Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Generally, in a gaming machine such as a pachinko machine, a front frame or the like constituting a front part of the gaming machine is provided as a door body that can be opened and closed from the viewpoint of maintenance or the like. The gaming machine is provided with a locking device so that a person other than the store clerk cannot open the door body such as the front frame in the gaming hall without permission.

  Nevertheless, during operation at the game hall, for example, the locking device of the pachinko machine is illegally unlocked and the front frame is opened, and wire such as a wire or a thin plate member called a “cell plate” is used. There have been cases in which an illegal act of compulsorily releasing a winning device on the game board surface and acquiring a lot of game media has been performed.

  In order to prevent this, in recent years, an opening detection switch for detecting the opening of a door body such as a front frame is provided, and when the door body is opened, an opening signal is output. A system is also adopted in which is notified to the hall computer of the game hall.

  For example, in a pachinko machine, there is one in which an opening detection switch for a front frame is provided on an upper portion of a resin base constituting the gaming machine main body (inner frame) (see, for example, Patent Document 1). In this configuration, the switch portion of the open detection switch is pressed by the front frame when the front frame is closed, and is in an immersive state. On the other hand, when the front frame is opened, the switch portion is in a protruding state, and the opening of the front frame is detected.

  However, in the above-described opening detection switch, the switch portion is in a protruding state only when the locking device is unlocked and the front frame is opened to some extent, and the opening of the front frame is detected. For this reason, when the opening detection switch is provided closer to the rotation axis side (for example, the left side) of the front frame as in the above-described prior art, the opening may not be detected to the extent that the front frame is slightly opened. That is, the front frame is slightly opened, and a wire rod or the like is inserted through the slight gap, so that there is a risk that the above-mentioned fraudulent activity is performed. For example, when the above fraud is performed without opening the entire front frame and inserting the wire from a slightly opened gap with the open side lower part (for example, the lower right side) of the front frame forcibly opened. Therefore, it is difficult to detect the above-described conventional technology.

  In addition, although the said malfunction demonstrated the front frame provided with opening and closing with respect to the game machine main body of a pachinko machine as an example, for example, the game machine main body (inner frame) of a pachinko machine opened the game machine main body. A similar problem may occur because there is a risk that an illegal act such as illegally operating or replacing the control device provided on the back side of the main body may be performed. That is, the above-mentioned problem is a problem that similarly occurs in gaming machines having various doors that can be opened and closed, and is a problem that applies not only to pachinko machines but also to other gaming machines.
