Further, as shown in FIG. 11B, which is a BB cross-sectional view of FIG. 11A, the power switch 701 is positioned so as to partially overlap the upper and lower slide covers 711, so that the upper and lower cover cases 711 are interposed. It can be confirmed that the power switch 701 is visible.

  The setting key switch 244 may be provided in the power supply device 252 as shown in FIG. In this way, when changing the setting, the power switch 701 and the setting key switch 244 must be operated while operating the upper and lower slide covers 711, so that it is further difficult to perform an illegal act.

  Next, an operation method of the vertical slide cover 711 will be described with reference to FIG.

  As shown in FIG. 12A, in a normal state where the upper and lower slide covers 711 are not touched, the slide cover 711 is lowered to the closed position by its own weight. From this state, when the finger is applied to the opening protrusion 717 and shifted upward, the opening protrusion 717 is caught, and the upper and lower slide covers 711 are also moved upward, as shown in FIG. Thus, the power switch 702 can be operated. However, if the finger is released from the opening projection 717, the vertical slide cover 711 falls due to its own weight and closes. For example, after opening the vertical slide cover 711 with the left hand, Therefore, an operation of operating the power switch 701 with the right hand is necessary. Here, when trying to turn on the power switch by an unauthorized method, in general, an instrument is inserted from the gap between the casing 101 and the front door 102 to operate the power switch 701. The power switch cannot be operated due to the failure of 711. Even if the upper and lower slide covers 711 are opened, the power switch 701 must be operated while keeping the opened state, so that unauthorized operation becomes very difficult.

  As described above, the gaming machine of the present invention is a gaming machine comprising a gaming control device that controls a gaming device, and a power supply device that supplies power to the gaming control device, wherein the power supply device includes: A power switch for switching whether or not to supply power to the game control device; and a protective cover for covering the power switch, the protective cover being in an open state in which the power switch can be operated; and operating the power switch It is characterized by including a slide cover that is switched by moving up and down in an impossible closed state.

  In the embodiment described above, the vertical slide cover 710 that slides in the vertical direction is provided in the vicinity of the power switch so as to be freely opened and closed.

  Therefore, even if an attempt is made to operate the power switch 701 with a fraudulent instrument such as a wire, the vertical slide cover 711 becomes an obstacle, and fraud can be prevented. Even if the upper and lower slide covers 711 are opened, the upper and lower slide covers 711 are opened with one unauthorized device, and the power switch 701 is very difficult to be operated.

  In another aspect of the present invention, the slide cover is made of a translucent member.

  In the above-described embodiment, a translucent resin is used as a member that forms the upper and lower slide covers 711.

  Therefore, even when the slide cover is in the closed state, the state of the power switch inside the protective case cover 710 can be confirmed, which is highly convenient.

  According to another aspect of the present invention, the slide cover is further provided with a protrusion.

  In the embodiment described above, the opening protrusion 717 is provided at the lower part of the upper and lower slide covers 711.

  Therefore, when the upper and lower slide covers are in the open state, the upper and lower slide covers 711 can be smoothly moved up and down by moving the upper protrusions 717 up and down with a finger.

  According to another aspect of the present invention, the power supply device further includes a case body capable of accommodating a power supply board therein, and the protective cover is engaged with a shaft portion provided in the case body. The power switch is configured to rotate between an open state where the power switch can be operated and a closed state where the power switch cannot be operated.

  In the above-described embodiment, the shaft portion 713 serving as the shaft center when rotating to the upper surface portion and the lower surface portion of the protective case cover 710 is provided, the bearing hole 703 is provided in the case body 700, and not only the upper and lower slide covers 711 but also the protection. The power switch 701 can be operated even when the case cover 710 is opened and closed.

  Therefore, the operation of the power switch can be easily performed according to the required application.

  Further, in another aspect of the present invention, the case body further includes an external output connector terminal, and the protective cover is connected to the external output connector terminal when the protective cover is in a closed state. An opening for leading the wiring out of the protective cover is provided.

  In the embodiment described above, the case body 700 is provided with the connector 702 that outputs power from the power supply device 252 to the outside, and further, the harness connected to the connector 702 can be externally connected even when the protective case cover 711 is closed. An upper harness opening 719 and a lower harness opening 720 that can be led out are provided.

  Therefore, it is possible to prevent fraud with respect to the body, and even when the harness is connected, fraud can be reliably prevented without hindering the closing operation.

  In another aspect of the present invention, the case body is further provided with a stepped portion capable of accommodating the protective cover, and the protective cover is planar with a side length shorter than a side length of the stepped portion. It is characterized by a three-dimensional shape forming a part.

  In the embodiment described above, the stepped portion is provided in the case body 700 so that the protective case cover 710 can be accommodated.

  Therefore, since the protective case cover 710 does not jump out of the case body 700 and falls within the dimensions of the case body 700, maintenance of the apparatus is easy without interfering with other gaming devices.

  In this embodiment, the vertical slide cover 711 is dropped by its own weight. However, like the spring for biasing the protective case cover 710, the vertical slide cover 711 is biased downward using an elastic body. It may be configured. In that case, since a stronger force works downward, the opening operation becomes difficult, and more reliable fraud prevention can be realized. In addition, if the spring is biased, the slide direction of the slide cover 711 may be not the vertical direction but the horizontal direction.

  As mentioned above, although the Example of this invention was described, it has only illustrated the specific example and does not specifically limit this invention. Further, the actions and effects described in the embodiments of the invention only list the most preferable actions and effects resulting from the present invention, and the actions and effects according to the present invention are described in the embodiments of the present invention. It is not limited to what was done.

  The present invention can be applied to a game machine used in a game machine represented by a slot machine, a pachinko machine, and the like.
