  When the control device 64 is attached to the rear side of the fraud prevention member 58, the sensor storage space 46 is covered with the control device 64 from behind and cannot be seen from behind the installation member 20 (see FIG. 5). However, since the sensor accommodation space 46 is filled with the fraud prevention member 58, no illegal parts are installed in the space 46, and a situation where illegal acts continue for a long time can be prevented. Moreover, since the to-be-fixed part 61 for attaching the control apparatus 64 is provided in the fraud prevention member 58, the control apparatus 64 cannot be attached in the state which removed the fraud prevention member 58. FIG. That is, when an unauthorized person removes the fraud prevention member 58 and installs an unauthorized part in the sensor accommodating space 46, the control device 64 cannot be attached to the lower facing surface wall 36a in a normal state. It is easy to detect fraudulent activity because it is not attached.

  Here, in the second space 46c in which the rear end portions of the normal winning sensor 29 and the magnetic sensor 47 are accommodated in the sensor accommodating space 46, in a state where the fraud prevention member 58 is removed from the sensor accommodating portion 45, Necessary gaps are defined between the sensors 29, 47 and the inner side surfaces 56a, 56b, 56c, 56d. For this reason, it is conceivable that unauthorized parts are installed in the gap. However, since the anti-fraud member 58 of the embodiment is provided with an extending portion 60f that protrudes forward from the insertion portion 60 that fills the first space 46b, when an illegal component is installed in the gap, The extension part 60f cannot be inserted into the second space 46c until the extension part 60f interferes with an unauthorized part and the locking part 62 is locked to the locked part 45c. That is, since the fraud prevention member 58 is not attached to the sensor housing portion 45, it is possible to easily find out that an unauthorized part is installed in the second space 46c (sensor housing space 46).

  In the embodiment, since the positioned portions 52 and 63 for positioning the control device 64 are provided not only on the fraud prevention member 58 but also on the lower facing surface wall 36a, the control device 64 is provided for the lower facing surface wall 36a. Can be mounted in the correct position. Further, since part of the positioned portions 52 and 63 are provided on the lower facing surface wall 36a, when a load is applied to the control device 64, not only the fraud prevention member 58 but also the installation member 20 receives the load. Thus, it is possible to suppress a large load from being applied to the fraud prevention member 58. Since the plurality of reinforcing ribs 59f are provided on the upper edge portion of the base portion 59 where the fixed portion 61 is provided in the tamper preventing member 58, the strength of the fixed portion 61 can be improved, and the tamper preventing member 58 is provided. It is possible to mount the control device 64 stably. Further, when the control device 64 is attached to and detached from the tamper prevention member 58, the plunger member 71 of the fixture 69 may be pushed and pulled with the operation portion 71a as in the embodiment. Since the portion of the base 59 where the fixed portion 61 is provided is reinforced by the reinforcing rib 59f, it is possible to prevent the tamper-proof member 58 from being damaged by the load applied when the plunger member 71 is operated.

  In the pachinko machine 10 of the embodiment, in the state where the control device 64 is attached to the rear side of the fraud prevention member 58, the locking portions 62, 62 for attaching the fraud prevention member 58 to the sensor accommodating portion 45 are the control device. 64, the tamper-proof member 58 cannot be removed from the sensor housing portion 45 unless the control device 64 is removed. That is, in order to install unauthorized parts in the sensor accommodating space 46, it is necessary to perform the work of removing the control device 64 from the fraud prevention member 58. This work is troublesome, and fraud can be suppressed. .
