[About illegal acts by radio waves]
Here, the two starting ball detection sensors 36 and 37 and the special ball detection sensor 39 described above are so-called inductive proximity switches, and in the pachinko machine 10 of the embodiment, both are the same sensors (hereinafter these sensors 36). , 37, 39 may be simply referred to as a sphere detection sensor D). As shown in FIG. 21 (a), the sphere detection sensor D has a basic configuration including a sensor main body 123 having an oscillation circuit and the like, and a sphere passage port 124 provided with a coil through which a pachinko sphere can pass. As shown in FIG. 21 (b), in the state where the ball detection sensor D is not detecting the pachinko ball (the state where the pachinko ball has not passed through the ball passage opening 124), the oscillation circuit oscillates and the high level 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 124), the oscillation of the oscillation circuit stops or attenuates, and a low-level signal (hereinafter referred to as a low level signal). Is called a low level signal). The main control device 31 counts the pachinko ball by 1 when the output signal from the ball detection sensor D is switched from the high level signal to the low level signal, and controls the payout control device 29 to control the ball payout device. 28 causes the award ball to be paid out.

  However, an illegal act (hereinafter referred to as an illegal radio wave action) may be performed in which a radio wave is radiated to the sphere detection sensor D to forcibly change the output signal of the sphere detection sensor D. In general, as shown in FIG. 20, this fraudulent radio wave act is a game board in which a fraudster conceals a radio wave generator E obliquely below the game board 12, and a start winning device 35, a special prize winning device 38, etc. are provided. This is performed by radiating radio waves from the radio wave generator E toward the lower center of 12. When the sphere detection sensor D receives the radio wave radiated from the radio wave generator E while the pachinko sphere passes through the sphere passage 124, the sphere detection sensor D erroneously detects that there is intermittent oscillation. End up. As a result, as shown in FIG. 21B, the sphere detection sensor D repeatedly outputs a low level signal and a high level signal, and the main controller 31 switches each time the high level signal is switched to the low level signal. Pachinko balls will be counted. The main control device 31 counts a plurality of prize balls and pays out a lot of prize balls or draws a big hit lottery even though one pachinko ball has passed through the ball passage opening 124. There is a risk of it. Therefore, in the pachinko machine 10 of the embodiment, the fraud detection device 125 is installed in the sensor installation unit 118 in order to detect such an illegal radio wave action.

[Unauthorized Device]
As shown in FIGS. 22 and 23, the fraud detection device 125 includes a detection sensor unit (state change means) 126, a detection metal ball (state maintenance means, magnetic body, metal ball, game ball) 127, and these It is basically composed of a detection sensor unit 126 and a case body 128 that houses a metal ball for detection 127. The detection sensor unit 126 basically includes a rectangular sensor device main body 129 and a cylindrical detection port 130 in which a through hole is defined. In the embodiment, the above-described start winning device 35 and the special winning award are used. The same ball detection sensor D provided in the device 38 or the like is employed. The diameter of the opening circle of the detection port 130 is set to be slightly larger than the diameter of the detection metal ball 127 (see FIG. 24A). A detection coil 131 is wound around the detection opening 130 along the opening edge, and the detection coil 131 generates a magnetic field around the detection opening 130. As shown in FIG. 25, the sensor device main body 129 is formed with an oscillation circuit F, an oscillation detection circuit G, and an output circuit H. As shown in FIG. 26 (a), the oscillation circuit F oscillates at a high frequency (for example, 1 MHz) in a state where no magnetic substance (detection metal sphere 127) exists in the magnetic field of the detection port 130. ing. As shown in FIG. 26B, when a magnetic body (detection metal sphere 127) is present in the magnetic field of the detection port 130, the oscillation circuit F stops or attenuates oscillation. The oscillation circuit F according to the embodiment is set to stop oscillation in a state where a magnetic body (detection metal ball 127) is present in the detection port 130.

  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. 26 (a), when detecting the oscillation of the oscillation circuit F, the oscillation detection circuit G 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 126 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. 26B, the low level signal has a value slightly larger than zero. The output circuit H is electrically connected to the main control device 31 via the first relay board 70 as will be described later. The high level signal and the low level signal output from the output circuit H are the main control device. 31. The metal ball for detection 127 stops the oscillation of the oscillation circuit F and maintains the detection sensor unit 126 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 127. As will be described later, the detection metal ball 127 is accommodated in the case body 128 in a state of being located in the detection port 130.

  That is, in the fraud detection device 125 of the embodiment, the oscillation of the oscillation circuit F is stopped by the metal ball for detection 127 at the normal time when the illegal radio wave action is not performed, and the detection sensor unit 126 is in an oscillation non-detection state. Maintained. Accordingly, as shown in FIG. 27, the oscillation detection circuit G outputs an oscillation stop detection signal, and a low level signal is output from the output circuit H. Therefore, a low level signal is always input to the main controller 31. Is done. On the other hand, when the detection sensor unit 126 is in the oscillation non-detection state, when radio waves are radiated from the radio wave generator E to the detection sensor unit 126, 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. 27, 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 125 according to the embodiment, the detection range of the radio wave in the detection sensor unit 126 is large on the opening direction side of the detection port 130 (vertical direction in FIG. 29) as shown in FIG. That is, the detection sensor unit 126 is configured to easily react to radio waves radiated from the opening direction of the detection port 130.

Part) 138 is formed. The first restricting portion 138 protrudes rearward from the rear surface of the first case base 134. When the detection sensor unit 126 is accommodated in the first half 132, as shown in FIG. The restricting portion 138 is positioned in contact with the detection sensor unit 126. A pair of guide ribs 139 and 139 extending in the front-rear direction are formed on the left and right first outer wall portions 135 and 135, respectively (the left guide ribs 139 and 139 are shown in FIGS. 23 and 24B). ). The pair of guide ribs 139, 139 extend in parallel with each other with a predetermined distance therebetween. The left and right first outer wall portions 135 and 135 are respectively formed with locking step portions 140 extending vertically between the pair of guide ribs 139 and 139 (see FIG. 22 for the right locking step portion 140. The portion of each first outer wall portion 135 on the front side of the locking step portion 140 is recessed inward (opposite the first outer wall portion 135 side). Further, a first wiring cutout 141 is formed at the lower portion of the right first outer wall 135 by cutting out the rear edge of the first outer wall 135.

  As shown in FIGS. 22 and 23, the second half body 133 includes a substantially rectangular second case base (case base) 142 and a second outer wall extending forward from the peripheral portion of the second case base 142. It is comprised from the part (wall part) 143, and is formed in the box shape open | released ahead. The opening shape opened to the front side of the second half 133 is substantially the same as the opening shape opened to the rear side of the first half 132. The second case base 142 is inclined rearward from the upper side to the lower side, and with the case body 128 attached to the sensor installation portion 118, a predetermined angle (about 60 in the embodiment) with respect to the board surface of the game board 12. °) configured to tilt (see FIG. 20). That is, as shown in FIG. 24A, the first case base 134 and the second case base 142 extend in parallel with each other in a state where the first half 132 and the second half 133 are assembled. ing.

  As shown in FIG. 22, the left and right second outer wall portions 143 and 143 are respectively formed with elastically deformable thin plate-like elastic locking pieces 144 and 144 extending forward. The distance between the two elastic locking pieces 144 and 144 is set to be slightly larger than the left and right width dimension of the first half 132 (the distance between the left and right first outer wall portions 135 and 135). Also, as shown in FIG. 24B, the vertical dimension of each elastic locking piece 144 is set slightly smaller than the distance between the pair of guide ribs 139, 139. As shown in FIG. 22, a case locking portion 145 is formed at the front end of each elastic locking piece 144 so as to protrude inward (opposing elastic locking piece 144). The spacing between the case locking portions 145 and 145 is set slightly smaller than the left and right width dimensions of the first half 132 (the spacing between the left and right first outer wall portions 135 and 135). Then, each elastic locking piece 144 is inserted between the pair of guide ribs 139, 139 while being elastically deformed, and each case locking portion 145 is locked to the corresponding locking step portion 140, whereby the first half body 132 and the second half 133 are detachably assembled (see FIG. 24B). In a state in which the first half 132 and the second half 133 are assembled, the rear end portion of the first outer wall portion 135 of the first half body 132 is connected to the front end portion of the second outer wall portion 143 of the second half body 133. A space is formed between the first half 132 and the second half 133 so as to accommodate the detection sensor unit 126 and the metal ball 127 for detection.

As shown in FIG. 22, on the front surface of the second case base 142, a plurality of (two in the embodiment) second restricting portions (regulations) extending across the left and right width directions of the second case base 142. Part) 146 is formed so as to protrude forward, and in a state in which the detection sensor unit 126 is accommodated in the second half 133, the second restricting part 146 comes into contact with the detection sensor unit 126 to be positioned. Yes. That is, as shown in FIG. 24A, in the state where the first half 132 and the second half 133 are assembled, the detection sensor unit 126 is sandwiched between the first restricting portion 138 and the second restricting portion 146, The detection sensor unit 126 is held in a posture parallel to the first case base 134 and the second case base 142. Further, the separation distance m ₂ from the front surface of the second case base 142 of the second restriction portion 146 is set to be substantially the same as the separation distance m ₁ from the rear surface of the first case base 134 in the first restriction portion 138. . Accordingly, the detection sensor unit 126 is held at a substantially central position in the separating direction of the first case base 134 and the second case base 142 (the opening direction of the detection port 130). Further, in the state where the first half 132 and the second half 133 are assembled, the separation distance l between the first case base 134 and the second case base 142 is substantially equal to the diameter dimension of the metal ball 127 for detection. Is set. Therefore, the detection metal ball 127 located in the detection port 130 is sandwiched between the first case base 134 and the second case base 142 and is held in the case body 128 without rattling. In a state where the detection metal sphere 127 is housed in the case body 128, the center of the detection metal sphere 127 is positioned so as to substantially coincide with the central portion of the detection port 130 in the opening direction.

  As shown in FIG. 22, a second wiring cutout 147 is formed at the lower portion of the second outer wall 143 on the right side by cutting out the front edge of the second outer wall 143. The second wiring cutout portion 147 is aligned with the first wiring cutout portion 141 in a state where the first half body 132 and the second half body 133 are assembled, and defines one wiring insertion hole 148. (See FIG. 24 (a)). The wiring insertion hole 148 is configured such that the wiring 126X of the detection sensor unit 126 housed in the case body 128 is inserted and drawn out of the case body 128. As shown in FIG. 15, when the fraud detection device 125 is attached to the sensor installation portion 118, the lower side of the case body 128 protrudes downward from the installation lower plate portion 121 via the installation recess 122, and the wiring insertion hole 148. Is exposed to the outside of the sensor installation portion 118. The wiring 126X of the detection sensor unit 126 drawn out through the wiring insertion hole 148 is connected to the first relay board 70.

  As shown in FIG. 15, in a state where the fraud detection device 125 is attached to the sensor installation unit 118, the fraud detection device 125 is located on the left side of the device space 50a of the bowl-shaped storage unit 50 (in FIG. ). Accordingly, the fraud detection device 125 is positioned in the vicinity of the start winning device 35 and the special winning device 38 at the lower rear of the game board 12 (see FIGS. 4 and 20). Further, since the sensor installation unit 118 is provided on the rear side of the installation member 14, the fraud detection device 125 is hidden by the installation member 14 and cannot be seen from the front side of the game board 12. Moreover, since the detection sensor unit 126 is housed in the case body 128 in a posture inclined backward from the top to the bottom, as shown in FIG. 20, the opening direction of the detection port 130 is from the rear to the front. It becomes the direction which inclines below toward. In other words, by directing the opening direction of the detection port 130 toward the front lower side of the game board 12, it is possible to easily catch illegal radio waves radiated from the radio wave generator E set at the front lower side of the game board 12. In addition, in a state where the fraud detection device 125 is attached to the sensor installation unit 118, most of the case body 128 is accommodated in the sensor installation space 117 so that the rear part of the case body 128 does not protrude from the rear part of the installation member 14. It has become. In the state where the third relay board 72 is attached to the third relay board holding portion 69, the sensor installation space 117 is closed by the third relay board 72, and as shown in FIG. The lower part of the case body 128 is left and covered with the third relay board 72.

[Unauthorized judgment of main controller]
As described above, the main control device 31 receives a low level signal from the fraud detection device 125 during normal operation (oscillation non-detection state) (see FIG. 27). Further, when the detection unit is changed to an oscillation detection state due to an illegal radio wave action, a high level signal is input from the output circuit H. The main control device 31 determines that an illegal radio wave action has occurred when the signal from the fraud detection device 125 is switched from a low level signal to a high level signal (see FIG. 27). That is, when the detection sensor unit 126, which is maintained in the oscillation non-detection state by the metal balls for detection 127, is changed to the oscillation detection state, the main control device 31 detects an illegal radio wave action.

  Here, if the wiring 126X led out from the detection sensor unit 126 is cut or pulled out from the detection sensor unit 126 by an unauthorized person (hereinafter referred to as disconnection action), as shown in FIG. No signal is output (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 127 from the detection unit (hereinafter referred to as a ball removal act), the oscillation circuit F resumes oscillation and the detection sensor unit 126 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 83 and 102, 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 control device 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 apparatus 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 liquid crystal display device 15, the lamp device 18, and the speaker 22 of the occurrence of an illegal act. Here, as shown in FIG. 30, in the pachinko machine 10 according to the embodiment, the liquid crystal display device 15, the lamp device 18, and the speaker 22 are subjected to an illegal radio wave action (including a disconnection action and a ball pulling action) and an illegal magnetic action. 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 liquid crystal display device 15 displays that the illegal radio wave action has occurred, and causes the speaker 22 to output a sound 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 action occurs, the display unit 15a of the liquid crystal display device 15 displays that the 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 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. 8, the main control device 31 is electrically connected to a hall computer (notification means) 149 installed in a game room management room or the like via an external terminal board 150 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 149 when detecting the illegal radio wave action and the illegal magnetic action. In the embodiment, the same security signal is output in both cases of an illegal radio wave action and an illegal magnetic action. When the security signal is input to the hall computer 149, the occurrence of fraud is displayed on a display (not shown) of the hall computer 149 so that the 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 149, so the display content on the display is the same. However, since the operation modes of the liquid crystal 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 above-described embodiment will be described below.

[About the first and second anti-fraud members]
First, the operation of the first and second fraud prevention members 84 and 103 will be described. When the first and second ball passage members 53 and 54 are attached to the first and second ball passage fixing portions 51 and 52, the first ball passage member 53 is fixed to the fixing bosses 57 a and 57 a of the first projecting surface portion 57. The boss receiving portions 53a and 53a of the second ball passage member 54 are screwed to the fixed bosses 58a and 58a of the second projecting surface portion 58. Thereby, as shown in FIG. 5, the first and second ball passage members 53 and 54 are attached to the first and second ball passage fixing portions 51 and 52. At this time, as shown in FIG. 10, the first ordinary sphere detection sensor 63 installed in the first sensor mounting portion 61 of the first sphere passage member 53 is inserted through the first sensor insertion hole 62 of the first protruding surface portion 57. And faces the upper stage 79 in the first accommodation space 55. Similarly, as shown in FIG. 11, the second ordinary sphere detection sensor 66 installed in the second sensor mounting portion 64 of the second sphere passage member 54 is inserted through the second sensor insertion hole 65 of the second projecting surface portion 58. Facing the second storage space 56. Here, since the first and second ball passage fixing portions 51 and 52 are formed so as to protrude forward from the facing surface portion 42 of the installation member 14, as shown in FIG. 5, the first and second ball passage fixing portions 51 and 52 are formed. The members 53 and 54 face the opening front end side of the installation member 14. Further, the fixing bosses 57a, 57a, 58a, 58a for fixing the first and second ball passage members 53, 54 are provided on the first and second projecting surface portions 57, 58 located in front of the facing surface portion 42. Yes. Therefore, as compared with the case where the fixed bosses 57a, 57a, 58a, and 58a are directly provided on the facing surface portion 42, the fixed bosses 57a, 57a, 58a, and 58a are as much as the first and second protruding surface portions 57 and 58 protrude forward. The front and rear dimensions of the can be shortened. Therefore, the strength of the fixed bosses 57a, 57a, 58a, 58a is improved, and the first and second ball passage members 53, 54 can be stably attached to the installation member 14.

  Next, the first and second magnetic sensors 83 and 102 are attached to the first and second accommodation spaces 55 and 56, respectively. That is, the first magnetic sensor 83 is inserted into the first accommodating space 55 through the first opening 73, and the first magnetic sensor 83 is inserted into the holding body 82 a of the first sensor holding portion 82. And the 1st magnetic sensor 83 is attached to the 1st sensor holding part 82 because the holding hook 82b of the 1st sensor holding part 82 latches to the 1st magnetic sensor 83 (refer to Drawing 12 (a)). Similarly, the second magnetic sensor 102 is inserted into the second housing space 56 through the second opening 93, and the second magnetic sensor 102 is inserted into the holding body 101 a of the second sensor holding portion 101. And the 2nd magnetic sensor 102 is attached to the 2nd sensor holding part 101 because the holding hook 101b of the 2nd sensor holding part 101 latches to the 2nd magnetic sensor 102 (refer FIG.12 (b)). At this time, since the first and second storage spaces 55 and 56 are expanded from the front to the rear, the first and second magnetic sensors 83 and 102 are replaced with the first and second sensor holding portions 82 and 101. Can be easily attached to.

  Next, when the first fraud prevention member 84 is disposed in the first accommodation space 55, the front side of the first side wall portion 86 is inserted into the first opening 73, and the first fraud prevention member 84 is accommodated in the first accommodation space 55. It can be pushed into the space 55. At this time, as shown in FIG. 10, the first inner side surface 78 of the first accommodation space 55 is formed so as to expand from the front to the rear, so the opening dimension of the first opening 73 is set to the front side ( The first projecting surface portion 57) can be larger. Therefore, the 1st fraud prevention member 84 can be easily inserted in the 1st accommodating space 55, and workability | operativity can be improved.

  When the first fraud prevention member 84 is further inserted and the front end of the first side wall portion 86 abuts on the connecting wall 81 in the first accommodating space 55 as shown in FIG. It is completely inserted into the first accommodation space 55. At this time, the first protrusions 91 of the first side wall portions 86 come into contact with the corresponding first inner side surfaces 78, and the first pressing portions 89 are elastically deformed. That is, the first protrusion 91 presses the first side wall portion 86 by the elastic force of the first pressing portion 89, and the first fraud prevention member 84 is disposed in the first accommodation space 55 with a predetermined locking force. As a result, it is possible to prevent the first fraud prevention member 84 from slipping out of the first accommodation space 55 or falling off with a slight impact. Moreover, since the first tamper-proof member 84 is held in the first housing space 55 by the first pressing portion 89, there is no need to fix the first tamper-proof member 84 with a fixing member or the like, and the first tamper-proof member 84 can be easily attached. Further, the first fraud prevention member 84 has a shape in which the first side wall portion 86 expands from the rear to the front, and has a relationship opposite to the configuration of the first accommodation space 55. Therefore, the first protrusion 91 on the front side of the first side wall portion 86 can reliably contact the first inner surface 78 and the first fraud prevention member 84 can be securely held in the first accommodation space 55.

  As shown in FIG. 10, when the first fraud prevention member 84 is inserted into the first accommodation space 55, the first magnetic sensor 83 and the first sensor holding portion 82 face the first escape portion 92. The side wall portion 86a is prevented from interfering with the first magnetic sensor 83 and the first sensor holding portion 82. As shown in FIG. 14, the wiring 83 </ b> X led out from the first magnetic sensor 83 is pulled out to the rear of the first accommodation space 55 through the first wiring port 87 of the first base portion 85. Then, the wiring 83X of the first magnetic sensor 83 drawn out from the first accommodation space 55 is routed leftward through the first wiring through hole 77 of the first relay board holding portion 67.

  Here, as shown in FIG. 14, in a state where the first fraud prevention member 84 is disposed in the first accommodation space 55, the first base 85 is located on the substantially same plane as the first opening 73, The first base 85 closes the first opening 73. Furthermore, as shown in FIGS. 10 and 16, the first side wall portion 86 faces the corresponding first inner side surface 78, and the rear side (lower step portion 80 side) space in the first accommodation space 55 is the first fraud prevention. Filled with member 84. That is, the first fraud prevention member 84 and the first inner side surface 78 are fitted into the first accommodating space 55 to such an extent that only a slight gap remains between the first inner side surface 78 and the first inner side surface 78. It is impossible to install the illegal part A between the two. Further, since the internal space of the first fraud prevention member 84 is divided into the first small space B by the first partition wall 88, the fraudulent part A may be installed in the internal space of the first fraud prevention member 84. Absent. Furthermore, by providing the first escape portion 92, the space on the front side of the first accommodation space 55 can be filled with the first fraud prevention member 84 without a substantial gap, so that the unauthorized parts A can be more effectively prevented from being installed. Can do. As shown in FIG. 10, since the first ordinary sphere detection sensor 63 is accommodated in the space on the front side (upper stage 79 side) of the first accommodation space 55, the first accommodation space is present due to the presence of the sensor 63. It is also impossible to install the unauthorized part A on the front side of 55.

  In addition, by disposing the first fraud prevention member 84 in the first accommodation space 55, the strength of the first ball passage fixing portion 51 as the fixing portion of the first ball passage member 53 can be improved. The ball passage member 53 can be stably fixed. Furthermore, since the inside of the first accommodation space 55 is filled with the first fraud prevention member 84, dust or the like hardly accumulates in the first accommodation space 55, and the first ordinary sphere detection sensor 63 and the first magnetic sensor 83 are prevented. It is possible to avoid the occurrence of problems and the like.

  When the second fraud prevention member 103 is disposed in the second accommodation space 56, the front side of the second side wall portion 105 is inserted into the second opening 93, and the second fraud prevention member 103 is inserted into the second accommodation space 56. Can be pushed into. As shown in FIG. 11, also in the second accommodation space 56, the second inner side surface 99 is formed so as to expand from the front to the rear, so that the opening size of the second opening 93 is increased. The second tamper-proof member 103 can be easily inserted into the second storage space 56. Further, when the second tamper-proof member 103 is inserted, the second upper side wall portion 105a of the second tamper-proof member 103 slides on the extending portion 100 provided on the second upper inner surface 99a of the second accommodation space 56. At the same time, the second lower side wall portion 105b of the second fraud prevention member 103 slides on the extending portion 100 provided on the second lower inner side surface 99b of the second accommodation space 56. At this time, as shown in FIG. 11, since the edge portions 100a, 100a of the extending portions 100, 100 extend in parallel in the front-rear direction, the second upper inner surface 99a and the second lower inner surface 99b Is guided by the extending portions 100, 100, and the second fraud prevention member 103 can be smoothly inserted into the second accommodation space 56.

  When the second side wall portion 105 of the second fraud prevention member 103 contacts the second projecting surface portion 58, the second fraud prevention member 103 is completely inserted into the second accommodation space 56. At this time, as shown in FIG. 18, the second protrusions 110 of the second side wall portions 105 come into contact with the corresponding second inner side surfaces 99 and the second pressing portions 108 are elastically deformed. The second fraud prevention member 103 is disposed in the second accommodation space 56 with a predetermined locking force. Therefore, it is possible to prevent the second fraud prevention member 103 from easily falling out of the second accommodation space 56. Further, since it is not necessary to fix the second tamper-proof member 103 with other fixing means or the like, the second tamper-proof member 103 can be easily attached. In addition, since the second tamper-proof member 103 expands from the rear toward the front, the second protrusion 110 reliably contacts the second inner surface 99 and the second tamper-proof member 103 is the second. The housing space 56 is firmly held.

  As shown in FIG. 18, when the second fraud prevention member 103 is inserted into the second accommodation space 56, the second magnetic sensor 102 and the second sensor holding portion 101 face the second escape portion 111. The upper side wall part 105a and the second left side wall part 105c do not interfere with the second magnetic sensor 102 and the second sensor holding part 101. The wiring 102X led out from the second magnetic sensor 102 is pulled out to the rear of the second accommodation space 56 through the second wiring port 106 and upward from the second wiring through hole 98 of the second relay board holding portion 68. It is pulled out (see FIG. 14). As shown in FIG. 11, when the second fraud prevention member 103 is inserted into the second accommodation space 56, the rear portion of the second ordinary sphere detection sensor 66 is in the second small space of the second fraud prevention member 103. C.

  As shown in FIG. 14, in the state where the second fraud prevention member 103 is disposed in the second accommodation space 56, the second base 104 closes the second opening 93 and the second side wall 105 corresponds to the corresponding second. The second storage space 56 is filled with the second fraud prevention member 103 so as to face the inner surface 99. That is, the second tamper-proof member 103 and the second inner side surface are fitted into the second accommodation space 56 so that only a slight gap remains between the second inner side surface 99 and the second inner side surface 99. 99, it is impossible to install the illegal part A. Further, since the internal space of the second fraud prevention member 103 is divided by the second partition wall 107 into a second small space C having a size that makes it impossible to install the fraudulent part A, the second fraud prevention member 103 is divided. No unauthorized parts A are installed in the internal space. In addition, since the second escape space 111 is provided, the second accommodating space 56 can be filled with the second fraud prevention member 103 without a substantial gap, so that the installation of the fraudulent part A can be more effectively prevented. it can.

  In addition, by arranging the second fraud prevention member 103 in the second accommodation space 56, there is an advantage that the strength of the second ball passage fixing portion 52 is improved and the second ball passage member 54 can be stably fixed. is there. Further, by filling the second storage space 56 with the second fraud prevention member 103, dust or the like hardly accumulates in the second storage space 56, and the second ordinary sphere detection sensor 66 or the second magnetic sensor 102 has a problem. It is possible to suppress the occurrence of defects.

  The first and second pressing portions 89 and 108 are configured so that the first and second protrusions 91 and 110 are merely in contact with the first and second inner side surfaces 78 and 99. It can be easily detached from the first and second accommodation spaces 55 and 56 simply by pulling 84 and 103 rearward. In addition, the second fraud prevention member 103 is guided by the second upper wall portion 105a and the second lower wall portion 105b by the extending portions 100, 100 when being pulled out from the second accommodating space 56. The prevention member 103 can be removed from the second accommodation space 56 smoothly.

  When the first to third relay boards 70, 71, 72 are attached to the first to third relay board holders 67, 68, 69, respectively, as shown in FIG. The first and second relay boards 70 and 71 are respectively closed from behind, and cannot be seen from behind the installation member 14. However, since the first and second accommodation spaces 55 and 56 are filled with the first and second fraud prevention members 84 and 103, the unauthorized parts A are not installed in the spaces 55 and 56, and the It is possible to prevent the situation where fraud continues for a long time. As shown in FIG. 15, the wiring 83 </ b> X of the first magnetic sensor 83 drawn out from the first wiring through hole 77 is connected to the first relay substrate 70. That is, the wiring 83X of the first magnetic sensor 83 is configured to be connected to the first relay substrate 70 located immediately behind the first accommodation space 55, so that the distance for routing the wiring 83X is shortened and wiring work is performed. Can be easy. The wiring 102X of the second magnetic sensor 102 drawn out from the second wiring through hole 98 is routed to the right in FIG. 15 in the installation member 14 and connected to the first relay board 70.

[Unauthorized Device]
Next, the operation of the fraud detection device 125 will be described. First, when the fraud detection device 125 is assembled, the detection sensor unit 126 is set in the first half 132 and the metal ball 127 for detection is inserted into the detection port 130. Then, by inserting the elastic locking pieces 144, 144 of the second half 133 between the corresponding guide ribs 139, 139, and locking the case locking portions 145, 145 to the locking step portions 140, 140, The first half 132 and the second half 133 are assembled. As described above, the case body 128 can be easily assembled by simply locking the case locking portions 145 and 145 of the elastic locking pieces 144 and 144 to the locking step portions 140 and 140, and can be fixed with screws or the like. There is no need to use means. In addition, since the detection sensor unit 126 and the detection metal ball 127 are accommodated in the case body 128 and the fraud detection device 125 can be handled as one unit, the fraud detection device 125 can be easily handled.

  As shown in FIG. 24A, when the first half 132 and the second half 133 are assembled, the detection sensor unit 126 is sandwiched between the first restriction portion 138 and the second restriction portion 146, and the detection sensor unit 126. Is held in a posture parallel to the first case base 134 and the second case base 142. Thereby, the detection sensor unit 126 is held without rattling at a substantially central position in the separating direction of the first case base 134 and the second case base 142. Further, since the first case base 134 and the second case base 142 abut against the detection metal ball 127 set in the detection port 130, the detection metal ball 127 is arranged in the opening direction in the detection port 130. It is held at a substantially central position. That is, the detection metal sphere 127 can be accurately positioned within the induction magnetic field of the detection coil 131, and the detection sensor unit 126 can be reliably maintained in the oscillation non-detection state.

  By simply assembling the first half 132 and the second half 133, the appropriate positional relationship between the detection sensor unit 126 and the detection metal ball 127 is defined. The assembly work can be made extremely efficient without the necessity. Further, since a complicated structure for holding the detection sensor unit 126 and the metal ball for detection 127 in an appropriate positional relationship is not required, the cost can be reduced. In addition, by adopting the spherical metal ball for detection 127, it is sufficient to position the metal ball for detection 127 in the detection port 130 without considering the posture of the metal ball for detection 127, and the assembly of the metal ball for detection 127 becomes simple. . Thus, in this embodiment, the same detection sensor unit 126 as that of the existing detection sensor D is employed, and the detection sensor unit 126 is maintained in the oscillation non-detection state by the pachinko sphere as the detection metal sphere 127. It was. Therefore, it is not necessary to newly develop and manufacture the detection sensor unit 126 and the detection metal ball 127, and the cost can be reduced.

  Next, the fraud detection device 125 is attached to the sensor installation unit 118. That is, the lower side of the case body 128 faces the installation recess 122, and the fraud detection device 125 is inserted into the sensor installation space 117 so that the case body boss receivers 137 and 137 of the case body 128 are connected to the sensor of the sensor installation section 118. The bosses 120 and 120 are aligned with the rear end portions. The fraud detection device 125 is attached to the sensor installation unit 118 by screwing screws into the sensor bosses 120 and 120. At this time, as shown in FIG. 15, the lower side of the fraud detection device 125 protrudes downward from the sensor installation space 117 via the installation recess 122, and the wiring insertion hole 148 of the case body 128 is outside the sensor installation space 117. Come on. In this state, the wiring 126 </ b> X of the detection sensor unit 126 drawn out from the wiring insertion hole 148 is connected to the first relay board 70. Thus, since the fraud detection device 125 is provided on the rear side of the installation member 14, the wiring 125X can be easily connected to the first relay board 70, and the wiring work can be performed efficiently. As shown in FIG. 20, most of the fraud detection device 125 is accommodated in the sensor installation space 117 so that the rear part of the case body 128 is not bulky on the rear side of the installation member 14. In other words, it is possible to prevent the fraud detection device 125 from protruding from the rear part of the installation member 14 and disturbing the fraud detection device 125.

  When the fraud detection device 125 is attached to the sensor installation unit 118, the fraud detection device 125 is positioned in the vicinity of the start winning device 35 and the special winning device 38 at the lower rear of the game board 12 (see FIG. 4, see FIG. Since the case body 128 is inclined backward from the top to the bottom, the opening direction of the detection port 130 of the detection sensor unit 126 is a direction inclined downward from the rear to the front. Accordingly, as shown in FIG. 20, it is possible to easily detect radio waves radiated from the lower front side of the game board 12 toward the starting prize-winning device 35 and the special prize-winning device 38, and to reliably detect illegal radio wave actions. Become. Moreover, since the fraud detection device 125 is hidden by the installation member 14 and cannot be seen from the front side of the game board 12, it can be avoided that the fraudster is aware that the fraud countermeasure has been taken. Further, since the location where the fraud detection device 125 is installed cannot be determined, it is possible to suppress the act of avoiding the detection of the fraudulent radio wave action by emitting radio waves so as to avoid the detection range of the fraud detection device 125. .

[Effects of cheating]
Next, an operation when an illegal radio wave action is performed will be described. The fraud detection device 125 maintains the detection sensor unit 126 in an oscillation non-detection state by the metal ball for detection 127 and outputs a low level signal from the output circuit H when the fraudulent radio wave action is normal. Has been. Therefore, as shown in FIG. 27, the low level signal is continuously input to the main controller 31 in the normal state. When an illegal radio wave action occurs, as shown in FIG. 28, 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 125 of the embodiment, the detection sensor unit 126 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. In addition, since the same sensor as the existing detection sensor D can be adopted as the detection sensor unit 126 without separately forming a circuit for detecting radio waves in the detection sensor unit 126, the manufacturing cost of the fraud detection device 125 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 liquid crystal 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. 30, the liquid crystal display device 15 causes the display unit 15 a to display that an illegal radio wave action has occurred, and the speaker 22 outputs a sound indicating that an 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. In this manner, when an illegal radio wave action occurs, the liquid crystal display device 15 or the like immediately notifies the occurrence of the fraud, so that the fraud can be promptly notified to employees in the game hall. In addition, the liquid crystal 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 to respond quickly.

  Further, main controller 31 outputs a security signal to hall computer 149 via external terminal board 150. Upon receiving the security signal, the hall computer 149 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 149 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 149, 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, since the liquid crystal display device 15, the lamp device 18, and the speaker 22 are notified of the unauthorized radio wave action, employees and the like 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 the output circuit H, the main control device 31 determines that a disconnection action has occurred, and performs the same action 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 liquid crystal display device 15, and the speaker 22 outputs a sound indicating that the 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, main controller 31 outputs a security signal to hall computer 149 to display on the display of hall computer 149 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, so that the wiring 126X of the detection sensor unit 126 is cut to prevent the fraud detection device 125 from being invalidated. Can do.

  In addition, when the ball removal action is performed, the oscillation circuit F starts to oscillate when the detection metal ball 127 is removed from the detection port 130. Therefore, the oscillation detection circuit G detects oscillation, and the detection sensor unit 126 changes to an oscillation detection state. Thereby, as shown in FIG. 27, 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 125 is invalidated by removing the detection metal ball 127 from the detection port 130. Can be prevented.

  When an illegal magnetic action is performed, the first magnetic sensor 83 or the second magnetic sensor 102 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 83 or the second magnetic sensor 102, the main controller 31 determines that an illegal magnetic action has occurred, and notifies the liquid crystal 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 so that the liquid crystal display device 15, the lamp device 18 and the speaker 22 are notified of the occurrence of illegal radio wave action. Specifically, as shown in FIG. 30, the display unit 15 a of the liquid crystal display device 15 displays a message indicating that the 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. In addition, since it is possible to determine that an illegal magnetic action has occurred from the output contents of the liquid crystal display device 15 and the speaker 22 and the light emission color of the lamp device 18, employees and the like can quickly respond to the illegal magnetic action. . The main controller 31 also outputs a security signal to the hall computer 149 even when an illegal magnetic action occurs. Therefore, the fact that some sort of fraud has occurred is displayed on the display of the hall computer 149, and the administrator of the management room can know the occurrence of the fraud.

[Example of change]
The above-described embodiment can be variously modified as described below.
(1) In the embodiment, the main controller is configured to be electrically connected to the hall computer via an external terminal board. The security signal from the main control device is input to the hall computer via the external terminal board (see FIG. 8). However, for example, as shown in FIG. 31, the external terminal plate 151 is connected to the payout control device 29, and the main control device 31 moves through the third relay board 72, the payout control device 29, and the external terminal plate 151. The computer 149 may be electrically connected. In this case, the security signal output from the main control device 31 is input to the hall computer 149 via the third relay board 72 → the payout control device 29 → the external terminal board 151.
(2) In the embodiment, the main control device outputs the same security signal when any fraud occurs. However, the security signal output by the main control device may be changed for each fraud so that the display content on the hall computer is different for each fraud. In this way, if a security signal corresponding to the type of fraudulent action is output, an administrator or the like can easily determine whether an illegal radio wave action or an illegal magnetic action has occurred in the hall computer.
(3) In the embodiment, even when a disconnection action or a ball pulling action occurs, the liquid crystal display device or the like is notified in the same manner as when an illegal radio wave action occurs. However, when a disconnection action or a ball pulling action occurs, it may be notified in a different manner. For example, when a disconnection action occurs, the liquid crystal display device or the speaker is notified that the disconnection action has occurred, and the lamp device is caused to emit light in a third color (for example, red). In addition, when a ball removal action occurs, the liquid crystal display device or speaker displays that the ball removal action has occurred, and causes the lamp device to emit light in a fourth color (for example, white), etc. It may also be possible to discriminate between the ball and the ball removal action.
(4) In the embodiment, the output circuit outputs a high level signal in the oscillation detection state, and the output circuit outputs the low level signal in the oscillation non-detection state. When the high level signal is output, the main controller Is configured to determine the occurrence of illegal radio wave acts. However, the signal output from the output circuit may be any signal as long as it is two types of signals corresponding to the oscillation detection state and the oscillation non-detection state. For example, contrary to the embodiment, a low level signal may be output in the oscillation detection state and a high level signal may be output in the oscillation non-detection state. In this case, when a low level signal is input, the main controller determines that an illegal radio wave action has occurred.
(5) In the embodiment, the detection sensor unit (state maintaining means) is changed in state from the oscillation non-detection state (second state) to the oscillation detection state (first state) by radio waves. However, the state changing means is changed from the second state to the first state by magnetism, and the act of erroneously operating the upper starting ball detection sensor, the lower starting ball detection sensor, the special ball detection sensor, etc. is detected by magnetism. It may be made possible.
(6) In the embodiment, a metal ball for detection which is a pachinko sphere is adopted as the state maintaining means. However, the state maintaining means may be any magnetic body that can stop or attenuate the oscillation of the oscillation circuit. May be. For example, a prismatic or cylindrical metal body can be employed as the state maintaining means.
(7) Although the fraud detection device is provided on the installation member in the embodiment, it may be provided on the back side of the game board. In addition, a plurality of fraud detection devices may be installed in the gaming machine.
(8) In the embodiment, two accommodation spaces are provided on the left and right, but one accommodation space may be provided, or three or more accommodation spaces may be provided.
(9) In the embodiment, the fraud prevention member has a box shape that opens forward, but the front side may be closed. Further, the inside of the fraud prevention member may be solid.
