In addition, the main control board 64 performs control according to each state of the key.

  Next, the main part of the present invention will be described.

  As shown in FIGS. 5 and 6, a light emitting unit 112 that emits laser light is provided at the upper end of the back wall 12 </ b> B (back plate) of the box 12. The light emitting unit 112 has a plurality of light emitting units arranged in a line in the left-right direction from the left end to the right end of the back wall 12B (light emitting unit A, light emitting unit B, light emitting unit C in FIG. 6). ...). A light receiving portion 114 that receives laser light from the light emitting portion 112 is provided at the lower end of the back wall 12B of the box 12. In the same manner as the light emitting unit 112, the light receiving unit 114 has a plurality of light emitting units arranged in a line in the left-right direction from the left end to the right end of the back wall 12B (the light receiving unit A ′ in FIG. 6). , Light receiving part B ′, light receiving part C ′,...

  Here, each light emitting unit 112 and each light receiving unit 114 correspond to each other, and the laser light emitted from one light emitting unit 112 is received by the light receiving unit 114 positioned (opposite) directly below the light emitting unit 112. It is configured to be. That is, in the light emitting unit 112 of FIG. 6, “light emitting unit A” corresponds to “light receiving unit A ′”, “light emitting unit B” corresponds to “light receiving unit B ′”, and “light emitting unit C” is , Corresponding to “light receiving part C ′” (the same applies to the light emitting part C). Therefore, there are as many light receiving units 114 corresponding to the light emitting units 112 as the number of the light emitting units 112, and the laser beams emitted from the respective light emitting units 112 are received by the corresponding light receiving units 114.

  As a modification thereof, a light emitting portion and a light receiving portion may be provided also on the left end and the right end of the back wall 12B of the box 12. That is, as shown in FIGS. 7 and 8, a light emitting unit 116 that emits laser light is provided at the left end of the back wall 12 </ b> B of the box 12. In the light-emitting portion 116, a plurality of light-emitting portions are arranged from the upper end to the lower end of the back wall 12B along the vertical direction. A light receiving unit 118 that receives laser light from the light emitting unit 116 is provided at the right end of the back wall 12B of the box 12. In the light receiving unit 118, in the same manner as the light emitting unit 116, a plurality of light emitting units are arranged in the vertical direction from the upper end to the lower end of the back wall 12B.

  Here, each light emitting unit 116 and each light receiving unit 118 correspond to each other, and the laser light emitted from one light emitting unit 116 is received by the light receiving unit 118 positioned (opposite) next to the light emitting unit 116. It is configured to be. Therefore, there are as many light receiving units 118 corresponding to the light emitting units 116 as the number of the light emitting units 116, and the laser beams emitted from the respective light emitting units 116 are received by the corresponding light receiving units 118.

  Each of the light emitting units 112 and 116 is electrically connected to the main control board 64, and the light emission control is executed by the main control board 64. The light emitting units 112 and 116 are individually controlled to emit light by the main control board 64. The light receiving units 114 and 118 are electrically connected to the main control board 64, and the light reception results in the light receiving units 114 and 118 are output to the main control board 64 as detection signals related to the detection results. Based on the detection signals from the light receiving units 114 and 118, the main control board 64 specifies whether or not there is an unauthorized circuit board, an opening, or a foreign object that causes the back wall 12B of the box 12 to execute unauthorized games. To do.

  As shown in FIGS. 6 and 8, the rear wall 12B of the box 12 has a ventilation hole 122 for lowering the temperature inside the box 12 and a sensor wire extraction hole for taking out a sensor wire for automatic replenishment. 124, a rear speaker hole 126 for outputting the sound of the rear speaker, a computer line extraction hole 128 for taking out an external computer line, a power cord connection hole 130 for connecting a power cord, and a medal supply A game medal replenishment hole 132 is formed for removing and connecting the cover when the mouth is connected. Thus, since only the hole is formed in the back wall 12B of the box 12 and no protruding appendage is formed, the laser beam is not emitted in a normal state (the state in which there is no illegal accessory). There is nothing to block, and the laser beams emitted from the light emitting units 112 and 116 are received by the light receiving units 114 and 118, respectively.

  Next, the electrical configuration of the gaming machine 10 will be described.

  As shown in FIGS. 9 and 10, in the gaming machine 10, the sub-control board 52, the door board 56, the rotating board 68, the power board (power supply means) 76, etc. center the data on the main control board 64. It is connected and configured to be able to communicate.

  The main control board 64 is a board that manages the progress and production of the entire game performed in the gaming machine 10. On the main control board 64, a CPU, a ROM, a RAM and the like are mounted so as to be able to exchange data with each other via a bus. The main control board 64 receives a signal indicating that the start lever 38 has been operated from the door board 56 mounted on the front door 14, and executes the game control process, while the sub control board 52, the door board 56, The operation of each substrate is controlled by outputting a control command (or control signal) toward the rotating substrate 68 or the like.

  As shown in FIG. 10, the main control board 64 includes a game control means (for example, CPU) 64A, a game progress stop means (for example, CPU) 64B, a storage means (for example, ROM, RAM) 64C, and fraud determination. Means (for example, CPU) 64D, light emission control means (for example, CPU detection area changing means) 64E, and fraud detection processing execution means 64F for executing fraud detection processing for detecting the state of the outer surface of the box. ing.

  The game control means 64A controls the progress of the game executed in the slot machine 10. The game progress stopping means 64B stops the progress of the game by the game control means 64A when the fraud of the back wall 12B of the box 12 is detected.

  The storage unit 64C stores the normal state of the back wall 12B of the box 12. Specifically, the relationship between the light receiving pattern and the normal state when the laser beams emitted from the light emitting units 112 and 116 are received by the light receiving units 114 and 118 is stored. For example, if there are no non-illegal accessories that block the laser beam on the back wall 12B of the box body 12, when the laser beam is emitted from all the light emitting units 112 and 116, the laser beam is emitted from all the light receiving units 114 and 118. Light is received. This is one light receiving pattern indicating a normal state. Further, when there are accessories (for example, an automatic medal replenisher connected to the game medal replenishment hole 132) that are not illegal in the specific area of the back wall 12B of the box 12, these The laser light blocked by the accessory cannot be received by the light receiving portions 114 and 118. The light receiving patterns at the light receiving portions 114 and 118 that show this variation also become one light receiving pattern that shows a normal state. As described above, assuming that the storage unit 64C has an accessory or the like that is not illegal in any of the entire regions of the back wall 12B of the box 12 and the light receiving unit 114. 118, the relationship with the light reception pattern is recognized in advance through experiments, and the content obtained thereby is stored as a light reception pattern indicating a normal state. Accordingly, by storing all the light receiving patterns of the laser light received by the light receiving units 114 and 118, it is possible to easily and reliably determine whether or not the fraud determination unit 64D is in a normal state. The storage unit 64C stores a program related to the light emission patterns of the light emitting units 112 and 116 whose light emission is controlled by the light emission control unit 64E.

  For example, as shown in FIGS. 6 and 8, the back wall 12 </ b> B of the box 12 has a plurality of holes in a normal state, but is not provided with an appendage that protrudes greatly. For this reason, the laser beams emitted from the light emitting units 112 and 116 are received by the corresponding light receiving units 114 and 118, and the light receiving pattern in which the light is received by all the light receiving units 114 and 118 is in a normal state. Is stored in the storage means 64C.

  As shown in FIG. 10, the fraud determination unit 64D determines whether or not the current state of the back wall 12B of the box 12 matches the normal state stored in the storage unit 64C. Specifically, the fraud determination unit 64D compares the light reception pattern actually received by the light receiving units 114 and 118 with the light reception pattern in the normal state stored in the storage unit 64C, and confirms that they match. Judge whether or not.

  For example, as shown in FIGS. 6 and 8, when the laser light emitted from each light emitting unit 112, 116 is received by each light receiving unit 112, 116 facing each light emitting unit 112, 116, the box 12 The state of the rear wall 12B coincides with the light receiving pattern stored in the storage unit 64C, and the fraud determination unit 64D determines that the back wall 12B of the box 12 is not fraudulent. On the other hand, if the laser beam is not received by some of the light receiving units 114 and 118, an obstacle that is an unauthorized object is present, and the state of the back wall 12B of the box 12 is stored in the storage unit 64C. The fraud determination means 64D determines that the back wall 12B of the box 12 is fraudulent without being matched with the received light pattern.

  As shown in FIG. 10, the light emission control means 64E individually controls the emission of the laser light from each of the light emitting units 112 and 116 based on the program related to the light emission pattern stored in the storage means 64C. Specifically, when there is an accessory that is not a fraudulent object on the back wall 12B of the box body 12, the laser light in that area is not received by the light receiving units 114 and 118, so the light emission control means 64E It is possible to individually control so that the emission of the laser light from the light emitting units 112 and 116 is stopped and the laser light is emitted from the other light emitting units 112 and 116. As described above, when there is an accessory that is not an improper object on the back wall 12B of the box body 12, the light emitting units 112 and 116 are controlled so as to avoid the area, thereby receiving light in the storage unit 64C. It is not necessary to store all the light receiving patterns of the laser beams received by the units 114 and 118. That is, by taking into account the position of an accessory that is not a fraudulent object and controlling the light emission on the light emitting units 112 and 116 individually, all the light receiving units 114 and 118 as light receiving patterns to be stored in the storage unit 64C. Since only the light receiving pattern is required when light is received, the capacity of the storage unit 64C can be reduced, and the work of storing the light receiving pattern in the storage unit 64C can be reduced.

  Here, in order to change the setting of the light emission pattern of the light emitting units 112 and 116 and the light receiving pattern of the light receiving units 114 and 118, the keys in the setting key 110 are set to the first ON state, whereby the light emitting units 112, The setting of the light emission pattern 116 and the light reception patterns of the light receiving portions 114 and 118 can be easily changed. Specifically, the light receiving pattern stored in the storage unit 64C can be rewritten by setting the key in the setting key 110 to the first ON state, and the light emission control stored in the storage unit 64C. The program content relating to the light emission control of the means 64E can be changed.

  The fraud detection processing execution means 64F executes fraud detection processing for detecting fraud on the outer surface of the box 12. When executing the fraud detection process, the fraud detection process execution unit 64F outputs a control signal for prompting the light emission control unit 64E to emit light.

  As shown in FIG. 9, the sub control board 52 is mounted with a CPU, a ROM, a RAM, and the like connected to each other via a bus so that data can be exchanged in the same manner as the main control board 64. In addition, various lamps 26, various speakers 24 and 72, an effect display device 22, a rotating backlight 102, and the like are connected to the sub control board 52. Here, the spinning cylinder backlight 102 is a light that is provided in each of the spinning cylinders 30A, 30B, and 30C and illuminates the pattern drawn on the surface of the spinning cylinders 30A, 30B, and 30C from the back side. The sub control board 52 analyzes the control command received from the main control board 64 and outputs drive signals to the various lamps 26, the various speakers 24 and 72, the effect display device 22, and the rotary backlight 102, respectively. Thus, various effects using these are performed.

  Further, the door substrate 56 is rotated by a medal selector 58, various insertion buttons 36 and 37 for inserting stored game medals, a start lever 38 for starting rotation of the spinning cylinders 30A, 30B, and 30C. The spinning cylinder stop buttons 40A, 40B, 40C for stopping the spinning cylinders 30A, 30B, 30C, the settlement button 42 for paying out the stored game medals and the inserted game medals, and the game Various display panels 32 and the like are connected to display the state. The door board 56 is connected to the main control board 64 so as to exchange data. Therefore, when the start lever 38, the rotation stop buttons 40A, 40B, 40C, the various input buttons 36, 37, the adjustment button 42, etc. provided on the front door 14 are operated, the signal is transmitted via the door substrate 56. The main control board 64 can be supplied. The output of the medal sensor provided in the medal selector 58 is also supplied to the main control board 64 via the door board 56.

  On the rotating board 68, the rotating motors 104A, 104B, and 104C for rotating the three rotating cylinders 30A, 30B, and 30C, and the rotations for detecting the rotational positions of the rotating cylinders 30A, 30B, and 30C, respectively. Body sensors 106A, 106B, and 106C are provided. The rotating board 68 is driven by the rotating motors 104A, 104B, and 104C while detecting the rotational positions of the rotating cylinders 30A, 30B, and 30C by the rotating sensors 106A, 106B, and 106C. , 30B, 30C can be stopped at a desired rotational position. In the gaming machine 10 of this embodiment, so-called stepping motors are used for the spinning motors 104A, 104B, and 104C.

  The medal payout device 74 is connected to the main control board 64 via the relay board 75 and performs an operation of paying out a predetermined number of game medals based on a control signal from the main control board 64. The medal payout device 74 is provided with a payout sensor (not shown) in order to detect that a game medal has been paid out. When a game medal is paid out, it is detected by a payout sensor, and a signal is output to the main control board 64.

An AC voltage of 100 V is supplied to the power supply board 76, and this electric power is converted into a specified voltage and then supplied to each control board and board. In FIG. 6, a state in which power is supplied from the power supply board 76 is represented by a dashed arrow.

Next, the power-on process in the main control board 64 will be described.
The power-on process is a control process started by the main control board 64 when the power switch 80 is turned on. In the present embodiment, a fraud detection process for detecting whether or not the back wall 12B of the box 12 is fraudulent is included in one step in the power-on process.

  As shown in FIG. 11, in the power-on process, each initial setting is executed (S100). As initial settings, initial settings S100A, interrupt vector settings S100B, initial output settings S100C, IY register settings S100D of the CPUs of the main control board 64 and the sub control board 52, and status saving settings S100E of the stop / automatic settlement switch , RWM unused area clear processing S100F, etc. are executed.

  Next, the back surface check process of the back wall 12B of the box 12 is executed (S110). Details of this processing will be described later.

  After the back surface check process, the main control board 64 determines whether or not the setting key is in the first ON state (S120). That is, according to this process, if the setting key is in the first ON state, the setting change process is started.

  If it is determined that the setting key is in the first ON state (S120: YES), a setting change process is started (S130). In the setting change processing S130, light emission / reset such as resetting of the start address of the RWM clear area before setting change S130A, RWM area clearing processing S130B, the light emission pattern of the light emitting units 112 and 116, or the content of the light receiving pattern stored in the storage means 64C, etc. The received light pattern changing process 130C is executed.

  In the light emission / light reception pattern changing process S130C, an operator (such as a staff member of a hall in which the slot machine is placed) is an unobtrusive obstacle or accessory provided on the outer surface of the rear wall 12B of the box body 12 of the slot machine 10. The setting contents of the light emission patterns of the light emitting units 112 and 116 or the setting contents of the light receiving patterns of the light receiving units 114 and 118 stored in the storage unit 64C are appropriately set. For example, as shown in FIG. 6 and FIG. 8, when there are no obstacles or unauthorized objects protruding from the rear wall 12B of the box 12 in the initial state of the slot machine 10, The light emission pattern can be set such that laser light is emitted from the light emitting units 112 and 116. In addition, a light receiving pattern in which laser light is received by all the light receiving units 114 and 118 can be set as a light receiving pattern in a normal state.

  On the other hand, if there are obstacles or unauthorized objects that are not unauthorized and protrude from the rear wall 12B of the box 12 in the initial state of the slot machine 10, laser light that is blocked by the obstacles or accessories is emitted. It is possible to set a light emission pattern such that light emission of the emitted light emitting units 112 and 116 is stopped and light is emitted from the other light emitting units 112 and 116. In addition, the light receiving patterns of the light receiving units 114 and 118 that cannot receive the laser beam by being blocked by an obstacle or an accessory and the light receiving units 114 and 118 that can receive the laser beam without being blocked by the obstacle or an accessory are normal. It can be set as a light reception pattern of a state.

  After that, the RWM area clear process after the setting change, the set value, the stop / automatic settlement mode storage process, and the new game start command set are executed, and the power management code transmission process is executed.

  When it is determined that the setting key is not in the first ON state (S120: NO), the main control board 64 determines whether or not the backup check data before power-off is normal (S140). .

  As a result, when it is determined that the backup check data before power-off is normal (S140: YES), a game return process is executed by the main control board 64 (S150).

  When it is determined that the backup check data before power-off is not normal (S140: NO), backup abnormality processing is executed (S160). In the backup abnormality process S160, the RWM clear area head address reset S160A at the time of backup error, the RWM area clear process S160B, the power-on backup error code set S160C, the power management code transmission process S160D, and the RWM error code set S160E are executed. Error processing is executed (S170).

Next, the back surface check process in the main control board 64 will be described.
This back surface check process is executed by the main control board 64 as one step of the power-on process. This back surface check process is a process executed when the power is turned on with the setting key being in the second ON position.

  As shown in FIG. 12, in the back surface check process, the main control board 64 determines whether or not the normal state setting mode is set (S200). In this step, determination is made by the main control board 64 based on whether or not the setting key is in the first ON position. For example, when the power switch 80 is turned on while the setting key is in the second ON position, and then the setting key is in the first ON position, it is determined that the normal state setting mode is set.

  If it is determined that the normal state setting mode is set (S200: YES), the program for realizing the light emission pattern of the light emitting units 112 and 116 stored in the storage unit 64C and the normal state in the light receiving units 114 and 118 are displayed. Data such as the received light pattern is cleared (S210).

  Next, a fraud detection area is set (S220). This fraud detection area can be selected by operating the rotation stop buttons 40A, 40B, 40C from the changeable range of the fraud detection area stored in advance in the storage means 64C, and operating the start lever 38. By doing so, the selected fraud detection area is confirmed. Examples As the fraud detection area stored in advance, there are, for example, areas in which the light emitting part and the light receiving part that pass over the game medal supply hole 132 are excluded from the detection area. The range of the fraud detection area is displayed on the effect display device 22, and the operator performs a change operation while viewing the display. In addition to the method of selecting the fraud detection area from a predetermined detection area as described above, the administrator himself / herself looks at the situation of the outer surface of the back wall 12B of the box body 12 to determine the plurality of light emitting units 112. , 116 may be set / changed individually for the light emitting section of the area to be detected.

  Next, the initial setting fraud detection process is started (S230). In the initial setting fraud detection process, laser light is emitted from the light emitting units 112 and 116 in the fraud detection region set in S220 and received by the light receiving units 114 and 118. Thus, the light emitting units 112 and 116 that should emit laser light are specified, and the light emission pattern of the laser light emitted from each light emitting unit 112 and 116 is set / changed.

  Then, the detection result in S230 is stored in the storage means 64C (S240). That is, the light receiving pattern when the laser light is received by each of the light receiving portions 114 and 118 is stored in the storage unit 64C as a light receiving pattern indicating a normal state. Further, the set / changed light emission pattern of the laser light is stored in the storage unit 64C as the light emission pattern in the normal state.

  Furthermore, the number of times the normal state is set / changed is stored in the storage unit 64C as being +1 (S250). When the slot machine 10 is shipped to the hall, the number of times the normal state is set / changed is stored as zero (0), and this zero (0) cannot be erased from the storage unit 64C. Thereby, by displaying the number of changes different from the number known by the administrator, it is possible to easily recognize whether or not the normal state has been set illegally. Thereafter, until the power is turned on again, the game of the slot machine 10 is stopped in a stopped state, and the process does not shift to the game return process.

  On the other hand, if it is determined that it is not the normal state setting mode (S200: NO), the main control board 64 outputs a signal for executing the display of the number of setting changes on the effect display device 22 to the sub control board 52 ( S260). Thereby, the number of setting changes is displayed on the effect display device 22.

  Next, the fraud detection process of the outer surface of the back wall 12B of the box 12 is started (S270). In this process, laser light is emitted from the light emitting units 112 and 116 based on the program and the light emission pattern stored in the storage unit 64C and received by the light receiving units 114 and 118.

  Next, the light receiving pattern of the laser beam received by each of the light receiving units 114 and 118 is stored in the storage unit 64C as a detection result (S280). Thus, when the fraud detection process is executed, the light reception patterns in the light receiving units 114 and 118 are stored as the detection results in the storage unit 64C each time.

  Next, the light reception pattern in the normal state is read from the storage unit 64C (S290), and the main control board 64 determines whether or not the detection result of the fraud detection process is in the normal state (S300). In this determination process, as described above, the detection result of the fraud detection process uses the light reception patterns of the light receiving units 114 and 118 stored in the storage unit 64C, and the light reception stored in the storage unit 64C as a normal state. A pattern is used, and it is determined whether or not the two match (S310).

  Next, when it is determined that the detection result of the fraud detection process is in a normal state (S310: YES), a circuit board or the like that is an unauthorized object is not crafted on the back wall 12B of the box 12 and is in a normal state. As a result, the detection result of the fraud detection process in S270 is deleted from the storage unit 64C (S320). Thereafter, the process proceeds to a setting key confirmation process (S330).

  On the other hand, if it is determined that the detection result of the fraud detection process is not normal (S310: NO), the effect display device 22 is display-controlled from the main control board 64 via the sub control board 52, and the effect display device 22 is displayed. An error display is output (S340). Thereby, an operator or the like can visually confirm from the front of the slot machine 10 that an illegal act is being performed on the outer surface of the back wall 12B of the box 12.

  Here, if it is determined that the detection result of the fraud detection process is not normal (S310: NO), the progress of the game by the game control means 64A is stopped by the game progress stop means 64B. Specifically, a game medal inserted into the game medal slot 34 is invalidated (prohibition of medal insertion is prohibited) or the operation of the start lever 38 is invalidated. As a result, when the fraud detection process is executed when the power is turned on, the slot game is not started.

  Then, it is determined by the main control board 64 whether or not an error based on fraud has been canceled (S350). If the error is canceled (S350: YES), the process proceeds to S320. In addition, as a method of canceling | removing an error, operation of the error cancellation | release button (not shown) provided inside the front door 14 (box interior side) is mentioned. Further, the error may not be canceled unless the power is turned on again.

  As described above, according to the slot machine 10 of the first embodiment, the fraud detection process is performed on the outer surface of the back wall 12B of the box 12 when the power is turned on, and if there is a fraud, the slot game is started. Therefore, it is possible to prevent an unfair game from progressing.

  In particular, fraud can be easily and reliably detected by detecting the presence or absence of fraud with an optical sensor. For example, when a laser beam is emitted in the vertical direction of the back wall 12B by the light emitting units 112 and 116 and the light receiving units 114 and 118 provided in pairs at the upper end and the lower end of the back wall 12B of the box body 12, There is a case in which no obstacle is provided on the outer surface of the back wall 12B, and the laser beam is blocked by this obstacle and cannot be received by the light receiving units 114 and 118. At this time, the light emitting portions 112 and 116 and the light receiving portions 114 and 118 provided in pairs at the left end portion and the right end portion of the rear wall 12B of the box body 12 emit and receive the laser beam, thereby obstructing the obstacle. Thus, it is possible to detect a fraudulent circuit board or the like that is a fraudulent object in a portion where the laser beam is blocked and does not reach. That is, two fraud detection processes are performed on the outer surface of the back wall 12B of the box body 12; a fraud detection process performed by emitting laser light in the vertical direction and a fraud detection process performed by emitting laser light in the horizontal direction. Thus, since the fraud detection process can be performed effectively, it is possible to reduce the adverse effects of obstacles that are not illegal.

  For example, as shown in the modification of FIG. 13, light in which a reflecting mirror 142 is attached in advance to an obstacle (attachment) 140 that protrudes from a back wall 12B that is not a fraudulent object, and a light emitting unit and a light receiving unit are integrally combined. Whether or not there is an unauthorized object such as an unauthorized circuit board on the optical path from the optical sensor 144 to the obstacle 140 by irradiating the reflecting mirror 142 with laser light using the sensor 144 and receiving the reflected light. May be detected. That is, if there are a plurality of obstacles 140 on the outer surface of the back wall 12B of the box 12, the light emitting portions 112 and 116 and the light receiving portions 114 and 118 shown in FIG. If there is an unauthorized object 146, the laser beam that runs in the vertical direction or the laser beam that runs in the left-right direction cannot be irradiated, and the presence of the unauthorized object 146 cannot be detected. On the other hand, as shown in FIG. 13, a reflecting mirror 142 is previously attached to an obstacle (accessory) 140 that is not a fraudulent object, and an optical sensor 144 in which a light emitting unit and a light receiving unit are combined together is used. By emitting laser light from the light emitting unit, in a normal state, the laser light is reflected by the reflecting mirror 142 and returned to be received by the light receiving unit. However, if there is an unauthorized object 146 on the optical path, the laser beam is blocked by the unauthorized object 140 and is not reflected by the reflecting mirror 142. For this reason, the laser beam cannot be received by the light receiving unit, and it can be easily determined that the illegal object 146 exists. It is to be noted that one of the light emitting part or the light receiving part is attached to the obstacle (accessory) 140 that is not an improper object, instead of the reflecting mirror 142, and the other of the light emitting part or the light receiving part provided on the rear wall 12B of the box 12 is provided. The presence or absence of unauthorized objects may be determined by emitting and receiving laser light.

  Furthermore, when performing the fraud detection process for only a specific portion of the outer surface of the back wall 12B of the box 12, it is possible to control the laser light to be emitted from the specific light emitting units 112 and 116. As described above, since the fraud detection area on the outer surface of the back wall 12B of the box 12 can be freely changed, fraud matching the environment (facility environment, presence / absence of accessories, etc.) of the rear wall 12B of the box 12 is possible. Detection processing can be executed.

  In the first embodiment, the processing shown in FIGS. 11 and 12 has been described with respect to the configuration executed by the main control board 64. However, the present invention is not limited to this configuration, and control signals from the main control board 64 are used. It may be executed by the sub-control board 52 that has received this. At this time, the light emission control of each light emitting unit 112, 116 is executed by the sub control board 52, and the light reception result by each light receiving part 114, 118 is output to the sub control board 52.

  Next, a slot machine according to the second embodiment will be described with reference to the drawings. In the second embodiment, the contents and method of fraud detection processing are changed as compared with the first embodiment. For this reason, in the following description, the description of the structure which overlaps with the structure of 1st Embodiment is abbreviate | omitted, and the content and method of the fraud detection process which are the characteristics of 2nd Embodiment are demonstrated in detail.

  As shown in FIGS. 14 to 17, two rail members 152 extending in the vertical direction are provided on the outer surface of the rear wall 12 </ b> B of the box 12 of the slot machine 150 at a predetermined interval. A scanner device 154 is movably provided on each rail member 152. The scanner device 154 includes a box-shaped scanner device main body 156, a plurality of movable pieces 158 provided on the scanner device main body 156, and a contact switch 160 that is in contact with one end portion of the movable piece 158 and enables energization. I have. Further, the scanner device 154 may be configured to be movable on each rail member 152 by energizing each rail member 152, and each rail member using mechanical means such as an arm mechanism or a link mechanism. You may comprise so that it can move on 152. The scanner device 154 is electrically connected to the main control board 64 or the sub control board 52, and the driving of the scanner device 154 is controlled by the main control board 64 or the sub control board 52.

  A rotation shaft 162 is attached to the scanner device main body 156 across the width direction of the scanner device main body 156. The rotary shaft 162 is attached so that a portion in the vicinity of one end of the plurality of movable pieces 158 can rotate with respect to the rotary shaft 162. As a result, a plurality of movable pieces 158 are attached to the scanner apparatus main body 156 in a line-up in the left-right direction. Each movable piece 158 is individually rotatable with respect to the rotation shaft 162. A terminal portion 164 that can be electrically connected to the contact switch 160 is provided at one end of each movable piece 158. Further, a weight portion is provided at one end of each movable piece 158, and each movable piece 158 rotates around the rotation axis 162 by shifting the center of gravity of each movable piece 158 from the center. It is set to be easy.

  Further, a contact switch 160 is attached inside the scanner apparatus main body 156 over the width direction of the scanner apparatus main body 156. As shown in FIGS. 16 and 17, when each movable piece 158 is rotated 90 degrees around the rotation axis from the initial state, the terminal portion 164 provided at one end of each movable piece 158 is connected to the contact switch 160. It will be in an energized state by touching. Since the contact switch 160 is electrically connected to the main control board 64 or the sub control board 52, when the terminal unit 164 and the contact switch 160 are energized, an energization signal is sent from the contact switch 160 to the main control board 64 or It is output to the sub control board 52. Thereby, the main control board 64 or the sub control board 52 determines whether or not the terminal portion 164 and the contact switch 160 are in the energized state.

  Here, if the back wall 12B of the box body 12 of the slot machine 150 includes a hole 122 or the like that is not an unauthorized hole shown in FIG. 8 or an unauthorized hole 170 shown in FIG. 16, the hole 122 ( 170) Since the movable piece 158 located on the upper side loses the reaction force from the back wall 12B and the center of gravity moves due to the action of the weight portion, the movable piece 158 falls into the hole 122 (170). Rotate. When the movable piece 158 rotates about the rotation shaft 162, the terminal portion 164 of the movable piece 158 and the contact switch 160 are energized, and a certain hole 122 (170) is formed in the back wall 12B. 64 or sub-control board 52.

  Next, fraud detection processing by the slot machine 150 of the second embodiment will be described. In addition, description is abbreviate | omitted about the process which overlaps with the process of the fraud detection process by the slot machine 10 of 1st Embodiment.

  In the initial setting fraud detection process of S230 shown in FIG. 12, the scanner device 154 moves on the rail member 152, and the state of the hole formed in the back wall 12B of the box 12 is specified. Specifically, when the scanner device 154 moves and the movable piece 158 is positioned on the hole 122, the movable piece 158 rotates and the terminal portion 164 of the movable piece 158 and the contact switch 160 come into contact as described above. Power on. Accordingly, by storing the position of the scanner device 154 and the presence / absence of the energized state in association with each other, it is possible to specify in which part a regular (not illegal) hole is formed. And this state is memorize | stored in the memory | storage means 64C as a normal state.

  In the fraud detection process of S270 shown in FIG. 12, as shown in FIG. 16, the scanner device 154 moves on the rail member 152, and the fraudulent holes 170 formed on the outer surface of the rear wall 12B of the box 12 are illegally formed. To detect. When the scanner device 154 moves and the movable piece 158 is positioned on the illegal hole 170, as described above, the movable piece 158 rotates and the terminal portion 164 of the movable piece 158 and the contact switch 160 come into contact with each other to be in an energized state. Become. As a result at this time, the correspondence between the position of the scanner device 154 and the presence or absence of the energized state is stored in the storage unit 64C.

  Subsequently, in the processing step of S310 shown in FIG. 12, the detection result by the scanner device 154 in the normal state and the detection result by the scanner device 154 executed in the fraud detection process are compared and determined. As a result, if they do not match (S310: NO), it is determined that there is fraud, and the process proceeds to S340.

  As described above, according to the slot machine of the second embodiment, by moving the scanner device 154 on the outer surface of the back wall 12B of the box 12, it is possible to easily detect the presence or absence of unauthorized holes.

  Here, the configuration in which the scanner device 154 of the second embodiment is integrally provided over the width direction of the back wall 12B of the box 12 has been described. However, the configuration is not limited to this configuration, and a plurality of small scanner devices are provided. Alternatively, it may be configured to be individually controllable. Thereby, the partial fraud detection process of the outer surface of the back wall 12B of the box 12 can be executed by moving only the scanner device corresponding to the part where the presence / absence of fraud is desired to be detected. In particular, when an obstacle (accessory) that is not an illegal object is provided on the back wall 12B of the box 12, only the scanner device that does not have an obstacle (accessory) on the movement trajectory of the scanner device is moved. By doing so, it is possible to execute fraud detection processing that matches the outer surface environment of the back wall 12B of the box 12.

  Further, the scanner device may be provided in the vertical direction of the back wall 12B of the box 12 and the scanner device may be moved along the horizontal direction of the back wall 12B of the box 12.

  Further, the “fraud detection process” of the present invention is not limited to the above-described embodiments, and in a gaming machine having a box-shaped housing, an illegal object is attached to the outer surface of the box, and an illegal opening is made. If there is a risk of fraudulent acts such as, if the process allows the administrator to recognize the presence of fraud without removing the gaming machine from the island facilities, etc. May be.

  Moreover, in each embodiment mentioned above, although it was set as the structure which detects fraud with respect to the backplate on the back side of a box, it is not limited to this, It is with respect to the side of a box (both side plates of a box) Thus, the fraud detection may be performed by the fraud detection process. Moreover, it is good also as a structure which detects both a back board and a side board, and fraud detection with a higher precision is attained by this structure.

  In each embodiment described above, the function of each gaming member is stopped as a means for stopping the progress of the game, but the means for stopping the progress of the game is not limited to this, The following configuration may be used.

  First, when the power switch of the power supply unit 78 is activated, power is supplied to the sub control board unit 50 first, not the main control board unit 66. Then, the fraud detection process is started on the outer surface of the box by the sub-control board 52. That is, for fraud detection, such as fraud detection processing (laser fraud detection by laser light, fraud detection by scanner), storage means for storing the normal state of the outer surface of the box, determination means for determining the presence or absence of fraud, etc. The sub-control board 52 is provided with a series of functions. Then, after the series of fraud detection processing is completed by the sub control board 52, the sub control board 52 transmits the fraud determination result to the power supply unit 78. Then, the power supply unit 78 supplies power to the main control board unit 66 when the sub control board 52 finds no fraud. On the other hand, when an irregularity is detected by the sub control board 52, power supply to the main control board unit 66 is not performed. Thereby, when fraud to the box is detected, the game cannot be started. As a result, it is possible to reliably prevent the game from proceeding in a state in which the box is cheated.
