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 that constitutes a front portion of the gaming machine is provided as a door body that can be opened and closed from the viewpoint of maintenance and the like. The game machine is provided with a locking device so that the doors such as the front frame cannot be opened in the game hall by anyone other than the clerk without permission.

Nevertheless, while the game hall is open, for example, the locking device of a pachinko machine is illegally unlocked to open the front frame, and wires such as wires and thin plate-shaped members called "cell plates" are opened. There were cases where a fraudulent act such as inserting a prize winning device or the like on the game board surface and forcibly opening it to obtain a large number of game media was performed.

In order to prevent this, in recent years, an opening detection switch that detects the opening of the door such as the front frame is provided, and when the door is opened, an opening signal is output, etc. Is also used to notify the hall computer in the game hall.

For example, in a pachinko machine, there is a pachinko machine in which an opening detection switch for a front frame is provided on an upper portion or the like of a resin base that constitutes the main body (inner frame) of the gaming machine (see, for example, Patent Document 1). With this configuration, the switch portion of the opening detection switch is pressed by the front frame to be in the retracted state when the front frame is closed. 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.

JP, 2006-263026, A

However, in the above-described opening detection switch, only when the locking device is unlocked and the front frame is opened to some extent, the switch portion is in the protruding state and the opening of the front frame is detected. Therefore, if the opening detection switch is provided near the rotation axis side (for example, the left side) of the front frame as in the above-described conventional technique, the opening may not be detected even if the front frame is slightly opened. That is, there is a possibility that the above-mentioned fraudulent acts may be performed by opening the front frame slightly and inserting a wire or the like through the slight gap. For example, in the case where the above-mentioned misconduct is carried out by inserting a wire or the like through a slightly opened gap while forcibly opening only the open side lower part (for example, lower right part) of the front frame without opening the entire front frame However, it is difficult to detect it with the above-mentioned conventional technology.

In addition, the above-mentioned problem has been described by taking the front frame that is provided to be openable and closable with respect to the gaming machine body of the pachinko machine as an example, but for example, with respect to the gaming machine body (inner frame) of the pachinko machine, open the gaming machine body. The same problem may occur because there is a possibility that an illegal act such as illegally operating or replacing the control device provided on the back side of the main body will be performed. That is, the above problem is a problem that similarly occurs in a gaming machine provided with various doors that can be opened and closed, and is a problem that is applicable not only to pachinko machines but also to other gaming machines.

The present invention has been made to solve the above problems, and an object thereof is to provide a gaming machine capable of improving the door opening detection performance.
