As shown in FIG. 19 (a), the sphere detection sensor D has a basic configuration including a sensor body 82 having an oscillation circuit and the like, and a sphere passage port 83 through which a coil is provided and through which a pachinko sphere can pass. As shown in FIG. 19 (b), the ball detection sensor D oscillates in a state where the pachinko ball is not detected (a state where the pachinko ball does not pass through the ball passage opening 83) and the high level signal is detected. It is set to output a signal (hereinafter referred to as a high level signal). On the other hand, when the ball detection sensor D is detecting a pachinko ball (while the pachinko ball is passing through the ball passage opening 83), the oscillation of the oscillation circuit is stopped or attenuated, and a low-level signal (hereinafter referred to as a low level signal). Is called a low level signal).

That is, the fraud detection device 84 of the embodiment also uses the case body 51 in which the first starting ball detection sensor 53 is disposed as a case body that houses the detection sensor unit 85 and the metal ball for detection 86.

  The detection sensor unit 85 is basically composed of a rectangular sensor device main body 87 and a cylindrical detection port (sphere passage port) 87a in which a through-hole is defined. The same ball detection sensor D provided in the second start winning devices 44, 46, the special winning device 47, etc. is employed. The diameter of the opening circle of the detection port 87a is set slightly larger than the diameter of the metal ball for detection 86 (see FIG. 10). A detection coil 88 is wound around the detection opening 87a along the opening edge, and the detection coil 88 generates a magnetic field around the detection opening 87a. As shown in FIG. 20, the sensor device main body 87 includes an oscillation circuit F, an oscillation detection circuit G, and an output circuit H. As shown in FIG. 21 (a), the oscillation circuit F oscillates at a high frequency (for example, 1 MHz) in a state where no magnetic substance (detection metal sphere 86) exists in the magnetic field of the detection port 87a. ing. As shown in FIG. 21B, when a magnetic body (detection metal sphere 86) is present in the magnetic field of the detection port 87a, the oscillation circuit F stops or attenuates oscillation. The oscillation circuit F according to the embodiment is set to stop the oscillation in a state where the magnetic body (detection metal ball 86) is present in the detection port 87a.

  The oscillation detection circuit G detects the oscillation state of the oscillation circuit F and outputs a signal corresponding to the oscillation state. As shown in FIG. 21A, when the oscillation detection circuit G detects the oscillation of the oscillation circuit F, it outputs an oscillation detection signal to the output circuit H, and as shown in FIG. Is configured to output an oscillation stop detection signal to the output circuit H when it detects oscillation stop or attenuation (in the embodiment, oscillation stop). That is, the detection sensor unit 85 includes an oscillation detection state (first state) in which the oscillation detection circuit G detects oscillation, and an oscillation non-detection state (first state) in which the oscillation detection circuit G detects oscillation stoppage depending on the presence or absence of a magnetic material. The state can be changed to 2 states).

  The output circuit H outputs the high level signal when the oscillation detection signal is input from the oscillation detection circuit G, and outputs the low level signal when the oscillation stop detection signal is input from the oscillation detection circuit G. It is designed to output. As shown in FIG. 21B, the low level signal has a value slightly larger than zero. The output circuit H is electrically connected to the main controller 31 via a relay board (not shown), and the high level signal and the low level signal output from the output circuit H are input to the main controller 31. The The metal ball for detection 86 stops the oscillation of the oscillation circuit F and maintains the detection sensor unit 85 in the oscillation non-detection state (maintains the state change means in the second state). In the embodiment, a pachinko ball that is a magnetic material is used as the metal ball for detection 86. As will be described later, the metal ball for detection 86 is accommodated in the case body 51 in a state of being located in the detection port 87a (see FIG. 10).

  That is, in the fraud detection device 84 of the embodiment, the oscillation of the oscillation circuit F is stopped by the detection metal ball 86 in the normal state where the illegal radio wave action is not performed, and the detection sensor unit 85 is in the oscillation non-detection state. Maintained. Therefore, as shown in FIG. 22, the oscillation detection circuit G outputs an oscillation stop detection signal and a low level signal is output from the output circuit H, so that a low level signal is always input to the main controller 31. Is done. On the other hand, when the detection sensor unit 85 is in an oscillation non-detection state, when a radio wave is radiated from the radio wave generator E to the detection sensor unit 85, the oscillation circuit F stops oscillation as shown in FIG. In spite of this, intermittent oscillation is forcibly caused by radio waves. Accordingly, when an illegal radio wave action is performed, the oscillation detection circuit G detects intermittent oscillation and alternately outputs an oscillation detection signal and an oscillation stop detection signal. Thereby, as shown in FIG. 22, the output circuit H alternately outputs a high level signal and a low level signal to the main controller 31. In the fraud detection device 84 according to the embodiment, the detection range of the radio wave in the detection sensor unit 85 is large on the opening direction side (vertical direction in FIG. 24) of the detection port 87a, as shown in FIG. That is, the detection sensor unit 85 is configured to easily react to radio waves radiated from the opening direction of the detection port 87a.

[About the sensor installation portion 61 of the case body 51]
The case body 51 is provided with a sensor installation portion 61 for storing and holding the detection sensor unit 85 and the metal ball for detection 86 on the side of the ball discharge passage 52 (right side in the embodiment). The sensor installation unit 61 includes a rear installation unit 89 provided on the base body 55 and a front installation unit 90 provided on the cover body 56. By attaching the cover body 56 to the base body 55, the front and rear installation units 89 are provided. , 90, the detection sensor unit 85 and the detection metal ball 86 are positioned and held. As shown in FIG. 11, the rear installation portion 89 is provided between a pair of side walls 89a and 89a spaced apart in the left-right direction and the rear end edges of both side walls 89a and 89a, and inclines rearward from the upper side to the lower side. A sensor accommodating portion 89c that opens forward is defined by the rear wall 89b. The rear wall 89b is provided with restricting portions 89d and 89d protruding from the sensor housing portion 89c along the left and right side walls 89a and 89a, and the upper surface of the restricting portion 89d is inclined downward from the rear side toward the front side. doing. Then, one end in the longitudinal direction (wiring connection end) of the sensor device main body 87 in the detection sensor unit 85 is abutted and supported by the restricting portions 89d and 89d, and the rear surface of the sensor device main body 87 is abutted and supported by the rear wall 89b. Thus, the sensor device main body 87 is supported in a posture in which the sensor device main body 87 is inclined backward as it goes from the upper side to the lower side. In addition, a hemispherical ball receiving portion 89 e that is recessed rearward is formed on the rear wall 89 b of the rear installation portion 89 at a position corresponding to the detection port 87 a of the sensor device main body 87.

  As shown in FIG. 12, the front installation portion 90 has a pair of first support portions 90a, 90a that are spaced apart in the left-right direction at intervals facing the inside of the side walls 89a, 89a of the rear installation portion 89. The rear end surface of each first support portion 90a is formed in parallel with the rear wall 89b. Then, with the cover body 56 assembled to the base body 55, as shown in FIG. 10, the first support portion is provided on the front surface of the sensor device main body 87 in the detection sensor unit 85 housed in the sensor housing portion 89c of the rear installation portion 89. 90a and 90a abut, and the detection sensor unit 85 is configured to be positioned in a posture in which the detection sensor unit 85 is inclined backward as it goes from the upper side to the lower side. That is, in a state where the installation member 14 provided with the case body 51 is attached to the game board 12, the detection sensor unit 85 is inclined backward with respect to the board surface of the game board 12 at a predetermined angle (about 60 ° in the embodiment). (A posture in which the opening direction of the detection port 87a is obliquely downward) (see FIG. 8). The positional relationship between the first starting ball detection sensor 53 and the detection sensor unit 85 in the case body 51 is such that the position of the front end of the sensor device main body 87 in the detection sensor unit 85 is on the right side of the first starting ball detection sensor 53. In the front-rear direction, the first start ball detection sensor 53 is set so as to be positioned substantially at the same position as the front end. Further, the detection port 87a of the sensor device main body 87 is above the position where the first starting ball detection sensor 53 is disposed in the front view, and both the detection ports 53a and 87a are substantially aligned in the left-right direction in the plan view. Is set.

  As shown in FIG. 11, the front installation part 90 is provided with a second support part 90b between the first support parts 90a and 90a by denting the wall surface between the first support parts 90a and 90a rearward. It is done. The second support portion 90b is positioned in front of the rear end surfaces of the first support portions 90a and 90a by a predetermined length, and the rear end surface of the second support portion 90b is parallel to the rear end surface of the first support portion 90a. Configured to extend. Then, in a state where the cover body 56 is assembled to the base body 55, the metal ball for detection 86 positioned at the detection port 87a of the detection sensor unit 85 is supported by the second support portion 90b so as to be positioned within the detection port 87a. (See FIG. 10). Further, in the state where the base body 55 and the cover body 56 are assembled, the metal ball for detection 86 supported by the ball receiving portion 89e and the second support portion 90b is held on the sensor installation portion 61 without rattling. At the same time, the center of the detection metal sphere 86 is positioned so as to substantially coincide with the center of the detection port 87a in the opening direction. A support protrusion 90c is provided on the back surface of the cover body 56 above the second support portion 90b. The lower surface of the support protrusion 90c is formed to extend in parallel with the upper surface of the restricting portion 89d. When the cover body 56 is assembled to the base body 55, the lower surface of the support protrusion 90c is the sensor device main body 87. The sensor device main body 87 is sandwiched between the restricting portions 89d and 89d to restrict the vertical movement.

  In a state where the case body 51 is attached to the case installation portion 72 of the installation member 14, the detection sensor unit 85 is located at the lower rear of the game board 12, with the first start winning device 44, the second start winning device 46 and It will be located close to the special prize-winning device 47 (see FIG. 4). Further, since the detection sensor unit 85 is housed in the case body 51 in a posture inclined backward from the upper side to the lower side, the opening direction of the detection port 87a is changed from the rear side to the front side as shown in FIG. It becomes the direction which inclines below toward. That is, by directing the opening direction of the detection port 87 a toward the front lower side of the game board 12, it is possible to easily catch the illegal radio waves radiated from the radio wave generator E set at the front lower side of the game board 12. Although not shown, the detection sensor unit 85 is arranged on the back side of the installation member 14 after the wiring connected to the sensor unit 85 is drawn out to the back side of the case body 51 and then drawn to the back side of the installation member 14. It is connected to the relay board.

[Unauthorized judgment of main controller 31]
As described above, the main controller 31 receives a low level signal from the fraud detector 84 when it is normal (oscillation non-detection state) (see FIG. 22). Further, when the state of the detection sensor unit 85 is changed to the oscillation detection state due to illegal radio wave action, a high level signal is input from the output circuit H. The main controller 31 determines that an illegal radio wave action has occurred when the signal from the fraud detector 84 switches from a low level signal to a high level signal (see FIG. 22). That is, when the detection sensor unit 85, which is maintained in the oscillation non-detection state by the metal ball for detection 86, is changed to the oscillation detection state, the main controller 31 detects an illegal radio wave action.

  Here, when a wire (not shown) derived from the detection sensor unit 85 is cut or pulled out from the detection sensor unit 85 by an unauthorized person (hereinafter referred to as disconnection action), as shown in FIG. No signal is output from the output circuit H (that is, the signal becomes 0). Therefore, the main control device 31 is set to determine that a disconnection action has occurred when there is no output from the output circuit H due to the disconnection action. Further, when a cheating person extracts the metal ball for detection 86 from the detection sensor unit 85 (hereinafter referred to as a ball removal action), the oscillation circuit F oscillates and the detection sensor unit 85 is maintained in the oscillation detection state. . For this reason, the oscillation of the oscillation circuit F is continued even when the radio wave from the radio wave generator E is received, so that a high level signal is continuously output from the output circuit H as shown in FIG. That is, even if the radio wave is received, the signal output from the output circuit H is not switched, and therefore, the illegal radio wave action cannot be detected. Therefore, the main controller 31 determines that a ball removal action has occurred when the output from the output circuit H is switched from a low level signal to a high level signal due to the ball removal action. As for the illegal magnetic action, when the magnetic detection signal is input from the first and second magnetic sensors 79 and 81, the main controller 31 determines the occurrence of the illegal magnetic action.

[Control configuration for fraud determination]
Next, the control configuration of the main controller 31 at the time of fraud determination will be described below. When the main controller 31 detects the occurrence of an illegal radio wave action or an illegal magnetic action including the disconnection action and the ball pulling action, the main control device 31 performs control for notifying the occurrence of the illegal action. That is, the main control device 31 outputs a control signal to the overall control device 19 to notify the symbol display device 15, the lamp device 18, and the speaker 22 of the occurrence of an illegal act. Here, as shown in FIG. 25, in the pachinko machine 10 according to the embodiment, an illegal radio wave action (including a disconnection action and a ball pulling action) and an illegal magnetic action cause the symbol display device 15, the lamp device 18, and the speaker 22 to The operation mode is different. Therefore, the main control device 31 is configured to output a control signal corresponding to the generated illegal act to the overall control device 19. Specifically, when an illegal radio wave action occurs, the display unit 15a of the symbol display device 15 displays a message indicating that the illegal radio wave action has occurred, and causes the speaker 22 to output a sound indicating that the illegal radio wave action has occurred. Further, the lamp device 18 is caused to emit light in the first color (green in the embodiment) to notify the occurrence of illegal radio wave action. When an illegal magnetic act occurs, the display unit 15a of the symbol display device 15 displays the fact that the illegal magnetic act has occurred, and causes the speaker 22 to output a sound indicating that the illegal magnetic act has occurred. Further, the lamp device 18 is caused to emit light in the second color (purple in the embodiment) to notify the occurrence of the illegal magnetic action.

  As shown in FIG. 18, the main controller 31 is electrically connected to a hall computer (notification means) 92 installed in a game room management room or the like via an external terminal board 91 provided on the back side of the pachinko machine 10. Has been. The main control device 31 is set to output a security signal to the hall computer 92 when the illegal radio wave action and the illegal magnetic action are detected. In the embodiment, the same security signal is output in both cases of an illegal radio wave action and an illegal magnetic action. In the hall computer 92, when a security signal is input, the occurrence of fraud is displayed on a display or the like (not shown) of the hall computer 92 so that an administrator or the like is notified of the occurrence of the fraud. Here, no matter what fraud occurs, the same security signal is input to the hall computer 92, so the display contents on the display are the same. However, since the operation modes of the symbol display device 15, the lamp device 18, and the speaker 22 differ depending on the illegal radio wave action and the illegal magnetic action, it is possible to determine which illegal action has occurred.

(Effects of Example)
Next, the operation of the pachinko machine 10 according to the embodiment configured as described above will be described.

  When the player rotates the operation handle 24 provided on the front side of the middle frame 13, pachinko balls launched from the hitting ball launching device 23 are defined by the guide rails 32 provided on the game board 12. It is launched into the game area 33 through the launch passage 32a. At this time, the launch position of the pachinko ball changes according to the amount of rotation of the operation handle 24, and the pachinko ball flows down the first path 33a or the second path 33b of the game area 33 according to the launch position. In a state where the specific condition is not satisfied (a state where a big hit state, a probability variation state, or a time shortening state is not established), the player strikes a pachinko ball so as to be “left-handed” flowing down the first path 33a.

  When pachinko spheres flowing down the first path 33 a enter the sphere introduction part 43, the pachinko spheres are delivered from the sphere introduction part 43 to the stage 42. The pachinko ball rolls left and right on the stage 42 and is then discharged to the game area 33. When the pachinko ball wins the first start opening 45a of the first start winning device 44, the pachinko ball is guided backward through the ball introduction passage 54 and enters the ball discharge passage 52 formed in the case body 51, Finally, it is discharged out of the machine. The pachinko balls that circulate in the ball discharge passage 52 are reduced by the inclination of the front wall 55b that defines the passage 52 and the action of the protrusions 57a and the protrusions 55e of the lid member 57, thereby achieving smooth discharge. .

  When a pachinko ball flowing through the ball discharge passage 52 is detected by the first starting ball detection sensor 53, a symbol variation effect on the symbol display device 15 is started based on the control of the main control device 31, When a predetermined symbol combination is displayed on the display unit 15a of the symbol display device 15 as a result of the symbol variation effect, a big hit occurs. When a big hit occurs, according to the symbol combination displayed on the symbol display device 15, the special winning opening 47 a of the special winning device 47 provided in the game board 12 is opened and the main controller 31 is controlled. Based on this, a big hit effect is performed in the symbol display device 15. When the main control device 31 receives the detection signal from the first starting ball detection sensor 53, the main control device 31 outputs a control signal to the payout control device 29 and causes the ball payout device 28 to pay out a predetermined number of prize balls. .

  In the pachinko machine 10, the various effect devices 70 are controlled by the main control device 31 according to various game states, and the fun of the game is enhanced by the operations and the effects of light. Further, when the LED 60b of the light emitting device 60 disposed in the first start winning device 44 emits light, the light of the LED 60b is irradiated from the back side to the decorative plate body 45b and the start port forming portion 45c of the start port decoration 45. . The first start winning device 44 is a device provided in the pachinko machine 10 because the winning of a pachinko ball triggers the start of symbol variation on the symbol display device 15 or the acquisition of a winning ball. Among them, the player's attention is particularly strongly attracted. That is, by emitting light from the LED 60b of the light emitting device 60, it is possible to brighten the surroundings of the first start opening 45a in the first start winning device 44, which has a high degree of attention of the player, and enhance the interest of the game by the effect. obtain.

  The first start winning device 44 is divided into a start opening 45 with no electric parts and a case body 51 with electric parts such as the first start ball detection sensor 53 and the light emitting device 60, and the start opening 45. Is attached to the game board 12, while the case body 51 is attached to the installation member 14. Therefore, when the start opening 45 is attached to the game board 12, it can be assembled without paying attention to the wiring being pinched between the game board 12 and the work becomes easy. In addition, since the wiring led out from the first starting ball detection sensor 53 and the light emitting device 60 disposed on the case body 51 is connected to the relay board that is drawn out to the back side of the case body 51 and disposed on the installation member 14. When the case body 51 is assembled to the game board 12, the case body 51 can be assembled without paying attention to the fact that the wiring is sandwiched between the game board 12 and the case body 51. That is, the assembly work of the first start winning device 44 to the game board 12 is facilitated.

  The passage wall 45d that defines the ball introduction passage 54 in the start opening 45 is supported by a positioning receiving portion 56a provided in the case body 51 in a state where the installation member 14 is assembled to the game board 12 as shown in FIG. Can be received. Thereby, the ball outlet 54 a of the ball introduction passage 54 and the ball inlet 52 a of the ball discharge passage 52 formed in the case body 51 are aligned and communicated, and the pachinko balls from the ball introduction passage 54 are smoothly transferred to the ball discharge passage 52. The pachinko ball can be surely discharged by letting it through. In addition, as shown in FIG. 7, an inclined guide surface 58a is formed on the upper surface of the bottom wall 58 that receives the pachinko balls from the ball introduction passage 54 in the ball discharge passage 52, and is inclined downward toward the communication port 52b. Therefore, the pachinko sphere that has entered the sphere discharge passage 52 (horizontal passage 52c) from the sphere inlet 52a is promptly passed through the inclined guide surface 58a to the communication port 52b, that is, the detection port 53a of the first starting ball detection sensor 53. It can be guided and detected. As a result, the time until the pachinko ball is detected by the first starting ball detection sensor 53 after winning the first starting port 45a is increased. For example, before the big hit lottery is started by the main control device 31. It is possible to suppress the occurrence of inconvenience and the like that it takes a long time until the gaming state becomes advantageous for the player due to the time required.

  In the pachinko machine 10, when the big hit that satisfies a specific condition, the probability variation state, or the time reduction state is entered, the player operates the operation handle 24 to rotate the operation handle 24 to make a pachinko ball by the ball hitting device 23. “Right-handed” is performed in which a pachinko ball is launched toward the second path 33b. The pachinko ball launched into the second path 33b during the right strike rolls along the right flange 41c of the frame-shaped decorative body 41. When the pachinko ball flowing down the second path 33b wins the second ordinary winning port 50a of the second ordinary winning device 50, the pachinko ball is guided by the flange portion 50b as shown in FIG. It passes through a second ball passage 75 formed in the second ball passage member 76 and is discharged out of the machine from the outlet 76b. When the pachinko ball flowing through the first vertical passage portion 75a in the second sphere passage 75 is detected by the second ordinary sphere detection sensor 77, the detection signal is transmitted to the main control device 31, and the main control device 31 Then, a control signal is output to the payout control device 29 to cause the ball payout device 28 to pay out a predetermined number of prize balls.

  As shown in FIG. 16, the pachinko ball that has won the special winning opening 47a during the big hit game in which the big hit has occurred is guided rearward by a guide passage 65 provided in the device main body 47c of the special winning device 47, and the ball outlet 65a. Is sent from. The pachinko balls fall toward the receiving port 76c formed in the second ball passage member 76, pass through the second vertical passage portion 75c, and are discharged from the outlet 76b to the outside of the machine. In other words, the pachinko ball that has won the special prize opening 47a is received and discharged into the second ball passage 75 for discharging the pachinko ball that has won the second normal prize opening 50a. There is no need to provide a dedicated ball passage for discharging the ball, and the installation space for providing the ball passage on the back side of the game board can be reduced.

  Here, a number of components such as a start winning device 46, a special winning device 47, a normal winning device 50, and a ball passing gate 48 are arranged in an area on the right side (second path 33b) of the game board 12 in the width direction. In the pachinko machine 10 configured to perform “right-handed”, a large number of parts are arranged in a narrow space, so that the degree of freedom in design is low. However, in the embodiment, since the ball passage for discharging the pachinko balls won in the plurality of winning openings 47a, 50a is used as one, the number of the ball passages is reduced. Even in the case where these parts are arranged in an uneven manner, the degree of freedom in design can be improved without pressing the installation space for the parts.

  The pachinko ball that has won the special winning opening 47 a is detected by the special ball detection sensor 64, and when the detection signal is transmitted to the main control device 31, the main control device 31 sends the payout control device 29 the payout control device 29. A control signal is output to cause the ball payout device 28 to pay out a predetermined number of prize balls. The special ball detection sensor 64 is configured to detect a pachinko ball before passing through the receiving port 76c. Further, as shown in FIG. 17, the second ordinary sphere detection sensor 77 for detecting the pachinko ball won in the second ordinary winning opening 50a is a first vertical passage portion upstream of the receiving port 76c in the second sphere passage 75. 75a. That is, even if there is a single ball path for discharging the pachinko balls won in the special winning opening 47a and the second normal winning opening 50a, it is possible to individually detect the pachinko balls won in the winning openings 47a and 50a. It is possible to respond differently to each of the winning openings 50a and 47a, such as changing the number of prize balls.

  As shown in FIG. 17, the second ball passage member 76 of the embodiment has a branch passage for communicating with the ball outlet 65a only by forming an opening 76c opposite to the ball outlet 65a of the special winning device 47. Since the second spherical passage member 76 is not separately formed, the shape of the second spherical passage member 76 is not complicated, and molding is easy. In addition, since the opening dimension of the receiving port 76c facing downward with respect to the ball outlet 65a of the special winning device 47 is set larger than the ball outlet 65a, the pachinko ball passing through the ball outlet 65a and falling is received. The mouth 76c can be reliably received. Further, as shown in FIG. 16, the inner surface of the front wall that defines the receiving port 76c is formed as an inclined guide surface 76d that is displaced rearward from the front side toward the rear side, so that it has entered the receiving port 76c. The pachinko balls are smoothly guided toward the communicating portion with the second vertical passage portion 75c by the inclined guide surface 76d without stagnation.

  When the pachinko sphere flowing down the second path 33 b passes through the sphere passage gate 48, it is detected by the gate sphere detection sensor 66 of the gate 48. In response to the ball detection by the gate ball detection sensor 66, the main control device 31 performs a start port opening lottery for determining whether or not to open the second start port 46 a in the second start winning device 46. When the result of the open lottery is a win, the second start winning device 46 is driven and controlled to open the second start port 46a.

  When the pachinko ball wins the second start port 46a while the second start port 46a is open, and the pachinko ball is detected by the second start ball detection sensor 62, the main controller 31 A jackpot lottery is performed to determine whether or not to generate a jackpot. The pachinko ball that won the second starting port 46a during the big hit game is stored as a holding ball, and after the big hit game, the big hit lottery is performed based on the held ball, and the first starting ball detection sensor 53 detects the pachinko ball. As in the case of detection, the main control device 31 starts the symbol variation effect on the symbol display device 15. Further, when receiving a detection signal from the second starting ball detection sensor 62, the main control device 31 outputs a control signal to the payout control device 29 to cause the ball payout device 28 to pay out a predetermined number of prize balls.

[About the fraud detection device 84]
Next, the operation of the fraud detection device 84 will be described. First, when the detection sensor unit 85 and the metal ball for detection 86 are assembled to the case body 51, the detection sensor unit 85 is accommodated and set in the sensor accommodating portion 89c of the base body 55, and the detection opening 87a is inserted into the detection port 87a. A metal ball 86 for detection is inserted. Then, the first support portions 90a and 90a of the cover body 56 are inserted into the sensor housing portion 89c, and the cover body 56 is screwed and fixed to the base body 55, whereby the detection sensor unit 85 and the detection sensor unit 85 are detected. The metal ball 86 is positioned and held inside the case body 51. The fraud detection device 84 accommodates the detection sensor unit 85 and the detection metal ball 86 in the case body 51 to which the first start ball detection sensor 53 is attached and can be handled integrally with the first start ball detection sensor 53. Therefore, the positional relationship between the two 53 and 85 can be properly maintained.

  As shown in FIG. 10, when the base body 55 and the cover body 56 are assembled, the detection sensor unit 85 has the rear wall 89b and the first support portion 90a in a state where movement on both sides in the left-right direction is restricted by the side walls 89a and 89a. , 90a, and is held from above and below by the restricting portions 89d, 89d and the support protrusion 90c. Thus, the detection sensor unit 85 is held on the sensor installation unit 61 without rattling. Further, since the ball receiving portion 89e and the second support portion 90b are in contact with the detection metal ball 86 set in the detection port 87a, the detection metal ball 86 is substantially in the opening direction in the detection port 87a. Held in the center position. That is, the detection metal sphere 86 can be accurately positioned within the induction magnetic field of the detection coil 88, and the detection sensor unit 85 can be reliably maintained in the oscillation non-detection state.

  By simply assembling the base body 55 and the cover body 56, an appropriate positional relationship between the detection sensor unit 85 and the detection metal ball 86 is defined, so that a careful work for securing the positional relationship between the two is not required. Assembling work can be made extremely efficient. Further, since a complicated structure for holding the detection sensor unit 85 and the detection metal ball 86 in an appropriate positional relationship is not required, the cost can be reduced. In addition, by adopting the spherical metal ball for detection 86, the metal ball 86 for detection may be positioned in the detection port 87a without considering the posture of the metal ball for detection 86, and the assembly of the metal ball for detection 86 becomes easy. . Thus, in this embodiment, the same detection sensor D as that of the existing detection sensor D is adopted as the detection sensor unit 85, and the detection sensor unit 85 is maintained in the oscillation non-detection state by the pachinko sphere as the detection metal sphere 86. It was. Accordingly, it is not necessary to newly develop and manufacture the detection sensor unit 85 and the metal ball for detection 86, and the cost can be reduced.

  With the case body 51 positioned and fixed to the case installation portion 72 of the installation member 14 via a plurality of attachment columns 72 a, the installation member 14 is attached to the back surface of the game board 12. In this state, the detection sensor unit 85 is positioned in the vicinity of the first and second start winning devices 44 and 46 and the special winning device 47 in the lower rear of the game board 12 (see FIG. 4). Since the detection sensor unit 85 is inclined backward from the upper side to the lower side, the opening direction of the detection port 87a of the detection sensor unit 85 is a direction inclined downward from the rear side to the front side. . Therefore, as shown in FIG. 8, the radio waves emitted from the lower front side of the game board 12 toward the first and second start winning devices 44 and 46 and the special winning device 47 can be easily captured, and the illegal radio wave action can be reliably ensured. Can be detected. Moreover, the fraud detection device 84 also serves as the case body 51 on which the first start ball detection sensor 53 of the first start winning device 44 is provided as a case body to which the detection sensor unit 85 and the detection metal ball 86 are attached. Therefore, the positional relationship between the detection sensor unit 85 and the first starting ball detection sensor 53 is properly maintained, and an illegal act with respect to the first starting ball detection sensor 53 can be reliably detected.

  The detection sensor unit 85 accommodated in the case body 51 is substantially hidden by the game board 12 and the start opening 45 and is difficult to see from the front side. You can avoid being aware of this. In addition, since it is difficult to determine the installation location of the detection sensor unit 85, it is possible to suppress the act of avoiding the detection of unauthorized radio wave action by radiating radio waves so as to avoid the detection range of the detection sensor unit 85.

[Effects of cheating]
Next, an operation when an illegal radio wave action is performed will be described. It should be noted that the fraud detection device 84 maintains the detection sensor unit 85 in an oscillation non-detection state by the metal ball for detection 86 and outputs a low level signal from the output circuit H when the fraudulent radio wave action is not performed normally. Has been. Accordingly, as shown in FIG. 22, the low level signal is continuously input to the main control device 31 at the normal time. When an illegal radio wave action occurs, as shown in FIG. 23, the transmission detection circuit G erroneously detects intermittent oscillation due to the radio wave, and the output circuit H repeatedly outputs a low level signal and a high level signal alternately. Then, main controller 31 determines that an illegal radio wave action has occurred when the signal from output circuit H is switched from the low level signal to the high level signal. That is, according to the fraud detection device 84 of the embodiment, the detection sensor unit 85 is changed from the oscillation non-detection state to the oscillation detection state by the radio wave, so that the illegal radio wave action can be detected very easily with a simple structure. In the embodiment, since the output from the output circuit H is switched from the low level signal to the high level signal, the main controller 31 determines the occurrence of the illegal radio wave action. Can be detected. Therefore, the control burden on the main controller 31 can be reduced, and the possibility of erroneous determination is reduced. Further, since the same sensor as the existing detection sensor D can be adopted as the detection sensor unit 85 without separately forming a circuit for detecting radio waves in the detection sensor unit 85, the manufacturing cost of the fraud detection device 84 can be reduced. can do.

  When determining the occurrence of the illegal radio wave action, the main control device 31 outputs a control signal to the overall control device 19 to notify the symbol display device 15, the lamp device 18 and the speaker 22 of the occurrence of the illegal radio wave action. That is, as shown in FIG. 25, the symbol display device 15 displays a message indicating that the illegal radio wave action has occurred on the display unit 15a, and the speaker 22 outputs a sound indicating that the illegal radio wave action has occurred. Further, the lamp device 18 causes the illuminant to emit light in the first color to notify an employee of the game hall of the occurrence of illegal radio wave action. As described above, when an illegal radio wave action occurs, the symbol display device 15 or the like immediately reports the occurrence of the fraud, so that the fraud can be promptly notified to employees in the game hall. In addition, the symbol display device 15 and the speaker 22 are informed of the occurrence of the illegal radio wave action, and the lamp device 18 emits light in the first color corresponding to the illegal radio wave action. It is possible to easily determine which fraud has occurred and respond quickly.

  Further, the main controller 31 outputs a security signal to the hall computer 92 via the external terminal board 91. Upon receiving the security signal, the hall computer 92 displays on the display that some sort of fraud has occurred and notifies the administrator of the management room or the like. Thus, when it is determined that an illegal radio wave action has occurred, not only the pachinko machine 10 but also the hall computer 92 is notified, so even if an employee of the amusement hall does not notice the occurrence of the fraud, It is possible to notify the manager of the management room about the occurrence of fraud. Since the same security signal is input to the hall computer 92, the display content on the display is the same regardless of any fraudulent act (illegal radio wave act or fraudulent magnetic act). However, as described above, the symbol display device 15, the lamp device 18, and the speaker 22 are notified of the unauthorized radio wave action, so that employees can recognize that the illegal radio wave action has occurred.

  Next, when the disconnection action is performed, no signal is input from the output circuit H to the main controller 31 as shown in FIG. When there is no input from output circuit H, main controller 31 determines that a disconnection action has occurred, and performs the same response as in the case of the unauthorized radio wave action described above. That is, the fact that an illegal radio wave action has occurred is displayed on the display unit 15a of the symbol display device 15, and the speaker 22 outputs a sound that an illegal radio wave action has occurred. In addition, the lamp device 18 is caused to emit light in the first color to notify an employee of the game hall of the occurrence of illegal radio wave action. Further, the main control device 31 outputs a security signal to the hall computer 92 to display on the display of the hall computer 92 that some sort of fraud has occurred. As described above, in the embodiment, even when a disconnection action is performed, the action can be detected. Therefore, it is possible to prevent the fraud detection device 84 from being invalidated by cutting the wiring of the detection sensor unit 85. .

  Further, when the ball removal action is performed, the oscillation circuit F starts oscillating by removing the detection metal ball 86 from the detection port 87a. Therefore, the oscillation detection circuit G detects oscillation, and the detection sensor unit 85 changes to the oscillation detection state. Thereby, as shown in FIG. 22, the output signal of the output circuit H is switched from the low level signal to the high level signal. Therefore, the main control device 31 determines that the ball removal action has occurred when the signal input from the output circuit H is switched from the low level signal to the high level signal. The same action is taken to report the occurrence of fraud. Thus, in this embodiment, even when a ball removal action is performed, the fraudulent action can be detected, so that the fraud detection device 84 is invalidated by removing the detection metal ball 86 from the detection port 87a. Can be prevented.

  When an illegal magnetic action is performed, the first magnetic sensor 79 or the second magnetic sensor 81 detects magnetism such as a magnet and outputs a detection signal to the main control device 31. When a detection signal is input from the first magnetic sensor 79 or the second magnetic sensor 81, the main controller 31 determines that an illegal magnetic action has occurred, and notifies the symbol display device 15 or the like of the illegal action. That is, the main control device 31 outputs a control signal to the overall control device 19 to notify the symbol display device 15, the lamp device 18 and the speaker 22 of the occurrence of an illegal magnetic action. Specifically, as shown in FIG. 25, the display unit 15a of the symbol display device 15 displays a message indicating that an illegal magnetic action has occurred, and causes the speaker 22 to output a sound indicating that the illegal magnetic action has occurred. Further, the lamp device 18 causes the light emitter to emit light in the second color to notify the employee of the game hall of the occurrence of the illegal magnetic action. As described above, even when an illegal magnetic act occurs, the occurrence of the illegal act can be immediately notified to an employee or the like. Moreover, since it can be determined from the output contents of the symbol display device 15 and the speaker 22 and the emission color of the lamp device 18 that the illegal magnetic action has occurred, the employees can quickly respond to the illegal magnetic action. . The main controller 31 also outputs a security signal to the hall computer 92 even when an illegal magnetic action occurs. Accordingly, the fact that some sort of fraud has occurred is displayed on the display of the hall computer 92, and the administrator of the management room can know the occurrence of the fraud.
