Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back mechanism including a control device and a power relay device in a pachinko machine.

[0002]

2. Description of the Related Art The back mechanism of a pachinko machine disclosed in Japanese Patent Application Laid-Open No. 6-47156 converts an AC power supply such as AC 24 volts received from an island-side power supply called an island transformer in a pachinko parlor into a DC power supply. A power supply device having a function is arranged separately from a plurality of control devices such as the accessory control device and the launch control device, and supplies a necessary DC power to each control device from the single power supply device.

[0003]

In the back mechanism of the conventional pachinko machine, a power supply relay device for relaying power supplied from the power supply device to the control device is provided, so that the pachinko machine can be used commonly for different types of pachinko machines. Although it is possible to obtain the obtained power supply device, the wiring connecting the power supply device and the power supply relay device, the wiring connecting the power supply relay device and the control device, and the like intersect complicatedly depending on the place where the power supply relay device is arranged. It becomes form.

Accordingly, the present invention provides a back mechanism of a pachinko machine which can simplify the form of wiring.

[0005]

According to the present invention, there is provided a control device provided on the back side of a pachinko machine, and a power supply relay device provided on the back side of the pachinko machine for relaying DC power to the control device, The power supply relay device is disposed on a component attachment body for attaching the control device to a game board. Therefore, according to the present invention, for example, a main control device in which the control device electrically controls the entire game, and a slave control device in which the game operation component is electrically controlled by a command output in one direction from the main control device. However, since the power supply relay device is arranged near the control device, wiring for connecting the power supply device to the power supply relay device, wiring for connecting the power supply relay device to the control device, etc. It is organized in order for each system, and the wiring form can be simplified. Further, in the present invention, if the control device is a main control device for electrically controlling the entire game, the main control device or the main control device outputs the signal in one direction from the power supply device via the power supply relay device. Even if the DC power is supplied to the slave control device that electrically controls the game operation parts by the command, the wiring connecting the power relay device and the main control device, and the power relay device and the slave control device are connected. Wiring, wiring connecting the main control device and the slave control device, and the like are collected for each control system. Further, if the power relay board is arranged between the winning ball guiding member fixed to the game board covered with the component mounting body and the component mounting body, the power relay board is covered with the winning ball guiding member. An electrical short circuit (short circuit) of the power supply relay board via the winning ball without the relay board interfering with the winning ball can be prevented.
Further, in the present invention, if the eaves located above the winning ball guiding member are provided on the component mounting body, the eaves prevent the ball from entering the gap between the component mounting body and the winning ball guiding member. Collision between the ball and the power supply relay board can be prevented. Further, in the present invention, the wire connected to the component mounting body is drawn out from the gap between the eaves provided on the component mounting body and the winning ball guiding member, thereby preventing the ball from being caught between the winning ball and the wiring. be able to.
Further, in the present invention, if the eaves are extended in the lateral direction of the component mounting body, the eaves become a skeleton of the component mounting body, the strength of the component mounting body is increased, and the mounting posture of the main control device is stabilized.
