There is a problem that it adheres and causes poor connection.

In addition, in the case where the circuit board unit is configured to be detachable, it is necessary to provide a detachable engagement means for both the board unit and the mounting member for mounting the circuit board unit on the back side of the gaming machine. In addition, in order to securely attach and detach, it is required to improve the accuracy of the engaging portion at the time of manufacturing, and there is a problem that the work of mounting the board unit easily takes time.

Therefore, an object of the present invention is to quickly and easily attach and detach the circuit board unit in the ball game machine using the circuit board unit as described above, and to attach the connector part of the circuit board unit in the attached state. It is to provide a mounting structure that can protect from damage and adhesion of dust.

[0006]

[Means for Solving the Problems]

 The present invention is a circuit board unit mounting structure for controlling electrical equipment used in a ball game machine, wherein a first connector section provided in the circuit board unit and the first connector section are provided. A connector supporting member having a mounting opening for removably receiving a portion of the circuit board unit, a second connector portion electrically connected to the first connector portion received by the connector supporting member, and a back surface of the ball game machine. And a hinge part for rotatably attaching the connector supporting member.

In the present invention, it is preferable to provide protrusions for sandwiching the above-mentioned circuit board unit on opposite surfaces inside from the mounting opening of the connector supporting member.

[0008]

[Action]

 When mounting the circuit board unit, the first connector portion is electrically connected to the second connector portion by inserting the portion of the circuit board unit provided with the first connector portion from the mounting opening of the connector supporting member. At the same time, the circuit board unit is received and supported by the connector support member. As a result, the connector portion of the circuit board unit is protected from the outside, and there is no risk of damage or dust adhesion.

During maintenance work, when inspecting or exchanging electrical components from the back side of the ball game machine, if the connector support member is rotated around the hinge as a fulcrum, the circuit board unit will actually move. You can work with it removed. Further, if necessary, the circuit board unit can be easily removed from the connector supporting member.

Further, by providing a protrusion that holds the circuit board unit inside the mounting opening of the connector support member, both sides of the circuit board unit can be reliably supported inside the connector support member, and It is possible to prevent an extra load from being applied.

With such a protruding portion 72, both sides of the circuit board unit 70 mounted therein can be reliably supported from the mounting opening 63 of the connector bracket 64, and the two connected connector portions 62 and 65 are not loaded. Can be prevented. As shown in FIG. 4, on the side surface of the circuit board unit 70 on the side of the first connector 62, a recess 73 into which the respective projections 72 are fitted is formed.

Next, the operation of the circuit board unit mounting structure of the embodiment will be described.

First, when mounting the circuit board unit 70 in the state of FIG. 4, the connector bracket 64 is rotated to a position where the circuit board unit 70 can be easily mounted, and the first connector of the circuit board unit 70 is rotated. The portion on the side of the portion 62 is inserted from the mounting opening 63. As a result, the first connector portion 62 is electrically connected to the second connector portion 65, and the circuit board unit 70 is received and supported by the connector bracket 64. As a result, the connector portion of the circuit board unit 70 is protected from the outside, so that there is no risk of damage or dust adhesion.

When the circuit board unit 70 is mounted in the connector bracket 64, the circuit board unit 70 is cantilevered in the connector bracket 64, so that an excessive load is likely to be applied to the connector portion. The protruding portion 72 provided in 64 can hold the circuit board unit 70 without applying a load to the connector portion.

When the mounting of the circuit board unit 70 is completed, the connector bracket 64 is rotated to the position shown in FIGS. 4 and 5, and the locking claw 61 of the board case bracket 52 is engaged with the circuit board unit 70. This completes the installation.

At the time of maintenance work, by removing the locking claw 61 of the board case bracket 52 and rotating the connector bracket 64, the work can be carried out in the same state as when the circuit board unit is actually removed. You can Further, during a game, for example, when a failure such as disconnection of the wiring of the variable display device 9 of FIG. 1 occurs, after rotating the connector bracket 64 as described above, the stopper 59 of the substrate case bracket 52 is fixed. By removing the above, it is possible to repair the wiring by removing the board case bracket 52 from the rear surface of the rear panel unit 51.

[Effect of the device]

 As described above, according to the present invention, when the circuit board unit is mounted on the connector supporting member, the two connector parts electrically connected inside the connector supporting member are protected from the outside, and thus may be damaged. There is no risk of dust and dirt adhering.

Further, at the time of maintenance work, the connector supporting member may be rotated, and if necessary, the circuit board unit can be easily removed from the connector supporting member, so that workability is improved.

Further, since the connector supporting member is rotatable about the hinge portion as a fulcrum, the connector supporting member can be rotated by introducing the wiring connecting to the connector portion from the rotation supporting point side of the connector supporting member into the inside. Wiring does not get in the way when moving.
