific small role with a change in the focus position.

  Next, the sub CPU 400 sets the focus origin adjustment flag to “ON” (S1206).

  Next, the sub CPU 400 sets −1 as an initial value in the focus drift correction number counter (S1207).

  Then, as an effect changed in the process of S1205, the sub CPU 400 requests the focus position setting change request in order to project the image while changing the focus position while performing the drift correction after temporarily returning the focus position to the focus origin. Is performed (S1208). As a result, as the effect image projected from the projector device B2, for example, as shown in FIG. 145 (a), once the focus position returns to the focus origin, so-called out-of-focus occurs and corresponds to a specific small role. The image becomes difficult to see, and thereafter, as shown in FIG. 145 (b), by gradually adjusting the focus position to a position corresponding to the screen to be projected, a symbol corresponding to a specific small role can be clearly seen. Such an image is displayed.

  Next, the sub CPU 400 determines whether or not the gaming state is a bonus (BB) (S1209). When the gaming state is the bonus (BB) (S1209: Yes), the sub CPU 400 proceeds to the next step S1210. If the gaming state is not the bonus (BB) (S1209: No), the sub CPU 400 shifts to the next step S1212.

  In S1210, sub CPU 400 further determines whether or not the effect mode is the effect mode of the ART addition zone during the bonus. In the effect mode in the BB of the ART addition zone, since the fixed screen mechanism D and the reel screen mechanism F1 are appropriately switched, the frequency (the number of times of change) of the focus position is relatively high (more frequently) than in other effect modes. )Become. Then, in the case of the effect mode of the ART addition zone during the bonus (S1210: Yes), the sub CPU 400 shifts to the next processing of S1211. If it is not the effect mode of the ART addition zone during the bonus (S1210: No), the sub CPU 400 proceeds to the process of S1212.

  In step S1211, the sub CPU 400 sets the focus change frequency to “high”. That is, reference is made to a case where the focus change frequency is “high” in the focus adjustment frequency setting table of FIG. 153. Thereby, when the symbol change number reaches 150 times since the previous adjustment of the origin of the focus position (re-adjustment) is performed, the sub CPU 400 once again returns the focus position to the focus origin by the readjustment, and then performs the drift correction. The video is projected while changing the focus position while performing. After that, the sub CPU 400 ends the effect content determination processing.

  On the other hand, in S1212, the sub CPU 400 sets the frequency of focus change to “low”. That is, reference is made to the case where the focus change frequency is “low” in the focus adjustment frequency setting table of FIG. With this, when the symbol change number reaches 300 times, which is more than the previous 150 times, after performing the origin adjustment (re-adjustment) of the focus position last time, the sub CPU 400 once again returns the focus position to the focus origin by the readjustment. Then, the image is projected while changing the focus position while performing drift correction. After that, the sub CPU 400 ends the effect content determination processing.

  According to the effect content determination processing using the focus adjustment frequency setting table of FIG. 153, in a specific game state (effect mode) in which the frequency of change of the focus position is relatively increased along with the switching of the screen, the change frequency is changed. The origin of the focus position is more likely to be adjusted than in the effect mode in other game states where the focus position is relatively small, so the focus adjustment error accumulated each time the focus position is changed is also reduced according to the focus position change frequency Therefore, it is possible to effectively suppress the deterioration of the image quality of the video due to the focus adjustment error.

  FIG. 155 shows a focus origin adjustment determination process by the sub CPU 400 of the sub control board SS as the process according to the eighteenth modification. The processing illustrated in FIG. 155 corresponds to a modified example of the processing illustrated in FIG. 143.

  As shown in FIG. 155, the sub CPU 400 determines whether or not to shift to a demonstration (at the time of receiving a demonstration command) (S1221). If it is time to shift to the demonstration (S1221: Yes), the sub CPU 400 shifts to the process of S1228. If it is not time to shift to the demonstration ((S1221): No), the sub CPU 400 shifts to the next process of S1222.

  In S1222, sub CPU 400 determines whether or not the game state is at the start of CT. When it is time to start CT (S1222: Yes), the sub CPU 400 proceeds to the process of S1228. If it is not time to start CT, the sub CPU 400 shifts to the next process of S1223.

  In S1223, sub CPU 400 determines whether or not the origin adjustment of the focus position has been selected by the setting in the member menu. When the origin adjustment of the focus position is selected by the member menu (S1223: Yes), the sub CPU 400 proceeds to the process of S1228. When the origin adjustment of the focus position is not selected by the member menu, the sub CPU 400 shifts to a process of the next S1224.

  In S1224, the sub CPU 400 acquires the value of the focus drift correction number counter as the number of drift corrections, and determines whether or not the number of drift corrections is, for example, 30 or more as a predetermined value. When the number of times of drift correction is equal to or more than the predetermined value (S1224: Yes), the sub CPU 400 proceeds to the process of S1225. When the number of times of drift correction is less than the predetermined value (S1224: No), the sub CPU 400 proceeds to the process of S1226.

  In S1225, sub CPU 400 sets −1 as an initial value in the focus drift correction number counter. After that, the sub CPU 400 shifts to the process of S1228.

  In S1226, sub CPU 400 determines whether or not a condition according to the focus position change frequency, that is, a predetermined condition according to the focus position change frequency defined in the focus adjustment frequency setting table in FIG. 153 is satisfied. . For example, when the frequency of changing the focus position is “high”, the number of symbol changes reaches 150 times since the last time the focus position was adjusted, or the frequency of changing the focus position is “low” If the number of symbol changes has reached 300 since the origin adjustment of the focus position was performed last time (S1226: Yes), the sub CPU 400 shifts to the next process of S1227. On the other hand, even if the frequency of change of the focus position is “high”, if the previous origin adjustment or the number of symbol changes has not reached 150 times, or if the frequency of change of the focus position is “low,” If the number of symbol changes has not reached 300 (S1226: No), the sub CPU 400 ends the focus origin adjustment determination process.

  In step S1227, the sub CPU 400 clears the value of the change frequency counter that counts the number of changes in the focus position when the focus origin adjustment flag is in the “OFF” state.

  Next, the sub CPU 400 sets the focus origin adjustment flag to “ON” (S1228).

  Next, the sub CPU 400 issues a focus position setting change request to change the focus position while performing drift correction after temporarily returning the focus position to the focus origin (S1229). In this processing, the sub CPU 400 stores the setting change request data including the origin adjustment of the focus position in the sub device transmission storage area of the sub RAM board 41, and transmits this data to the projector device B2. The focus position setting change request data includes the content of changing the focus position after returning the focus position to the focus origin. Thus, for example, when the screen on which the image is to be projected is switched, the projector device B2 controls the focus mechanism 242 based on the focus position setting change request data, thereby temporarily returning the focus position to the focus origin, respectively. The focus of the projection lens 210 can be adjusted while performing drift correction to a focus position corresponding to the screen. After that, the sub CPU 400 ends the focus origin adjustment determination process.

  According to such focus origin adjustment determination processing, the condition for adjusting the focus position origin is switched in accordance with the frequency of change of the focus position, and the focus adjustment error can be appropriately reduced. Image quality degradation can be effectively suppressed.

In such a communication sequence, in response to a status request command transmitted from the sub CPU 400 to the control LSI 230, when a control command that does not indicate a correct reception result is transmitted from the control LSI 230, for example, the command is correct up to ten times. Until the reception result is indicated, the reception confirmation command is retransmitted by the retry process.

  FIG. 160 is a diagram showing a communication sequence at the time of screen switching between the projector device B2 and the sub CPU 400 according to the nineteenth modification. The screen switching here means after the screen to be projected is changed from one screen to another screen.

  As shown in FIG. 160, at the time of screen switching, the control LSI 230 of the projector device B2 transmits a command for requesting a parameter to the sub CPU 400 of the sub control board SS. The sub CPU 400 that has received the command for requesting the parameter transmits a command for setting the electric focus position offset to the control LSI 230. According to the command of the electric focus position offset setting, as shown in FIG. 161, the value of the electric focus position offset held in the sub CPU 400 (EEPROM 231) is set as the setting information of the corresponding screen after the change. As a result, the focus position is offset-adjusted with respect to the changed focus origin of the screen. The control LSI 230 that has received the electric focus position offset setting command transmits a reception confirmation command to the sub CPU 400.

  Next, the sub CPU 400 transmits a command for setting the horizontal image position offset to the control LSI 230. According to the horizontal image position offset setting command, as shown in FIG. 161, the value of the horizontal image position offset held in the sub CPU 400 (EEPROM 231) is set as the setting information of the corresponding screen after the change. . As a result, the horizontal image position is offset adjusted with respect to the screen after the change. The control LSI 230 that has received the horizontal image position offset setting command transmits a reception confirmation command to the sub CPU 400.

  Next, the sub CPU 400 transmits a command for setting a vertical image position offset to the control LSI 230. According to the vertical image position offset setting command, as shown in FIG. 161, the value of the vertical image position offset held in the sub CPU 400 (EEPROM 231) is set as the setting information of the corresponding screen after the change. . As a result, the vertical image position is offset adjusted with respect to the changed screen. The control LSI 230 that has received the vertical image position offset setting command transmits a reception confirmation command to the sub CPU 400. Although not shown in FIG. 160, the sub CPU 400 that has received the reception confirmation command transmits a setting completion command to the control LSI 230, and the control LSI 230 that has received the command transmits the reception confirmation command to the sub CPU 400 again. After that, the command of the parameter request is retransmitted to the sub CPU 400.

  Next, the sub CPU 400 transmits a command (see FIG. 161) of the status request “drift correction temperature” to the projector B2 to the control LSI 230. The control LSI 230 that has received the command of the status request “drift correction temperature” transmits the command indicating the drift correction temperature (see FIG. 161) to the sub CPU 400, using the temperature detected by the temperature sensor B25 as the drift correction temperature.

  Next, the sub CPU 400 transmits a command of completion of status request to the projector device B2 to the control LSI 230, and the control LSI 230 that has received the command transmits a command of reception confirmation to the sub CPU 400. Although not shown in FIG. 160, the control LSI 230 that has transmitted the command transmits the parameter request command (see FIG. 161) again to the sub CPU 400.

  After that, the sub CPU 400 that has received the command for requesting the parameter transmits a command for commanding electric focus drift correction to the control LSI 230. As a result, in the projector device B2, the focus position offset adjusted with respect to the focus origin is further compensated and adjusted by drift correction based on the drift correction temperature indicated by the above-mentioned command. Then, the control LSI 230 transmits a reception confirmation command to the sub CPU 400, and the sub CPU 400 that has received the reception confirmation command transmits a setting completion command to the control LSI 230, and the control LSI 230 that has received the command confirms the reception confirmation. Is transmitted to the sub CPU 400. Thereby, the communication sequence at the time of screen switching ends.

  As described above, the communication sequence at the time of screen switching is performed as one set of the procedure shown in FIG. 160 when the screen to be projected is changed. In such a communication sequence, when a control command that does not indicate a correct reception result is transmitted from the control LSI 230 to the sub CPU 400, for example, the reception check command is retried up to ten times until a correct reception result is indicated. Is resent.

  According to such a communication sequence, each time the screen is switched, the focus position is offset-adjusted, and the focus position is also adjusted with high accuracy by drift correction according to the temperature. Frequent adjustments can also suppress disturbance of the image and deterioration of the image quality, and can continuously project a high-quality image while switching screens.

  In addition, since the horizontal and vertical positions of the image to be projected are also adjusted each time the screen is switched, it is necessary to project the image from the projector device B2 to the appropriate horizontal and vertical projection position for each screen. This makes it possible to perform image correction physically and software-wise.

  Further, although the focus position is adjusted depending on the temperature condition of the projector device B2 although the offset adjustment is performed, a predetermined time for acquiring the temperature from the projector device B2 is required to perform the drift correction at the time of screen switching. . That is, depending on the predetermined time, the screen may be switched while the temperature is obtained from the projector device B2. On the other hand, according to the communication sequence at the time of the screen switching described above, the offset adjustment of the horizontal image position and the vertical image position is performed after the offset adjustment of the focus position, and then the focus position is readjusted by drift correction. The drift correction is finally performed in a step-by-step procedure, so that the screen switching operation is frequently performed, while suppressing the disturbance of the image with high accuracy. High-quality images can be continuously projected.

  FIG. 162 shows a main control main process executed on the main control board of the pachinko machine according to the twentieth modification.

  In the pachinko machine, when the power is turned on, first, the main CPU of the main control board performs an initial setting process (S1231). In this process, the main CPU performs, for example, a process of permitting access to the main RAM, restoring a backup, initializing a work area, and the like. Next, the main CPU performs an update process of the initial value random number (S1232). In this process, the main CPU updates the initial random number counter value.

In this process, the main CPU controls the display of the first special symbol, the second special symbol, and the variable display of the normal symbol based on the execution results of the special symbol control process and the ordinary symbol control process.

  Next, the main CPU performs a game information data generation process (S1236). In this process, the main CPU generates game information data to be transmitted to a hall computer or the like of the game store, and stores the game information data in the main RAM.

  Next, the main CPU performs storage / game state data generation processing (S1237). In this process, the main CPU generates storage / game state data to be transmitted to the sub-control board of the pachinko machine based on the value of the probable change flag and the value of the time reduction flag, and stores the storage / game state data in the main RAM. I do. After that, the main CPU returns to the process of S1232, and repeats the above-described processes from S1232.

  FIG. 163 shows a system timer interrupt process executed on the main control board of the pachinko machine according to the twentieth modification.

  In a pachinko gaming machine, the main CPU interrupts the main process at a predetermined cycle and executes a system timer interrupt process even during the execution of the main process. Specifically, the main CPU executes a system timer interrupt process as shown in FIG. 157 according to a clock pulse generated at a predetermined cycle (for example, 2 ms) from the reset clock pulse generation circuit.

  As shown in FIG. 157, the main CPU saves the data (information) of each register (S1241). Next, the main CPU performs a random number update process (S1242). In this process, the main CPU updates various random numbers extracted from the big hit determination counter, the symbol determination counter, the hit determination counter, the fall determination counter, the variation pattern determination counter, the effect pattern determination counter, and the like. .

  It should be noted that the jackpot determination counter and the symbol determination counter lack fairness if the counter value update timing is indefinite. Therefore, the big hit determination counter and the symbol determination counter update at a periodic timing of, for example, 2 ms in order to ensure fairness.

  Next, the main CPU performs a switch input detection process (S1243). In this process, the main CPU detects winning or passing to various starting ports, various winning ports, and a ball passage detector.

  Next, the main CPU performs a timer update process (S1244). Specifically, the main CPU includes various timers such as a waiting time timer for synchronizing the main control board and the sub control board, and a special winning opening time timer for measuring the opening time of the special winning opening. Perform update processing.

Next, the main CPU performs a command output process (S1245). In this process, the main CPU transmits various commands such as a winning command, a fluctuation command, and a demo command to the sub CPU of the sub control board. For example, a demo command is transmitted when a predetermined time elapses without firing of a game ball after the end of the change of the special symbol.
(For example, it is transmitted when the state in which the game is not performed continues for 3 minutes or more.

  Next, the main CPU performs a game information output process (S1246). In this processing, the main CPU outputs various information related to the game processed by the main control board, the sub control board, the payout / launch control circuit, and the like to a hall computer or the like of the game store.

  Next, the main CPU restores the data of each register saved in S1241 (S1247). After that, the main CPU ends the system timer interrupt processing.

  Even in such a pachinko machine, by mounting the projector device B2 and the like, the same effect as the above-described pachislot machine can be exhibited.

  Note that the present invention is not limited to the above embodiment. In the above-described embodiment, a pachislot machine and a pachinko machine have been described as typical examples of the gaming machine, but the present invention is not limited to this. The various techniques of the present invention described above can be applied to other game machines, and can be applied to, for example, enclosed game machines. In addition, general-purpose technology can be applied to various gaming machines such as gaming machines and slot machines in addition to the gaming machines mentioned above.

  Further, the numerical values, information, components, and the like shown in the above embodiments are merely examples, and it goes without saying that they can be appropriately changed within the scope of the present invention. For example, a value or a number may include 0, and may include a minus or plus value.

  For example, in the present embodiment, various conditions include the number of counts and the number of times of execution, and there is a process of determining the number of times of execution and the execution time (execution period), which is the period of execution. It is not something to be done. For example, in the case where the execution is performed three or more times, the execution may be performed one or more times or zero or more times depending on the initial value. This is because, as a predetermined condition, the number of executions is determined to be three or more. When it is determined whether or not the execution has been performed three or more times, basically, from a software viewpoint, whether or not the execution has been performed is determined. Since it is only necessary to be able to make the determination, the condition is to determine whether it is 1 or 0 in information theory (code theory). Conversely, the same applies to the case where it is determined whether or not execution has been performed. In information theory (code theory), it is determined whether the value is 0 or 1.

  In other words, determining whether or not execution has been performed is equivalent to determining whether the binary value corresponding to the execution unit is 1 or 0. In this case, when the execution is performed, the flag is set to “ON”, and the flag is set to “ON”. Even when it is determined whether or not the signal is “ON”, as a result, it is determined whether or not there is a signal input that sets the flag to “ON” (whether or not the signal is received once or more times, (E.g., whether or not there is an output). Therefore, even when determining the presence or absence of a flag, the number of executions is not counted, but is equivalent to determining the number of executions (the number of counts, the count result, the number of interrupts, etc.) as a unit. The determination of the flag and the determination of the number of times can be executed by essentially the same comparison operation processing.

  The same applies to the case of determining the time. For example, the determination of the execution time is synonymous with determining whether the binary value corresponding to the execution time is 1 or 0. And can be executed by a simple comparison operation. However, when a determination is made using a flag or a variable, it may be determined that there is a value when the value is 0 and to be absent when the value is 1 by negative logic.

  Further, at the time of starting the gaming machine, for example, in order to prevent an afterimage phenomenon from occurring in the sub liquid crystal display device, the pack light may be turned off until communication is established.

  Further, at the time of error notification, since the movable screen is not returned to the standby position, an image of the error notification may be projected in accordance with the screen to be projected at that time.

  Further, the projector device of the present embodiment is configured to be able to perform projection on a plurality of screens, but is not limited to this, and as the projector device, one screen or a plurality of screens may be used. What is necessary is just to be able to project onto any screen. In addition, the projection target is not limited to the screen, for example, an accessory, a board, a front panel, an outer frame, a body frame, a cabinet, an upper plate, a lower plate, a player, a ceiling above the gaming machine, a passage from the gaming machine to the passage. Various projection forms such as projection toward the target are conceivable. Also, as the projection method, for example, various methods such as a so-called rear project evening, a front project evening, a rear projector that reflects projection light, a front projector that reflects projection light, and the like can be applied. It is also possible to combine a plurality of these different methods.

  In addition, the intake fan and the exhaust fan in the present embodiment are ventilation means capable of ventilating the inside of the projector device by rotating their components. That is, the ventilation means includes an intake means or an exhaust means, and the control (shutdown, warning condition, etc.) for the intake means in the present embodiment is also applicable to the exhaust means, The control can also be applied to the intake means.

  Based on the above embodiment, the outline of the present invention will be listed below as supplementary notes.

Description of the Related Art Some conventional gaming machines use a projector (projection device) instead of a liquid crystal display device for displaying a video for a game or the like (for example, JP-A-6-35066 and JP-A-2009-240559). reference). In such a gaming machine, an image is projected from a projector onto a projection surface such as a screen.

2. Description of the Related Art Some conventional gaming machines use a projector (projection device) instead of a liquid crystal display device for displaying a video for a game or the like (for example, JP-A-6-35066 and JP-A-2009-240559). reference). In such a gaming machine, an image is projected from a projector onto a projection surface such as a screen.

  However, in the above-described conventional gaming machine, the angle of view may be greatly shifted each time the screen (projection surface) is switched, and the appearance of the projected image may gradually change with the game.

  The present invention has been made in view of the above points, and provides a gaming machine capable of projecting an image at an appropriate position by switching a projection surface, and eliminating discomfort of the image. The purpose is to do.

  In order to achieve the above object, the present invention provides the following gaming machines.
