Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit board mounting structure of a pachinko machine in which various circuit boards are provided on the back side of the pachinko machine.

[0002]

2. Description of the Related Art In recent years, a general pachinko machine has a main control board for controlling the entire pachinko machine and a ball dispensing device on the back of a mechanism plate for mounting back parts mounted on the back side thereof. Various circuit boards such as a payout control board, an audio control board for controlling audio, and a power supply board are arranged side by side in a plane.

[0003]

The recent pachinko machines are:
Since control boards are provided separately for each control target, the number of circuit boards mounted on the mechanism board tends to increase. Furthermore, with the recent increase in the number of functions of pachinko machines, the number of electronic components mounted on each circuit board increases, and each circuit board tends to be larger. For this reason, in the conventional configuration in which various circuit boards are arranged in a plane along the back surface of the mechanism board, a large area of the mechanism board is occupied by the circuit board, and the center of the mechanism board is reduced. It is becoming difficult to secure an opening for arranging accessory units and a space for arranging other back parts.

[0004] The present invention has been made in view of such circumstances, and an object thereof is to reduce the area occupied by the circuit board on the back surface of the pachinko machine as compared with the conventional art, and to provide a back structure for the pachinko machine. It is an object of the present invention to provide a circuit board arranging structure of a pachinko machine which can increase the degree of freedom of design of a pachinko machine.

[0005]

According to a first aspect of the present invention, there is provided a circuit board arrangement structure for a pachinko machine according to the first aspect of the present invention, wherein a plurality of circuit boards are superposed on each other so as to be substantially parallel to the back surface of the pachinko machine. It is a configuration in which it is attached. In this configuration, a plurality of circuit boards are mounted on top of each other,
To that extent, the area occupied by the circuit board on the back surface of the pachinko machine can be made smaller than before, and the space for arranging other back components can be expanded. Moreover, since a plurality of circuit boards are superimposed almost in parallel along the back surface of the pachinko machine, the circuit board is mounted on the back surface of the pachinko machine at a right angle to save space, compared to the case where the space is saved. And the depth of the pachinko machine does not need to be large.

A general pachinko machine has a structure in which a large number of circuit boards are arranged on the back side of a mechanism plate for mounting back parts mounted on the back side of the pachinko machine.
As described in claim 2, a plurality of circuit boards may be superimposed on the back side of the mechanism plate and attached substantially parallel to the mechanism plate. By doing so, the area occupied by the circuit board in the mechanism board can be reduced, and the arrangement space for other back components of the mechanism board can be increased.

Further, a circuit board which does not require inspection, inspection, repair, etc. is placed on a lower side, and a circuit board, which requires inspection, inspection, repair, etc., is superposed and mounted thereon. It is good to have a configuration. With this configuration, it is not necessary to make the upper circuit board detachable or openable in order to perform inspection, inspection, repair, etc. of the circuit board. Inspection, inspection,
Repairs and the like can be easily performed.

In general, the power supply board hardly breaks down and is not illicitly modified. On the other hand, the control board such as the dispensing control board has a higher failure frequency than the power supply board. In addition, there is a possibility that unauthorized modification and the like may be performed.
Therefore, when the power supply board and the control board are superimposed and attached, it is preferable that the power supply board is placed down and the control board is overlaid thereon. In this way, the control board can be easily inspected, inspected, repaired, and the like, and the control board does not need to be detachable or openable.

Further, a plurality of circuit boards may be mounted on each other so as to sandwich the mechanism plate therebetween. With this configuration, the spaces on both front and rear sides of the mechanism plate can be effectively used, and the arrangement space for other back parts can be further increased.
