The display unit A is a so-called projection mapping device including an irradiation light device B that emits irradiation light including an image, and a screen device C that causes an image to appear by being irradiated with irradiation light from the irradiation light device B. .

  Here, the projection mapping apparatus projects an image on the surface of a three-dimensional object such as a building or a natural object, and its position (for example, with respect to projection planes E11a and E12a of a front screen mechanism E1 described later) It is generated based on the projection distance, the angle, etc.) and the shape. By projecting the image according to the presentation information, a high-level, powerful presentation is made possible.

(Display unit A: irradiation light device B)
As shown in FIG. 4, the irradiation light device B has a projector mechanism B2 for emitting irradiation light forward, and a screen that is disposed in front of the projector mechanism B2 and the irradiation light from the projector mechanism B2 is arranged diagonally below and back It has a mirror mechanism B3 that reflects in the device C direction, and a projector cover B1 that houses a projector mechanism B2 and a mirror mechanism B3.

(Display unit A: irradiation light device B: projector mechanism B2)
The projector mechanism B2 is disposed at the rear in the cabinet 21 (see FIGS. 1 and 2). The projector mechanism B2 has a flat base member B22 horizontally disposed as shown in FIG. 5, FIG. 8 and FIG. As shown in FIG. 8, a lens mechanism B <b> 21 and a projector 5 are provided on the lower surface of the base member B <b> 22. The base member B22 constitutes a projector attachment mechanism B2A together with an attachment plate B20 disposed to face the lower side.

The lens mechanism B21 is disposed so as to emit toward the

  As shown in FIGS. 8 and 9, the mounting plate B20 has a spacer shaft B271 having a screw formed on its circumferential surface erected, for example, at three locations on the upper surface, and a spring B272 is loosely fitted. A through hole B220 corresponding to the spacer axis B271 is formed in the base member B22. The through hole B220 has a diameter that can penetrate only the spacer axis B271 and can not penetrate the spring B272.

  With this structure, the spring B272 is loosely fitted to each spacer axis B271 of the mounting plate B20, and the upper end portion of each spacer axis B271 is penetrated through the corresponding through hole B220 of the base member B22 to thereby complete the upper end portion of each spacer axis B271. Can be projected onto the base member B22. By screwing the double nut B275 onto the screw of each spacer shaft B271 in this state, the base member B22 and the mounting plate B20 can be mounted in a state of being disposed opposite to each other via the spacer shaft B271 and the spring B272. .

  For example, as shown in FIGS. 8 and 9, the double nut B275 is composed of a lower nut B274 and an upper nut B273. Here, the lower nut B 274 is larger in diameter than the upper nut B 273. The lower nut B 274 is screwed with the screw of the spacer shaft B 271 and rotated, so that the distance between the base member B 22 and the mounting plate B 20 at that position can be varied in the state where the spring B 272 intervenes. For example, when the nut B 274 is rotated in the direction in which the screw engagement with the spacer shaft B 271 is tightened, the distance is reduced, and when the nut B 274 is rotated in the loosening direction, the distance is increased.

  At three positions (three points) of the base member B22 where the tip of each spacer shaft B271 protrudes, the base member B22 at each position is appropriately rotated by appropriately turning the nut B274 in the tightening direction or the loosening direction of screwing. And the mounting plate B20 can be changed. As described above, according to the rotation mechanism of the double nut B275 at three points on the base member B22 according to the present embodiment, for example, on the XYZ coordinates shown in FIG. The projector 5 attached can be moved in the Y-axis direction (vertical direction) and can be rotated in the Z-axis direction. As described above, the nut B 274 having the function of adjusting the position in the Y-axis direction and the rotational position (Yθ) in the Z-axis direction is hereinafter referred to as an adjusting nut.

  As described above, after Y θ adjustment of the projector 5 by the adjustment nut B 274 is completed, the adjustment nut B 274 can be rotated in the loosening direction by tightening the nut B 273 until it abuts on the upper surface of the adjustment nut B 274 It can be fixed in the absence state. Hereinafter, the nut B273 having such a functional structure is referred to as a fixing nut.

The mounting piece B221 has a plurality of position adjustment holes B222 arranged in the front-rear direction of the base member B22. On the other hand, as a mechanism for fixing the base member B22, fixing members B25 and B26 are provided on the main body side of the display unit A, for example, on the projector cover B1 side. As shown in FIG. 9B, the fixing members B25 and B26 are provided with screw holes B251 for receiving the screwing of the mounting screws B223 for attaching the base member B22. Attachment of the base member B22 to the fixing members B25 and B26 is performed by adjusting the position of the attachment piece B221 to the position adjustment holes B222 at four places in the two attachment pieces B221 of the base member B22 via the plate washer B27. It can be carried out by screwing into the screw hole B <b> 251 after passing through the hole B <b> 222.

  Here, the position adjustment hole B222 of the mounting piece B221 has a hole diameter that allows the base member B22 to freely move in a state where the mounting screw B223 is penetrated. Thus, for example, in the mounting state of the base member B22 shown in FIG. 9, by rotating the mounting screw B223 in the direction in which the screwing to the screw hole B251 is sufficiently loosened, the position adjustment hole B222 of the mounting piece B221 to the mounting screw B223 The base member B22 can be moved, for example, in the left-right direction in FIG. 9B by an allowance of the hole diameter.

The projector 5 attached via the plate B20 can be moved in the X-axis direction (left-right direction). Thus, the projector mechanism B2 of the present embodiment, together with the rotation mechanism of the double nut B275 at the three points on the base member B22 described above, enables the XYθ adjustment of the projector 5.

The function of the adjustment stage 71 supports the XYθ adjustment of the projector 5 attached to the base member B22 via the mounting plate B20.

(Display unit A: irradiation light device B: mirror mechanism B3)
As shown in FIGS. 5 and 7, a mirror mechanism B3 is disposed in front of the projector mechanism B2 (the emission direction of the irradiation light). As shown in FIG. 6, the mirror mechanism B3 has a mirror holder B31, a reflection mirror B32 accommodated in the mirror holder B31, and mirror stoppers B33 and B34 for fixing both ends of the reflection mirror B32 to the mirror holder 31. doing. As also shown in FIG. 5, the front surface of the mirror holder B <b> 31 is formed in a rectangular shape. At each corner portion of the mirror holder B31, an angle adjustment hole B311 is formed, and a recess B312 is formed on the front surface centering on the angle adjustment hole 311.

  On the other hand, as shown in FIG. 6, a mirror holding portion B313 is formed on the rear surface of the mirror holder B31. The mirror holding portion B313 is formed at a central portion, and is formed in a size not overlapping the angle adjustment hole B311 and the mounting hole B314. Mirror stoppers B33 and B34 are provided on the left and right sides of the mirror holding portion B313, respectively. The mirror stoppers B33 and B34 have angle adjustment holes B331 and B341, and mounting holes B334 and B344, respectively.

  The mirror stoppers B33 and B34 are mounted so as to partially overlap with the mirror holding portion B313. Thus, the mirror stoppers B33 and B34 abut on both end portions of the reflection mirror B32 fitted in the mirror holding portion B313 in the left and right direction, and screwing is performed by the mounting holes B314 and B334B344 to mirror the reflection mirror B32 It is made to hold | maintain to holder B31.

  As shown in FIGS. 4 and 7, the mirror mechanism B3 configured as described above is provided on the inner side surface of the reflector holding portion B11 in the projector cover B1. The reflector holding portion B11 is formed at the center on the front surface of the projector cover B1, and is disposed so as to be exposed on the front side when the upper door mechanism UD is opened. The reflector holding portion B11 has an angle adjustment hole B111. The angle adjustment hole B111 is disposed at a position corresponding to the angle adjustment hole B311 of the mirror mechanism B3.

  A screw (not shown) is inserted from the front side into the angle adjustment hole B111 of the reflector holding portion B11, and the screw penetrates the angle adjustment hole B311 of the mirror holder B31. The angle adjustment holes B331 and B341 of the mirror stoppers B33 and B34 are formed as screw holes in which screws can be screwed, and the screws penetrating the angle adjustment hole B311 of the mirror holder B31 are of the mirror stoppers B33 and B34. It is screwed into the angle adjustment holes B331 and B341.

  When the screw is rotated in the direction in which the screw engagement with the angle adjustment holes B331 and B341 is loosened, the distance between the reflector holding portion B11 and the mirror stoppers B33 and B34 is increased. On the other hand, when the screw is rotated in the direction in which the screw engagement with the angle adjustment holes B331 and B341 is tightened, the distance between the reflector holding portion B11 and the mirror stoppers B33 and B34 is reduced.

  As described above, the mirror holder B31 and the mirror stoppers B33 and B34 are screwed together via the mounting holes B314, B334 and B344, whereby the reflection mirror is interposed between the mirror holder B31 and the mirror stoppers B33 and B34. B32 is held. Thus, the mirror holder B31, the reflection mirror B32, and the mirror stoppers B33 and B34 are integrated as a mirror mechanism B3, and the distance between the reflector holding portion B11 and the mirror stoppers B33 and B34 is changed by the rotation of a screw. Thus, the distance between the reflector holding portion B11 and the reflection mirror B32 can be increased or decreased. Thus, the mirror holder B31, the mirror stoppers B33 and B34, the mirror mechanism B3, and the reflector holding portion B11 constitute a distance adjusting means.

  FIG. 13 is a conceptual view showing the structure of the adjustment stage 71. As shown in FIG. The figure (a) is a top view, and the figure (b) has shown the lower side view of the figure (a). In FIG. 13B, for convenience, a state in which the display unit A to be adjusted is placed on the adjustment stage 71 is shown.

  As shown in FIG. 13, the adjustment stage 71 includes a first drive source 711A, a placement plate 712A driven by the first drive source 711A, and a pair of side members 713A and 713A coupled to the placement plate 712A. A first adjustment stage 71A, a lower support 710B, a second drive source 711B mounted on the lower support 710B, and a second adjustment stage 71B having a placement plate 712B driven by the second drive source 711B. The first adjustment stage 71A and the second adjustment stage 71B are separated from each other and configured to be individually drivable.

  In the first adjustment stage 71A, arms 7150 and 7150 are provided on the pair of side members 713A and 713A, respectively, and the arms 7150 and 7150 respectively have a pair of gripping members 7151a, 7151b, 7151a at their tips. , 7151 b. Each pair of arm portions 7151 and 7151 is configured to be rotatable between a position shown by a solid line and a position shown by a dotted line in FIG. 13B by a drive source such as an electric motor (not shown). Further, in the arm portions 7151 and 7151, each pair of gripping members 7151a, 7151b, 7151a and 7151b spreads at a predetermined interval when the arm portions 7151 and 7151 are in the position indicated by the solid line, and the arm portions 7151 and 7151 It is operable to be closed so as to be equal to or less than a predetermined interval (for example, the interval between the upper and lower grip positions B 225 and B 225 of the base member B 22 in FIG. 9) rotating to the position shown by the dotted line.

  Thus, the arm portions 7150 and 7150 in the pair of side surface members 713A and 713A are normally held at the positions indicated by solid lines in FIG. On the other hand, at the time of adjustment processing of the optical mechanism of the projector mechanism B2 of the display unit A placed on the placement plate 712B, the arm units 7150 and 7150 are rotated to the position shown by the dotted line in FIG. The pair of gripping members 7151a, 7151b, 7151a, 7151b of the arm units 7150, 7150 are driven to grip predetermined four places of the base member B22 of the projector mechanism B2, for example, the gripping position B225 of FIG. Ru.

  The second adjustment stage 71B is stopped by driving the first drive source 711A while holding the four places of the base member B22 by the pair of holding members 7151a, 7151b, 7151a, 7151b of the arm units 7150, 7150. Only the first adjustment stage 71A (projector mechanism B2) can be moved as it is (without moving the display unit A placed on the second adjustment stage 71B).

  Here, the direction in which the first adjustment stage 71A can be moved is, for example, the X-axis direction on the XYZ coordinate axes shown in FIG. 13 (b). Further, in this state, by driving the second drive source 711B separately from the first drive source 711A, the second adjustment stage 71B can be separated from the first adjustment stage 71A and moved in the X axis direction. .

  As described above, in the adjustment stage 71, the first adjustment stage 71A and the second adjustment stage 71B are configured to be separated and movable. Thus, when the display unit A is placed on the placement plate 712B, either one or both of the display unit A and the projector mechanism B2 inside can be moved individually. This function is particularly useful in position adjustment (rough adjustment) of the projector mechanism B2 when, for example, the projector mechanism B2 mounted in the main body of the display unit A is largely deviated from the original position.

  The adjustment stage 71 drives the second drive source 711B in a state where the arm members 7150 and 7150 of the first adjustment stage 71A do not grip the base member B22, moves only the second adjustment stage 71B, and moves the mounting plate 712B. It goes without saying that the display unit A mounted with the projector mechanism B2 can be moved integrally.

  Thus, in the optical mechanism position adjustment device 7, the adjustment stage 71 moves the projector mechanism B2 mounted with the projector 5 of the display unit A independently from the other portions of the display unit A including the front screen mechanism E1. Has a mechanism that can

(Mirror adjustment unit 72)
As shown in FIG. 11, the mirror adjustment unit 72 is located inside the reflector holding portion B11 of the mirror mechanism B3 of the display unit A while the display unit A placed on the adjustment stage 71 is stopped at the adjustment work position. The tilt adjustment of the reflection mirror B32 located at For example, the mirror adjustment unit 72 is provided with four electric drivers 725 (see FIGS. 5 and 6) corresponding to the four angle adjustment holes B311 (see FIGS. 5 and 6) of the mirror holder B31 that constitutes the mirror mechanism B3 together with the reflection mirror B32. 11). As a drive source of these electric drivers 725, for example, a stepping motor is used.

  In the mirror adjustment unit 72, the inclination adjustment of the reflection mirror B32 is performed based on the measurement result of the reflected light from the reflection mirror B32 in the laser measurement instrument 6 mounted on the measurement unit 75 described later. Specifically, after the front end portions of the four electric drivers 725 are inserted into the respective angle adjustment holes B111 of the reflector holding portion B11, these four electric drivers 725 are driven based on the above measurement results, and the angle of the mirror holder B31 This can be performed by rotationally driving a screw inserted in the adjustment hole B311.

(Mounting position adjustment unit 73)
As shown in FIG. 11, the attachment position adjustment unit 73 has a movable structure so as not to interfere with, for example, the display unit A mounted on the adjustment stage 71. For example, the mounting position adjustment unit 73 is configured to be reciprocally movable in the direction (arrows a1 and b1 directions) equivalent to the adjustment stage 71 by the transport rail 731 above the display unit A. The mounting position adjustment unit 73 is not limited to the configuration in which the mounting position adjustment unit 73 is installed at the position illustrated in FIG. 11, and may be configured to be movable on the transport rail 741, for example.

  The mounting position adjustment unit 73 mounts the projector 5 inside the projector mechanism B2 when the projector cover B1 is removed and the display unit A mounted with the projector mechanism B2 is stopped at the adjustment work position by the adjustment stage 71. It adjusts the position.

  The attachment position adjustment unit 73 fixes the base member B22 to the fixing members B25 and B26 while the projector mechanism B2 of the display unit A is stopped at the adjustment operation position (see FIG. 9A). The four electric drivers 735 respectively corresponding to the screws B 223 are provided, and the four electric drivers 735 respectively have a conveyance drive mechanism for conveying the entire unit movably to the position where the corresponding mounting screws B 223 can be adjusted. As a result, the mounting position adjustment unit 73 causes the four electric drivers 735 to face the corresponding mounting screws B 223, and rotationally drives each mounting screw B 223 in the direction of tightening or loosening the screw engagement with the screw hole B251.

  Here, when it is rotated by a predetermined amount in the direction of loosening the screw connection, the mounting screw B 223 is loosened, and the fixing of the base member B 22 through the plate washer B 27 is released. In this state, the base member B22 can be appropriately moved, for example, in the X-axis direction of FIG. 9B within the range of the allowance of the hole diameter of the position adjustment hole B222 of the mounting piece B221 with respect to the mounting screw B223. Thereafter, the movement is stopped at a desired position, and the corresponding mounting screws B 223 are screwed into the screw holes B 251 by the four electric drivers 735, whereby the base member B 22 can be fixed at the positions. Thereby, the attachment position of projector mechanism B2 (projector 5 mounted there) can be adjusted to the said position. That is, the mounting screw B 223 constitutes a fixing portion, and the electric driver 735 and the mounting position adjusting unit 73 constitute fixing portion adjusting means.

(Inclination adjustment unit 74)
As shown in FIG. 11, the tilt adjustment unit 74 is movable, for example, so as not to interfere with the display unit A mounted on the adjustment stage 71, and further includes a conveyance rail 731 for conveying the attachment position adjustment unit 73. The upper conveyance rail 741 is configured to be reciprocally movable in a direction (direction of arrows a 2 and b 2 in FIG. 11) orthogonal to the movement direction of the adjustment stage 71. In the tilt adjustment unit 74, for example, as in the attachment position adjustment of the projector 5 by the attachment position adjustment unit 73, the projector cover B1 is removed, and the display unit A in which the projector mechanism B2 is attached to the opening is at the adjustment operation position. When stopped, the inclination adjustment of the projector 5 mounted inside the projector mechanism B2 is performed.

  The tilt adjustment unit 74 is a spacer shaft erected from the mounting plate B20 at three locations of the base member B22 during the configuration of the projector mechanism B2 of the display unit A stopped at the adjustment operation position (see FIG. 9A). There are three double adjustment wrenches 745 corresponding respectively to the double nuts B 275 screwed onto the B 271 screws. As a drive source of the double adjustment wrench 745, for example, a servomotor is applied. In addition, the tilt adjustment unit 74 includes a drive mechanism for adjusting the position of the entire unit so as to be movable to a position where the three double adjustment wrenches 745 face the corresponding double nuts B 275 respectively.

  FIG. 14 is a view showing the structure of a double adjustment wrench 745 provided in the inclination adjustment unit 74. As shown in FIG. FIG. 14 (a) is a longitudinal sectional view of an essential part of the double adjustment wrench 745, and FIG. 14 (b) is a bottom view of FIG. 14 (a).

  As shown in FIG. 14, the double adjustment wrench 745 is formed of a cylindrical body having an inner cylindrical portion 7455a and an outer cylindrical portion 7451a for housing the inner cylindrical portion 7455a. The inner cylindrical portion 7455a constitutes a first wrench 7455, and has a diameter corresponding to the fixing nut B273 of the double nut B275. A first wrench portion 7456 fitted to the fixing nut B273 is provided on the surface facing the fixing nut B273 during adjustment of the double nut B275 of the first wrench 7455. The outer cylindrical portion 7451a constitutes a second wrench 7451 and has a diameter corresponding to the adjustment nut B274 of the double nut B275. A second wrench portion 7452 fitted to the adjusting nut B274 is provided on the surface facing the adjusting nut B274 when adjusting the double nut B275 of the second wrench 7451. The first wrench 7455 and the second wrench 7451 are configured to be able to rotate and move up and down individually.

  More specifically, the first wrench portion 7456 of the first wrench 7455 is shaped to engage with the fixing nut B273 of the double nut B275, and the second wrench portion 7452 of the second wrench 7451 is double It has a shape engaged with the adjustment nut B 274 of the nut B 275. As described above, the double adjustment wrench 745 includes the first wrench 7455 and the first wrench 7455 in which the fixing nut B273 for the double nut B275 and the adjustment nut B274 are fitted to the inner cylindrical portion 7455a and the outer cylindrical portion 7451a that houses the inner cylindrical portion 7455a. It has a double wrench structure in which two wrenches 7451 are rotatably provided individually.

  In the inclination adjusting unit 74, three double adjusting wrenches 745 having the structure of FIG. 14 are arranged in the same arrangement pattern as the arrangement positions of the three double nuts B275 on the base member B22. Thus, the tilt adjusting unit 74 causes the three double adjusting wrenches 745 to face the corresponding double nuts B 275 respectively, and the servomotor separates the first wrench 7455 and the second wrench 7451 of the double adjusting wrench 745 respectively. To adjust the tilt of the projector 5 attached to the base member B22 via the mounting plate B20 by separately rotating the fixing nut B273 of the double nut B275 and the adjusting nut B274. it can. That is, the double adjustment wrench 745 constitutes a double nut adjustment means.

  Here, first, the second wrench 7451 is rotationally driven to rotate the adjustment nut B 274 to adjust the tilt of the projector 5, and then the first wrench 7455 is rotationally driven to adjust the fixing nut B 273 for adjustment. The projector 5 can be held in the inclined state by rotating it until it abuts on. When the adjustment nut B 274 is rotated by the second wrench 7451, the fixing nut B 273 is engaged with the first wrench portion 7456 of the first wrench 7455 so as to be held unrotatable. Thus, when the adjustment nut B 274 is rotated by the second wrench 7451, the tightening torque is not transmitted to the fixing nut B 273, and the fixing force by the fixing nut B 273 to be tightened thereafter can be strengthened. .

  In addition, inclination adjustment of the projector 5 by the inclination adjustment unit 74 (three-point adjustment by rotational drive of the double nut B 275 by the double adjustment wrench 745), and attachment position adjustment of the projector 5 by the attachment position adjustment unit 73 (by the electric driver 735) Either of the four points adjustment by rotational driving of the mounting screw B 223 may be performed first. Further, the three-point adjustment and the four-point adjustment may be repeatedly adjusted a plurality of times respectively, or may be repeatedly performed a plurality of times alternately.

(Position adjustment process of optical mechanism of display unit A)
FIG. 16 is a flowchart showing the position adjustment process of the optical mechanism of the display unit A in the optical mechanism position adjustment device 7. FIGS. 17, 19 and 21 show operation images according to a series of processing steps for position adjustment in FIG.

  As shown in FIG. 16, in order to adjust the position of the optical mechanism of the display unit A in the optical mechanism position adjusting device 7, first, the display unit A on which the projector 5 is not mounted is mounted on the adjusting stage 71 (step S11). The display unit A to be mounted here is manufactured to the stage of leaving the mounting of the projector 5 and, for example, it is necessary for mounting the projector mechanism B2 including the projector 5 in the subsequent process on the upper part thereof. An opening (a mounting hole for installing the projector 5 of the display unit A described above) is formed. As described above, the optical mechanism position adjusting device 7 adjusts the position of the optical mechanism when assembling the display unit A. Next, the operation unit 7017 performs an input operation of a movement start instruction. By this operation, the integrated adjustment control unit 7012 sends a movement start instruction to the adjustment stage control unit 701, and the adjustment stage control unit 701 drives the adjustment stage 71 to move the display unit A without the projector 5 to the adjustment work position. (Step S12).

  Next, the operation unit 7017 performs an input operation of a measurement instrument closing instruction. By this operation, the integrated adjustment control unit 7012 sends a measurement instrument closing instruction to the measurement control unit 705, and the measurement control unit 705 moves the measurement unit 75 onto the display unit A, and the measurement unit 75 having the laser measurement instrument 6. Is moved from the opening to a suitable position in the space where the projector 5 is originally mounted in the display unit A and stopped at that position. Thus, the measurement unit 75 is inserted into the display unit A (step S13).

  Next, the operation unit 7017 performs an input operation of a measurement start instruction. By this operation, the integrated adjustment control unit 7012 sends a measurement start instruction to the measurement control unit 705, and the measurement control unit 705 controls the measurement unit 75 to measure the reflected light by the reflection mirror B32 that constitutes the mirror mechanism B3. The operation is performed (step S14). Subsequently, the integrated adjustment control unit 7012 sends an adjustment instruction to the mirror adjustment control unit 702 based on the measurement result of the reflected light in step S14, and the mirror adjustment control unit 702 drives the electric driver 725 of the mirror adjustment unit 72 to reflect Position adjustment of the mirror B 32 is executed (step S15).

  After the end of the process of adjusting the position of the reflecting mirror B32 in step S15, the operator performs an input operation of a retraction instruction for retracting the measurement unit 75 in the operation unit 7017. By this operation, the integrated adjustment control unit 7012 sends an evacuation instruction to the measurement control unit 705, and the measurement control unit 705 controls the measurement unit 75 to retract the measurement unit 75 from the display unit A. Subsequently, the integrated adjustment control unit 7012 sends a return instruction to the adjustment stage control unit 701, and the adjustment stage control unit 701 drives the adjustment stage 71 to move the display unit A with the measurement unit 75 retracted to the standby position ( Step S16).

  In FIG. 17, the processing operation from steps S11 to S16 in FIG. 16, that is, the display unit A without the projector 5 mounted at the standby position is mounted on the adjustment stage 71 (see FIG. 17A). Is moved to the adjustment work position (see (B) in the figure), the measurement unit 75 is inserted into the display unit A, and the reflected light measurement process is performed by the laser measuring instrument 6 (see (C) in the same figure) After adjusting the position of the reflecting mirror B32 based on the measurement result of the reflected light (refer to the same figure (D)) and further retracting the measurement unit 75 to the outside of the display unit A, the adjustment stage 71 is driven. The flow of processing for returning the display unit A to the standby position (see FIG. 6E) is schematically shown.

  In the reflected light measurement process (step S14 in FIG. 16) shown in FIG. 17C, the laser measurement instrument 6 of the measurement unit 75 inserted into the display unit A is controlled by the measurement control unit 705 as shown in FIG. As shown, the laser light is emitted, the reflected light of the laser light by the reflection mirror B3 is received, and the light reception output is sent to the measurement control unit 705. The integrated adjustment control unit 7012 takes in the light reception output of the laser measuring instrument 6 from the measurement control unit 705, and obtains the displacement amount from the preset reference light reception output of the laser light received this time from the light reception output.

  In the mirror position adjustment process (step S15 in FIG. 16) shown in FIG. 17D, the integrated adjustment control unit 7012 receives the laser beam based on the displacement amount of the laser beam obtained from the light reception output of the laser measuring instrument 6. An adjustment command is output that instructs the output to be the reference light reception output, that is, the displacement amount of the laser light to be zero. The mirror adjustment control unit 702 rotationally drives the four electric drivers 725 of the mirror adjustment unit 72 based on the above adjustment command, from the angle adjustment hole B111 of the reflector holding portion B11 to the angle adjustment holes B331 and B341 of the mirror stoppers B33 and B34. Fine adjustment of the reflection angle of the reflection mirror B32 with respect to the traveling direction of the irradiation light from the laser measuring instrument 6 so as to obtain the above-mentioned reference light reception output by rotating the screw screwed to the (see FIGS. 5 to 7) Do.

  Referring back to FIG. 16 again, the process after step S16 will be described. In step S16, when the display unit A with the measurement unit 75 retracted to the outside returns to the standby position, next, the projector 5 is placed on the regular mounting position of the display unit A (step S17). Here, the projector 5 is attached to the lower surface of a mounting plate B20 (see FIG. 8), which is a component of the projector mechanism B2, and is mounted on the display unit A together with the projector mechanism B2. At the time of this work, drive the four electric drivers 735 of the mounting position adjustment unit 73 from the integrated adjustment control unit 7012 and tighten the four mounting screws B 223 on the base member B 22 of the projector mechanism B 2 with respect to the screw holes B 251 The projector mechanism B2 is attached to the fixing members B25 and B26 by rotating in the direction. Here, for example, the fastening of the mounting screw B 223 with respect to the screw hole B 251 is adjusted to provide a state of temporary fastening, for example.

  Next, the movement start instruction is input in the operation unit 7017, and by this operation, the integrated adjustment control unit 7012 drives the adjustment stage 71 through the adjustment stage control unit 701 to move the display unit A to the adjustment work position ( Step S18).

  Subsequently, at the adjustment work position, the operation unit 7017 performs an input operation of an image projection instruction. By this operation, the integrated adjustment control unit 7012 sends an image projection instruction to the image projection control unit 707. The image projection control unit 707 causes the projector 5 to emit an image for projection mapping, and reflects the image after the position adjustment is completed. Control is made to reflect the light by the mirror B32 and to project the light onto the projection surface E11a of the front screen mechanism E1 (step S19).

  Further, when the input operation of the image projection instruction is received, the integrated adjustment control unit 7012 sends an imaging instruction to the imaging control unit 706, the imaging control unit 706 controls the camera 76, and the front screen mechanism E1 of the display unit A. A projection image on the projection plane E11a is photographed, and the photographed image is captured through the imaging control unit 706 and displayed on the display unit 7016 (step S20).

  After that, while the operator looks at the captured image of the camera 76 displayed on the display unit 7016, an inclination adjustment instruction or an attachment position adjustment instruction for adjusting so that the projection image and the projection surface E11a overlap in an appropriate positional relationship. In the operation unit 7017, the input operation of When the input operation of the inclination adjustment instruction is performed in the operation unit 7017, the integrated adjustment control unit 7012 sends the inclination adjustment instruction to the inclination adjustment control unit 704, and the inclination adjustment control unit 704 performs three double adjustment of the inclination adjustment unit 74. The wrench 745 is driven to adjust the tilt of the projector 5 (step S21).

  On the other hand, when the input operation of the attachment position adjustment instruction is performed in the operation unit 7017, the integrated adjustment control unit 7012 sends the attachment position adjustment instruction to the attachment position adjustment control unit 703, and the attachment position adjustment control unit 703 The four electric drivers 735 of the adjustment unit 73 are driven to rotate the four attachment screws B 223 for fixing the base member B 22 of the projector mechanism B 2 in the direction in which the screw engagement with the screw hole B 251 is loosened (see FIG. 9).

  As a result, the base member B22 is maintained in a state where it can move by an allowance with respect to the mounting screw B223 of the hole diameter of the position adjustment hole B222 of the mounting piece B221. In this state, the integrated adjustment control unit 7012 sends a position movement instruction to the adjustment stage control unit 701, and the adjustment stage control unit 701 drives the first adjustment stage 71A of the adjustment stage 71, and the arm members 7150 and 7150 make the base member B22. After the projector mechanism B2 is moved in the X direction on the XYZ coordinates in FIG. 9, for example, after adjusting the mounting position of the projector 5 (step S22) .

  After completion of the position adjustment processing of the projector 5 in step S22, the operator looks at the captured image of the camera 76 displayed on the display unit 7016 and combines the above-described tilt adjustment of the projector 5 with the projected image on the projection surface E11a. After confirming that the projector 5 is projected to an appropriate position, that is, that the projector 5 has been subjected to the accurate XYθ adjustment, the user inputs a fixing instruction from the operation unit 7017.

  By this operation, the integrated adjustment control unit 7012 sends a fixing instruction to the attachment position adjustment control unit 703. The attachment position adjustment control unit 703 drives the four electric drivers 735 of the attachment position adjustment unit 73 based on the fixing instruction to fix four base screws B223 of the projector mechanism B2 with the screw holes B251. The projector mechanism B2 is fixed to the fixing members B25 and B26 by rotating the screw mechanism in the tightening direction (step S23).

  After completing the fixing process of the projector mechanism B2 (projector 5) in step S23, the integrated adjustment control unit 7012 sends a return instruction to the adjustment stage control unit 701 based on the input operation of the return instruction on the operation unit 7017. The adjustment stage control unit 701 drives the adjustment stage 71 based on the return instruction to move (return) the display unit A to the standby position (step S24).

  In FIG. 19, the processing operation from steps S16 to S21 in FIG. 16, that is, the projector 5 is mounted on the display unit A at the standby position (see FIG. 19F), and the display unit A is moved to the adjustment work position (See (G).) The projector 5 is driven at the adjustment work position to project an image on the projection surface E11a of the front screen mechanism E1 of the display unit A (see (H)), to the projection surface E11a. The projected image captured is captured by the camera 76 and displayed on the display unit 7016 (see (I) in the figure), and the tilt adjustment unit is input based on an instruction input from the operation unit 7017 by the operator while viewing the displayed captured image. A flow of processing for adjusting the inclination of the projector 5 (see (J) in the same figure) by 74 is schematically shown.

  In the image projection process (step S19 in FIG. 16) shown in (H) of FIG. 19, the integrated adjustment control unit 7012 drives the projector 5 through the image projection control unit 707, and for example, an image (projection Emit the mapping image). The image emitted from the projector 5 is reflected by the reflection mirror B32 and projected on the projection surface E11a of the front screen mechanism E1. At this time, the camera 76 captures an image (projected image) projected on the projection plane E11a, and sends the imaging output to the imaging control unit 706.

  In the process of imaging and displaying the projection image shown in (I) of FIG. 19 (step S20 of FIG. 16), the integrated adjustment control unit 7012 outputs an imaging output of the camera 76 (the projection plane E11a in FIG. 20) The captured image of the projected image that has been projected is captured, and this captured image (the projected image and the image of the projection plane E11a) is displayed on the display unit 7016.

  In the inclination adjustment process (step S21 of FIG. 16) shown in (J) of FIG. 19, the integrated adjustment control unit 7012 controls the inclination adjustment unit 74 through the inclination adjustment control unit 704 based on the input operation of the inclination adjustment instruction on the operation unit 7017. The three double adjustment wrenches 745 provided on the drive are driven to adjust the corresponding three double nuts B275 on the base member B22 (see FIG. 9). At this time, the tilt adjustment control unit 704 operates the second wrench 7451 and the first wrench 7455 separately for every three double adjustment wrenches 745 and controls the adjustment nut B 274 and the fixing nut B 273 to be separately tightened. .

  FIG. 22 is an explanatory view showing a tightening mode of the double nut B 275 by the double adjustment wrench 745, and FIG. 22 (a) shows a tightening mode of the adjustment nut B 274, and FIG. 22 (b) is a fixing nut B273. The tightening mode of In the inclination adjustment shown in (J) of FIG. 19, the inclination adjustment control unit 704 first makes the corresponding double nuts B 275 respectively correspond to the second wrench 7451 of the three double adjustment wrenches 745 as shown in FIG. The adjustment nut B 274 is rotationally driven.

  Thereby, the distance between the base member B22 and the mounting plate B20 is adjusted at the position of each double nut B275, and the inclination of the projector 5 attached to the lower surface of the mounting plate B20 is adjusted. By performing this adjustment process until the projection image displayed on the display unit 7016 is projected to the appropriate position of the projection surface E11a of the front screen mechanism E1, the projector 5 is adjusted to an inclination that allows appropriate projection. Can.

  More specifically, the tilt of the projector 5 can be adjusted by the tightening position of the three double nuts B275. For example, as shown in FIG. 9 (b), all double nuts are screwed to the screw of the spacer shaft B271 so that the base member B22 and the mounting plate B20 become almost parallel as shown in FIG. By loosening B275 evenly, the projector 5 can be moved upward, and conversely, when all double nuts B275 are tightened uniformly from the above state, the projector 5 can be moved downward. Therefore, the adjustment operation of the double nut B 275 at this time enables position adjustment in the Y-axis direction on the XYZ axes shown in FIG. 9 of the projector 5.

  For example, only the double nut B275 on the right side is tightened toward the figure from the state in which the three double nuts B275 are screwed to the screws of the spacer shaft B271 in the state as shown in FIG. And the projector 5 can be tilted to the right toward the figure, and conversely, only the double nut B275 on the left toward the figure is tightened (or the two right By loosening only the heavy nut B 275), the projector 5 can be tilted to the left toward the figure. Therefore, the adjustment operation of the double nut B 275 at this time enables the rotation adjustment in the Z-axis direction on the XYZ axes shown in FIG. 9 of the projector 5.

  Thus, for example, the projection image is moved by moving the projector 5 in the Y-axis direction as described above in a state where the projection image is projected at the position indicated by the dotted line in FIG. Can be projected to the height position shown by the solid line in FIG. Further, after adjusting so that the projection state of FIG. 23 (a) is obtained, the projection image is further moved as shown by the solid line in FIG. 23 (b) by performing the adjustment operation of rotating the projector 5 around the Z axis as described above. It is possible to project with the inclination corrected with respect to the projection plane E11a as indicated by.

  After performing adjustment in the Y-axis direction and θ adjustment (rotational adjustment about the Z-axis) of the projector 5 according to the amount of tightening of the adjustment nuts B274 of each double nut B275 by the method described above, three double adjustments By tightening the fixing nuts B 273 of the corresponding double nuts B 275 onto the adjusting nuts B 274 with a wrench 745, the adjusting nuts B 274 can be fixed so as to maintain their positions. As described above, in the present embodiment, the integrated adjustment control unit 7012 controls the position of the projector 5 and the optical axis of the projection light for adjustment based on the position adjustment instruction (attachment position adjustment instruction, tilt adjustment instruction) received by the operation unit 7017. Adjustment of fixing part (mounting screw B 223) by fixing part adjusting means (mounting position adjusting unit 73) so that rotation can be adjusted and adjustment of multiple double nuts B 275 by multiple double nut adjusting means (tilt adjusting unit 74) And adjustment control means for performing control of

  21 shows the processing operations of steps S22 and S23 in FIG. 16, that is, the captured image displayed on the display unit 7016 (for the projection processing of an image and the display processing of the captured image, see FIGS. (H) and (I): 19 (H) and (I) show the mounting position of the projector 5 by the mounting position adjustment unit 73 based on the instruction input from the operation unit 7017 by the operator while looking at (H) and (I) in FIG. Adjustment is performed (see (K1) and (K2) in the figure), and after adjustment of the mounting position is completed, the flow of processing for returning the display unit A to the standby position (see (L) in the drawing) is schematically shown. There is.

  In the position adjustment process (first process) shown in (K1) of FIG. 21, the integrated adjustment control unit 7012 instructs the attachment position adjustment control unit 703 to perform the attachment position adjustment based on the input operation of the attachment position adjustment instruction on the operation unit 7017. The attachment position adjustment control unit 703 drives the four electric drivers 735 of the attachment position adjustment unit 73, and the four attachment screws B223 for fixing the base member B22 of the projector mechanism B2 are unscrewed with the screw holes B251. Rotate in the direction (see FIG. 9).

  As a result, the base member B22 is maintained in a state where it can move by an allowance with respect to the mounting screw B223 of the hole diameter of the position adjustment hole B222 of the mounting piece B221. In the position adjustment process (second process) shown in (K2) of FIG. 21, the integrated adjustment control unit 7012 sends the adjustment stage control unit 701 in a state where the base member B22 can move as described above. Send position movement instruction. As a result, the adjustment stage control unit 701 drives the first adjustment stage 71A of the adjustment stage 71, and the arm units 7150 and 7150 hold the four positions (the holding positions B225 shown in FIG. 9) of the base member B22 and then the projector mechanism. The mounting position of the projector 5 can be adjusted by moving B2 in the X direction on the XYZ coordinates in FIG. 9, for example.

  As a specific example, for example, a state in which the projection image is moved in the Y-axis direction as shown in FIG. 23A, and rotation about the Z-axis is performed at the position after the movement as shown in FIG. Thus, the projector 5 can be moved and adjusted in the X-axis direction so that the projection image is on the proper projection position of the projection surface E11a as shown in FIG. 23C.

After completion of the position adjustment process (second process) shown in (K2) of FIG. 21, the integrated adjustment control unit 7012 determines the four electric drivers of the attachment position adjustment unit 73 based on the input operation of the fixing instruction by the operation unit 7017. The projector mechanism B2 is fixed to the fixing members B25 and B26 by driving 735 and rotating the four attachment screws B223 for fixing the base member B22 of the projector mechanism B2 in the direction in which the screw engagement with the screw hole B251 is tightened.
Thereafter, in the return processing shown in (L) of FIG. 21, the integrated adjustment control unit 7012 sends a return instruction to the adjustment stage control unit 701 based on the input operation of the return instruction on the operation unit 7017, and the adjustment stage control unit 701 The adjustment stage 71 is driven based on the return instruction to move the display unit A to the standby position (return).

  By the series of optical mechanism position adjustment processing shown in FIG. 16 (refer to the operation image shown in FIG. 17, FIG. 19 and FIG. 21) for the display unit A before mounting in the gaming machine 1; It is possible to assemble the display unit A in which the position of the projector 5 and the rotation of the adjustment projection light with respect to the optical axis are adjusted.

  Each display unit A assembled through the above-described optical mechanism position adjustment is then incorporated into the cabinet 21 of the gaming machine 1 and commercialized as the gaming machine 1. At this time, as described above, the display unit A incorporated in the gaming machine 1 is incorporated because the adjustment of the angle of the reflecting mirror B 32 and the position and rotation of the projector 5 are adjusted by the optical mechanism position adjusting device 7. The adjustment operation of the reflection mirror B 32 and the projector 5 after this can be greatly reduced.

  As described above, the optical mechanism position adjusting device 7 according to the present embodiment moves the display unit A without the projector 5 mounted on the adjustment stage 71 and moves it, and measures the laser from the opening for incorporating the projector 5 The measurement unit 75 having the detector 6 is inserted into the display unit A, and then the reflected light by the reflection mirror B 32 of the emitted light (laser) emitted from the laser measuring device 6 is measured by the laser measuring device 6 A mirror adjustment unit 72 is provided to adjust the position of the reflection mirror B32 based on the result.

  Thereby, the position of the reflection mirror B32 can be adjusted in accordance with the position of the display unit A. Therefore, since the reflecting mirror B 32 is in the proper position, it is possible to eliminate individual differences in positional deviation of the optical mechanism of the display unit A excluding the projector 5.

  In addition, the optical mechanism position adjusting device 7 according to the present embodiment temporarily mounts the projector 5, captures and displays a projection image projected by the projection surface E11a of the front screen mechanism E1 from the projector 5, and displays the displayed image. An inclination adjustment unit 74 for adjusting the inclination of the projector 5 by receiving an inclination adjustment instruction while viewing the image and an attachment position adjustment instruction, and rotating the double nut B 275 with the double adjustment wrench 745 based on the inclination adjustment instruction. The mounting position adjustment unit 73 adjusts the mounting position of the projector 5 by releasing the fixing of the projector 5 by the electric driver 735 and making it movable based on the mounting position adjustment instruction.

  Thus, using the mounting position adjustment unit 73 and the inclination adjustment unit 74, the position and rotation of the projector 5 can be adjusted to an appropriate position with respect to the projection surface based on the projection image with respect to the projection surface E11a.

  In the present embodiment, the operator adjusts the tilt of the projector 5 using the operation unit 7017 while observing how much the projected image displayed on the display unit 7016 and the image on the projection surface E11a of the front screen mechanism E1 overlap. The integrated adjustment control unit 7012 performs the input operation of the instruction and the attachment position adjustment instruction, and the integrated adjustment control unit 7012 performs the double adjustment wrench 745 and the attachment position adjustment unit of the adjustment unit 74 based on the inclination adjustment instruction and the attachment position adjustment instruction input by the input operation. A case is described in which the electric driver 735 of 73 is driven to perform inclination adjustment and mounting position adjustment of the projector 5 (manual adjustment). However, the present invention is not limited to this, and the tilt adjustment and the attachment position adjustment of the projector 5 can be automatically performed (automatically adjusted).

  In the case of automatically adjusting the inclination and mounting position of the projector 5, for example, the integrated adjustment control unit 7012 controls the overlap between the projection image from the projector 5 captured by the camera 76 and the image on the projection surface E11a of the front screen mechanism E1. On the basis of the check result, the inclination adjustment instruction and the attachment position adjustment instruction for making it possible to project the projection light from the projector 5 to an appropriate position on the projection surface E11a. The inclination adjustment control unit 704 and the attachment position adjustment control It is sufficient to feed to the portion 703 and drive-control the double adjustment wrench 745 of the inclination adjustment unit 74 and the electric driver 735 of the mounting position adjustment unit 73.

  As described above, according to the present invention, either the configuration in which the operator visually adjusts (manually adjusts) the inclination and the mounting position of the projector 5 or the configuration in which the adjustment is performed automatically can be applied. Display means (for example, the display unit 7016 or the function of displaying the pickup image on the display unit 7016) for displaying the projection image picked up by the camera is necessary only in the case of the above-mentioned manual adjustment. The display means is not necessary for

As understood from the structure shown in FIG. 13 and the description of steps S21 and S22 in FIG. 16, the first adjustment stage 71A is connected to the gripping means (a pair of side members 713A and 713A), and the arm portion of the gripping means The position of the projector 5 and the optical axis of the projection light for adjustment are fixed to the projector 5 held by 7150 and 7150 by the fixed part adjustment means (attachment position adjustment unit 73) and the plurality of double nut adjustment means (tilt adjustment unit 74). And rotation relative to the display unit A so as to be adjustable.

  As described above, by dividing one adjustment stage 71 in the vertical direction, only the projector 5 mounted on the display unit A can be operated without moving the display unit A. . Therefore, even if positional deviation occurs in, for example, a reflection mirror of the projector 5 mounted on the display unit A, position adjustment is performed on the adjustment stage 71 without lowering the display unit A from the adjustment stage 71. Can.

  In addition, the optical mechanism position adjusting device 7 according to the present embodiment is fixed as an adjusting jig of a double nut B 275 composed of fixing nuts B 273 and adjusting nuts B 274 having different diameters for adjusting the inclination of the projector 5. A first wrench 7455 having a first wrench portion 7456 which can be fitted to the nut B273, and a second wrench portion 7452 which axially movably accommodates the first wrench 7455 and which can be fitted to the adjusting nut B274 It has a double adjustment wrench 745 consisting of a second wrench 7451 having the same.
