Since the detection signal is generated while the contact between the two is released by removing, it becomes difficult to remove the selector device 30 while holding down the monitoring switch 62 (so as not to cause a signal change), which is more effective. To prevent fraud.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously. For example, in the above-described embodiment, the monitoring switch 62 serving as the detection unit is installed on the bracket 100 side, but may be installed on the selector device 30 side. Further, the detection means is not limited to the above-described push-type switch element as long as it generates a detection signal when the selector device is attached to or detached from the bracket. For example, an optical sensor or a contact state is detected. You may comprise by the sensor etc. which do.

  In addition, the notifying means for notifying the history information about attachment / detachment is not only visually notified by the liquid crystal display unit 2a, but also can be confirmed visually using the speakers 21L and 21R, or a combination of both. May be. In the configuration described above, the control board for executing the slot machine game is used to notify the attachment / detachment history information on the liquid crystal display unit 2a of the slot machine, the speaker, etc., but the base 31 of the selector device 30 is notified. In addition, a light emitting element, a speaker, a liquid crystal display unit, and the like may be attached to notify the attachment / detachment history information. Further, the monitoring unit 400 described above is installed at a position different from the selector device 30, but the selector device 30 may have a function of managing time in the same manner as the monitoring unit.

  Furthermore, in the embodiment of the present invention, the selector device has been described as an example of the internal device installed inside the slot machine, but the present invention can also be applied to other internal devices. For example, various internal devices that are not usually removed from the inside of the slot machine and can be cheated by being removed, for example, basic operations of the game by the slot machine and its accompanying lamps, sounds, The present invention can also be applied to a control board (main control circuit board and sub control circuit board in FIG. 8) for controlling images and the like, a hopper unit for paying out game media, a power supply unit for supplying power, and the like.

  In this case, as a base member to which such an internal device is attached or detached, there is an internal frame provided in advance on the slot machine side, or a fixing member such as a bracket attached to the internal frame of the slot machine. included. Further, such a base member may include a component that performs a part of the function of the internal device to be mounted.
