In the variation display of the decorative symbol, a more complicated effect than the variation display of the first special symbol and the second special symbol is executed.

  Here, game play based on the game board 400 will be briefly described. The game state is roughly divided, and the winning probability of the jackpot lottery related to the first special symbol and the second special symbol is low, and the time is shortened in the variation display of the first special symbol and the second special symbol accompanying the jackpot lottery. The probability of winning the jackpot lottery related to the normal gaming state and the first special symbol and the second special symbol is higher than the normal gaming state, and the variation of the first special symbol and the second special symbol accompanying the jackpot lottery The probability variation gaming state in which the time is shortened in the display, and the winning probability of the jackpot lottery relating to the first special symbol and the second special symbol is the same low probability as the normal gaming state, and the first special symbol associated with the jackpot lottery or The first special symbol and the second symbol in the short-time gaming state in which the time is shortened in the variation display of the second special symbol and the gaming state of any one of the normal gaming state, the probability variation gaming state, and the short-time gaming state. It is classified into a special game state to migrate to if you won the jackpot lottery according to any one of the different pattern. In the main control board 920, a random number for lottery lottery, a random number for lottery type lottery, a random number for lottery lottery, a random number for variation pattern lottery, a random number for variation time addition pattern lottery are generated, and various game states When a game ball enters the first starting prize-winning device 431, a jackpot lottery random number and a jackpot type lottery random number are acquired and stored in a predetermined area of the main control board 920 RAM. At this time, if the first special symbol or the second special symbol is not in the variable display or final display, immediately before the first special symbol or the second special symbol is in the variable display or final display, the preceding After winning all the jackpot lottery rights that have been won, the winning jackpot lottery will be won based on the acquired random number for the jackpot lottery and the current gaming state (normal gaming state, probability variation gaming state or short-time gaming state) It is determined whether or not. In the case of winning the jackpot lottery, the stop symbol of the first special symbol is further determined based on the random number for the lottery type lottery, and if the stop symbol is a symbol corresponding to the specific symbol, the special gaming state is entered. After the transition, it becomes a probability jackpot that shifts to the probability variation gaming state, and when the stop symbol is a symbol corresponding to the non-specific symbol, it becomes a normal jackpot that shifts to the short-time gaming state after transitioning to the special gaming state. On the other hand, in the case of being lost in the jackpot lottery, a lost symbol is set as the stop symbol.

  After the jackpot lottery pertaining to the first special symbol, the current gaming state, the lottery result of the jackpot lottery, the random number for the stop pattern lottery, the random number for the variable time addition pattern lottery, the jackpot pertaining to the first special symbol and the second special symbol The variation display time of the first special symbol is determined and the variation pattern of the decorative symbol is selected on the basis of the number of reserved lottery rights. After that, the variable display of the first special symbol and the decorative symbol is started, the variable display by the constant pattern is continued over the variable display time in the first special symbol, and the selected variation is displayed in the decorative symbol. Variation display according to the pattern is executed. When the stop symbol is confirmed and displayed as the first special symbol as the variable display time elapses, or when the decorative symbol variable display is finished and the stop symbol is a symbol corresponding to a specific symbol and a non-specific symbol. , The probability variation symbol and the short time symbol are confirmed and displayed, respectively. The final display of the first special symbol and the decorative symbol is continued for a certain time.

  If the stop symbol of the first special symbol is a lost symbol after the final display of the first special symbol, the gaming state is maintained in the normal gaming state, and the stop symbol of the first special symbol is a specific symbol or a non-specific symbol. If the symbol corresponds to one of the symbols, the gaming state shifts to a special gaming state. In the special game state, the open / close shutter 453 of the big winning device 433 is intermittently shifted to the entry allowable configuration a predetermined number of times. After the opening / closing shutter 454 shifts to the approaching allowable configuration, the opening / closing shutter is activated depending on whether a predetermined number (for example, 10 balls) of game balls have entered the big winning device 433 or a predetermined maximum time has elapsed. 454 shifts to an entry prohibition state. Thereafter, after the elapse of a predetermined time, the open / close shutter 454 again shifts to the entry allowable configuration. This operation is repeated a predetermined number of times. In the special game state, the big hit lottery related to either the first special symbol or the second special symbol is not executed. After the special gaming state, if the current jackpot type is a promising jackpot, the game shifts to a probabilistic gaming state, and if the current jackpot type is a normal jackpot, the system shifts to a short-time gaming state. When transitioning to the probability variation gaming state based on the probability variation jackpot, the probability variation gaming state is maintained until the next jackpot lottery win according to either the first special symbol or the second special symbol. On the other hand, when shifting to the short-time gaming state based on the normal jackpot, the right of the jackpot lottery for a predetermined number of times is consumed without winning the jackpot lottery for either the first special symbol or the second special symbol. The short-time gaming state ends and the normal gaming state is entered.

  In the above, the jackpot lottery related to the first special symbol has been described, but since the same applies to the jackpot lottery related to the second special symbol, the first special symbol and the second special symbol are respectively the second special symbol and the second special symbol. The description which overlaps as it replaces and reads 1 special symbol is abbreviate | omitted.

  When a game ball enters the first starting device 435 in various gaming states, a random number for winning lottery is acquired and stored in a predetermined area of a RAM (not shown) of the main control board 920. At this time, if the normal symbol is not in the variable display or final display, immediately after that, or if the normal symbol is in the variable display or final display, all the winning lottery rights acquired in advance will be consumed. Later, it is determined whether or not the winning lottery is won based on the acquired random number for winning lottery and the current gaming state (normal gaming state, probability variation gaming state or short-time gaming state). In the probability variation gaming state and the short-time gaming state, the winning probability of the winning lottery is higher than that in the normal gaming state. When a winning lottery is won, a predetermined winning symbol is set as a stop symbol, and when a winning lottery is not won, a predetermined lose symbol is set as a stopped symbol. After winning the lottery, the normal symbol variation display is started, and in the normal gaming state and special gaming state, the variation display in a certain pattern is continued for a predetermined time, and in the probability variation gaming state and the short-time gaming state. Is continuously displayed in the same pattern as the normal gaming state for a predetermined time shorter than the normal gaming state. As the predetermined time corresponding to the gaming state elapses, the stop symbol is fixedly displayed over a certain period of time as a normal symbol.

  If the stop symbol is a winning symbol after the normal symbol confirmation display, the movable blade 452 of the second start winning device 432 shifts to the entry allowable configuration at least once. Specifically, in the case of winning in the normal gaming state or the special gaming state, the movable blade 452 typically shifts to the entry allowable configuration for a predetermined time by a predetermined number of times (for example, once). In the case of winning in the probable gaming state or the short-time gaming state, the movable blade 452 is typically more than the normal gaming state or the special gaming state by a predetermined number of times (for example, three times) than the normal gaming state or the special gaming state. The system shifts to the allowed access configuration for a long predetermined time. However, when a predetermined number (for example, 10 balls) of game balls enter the second start winning device 432, the movable blade 452 forcibly shifts to the entry prohibition state and is based on the winning of the current winning lottery.

(Electric configuration of game machine and various control processes)
Next, the electrical configuration of the gaming machine 100 will be described. FIG. 10 is a block diagram illustrating an example of an electrical configuration of the gaming machine. As shown in FIG. 10, the gaming machine 100 includes control devices such as a power supply / launch control device 900, a power supply monitoring board 910, a main control board 920, a payout control board 930, and a sub control board 940. In FIG. 10, a circuit device that merely relays various signals is omitted. In the following, these main devices will be described in detail individually.

  The power supply / launch control device 900 includes a power supply unit 901 that supplies power of a predetermined voltage to each part of the gaming machine 100 via a power supply path (broken line in the figure), and a launch device according to the operation of the launch operation device 250. A launch control unit 902 that controls the driving of 330, and a signal relay unit 903 that relays a forced initialization signal and a ball overflow signal output from the initialization switch 907 and the ball overflow switch 249 according to the operating state of the initialization switch 907 and the ball overflow switch 249, respectively. ing.

  The power supply unit 901 takes in external power (for example, AC 24 volts) supplied from the outside and converts it into internal power (for example, DC 24 volts), and uses various devices such as various solenoids and various motors from the internal power. Power for driving voltage (for example, DC 12 volts), power for control voltage for driving various switches and executing control processing (for example, DC 5 volts), main control board The power of the backup voltage for holding the contents of the RAM of 920 and the payout control board 930 is generated and supplied to the power supply monitoring board 910, the main control board 920, the payout control board 930, the sub control board 940, and the like. Specifically, internal power, drive voltage, control voltage, and backup voltage power are supplied to the power supply monitoring board 910, and drive voltage, control voltage, and backup power are supplied to the main control board 920. The power of the backup voltage is supplied via the power supply monitoring unit 911 of the power supply monitoring board 910, and the driving voltage and the control voltage power are directly supplied to the payout control board 930 and the sub control board 940. The firing control unit 902 is supplied with driving voltage and control power. A power switch 909 is connected to the power supply unit 901. When the power switch 909 is in an off state, the external power capture is stopped. The power supply to the inside of the gaming machine 100 is stopped by turning off the power switch 909 or removing the power plug connected to the power supply unit 901 via the power switch 909 from the external power supply outlet. A case where the power supply is stopped or a case where the supply of the external power itself is stopped is collectively referred to as a “power failure state”. The power supply unit 901 is configured to normally output power of a predetermined voltage for a predetermined period even after the occurrence of a power failure. As a result, the main control board 920 and the payout control board 930 can save the state and finish the control so that the current control state can be restored.

  The firing control unit 902 controls driving of the ball feed solenoid 332 and the firing solenoid 334. The game ball is actually ejected by driving the ball feed solenoid 332 and the firing solenoid 334. The ball feed solenoid 332 and the firing solenoid 334 are permitted to be driven when predetermined conditions are met. Specifically, it is detected that the player is touching the firing handle 252 based on the contact sensor signal from the contact sensor 254, and the firing stop switch 255 for stopping the firing is not operated. On the condition, the firing control unit 902 outputs a firing permission signal in an on state to the main control board 920. Further, the main control board 920 outputs a firing solenoid control signal and a ball feed solenoid control signal to the launching device 330 based on the launch permission signal and the launch abnormality signal. As a result, the launching device 330 drives the launching solenoid 334 in response to the launching solenoid control signal, and as a result, the game ball is launched with a strength corresponding to the rotational operation amount of the firing handle 252 (resistance value of the variable resistor 253). The

  When the initialization switch 907 is pressed, the signal relay unit 903 outputs an on-state forced initialization signal to the main control board 920. In the main control board 920, the stored information stored in the RAM of the main control board 920 is initialized in response to the reception of the on-state forced initialization signal. Further, when the ball overflow switch 249 detects a game ball, the signal relay unit 903 outputs an on-state ball overflow signal to the main control board 920. The main control board 920 outputs a low-speed payout signal to the payout control board 930 based on the detection of the ball overflow signal in the ON state, and the payout control board 930 that has received the low-speed payout signal from the payout device 540 The game ball payout speed will be reduced. Conversely, a high-speed payout signal is output to the payout control board 930 based on the detection of the ball overflow signal in the off state, and the payout control board 930 that has received the low-speed payout signal receives the game ball payout speed from the payout device 540. Will be speeded up.

  The power monitoring board 910 monitors the power supply state from the power supply / launch control device 900, and outputs a power failure signal to the main control board 920 and the payout control board 930 in response to the occurrence of a power failure state, A signal relay unit 912 that relays power supply and transmission of various signals between the power source / launch control device 900 and the main control board 920 is included. The power supply monitoring unit 911 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 901, and determines that a power failure has occurred when this voltage is less than 22 volts. The signal is output to the main control board 920 and the payout control board 930. The main control board 920 and the payout control board 930 recognize the occurrence of a power outage by receiving an on-state power outage signal.

  The main control board 920 comprehensively controls the operation of the gaming machine 100. On the main control board 920, an MPU as a one-chip microcomputer is mounted. The MPU includes a CPU as an arithmetic processing unit, a ROM that stores various control programs and fixed data executed by the CPU, and a RAM that temporarily stores various data when the control program is executed. . In addition, the main control board 920 is mounted with various circuits such as a timer circuit, a counter circuit, a clock generation circuit, and a signal transmission / reception circuit. The RAM of the main control board 920 is configured to hold (back up) internal data by supplying power of a backup voltage from the power / launch control device 900 even after shifting to a power failure state.

  The payout control board 930 controls a game ball payout operation by the payout apparatus 540 according to an instruction from the main control board 920 and a game ball lending operation by the payout apparatus 540 according to an operation of the game ball lending apparatus 290. As with the main control board 920, the payout control board 930 is mounted with various circuits such as an MPU as a one-chip microcomputer, a timer circuit, a counter circuit, a clock generation circuit, and a signal transmission / reception circuit. Similarly to the RAM of the main control board 920, the RAM constituting the MPU of the payout control board 930 is configured to hold internal data even in a power failure state.

  The sub control board 940 controls operations of various rendering devices, various light emitting devices, various acoustic devices, and the like based on instructions from the main control board 920.

Each of FIGS. 22A and 23A shows the unsealed state of the substrate case, and each of FIGS. 22B and 23B shows the sealed state of the substrate case. As shown in FIGS. 21A and 21B, the pair of connection fixing members 603 are fixed to the pair of connection fixing portions 613 with screws 693 and the like, and the pair of connection fixing members 604 are A pair of connecting and fixing portions 624 are fixed in a cavity 624A (see FIG. 22A) with screws 694 or the like. Both the pair of connecting and fixing members 602 and the pair of connecting and fixing members 603 are made of a material having a high rigidity. Each coupling fixing member 603 is formed with an engaging claw 631 (only in FIG. 21A), while each coupling fixing member 604 is formed with an engaging claw 641. When the relative position of the housing member 601 and the lid member 602 changes from the opened state shown in FIGS. 22A and 23A toward the sealed state, the pair of connection fixing members 603 and the pair of connection fixing portions 613 enters the cavity 624A of the pair of connection fixing portions 624, and the connection claws 631 of the pair of connection fixation members 603 are inserted while elastically deforming the connection claws 641 of the pair of connection fixation members 604 so that the bending angle becomes small. The Finally, when the connecting claw 631 advances beyond the connecting claw 641 and the pressing of the connecting claw 641 by the connecting claw 631 is released, the connecting claw 641 returns to its original shape by plastic reverse deformation. As shown in FIG. 22B and FIG. 23B, the distal end of the coupling claw 641 is disposed closer to the bent end of the coupling claw 631 than the distal end of the coupling claw 631. As a result, once the housing member 601 and the lid member 602 are sealed, even if the relative position between the housing member 601 and the lid member 602 is changed toward the opened state, the coupling claw 631 and the coupling claw 641 The engagement is prevented by the engagement. Accordingly, the housing member 601 and the lid member 602 are connected and fixed in a self-aligning manner so that they cannot be opened by their transition to the sealed state.

Here, the bearing structure 40 and the engagement between the bearing structure 40 and the shaft structure 30 will be described in detail. 24A and 24B are exploded perspective views illustrating an example of a bearing structure. FIG. 25 is a cross-sectional view taken along the line AA ′ in FIG. 11 showing an engaged state between the bearing structure and the shaft structure.
As shown in FIG. 24, the bearing structure 40 includes a first bearing forming member 41 extending from the housing member 601, a second bearing hole forming member 42 extending from the lid member 602, 1 includes a reinforcing member 43 disposed in the internal space of the bearing forming member 41 and a shaft fixing member 44 disposed in the internal space of the reinforcing member 43 and prohibiting the shaft structure 30 from being removed from the bearing structure 40. Yes.

  In the first bearing hole forming member 41, as shown in FIG. 24B, a semi-cylindrical thick bearing groove 41A, a rectangular parallelepiped space forming groove 41B located above the thick bearing groove 41A, A semi-cylindrical fine bearing groove 41C that is thinner than the thick bearing groove 41A is formed, and the second bearing hole forming member 42 has a semi-cylindrical thick thickness as shown in FIG. A bearing groove 42A and a semi-cylindrical fine bearing groove 42C which is positioned above the thick bearing groove 42A and is thinner than the thick bearing groove 42A are formed, and a bearing hole 40A formed in the bearing structure 40 (see FIG. 25). ) Is a cylindrical through hole formed by the thick bearing groove 41A and the thick bearing groove 42A, a rectangular parallelepiped through space formed by the thick bearing groove 41B and the thick bearing groove 42A, and communicated with the thick through hole; Narrow bearing Formed by grooves 41C and fine bearing groove 42C, it is composed of a fine sinkhole cylindrical communicating with the through space. The portion that effectively functions as a bearing is a thick through hole formed by the thick bearing groove 41A and the thick bearing groove 42A, and a narrow recess hole formed by the thin bearing groove 41C and the thin bearing groove 42C.

  The reinforcing member 43 has a box shape, and is arranged in the thick bearing groove 41 </ b> B to relieve the shaft fixing member 44 from being deformed by the external force applied to the shaft fixing member 44 and the external force being applied to the housing member 601. The shaft fixing member 44 has a bent shape in which one end is inclined toward the second bearing hole forming member 42 with the bent portion as a boundary. The reinforcing member 43 and the shaft fixing member 44 are fixed to the first bearing forming member by screws 49 or the like. The reinforcing member 43 and the shaft fixing member 44 are made of a material having a higher rigidity than at least the housing member 601.

  As shown in FIG. 25, in the state where the shaft structure 30 is inserted, the tip of the shaft fixing member 44 that is inclined and projecting toward the second bearing hole forming member 42 is the periphery of the first thin shaft portion 32. Therefore, it is disposed below the second thick shaft portion 33. After the shaft structure 30 is inserted into the bearing structure 40, that is, after the main controller 370 is mounted on the mounting base 360 (see FIG. 11), the bearing structure 40 and the shaft structure 30 will be separated from each other. First, the tip of the shaft fixing member 44 comes into contact with the second thick shaft portion 33, and then plastically deforms so that the bending angle of the shaft fixing member 44 increases, and the second thick shaft portion 33 The contact portion moves to the shaft center side, and finally, the tip of the shaft fixing member 44 contacts the boundary portion between the first thin shaft portion 32 and the second thick shaft portion 33. In this state, even if a larger external force is applied, it becomes extremely difficult to further plastically deform the shaft fixing member 44, and before the shaft fixing member 44 is deformed or damaged, other parts, for example, A part of the first bearing hole forming member 41, in particular, a wall of a portion to which the screw 49 is fixed and a connecting portion between the first bearing hole forming member 41 and the housing member 601 are damaged. Note that these parts that are easily damaged are at positions that are relatively easy to confirm from the back side of the gaming machine 100. Further, when the main control device 370 is removed for a normal purpose such as when the main control board 920 fails, as shown in FIG. 24A, a plurality of the first bearing hole forming members 41 are formed. What is necessary is just to cut | disconnect so that a small hole may be connected and to take out the reinforcement member 43 and the shaft structure 44 collectively. Further, the bearing hole 40A of the bearing structure 40 includes a first bearing hole forming member 41 and a second bearing hole forming member 42 that are associated with the engagement of the housing member 601 and the lid member 603 by relative translation (sliding). Therefore, the shaft structure 30 may be inserted into the bearing structure 40 if the relative translation between the housing member 601 and the lid member 603 is not completed. Can not. Conversely, when the shaft structure 30 is inserted into the bearing structure 40, the relative translational movement between the first bearing hole forming member 41 and the second bearing hole forming member 42 cannot be performed.

  As can be seen from a comparison between FIG. 9 and FIG. 10, FIG. It is covered with a protective cover part 503. Further, the distance between the surface of the bearing structure 40 on the protective cover portion 502 side and the surface of the protective cover 503 on the bearing structure 40 side is such that the reinforcing member 43 and the shaft structure 44 are integrated when the main controller 370 is removed. Less than the required travel distance for removal.

  As shown in FIGS. 19 and 20, the main control device 370 is necessary for inserting various connectors 99 formed in the main control board 920 with the size of the through hole 610 </ b> A penetrating the board housing portion 610. An opening restricting member 60 that includes a plate-like opening restricting portion 61 that is limited to a plurality of through holes 61A to 61D, and is disposed closer to the main control board 920 than the through hole 610A in correspondence with the through hole 610A; A connector covering member 70 that includes a bent connector covering portion 71 that covers the connector 99 and is disposed on the opposite side of the main control board 920 from the through hole 610A in correspondence with the through hole 610A is provided. The plurality of through holes 61 </ b> A to 61 </ b> D of the opening restricting portion 61 are configured according to the shape and number of connectors to be inserted, so that an excessive gap is not formed between the connector 99 and the opening restricting portion 61 as much as possible. Is formed. The connector covering portion 71 covers the front of the front end side and the lower side surface of all the connectors 99 mounted on the main control board 920.

  Here, the hole restricting member 60 and the connector covering member 70 will be described in detail. 26 to 28 are a perspective view, an exploded perspective view, and a front view illustrating an example of the hole restricting member and the connector covering member, respectively. 29 to 31 are a cross-sectional view, a partial cut perspective view, and a partial cross-sectional view, respectively, taken along the line BB ′ in FIG. 28, and FIGS. It is the partial cutting | disconnection perspective view and sectional drawing with respect to a cut surface.

  As shown in FIG. 26 and FIG. 27, the opening restriction member 60 includes a pair of locking claws 62 protruding from the opening restriction part 61 toward the connector covering member 70, and the opening restriction part 61. A pair of movement restricting portions 63 protruding from the hole restricting portion 61 toward the connector covering member 70, and a return wall portion 64 (see FIG. 19) protruding while bending from the lower end of the opening restricting portion 61 toward the connector covering member 70. Is included. In addition, each latching claw part 62, each position control part 63, and the return wall part 64 are integrally formed with the hole control part 61. The shape of the return wall portion 64 is substantially the same as the shape of the opposing portion in the substrate housing portion 610 (see FIG. 19), and blocks the path that reaches the main control substrate 920 linearly from the lower end of the through hole 610A. doing.

  As shown in FIGS. 26 and 27, the connector covering member 70 is a pair of engaging cylinders disposed together with the connector covering portion 71 so as to correspond to the pair of locking claw portions 62 of the hole restricting member 60. Reinforcing walls disposed on both sides of each of the pair of position restricting portions 63 and the pair of engaging tube portions 72, the portion 72, the pair of movement restricting portions 63 of the opening restricting member 60 74. The connector covering member 70 is formed with an opening formed in the connector covering portion 71 and an opening of the engagement cylinder portion 72, and a through hole 72A penetrating the connector covering member 70 is formed. The engaging claw 62 is inserted into 72A as shown in FIG.

  As shown in FIGS. 29 to 31, a step for changing the width of the opening small toward the opening restriction member 60 side is provided in the vicinity of the middle of the engagement cylinder portion 72. When the front end of the locking claw 62 is engaged, movement of the connector covering member 70 in the direction of detachment with respect to the hole restricting member 60 is prohibited. The movement in the mounting direction is restricted by the contact of the connector covering portion 70, the engagement tube portion 72, the reinforcing wall 74 and the hole restricting member 60. Further, since the movement restricting portion 63 is arranged corresponding to the notch on the tip side of the movement restricting portion 73, the upward movement of the connector covering member 70 with respect to the hole restricting member 60 is the same as the movement restricting portion 73. It is restricted by contact with the movement restricting portion 63. Note that the movement of the connector covering member 70 in the left-right direction with respect to the hole restricting member 60 is restricted by the contact of the housing cover 601 with the distal end of the connector covering member 70 in the left-right direction. Further, even if the vicinity of the center upper end of the connector covering portion 71 is pressed and the connector covering member 70 is bent, the reinforcing wall 74 disposed on the center side of the engaging tube portion 72 receives the pressing load. In addition, the load on the engagement cylinder part 72 and the engagement claw part 63 is significantly reduced, and the damage to the engagement cylinder part 72 and the engagement claw part 63 is prevented.

  When the connector covering member 70 is detached from the opening restricting member 60, the connector covering member is inserted in a state where an operation instrument such as a driver is inserted from the through direction of the through hole 72A and the pair of locking claws 62 are bent. The connector covering member 70 is moved in the disengagement direction by picking the upper end of 70. The engaging claw portion 62 does not penetrate the through hole 72A, that is, the protruding tip of the engaging claw portion 62 is disposed inside the opening of the engaging cylinder portion 72, and other than the through direction of the through hole 72A. Depending on the operation from, the engagement between the locking claw portion 62 and the engagement tube portion 72 cannot be substantially released.

  32 and 33, the connector covering member 70 has a surface on the side opposite to the lid member 602 of the connector covering member 70 on the side closer to the lid member 602 than the surface on the opposite side to the lid member 602 of the housing member 601. It is arranged to become.

  The connector covering member 70 is entirely covered with a protective cover portion 503 of the base body 501 as can be seen from a comparison between FIG. Further, the distance between the surface of the connector cover member 70 on the protective cover portion 502 side and the surface of the protective cover 503 on the connector cover member 70 side is the moving distance necessary for separating the connector cover member 70 from the opening restricting portion 60. Is less than.

  In the case of the gaming machine 100 described above, the main control device 370 is rotatably supported and fixed, so that it is possible to suppress an illegal act of removing the main control device 370 and replacing the main control board 920. The configuration of the back side of the intermediate block 103 and the removal trace of the main control device 370 can be easily confirmed. In addition, the main control device 370 is cantilevered to support and fix the main control device 370 so that the main control device 370 can rotate freely. Even if the main control device 370 is easily displaced, the rear block 104 is an intermediate block. In the closed state in which the connector 99 is closed, the connector 99 is covered with the connector covering member 70, and further, the connector covering member 70 is covered with the base 501 (protective cover portion 503) of the rear block 104, A foreign object is inserted from between the base body 501 of the rear block 104 and the main controller 370 to disconnect between the connector 99 and the wiring connected to the connector 99 (illegal connection disconnection). Similarly, the wiring itself Disconnecting (unauthorized wiring disconnection) or inserting an unauthorized substrate (not shown) between the connector 99 and the wiring ( Positive substrate insertion), fraud is reliably suppressed or tampered the received signal received by the signal and the main control board 920, which is transmitted from the main control board 920. Further, since the main control device 370 is rotatably supported and fixed, and the main control device 370 can be visually observed both on the front side and the back side, these illegal acts can be easily confirmed.

  Further, in the case of the gaming machine 100 described above, only a portion that is different from the front side of the projecting side from the main control board 920 of a main electronic component (not shown) such as an MPU in which the protective cover portion 503 is disposed below the connector 99 is provided. And the connector covering member 70 covers the tip of the connector 99 protruding from the main control board 920 and the side of the main electronic component (lower side). It becomes even more difficult to execute fraudulent acts such as illegal board insertion.

  In the case of the gaming machine 100 described above, since the connector covering member 70 is detachably attached to the hole restricting member 60, the connection state between the connector 99 and the wiring is changed (from the connector to the wiring). Deterioration of operability is suppressed in normal maintenance inspections that require removal and insertion of wiring into the connector.

  Further, in the case of the gaming machine 100 described above, since the distance between the connector covering member 70 and the connector 99 in the facing direction is less than the distance (insertion / extraction distance) necessary for removing the wiring from the connector 99, the connector covering member In the mounted state, the connection state between the connector 99 and the wiring cannot be changed, the disconnection between the connector 99 and the wiring, the disconnection of the wiring itself, or the unauthorized insertion of the board between the connector 99 and the wiring. It becomes even more difficult.

  Further, in the case of the gaming machine 100 described above, a part of the protective cover portion 503 of the base body 501 is less than the distance necessary for the movement in the front in the moving direction for detaching the connector covering member 70 from the hole restricting member 60. Since the connector covering member 70 cannot be detached unless the rear block 104 is opened to the intermediate block 103 in order to cover them apart, the disconnection between the connector 99 and the wiring, the disconnection of the wiring itself, the connector It becomes even more difficult to insert an illegal substrate between 99 and the wiring.

  Further, in the case of the gaming machine 100 described above, the intermediate block 103 includes a mounting base 360 that is rotatably fixed to the gaming board 400 via the bearing structure 10 and the shaft structure 20, and the main control device 370 includes: The main control device 370 and the mounting base 360 are integrally rotated so that the main control is performed because the main control device 370 and the mounting base 360 are rotated together by a support mechanism including the shaft structure 30 and the bearing structure 40. The configuration on the back side of the invisible game board 400 covered with the device 370 can be easily expressed. In addition, since only the main control device 370 can be rotated to expose the back surface of the main control device 370, maintenance and inspection of members on the back side of the game board 400 covered by the main control device 370 can be performed. It can be executed easily, and it can be easily confirmed whether or not an unauthorized substrate is mounted on the back side of the main control device 370.

  In addition, since the gaming machine 100 includes the hole restricting member 60, it is possible to easily suppress an illegal act on the plurality of connectors 99. Furthermore, even if the number of connectors and the connector shape are different for each model, it is possible to cope with the problem by changing the configuration of the through-holes (corresponding to the through-holes 61A to 61D) of the opening restriction member 60, so that versatility is enhanced.

  Further, in the case of the gaming machine 100 described above, the opening restriction is performed by the engagement between the pair of locking claws 62 of the opening restriction member 60 and the step in the cavity of the pair of engagement cylinders 72 of the connector covering member 70. In order to restrict the attachment / detachment of the connector covering member 70 from the member 60, the connector covering member 70 can be easily attached and detached from the hole restricting member 60.

  Further, in the case of the gaming machine 100 described above, since the tips of the pair of locking claws 62 are disposed in the cavities of the pair of engaging cylinders 72, the connector covering member 70 is attached and detached from the rear block. Although it becomes simple when the rear block 104 is closed, it becomes difficult when the rear block 104 is closed, and the removal of the connector covering member 70 that is executed as a pre-stage of an illegal act on the connector 99 is suppressed. Cheating is suppressed.

  Further, in the case of the gaming machine 100 described above, the movement restriction member 64 of the hole restriction member 60 and the movement restriction portion 74 of the connector restriction member 70 are provided, so that the upward movement of the connector covering member 70 is restricted. For this reason, it is possible to suppress an illegal act of shifting the connector covering member 70 and attempting to make an unauthorized modification to the connector 99 and the wiring connected to the connector 99.

  Further, in the case of the gaming machine 100 described above, by providing the reinforcing wall 74, even if an external force is applied to the connector covering member 70 to break the engagement between the connector covering member 70 and the hole restricting member 60, Damage to the claw part 62 or the engagement cylinder part 72 is suppressed.

  In the above description, the configuration in which the countermeasure against fraud of the present invention is taken for all the connectors 99 provided on the main control board 920 has been described. However, in the present invention, some connectors provided on the main control board 920, in particular, Connectors electrically connected to devices involved in the acquisition of a game ball by a player, for example, a first start winning device 441, a second starting winning device 442, a blade opening / closing solenoid 462, a shutter opening / closing solenoid 463, and a payout control device 560 It can also be set as the structure applied only to.

  In the above, the case where the present invention is applied to the main control device 370 has been described. However, in the present invention, other control devices, in particular, the control of the payout control device 560 involved in the acquisition of the game ball by the player, It can also be applied to a device.
