[0002]

2. Description of the Related Art In general, a pachinko gaming machine has a game board storage frame for storing a game board mounted on a back surface of a front frame rotatably supported on one side of a main body frame. Various control devices are mounted on the back mechanism panel provided on the back of the frame. Conventionally, as a type of this control device, there is generally a case where a game control device for controlling an accessory or the like in a game area and a discharge control device for controlling a prize ball discharge device are provided. The configuration provided by means of this was not particularly adopted.

[0003] That is, the structure of a typical conventional pachinko gaming machine is an AC24 led from a step-down transformer outside the gaming machine.
V AC power is supplied to the game control device and the discharge control device via a terminal board including a power switch provided on the upper right of the back of the game machine, and each control device converts it to DC power used by each control device. The necessary DC power is generated and used by its own control device, while the game control device uses the DC power generated by a special map display device (a type of variable display device).
Is also supplied to the display control device for.

In such a configuration, there is a problem that if a failure occurs on the game control device side, the display control device is also affected. Therefore, recently, a power supply device is provided independently for each control device, and a DC power supply used in each control device is generated there and sent separately, so that a failure occurs in the game control device temporarily. If it does,
Display controls are no longer affected. Conventionally, this power supply device is provided in the center of the back mechanism panel or in an area below the center.

In recent years, control devices have been divided into functions in order to improve the efficiency of inspection work. In addition to the above-mentioned game control device and ball discharge control device, a firing control device for controlling the firing of game balls, and light emission of side lamps and the like. A decoration control device for controlling the light emission of the decoration member and a sound control device for producing effects such as sound effects are also provided as separate and unitized units. Even in the form of a pachinko gaming machine having a large number of control devices, the power supply device is conventionally provided in the center of the back mechanism board or in an area below it.

[0006]

However, in the case of a conventional gaming machine having no independent power supply device, particularly a pachinko gaming machine, each of the control devices uses an AC power supplied from the outside to control the DC power used in each control device. Since the power supplies are separately generated, the board area of each control device also increases, and the limited space on the back of the gaming machine cannot be used effectively.

In the case of configuring a pachinko game machine having an independent power supply for each control device,
Conventionally, a power supply device is installed in the center of the back mechanism board or in an area below the back mechanism board, but such an installation form effectively uses the limited space on the back of the gaming machine and prevents malfunction due to noise. In doing so, the power supply device is not necessarily installed in an optimal manner.

An object of the present invention is to solve the above-mentioned problems and to provide a gaming machine in which a power supply device is arranged so as to effectively use a limited space on the back surface of the gaming machine and prevent malfunction due to noise. It is in.
