Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine, an arrangement ball machine, a sparrow ball game machine, a rotary game machine, and the like.
In particular, it relates to the structure of the board case.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a power supply board, a main control board, a payout control board, a voice control board, a lamp control board, and the like are provided on the back side of the game machine body. I have.

A conventional board case is divided into a case body including a front plate portion and a case lid including a back plate portion, and an opening having a size larger than the size of the board is provided on a side of the case body facing the front plate portion. A part is formed. And when assembling the board,
Separate the case body and the case lid, insert the board into the case body from the opening side of the case body so as to be able to be inserted and removed in the thickness direction, and then attach the case lid to the opening side of the case body. Then, fix the board by sandwiching the board from both sides in the thickness direction with the case body and the case lid, or fix the board with screws etc. in the case body, and then close the opening side of the case body with the case lid Like that.

[0004]

The conventional board case is
Since the board is inserted into the case body in the thickness direction, it is necessary to form a large opening in the case body corresponding to the front plate, and the case lid also covers the large opening. It needs to be just the size.

For this reason, in the conventional board case, there is a problem that the rigidity of the case body and the case lid is structurally reduced, and the durability is lacking. In particular, in the case of a flat substrate case, not only the case lid but also the case main body becomes flat and a large opening is formed in the flat case main body, so that its rigidity is extremely large. It becomes a problem.

In a board case used in a ball-and-ball game machine such as a pachinko machine, it is desirable to minimize the size of the opening in order to prevent fraud. However, in the conventional board case, the opening on the case body side is very large, and thus there is a problem that fraud is likely to occur.

SUMMARY OF THE INVENTION In view of the above problems, the present invention can reduce the size of the opening on the case body side, and at the time of insertion of the board, the projections such as the pins of the electric parts projecting to the back side thereof come into contact with the case body. An object of the present invention is to enable a board to be easily inserted into a case body without any problem.

[0008]

According to the present invention, a substrate case 3
In the gaming machine in which the substrate 33 on which the electric components 40 and 41 are mounted is accommodated in the substrate 4, the substrate case 34 has an opening 37 corresponding to one end of the substrate 33 and the opening 37. A case-like body 38 into which the substrate 33 is inserted in the direction of the plate surface; and a case lid 39 attached to the opening 37 side of the case body 38. When the substrate 33 is inserted,
A guide portion 52 for guiding the substrate 33 away from the back plate portion 43 facing the back side of the substrate 33 is provided.

When the power supply board 33 is incorporated in the power supply board case 34, the case body 38 and the case lid 39 are first separated, and the power supply board 33 is placed between the pair of peripheral walls 44 on the opening 37 side of the case body 38. 9, the back side of the power supply board 33 is placed on each guide portion 52 as shown in FIG. 9, and in this state, the power supply board 33 is moved along the guide portion 52 into the case body 38 in the direction indicated by the arrow a. Insert

In this manner, the electric components on the front side of the power supply board 33, the connectors 41, and the like are connected to the front plate portion 4 of the case body 38.
The power supply board 33 is easily inserted into the case main body 38 without contacting the power supply board 33 or the protrusions such as the terminal pins 41a projecting rearward from the power supply board 33 to the back plate portion 43 side. be able to.

When the power supply board 33 is inserted into the case main body 38 along the guide portion 52, the front end thereof is
Is guided toward the holding portion 53 side, and is held between the holding portion 53 and the step portion 49 of the case body 38.
In this state, the power supply board 33 is inclined in the case main body 38 as shown by a virtual line in FIG. 9, and a part of the connector 41 is fitted into the opening 50 on the step portion 48 side.

Next, the front end of the holding portion 57a is aligned with the back side of the rear end portion of the power supply board 33, and the rear end side of the power supply board 33 is lifted by the holding portion 57a toward the step portion 48. The connector 41 fits into the opening 50 and projects outside the step portion 48. Then, in this state, the case cover 39 is aligned with the opening 37 of the case body 38, and this case cover 39
Is fitted into the case body 38, the opening 37 of the case body 38 is closed by the case lid 39, and then the screws 59
Then, the case lid 39 is fixed to the case body 38. As a result, the power supply board 33 in the case body 38 is
It can be fixed by being sandwiched between the front and back sides between the holding portions 53 and the holding portion 57a.

In this embodiment, an opening 37 is formed at one end of a flat box-shaped case body 38, and the opening 37 is formed.
By inserting the power supply board 33 in the direction of the plate surface from the side so as to be freely inserted and removed, the opening 37 of the case body 38 can be made small, and the rigidity of the case body 38 and the case lid 39 can be easily secured, and the rigidity is improved. I do. Further, since the opening 37 can be made small, it is possible to easily take measures against fraud and the like.

The power supply board 33 is provided in the case body 38.
There is a guide portion 52 for guiding in the insertion direction in a state in which the power supply board 33 is separated from the back plate portion 43, so that protrusions such as terminal pins 41 a on the back side of the power supply board 33 do not interfere with the back plate portion 43, and The board 33 can be easily inserted into the case body 38. Moreover, the case cover 3 is inserted into the opening 37 of the case body 38.
By mounting the power supply 9, the power supply board 33 can be fixed in the case main body 38, so that the power supply board 33 can be easily fixed in the case main body 38. Further, by attaching the case lid 39, the connector 41 of the power supply board 33 is connected to the case body 38.
Since the connector 41 can be fitted into the opening 50 on the side, there is no need to fit the connector 41 into the opening 50 in advance.
