[Function flow]
A pachislot machine as a gaming machine according to an embodiment of the present invention will be described with reference to the drawings. First, a functional flow according to the embodiment of the gaming machine will be described with reference to FIG.

  In the pachislot machine of the present embodiment, medals are used as game media for playing games. In addition to the medals, coins, game balls, game point data, tokens, or the like can be applied as game media.

  When a player inserts a medal and operates the start lever, one value (hereinafter, random number value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal winning combination determining means performs lottery based on the extracted random number value and determines the internal winning combination. That is, when the start lever is operated, the internal winning combination determining means determines an internal winning combination with a predetermined winning probability from among a plurality of combinations, assuming that a predetermined start condition is satisfied. The internal winning combination determining means is a main control circuit described later. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations include those related to “winning” in which benefits such as paying out medals, re-games, bonuses, etc. are given to players, and other so-called “loses”. Is provided.

  Further, when the start lever is operated, a plurality of reels are rotated. Thereafter, when the player presses the stop button corresponding to the predetermined reel, the reel stop control means stops the rotation of the corresponding reel based on the internal winning combination and the timing when the stop button is pressed. Control to stop the fluctuation of the symbol. The reel stop control means is responsible for a main control circuit and a stepping motor which will be described later.

  In the pachislot machine, basically, control is performed to stop the rotation of the corresponding reel within a specified time (190 msec or 75 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding symbols”. When the specified time is 190 msec, the maximum number of sliding symbols is set to 4 symbols, and when the specified time is 75 msec, the maximum number of sliding symbols is set to 1 symbol.

  When the internal winning combination allowing the symbol combination display related to winning is determined, the reel stop control means usually displays the symbol combination within the specified time of 190 msec (four symbols) for the winning determination line. The rotation of the reel is stopped so as to display as much as possible. In addition, the reel stop control means uses various specified times corresponding to the gaming state to rotate the reels so that combinations of symbols that are not permitted to be displayed by the internal winning combination are not displayed along the winning determination line. Stop.

  The winning determination means is based on the combination of symbols stopped on the winning determination line based on the fact that the reel stop control means stops the rotation of the plurality of reels and the change in the symbols is stopped. Judge the winning. This winning determination means is carried out by a main control circuit described later. When the winning determination means determines that the winning combination is a prize, a privilege such as a medal payout is given to the player. In a pachislot machine, a series of flows as described above is performed as one game.

  Also, in the pachislot machine, in the series of flows described above, video display performed by an image display device such as a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, or a combination thereof is used. Various productions are performed.

  When the start lever is operated, an effect random number value (hereinafter referred to as effect random number value) is extracted separately from the random number value used for determining the internal winning combination. When the effect random number value is extracted, the effect content determining means determines, by lottery, what is to be executed this time from among a plurality of types of effect contents associated with the internal winning combination. This effect content determination means is carried out by a sub-control circuit described later.

  When the contents of the effect are determined, the effect executing means executes the corresponding effect in conjunction with each opportunity, such as when the rotation of the reels starts, when the rotation of each reel stops, or when determining whether there is a winning. As described above, in the pachislot machine, the player has an opportunity to know or predict the determined internal winning combination (in other words, a combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. The player's interest can be improved.

[Pachislot machine structure]
Next, the external structure of the pachislot machine according to the present embodiment will be described. In the following description, the side (direction) from the pachislot machine 1 toward the player is referred to as the front side (front direction) of the pachislot machine 1, and the opposite side to the front side is referred to as the rear side (rear direction, depth direction). The right side and the left side as viewed from the player are referred to as the right side (right direction) and the left side (left direction) of the pachislot machine 1, respectively. The direction including the front side and the rear side is referred to as the front-rear direction or the thickness direction, and the direction including the right side and the left side is referred to as the left-right direction or the width direction.

  As shown in FIG. 4, the upper door mechanism UD and the lower door mechanism DD are formed so as to correspond to the shape and size of the opening of the cabinet G. The upper door mechanism UD and the lower door mechanism DD are provided so that the upper part and the lower part of the opening in the cabinet G can be closed. The upper door mechanism UD has an upper display window UD1 at the center. The upper display window UD1 is provided with a transparent panel UD11 that transmits light.

  As shown in FIG. 5, the cabinet G is partitioned into an upper space and a lower space by an intermediate support plate G1. That is, the intermediate support plate G1 functions as a partition plate that partitions the cabinet G into an upper space and a lower space. The upper space is a space on the rear side of the upper door mechanism UD in the cabinet G and accommodates the display unit A and the like. The lower space is a space on the rear side of the lower door mechanism DD in the cabinet G, and accommodates the reel unit RU, the main control board MS that controls the operation of the entire pachislot machine 1, and the like.

<Display unit A>
As shown in FIG. 6, the display unit A is placed on the intermediate support plate G1 in the cabinet G so as to be replaceable. As shown in FIG. 7, the display unit A is a so-called projection mapping apparatus having a projection unit B that projects an image and a screen unit C that displays an image projected from the projection unit B.

  Here, the projection mapping device is for projecting an image on the surface of a three-dimensional object such as a building or a natural object. Etc.) and an image corresponding to the production information generated based on the shape is projected, thereby enabling an advanced and powerful production.

  The display unit A has a housing A1 with an opening formed in the front. The casing A1 includes a projector cover B1 as a projection casing of the projection unit B and a screen casing C10 of the screen unit C. Although details will be described later, the screen casing C10 has a box shape having a bottom plate C1, a right side plate C2, a left side plate C3, and a back plate C4. The projector cover B1 is replaceably attached to the upper surface of the screen casing C10.

<Screen unit C>
The screen unit C constitutes a screen device on which the effect image projected from the projection unit B is displayed. As shown in FIG. 8, the screen unit C has a screen casing C10.

  Specifically, the screen casing C10 includes a horizontally arranged bottom plate C1, a right side plate C2 erected at the right end portion of the bottom plate C1, a left side plate C3 erected at the left end portion of the bottom plate C1, and the bottom plate C1. And a back plate C4 erected on the rear end. 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 upper side where the projection unit B is located are opened. A box-shaped screen casing C10 is formed.

  Inside the screen casing C10, a fixed screen D, a front screen E1, and a reel screen F1 are provided. The fixed screen D has a front reflection part D1, a right reflection part D2, a left reflection part D3, and a lower reflection part D4, and is attached to the screen casing C10 at a fixed exposure position where an image projected from the projection unit B is displayed. It is fixed.

  The front screen E1 has a front standby position arranged on the upper side, which is in a standby posture in which display of the image projected from the projection unit B is prohibited, and an exposure posture in which display of the image projected from the projection unit B is permitted. And is held by the screen casing C10 so as to be rotatable with respect to the front exposure position arranged on the lower side. The front exposure position is a position where an image projected from the projection unit B is displayed, and is set to be ahead of the fixed exposure position.

  Therefore, when the front screen E1 is moved to the reel exposure position, the front screen E1 covers the fixed screen D from the front, so that the image projected from the projection unit B is displayed only on the front screen E1. Is done.

  The reel screen F1 is held by the screen casing C10 so as to be rotatable between a reel exposure position and a reel standby position. The reel exposure position is set so that the image projected from the projection unit B is displayed and exists ahead of the fixed exposure position.

  For this reason, when the reel screen F1 is moved to the reel exposure position, the reel screen F1 covers the fixed screen D from the front, leaving the lower surface reflection portion D4 of the fixed screen D, thereby covering the projection unit B. Are projected on the reel screen F1 and the lower surface reflection portion D4. Note that an image projected from the projection unit B may be displayed only on the reel screen F1 or only on the lower surface reflection portion D4 of the fixed screen D depending on the configuration of the image.

  When the reel screen F1 moves to the reel standby position, the image projected from the projection unit B is displayed on the fixed screen D by exposing the fixed screen D.

  A screw B112 is passed through the angle adjustment hole B111 of the reflector holding part B11 from the front side. The angle adjustment hole B311 of the mirror holder B31 is formed in an inner screw shape (a so-called tap) that receives a thread of the screw B112 passed through the angle adjustment hole B111.

  For this reason, when the screw B112 passed through the angle adjustment hole B111 is rotated in a loosening direction with respect to the angle adjustment hole B311, the distance between the reflector holding part B11 and the mirror unit B3 increases. On the other hand, when the screw B112 passed through the angle adjustment hole B111 is rotated in a direction to be tightened with respect to the angle adjustment hole B311, the distance between the reflector holding portion B11 and the mirror unit B3 is reduced.

  Further, the screw B112 through which the angle adjusting hole B111 is passed is configured by a spring adjusting screw with a coil spring fitted thereto, and is biased by the coil spring toward the reflector holding portion B11 side, thereby stabilizing the adjustment position of the reflector holding portion B11.

The inclination (yaw angle) on the plane can be adjusted.

  As shown in FIGS. 11 and 12, the main body 2200 and the rear end 2202 of the upper pedestal B220 are provided with three connection holes 2200A for connecting the lower pedestal B221. These three connecting holes 2200 </ b> A are arranged so as not to be positioned on the same straight line in a plane (horizontal plane) along the main body 2200.

  The lower pedestal B221 is a sheet metal member that substantially corresponds to the main body 2200 and the rear end 2202 of the upper pedestal B220. Three connecting screw portions 2210 are integrally formed on the lower base B221 so as to protrude upward corresponding to the three connecting holes 2200A. These three connecting 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 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 B 223a. The lower pedestal B221 is connected to the lower surface of the upper pedestal B220 while supporting the under cover B223 via the case B22 and the stay B223a.

  The upper pedestal B220 and the lower pedestal B221 are connected to each other at three connecting portions R1, R2, and R3 so that the distance between them can be adjusted.

  Each of the connecting portions R1, R2, and R3 includes a connecting screw portion 2210 of the lower pedestal B221 that passes through the connecting hole 2200A of the upper pedestal B220, a coil spring 2211, a washer 2212, and a nut 2213 (see FIG. 15).

  A mirror adjustment operation by the first adjustment device 100 according to the embodiment of the present invention configured as described above will be described with reference to FIG. The mirror adjustment operation described below is based on an execution instruction input to the input device of the control device 103 in a state where the projector cover B1 to which the mirror unit B3 is temporarily fixed is fixed to the first adjustment device 100. Be started.

  First, the control device 103 instructs the position sensor device 102 to perform measurement (S1). Specifically, the distance sensors 106a to 106c of the position sensor device 102 are caused to detect the position of the reflecting surface of the mirror unit B3.

  Next, the control device 103 determines whether or not each position detected by the distance sensors 106a to 106c is a predetermined position (S2). Specifically, the control device 103 determines that the difference calculated by the expressions (1) to (3) described later between the positions detected by the distance sensors 106a to 106c and a predetermined position is within the allowable error range. Judge whether there is.

  If it is determined that each position detected by the distance sensors 106a to 106c is a predetermined position (YES), the control device 103 advances the mirror adjustment operation to step S9.

  On the other hand, when it is determined that the positions detected by the distance sensors 106a to 106c are not predetermined positions (NO), the control device 103 fits the drivers 104a to 104c of the adjustment driver device 101 into the screws B112. Thus, the actuators 105a to 105c are controlled (S3).

  Next, the control apparatus 103 confirms whether each driver 104a-104c of the adjustment driver apparatus 101 fits in screw B112 (S4). Specifically, the control device 103 executes a tightening operation for tightening the screw B112 and a loosening operation for loosening the screw B112 with the drivers 104a to 104c of the adjustment driver device 101, and the detection values of the distance sensors 106a to 106c change. To check. When it is confirmed that the respective drivers 104a to 104c of the adjustment driver device 101 are fitted into the screws B112, the control device 103 executes a mirror unit adjustment process shown in FIG. 24 (S5).

  In the mirror unit adjustment process shown in FIG. 24, first, the control device 103 substitutes the detection values of the distance sensors 106a to 106c into SensA_dist, SensB_dist and SensC_dist, and the difference between SensA_dist, SensB_dist and SensC_dist and a predetermined position. Is extracted (S20).

  In the hard disk device of the control device 103, the target values MasterData_SensA, MasterData_SensB, and MasterData_SensC of the detection values of the distance sensors 106a to 106c are stored in advance.

  The control device 103 calculates the differences SensA, SensB, and SensC between SensA_dist, SensB_dist, and SensC_dist and MasterData_SensA, MasterData_SensB, and MasterData_SensC based on the following equations (1) to (3), respectively.

SensA = SensA_dist−MasterData_SensA (1)
SensB = SensB_dist−MasterData_SensB (2)
SensC = SensC_dist−MasterData_SensC (3)

  Next, the control device 103 calculates the tilt angle and position of the mirror unit B3 (S21). The hard disk device of the control device 103 includes a line segment that connects the design distance Mirror_SensorDist_X between the mounting position of the distance sensor 106b and the mounting position of the distance sensor 106c and the mounting position of the distance sensor 106b and the distance sensor 106c. And a design distance Mirror_SensorDist_Y between the distance sensor 106a and the distance sensor 106a are stored in advance.

  The control device 103 uses the differences SensA, SensB and SensC calculated by the above equations (1) to (3), the design distance Mirror_SensorDist_X, the inclination angle skew_x in the width direction of the mirror unit B3, the differences SensA, SensB and SensC, and The inclination angle skew_y in the height direction from the design distance Mirror_SensorDist_Y and the distance dist of the mirror unit B3 relative to the reference position from the differences SensA, SensB, and SensC are calculated based on the following equations (4) to (6), respectively. .

  Next, the control device 103 calculates the difference between the tilt angle and distance of the mirror unit B3 and each target value (S22). The hard disk device of the control device 103 includes a design target value Mirror_Skew_X_AdjTarget for the tilt angle in the width direction of the mirror unit B3, a design target value Mirror_Skew_Y_AdjTarget for the tilt angle in the height direction of the mirror unit B3, and A design target value Mirror_Height_AdjTarget of the distance of the mirror unit B3 with respect to the reference position is stored in advance.

  The control device 103 determines the difference skew_x_diff between the skew_x calculated by the equation (4) and the design target value Mirror_Skew_X_AdjTarget of the tilt angle in the width direction of the mirror unit B3, the skew_y calculated by the equation (5), and the mirror unit B3. The difference skew_y_diff from the design target value Mirror_Skew_Y_AdjTarget of the inclination angle in the height direction of the head and the difference dist_diff between the dist calculated by Expression (6) and the design target value Mirror_Skew_X_AdjTarget of the height of the mirror unit B3 are as follows: It calculates based on the formulas (7) to (9).

skew_x_diff = skew_x−Mirror_Skew_X_AdjTarget (7)
skew_y_diff = skew_y−Mirror_Skew_Y_AdjTarget (8)
dist_diff = dist−Mirror_Height_AdjTarget (9)

  Next, the control device 103 determines a pulse that is the driving amount of each actuator 105a to 105c from the difference between the tilt angle and distance of the mirror unit B3 calculated by the equations (7) to (9) and the target value in each design. The number is calculated (S23). The hard disk device of the control device 103 includes a value of a design distance Mirror_ScrewDist_X between the mounting position of the driver 104b and the mounting position of the driver 104c, a line segment connecting the mounting positions of the driver 104b and the driver 104c, and the driver 104a. The design distance between Mirror_ScrewDist_Y, the value of the pitch Mirror_ScrewPitch of the screw B112 passed through the driver 104a to driver 104c or the angle adjustment hole B111, and the actuator 105a required to rotate the driver 104a to driver 104c once. The number of pulses Mirror_MotorPulseRatio of ~ 105c is stored in advance.

  The control device 103 drives the driver 104a based on the equation (10) from skew_y_diff calculated by the equation (8), the distance Mirror_ScrewDist_Y, the number of pulses Mirror_MotorPulseRatio for rotating the driver 104a once, and the screw pitch Mirror_ScrewPitch. The number of pulses Pulse_A of the drive signal output to the actuator 105a is calculated.

  The control device 103 sets skew_x_diff calculated by Expression (7), skew_y_diff calculated by Expression (8), dist calculated by Expression (9), distance Mirror_ScrewDist_X, distance Mirror_ScrewDist_Y, and driver 104a to 1 Based on the formulas (11) and (12), the pulse numbers Pulse_B and Pulse_C of the drive signals output to the actuators 105b and 105c to drive the drivers 104b and 104c are calculated from the number of pulses Mirror_MotorPulseRatio and the screw pitch Mirror_ScrewPitch. To do.

  Next, the control device 103 outputs drive signals representing the pulse numbers Pulse_A, Pulse_B, and Pulse_C calculated by the equations (10) to (12) to the actuators 105a to 105c, respectively (S24), and ends the mirror unit adjustment processing. To do.

  In FIG. 23, the control device 103 determines whether or not each position detected by the distance sensors 106a to 106c is a predetermined position as a result of the mirror unit adjustment process (S6). Specifically, the control device 103 determines that the difference calculated by the above formulas (1) to (3) with respect to each position detected by the distance sensors 106a to 106c and a predetermined position is within an allowable error range. It is judged whether it is in.

  When it is determined that each position detected by the distance sensors 106a to 106c is not a predetermined position (the difference is outside the allowable error range) (NO), the control device 103 executes the mirror unit adjustment process again. Then, the mirror adjustment operation is returned to step S5.

  On the other hand, when it is determined that each position detected by the distance sensors 106a to 106c is a predetermined position (the difference is within the allowable error range) (YES), the control device 103 causes each of the adjustment driver devices 101 to The actuators 105a to 105c are controlled so as to remove the drivers 104a to 104c from the screw B112 (S7).

  Next, the control device 103 instructs the position sensor device 102 to perform measurement, and determines whether or not each position detected by the distance sensors 106a to 106c is a predetermined position (S8).

  In this step, it is confirmed whether or not the respective positions detected by the distance sensors 106a to 106c are shifted by removing the drivers 104a to 104c of the adjustment driver device 101 from the screw B112. Specifically, the control device 103 determines that the difference calculated by the above formulas (1) to (3) with respect to each position detected by the distance sensors 106a to 106c and a predetermined position is within an allowable error range. It is judged whether it is in.

  When it is determined that each position detected by the distance sensors 106a to 106c is a predetermined position (the difference is within the allowable error range) (YES), the control device 103 indicates that the display device has been adjusted. Is displayed (S9).

  On the other hand, if it is determined that each position detected by the distance sensors 106a to 106c is not a predetermined position (the difference is outside the allowable error range) (NO), the control device 103 has failed to adjust the display device. A message to that effect is displayed (S10).

  After executing the process of step S9 or S10, the control device 103 causes the position sensor device 102 to end the measurement. That is, the position sensor device 102 is instructed to retract the distance sensors 106a to 106c (S11), and the mirror adjustment operation is terminated.

  If it is determined in step S8 of the mirror adjustment operation described above that each position detected by the distance sensors 106a to 106c is not a predetermined position (NO), the control device 103 performs the mirror adjustment operation step. You may make it return to S5 and you may make it return mirror adjustment operation to step S1.

  As described above, the first adjustment device 100 according to the embodiment of the present invention causes the adjustment driver device 101 to adjust the position and orientation of the mirror unit B3 based on the detection result of the position sensor device 102. While ensuring the accuracy of the position and orientation of the unit B3, it is possible to achieve uniformity in accuracy required for adjustment and suppression of manufacturing cost required for adjustment time.

  In addition, the first adjustment device 100 according to the embodiment of the present invention causes the position sensor device 102 to detect a plurality of positions on the reflection surface of the mirror unit B3, and causes the adjustment driver device 101 to detect the back surface of the reflection surface of the mirror unit B3. Since the plurality of positions are adjusted, the position and posture of the reflecting surface of the mirror unit B3 can be accurately detected, and the position and posture of the mirror unit B3 can be accurately adjusted.

  Further, in the first adjustment device 100 according to the embodiment of the present invention, each position of the back surface of the reflection surface detected by the position sensor device 102 and each position of the reflection surface adjusted by the adjustment driver device 101 are in the width direction. In addition, the control in the control device 103 can be simplified by matching each other in the height direction.

  In addition, the control apparatus 103 which performs the mirror unit adjustment process demonstrated with reference to FIG. 23 repeats step S5 and step S6, and adjusts each driver 104a-104c based on the result of distance sensor 106a-106c. The position and orientation of the mirror unit B3 are adjusted by so-called feedback control that changes the amount.

<Focus adjustment process P2>
In the focus adjustment step P2, the focal length of the projector mechanism B2 is adjusted by the second adjustment device 200.

  In the present embodiment, the focus adjustment step P2 is executed in a state where the projection unit B in which the projector mechanism B2 is attached to the projector cover B1 is attached to the screen unit C.

  As shown in FIG. 25, the projector mechanism B2 includes a projector control board B23, an optical mechanism B24, and a relay board CK as electrical components. The sub-control device SS (see FIG. 19) is connected to the projector mechanism B2 via the relay substrate CK. The sub-control device SS controls the projector control board B23 according to the effect operation of the screen and the accessory, and projects the effect image on the screen and the accessory via the optical mechanism B24.

  The projector control board B 23 includes a control LSI 230, an EEPROM (registered trademark) 231, a DLP (registered trademark) control circuit 232, and an LED driver 233. The optical mechanism B24 is a component disposed around the lens unit B21 (see FIG. 10), and includes an LED light source that emits light of R (red), G (green), and B (blue), DMD, and lens unit B21. The projection lens 210 is provided with a focus mechanism for adjusting the focus (not shown).

  The control LSI 230 controls the DLP control circuit 232 to project an image based on a command from the sub-control device SS. The control LSI 230 performs focus adjustment when projecting an image by controlling the focus mechanism and moving the projection lens 210 in the optical axis direction based on a command from the sub-control device SS. The EEPROM 231 stores a control program by the control LSI 230 and data related to setting / adjustment of the projector mechanism B2.

  The DLP system of the projector mechanism B2 mainly includes a DLP control circuit 232, an LED driver, an LED light source and a DMD of the optical mechanism B24.

  Under the control of the DLP control circuit 232, an image reflected in a predetermined direction by the DMD proceeds to the lens unit B21, passes through the projection lens 210, enters the mirror unit B3, and finally reflects by the mirror unit B3. This leads to the projection target. As a result, an image is projected onto a screen or an object to be projected, and an effect image corresponding to the effect is formed.

  In the present embodiment, the projector mechanism B2 is configured as a so-called DLP projector. In addition, the projector mechanism B2 increases the projection distance to the projection target by folding the image by the mirror unit B3, and makes the projection distance of the image as short as possible by, for example, setting the contrast ratio to 1000: 1. .

  Thereby, the display unit A provided with the projector mechanism B2 is configured to be cheaper and smaller, and is easily mounted in a limited space in the cabinet G of the pachislot machine 1.

  In the focus adjustment step P2, the control device 201 of the second adjustment device 200 shown in FIG. 26 is connected to the projector mechanism B2 via the relay substrate CK instead of the sub control device SS.

  As shown in FIG. 26, the second adjustment device 200 includes a control device 201 constituting test video output means for outputting a test video to be projected to the projector mechanism B2 to the projector mechanism B2, and a test video by the projector mechanism B2. Has a camera 202 that constitutes a photographing means for photographing the screen unit C onto which the image is projected, and a photographing position changing mechanism 203 that changes the photographing position of the camera 202.

  The control device 201 is configured by a general-purpose computer device similar to the control device 103 of the first adjustment device 100. That is, in the computer device, the computer device functions as the control device 201 when the CPU executes a program stored in the hard disk device.

  As described above, since the screen unit C includes the fixed screen D, the front screen E1, and the reel screen F1 (see FIG. 8), the camera 202 needs to change the focal length according to each screen. .

  However, since the second adjustment device 200 includes the shooting position changing mechanism 203 that changes the shooting position of the camera 202, it is not necessary to perform focal length adjustment control for adjusting the focal length of the camera 202. Therefore, even cameras with different focal length adjustment ranges and resolutions can be easily exchanged by adjusting the focal length first.

  In the photographing position changing mechanism 203, a rail member is arranged in a direction orthogonal to the screen unit C, and a pedestal to which the camera 202 can be attached is installed on the rail member. An actuator 204 such as a servo motor is attached to this pedestal.

  The control device 201 can move the camera 202 in the direction approaching the screen unit C and the direction away from the screen unit C by controlling the actuator 204.

  The control device 201 controls the front screen drive mechanism E2 and the reel screen drive mechanism F2, thereby changing the screen on which the test image projected by the projector mechanism B2 is displayed to the fixed screen D, the front screen E1, and the reel screen F1. Switch between.

  The control device 201 changes the shooting position of the camera 202 based on switching of the screen on which the test video is displayed. Specifically, the control device 201 controls the actuator 204 according to the screen on which the test video is displayed, and moves the camera 202, thereby moving the distance between the fixed screen D and the camera 202 and the front screen. The distance between E1 and the camera 202 is set to substantially the same distance.

  In the present embodiment, since the positions of the front screen E1 and the reel screen F1 with respect to the projector mechanism B2 are hardly changed in the state exposed to the projector mechanism B2, the control device 201 controls the projector with respect to the fixed screen D. The focal length A of the mechanism B2 and the focal length B of the projector mechanism B2 with respect to the front screen E1 are set.

  The control device 201 outputs to the projector mechanism B2 a test image that is at least partially projected on the display surfaces of the fixed screen D and the front screen E1.

  For example, as shown in FIG. 27, the control device 201 controls the test screen TD7, which is an image projected on the display area of the left-side reflection unit D3 (see FIG. 8), and the front reflection unit D1. In the test image TD4, which is an image projected in the upper left display area, in the test image TD1, which is an image projected in the center display area of the front reflector D1, and in the upper right display area of the front reflector D1 A test image TD3 that is a projected image, a test image TD6 that is a video projected within the display area of the right-side reflection part D2, and a video that is projected within a display area close to the center bottom surface of the front reflection part D1. A test image TD including seven images, that is, a test image TD2 and a test image TD5 that is an image projected in the display area of the lower surface reflection portion D4, is output to the projector mechanism B2.

  For example, as illustrated in FIG. 28, the control device 201 projects a test video TE including nine test images TE <b> 1 to TE <b> 9 that are projected into a nine-divided display area with respect to the front screen E <b> 28. Output to B2.

  The control device 201 constitutes an edge strength acquisition unit that acquires the strength of the edge of the image captured by the camera 202 by the screen unit C onto which the test video is projected. Specifically, the control device 201 acquires the edge strength of each video included in the test video, and calculates the edge strength of the test video based on the edge strength of each video. In order to execute the image processing for calculating the edge strength, the number of CCD pixels of the camera 202 is desirably 2 million pixels or more.

  The control device 201 constitutes a focal length detection unit that detects a focal length at which the calculated edge strength is maximized while changing the focal length of the projector mechanism B2. Specifically, the control device 201 performs coarse adjustment processing for setting the focal length roughly for the fixed screen D and the front screen E1, and fine adjustment for setting the focal length with high definition based on the result of the rough adjustment processing. The adjustment process is executed.

  In the coarse adjustment processing, the control device 201 changes the focal length of the projector mechanism B2 from a predetermined focal length to a long distance (+) direction away from the screen and a (−) direction close to the screen, while roughly changing the test image. The edge strength of each video included in is acquired.

  In the coarse adjustment process, for example, the control device 201 specifies the focal length by changing the focal length of the projector mechanism B2 stepwise from a predetermined focal length to a long distance direction and a short distance direction in designated units.

  The control device 201 generates a quadratic approximate curve representing the relationship between the edge strength and the focal length for each video included in the test video. The control device 201 specifies the focal length that maximizes the edge strength from each quadratic approximate curve generated for each video included in the test video.

  The control device 201 specifies the shortest focal length as the fine adjustment start position reference value among the focal lengths that maximize the edge intensity specified by the coarse adjustment processing for each video included in the test video.

  In the fine adjustment processing, the control device 201 is included in the test video while finely changing the focal length of the projector mechanism B2 from the focal length obtained by subtracting a predetermined fine adjustment start correction value from the fine adjustment start position reference value. Get the edge strength of each video.

  In the fine adjustment processing, for example, the control device 201 uses the fine adjustment start position reference value as a starting point of the focal length of the projector mechanism B2, and changes the focal length step by step in a specified unit in the long distance direction and the short distance direction. Specify the focal length.

  The control device 201 generates a quadratic approximate curve representing the relationship between the edge strength and the focal length for each video included in the test video. The control device 201 specifies the focal length that maximizes the edge strength from each quadratic approximate curve generated for each video included in the test video.

  The control device 201 performs weighting based on a weighting factor assigned to each video included in the test video with respect to the focal length that maximizes the edge strength specified for each video included in the test video. The focal length of the projector mechanism B2 is calculated by taking the average. The weighting coefficient is determined in advance so as to be set higher as the display area of each video included in the test video is more easily spotted by the player.

  In the present embodiment, the weighting factors Wtd1 to Wtd7 of the test images TD1 to TD7 for the fixed screen D are, for example, Wtd1 = 1.5, Wtd2 = 1.4, Wtd3 = 1.1, Wtd4 = 1.1. , Wtd5 = 0.8, Wtd6 = 0.8, Wtd7 = 1.0, and the focus in the central area of the fixed screen D is emphasized.

  Further, the weighting factors Wte1 to Wte9 of the test images TE1 to TE9 for the front screen E1 are, for example, Wte1 = 0.8, Wte2 = 1.1, Wte3 = 0.8, Wte4 = 1.2, Wte5 = 1. .5, Wte6 = 1.3, Wte7 = 0.9, Wte8 = 1.3, Wte9 = 0.9, and the focal point of the central area of the front screen E1, and then the focal area of the lower area close to the player Is emphasized.

  The control device 201 constitutes a focal length storage unit that stores the focal length calculated by the weighted average in the EEPROM 231 as a storage medium as the focal length on the screen.

  The focal length setting operation by the second adjustment device 200 according to the embodiment of the present invention configured as described above will be described with reference to FIG. The focal length setting operation described below is executed when the projector mechanism B2 is temporarily fixed to the projection unit B and the projection unit B is temporarily assembled to the screen unit C, and is input to the input device of the control device 201. Started based on instructions.

  First, the control device 201 controls the actuator 204 so that the camera 202 moves to the front screen shooting position when the test video is displayed on the front screen E1 (S30).

  Next, if the front screen E1 is not at the front exposure position, the control device 201 controls the front screen drive mechanism E2 so that the front screen E1 moves to the front exposure position (S31).

  Next, the control device 201 changes the focal length of the projector mechanism B2 to a predetermined initial reference focal length of the front screen E1, and projects a test image for the front screen E1 on the projector mechanism B2 (S32). Here, the initial reference focal length of the front screen E1 is temporarily stored as an initial value when the projector mechanism B2 is manufactured.

  Next, the control device 201 executes the coarse adjustment process shown in FIG. 30 on the front screen E1 (S33), and executes the fine adjustment process shown in FIG. 31 on the front screen E1 (S34).

  In FIG. 30, the control device 201 reads, from the hard disk device, the value of the adjustment start position FCS_Start, the value of the adjustment width FCS_Step_Len, the value of the number of adjustments FCS_Step_Num, and the like as parameters for the coarse adjustment processing (S40). The hard disk device of the control device 201 stores FCS_Start values, FCS_Step_Len values, and FCS_Step_Num values for coarse adjustment processing in advance.

  Here, the control device 201 acquires edge strength for each image included in the test image while changing the focal length of the projector mechanism B2 based on the adjustment start position FCS_Start, the adjustment width FCS_Step_Len, and the number of adjustments FCS_Step_Num. To do.

  That is, the control device 201 controls the focal length of the projector mechanism B2 based on the adjustment start position FCS_Start, the adjustment width FCS_Step_Len, and the adjustment count FCS_Step_Num so that the focal length changes to FCS_Start + FCS_Step_Len × (adjustment count−1) (S41). The edge strength for each video included in the test video is acquired (S42). Note that the edge strength for each video can be acquired by an image processing system (not shown) that processes a captured image of the camera 202 connected to the control device 201.

  When the edge strength corresponding to the adjustment count FCS_Step_Num is acquired for each video included in the test video, the control device 201 sets the focal length corresponding to the adjustment count as the Y axis, and the edge strength for each video included in the test video. A quadratic approximate curve with X as the X axis is generated (S43).

  Next, the control device 201 specifies the focal length that maximizes the edge intensity from each quadratic approximate curve generated for each video included in the test video (S44). Next, the control device 201 specifies the shortest focal length as the fine adjustment start reference position FcsMax_rough_Min among the focal lengths at which the specified edge intensity is maximum (S45), and performs rough adjustment processing on the front screen E1 or the fixed screen D. Exit.

  In FIG. 31, the control device 201 reads the value of the fine adjustment start correction value Fcs_Fine_AddLower from the hard disk device as a parameter for fine adjustment processing, and adjusts the value obtained by subtracting the fine adjustment start correction value Fcs_Fine_AddLower from the fine adjustment start reference position FcsMax_rough_Min. The start position is calculated as FCS_Start (S50). Next, the control device 201 reads the value of the adjustment width FCS_Step_Len, the value of the number of adjustments FCS_Step_Num, and the like from the hard disk device (S51).

  The adjustment width FCS_Step_Len as a parameter for fine adjustment processing is shorter than the adjustment width FCS_Step_Len as a parameter for coarse adjustment processing, and the number of adjustments FCS_Step_Num as a parameter for fine adjustment processing is used as a parameter for coarse adjustment processing. The number of adjustments is determined to be greater than or equal to FCS_Step_Num.

  Further, depending on the accuracy of the coarse adjustment process, the adjustment count FCS_Step_Num as the parameter for the fine adjustment process may be set to be less than the adjustment count FCS_Step_Num as the parameter for the coarse adjustment process.

  In the hard disk device of the control device 201, a fine adjustment start correction value Fcs_Fine_AddLower value, an adjustment width FCS_Step_Len value, and an adjustment count FCS_Step_Num value are stored in advance as parameters for fine adjustment processing.

  Here, the control device 201 acquires edge strength for each image included in the test image while changing the focal length of the projector mechanism B2 based on the adjustment start position FCS_Start, the adjustment width FCS_Step_Len, and the number of adjustments FCS_Step_Num. To do.

  That is, the control device 201 controls the focal length of the projector mechanism B2 so that the focal length changes as FCS_Start + FCS_Step_Len × (adjustment count−1) based on the adjustment start position FCS_Start, the adjustment width FCS_Step_Len, and the adjustment count FCS_Step_Num (S52). Then, the edge strength for each video included in the test video is acquired (S53).

  When the edge strength corresponding to the adjustment count FCS_Step_Num is acquired for each video included in the test video, the control device 201 sets the focal length corresponding to the adjustment count as the Y axis, and the edge strength for each video included in the test video. A quadratic approximate curve with X as the X axis is generated (S54).

  Next, the control device 201 specifies the focal length that maximizes the edge strength from each quadratic approximate curve generated for each video included in the test video, and determines the focal length that maximizes the identified edge strength. The weighted average is determined as the focal length of the projector mechanism B2 with respect to the target screen, that is, the front screen E1 or the fixed screen D (S55). Next, the control device 201 stores the determined focal length in the EEPROM 231 of the projector mechanism B2 (S56), and ends the fine adjustment processing for the target screen.

  In FIG. 29, when the fine adjustment processing for the front screen E1 is completed, the control device 201 controls the actuator 204 so that the camera 202 moves to the fixed screen shooting position when the test video is displayed on the fixed screen D. (S35).

  The control device 301 adjusts the posture of the projector mechanism B2 relative to the projector cover B1 by controlling the projection posture adjustment device 304 according to the adjustment amount calculated based on the images taken by the cameras 302 and 303. As described above, the control device 301 and the projection posture adjustment device 304 constitute a projection posture adjustment unit.

  The projection posture adjusting device 304 includes drivers 305 a to 305 c that adjust the tightening degree of the nut 2213 with respect to the connecting screw portion 2210 shown in FIGS. 11 and 15, and the direction in which the nut 2213 is tightened and loosened by the control of the control device 301. Actuators 306a to 306c such as servo motors for driving the drivers 305a to 305c, respectively.

  The projection posture adjustment device 304 is configured to move up and down between a standby position and a drive position in which the nut 2213 can be tightened or loosened by the drivers 305a to 305c under the control of the control device 301. Yes.

  The control device 301 adjusts the attitude of the projector mechanism B2 with respect to the projector cover B1 by controlling the actuators 306a to 306c according to the adjustment amount calculated based on the images taken by the cameras 302 and 303.

  An adjustment jig 350 shown in FIG. 34 is installed in the upper part of the front surface of the fixed screen D. 34A is a front view of the adjustment jig 350, FIG. 34B is a side view of the adjustment jig 350, and FIG. 34C is a rear view of the adjustment jig 350. Show. The adjustment jig 350 is shaped so that the front surface of the fixed screen D is substantially extended and the upper end portion of the designed fixed screen D has a horizontal plane.

  The adjustment jig 350 includes a main body 351 having a width approximately equal to the width of the front surface of the fixed screen D, regulation pins 352 and 353 attached to both ends of the main body 351, and an adjustment tool disposed on the upper front surface of the fixed screen D. And a display member 354 having a display surface that is flush with the front surface of the fixed screen D when the jig 350 is installed.

  In the adjustment jig 350, each of the regulation pins 352 and 353 is positioned at the upper end of the front of the fixed screen D when the adjustment jig 350 is installed on the upper front of the fixed screen D. And a flange member 411 that sandwiches the front upper portion of the fixed screen D with the main body 351.

  Thus, the main body 351 and the regulation pins 352 and 353 constitute an installation unit that is installed at the upper front end of the fixed screen D. Specifically, the main body 351 and the regulation pins 352 and 353 constitute a fitting means that fits on the upper front end of the fixed screen D.

  In the present embodiment, the adjustment jig 350 has been described as being installed on the fixed screen D by fitting the fixed screen D between the main body 351 and the flange members 411 of the regulation pins 352 and 353. The adjustment jig 350 may be installed on the fixed screen D in another manner.

  For example, the adjustment jig 350 may be installed on the fixed screen D by forming a groove in which the flange member 411 of the restriction pins 352 and 353 is fitted at the upper end of the fixed screen D.

  Further, instead of the main body 351 and the regulation pins 352 and 353, a convex portion is formed in the width direction of the lower end of the display member 354, and a concave portion in which the convex portion is fitted in the width direction of the upper end of the fixed screen D is formed. Thus, the adjustment jig 350 may be installed on the fixed screen D.

  The display member 354 has such a size that the boundary of the image projected by the projector mechanism B2 is displayed when the adjustment jig 350 is installed on the upper part of the front surface of the fixed screen D (see FIG. 39 and the like).

  In FIG. 33, the third adjustment device 300 moves the stage 310 that moves in the front-rear and left-right directions and the left-right rotation direction according to the control of the control device 301, and the projector cover B <b> 1 according to the control of the control device 301. And a clamp mechanism 311 for fixing to the head.

  On the stage 310, the screen unit C to which the projection unit B is attached is fitted so as to be interlocked with the stage 310. Therefore, the control device 301 can move the screen unit C in the front-rear and left-right directions and the left-right rotation direction by controlling the stage 310.

(Adjustment in the Rz axis direction)
The control device 301 adjusts the Rz axis direction of the projector mechanism B2 with respect to the projector cover B1 by controlling the actuators 306b and 306c.

  Specifically, as illustrated in FIG. 35, the control device 301 adjusts the inclination SB_θ of the front lower end L1 connecting the lower front L1A and the lower front L1B of the fixed screen D in the image captured by the camera 302, and adjustment. An error Error_Rz_deg (= AX_θ−SB_θ) between the inclination AX_θ of the front upper end L2 connecting the front upper L2A and the front upper L2B of the image projected on the display member 354 of the jig 350 is calculated.

  Since the fixed screen D is set to be horizontal, the inclination SB_θ of the front lower end L1 is physically guaranteed to be horizontal (180 °). Further, since the image projected by the projector mechanism B2 is taken by the camera 302, if the attitude of the projector mechanism B2 is horizontal, the inclination AX_θ of the front upper end L2 is horizontal (180 °). Therefore, the occurrence of an error between SB_θ and AX_θ indicates that the attitude of the projector mechanism B2 is not horizontal.

  When the error Error_Rz_deg is within an allowable range (for example, error angle ± 0.5 °), the control device 301 determines that the Rz axis direction of the projector mechanism B2 has been adjusted. Specifically, the control device 301 has an error Error_Rz_deg larger than Spec_Rz_Lower (for example, −0.5 °) which is a lower limit (minus error) of the tilt error, and an upper limit Spec_Rz_Upper (for example, an upper limit (plus error) of the tilt error). , + 0.5 °), it is determined that the Rz axis direction of the projector mechanism B2 is adjusted. Note that the value of Spec_Rz_Lower and the value of Spec_Rz_Upper are stored in advance in the hard disk device of the control device 201.

  When the error Error_Rz_deg is outside the allowable range, the control device 301 executes the Rz axis adjustment process. In the Rz axis adjustment process, the control device 301 controls the actuators 306b and 306c to drive the drivers 305b and 305c so that the error Error_Rz_deg is within the allowable range.

  In the hard disk device of the control device 301, the connecting portion R2 and the connecting portion R3 of the connecting hole 2200A through which the connecting screw portion 2210 screwed to the nut 2213 of the connecting portions R2 and R3 whose tightening amounts are adjusted by the drivers 305b and 305c pass. The distance N_X between the center and the number of pulses PM_Pulse_Ratio necessary to rotate each driver 305a to 305c (100 to 10,000 Pulses depending on the resolution of the actuators 306a to 306c), and the connection The value of the pitch (distance between the threads) Pitch (for example, 0.7 mm) of the screw portion 2210 and the nut 2213 is stored in advance.

  The control device 301 uses the calculated inclination error Error_Rz_deg, the distance N_X read from the hard disk device, the number of pulses PM_Pulse_Ratio for one rotation, the pitch Pitch, and the number of pulses PM2_Pulse and PM3_Pulse of the drive signal output to the actuators 306b and 306c as follows: It calculates based on Formula (13)-(14), respectively. The control device 301 outputs a drive signal having a PM2_Puls pulse to the actuator 306b, and outputs a drive signal having a PM3_Puls pulse to the actuator 306c.

(Adjustment in Ry axis direction)
The control device 301 adjusts the Ry axis direction of the projector mechanism B2 with respect to the screen unit C by controlling the stage 310.

  Specifically, as illustrated in FIG. 36, the control device 301 includes an angle formed by the vertical line L3 and the horizontal line L4 included in the adjustment video, that is, included in the adjustment video in the image captured by the camera 302. The difference between the inclination θy of the vertical line L3 and the inclination θx of the horizontal line L4 is calculated.

  The control device 301 reduces the error Error_Ry_deg (= (θy−θx) −90) by subtracting 90 degrees from the difference (= θy−θx) between the inclination θy of the vertical line L3 and the inclination θx of the horizontal line L4 included in the adjustment video. ) Is calculated.

  Specifically, the projector mechanism B2 projects an adjustment image with an angle formed by the vertical line L3 and the horizontal line L4 of 90 °, but the projector mechanism B2 is displaced in the Ry axis direction with respect to the fixed screen D. When it is, the horizontal line L4 is inclined in the lower right (upper left) direction or the lower left (upper right) direction.

  For this reason, when the projector mechanism B2 is displaced in the Ry-axis direction with respect to the fixed screen D, the angle formed by the vertical line L3 and the horizontal line L4 of the adjustment video imaged by the camera 302 is not 90 °. Error_Ry_deg is not 0.

  When the error Error_Ry_deg is within an allowable range (for example, ± 0.3 °), the control device 301 determines that the Ry axis direction of the projector mechanism B2 has been adjusted. Specifically, the control device 301 determines that the error Error_Ry_deg is larger than Spec_Ry_Lower (for example, −0.3 °) that is a lower limit (minus error) of the tilt error, and Spec_Ry_Upper (for example, the upper limit (plus error) of the tilt error). If the angle is smaller than + 0.3 °, it is determined that the Ry axis direction of the projector mechanism B2 is adjusted. The hard disk device of the control device 201 stores a value of Spec_Ry_Lower and a value of Spec_Ry_Upper in advance.

  When the error Error_Ry_deg is outside the allowable range, the control device 301 executes the Ry axis adjustment process. In the Ry axis adjustment process, the control device 301 controls the stage 310 so that the error Error_Ry_deg is within an allowable range.

  In the hard disk device of the control device 301, the value of the coefficient Ry_adj_Ratio according to the error Error_Ry_deg (or Table 1) for calculating the required rotation angle Val_Stage_θ required for the stage 310 in order to make the error Error_Ry_deg within the allowable range A map of the coefficient Ry_adj_Ratio as shown) is stored in advance.

  The control device 301 calculates the required rotation angle Val_Stage_θ (= Error_Ry_deg × Ry_adj_Ratio) required for the stage 310 by multiplying the error Error_Ry_deg by the coefficient Ry_adj_Ratio. The control device 301 outputs to the stage 310 a drive signal for rotating the stage 310 by the rotation amount Val_Stage_θ.

(Adjustment in the X-axis direction)
The control device 301 adjusts the X-axis direction of the projector mechanism B2 with respect to the screen unit C by controlling the stage 310.

  Specifically, as shown in FIG. 37, the control device 301, in the image taken by the camera 302, coordinates of the midpoint of the front lower end L1 connecting the front lower L1A and the front lower L1B of the fixed screen D ( The difference Val_x_Pixel (= A_X−) of the X coordinate from the coordinates (A_X, A_Y) of the intersection of the vertical line L3 and the horizontal line L4 included in the image projected on the display member 354 of the adjustment jig 350 and SB_X, SB_Y). SB_X) is calculated.

  If the difference Val_x_Pixel of the X coordinate calculated in this way is a positive value (A_X is a value larger than SB_X), it indicates that the position of the projector mechanism B2 is shifted to the lower front L1B side. If the difference Val_x_Pixel is a negative value (A_X is smaller than SB_X), it indicates that the position of the projector mechanism B2 is shifted to the lower front L1A side.

  Unlike general image data, data representing an image shot through the camera 302 is subjected to sub-pixel processing by image processing in the control device 301, so that the actual distance of one pixel is 0. Converted to 037 mm.

  The control device 301 calculates a distance error Error_x_dist (= Val_x_Pixel × PixelRatio) corresponding to the difference Val_x_Pixel (Pixel) with the conversion coefficient PixelRatio (mm / Pixel) representing the length per pixel.

  When the error Error_x_dist (mm) is within an allowable range (for example, ± 0.3 mm), the control device 301 determines that the X-axis direction of the projector mechanism B2 has been adjusted. Specifically, the control device 301 determines that the error Error_x_dist is larger than the lower limit Spec_X_Lower (for example, −0.3 mm) of the position error in the X axis direction, and the upper limit Spec_X_Upper (for example, +0.3 mm) of the position error in the X axis direction. If smaller, it is determined that the X-axis direction of the projector mechanism B2 has been adjusted. Note that the value of PixelRatio, the value of Spec_X_Lower, and the value of Spec_X_Upper are stored in advance in the hard disk device of the control device 301.

  Specifically, the value of PixelRatio is 0.037 if 0.037 mm per pixel. The length per pixel can be calculated from the resolution of the image projected from the projector mechanism B2 and the projection distance from the projector mechanism B2 to the fixed screen D.

  When the error Error_x_dist is outside the allowable range, the control device 301 executes the X axis adjustment process. In the X-axis adjustment process, the control device 301 controls the stage 310 so that the error Error_x_dist is within the allowable range. The control device 301 outputs to the stage 310 a drive signal for moving the stage 310 in the X axis (left and right) direction by an error Error_x_dist.

(Adjustment in the Rx axis direction)
The control device 301 adjusts the Rx axis direction of the projector mechanism B2 relative to the projector cover B1 by controlling the actuators 306a to 306c.

  Specifically, as illustrated in FIG. 38, the control device 301 determines the inclination SB_θ of the front lower end L1 (see FIG. 35) of the fixed screen D in the image captured by the camera 302 and the image captured by the camera 303. A difference Val_Rx_deg (= θx2−SB_θ) with respect to the inclination θx2 of the horizontal line L4 included in the adjustment image projected on the side surface (right surface reflection portion D2) of the fixed screen D is calculated.

  The hard disk device of the control device 301 stores an optimum value Target_Rx value (for example, 34.4 °) obtained by actual measurement using the adjustment reference screen unit C. The control device 301 calculates an error Error_Rx_deg (= Val_Rx_deg−Target_Rx) from the difference between the difference Val_Rx_deg and the optimum value Target_Rx.

  When the error Error_Rx_deg is within an allowable range (for example, 34.2 ° to 34.6 °), the control device 301 determines that the Rx axis direction of the projector mechanism B2 is adjusted. Specifically, the control device 301 determines that the Rx axis direction of the projector mechanism B2 is adjusted when the error Error_Rx_deg is larger than the lower limit Spec_Rx_Lower of the tilt angle error and smaller than the upper limit Spec_Rx_Upper of the tilt angle error. To do. Note that a value of Spec_Rx_Lower (for example, 34.2 °) and a value of Spec_Rx_Upper (for example, 34.6 °) are stored in the hard disk device of the control device 301 in advance.

  When the error Error_Rx_deg is outside the allowable range, the control device 301 executes the Rx axis adjustment process. In the Rx axis adjustment process, the control device 301 controls the actuators 306a to 306c according to the angle of the error and drives the drivers 305a to 305c so that the error Error_Rx_deg is within the allowable range.

  In the hard disk device of the control device 301, the value of the coefficient Rx_adj_Ratio corresponding to the error Error_Rx_deg (or shown in Table 2) in order to calculate the adjustment angle Adj_Rx_Deg of the Rx axis in the projection posture adjustment device 304 that makes the error Error_Rx_deg within an allowable range. Such a map of conversion coefficients Rx_adj_Ratio) is stored in advance. For example, in Table 2, when the value of the difference Val_Rx_deg is 33.98, −0.90 is selected as the coefficient Rx_adj_Ratio.

  The control device 301 calculates the adjustment angle Adj_Rx_Deg (= Error_Rx_deg × Rx_adj_Ratio) of the Rx axis by multiplying the error Error_Rx_deg by the conversion coefficient Rx_adj_Ratio.

  The hard disk device of the control device 301 includes a connecting screw portion 2210 screwed to a nut 2213 of the connecting portion R2 whose tightening amount is adjusted by the driver 305b and a nut 2213 of the connecting portion R3 whose tightening amount is adjusted by the driver 305c. The distance N_Y between the line segment connecting the centers of the connecting holes 2200A through which the screw passes and the centers of the connecting holes 2200A through which the connecting screw portion 2210 screwed to the nut 2213 of the connecting portion R1 whose tightening amount is adjusted by the driver 305a (see FIG. 12) is stored in advance.

The control device 301 outputs a drive signal having a PM1_Pulse pulse to the actuator 306a, outputs a drive signal having a PM2_Pulse pulse to the actuator 306b, and outputs a drive signal having a PM3_Pulse pulse to the actuator 306c.

(Adjustment in the Y-axis direction)
The control device 301 adjusts the Y-axis direction of the projector mechanism B2 with respect to the projector cover B1 by controlling the actuators 306a to 306c.

  Specifically, as shown in FIG. 39, the control device 301, in an image taken by the camera 302, coordinates (the midpoint of the front lower end L1 connecting the lower front 1A and the lower front L1B of the fixed screen D ( A distance Val_y_Pixel from SB_X, SB_Y) to the coordinates (C_X, C_Y) which is the upper end of the image projected on the display member 354 of the adjustment jig 350 of the perpendicular bisector L5 with respect to the lower front end of the fixed screen D is calculated. To do.

  The control device 301 calculates the distance Val_y_Pixel (= C_Y−SB_Y) by subtracting the Y coordinate SB_Y of the midpoint of the front lower end of the fixed screen D from the distance A_Y in the image taken by the camera 302.

  The hard disk device of the control device 301 stores an optimum value Target_Y value (Pixel) obtained by actual measurement using the adjustment reference screen unit C. The control device 301 calculates an error Error_y_Pixel (= Val_y_Pixel−Target_Y) from the difference between the distance Val_y_Pixel and the optimum value Target_Y. The control device 301 calculates a distance error Error_y_dist (= Val_y_Pixel × PixelRatio) corresponding to the difference Val_y_Pixel with the conversion coefficient PixelRatio (mm / Pixel).

  Specifically, when the value of the optimal value Target_Y is 1200 Pixel and the value of the distance Val_y_Pixel is 1250 Pixel, the error of the value of the distance Val_y_Pixel with respect to the value of the optimal value Target_Y is 50 Pixel, and the value of the conversion coefficient PixelRatio is 0. If 037, the error Error_y_dist value is 1.85 mm.

  When the error Error_y_dist is within an allowable range (for example, ± 1.0 mm), the control device 301 determines that the Y-axis direction of the projector mechanism B2 has been adjusted. Specifically, the control device 301 determines that the error Error_y_dist is larger than the lower limit Spec_Y_Lower (for example, −1 mm) of the position error in the Y-axis direction and smaller than the upper limit Spec_Y_Upper (for example, +1 mm) of the position error in the Y-axis direction.

Note that the value of Spec_Y_Lower and the value of Spec_Y_Upper are stored in advance in the hard disk device of the control device 301.

  When the error Error_y_dist is outside the allowable range, the control device 301 executes the Y-axis adjustment process. In the Y-axis adjustment process, the control device 301 controls the actuators 306a to 306c and drives the drivers 305a to 305c so that the distance Error_y_dist is within the allowable range.

  The control device 301 calculates the number of pulses PM1_Pulse to PM3_Pulse of the drive signal output to the actuators 306a to 306c based on the following equation (18). Since PM2_Puls and PM3_Puls have the same value as PM1_Puls, the control device 301 substitutes the value of PM1_Puls into PM2_Puls and PM3_Puls, respectively.

  The control device 301 outputs a drive signal having a PM1_Pulse pulse to the actuator 306a, outputs a drive signal having a PM2_Pulse pulse to the actuator 306b, and outputs a drive signal having a PM3_Pulse pulse to the actuator 306c.

(Z-axis adjustment)
The control device 301 adjusts the Z-axis direction of the projector mechanism B2 with respect to the screen unit C by controlling the stage 310.

  Specifically, as illustrated in FIG. 40, the control device 301 displays the Y coordinate SB_Y of the midpoint of the front lower end of the fixed screen D and the display member 354 of the adjustment jig 350 in the image captured by the camera 302. The difference Val_z_Pixel (= A_Y−SB_Y) between the Y coordinate A_Y of the intersection of the vertical line L3 and the horizontal line L4 included in the projected image is calculated.

  The hard disk device of the control device 301 stores an optimum value Target_Z value (for example, 1280 Pixel) obtained by actual measurement using the adjustment reference screen unit C. The control device 301 calculates an error Error_z_Pixel (= Val_z_Pixel × PixelRatio) from the difference between the difference Val_z_Pixel and the optimum value Target_Z.

  When the error Error_z_dist (mm) is within an allowable range (for example, ± 0.2 mm), the control device 301 determines that the Z-axis direction of the projector mechanism B2 has been adjusted. Specifically, the control device 301 determines that the error Error_z_dist is larger than the lower limit Spec_Z_Lower (for example, −0.2 mm) of the position error in the Z-axis direction, and the upper limit Spec_Z_Upper (for example, +0.2 mm) of the position error in the Z-axis direction. If smaller, it is determined that the Z-axis direction of the projector mechanism B2 has been adjusted. Note that the value of Spec_Z_Lower and the value of Spec_Z_Upper are stored in advance in the hard disk device of the control device 301.

  When the error Error_z_dist is outside the allowable range, the control device 301 executes the Z-axis adjustment process. In the Z-axis adjustment process, the control device 301 controls the stage 310 so that the error Error_z_dist is within the allowable range.
