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

  In the pachislot machine of this 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]

That is, the projector mechanism B2 is provided with a plurality of square holes 2201c provided in the left end portion 2201a and the right end portion 2201b of the upper pedestal B220. 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).

The inclination in the left-right direction (roll angle) and the inclination in the front-rear direction (pitch angle) can be adjusted.

  By using the upper pedestal B220 and the lower pedestal B221 as described above, the projector mechanism B2 is attached to the projector cover B1 so that the positioning and the optical axis can be adjusted.

  As described above, the upper pedestal B220, the lower pedestal B221, and the connecting portions R1, R2, and R3 form a projection device holding mechanism that holds the projector mechanism B2 so that the posture with respect to the projector cover B1 can be adjusted. The upper pedestal B220 constitutes a first member fixed to the projector cover B1, and the lower pedestal B221 constitutes a second member fixing the projector mechanism B2.

The relay plate mounting portion B301 is formed so as to protrude inward from the inner side surfaces of the left and right side wall portions B13 and B13. The relay plate mounting portion B301 has a relay plate mounting surface B301a formed substantially horizontally.

  A mounting hole B301b and a position adjusting hole B301c are formed as through holes in the relay plate mounting surface B301a. The mounting hole B301b is a screw hole for mounting the relay plate B300 to the relay plate mounting portion B301 by screw fastening. The position adjusting hole B301c is formed at a position facing the square hole 2201c (see FIG. 11) of the upper base B220 when the relay plate B300 is attached to the relay plate attachment portion B301.

It is attached.

  Each of the distance sensors 106 a to 106 c detects the distance to the detection point with reference to the position sensor device 102, but the adjustment driver device 101 and the position sensor device 102 are fixed, and each of the position sensor devices 102 is Since the main bodies of the distance sensors 106a to 106c are fixed, the distance that is the detection result of each of the distance sensors 106a to 106c can be handled as the position of the detection point.

  The mirror adjustment device 100 further includes a clamp mechanism 107 that fixes the projector cover B1 and a drive mechanism 108 that drives the clamp mechanism 107 under the control of the control device 103.

  A positioning member 109 for positioning the position and height of the front side of the projector cover B1 by being fitted inside the front surface of the projector cover B1 is attached to the upper portion of the position sensor device 102. The mirror adjusting device 100 fixes the projector cover B1 by suppressing both sides of the protrusion 131 (see FIG. 16) formed on the side wall B13 of the projector cover B1 by the positioning member 109 and the clamp mechanism 107.

  As shown in FIG. 22, the adjustment driver device 101 and the position sensor device 102 are arranged so as to face each other with the mirror unit B3 temporarily fixed to the projector cover B1 fixed to the mirror adjustment device 100 interposed therebetween.

  In the present embodiment, the drivers 104a to 104c of the adjustment driver device 101 and the distance sensors 106a to 106c of the position sensor device 102 are respectively matched in the width direction and the height direction of the adjustment driver device 101 and the position sensor device 102.

  In FIG. 21, the control device 103 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, an input port, an output port, an input device, and a display. And a general-purpose computer device including the device.

  The hard disk device of the computer device stores a program (so-called application software) for causing the computer unit to function as the control device 103, an operating system (so-called OS) for managing the program, and various parameters. In other words, the computer device functions as the control device 103 when the CPU executes a program stored in the hard disk device.

  The control device 103 controls the adjustment driver device 101 based on the detection result of the position sensor device 102. Specifically, the control device 103 controls the actuators 105a to 105c of the adjustment driver device 101 so that the positions detected by the distance sensors 106a to 106c become predetermined positions.

  Here, the predetermined position is a target value for adjusting the position and orientation of the mirror unit B3 with respect to the projector cover B1, and is stored in the hard disk device of the control device 103.

  A mirror adjustment operation by the mirror adjustment apparatus 100 according to the first embodiment of the present invention configured as described above will be described with reference to FIG. The mirror adjustment operation described below is started 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 mirror adjustment device 100. Is done.

  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 pulse number 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 mirror adjustment device 100 according to the first 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.

  Further, the mirror adjustment device 100 according to the first embodiment of the present invention causes the position sensor device 102 to detect a plurality of positions of the reflection surface of the mirror unit B3, and causes the adjustment driver device 101 to detect the rear 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 mirror adjustment device 100 according to the first 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 focus 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, instead of the sub control device SS, the control device 201 of the focus adjustment device 200 shown in FIG. 26 is connected to the projector mechanism B2 via the relay substrate CK.

  As shown in FIG. 26, the focus 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. It has a camera 202 that constitutes a photographing means for photographing the projected screen unit C, 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 mirror 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 focus adjustment apparatus 200 includes the shooting position changing mechanism 203 that changes the shooting position of the camera 202, there is no need 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 hardly change in the state exposed to the projector mechanism B2, the control device 201 controls the projector mechanism with respect to the fixed screen D. A focal length A of B2 and a 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 near the bottom surface at the center 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 factor is determined in advance by verification so that the higher the display area of each video included in the test video is, the more easily a place where the player is gazing.

  In this 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, and Wtd7 = 1.0 are determined in advance, 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 as the focal length on the screen for the EEPROM 231 as a storage medium.

  The focal length setting operation by the focus adjustment apparatus 200 according to the first 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).

  Next, the control device 201 controls the front screen drive mechanism E2 so that the fixed screen D is exposed to the projector mechanism B2 (S36), and causes the projector mechanism B2 to project a test image for the fixed screen D. (S37).

  Next, the control device 201 executes the coarse adjustment process shown in FIG. 30 for the fixed screen D (S38), and executes the fine adjustment process shown in FIG. 31 for the fixed screen D (S39).

  Note that the coarse adjustment process for the fixed screen D is the same as the coarse adjustment process for the front screen E1, and thus the description thereof is omitted. Further, the fine adjustment process for the fixed screen D is the same as the fine adjustment process for the front screen E1, and thus the description thereof is omitted.

  Here, the various parameters FCS_Start, FCS_Step_Len, and FCS_Step_Num in the coarse adjustment processing for the fixed screen D may be the same as, or part of, the same as the various parameters FCS_Start, FCS_Step_Len, and FCS_Step_Num in the rough adjustment processing for the front screen E1. May be different.

  In addition, the various parameters Fcs_Fine_AddLower, FCS_Step_Len, and FCS_Step_Num in the fine adjustment processing for the fixed screen D may be all the same as the various parameters Fcs_Fine_AddLower, FCS_Step_Len, and FCS_Step_Num in the fine adjustment processing for the front screen E1, all may be the same. May be different. When the fine adjustment process for the fixed screen D is completed, the control device 201 ends the focal length setting operation.

  As described above, the focus adjustment apparatus 200 according to the first embodiment of the present invention maximizes the edge strength of the image obtained by photographing the test video image projected on the screen unit C by the projector mechanism B2. Since the focal length of the projector mechanism B2 is set, even if the material, shape, or installation position of the screen unit C is changed, the focal length of the projector mechanism B2 can be optimally set, so that the manufacturing cost can be suppressed. .

Even if the screen unit C has a three-dimensional screen such as the fixed screen D for output to B2, the optimum focus in consideration of the sharpness of the image displayed on all display surfaces in the three-dimensional shape The distance can be set in the projector mechanism B2.

  Further, in the focus adjustment apparatus 200 according to the first embodiment of the present invention, the shooting position changing mechanism 203 that changes the shooting position of the camera 202 changes the shooting position based on switching of each screen of a plurality of screens. Since a camera 202 that does not have a function of adjusting the focal length can be used, manufacturing costs can be reduced.

<Projector attitude adjustment process P3>
In the projector attitude adjustment process P3, the attitude of the projector mechanism B2 with respect to the projector cover B1 is adjusted by the projector attitude adjustment device 300.

  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 on the upper portion of the 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 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 projector attitude adjusting device 300 moves the stage 310 that moves in the front / rear / right / left direction 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 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 equations (15) to (17). 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. Is determined that the Y-axis direction of the projector mechanism B2 has been adjusted. 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.

  In the hard disk device of the control device 301, the value of the coefficient Z_adj_Ratio according to the difference Val_z_dist for calculating the required movement amount Val_z_dist required for the stage 310 in order to make the error Error_z_dist within the allowable range (or shown in Table 3). Such a map of the coefficient Z_adj_Ratio) is stored in advance. In the coordinates handled in the image processing, for example, A_Y is approximately 2560 and SB_Y is approximately 3840, so that the calculated Val_z_Pixel is a negative value.

  The control device 301 calculates a required movement amount Val_Stage_Y_dist (= Error_z_dist × Z_adj_Ratio) required for the stage 310 by multiplying the error Error_z_dist by a coefficient Z_adj_Ratio. The control device 301 outputs a drive signal representing the required movement amount Val_Stage_Y_dist to the stage 310.

In the figure, a fixing plate B321 used when the upper base B220 is fixed to the relay plate B300 is also shown.

  The upper pedestal B220 is provided with three connecting holes 2200A for connecting the lower pedestal B221. Similar to the first embodiment, the three connecting holes 2200A are arranged so as not to be positioned on the same straight line in a plane (horizontal plane) along the upper base B220.

  The lower pedestal B221 has a rectangular main body B221a, a right side B221b and a left side B221c that extend forward with a step with the main body B221a, and a rear with a step with the main body B221a. This is a sheet metal member provided with a rear end B221d.

  As shown in FIG. 46, the right side B221b is formed by bending the right side of the front end of the main body B221a downward and outward. The left side B221c is formed by bending the left side of the front end of the main body B221a downward and outward. As shown in FIG. 47, the rear end B221d is formed by bending the rear end of the main body B221a downward and bending a part of the portion bent downward outward. The right part B221b, the left part B221c, and the rear end part B221d are formed so as to be positioned on the same plane.

  A connecting screw portion 2210 is integrally formed on the right side B221b, the left side B221c, and the rear end B221d so as to protrude upward corresponding to the three connecting holes 2200A of the upper base B220. Similarly to the first embodiment, the three connecting screw portions 2210 are also arranged so as not to be positioned on the same straight line in a plane (horizontal plane) along the right side B221b, the left side B221c, and the rear end B221d. Yes.

  Similar to the first embodiment, the upper pedestal B220 and the lower pedestal B221 are connected to each other at three connecting portions corresponding to the three connecting holes 2200A and the three connecting screw portions 2210 so that the distance between them can be adjusted. Is done. The three connecting portions are each configured by a connecting hole 2200A, a connecting screw portion 2210, a coil spring 2211, a washer 2212, and a nut 2213 (see FIG. 15).

  As shown in FIG. 44, the lower pedestal B221 is provided with a plurality of screw holes 2214 for screwing the case B22. As the case B22, one having the same configuration as that of the first embodiment can be adopted. However, in this embodiment, as shown in FIG. 48, a case B22 having a rectangular parallelepiped box shape is adopted. Yes.

  Similarly to the first embodiment, the case B22 houses a lens unit B21 (see FIG. 10), an LED board, a DMD board, a heat sink, an intake fan, and the like, which are internal components of the projector mechanism B2. A projector control board B23 (see FIG. 10) is fixed to the lower surface of the case B22.

  A lens unit cover B222 (see FIG. 10) is attached to the front opening B22k provided on the front surface of the case B22. The lens unit B21 is accommodated in the case B22 in a state where the projection lens 210 (see FIG. 10) is covered with the lens unit cover B222.

  Although not shown in the figure, the case B22 includes two intake fans 244A at a position more to the left than the center in the left-right direction (near the right end of the left side B221c when attached to the lower pedestal B221 (see FIG. 49)). -244B is arrange | positioned so that it may rank with front and back. A heat sink is provided on the left side of the two intake fans 244A and 244B.

  In addition, an intake port B22A is provided on the right side surface of the case B22 (see FIG. 48), and an exhaust port B22E is provided on the left side surface of the case B22 (see FIG. 49). As a result, in the case B22, a flow of air exhausted from the exhaust port B22E while forcibly taking in air from the intake port B22A by the intake fans 244A and 244B and taking heat away from the heat sink is formed.

  As shown in FIG. 49, the case B22 is attached to the lower pedestal B221 by screw fastening, and its upper end surface (upper wall portion B22F shown in FIG. 48) is the inner surface of the main body B221a of the lower pedestal B221. Abut. Further, in a state where the upper pedestal B220 and the lower pedestal B221 are connected, the main body B221a of the lower pedestal B221 is located above the upper pedestal B220. Accordingly, the upper wall portion B22F of the case B22 is also positioned above the upper pedestal B220.

  In this regard, in the first embodiment, the upper end of the case B22 is attached to the lower pedestal B221, and the upper pedestal B220 is disposed higher than that. For this reason, the case B22 cannot be arranged in the space formed between the upper pedestal B220 and the lower pedestal B221 (the gap portion indicated by the arrow S in FIG. 14).

  On the other hand, in the present embodiment, an opening is formed in the upper base B220, and the upper end of the case B22 is arranged by arranging the case B22 so that the upper end (upper wall portion B22F) of the case B22 passes through the opening. The (upper wall portion B22F) can be positioned above the upper base B220. Thereby, the gap portion indicated by the arrow S in FIG. 14 can be used as a space for arranging the case B22.

  As described above, as compared with the first embodiment, the relative position of the case B22 (projector mechanism B2) with respect to the upper base B220 is moved upward, so that the front portion provided on the front surface of the case B22 is provided. A part of the upper base B220 is arranged in front of the opening B22k (see FIG. 48) (see FIG. 49). That is, a part of the upper pedestal B220 is placed in front of the projection lens 210 (see FIG. 10) installed so as to correspond to the front opening B22k. Thereby, it seems that the light emitted from the projection lens 210 is blocked by the upper pedestal B220.

  However, the irradiation light is not blocked in this way. That is, in the present embodiment, the irradiation light is emitted from a portion below the optical axis of the projection lens 210. In other words, when the irradiation light is emitted, only the lower half of the projection lens 210 (the portion below the horizontal plane passing through the central portion in the vertical direction of the projection lens 210) is used. The light emission position of the projection lens 210 is different from that of a conventionally known projector (for example, see Japanese Patent Application Laid-Open No. 2008-058875).

  Thus, in the present embodiment, when the irradiation light is emitted, the upper half of the projection lens 210 is not used, and the irradiation light is emitted from a portion below the optical axis of the projection lens 210, as shown in FIG. Thus, the upper pedestal B <b> 220 arranged in front of the projection lens 210 exists above the optical axis of the projection lens 210. Therefore, the path of the light emitted from the projection lens 210 is lower than the upper pedestal B220, and the irradiation light is not blocked by the upper pedestal B220.

  Further, the lower pedestal B221 is bent downward to form the right side B221b, the left side B221c, and the rear end B221d, so that the right side B221b, the left side B221c, and the rear end B221d are respectively above. The upper pedestal B220 and the lower pedestal B221 can be connected so that the upper pedestal B220 is arranged. Thereby, the structure similar to 1st Embodiment is employable about the structure of three connection parts, changing the structure of upper side base B220 and lower side base B221 from 1st Embodiment.

  In the present embodiment, the case B22 is described as having the upper wall portion B22F. However, as in the first embodiment, the case B22 (see FIG. 10) with the upper side opened may be used. Good. Further, the method of attaching the case B22 to the lower pedestal B221 is not particularly limited, and the case B22 is attached to the lower pedestal B221 by using the stay B223a (see FIG. 10) as in the first embodiment. It is good as well.

  As described above, in this embodiment, by disposing a part of the case B22 above the upper pedestal B220, it is possible to move the case B22 upward compared to the first embodiment. A new space can be created in the lower region of the case B22. Such an effect is obtained by changing the configuration of the upper pedestal B220 from the first embodiment, and the projector cover B1 can adopt the same configuration as that of the first embodiment.

  However, in the present embodiment, the projector cover B1 having a configuration different from that of the first embodiment is adopted in consideration of other effects. Hereinafter, the projector cover B1 according to the present embodiment will be described.

  A first through hole B300a is formed in the main body B300A. A second through hole B300b is formed in each of the front side part B300B and the rear side part B300C. Similar to the first embodiment, the first through hole B300a is a hole through which the cap bolt B320 (see FIG. 17) is inserted when the relay plate B300 is attached to the upper base B220. On the other hand, the second through hole B300b is a hole through which a screw is inserted when the relay plate B300 is attached to the relay plate attachment portion B301 by screw fastening.

  As shown in FIG. 50, an opening B400 having an open upper side is provided on both the left and right sides in front of the projector cover B1. The opening B400 has a shape that approximates a hexagonal shape formed by sides E to J (see FIG. 51) in a top view.

  As shown in FIG. 53, wall surfaces (wall surface B401e, wall surface B401f, wall surface B401g, wall surface B401h, wall surface B401i, and wall surface B401j) are formed continuously from each side downward with sides E to J as the upper end. ing. The wall surface B401j (see FIG. 50) formed continuously from the side J is shorter in the vertical direction than the other wall surfaces B401e to B401i.

  As shown in FIG. 55, an opening B400 that opens toward the upper side of the projector cover B1 and a cavity B402 formed below the position adjustment surface B301d of the relay plate mounting portion B301 communicate with each other inside the projector cover B1. ing.

[Adjustment of pachislot machine]
Next, adjustment at the time of manufacturing the pachislot machine 1 according to the second embodiment of the present invention will be described with reference to FIGS. 56 to 69. As shown in FIG. 56, the adjustment at the time of manufacturing the pachislot machine 1 according to the second embodiment of the present invention includes a mirror adjustment step P11, a first mirror fixing step P12, a focus adjustment step P13, and a projector attitude adjustment. There are a process P14, a projector position adjustment process P15, and a second mirror fixing process P16.

  In FIG. 56, in order to facilitate understanding of the invention, an example in which each of the processes P11 to P16 is executed one by one is shown. For example, a series of processes including the mirror adjustment process P11 and the first mirror fixing process P12 are performed. The process and the series of processes including the focus adjustment process P13 and the projector attitude adjustment process P14 can be performed in parallel.

  Moreover, in the following description, although the example using the manufacturing apparatus according to each process P11-P16 is demonstrated, you may use one manufacturing apparatus with respect to a some process. Moreover, you may comprise one manufacturing apparatus by a some manufacturing apparatus by conveying a manufacturing target object using an automatic conveyance mechanism.

<Mirror adjustment process P11>
The mirror adjustment step P11 is the same as the mirror adjustment step P1 in the first embodiment of the present invention. That is, the mirror adjustment step P11 in the present embodiment is executed according to the mirror adjustment operation shown in FIG. 23 using the mirror adjustment device 100 shown in FIG.

<First mirror fixing step P12>
In FIG. 9, the angle adjustment hole B111a is formed in the mirror unit B3 in order to adjust the vertical direction of the image displayed on each screen of the screen unit C. The angle adjustment holes B111b and B111c are formed in the mirror unit B3 in order to adjust the horizontal direction of the image displayed on each screen of the screen unit C.

  In FIG. 56, in the first mirror fixing step P12, the screws B112 passed through the angle adjustment holes B111b and B111c are fixed to the projector cover B1, but the screws B112 passed through the angle adjustment holes B111a are fixed to the projector cover B1. do not do. The screw B112 passed through the angle adjustment hole B111a is fixed to the projector cover B1 in a second mirror fixing step P16 described later.

  In the first mirror fixing step P12, the mirror unit B3 whose position and orientation (reflection angle) with respect to the projector cover B1 are adjusted in the mirror adjusting step P11 by the first mirror fixing device 500 whose schematic configuration is viewed from the front in FIG. Is fixed to the projector cover B1. That is, the first mirror fixing device 500 constitutes a reflecting device fixing means for fixing the horizontal position and posture of the mirror unit B3 with respect to the projector cover B1.

  The first mirror fixing device 500 fixes the frame 501, ejection mechanisms 502 b and 502 c that eject a fixing agent that is solidified by light of a specific wavelength, irradiation devices 503 b and 503 c that irradiate light of a specific wavelength, and the projector cover B 1. A clamp mechanism 504 for moving, a moving mechanism 505 for moving the projector cover B1 fixed to the clamp mechanism 504, and a control device 506 for controlling each part of the first mirror fixing device 500.

  In the present embodiment, an ultraviolet curable adhesive (hereinafter simply referred to as “UV adhesive”) is used as the fixing agent. Therefore, the light of the specific wavelength in this embodiment means ultraviolet rays.

  The clamp mechanism 504 is fixed to a pedestal 507 movably provided by the moving mechanism 505, and fixes the projector cover B1 to the pedestal 507 by suppressing both sides of the side wall portion B13 of the projector cover B1 with the rear surface facing forward.

  The moving mechanism 505 moves the pedestal 507 between a standby position, a first position where the UV adhesive is discharged by the discharge mechanisms 502b and 502c, and a second position where the irradiation devices 503b and 503c irradiate ultraviolet rays. Can do.

  Discharge mechanisms 502b and 502c are attached to the frame 501. When the projector cover B1 moved by the moving mechanism 505 is in the first position, the discharge mechanisms 502b and 502 are attached to positions corresponding to the angle adjustment holes B111b and B111c of the projector cover B1.

  Each discharge mechanism 502b, 502c is controlled by the control device 506 so that the head side portion of each screw B112 passed through the angle adjustment holes B111b, B111c and the peripheral portion of each angle adjustment hole B111b, B111c are bonded. , UV adhesive is discharged.

  Specifically, the discharge mechanism 502b is formed with two discharge holes 502ba and 502bb at an interval of approximately the same distance as the diameter of the head of the screw B112, and the discharge mechanism 502c has approximately the same diameter as the head of the screw B112. Two discharge holes 502ca and 502cb are formed at a distance interval.

  The discharge mechanism 502b is configured such that the center position of the discharge holes 502ba and 502bb and the position of the center of the head of the screw B112 substantially coincide with each other and the head side portion of the screw B112 and the angle adjustment hole B111b through the discharge holes 502ba and 502bb. A UV adhesive is discharged to the periphery.

  The discharge mechanism 502c is configured so that the center position of the discharge holes 502ca and 502cb and the center position of the head of the screw B112 substantially coincide with each other and the head side portion of the screw B112 and the angle adjustment hole B111b through the discharge holes 502ca and 502cb. A UV adhesive is discharged to the periphery.

  As described above, the first mirror fixing device 500 discharges the UV adhesive at two locations with respect to one screw B112, so that the fixing strength of the screw B112 with respect to the projector cover B1 is increased.

  Irradiation devices 503 b and 503 c are attached to the frame 501. Each irradiation device 503b, 503c is attached to each ejection mechanism 502b, 502c at a position separated in the left-right direction in the drawing by a predetermined distance longer than at least the diameter of the angle adjustment hole B111.

  In other words, each of the irradiation devices 503b and 503c has each angle adjustment hole B111b, when the projector cover B1 moved by the moving mechanism 505 is at a second position separated from the first position by a predetermined distance in the horizontal direction in the drawing. It is attached at a position corresponding to B111c.

  Each irradiation device 503b, 503c is provided with an LED that irradiates ultraviolet rays from the center of the hole toward the entire surface of the hole. Each irradiation device 503b, 503c causes the LED to emit light in accordance with control by the control device 506. The UV adhesive discharged by the discharge devices 502b and 502c is cured by the ultraviolet rays irradiated (5 seconds to 60 seconds) by the irradiation devices 503b and 503c. In addition, the irradiation time according to the component and characteristic of a UV adhesive agent is set for the irradiation time of an ultraviolet-ray.

  The moving mechanism 505 is fixed directly or indirectly to the frame 501. The moving mechanism 505 moves the pedestal 507 between the standby position, the first position, and the second position under the control of the control device 506.

That is, in the computer device, the computer device functions as the control device 506 when the CPU executes a program stored in the hard disk device.

  As described above, the first mirror fixing device 500 fixes the screw B112 provided in the mirror unit B3 in order to adjust the horizontal direction of the image displayed on the screen unit C (commonly called screw lock). In the subsequent manufacturing process, the screw B112 is prevented from being displaced.

  For this reason, in the subsequent manufacturing process, it is difficult for the first mirror fixing device 500 to adjust the relative position and orientation of the projector mechanism B2 and the screen unit C under the influence of the displacement of the screw B112. And an increase in adjustment process due to readjustment of the mirror unit B3 can be prevented.

  In the present embodiment, the moving mechanism 505 is controlled by the control device 506 to have a standby position, a first position for discharging the UV adhesive, and a second position for curing the UV adhesive. The example in which the base 507 to which the clamp mechanism 504 is fixed is moved with respect to the frame 501 has been described.

  On the other hand, the moving mechanism 505 controls the frame 501 between the standby position, the first position for discharging the UV adhesive, and the second position for curing the UV adhesive under the control of the control device 506. The pedestal 507 to which is fixed may be moved with respect to the clamp mechanism 504.

  Further, the first mirror fixing device 500 and the mirror adjusting device 100 shown in FIG. 21 may be integrally configured. In the case of such a configuration, the ejection mechanisms 502b and 502c and the irradiation devices 503b and 503c are provided side by side with respect to the drivers 104b and 104c in the mirror adjustment device 100, and the moving mechanism 505 responds to each process. The projector cover B1 fixed to the clamp mechanism 504 at the position may be moved in the left-right direction in the drawing.

  When the reference marker BM1 and the adjustment markers T1 and T2 overlap, the adjustment markers T1 and T2 are reflected by the reference marker BM1, so that one or both of the reference marker BM1 and the adjustment markers T1 and T2 can be identified by the camera 603. You will not be able to shoot.

  Therefore, the adjustment markers T1 and T2 are separated from each other with the optical axis of the projector mechanism B2 interposed therebetween in order to prevent the upper sides of the adjustment markers T1 and T2 from being coincident with the optical axis of the projector mechanism B2 and overlapping the reference marker BM1.

  As shown in FIG. 60B, the control device 604 intersects the upper side of the adjustment marker T1 and the side away from the optical axis in the captured image captured by the camera 603 when the fixing mechanism 601 is in the first position. The coordinates (X1, Y1) of the midpoint C1p between the coordinates of T1p and the coordinates of the intersection T2p between the upper side of the adjustment marker T2 and the side away from the optical axis are calculated.

  When the fixing mechanism 601 is in the second position, the control device 604 includes the coordinates of the intersection T1p between the upper side of the adjustment marker T1 and the side away from the optical axis in the captured image taken by the camera 603, and the adjustment marker. The coordinates (X2, Y2) of the midpoint C2p between the coordinates of the intersection T2p between the upper side of T2 and the side side away from the optical axis are calculated.

  The control device 604 specifies the coordinates (Xm, Ym) of the reference marker BM1 in the captured image captured by the camera 603 when the fixing mechanism 601 is at the first position or the second position. It should be noted that the test screen 602 and the camera 603 are either directly or so that the coordinates (Xm, Ym) of the reference marker BM1 are the same regardless of whether the fixing mechanism 601 is in the first position or the second position.

The control device 604 has the conversion coefficient PixelRatio, the optical axis deviation angle Val_Rx_deg in the Rx axis direction, the optical axis deviation angle Val_Ry_deg in the Ry axis direction, the optical axis deviation amount Val_X in the X axis direction, and the optical axis in the Y axis direction. Deviation amount Val_Y is calculated based on the following equations (19) to (22).

Val_X = (X2-Xm) × PixelRatio (21)
Val_Y = (Y2-Xm) × PixelRatio (22)

  The control device 604 includes an optical axis deviation angle Val_Rx_deg in the Rx axis direction, an optical axis deviation angle Val_Ry_deg in the Ry axis direction, an optical axis deviation amount Val_X in the X axis direction, and an optical axis deviation amount Val_Y in the Y axis direction. If everything is within the allowable range, the optical axis adjustment is skipped.

  For example, the allowable range of Val_Rx_deg is −0.1 ° <Val_Rx_deg <0.1 °, the allowable range of Val_Ry_deg is −0.1 ° <Val_Ry_deg <0.1 °, and the allowable range of Val_X is −0. 0.1 mm <Val_X <0.1 mm, and the allowable range of Val_Y is −0.1 mm <Val_Y <0.1 mm. These allowable ranges are stored in advance in the hard disk device of the control device 604.

If is not within the allowable range, the optical axis is adjusted as follows.

  The control device 604 calculates the adjustment amount Val_Stage_θ in the left-right rotation direction of the projector movement mechanism 606 and the adjustment amount Val_Stage_X in the left-right direction of the projector movement mechanism 606 based on the following equations (23) and (24).

Val_Stage_θ = Val_Ry_deg (23)

  The hard disk device of the control device 604 includes a connecting screw portion 2210 screwed to the nut 2213 of the connecting portion R2 whose tightening amount is adjusted by the driver 620b and the nut 2213 of the connecting portion R3 whose tightening amount is adjusted by the driver 620c. The distance N_Y between the line segment connecting the centers of the connecting holes 2200A through which the screw passes and the center 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 620a (see FIG. 12 (for example, 150 mm) is stored in advance.

(Distance between screw threads) Pitch value (for example, 0.7 mm) is stored in advance.

  The control device 604 obtains the number PM1_Rx_Pulse to PM3_Rx_Pulse of the drive signal output to the actuators 621a to 621c and the number of pulses PM1_Y_Pulse to PM3_Y_Pulse for the Y axis adjustment of the drive signal output to the actuators 621a to 621c below. Are calculated based on the equations (25) to (30).

  The control device 604 calculates the number of pulses PM1_Pulse to PM3_Pulse of the drive signal output to the actuators 621a to 621c based on the following equations (31) to (33).

PM1_Pulse = PM1_Rx_Pulse + PM1_Y_Pulse (31)
PM2_Pulse = PM2_Rx_Pulse + PM2_Y_Pulse (32)
PM3_Pulse = PM3_Rx_Pulse + PM3_Y_Pulse (33)

The control device 604 projects the second test image onto the test screen 602 from the projector mechanism B2. As shown in FIG. 61A, the second test image includes rectangular adjustment markers T3 and T4 in addition to the adjustment markers T1 and T2.

  When the reference marker BM2 and the adjustment markers T3 and T4 overlap, the adjustment markers T3 and T4 are reflected by the reference marker BM2, so that one or both of the reference marker BM2 and the adjustment markers T3 and T4 can be identified by the camera 603. You will not be able to shoot.

  For this reason, the adjustment markers T3 and T4 are separated from each other with the target position interposed therebetween in order to prevent the lower sides from overlapping the reference marker BM2 with the position of the reference marker BM2 as the target position.

  As shown in FIG. 61B, the control device 604 has an intersection T3p between the lower side of the adjustment marker T3 and the left side away from the target position in the captured image captured by the camera 603 when the fixing mechanism 601 is in the second position. And the coordinates (X3, Y3) of the midpoint C3p between the coordinates of the intersection T4p of the lower side of the adjustment marker T4 and the side away from the target position are calculated.

  When the fixing mechanism 601 is in the second position, the control device 604 includes the coordinates of the intersection T1p between the upper side of the adjustment marker T1 and the side away from the optical axis in the captured image taken by the camera 603, and the adjustment marker. The coordinates (X2, Y2) of the midpoint C2p between the coordinates of the intersection T2p between the upper side of T2 and the side away from the optical axis are calculated again (see FIG. 60B).

  The hard disk device of the control device 604 stores a target angle Target_Rz (for example, 90 °) in the Rz axis direction. The control device 604 calculates the deviation angle Val_Rz_deg of the optical axis in the Rz axis direction based on the following equation (34) with the target angle Target_Rz.

  If the deviation angle Val_Rz_deg of the optical axis in the Rz-axis direction is within the allowable range, the control device 604 skips adjustment of the optical axis in the Rz-axis direction. For example, the allowable range of Val_Rz_deg is set to −0.01 ° <Val_Rz_deg <0.01 °. This allowable range is stored in advance in the hard disk device of the control device 604. If the deviation angle Val_Rz_deg of the optical axis in the Rz-axis direction is not within the allowable range, the control device 604 adjusts the optical axis in the Rz-axis direction as follows.

  The hard disk device of the control device 604 includes a connecting screw portion 2210 screwed to the nut 2213 of the connecting portion R2 whose tightening amount is adjusted by the driver 620b and the nut 2213 of the connecting portion R3 whose tightening amount is adjusted by the driver 620c. The value of the length N_X (see FIG. 12) of the line segment that connects the centers of the connection holes 2200A through which is passed is stored in advance.

  The control device 604 calculates the Rz axis adjustment pulses PM2_Pulse and PM3_Pulse of the drive signals output to the actuators 621b and 621c based on the following equations (35) to (36), respectively.

  As described above, the control device 604 outputs the drive signals having the number of pulses PM2_Pulse and PM3_Pulse to the actuators 621b and 621c, respectively, and drives the actuators 621b and 621c, whereby the Rz axis direction of the optical axis of the projector mechanism B2 is changed. Adjusted.

(Z-axis adjustment)
The control device 604 calculates the coordinates (X2, Y2) and the coordinates (X3, Y3) again in the same way as when adjusting the Rz axis of the optical axis of the projector mechanism B2, and again sets the optical axis deviation angle Val_Rz_deg in the Rz axis direction. calculate.

  The hard disk device of the control device 604 stores a target amount Target_Z (for example, 273.4 mm) in the Z-axis direction of the optical axis. The control device 604 calculates the deviation amount Val_Z of the optical axis in the Z-axis direction based on the following equation (37) with the target amount Target_Z.

  If the deviation amount Val_Z of the optical axis in the Z-axis direction is within the allowable range, the control device 604 skips adjustment of the optical axis in the Z-axis direction. For example, the allowable range of Val_Z is set to −0.1 mm <Val_Z <0.1 mm. This allowable range is stored in advance in the hard disk device of the control device 604. If the deviation amount Val_Z of the optical axis in the Z-axis direction is not within the allowable range, the control device 604 adjusts the optical axis in the Z-axis direction as follows.

  In the hard disk device of the control device 604, the value of the coefficient Z_Adj_Ratio with respect to Val_Z (or a mathematical expression for calculating the coefficient Z_adj_Ratio or a map of the coefficient Z_adj_Ratio as shown in Table 4) is determined in advance and stored. Note that Val_Z in Table 4 is shown with Target_Z added.

  The control device 604 calculates the front-rear direction adjustment amount Val_Stage_Y of the projector moving mechanism 606 based on the following equation (38) with the coefficient Z_Adj_Ratio.

  Val_Stage_Y = Val_Z × Z_Adj_Ratio (38)

  As described above, the control device 604 outputs a signal representing the adjustment amount Val_Stage_Y in the front-rear direction of the projector moving mechanism 606 to the projector moving mechanism 606, and drives the projector moving mechanism 606, thereby driving the optical axis of the projector mechanism B2. The Z-axis direction is adjusted.

  As described above, in the projector mechanism B2, assembling of the case B22 attached to the lower pedestal B221 with respect to the upper pedestal B220 is adjusted. In the present embodiment, the control device 604 recalculates the deviation in each axial direction of the case B22 attached to the lower pedestal B221 with respect to the upper pedestal B220, and any of the deviations in each axial direction is within the allowable range. Otherwise, the above-described optical axis adjustment, Rz axis adjustment, and Z axis adjustment are executed again.

  Here, the control device 604 performs the optical axis adjustment, the Rz axis adjustment, and the Z axis adjustment for the allowable range for the deviation in each axial direction when determining whether the deviation in each axial direction is within the allowable range. Take it wider than the allowable range.

  For example, the control device 604 sets the allowable range of Val_Rx_deg to −0.2 ° <Val_Rx_deg <0.2 °, sets the allowable range of Val_Ry_deg to −0.2 ° <Val_Ry_deg <0.2 °, and sets the allowable range of Val_X to −0.5 mm <Val_X <0.5 mm, the allowable range of Val_Y is −0.5 mm <Val_Y <0.5 mm, the allowable range of Val_Rz_deg is −0.1 ° <Val_Rz_deg <0.1 °, and Val_Z The allowable range is set to -0.5 mm <Val_Z <0.5 mm, and it is determined whether or not the adjustment in each axis direction is executed again. These allowable ranges are stored in advance in the hard disk device of the control device 604.

  As shown in FIG. 67, the control device 701 projects the second adjustment image of the second aspect from the projector mechanism B2 onto the reel screen F1 at the exposure position. The second adjustment image of the second aspect is a single-color image in which the lowering contour matches the effect image, and the color of the second adjustment image of the second aspect is the same as the color of the first adjustment image Thus, it is composed of one color component of red, green, and blue color components, and the second adjustment image of the second aspect employs an image of only the green component.

  The control device 701 includes a Y coordinate (Pixel) R_A_LY of the second bottom side and a Y coordinate (Pixel) of the right bottom side of the second adjustment image of the second mode displayed on the reel screen F1 in the captured image taken by the camera 702. R_A_RY is detected.

  The hard disk device of the control device 701 stores a height offset value R¬_Offset (0 in this embodiment) for the reel screen F1. The control device 701 calculates the amount of displacement (Pixel) Val_Pos in the height direction based on the following equation (45) with the offset value R¬_Offset.

Val_Pos = (R_A_LY + R_A_RY) / 2− (R_B_LY + R_B_RY) / 2−R¬_Offset (45)

  Further, the control device 701 has a second image displayed in the analysis area 750 surrounded by the broken line in FIG. 67 in the present embodiment, outside the display area of the reel screen F1, in the captured image captured by the camera 702. The width (Pixel) R_A_Blob of the second adjustment image is calculated by blob analysis (the photographed image is binarized by a predetermined threshold value and converted into a black and white image and the blob (small chunk) is counted). The area R_A_Blob is defined as a displacement area (Pixel) Val_Blob.

  The control device 701 skips the coarse mirror adjustment if the deviation amount Val_Pos in the height direction and the deviation area Val_Blob are within the allowable ranges. For example, the allowable range of Val_Pos is −20 Pixel <Val_Pos <3 Pixel, and the allowable range of Val_Blob is Val_Blob ≦ 10000 Pixel. These allowable ranges are stored in advance in the hard disk device of the control device 701. The control device 701 performs coarse mirror adjustment as follows if any of the deviation amount Val_Pos and the deviation area Val_Blob in the height direction is not within the allowable range.

  The hard disk device of the control device 701 has a map as shown in Table 6 showing the rotation angle Val_angle of the screw B112 with respect to the deviation area Val_Blob when the deviation area Val_Blob exceeds a predetermined value (5000 pixels in the present embodiment). A map as shown in Table 7 showing the rotation angle Val_angle of the screw B112 with respect to the deviation area Val_Blob when the deviation area Val_Blob is less than a predetermined value and exceeding 0, and the deviation amount Val_Pos when the deviation area Val_Blob is 0 A map as shown in Table 8 representing the rotation angle Val_angle of the screw B112 is determined in advance and stored. In Tables 6 to 8, the displacement area Val_Blob is expressed in units of 20 pixels. The rotation angle is stored as 1 pixel as data.

  The control device 701 selects a map (Tables 6 to 8) based on the deviation area Val_Blob, specifies the rotation angle Val_angle of the screw B112 based on the selected map, and outputs the number of pulses of the drive signal output to the actuator 711. PM_Pulse is calculated based on the following equation (46).

PM_Pulse = Val_angle / 360 × PM_Pulse_Ratio (46)

  PM_Pulse_Ratio represents the number of pulses required to rotate the driver 710 once (for example, 15000 Pulse / 1 rotation), and is stored in the hard disk device of the control device 701 in advance.

  In this way, the control device 701 adjusts the angle of the mirror unit B3 in the vertical direction with respect to the projector cover B1 by outputting a drive signal having the number of pulses PM_Pulse to the actuator 711.

(Adjustment in Ry axis direction)
As shown in FIG. 67, the control device 701 projects the second adjustment image of the second aspect from the projector mechanism B2 onto the reel screen F1 at the exposure position, and from the captured image captured by the camera 702, the projector mechanism An adjustment amount in the Ry-axis direction of the screen unit C with respect to B2 is calculated.

  The control device 701 includes a Y coordinate (Pixel) R_A_LY of the second bottom side and a Y coordinate (Pixel) of the right bottom side of the second adjustment image of the second mode displayed on the reel screen F1 in the captured image taken by the camera 702. R_A_RY is detected.

  The hard disk device of the control device 701 stores an offset value R¬_Ry_Offset (in this embodiment, −10 Pixel) in the Ry axis direction for the reel screen F1. The control device 701 calculates the deviation angle Val_Ry in the Ry axis direction based on the following equation (47) with the offset value R¬_Ry_Offset.

Val_Ry = (R_A_RY−R_B_RY) − (R_A_LY−R_B_LY) −R¬_Ry_Offset (47)

  If the deviation angle Val_Ry in the Ry axis direction is within the allowable range, the control device 701 skips adjustment of the screen unit C in the Ry axis direction with respect to the projector mechanism B2. For example, the allowable range of Val_Ry is set to −1 Pixel <Val_Ry <1 Pixel. This allowable range is stored in advance in the hard disk device of the control device 701. If the deviation angle Val_Ry in the Ry axis direction is not within the allowable range, the control device 701 adjusts the screen unit C with respect to the projector mechanism B2 in the Ry axis direction as follows.

  In the hard disk device of the control device 701, the value of the conversion coefficient Ry_adj_Ratio for Val_Ry (or a map of the conversion coefficient Ry_adj_Ratio as shown in Table 9) is determined in advance and stored.

  The control device 701 calculates the adjustment amount Val_Stage_θ of the screen moving mechanism 705 in the left-right rotation direction based on the following equation (48) with the conversion coefficient Ry_adj_Ratio.

Val_Stage_θ = Val_Ry x Ry_adj_Ratio (48)

  In this way, the control device 701 outputs a signal representing the adjustment amount Val_Stage_Y in the left-right rotation direction of the screen moving mechanism 705 to the screen moving mechanism 705, and drives the screen moving mechanism 705, whereby the screen unit for the projector mechanism B2. The Ry axis direction of C is adjusted.

(Adjustment in the X-axis direction)
As shown in FIG. 66A, the control device 701 projects the second adjustment image of the first mode from the projector mechanism B2 onto the front screen E1 at the exposure position, and from the captured image captured by the camera 702, the projector mechanism An adjustment amount in the X-axis direction of the screen unit C with respect to B2 is calculated.

  The hard disk device of the control device 701 includes a conversion coefficient PixelRatio (0.1 mm / Pixel in the present embodiment) representing a length per pixel and an offset value X_Offset in the X-axis direction (in the present embodiment, 0) is stored. The control device 701 calculates the deviation amount Val_X in the X-axis direction based on the following equation (49) with the conversion coefficient PixelRatio and the offset value X_Offset.

Val_X = {(F_A_X1 + F_A_X2) / 2− (F_B_X1 + F_B_X2) / 2} × PixelRatio−X_Offset (49)

  In the hard disk device of the control device 701, the value of the coefficient X_Adj_Ratio with respect to Val_X (or the map of the coefficient X_Adj_Ratio as shown in Table 10) is determined in advance and stored.

  The control device 701 calculates the adjustment amount Val_Stage_X in the left-right direction of the screen moving mechanism 705 based on the following equation (50) with the coefficient X_Adj_Ratio.

Val_Stage_X = Val_X × X_Adj_Ratio (50)

  As described above, the control device 701 outputs a signal indicating the adjustment amount Val_Stage_X in the left-right direction of the screen moving mechanism 705 to the screen moving mechanism 705, and drives the screen moving mechanism 705, whereby the screen unit C for the projector mechanism B2 is operated. The X-axis direction is adjusted.

(Mirror fine adjustment)
The control device 701 adjusts the position of the screw B112 (see FIG. 9) passed through the angle adjustment hole B111a of the mirror unit B3 with respect to the projector cover B1 through the actuator 711 under the same control as the coarse mirror adjustment.

  In the hard disk device of the control device 701, in addition to the offset value R¬_Offset (0 in the present embodiment) for the reel screen F1 used for coarse mirror adjustment, it is used for fine mirror adjustment, but for the reel screen F1. The offset value R¬_Offset (−15 in this embodiment) of the height is stored.

  Also, the allowable range of the height direction displacement amount Val_Pos is −20 Pixel <Val_Pos <3 Pixel, and the allowable range of Val_Blob is Val_Blob ≦ 0. These allowable ranges for fine mirror adjustment are stored in advance in the hard disk device of the control device 701 in addition to the allowable range for rough mirror adjustment.

  If the deviation amount Val_Pos in the height direction and the deviation area Val_Blob are within the allowable ranges, the control device 701 skips mirror fine adjustment. The control device 701 performs mirror fine adjustment unless any of the deviation amount Val_Pos in the height direction and the deviation area Val_Blob is within the allowable range.

  As described above, the position and orientation of the projector mechanism B2 with respect to the screen unit C and the vertical position and orientation of the mirror unit B3 with respect to the projector cover B1 are adjusted.

  In order to determine the adjustment result, the control device 701 again calculates the deviation amount Val_Z, the deviation area Val_Blob, the deviation amount Val_Ry in the Ry axis direction, and the deviation amount Val_X in the X axis direction, as will be described below. In addition, instead of the height direction displacement amount Val_Pos, the height direction left displacement amount Val_L_Pos and the height direction right displacement amount Val_R_Pos are newly calculated, and the right side of the second adjustment image of the first mode is calculated. A deviation amount Val_opt is newly calculated.

  The hard disk device of the control device 701 stores a height offset value R¬_Offset (-15 in this embodiment) for the reel screen F1 used at the time of determination. The control device 701 calculates the deviations Val_L_Pos and Val_R_Pos in the height direction based on the following equations (51) and (52) with the offset value R¬_Offset.

Val_L_Pos ＝ R_A_LY−R_B_LY−R¬_Offset (51)
Val_R_Pos ＝ R_A_RY−R_B_RY−R¬_Offset (52)

  The control device 701 projects the first adjustment image from the projector mechanism B2 onto the front screen E1 at the exposure position, and from the captured image captured by the camera 702, the X coordinate RX of the right side of the front screen E1 is expressed by the following formula ( 53).

RX = (F_B_X4−F_B_X2) / (F_B_Y4−F_B_Y2) × (F_A_Y5−F_B_Y2) + F_B_X2 (53)

  The control device 701 calculates the right side deviation Val_opt based on the following equation (54).

Val_opt = F_A_X5-RX (54)

  The control device 701 is one of Z-axis direction displacement amount Val_Z, displacement area Val_Blob, Ry-axis direction displacement amount Val_Ry, X-axis direction displacement amount Val_X, height-direction displacement amount Val_L_Pos, Val_R_Pos, and right-side displacement Val_opt. Is not within the allowable range, the above-described detection of the reference coordinate information of the front screen E1, detection of the reference coordinate information of the reel screen F1, adjustment in the Z-axis direction, coarse mirror adjustment, adjustment in the Ry-axis direction, and adjustment in the X-axis direction. Perform adjustment and mirror fine adjustment again.

  For example, the control device 701 sets the allowable range of Val_Z to −5 Pixel <Val_Z <5 Pixel, sets the allowable range of Val_Blob to Val_Blob ≦ 0 Pixel, sets the allowable range of Val_L_Pos to −20 Pixel <Val_L_Pos <20 Pixel, and sets the allowable range of Val_R_Pos to −20 <Val_R_Pos <20 Pixel, Val_Ry allowable range is −30 Pixel <Val_Ry <30 Pixel, Val_X allowable range is −0.5 Pixel <Val_X <0.5 Pixel, and Val_opt allowable range is Val_opt ≦ 0.5 Pixel. Is determined to be within the allowable range. These allowable ranges are stored in advance in the hard disk device of the control device 701.

  A projector position adjustment operation performed by the projector position adjustment apparatus 700 according to the second embodiment of the present invention configured as described above will be described with reference to FIG.

  First, the control device 701 controls the screen clamp mechanism 703 to fix the screen unit C (S120). Next, the control device 701 controls the projection clamp mechanism 704 to fix the projector mechanism B2 (S121).

  Next, the control device 701 controls the sub CPU 1071 via the external terminal, moves the front screen E1 to the standby position, and moves the reel screen F1 to the exposure position (S122). Next, the control device 701 detects reference coordinate information of the reel screen F1 (S123).

  Next, the control device 701 controls the sub CPU 1071 (see FIG. 19) via an external terminal (not shown) to move the front screen E1 to the exposure position (S124). Next, the control device 701 detects reference coordinate information on the front screen E1 (S125). Next, the control device 701 adjusts the screen unit C in the Z-axis direction with respect to the projector mechanism B2 (S126).

  Next, the control device 701 controls the sub CPU 1071 via the external terminal, moves the front screen E1 to the standby position, and moves the reel screen F1 to the exposure position (S127).

  Next, the control device 701 controls the actuator 711, moves the driver 710 to the driving position, and performs rough mirror adjustment to adjust the vertical orientation of the mirror unit B3 relative to the projector cover B1 to be relatively rough (S128). Then, the driver 710 is moved to the driving position.

  Next, the control device 701 controls the sub CPU 1071 via the external terminal, moves the reel screen F1 to the standby position, and moves the front screen E1 to the exposure position (S129).

  Next, the control device 701 adjusts the Ry axis direction of the screen unit C with respect to the projector mechanism B2 (S130). Next, the control device 701 adjusts the X-axis direction of the screen unit C with respect to the projector mechanism B2 (S131).

  Next, the control device 701 moves the driver 707 to the driving position, and controls the actuator 708 so that the mounting screw T is tightened by the driver 707 (S132). Next, the control device 701 controls the projection clamp mechanism 704 to release the projector mechanism B2 (S133).

  Next, the control device 701 controls the actuator 711, moves the driver 710 to the drive position, and performs fine mirror adjustment to adjust the vertical orientation of the mirror unit B3 with respect to the projector cover B1 with relatively high accuracy ( In step S134, the control device 701 controls the actuator 711 to move the driver 710 to the standby position (S135).

  Next, the control device 701 determines whether or not the adjustment is completed (S136). That is, the control device 701 includes the Z-axis direction displacement amount Val_Z, the displacement area Val_Blob, the Ry-axis direction displacement amount Val_Ry, the X-axis direction displacement amount Val_X, the height-direction displacement amounts Val_L_Pos, Val_R_Pos, and the right-side displacement Val_opt. It is determined whether or not all the deviations are within an allowable range.

  When it is determined that the adjustment is completed, that is, when it is determined that all the deviations are within the allowable range (YES), the control device 701 controls the screen clamp mechanism 703 to release the screen unit C ( S137), the projector position adjusting operation is terminated. On the other hand, when it is determined that the adjustment is not completed, that is, when it is determined that any deviation is not within the allowable range (NO), the control device 701 returns the projector position adjustment operation to step S121.

  In the projector position adjustment operation described above, the control device 701 may continuously execute a series of processes from step S125 to S131 twice or more in order to improve adjustment accuracy.

  As described above, the projector position adjusting device 700 acquires coordinate information related to the display area of the screen unit C in the captured image as reference coordinate information from the captured image of the screen unit C onto which the first adjustment image is projected. Since the adjustment amount of the projection area of the projector mechanism B2 is calculated based on the captured image of the screen unit C onto which the second adjustment image of one aspect is projected and the reference coordinate information, the accuracy of the projection area of the projector mechanism B2 is calculated. In addition, it is possible to achieve uniformity in accuracy required for adjustment and suppression of manufacturing cost required for adjustment time.

  In addition, the projector position adjustment device 700 detects the boundary between the display area and the non-display area from the captured image captured by the camera 702 by the screen unit C on which the first adjustment image is projected. Coordinate information regarding the C display area can be acquired.

  In addition, the projector position adjustment device 700 obtains a captured image of the front screen E1 on which the second adjustment image of the first aspect having the markers M1 to M5 corresponding to the display area of the front screen E1 is projected, and the reference coordinate information. Based on this, since the adjustment amount of the projection area of the projector mechanism B2 is calculated, the accuracy of the projection area of the projector mechanism B2 can be ensured.

  The projector position adjusting device 700 also uses the projector mechanism based on the captured image of the reel screen F1 on which the second adjustment image of the second aspect whose lower outline matches the effect image and the reference coordinate information. Since the adjustment amount of the projection area of B2 is calculated, the image projected by the projector mechanism B2 is displayed outside the display area of the reel screen F1, thereby preventing the appearance of the effect image from being impaired. .

<Second Mirror Fixing Step P16>
In the second mirror fixing step P16, the display unit that has been assembled is subjected to the mirror adjustment step P11, the first mirror fixing step P12, the focus adjustment step P13, the projector attitude adjustment step P14, and the projector position adjustment step P15.

  Specifically, two discharge holes are formed in the discharge mechanism 802a at an interval of approximately the same distance as the diameter of the head of the screw B112. The discharge mechanism 802a is configured such that the center position of the two discharge holes and the center position of the head of the screw B112 substantially coincide with each other, the head side portion of the screw B112 and the peripheral portion of the angle adjustment hole B111b through the two discharge holes. The UV adhesive is discharged on the surface.

  As described above, the second mirror fixing device 800 discharges the UV adhesive to the screw B112 at two locations, so that the fixing strength of the screw B112 with respect to the projector cover B1 is increased.

The UV adhesive discharged by the discharge device 802a is cured by the ultraviolet rays irradiated (5 to 60 seconds) by the irradiation device 803a. In addition, the irradiation time according to the component and characteristic of a UV adhesive agent is set for the irradiation time of an ultraviolet-ray.

  The moving mechanism 805 is fixed directly or indirectly to the frame 801. The moving mechanism 805 moves the pedestal 807 between the standby position, the first position, and the second position under the control of the control device 806.
