Description

  The present invention relates to a power supply device and a gaming machine for supplying power necessary for the operation of the gaming machine.

  One type of gaming machine is a spinning machine, for example, a slot machine. The slot machine includes a plurality of reels as rotating bodies with a plurality of symbols attached thereto, and each reel starts rotating when a player inserts a medal and operates a start lever. After each reel starts rotating, each reel is sequentially stopped by operating a stop button or elapse of a predetermined time.

  Also, in the slot machine, a lottery is performed on condition that the medal is inserted and the start lever is operated, and the lottery result is a win, and the player has to stop the winning symbol on the preset active line. As a result, a predetermined number of medals are paid out, or a special gaming state (bonus game or the like) advantageous to the player occurs.

  In addition, such a slot machine includes a box-shaped housing having an opening on the front surface side, and a front door attached to the front surface side of the housing so as to be openable and closable. It is arranged and used for games with the front door covering the opening. In addition, a power supply device for supplying power to each part of the slot machine is provided inside the casing, and the slot machine is operated by the power supplied from the power supply device.

  By the way, on the front side of the power supply unit, there are a power switch for operating the slot machine, a medal collection switch for collecting game medals, and a setting switch for setting the payout rate of the slot machine, etc. An operation plate having operation switches is provided, and each operation switch can be operated in a state where the front door is opened, so that maintenance work of the slot machine, work-out management work, and the like can be performed.

  In other words, by operating the medal recovery switch with the front door open, the game medals are collected by forcibly paying out the game medals from the medal payout device. Similarly, the setting is made with the front door open. By controlling the switch and setting the output rate of the slot machine, the output of the slot machine is managed.

  Such a power supply device can be isolated from the outside by covering the opening of the housing with the front door, and each operation switch on the operation plate of the power supply device will not be illegally operated unless the front door is opened. ing.

  However, there has been a problem that, for example, a medal collection switch, a setting switch, or the like is illegally operated using a tool such as a cell or a wire during a game and a game medal is illegally acquired. Therefore, cover the surface of the operation plate on which each operation switch is installed with a cover, and take measures to make it difficult for the medal recovery switch, setting switch, etc. to be illegally operated using tools such as cells and wires. It was.

  However, since the cover is fixed to the operation plate by screwing or the like, it is necessary to remove the cover from the operation plate every time the slot machine maintenance work or the ball management work is performed. The work and the issue management work have become complicated. Also, after maintenance of the slot machine and management of the ball, if the hall staff forgets to re-fix the cover to the operation plate, or if the cover is not sufficiently fixed to the operation plate, countermeasures against fraud are ineffective. In some cases it was sufficient.

  In order to solve such a problem, in Patent Document 1, an operation switch for performing a predetermined operation is provided, and an operation plate provided on the front side of the power supply device and the operation plate can be opened and closed so as to cover the surface. And a cover urging means for urging the cover to the closed position. The ribs connected to the periphery of the cover are connected to the periphery of the operation plate.
