Description

The present invention relates to a game machine.

Conventionally, a plurality of reels on which a plurality of symbols are drawn on the peripheral surface, and a display window for displaying a part of the symbols drawn on the peripheral surface of each reel while being provided in plurality corresponding to each of these reels. A reel-type gaming machine (so-called "pachislot machine") is known. In such a game machine, all reels are rotated based on the player's input of game value (game medium) such as a medal and the start operation on the start lever, and each reel is based on the stop operation on the stop button by the player. By stopping the rotation of the symbol, the design is stopped and displayed on the display window.

In such a game machine, the combination of symbols related to the "combination" is stopped and displayed on the effective line in the display window, and the player is determined as the display combination (that is, the "combination" is established). A privilege (for example, a medal) is given to the person.

In addition, this type of game machine is equipped with a display unit such as a liquid crystal panel, and it is possible to produce a wide variety of effects by images as well as the effects of light by lamps and sounds by speakers. It is effective as a method to raise the expectations of the player for the development of the game.

However, a display unit such as a liquid crystal panel is expensive, which has been a factor that hinders the cost reduction of game machines.

Therefore, in recent years, as a technique for enlarging the display screen for displaying a moving image for a game, a technique has been proposed in which a liquid crystal projector, which is cheaper than a liquid crystal panel, is used (see, for example, Patent Document 1).

In this proposal, in a game machine such as a slot machine, a liquid crystal projector that projects a game movie on a built-in small liquid crystal panel and magnifies and projects it is arranged at the lower part of the inside, and the projected light of the liquid crystal projector is received on the back side. Therefore, in order to project the game moving image on the front side, a screen that transmits this projected light to the front side is arranged on the front side as a display screen.

Further, in a game machine such as a slot machine, it has been proposed that the image on the rear side of the reel captured by the video camera unit is projected on the front side of the reel by a projector when a predetermined condition is satisfied. (See, for example, Patent Document 2). In the proposed gaming machine, projectors are provided on each of the three reels and are located on top of the corresponding reels. Further, the projector is configured to irradiate the light of the image toward the front side of the game machine and project the light onto the reel by the half mirror.

Next, the circuit configuration of the game machine 1 including the main control circuit 60 or the sub control circuit 70 will be described with reference to FIGS. 7 and 8.

FIG. 7 shows an example of a circuit configuration of the game machine 1 according to the present embodiment.

The main control circuit 60 controls the progress of a series of games, such as determining the internal winning combination and controlling the rotation of the reels 3L, 3C, and 3R. The main control circuit 60 is configured by using a microcomputer 30 arranged on a circuit board as a main component and adding a circuit for random number sampling to the main component. The microcomputer 30 is composed of a main CPU 31, a main ROM 32, and a main RAM 33.

A clock pulse generation circuit 34, a frequency divider 35, a random number generator 36, and a sampling circuit 37 are connected to the main CPU 31.

The main CPU 31 determines the internal winning combination based on the random number value and the internal lottery table (not shown), and the reels 3L, 3C, 3R are based on the internal winning combination and the timing at which the stop operation is detected. Stop the rotation of. Further, when the rotation of the reels 3L, 3C, and 3R is stopped, the main CPU 31 determines whether or not the "combination" is established based on the combination of the symbols displayed on the main display window 4, and determines whether or not the "combination" is established. ”Is established, the player is given a profit such as paying out medals according to the established“ winning combination ”.

The clock pulse generation circuit 34 and the frequency divider 35 generate a reference clock pulse. The random number generator 36 generates random numbers in the range of “0” to “65535”. The sampling circuit 37 extracts (samples) one random number value from the random numbers generated by the random number generator 36.

Further, in the game machine 1, the extracted random number value is stored in the random number value storage area of the main RAM 33. Then, based on the random number value stored in the random number value storage area of the main RAM 33 for each unit game, the internal winning combination is determined in the internal lottery process.

As a means for random number sampling, the random number sampling may be executed in the microcomputer 30, that is, on the operation program of the main CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, but they can be left as a backup for the random number sampling operation.

The main ROM 32 of the microcomputer 30 stores programs and various tables related to the processing of the main CPU 31.

Various information obtained by the processing of the main CPU 31 is set in the main RAM 33. For example, information for specifying the extracted random number value, game state, internal winning combination, number of payouts, bonus carry-over status, set value, etc., various counters, and flags are set. A part of this information is transmitted to the sub-control circuit 70 by various commands.

Major peripheral devices whose operation is controlled by a control signal from the microcomputer 30 include a hopper 40, stepping motors 49L, 49C, 49R and the like. The transmission and reception of signals between these actuators and the main CPU 31 is performed via the I / O port 38.

Each circuit includes a lamp drive circuit 45, a display unit drive circuit 48, a motor drive circuit 39, and a hopper drive circuit 41.

The lamp drive circuit 45 controls a lighting pattern (lighting / extinguishing, etc.) of, for example, a WIN lamp 23 provided on the front door 2b of the game machine 1 and a maximum BET lamp 9.

The display unit drive circuit 48 controls, for example, a bonus game information display unit (not shown) and a push order display (not shown) in addition to the payout number display unit 11 and the credit display unit 17. The push order display is for displaying, for example, the push order of the stop buttons 7L, 7C, 7R that are stopped during the RT3 game state on the display screen of the liquid crystal display device 20.

The hopper drive circuit 41 drives and controls the hopper 40. As a result, the medals housed in the hopper 40 are paid out.

The motor drive circuit 39 drives and controls the stepping motors 49L, 49C, 49R. As a result, the reels 3L, 3C, and 3R are rotated and stopped. The motor drive circuit 39 and the stepping motors 49L, 49C, 49R that perform such control constitute the symbol display control means of the present invention.

Further, each switch and each circuit for generating an input signal that triggers the output of a control signal to each of the above-mentioned circuits and peripheral devices are connected to the input unit of the microcomputer 30. Examples of the switch and each circuit include a start switch 6S, a stop switch 7LS, 7CS, 7RS, a maximum BET switch 8S, a C / P switch 13S, a medal sensor 5S, a reel position detection circuit 50, and a payout completion signal circuit 51.

The start switch 6S detects the player's start operation (game start operation signal) with respect to the start lever 6, and outputs the game start command signal for commanding the start of the game to the microcomputer 30.

The stop switches 7LS, 7CS, and 7RS detect the player's stop operation on the stop buttons 7L, 7C, and 7R, respectively, and stop the rotation of the reels 3L, 3C, and 3R corresponding to the detected stop buttons 7L, 7C, and 7R. The stop command signal to be commanded is output to the microcomputer 30.

The stop switches 7LS, 7CS, and 7RS are also collectively referred to as the stop switch 7S.

The maximum BET switch 8S detects a player's insertion operation (pressing operation) for the maximum BET button 8 and outputs a signal instructing the insertion of medals from the credited medals to the microcomputer 30.

The C / P switch 13S detects the switching operation of the player and outputs a signal for switching the credit mode or the payout mode to the microcomputer 30. Further, when the credit mode is switched to the payout mode, a signal instructing the payout of the medals credited in the game machine 1 is output to the microcomputer 30.

The medal sensor 5S detects the medal inserted into the medal insertion slot 5 by the player's insertion operation, and outputs a signal indicating that the medal has been inserted to the microcomputer 30.

The reel position detection circuit 50 detects a pulse signal from a reel rotation sensor (not shown) and generates a signal for detecting the position of a symbol on each reel 3L, 3C, 3R.

The payout completion signal circuit 51 indicates that the payout of medals is completed when the number of medals detected by the medal detection unit 40S (that is, the number of medals paid out from the hopper 40) reaches a specified number. Generate a signal to indicate.

The sub-control circuit 70 is connected to the I / O port 38 and performs various processes such as determination and execution of production data based on various commands output from the main control circuit 60 such as a start command.

However, the sub control circuit 70 does not output commands or information to the main control circuit 60, and communication is performed in one direction from the main control circuit 60 to the sub control circuit 70.

Major peripheral devices whose operation is controlled by a control signal from the sub-control circuit 70 include a liquid crystal display device 20 including a liquid crystal display panel 20a and a touch sensor panel 20b, detectors 22, 22, speakers 25L, 25R, and the like. There is a display unit 100 including the projector 101, and an accessory driving unit 200 for driving the accessory 202.

Based on the determined effect data, the sub-control circuit 70 determines the effect information displayed on the display unit 100 and displays the effect information, and determines the game sound output from the speakers 25L and 25R and controls the output thereof. ..

Further, the sub-control circuit 70 determines and displays game information and the like displayed on the liquid crystal display panel 20a of the liquid crystal display device 20 as the game progresses, and detects input from the touch sensor panel 20b. Take control.

Further, the sub-control circuit 70 draws out the effect pattern number when the specific winning combination is internally won, and determines the effect data accompanying the transition to the specific advantageous state.

Here, in the game machine 1 according to the present embodiment, when a signal to start the game is output from the start switch 6S by the operation of the player with respect to the start lever 6 on condition that a medal is inserted, the motor drive circuit 39 A control signal is output to, and the rotation of the reels 3L, 3C, 3R is started by the drive control of the stepping motors 49L, 49C, 49R (for example, excitation to each phase). At this time, the number of pulses output to the stepping motors 49L, 49C, 49R is counted, and the counted value is set in a predetermined area of the main RAM 33 as a pulse counter.

In this game machine 1, when the pulse of "16" is output, the reels 3L, 3C, and 3R move by one symbol. The number of moved symbols is counted, and the counted value is set in a predetermined area of the main RAM 33 as a symbol counter. That is, every time the pulse counter counts "16" pulses, the symbol counter is updated by "1".

Further, a reel index is obtained from the reels 3L, 3C, and 3R for each rotation, and data related to the reel index is output to the main CPU 31 via the reel position detection circuit 50. By outputting the data related to the reel index, the values of the pulse counter and the symbol counter set in the main RAM 33 are cleared to "0".

In this way, for each reel 3L, 3C, 3R, the symbol position within the range of one rotation is specified.

The distance that each symbol moves by one symbol due to the rotation of the reels 3L, 3C, and 3R is called one frame. That is, the movement of the symbol by one frame corresponds to the update of the symbol counter by "1".

A symbol arrangement table (not shown) is stored in the main ROM 32 in order to associate the rotation positions of the reels 3L, 3C, and 3R with the symbols drawn on the outer peripheral surface of the reel. This symbol arrangement table is a code from "00" to "20" that is sequentially assigned for each fixed rotation pitch of each reel 3L, 3C, 3R based on the position where the data related to the reel index is output. A number (symbol position) is associated with a symbol code that identifies the type of symbol provided corresponding to each code number.

Further, when the game start command signal is output from the start switch 6S, the random number value is extracted by the random number generator 36 and the sampling circuit 37. In the game machine 1, when the random number value is extracted, the random number value is stored in the random number value storage area of the main RAM 33. Then, the internal winning combination is determined by the main CPU 31 based on the random number value stored in the random number value storage area.

After the reels 3L, 3C, and 3R reach a constant speed rotation, the stop switch 7L pattern is combined by the stop operation, and the second priority is the combination of the symbols related to the "small combination". Next, the third priority is the combination of symbols related to "bonus".

Here, when the stop operation is detected by the stop switches 7LS, 7CS, 7RS, the symbol position corresponding to the symbol counter of the corresponding reels 3L, 3C, 3R, that is, the stop of rotation of the reels 3L, 3C, 3R is stopped. The symbol position to be started is called the "stop start position", and the determined number of sliding frames (numerical range "0" to "4") is added to the stop start position, that is, the reels 3L, 3C, 3R. The position of the symbol that stops the rotation is called the "scheduled stop position". The number of slip frames is the amount of rotation of the reels 3L, 3C, 3R from the time when the stop operation is detected by the stop switches 7LS, 7CS, 7RS until the rotation of the corresponding reels 3L, 3C, 3R is stopped. In the machine 1, the maximum number of sliding frames is defined as "4".

When the rotation of all the reels 3L, 3C, and 3R is stopped, the display combination search process, that is, the winning / failure determination process of the establishment / non-establishment of the "combination" is performed based on the combination of the symbols displayed on the effective line. The search for the display combination is performed based on the symbol combination table (not shown) stored in the main ROM 32. In this symbol combination table, a combination of symbols related to the display combination and a payout (number of medals to be paid out) corresponding to the combination of symbols are set.

When it is determined by the search for the display combination that the combination of symbols related to the winning is displayed, a control signal is output from the main CPU 31 to the hopper drive circuit 41, and the medals are paid out by driving the hopper 40. At this time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 40, and when the counted value reaches a specified number, the payout completion signal circuit 51 sends a signal indicating the completion of medal payout to the main CPU 31. Is output to. As a result, the main CPU 31 outputs a control signal to the hopper drive circuit 41, and the drive of the hopper 40 is stopped.

When the C / P switch 13S is used to switch to the credit mode, the main CPU 31 determines that the combination of symbols related to the winning is displayed, and credits the main RAM 33 with the number of payouts according to the combination of the symbols related to the winning. Add to the counter. Further, the number of medals paid out is displayed as the number of updated credits on the credit display unit 17 and displayed on the payout number display unit 11 by controlling the display unit drive circuit 48 by the main CPU 31. ..

Here, the payout or credit of medals, which is performed when the combination of symbols related to the winning is displayed, may be collectively referred to as “payout”.

In the present embodiment, based on the determination of the internal winning combination in the main control circuit 60, the sub-control circuit 70, which will be described later, selectively draws the effect pattern numbers. That is, the lottery of the effect pattern number is performed on the condition that a specific winning combination as the internal winning combination, which is notified by the start command from the main control circuit 60, has been internally won (a predetermined effect condition is satisfied).

Next, the circuit configuration of the sub-control circuit 70 will be described with reference to FIG.

FIG. 8 shows a configuration example of the sub-control circuit 70 of the game machine 1 according to the present embodiment.

The sub-control circuit 70 uses video, sound, light, and the like to perform control for notifying effects and various information related to the game. That is, the sub control circuit 70 determines the effect data and performs various effect processes based on various commands and various input information transmitted from the main control circuit 60.

In addition, the drive control of the accessory drive unit 200 is performed.

Specifically, the sub CPU 71 receives various commands from the main control circuit 60 and stores various information included in the commands in the sub RAM 73. All information in the main control circuit 60 is transmitted by a command, and the sub control circuit 70 can determine the state of the main control circuit 60 one by one.

Further, the sub CPU 71 executes a program while referring to the game state information and the internal winning combination information stored in the sub RAM 73, thereby executing the liquid crystal display device 20, the speakers 25L, 25R, the detectors 22, 22, and the display unit. The content of the effect to be performed by the 100 and the accessory drive unit 200 is determined.

Further, the sub CPU 71 controls the liquid crystal display device 20 via the GPU 75, and controls the speakers 25L and 25R via the DSP 78 and the amplifier 79, based on the effect data according to the determined effect content.

Further, the sub CPU 71 controls the projector 101 of the display unit 100 based on the effect data according to the content of the determined effect, and also controls the accessory 202 via the accessory drive unit 200. It is also possible to provide a display unit drive unit and change the position of the projector 101 by controlling from the sub CPU 71.

Further, the sub CPU 71 acquires a random number value to be used when determining the effect data or the like by executing the random number acquisition program stored in the sub ROM 72. However, similarly to the main control circuit 60, when the random number generator and the sampling circuit are provided in the sub control circuit 70, the processing is not necessary.

The sub ROM 72 has a program storage area for storing a program executed by the sub CPU 71 and a data storage area for storing various tables and the like.

The program storage area stores an operating system, a device driver, a control program for inter-board communication processing for controlling communication with the main control circuit 60, an effect data registration process for determining the content of the effect, and the like.

On the other hand, the data storage area includes a table storage area that stores an effect lottery table (not shown), a drawing control data storage area that stores animation data such as character object data, and a sound that stores sound data such as BGM and sound effects. It has a control data storage area and the like.

The sub RAM 73 is used as a temporary storage means for work when the sub CPU 71 executes each program.

The SRAM 74 is used as a storage means for holding the data used by the sub CPU 71.

The GPU 75 performs processing for displaying game information on the liquid crystal display device 20 and the projector 101 based on an image display command or the like received from the sub CPU 71. The GPU 75 temporarily stores image data and the like in the VRAM 76 as needed.

The DSP 78 transmits digital sound data selected by the sub CPU 71 based on the effect data to the amplifier 79. The amplifier 79 amplifies the sound data received from the DSP 78 based on the volume adjusted by the volume adjusting knob (not shown) provided in the game machine 1, and then transmits the sound data to the speakers 25L and 25R. As a result, the game sound corresponding to the effect data determined by the sub CPU 71 is output from the speakers 25L and 25R. Here, the amplifier 79 is, for example, a digital amplifier.

In the above-described embodiment, the display unit 100 using the projector 101 can be efficiently arranged in the limited space of the existing game machine 1, so that the game has a simple structure but is inexpensive. It becomes possible to provide the machine 1. That is, since the display unit 100 using the projector 101 can be mounted in place of the conventional display unit using the liquid crystal, the game machine 1 is large without significantly changing the design of the existing game machine. It can be suppressed from becoming. Therefore, even if a display unit such as a liquid crystal panel, which is relatively expensive and whose price may fluctuate greatly depending on the time of purchase, is not used, a wide variety of display units 100 using a cheaper projector 101 are used. It is possible to realize a stable production.

Further, since the projector 101, the reflector 102, and the screen 103 are integrated as a detachable unit with respect to the cabinet 2a of the game machine 1, the display unit 100 can be made versatile.

Further, since the accessory 201 having a three-dimensional shape and the movable accessory 202 can be arranged between the screen 103 and the display screen area 19, the effect mode is three-dimensional, and a more novel effect can be achieved. It is possible to perform an impressive production.

May be used.

Further, in the ninth embodiment of the present invention, the rotational movement of the gear 1144 by the focus adjustment motor (stepping motor) 1107 is transmitted to the lead screw 1146, and the projection lens engaging portion 1148 fitted to the lead screw 1146 is transmitted. Although the projection lens 1143 is configured to be moved in the optical axis direction by the linear movement of the above, the projection lens 1143 is moved in the optical axis direction by utilizing the rotation by the motor by the focus adjustment mechanism having various other configurations. be able to. For example, the movement of the projection lens can be realized by moving the rack gear using a worm gear connected to the motor. The technical idea of the present invention can be applied to the focus adjustment mechanism having such various configurations.

Further, in the ninth embodiment of the present invention, focus adjustment is realized by moving the projection lens 1143 itself in the optical axis direction, but focus adjustment is realized by moving a predetermined lens by various mechanisms and methods. can do. For example, in the case where the focus adjustment of the projection lens 1143 is performed by the focus ring, the focus ring can be displaced by a stepping motor or the like to move the projection lens 1143 in the optical axis direction.

Next, in the display unit 100H according to the ninth embodiment of the present invention, a method of attaching a pedestal related to the position adjustment of the projector 1101 will be described.

The holding method is the same as in FIG. 39 (a), the upper view of FIG. 39 (b) is a view of the mounting position in the housing mounting hole 1201a from above, and the lower view of FIG. 39 (b) is a view from above. , FIG. 39 (b) is a cross-sectional view taken out by a straight line of DD'. In this state, the screw shaft of the mounting screw 1251a can be moved within the range (adjustment range) of the shaded portion indicated by the reference numeral C as a result of shifting the mounting pedestal 1121.

Although FIG. 39 shows the mounting state of the housing mounting holes 1201a, the same applies to the other housing mounting holes 1201b to 1201d. In this way, the mounting pedestal 1121 can be moved relative to the ceiling plate 1300a of the display unit 100H to adjust its position within a predetermined adjustment range. The mounting pedestal 1121 is held in a state of facing (parallel facing) the ceiling plate 1300a, and its position can be displaced two-dimensionally within the adjustment range.

FIG. 40 shows a method of mounting the mounting pedestal 1121 and the adjusting pedestal 1122 in the display unit 100H. FIG. 40A is a cross-sectional view showing a state in which the adjusting pedestal 1122 is supported by the mounting pedestal 1121 by the adjusting screw 1211a and the mounting screw 1221a at the first mounting position.

Further, a spring 1222a is arranged around the screw shaft between the mounting pedestal 1121 and the adjusting pedestal 1122. The spring 1222a urges the mounting pedestal 1121 and the adjusting pedestal 1122 in a direction away from each other. The nut 1223a functions to keep the adjusting pedestal 1122 within a certain range on the screw shaft of the mounting screw 1221a, and this can be realized by using various other mechanisms. Further, the nut 1223a is fixed to the adjusting pedestal 1122 by some method so that the positional relationship between the mounting screw 1221a and the adjusting pedestal 1122 does not change (so that the screw portion of the mounting screw 1221a fits into the adjusting pedestal 1122). May be).

The adjusting screw 1211a is a Phillips screw screwed into the mounting pedestal 1121 arranged in the vicinity of the mounting screw 1221a. By turning the adjusting screw 1211a, the tip of the screw shaft comes into contact with the adjusting pedestal 1122, the distance between the mounting pedestal 1121 and the adjusting pedestal 1122 is changed, and as a result, the position of the adjusting pedestal 1122 can be adjusted. Since the mounting pedestal 1121 and the adjusting pedestal 1122 are urged by the spring 1222a, a loosening prevention function at the screwed portion between the adjusting screw 1211a and the mounting pedestal 1121 is realized.

FIG. 40A shows the mounting state with respect to the first mounting position, but the same applies to the second mounting position and the third mounting position. In this way, since the adjustment pedestal 1122 can be finely adjusted by the adjustment screws at each of the three mounting positions, the position (posture) of the adjustment pedestal 1122 is adjusted with respect to the mounting pedestal 1121 in three dimensions of the XYZ axes. For example, it is possible to adjust the tilt (adjustment of trapezoidal distortion).

FIG. 40B shows a mounting method different from that shown in FIG. 40A. At the first mounting position, the adjusting pedestal 1122 is supported by the mounting pedestal 1121 by the adjusting screw 1271a and the mounting screw 1281a. It is sectional drawing which shows the state.

The mounting screw 1281a penetrates the mounting pedestal 1121 and the adjusting pedestal 1122 without being screwed, and the screw shaft of the mounting screw 1281a is screwed into the nut 1283a on the lower side of the adjusting pedestal 1122. A spring 1282a is arranged around the screw shaft between the mounting pedestal 1121 and the adjusting pedestal 1122. The spring 1282a urges the mounting pedestal 1121 and the adjusting pedestal 1122 in a direction away from each other. The nut 1283a functions to keep the adjusting pedestal 1122 within a certain range on the screw shaft of the mounting screw 1281a, and this can be realized by using various other mechanisms. Further, the screw head of the mounting screw 1281a is fixed to the mounting pedestal 1121 by some method so that the positional relationship between the mounting screw 1281a and the mounting pedestal 1121 does not change (the screw shaft close to the screw head of the mounting screw 1281a). A screw groove may be provided in the portion so that this portion and the mounting pedestal 1121 may be fitted to each other).

The adjusting screw 1271a is a Phillips screw screwed into the adjusting pedestal 1122, which is arranged close to the mounting screw 1281a. By turning the adjusting screw 1271a, the tip of the screw shaft comes into contact with the mounting pedestal 1121 and the distance between the mounting pedestal 1121 and the adjusting pedestal 1122 is changed, and as a result, the position of the adjusting pedestal 1122 can be adjusted. Since the mounting pedestal 1121 and the adjusting pedestal 1122 are urged by the mounting screw 1281a and the spring 1282a, a loosening prevention function at the screwed portion between the adjusting screw 1271a and the adjusting pedestal 1122 is realized. In the example, a nut 1272a is further provided between the screw head of the adjusting screw 1271a and the adjusting pedestal 1122 to fix the screwed portion between the adjusting screw 1271a and the adjusting pedestal 1122, and realize a higher level of loosening prevention function. ing.

Although FIG. 40 (b) shows the mounting state regarding the first mounting position, the same applies to the second mounting position and the third mounting position. In this way, since the adjustment pedestal 1122 can be finely adjusted by the adjustment screws at each of the three mounting positions, the position (posture) of the adjustment pedestal 1122 is adjusted with respect to the mounting pedestal 1121 in three dimensions of the XYZ axes. For example, it is possible to adjust the tilt (adjustment of trapezoidal distortion).

As described with reference to FIGS. 37 to 40, two-dimensional position adjustment is possible between the ceiling plate 1300a of the display unit 100H and the mounting pedestal 1121 by mounting methods in the four housing mounting holes. Therefore, the three-dimensional position adjustment between the mounting pedestal 1121 and the adjusting pedestal 1122 is possible depending on the mounting method at the three mounting positions. With such a configuration, the optical axis direction (posture) of the projection lens 1143 of the projector 1101 mounted on the adjustment pedestal 1122 as a base can be adjusted by the above-mentioned two different two-step adjustment steps.

The mounting method of the mounting pedestal 1121 and the adjusting pedestal 1122 can be similarly applied to the mounting of the projector 101 according to the first to eighth embodiments described above.

Next, in the ninth embodiment of the gaming machine according to the present invention, the configuration of the projection target suitable for the projection of the irradiation light by the projector 1101 will be described. As described above, the irradiation direction of the projector 1101 is basically the front direction, the left direction, the right direction, and the downward direction, and the projection target of the irradiation light is, for example, the screen 1303 (front direction) and the left side L. The side plate 1305 (left direction), the side plate 1305 (right direction) of the right side R1, and the stage 1300b (down direction). Further, the movable screen 1304 and the accessory are also projected targets of the irradiation light.

Here, when the irradiation light is projected onto these projection targets, the reflection of the light source can be effectively prevented, and the glare can be suppressed by appropriate diffused reflection to realize a good viewing angle and brightness. A projection target such as a screen 1303 is formed by a predetermined process, or a predetermined coating is applied.

First, the processing of the projection target suitable for the projection of the irradiation light will be described. In order to achieve appropriate performance, the screen to be projected is textured. Wrinkle processing is a process in which wrinkles are formed on the surface. The screen or the like to be projected is molded using a die that has been textured, whereby a wrinkle pattern is formed on the surface of the screen or the like to be projected.

Due to such a wrinkle pattern on the surface, it is possible to effectively prevent the reflection of the light source, and further, it is possible to realize a good reflection of the projected image.

The grain processing includes a pattern called "pear-skin texture", and in the tenth embodiment of the gaming machine according to the present invention, for example, the average depth is about 25 μm to 30 μm and the draft is 3% or more. A certain satin pattern (pear-skin No. 5) is preferable.

Next, painting of the screen or the like to be projected will be described. In order to achieve appropriate performance, a two-layer coating is applied to the screen or the like to be projected. Two-layer coating here means that paints having different characteristics are applied one above the other (in two layers). For example, a high-brightness paint having high reflectivity (for example, 2P-600 silver, which is a metallic paint "ultra-bright silver") is used for the undercoat, and a matte paint (for example, "matte") is used for the topcoat. HG-650 white), which is "white", can be used. Further, about 5% of a matting agent (silica) can be added to HG-650 white.

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

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

In addition, as a topcoat paint, a paint in which glass-based or resin-based beads having various average particle sizes as a matting agent are added in a predetermined ratio to HG-650 white, and a paint in which silica is added in addition to the beads are used. It can also be used. Further, it is also possible to use a paint obtained by adding beads having various average particle diameters as a matting agent to HG-650F clear or HG-650F clear in a predetermined ratio. The film thickness can also be adjusted in various ways, for example, up to 16 to 23 μm. The composition of HG-650F clear is 20 to 30% for resin, 2 to 5% for silica as a matting agent, 0.5 to 2% for additives, and 60 to 70% for solvent.

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

As described above, by forming the screen or the like to be projected by embossing or applying two-layer coating, it is possible to effectively prevent the reflection of the light source and further realize a good projection image. be able to. In addition, the above-mentioned two-layer coating can be applied to a screen or an accessory that has been textured.

Further, the material such as the screen or the accessory to be projected is, in this example, a black or white ABS resin or a transparent polycarbonate resin, but is not limited thereto.

The surface processing and painting of the screen and the accessory to be projected can be similarly applied to the screen and the accessory according to the first to eighth embodiments described above.

Next, in the display unit 100H according to the ninth embodiment of the gaming machine according to the present invention, adjustment (adjustment of the projection position and focus of the irradiation light) regarding the display mode by projecting the irradiation light by the projector 1101 is performed. A method of using the communication function of the projector 1101 and the adjustment PC connected to the projector 1101 will be described. The projector 1101 supported by the ceiling plate 1300a of the display unit 100H checks whether the projection position and focus of the irradiation light match the specifications at the time of shipment at the factory or at the timing when the assembly of the game machine 1 is completed. Is performed, and adjustments are made as necessary.

Therefore, as shown in FIG. 41, the adjustment PC 1301 is a projector of the display unit 100H by a predetermined communication line (for example, serial communication such as UART, RS-232c, USB, Ethernet (registered trademark) (LAN)). It is communicably connected to 1101, and the projection position and focus of the projector 1101 are adjusted by the operation of the adjustment PC 1301 by the factory adjustment person. In this example, the person who performs the adjustment operation is referred to as a factory coordinator for convenience, but the location of the adjustment operation is not limited to the factory.

For this adjustment operation, the adjustment PC 1301 is temporarily connected to the control LSI 1103 of the projector 1101 when performing the adjustment (see FIG. 33). When the factory adjustment person operates the adjustment PC 1301, the projection position and focus of the irradiation light on the projector 1101 are changed by a predetermined command transmitted from the adjustment PC 1301. When the projection position and the focus are correctly adjusted in this way, the displacement data for adjustment is stored in, for example, the EEPROM 1104 of the projector 1101 as offset data with respect to the reference value (see FIG. 33). The EEPROM 1104 is a non-volatile memory, and can store and maintain data without supplying power from the projector 1101 or the like. Therefore, the offset data stored in the EEPROM 1104 can be used as it is even when the power supply to the projector 1101 is temporarily stopped for transportation or the like and the game machine 1 is installed in the game hall.

More specifically, the offset data stored in the EEPROM 1104 includes center adjustment values (that is, vertical (Y-axis) displacement, horizontal (X-axis) displacement), and horizontal adjustment values (X-axis). Includes projection position adjustment data, including offset data (rotation angle to keep the) horizontal. Further, the offset data includes focus adjustment data including offset data such as displacement related to focus adjustment (for example, displacement of aperture value (F value) defining depth of field, displacement of lens position related to focus adjustment, etc.). included.

FIG. 42A shows an outline of the processing at the time of adjusting the projector 1101. As shown in FIG. 42 (a), the adjustment PC 1301 is connected to the control LSI 1103 of the projector 1101, and the pattern image display mode (projection position, etc.) is adjusted by operating the adjustment PC 1301. During this time, the control LSI 1103 controls the DLP control circuit 1105 and the LED driver 1106 (see FIG. 33) based on the read initial setting data 1352, the projection position adjustment data and the focus adjustment data that change due to the adjustment, and the optical unit. A pattern image is projected on the screen of the game machine 1 on 1108. The projection position and focus of the pattern image change according to the adjustment, and the factory coordinator makes adjustments while looking at the projected pattern image. Further, here, the initial setting data 1352 is a reference value set for the operation of the projector 1101, and is stored in, for example, the EEPROM 1104. Further, it can be assumed that the initial setting data 1352 does not exist (adjustment starts from the initial state of the projector 1101).

When the adjustment is completed, the control LSI 1103 stores the adjusted projection position adjustment data 1351a and the focus adjustment data 1351b as offset data 1351 in the EEPROM 1104 under the control of the adjustment PC 1301.

FIG. 42B shows an outline of the processing of the projector 1101 when the game is executed after the adjustment. The control LSI 1103 of the projector 1101 receives the effect image data from the sub-control circuit 70, reads the projection position adjustment data 1351a and the focus adjustment data 1351b stored at the time of adjustment from the EEPROM 1104, and reads these adjustment data and the initial setting data. The received effect image data is processed based on 1352. Then, the control LSI 1103 controls the DLP control circuit 1105 and the LED driver 1106 (see FIG. 33) to project the processed effect image (on the screen of the game machine 1) on the optical unit 1108.

For example, when the vertical (Y-axis) displacement of the initial setting data 1352 is 0 (pixels) and the center adjustment value (vertical (Y-axis) displacement) of the projection position adjustment data 1351a is +5 (pixels). , The effect image data is processed so as to be shifted upward by 5 pixels as a whole, and is controlled to be projected. Here, for example, the effect image data is prepared in a size larger than the size actually projected on the screen or the like (large size in both vertical and horizontal directions), and when the above-mentioned projection position adjustment is performed, the large size range is prepared. The shift process is performed within.

When the focus adjustment data 1351b is, for example, a displacement of the F value, the effect image data is processed and projected by adding the initial setting data 1352. Further, when the focus adjustment data 1351b is, for example, the displacement of the lens position, the initial setting data 1352 is added, and the drive unit 1141 of the optical unit 1108 is controlled accordingly to move the projection lens 1143.

Here, the configuration of the adjustment PC 1301 will be described with reference to FIG. 43. However, the configuration shown in FIG. 43 merely illustrates a typical configuration of the adjustment PC 1301. The same functions as the adjustment PC 1301 can be realized by computers having various other configurations.

The adjustment PC 1301 includes a CPU (Central Processing Unit) 1311, ROM 1312, RAM 1313, projector interface 1314, display controller 1315, display 1316, input device interface 1317, keyboard 1318, mouse 1319, external storage device 1320, and external recording medium drive device 1321. , And a bus 1324 connecting these components to each other.

The CPU 1311 controls the operation of each component of the adjustment PC 1301, and under the control of the OS, communicates with the projector 1101 and transmits a predetermined command according to the operation of the adjustment person.

The ROM (Read Only Memory) 1312 stores a program or the like that is executed when the adjustment PC 1301 is started. The RAM (Random Access Memory) 1313 temporarily stores programs executed by the CPU 1311 and data used by those programs during execution.

The projector interface 1314 is an interface for connecting to the projector 1101. The adjustment PC 1301 and the projector 1101 are connected by a predetermined communication line, and the projector interface 1314 controls the exchange of data between the adjustment PC 1301 and the projector 1101.

The display controller 1315 is a dedicated controller for actually processing the drawing command issued by the CPU 1311. The drawing data processed by the display controller 1315 is once written in the graphic memory and then output to the display 1316. The display 1316 is, for example, a display device composed of an LCD (Liquid Crystal Display) or a CRT (Cathode Ray Tube).

The input device interface 1317 receives the signal input from the keyboard 1318 or the mouse 1319, and transmits a predetermined command to the CPU 1311 according to the signal pattern. The keyboard 1318 and the mouse 1319 are used, for example, when an adjusting person who adjusts the projector 1101 performs an adjustment operation on a computer.

The external storage device 1320 is, for example, a storage device such as a hard disk drive (HDD), in which the above-mentioned programs and data are recorded, and at the time of execution, the external storage device 1320 is loaded into the RAM 1313 from there as needed.

The external recording medium drive device 1321 accesses the recording surface of a portable external recording medium 1330 such as a CD (Compact Disc), MO (Magneto-Optical Disc), or DVD (Digital Versatile Disc), and is recorded there. It is a device that reads the existing data. The external recording medium 1330 can also record a program for adjusting the projection position and focus of the projector 1101 according to the present invention. The data recorded in the external recording medium 1330 is stored in the external storage device 1320 via the external recording medium driving device 1321, and if it is a program, it is loaded into the RAM 1313 at the time of execution.

Further, as another distribution mode of the program according to the present invention, it is said that the program is stored in the external storage device 1320 from a predetermined server on the network via the network and network interface (not shown) of the adjustment PC 1301. A route is also possible. The program stored in this way is loaded into the RAM 1313 at the time of execution and executed in the same manner as described above.

FIG. 44 is a diagram showing a pattern image 1421 projected from the projector 1101 on the screen 1303 of the display unit 100H. The factory adjustment person displays the pattern image 1421 by performing a predetermined operation on the adjustment PC 1301, and observes the display state from the display screen area 19 of the game machine 1. At this time, the projection position and the focus of the projector 1101 are adjusted by performing an operation of adjusting the pattern image 1421 so as to be an index projection position which is an ideal projection position.

As shown in FIG. 44, the pattern image 1421 projected from the projector 1101 is configured to include, for example, a center point 1421a, a plurality of concentric circles 1421b, a rectangle 1421c tangent to the outermost concentric circles, a horizontal line 1421d, and a vertical line 1421e. To.

The factory adjuster adjusts the projection position so that the pattern image 1421 is aligned with the index projection position 1411 (center point 1411a, horizontal line 1411b, vertical line 1411c), which is an ideal projection position. For example, in performing the center adjustment, the horizontal position (X-axis direction) and the vertical position (Y-axis direction) of the center point 1421a of the pattern image 1421 and the center point 1411a of the index projection position 1411 are adjusted to match. Further, in performing the horizontal adjustment, for example, the horizontal line 1421d of the pattern image 1421 and the horizontal line 1411b of the index projection position 1411 are compared, and the difference between the angles (indicated by reference numeral 1431 in FIG. 44) is 0 degree. Adjust so that

Further, the factory adjuster adjusts the focus so that, for example, the center point 1421a of the pattern image 1421 is in focus at the projection position on the screen 1303.

The factory adjustment person can adjust the projection position and the focus by operating the keyboard or the like of the adjustment PC 1301. For example, on the keyboard of the adjustment PC 1301, pressing the "↑" key shifts the pattern image 1421 upward by 1 pixel, and pressing the "↓" key causes the pattern image 1421 to shift downward by 1 pixel. shift. Further, by pressing the "L" key, the pattern image 1421 is rotated counterclockwise, and by pressing the "R" key, the pattern image 1421 is rotated clockwise. Further, by pressing the "F" key or the "B" key, the focus position is moved and the focus is adjusted. In this way, the factory adjustment person confirms the position of the pattern image 1421 that fluctuates due to the operation while operating the keyboard of the adjustment PC 1301, and adjusts the pattern image 1421 so that it matches the index projection position 1411.

Here, the index projection position 1411 is a virtual index that is not actually displayed, but for this adjustment, some index may be temporarily placed on the screen 1303.

In the example of FIG. 44, the pattern image 1421 is projected on the screen 1303 of the display unit 100H, but in the structure of the display unit 100H as shown in FIG. 32, the pattern image 1421 is projected on the movable screen 1304. It may be. In addition, in the above adjustment of the projector 1101, the pattern image 1421 can be projected onto screens and accessories at various positions depending on the structure of the display unit.

FIG. 45 is a flowchart illustrating the adjustment process of the projection position and the focus of the projector 1101 by the adjustment PC 1301 in a simplified manner. In FIG. 45, the processing on the left side is the processing by the adjustment PC 1301, and the processing on the right side is the processing by the projector 1101. Here, the adjustment PC 1301 and the projector 1101 are interlocked to perform the adjustment process.

After connecting the adjustment PC 1301 and the projector 1101 by a predetermined communication line, the factory adjustment person activates the projection position / focus adjustment program on the adjustment PC 1301 so that the pattern image 1421 is displayed on the projector 1101. Instruct. The projection position and focus adjustment process is started by the operation of the factory adjuster.

First, the adjustment PC 1301 receives an instruction to start the projection position adjustment process in response to the operation of the factory adjustment person described above (step S10).

When the projector 1101 receives the display instruction of the pattern image 1421 from the adjustment PC 1301 in response to the reception of the start instruction in step S10, offset data (projection position adjustment data and focus adjustment data) and initial setting data are output from the EEPROM 1104. Read (step S12). Next, the projector 1101 processes the pattern image data from the read offset data and the initial setting data (step S14), and projects the pattern image 1421 onto the screen 1303 under the control of the control LSI 1103 or the like (step S16).

When the pattern image 1421 is displayed by the projector 1101, the OK button is displayed on the adjustment screen (not shown) displayed on the display of the adjustment PC 1301 by the factory adjustment person in the adjustment PC 1301 by the projection position / focus adjustment program. It is checked whether or not the button is pressed or the offset data change instruction is operated (step S18, step S20). The projection position / focus adjustment program repeats these processes until these operations are performed. Here, the factory coordinator can cancel the process by a predetermined operation, but the determination is omitted here.

If it is determined in step S20 that the factory coordinator has given the change instruction, the projector 1101 is instructed to change the projection position or focus of the pattern image 1421 according to the change instruction (step S22). For example, when the factory adjustment person instructs the pattern image 1421 to be displaced upward by 5 pixels on the adjustment screen, the instruction is transmitted to the projector 1101.

When the projector 1101 receives the instruction in step S22, the projector 1101 reflects the displacement included in the instruction in the offset data (projection position adjustment data and focus adjustment data) read from the EEPROM 1104, and this offset data and the initial setting data The pattern image data is processed based on the above, and the pattern image 1421 is projected onto the screen 1303 under the control of the control LSI 1103 or the like (step S24). Next, it is checked whether or not the OK button is pressed or the offset data change instruction is operated again (step S18, step S20), and thereafter, the change instruction of the pattern image 1421 and the factory coordinator The operation check is repeated, and as a result, the projection position and focus of the pattern image 1421 are adjusted.

When the OK button is pressed in step S18 (for example, when the factory adjuster moves the position of the pattern image 1421 so as to match the index projection position 1411 and completes the focus adjustment), the adjustment PC 1301 moves. The projector 1101 is instructed to store the projection position adjustment data and the focus adjustment data (step S26).

Upon receiving the instruction in step S26, the projector 1101 stores the current projection position adjustment data and the focus adjustment data (that is, the data updated to a preferable value by the factory adjustment person) in the EEPROM 1104 (step S28).

Next, the function of adjusting the brightness of the LED light source of the projector 1101 in the display unit 100H according to the ninth embodiment of the gaming machine according to the present invention will be described. The projector 1101 controls the LED driver 1106 via the DLP control circuit 1105 under the control of the control LSI 1103 to operate the LED light sources (each of the R, G, and B LED light sources) of the optical unit 1108. The brightness of the LED light source is adjusted by using the communication function of the projector 1101 and the adjustment PC connected to the projector 1101. As the adjustment PC, the same one as the adjustment PC 1301 described above can be used.

The factory coordinator (or other coordinator) can perform a predetermined operation from the adjustment PC 1301 to set the brightness of the LED light source to a predetermined level. By such adjustment, when the brightness of the LED light source is set to zero or low, the projector 1101 can be put into a power saving state.

Further, in the above-mentioned brightness adjustment, the brightness level of the LED light source is directly changed by operating the adjustment PC 1301, but the predetermined condition is satisfied in the normal state where the game machine 1 is installed in the game hall. If this is the case, the adjustment PC 1301 may be set in advance so that the brightness of the LED light source becomes a predetermined level under the control of the game machine 1 (control of the sub control circuit 70). For example, in the game machine 1, when the game is not being performed in the standby state, the brightness of the LED light source can be set to zero so that the display on the demo screen or the like cannot be visually recognized. Further, in the game machine 1, when the game is not being performed in the standby state, the LED light source can be set to a brightness extremely close to zero so that the display on the demo screen or the like is almost invisible. Further, it is also possible to detect the heat of a predetermined portion of the game machine 1 (for example, inside the projector 1101) with a temperature sensor or the like, and set the brightness level of the LED light source to be changed according to the result of the heat detection. it can.

Next, in the display unit 100H according to the ninth embodiment of the gaming machine according to the present invention, adjustment of the display mode by projecting the irradiation light by the projector 1101 (projection position, focus, color tone / gradation of the irradiation light). , And the adjustment of the trapezoidal distortion) will be described with respect to the method of performing the adjustment with the game machine 1. Does the projector 1101 (see FIG. 32) supported by the ceiling plate 1300a of the display unit 100H finally meet the specifications such as the projection position and focus of the irradiation light at the timing when the installation in the amusement park is completed? A check is made to see if it is present and adjustments are made as necessary.

Here, the adjustment of the projector 1101 is performed by the sub CPU 71 activating the adjustment program by performing a predetermined operation on the game machine 1 (transition to the projection position adjustment mode). The started program is referred to as the game hall adjustment person (for convenience, to distinguish it from the factory adjustment person at the time of shipment from the factory, etc., the place of the adjustment operation is limited to the game hall. However, it operates so that the projection position, focus, color tone / gradation, and trapezoidal distortion of the projector 1101 can be adjusted.

When the person in charge of adjusting the game hall operates the adjustment screen displayed on the liquid crystal display panel 20a of the game machine 1, the projection position, focus, and color tone of the irradiation light on the projector 1101 are controlled by the sub CPU 71 of the sub control circuit 70. Adjustments are made for gradation and trapezoidal distortion. When the projector 1101 is adjusted in this way, the displacement data for adjustment is stored as offset data in, for example, the SRAM 74 of the sub-control circuit 70 (see FIG. 8).

More specifically, the offset data stored in the SRAM 74 includes center adjustment values (that is, vertical (Y-axis) displacement, horizontal (X-axis) displacement), and horizontal adjustment values (X-axis). Includes projection position adjustment data, including offset data (rotation angle to keep the) horizontal. Further, the offset data includes focus adjustment data including offset data such as displacement related to focus adjustment (for example, displacement of aperture value (F value) that defines depth of field, displacement of lens position related to focus adjustment, etc.). Is included. Further, the offset data includes color tone / gradation adjustment data including offset data such as displacement related to color tone and gradation, and trapezoidal distortion adjustment data including offset data such as displacement related to bottom adjustment for adjusting trapezoidal distortion. ..

FIG. 46 shows an outline of the processing at the time of adjusting the projector 1101. As shown in FIG. 46, the pattern image data is pre-processed by the GPU 75 under the control of the sub CPU 71, and the processed pattern image data is further processed by the control LSI 1103 of the projector 1101 and projected onto the screen 1303. To. The person in charge of adjusting the amusement park adjusts the display mode (projection position, etc.) of the pattern image according to the instruction via the touch sensor panel 20b of the liquid crystal display device 20. The offset data 1451 is changed by the adjustment by the person in charge of adjusting the game hall, and the pattern image data is processed by the GPU 75 according to the value. When the GPU 75 reads the offset data 1451 stored in the SRAM 74, it reads the offset data 1451 via the sub CPU 71. The offset data 1451 includes projection position adjustment data 1451a, focus adjustment data 1451b, color tone / gradation adjustment data 1451c, and trapezoidal distortion adjustment data 1451d.

The control LSI 1103 of the projector 1101 controls the DLP control circuit 1105 and the LED driver 1106 (see FIG. 33) on the optical unit 1108 based on the read initial setting data 1352, projection position adjustment data 1351a, and focus adjustment data 1351b. , The pattern image is projected on the screen 1303 of the game machine 1. The projection position, focus, and the like of the pattern image change according to the instruction (adjustment) via the touch sensor panel 20b, and the person in charge of adjusting the game hall makes the adjustment while looking at the projected pattern image.

By such adjustment, the final projected image can be adjusted for each game machine 1, and comprehensive adjustment can be made by combining the operation of the projector 1101 and the other components of the game machine 1. It becomes. In this adjustment, the offset data 1351 stored in the EEPROM 1104 of the projector 1101 does not change, and only the offset data 1451 stored in the SRAM 74 of the sub-control circuit 70 is updated according to the adjustment of the game hall adjuster. .. Further, here, the initial setting data 1352 is a reference value set for the operation of the projector 1101 as described above, and is stored in, for example, the EEPROM 1104.

Regarding focus adjustment, if the processing of pattern image data by GPU75 cannot correspond to the focus change specified by the person in charge of adjusting the playground, the focus adjustment data itself is transmitted to the projector 1101 to change the specified focus. It can also be configured to be realized by the projector 1101.

FIG. 47 shows an outline of the processing of the sub-control circuit 70 and the projector 1101 when the game is executed after the adjustment. As shown in FIG. 47, the effect image data is pre-processed by the GPU 75 under the control of the sub CPU 71, and the processed pattern image data is further processed by the control LSI 1103 of the projector 1101 to be processed by the game machine 1. It is projected on the screen 1303. The GPU 75 processes the effect image data provided by the sub CPU 71 based on the projection position adjustment data 1451a, the color tone / gradation adjustment data 1451c, and the like included in the offset data 1451 read from the SRAM 74 (via the sub CPU 71). To do.

The control LSI 1103 of the projector 1101 receives the effect image data processed based on the offset data 1451 stored in the SRAM 74 from the GPU 75 of the sub-control circuit 70, and stores the effect image data from the EEPROM 1104 at the time of adjustment by the factory adjuster. The projected projection position adjustment data 1351a and focus adjustment data 1351b are read, and the received effect image data is further processed based on these adjustment data and the initial setting data 1352. Then, the control LSI 1103 controls the DLP control circuit 1105 and the LED driver 1106 (see FIG. 33) to project the effect image processed in such two stages onto the optical unit 1108 (on the screen 1303 of the game machine 1). Let me.

For example, the center adjustment value (shift in the vertical direction (on the Y axis)) of the projection position adjustment data 1351a is +2 (pixels), the displacement in the vertical direction (on the Y axis) of the initialization data 1352 is 0 (pixels), and the projection is performed. When the center adjustment value (displacement in the vertical direction (on the Y axis)) of the position adjustment data 1351a is +5 (pixels), the effect image data is shifted upward by 2 pixels as a whole by the GPU 75 of the sub-control circuit 70. After that, the control LSI 1103 of the projector 1101 is processed so as to shift upward by 5 pixels as a whole, and finally, the content is shifted upward by 7 pixels as a whole from the original production image data. , Projected onto the screen 1303 by the optical unit 1108. Here, for example, the effect image data is prepared in a size larger than the size actually projected on the screen or the like (large size in both vertical and horizontal directions), and when the above-mentioned projection position adjustment is performed, the large size range is prepared. The shift process is performed within.

Further, regarding the trapezoidal distortion, the GPU 75 of the sub-control circuit 70 adjusts, for example, the reverse trapezoidal distortion to the effect image data according to the trapezoidal distortion adjustment data (for example, to adjust the lengthening of the base). If a negative value is set as the value, it is processed so that the upper side of the image data becomes longer so that it can be canceled (digital keystone correction).

Regarding the focus adjustment, if the processing of the effect image data by the GPU 75 cannot correspond to the adjustment based on the focus adjustment data 1451b, the focus adjustment data itself is transmitted to the projector 1101 to change the focus specified by the projector 1101. It can also be configured to be realized.

At the upper part of FIG. 48, a pattern image 1521 is projected from the projector 1101 on the screen 1303 of the display unit 100H, and an adjustment screen 1541 for making adjustments is displayed on the liquid crystal display panel 20a of the liquid crystal display device 20. It is shown.

The person in charge of adjusting the game hall displays the pattern image 1521 on the screen 1303 by performing a predetermined operation on the game machine 1, and observes the display state from the display screen area 19 of the game machine 1. At this time, if an operation such as adjusting the pattern image 1521 so as to be an index projection position which is an ideal projection position is performed on the adjustment screen 1541 displayed on the liquid crystal display panel 20a of the liquid crystal display device 20, the result is obtained. In conjunction with this, the projection content of the screen 1303 changes, and the projection position, focus, color tone / gradation, and trapezoidal distortion of the projector 1101 are adjusted.

As shown in FIG. 48, the pattern image 1521 projected from the projector 1101 is configured to include, for example, a center point 1521a, a plurality of concentric circles 1521b, a rectangle 1521c tangent to the outermost concentric circles, a horizontal line 1521d, and a vertical line 1521e. , Each concentric circle 1521b is displayed in a different color, and further, different colors (for example, yellow, blue, red, green) are displayed at the four corners of the rectangle 1521c.

The person in charge of adjusting the game hall adjusts the projection position so that the pattern image 1521 is aligned with the index projection position 1511 (center point 1511a, horizontal line 1511b, vertical line 1511c) which is an ideal projection position. For example, the center point 1521a of the pattern image 1521 and the center point 1511a of the index projection position 1511 are adjusted so that the horizontal position (X-axis direction) and the vertical position (Y-axis direction) match. Further, for example, the horizontal line 1521d of the pattern image 1521 and the horizontal line 1511b of the index projection position 1511 are compared, and the difference between the angles (indicated by reference numeral 1531 in FIG. 48) is adjusted to be 0 degrees.

Further, the person in charge of adjusting the playground adjusts the focus so that, for example, the center point 1521a of the pattern image 1521 is in focus at the projection position on the screen 1303. Further, the color tones and gradations of R (red), G (green), and B (blue) are adjusted by, for example, comparing each part of the color sample and the pattern image 1521.

Further, it is checked whether or not the pattern image 1521 has trapezoidal distortion, and if trapezoidal distortion occurs, for example, the trapezoidal distortion is adjusted by adjusting the length of the base.

As described above, the person in charge of adjusting the game hall operates the adjustment screen 1541 displayed on the touch sensor panel 20b of the liquid crystal display device 20 of the game machine 1, thereby projecting the projection position, focus, color tone / gradation, and trapezoidal distortion. Make adjustments for each.

At the bottom of FIG. 48, an adjustment screen 1541 displayed on the touch sensor panel 20b is illustrated. In the adjustment of the projection position, the center adjustment is performed by, for example, dragging (shifting) the center point 1542a displayed on the center adjustment unit 1542 up, down, left and right on the panel with a finger, and the center of the pattern image 1521 linked with this operation. The point 1521a is moved so as to coincide with the center point 1511a of the index projection position 1511. The center adjustment displacement display unit 1543 shows an adjustment value representing a displacement on the X-axis and an adjustment value representing a displacement on the Y-axis, and the adjustment value fluctuates following the above drag. The adjustment value is displayed, for example, in pixel units.

Further, the center adjustment displacement display unit 1543 can be directly input by touching a number with the software keyboard 1551 arranged on the right side (the input of other adjustment values can be directly input in the same manner. is there).

In the adjustment of the projection position, the horizontal adjustment adjusts the inclination of the X-axis of the pattern image 1521 by, for example, dragging (shifting) the slide bar displayed on the horizontal adjustment unit 1544 left and right on the panel with a finger (shifting). The horizontal line 1521d of the pattern image 1521 is moved so as to coincide with the horizontal line 1511b of the index projection position 1511). The adjustment value is, for example, -127 to +127 (here, 1 = 0.25 °). This adjustment value can be directly input with the above-mentioned software keyboard 1551, and further, the adjustment value can be changed by tapping the "+" display area or the "-" display area displayed on the horizontal adjustment unit 1544. Can be (larger or smaller).

Further, in the center adjusting unit 1542, the angle of the pattern image 1521 may be adjusted by using two fingers, fixing one finger, and dragging the other finger.

To adjust the focus, for example, the slide bar displayed on the focus adjustment unit 1545 is dragged (shifted) left and right on the panel by a finger to adjust the focus of the pattern image 1521 (the center point 1521a of the pattern image 1521 is set). , Adjust so that the screen 1303 is in focus). The focus adjustment unit 1545 shows an adjustment value indicating an F value or a displacement of the lens moving distance. This adjustment value can be directly input with the above-mentioned software keyboard 1551, and further, the adjustment value can be changed by tapping the "+" display area or the "-" display area displayed on the focus adjustment unit 1545. Can be (larger or smaller).

In adjusting the color tone / gradation, for adjusting R (red), for example, drag (shift) the slide bar displayed in the R color tone adjustment unit of the color tone / gradation adjustment unit 1546 to the left or right on the panel with a finger. ), Adjust the color tone of "red" in the pattern image 1521. The adjustment value is the value of the displacement with respect to R, and is, for example, −10 to +10. This adjustment value can be directly input with the above-mentioned software keyboard 1551, and further, a "+" display area or a "-" display area displayed in the R color tone adjustment section of the color tone / gradation adjustment section 1546. You can change the adjustment value (larger or smaller) by tapping. Similarly, in the G color tone adjustment unit, the B color tone adjustment unit, and the gradation adjustment unit of the color tone / gradation adjustment unit 1546, the corresponding adjustment values are set by the person in charge of adjusting the game hall.

To adjust the trapezoidal distortion, for example, the slide bar displayed on the trapezoidal distortion adjusting unit 1547 is dragged (shifted) left and right on the panel by a finger to adjust the length of the base of the rectangle of the pattern image 1521. The adjustment value represents the displacement of the length of the base, and is, for example, -20 to +20. This adjustment value can be directly input with the above-mentioned software keyboard 1551, and further, the adjustment value can be changed by tapping the "+" display area or the "-" display area displayed on the horizontal adjustment unit 1544. Can be (larger or smaller).

When the person in charge of adjusting the game hall presses the OK button 1548 when all the adjustments are completed, the adjustment process of the projector 1101 in the game machine 1 is completed, and the game machine 1 is in the initial state (for example, the state in which the game screen is displayed). ) Return.

FIG. 49 is a flowchart illustrating the projection position and focus adjustment processing of the projector 1101 by the game machine 1 in a simplified manner. In FIG. 49, the processing on the left side is the processing by the sub-control circuit 70 of the game machine 1, and the processing on the right side is the processing by the projector 1101. Here, the sub-control circuit 70 and the projector 1101 interlock to perform the adjustment process.

The game hall adjustment person performs a predetermined operation on the game machine 1, shifts the game machine 1 to the projection position adjustment mode, and then starts the adjustment process of the projection position etc. by the operation of the game hall adjustment person. Will be done.

First, the sub-control circuit 70 receives an instruction to start the projection position adjustment process in response to the operation of the above-mentioned game hall adjustment person (step S40).

Next, offset data (projection position adjustment data, focus adjustment data, color tone / gradation adjustment data, trapezoidal distortion adjustment data) is read from SRAM 74 of the sub-control circuit 70 (step S42), and then converted into offset data by GPU75. Based on this, the pattern image data is processed, and the processed pattern image data is transmitted to the projector 1101 (step S44).

Upon receiving the pattern image data transmitted in step S44, the projector 1101 reads offset data (projection position adjustment data and focus adjustment data) and initial setting data from the EEPROM 1104 (step S46). Next, the projector 1101 further processes the received pattern image data from the read offset data and the initial setting data (step S48), and projects the pattern image 1521 onto the screen 1303 under the control of the control LSI 1103 or the like (step S48). S50).

When the pattern image 1521 was displayed by the projector 1101, the person in charge of adjusting the game hall pressed the OK button or operated the instruction to change the offset data on the adjustment screen 1541 displayed on the liquid crystal display device 20 of the game machine 1. It is checked whether or not (step S52, step S54). These processes are repeated until these operations are performed. Here, the person in charge of adjusting the game hall can cancel the process by a predetermined operation, but the determination is omitted here.

When it is determined in step S54 that the person in charge of adjusting the game hall has given the change instruction, the pattern image data is processed based on the change instruction, and the processed pattern image data is transmitted to the projector 1101 (step S56). .. For example, when the person in charge of adjusting the game hall instructs the adjustment screen 1541 to displace the pattern image 1521 upward by 5 pixels, the pattern image data is generated so that the entire pattern image 1521 moves upward by 5 pixels. It will be processed.

Here, the projector 1101 proceeds to the process of step S48, further adds the offset data and the initial setting data read in step S46, processes the received pattern image data (step S48), and is controlled by the control LSI 1103 or the like. The pattern image 1521 is projected on the screen 1303 (step S50).

After that, it is checked whether or not the OK button is pressed or the offset data change instruction is operated (step S52, step S54), and thereafter, the change instruction of the pattern image 1521 and the person in charge of adjusting the playground The operation check is repeated, and as a result, the projection position and the like of the pattern image 1521 are adjusted.

When the OK button is pressed in step S52 (for example, when the person in charge of adjusting the game hall moves the position of the pattern image 1521 so as to match the index projection position 1511, and completes focus adjustment, trapezoidal distortion adjustment, and the like. ), The offset data stored in the SRAM 74 is updated by reflecting the changed contents (that is, reflecting a value preferable by the game hall coordinator) (step S58).

Next, the heat countermeasure structure of the projector 1101 will be described in the display unit 100H according to the ninth embodiment of the present invention. Although the mounting method for the display unit 100H will be described here, the same heat countermeasure structure can be adopted when the projector 1101 is mounted for the display units 100 to 100G described above. Further, the same structure can be used for other projectors.
