(Characteristic part)
As shown in FIGS. 3 and 4, the specific sensor 21 uses a contactless magnetic detection sensor, the control board case 101 is illegally removed from the game board 4, and the position of the control board case 101 is predetermined. When displaced from the position, as described later, at least one end of the first electric wire 31 for transmitting a signal from the specific sensor 21 is connected so as to be easily detached from the specific sensor 21, and further, the main control board 100, the sub-control It is fixed to the game board 4 so as to be located in front of the board 200 and the relay board 500 (right side in FIGS. 3 and 4).
Preferably, the specific sensor 21 is disposed in a recess 4 a provided on the back surface of the game board 4, and the main control board 100 is disposed immediately behind the specific sensor 21.

  The signal output from the specific sensor 21 connects the first electric wire 31 (the electric wire connecting the specific sensor 21 and the relay board 500), the relay board 500, and the second electric wire 32 (the relay board 500 and the main control board 100). To the main control board 100 via the electric wire. In addition, the 1st electric wire 31 and the 2nd electric wire 32 are corresponded to the specific electric wire of this invention.

  The first electric wire 31 is fixed to a fixing portion 101 a provided on the back side of the control board case 101 so that the first electric wire 31 does not move in the length direction of the electric wire, and one end is specified by the first connector 41. The other end of the sensor 21 is connected to the sensor 21 so that it can be easily disconnected, and the second connector 42 is connected to the input port of the relay board 500 in a closed state (a state where it cannot be connected again once removed). In addition, the 1st connector 41 is corresponded to the connection part to the specific sensor 21 of the specific electric wire of this invention.

  A portion a between the specific sensor 21 and the fixing portion 101a in the first electric wire 31 is the first connector 41 when the control board case 101 is removed from the game board 4 and the position of the control board case 101 is displaced even a little. Is wired so as not to loosen from the specific sensor 21, and the portion b between the fixed portion 101a and the relay board 500 is also the same even if the position of the control board case 101 is displaced by a predetermined amount. (2) Wiring is performed with slack so that no load is applied to the connector 42.

The second electric wire 32 has one end connected to the output port of the relay board 500 and the other end connected to the input port of the main control board 100, so that the signal output from the specific sensor 21 is relayed to the first electric wire 31 and the relay. The data is transmitted to the main control board 100 via the board 500. Further, even if the control board case 101 is removed from the game board 4 and the position of the control board case 101 is displaced from the predetermined position by a predetermined amount, the second electric wires 32 are connected to the relay board 500 and the main control board 100, respectively. The length is set so that no tensile force is applied to the portion to be applied.
3 and 4 indicate electric wires for electrically connecting various electric elements.

  Based on the presence / absence of a signal output from the specific sensor 21, the main control board 100 performs sensor check processing for the presence or absence of disconnection or short-circuiting of the specific sensor 21 and other sensors, as will be described later.

By performing the above, for example, as shown in FIG. 4, the control board case 101 may be used in a period from factory shipment to delivery to the game hall or by a fraudulent act in the game hall using some illegal means. Is illegally removed from the game board 4 and the position of the control board case 101 is displaced rearward (leftward in FIG. 4) from a predetermined position, the first electric wire 31 is pulled rearward together with the control board case 101. The first connector 41 connected to the first electric wire 31 is disconnected from the specific sensor 21.
Further, in this case, in addition to the fact that the first electric wires 31 are mixed with a plurality of cable harnesses and connectors on the back side of the game board 4, the inside of the recess 4 a of the game board 4 where the specific sensor 21 is recessed. Therefore, it is difficult for an unauthorized person to notice that the first connector 41 has been detached from the specific sensor 21. Even if an unauthorized person notices that the first connector 41 is disconnected from the specific sensor 21, the specific sensor 21 is located in the back, so that it cannot be easily recognized visually. It cannot be easily connected to the specific sensor 21. Furthermore, since the second connector 42 cannot be connected to the relay board 500 again when the second connector 42 connected to the first electric wire 31 is detached from the relay board 500, there is evidence that fraud has been performed. Based on this, the presence or absence of fraud can be easily detected visually even when the power is not turned on.

Next, the fraud determination process will be described with reference to FIG.
First, when the power supply device 400 is activated (step S1) by a power switch (not shown), the main control board 100 is activated (step S2).

  In step S2, the RAM of the main control board 100 is initialized, and data for performing the initial control process is set in a predetermined area of the RAM.

  Next, in step S3, an input port process for reading and storing signals output from the specific sensor 21 and other sensors into a register of the main control board 100 via the input port is executed. A sensor check process (step S4) for grasping the read and stored data is executed.

  In step S4, whether or not the specific sensor 21 and other sensors are disconnected or short-circuited is checked. Next, when the main control board 100 determines that there is a disconnection or short-circuit (step S5), the main control is performed. The board 100 executes an error notification control process for transmitting an error signal with a disconnection short circuit to the sub-control board 200 (S6). In the sensor check process, when there is no disconnection or short circuit, after the sensor check process, a detailed description is omitted, but the check process for other electrical elements is continued.

Next, the sub-control board 200 that has received the error signal transmits an error notification signal to the speaker 8, the illumination device 9, and the display device 10, and the speaker 8, the illumination device 9, and the display device 10 that have received the error notification signal An error message is notified (S7).
In this case, when there is a disconnection or short circuit in the wiring circuit of the specific sensor 21 (first electric wire 31), the speaker 8, the lighting device 9 and the display device 10 are disconnected or short-circuited by another sensor. If the notification is performed in a different notification mode, the attendant of the game hall can easily confirm the risk that the control board case 101 is removed from the game board 4 and the main control board 100 is tampered with. .

  The disconnection state in the wiring circuit of the specific sensor 21 is a trace that the control board case 101 is once removed from the game board 4 by an unauthorized person, and the first connector 41 of the first electric wire 31 is connected to the specific sensor. 21 is a state in which the first connector 41 is disconnected from the specific sensor 21 to restore the state in which the first connector 41 is disconnected from the specific sensor 21. It is.

  Although illustration is omitted, if a disconnection or a short circuit occurs in the wiring circuit of the specific sensor 21 after powering on the gaming machine 1 (predetermined time), the main control board 100 immediately gives an error signal. Is transmitted to the sub-control board 200, and if the game is in progress, a control for immediately stopping the game is executed.

  By the above, while fixing the intermediate part of the 1st electric wire 31 for transmitting the signal of specific sensor 21 to control board case 101, control board case 101 is removed from game board 4, and the position of control board case 101 is changed. When the first connector 41 of the first electric wire 31 is easily detached from the specific sensor 21 when displaced from a predetermined position, the main board 31 is removed from the game board 4 by an unauthorized act. After the control board 100 is tampered with, the first connector 41 of the first electric wire 31 is disconnected from the specific sensor 21 even when the main control board 100 and the control board case 101 are returned to the original state. Therefore, it can be surely found that there is a risk of fraud. Moreover, since the 1st electric wire 31 is mixed in the back side of the game board 4 with other cable harnesses, and the specific sensor 21 is arrange | positioned in the recessed part 4a of the game board 4, it is under illegal act In addition, it is not easily noticed that the first connector 41 of the first electric wire 31 is disconnected from the specific sensor 21.

Although the embodiment of the present invention has been described above, the following modifications and changes can be made to the present embodiment without departing from the spirit of the present invention.
(1) Instead of fitting the first connector 41 of the first electric wire 31 to the specific sensor 21, the first electric wire 31 is directly connected to the specific sensor 21 so as to be easily disconnected.
(2) Instead of the magnetic detection sensor, the specific sensor 21 is another proximity sensor.
(3) The second electric wire 32 is omitted and the specific sensor 21 and the main control board 100 are directly connected with the first electric wire 31.
(4) The present invention may be used not only for the control board case 101 containing the main control board 100 but also for other control boards such as the sub control board 200.
