Things. 2. Description of the Related Art In recent years, pachinko machines have come to be configured by adopting various kinds of electronic components such as ICs and LSIs. It must be protected and must also be protected from dust and the like. For this reason, conventionally, such electronic components as described above have been put together on a circuit board and stored in a storage box arranged and fixed on the back side of the pachinko machine. The storage box has a structure for simply supporting and storing the circuit board. [Problems to be Solved by the Invention] However, in view of the actual situation of the pachinko machine, it is not sufficient to simply store the circuit board on which the electronic components are mounted in the box. In other words, many wires must be connected to the circuit board,
This connection is performed by inserting a connector to which a number of electric wires are connected into a connector on the circuit board side. At the time of this insertion, a large force is applied to the circuit board, but this force causes the circuit board to bend or break, resulting in poor electrical connection between the wiring pattern on the circuit board and the electronic components. In addition, there is a problem that the wiring pattern on the circuit board is disconnected in some cases. The present invention has been made in view of the above-described problems, and its purpose is to prevent an accident such as a failure of electrical connection on a circuit board or a disconnection even when a force is applied to a stored circuit board. An object of the present invention is to provide a box for storing a circuit board in a pachinko machine that can surely prevent the occurrence. Means for Solving the Problems In order to achieve the above object, a circuit board storage box according to the present invention will be described with reference to the drawings corresponding to the embodiments. A main body 11 that is disposed and fixed on the back side of the pachinko machine and supports the entirety of one circuit board 20 having substantially the same shape as the bottom surface by floating the entire circuit board 20 from the bottom surface;
A circuit board 20 which covers a portion on which electronic components are mounted except for a connector portion 21 which is narrowly unevenly distributed on one side of a circuit board 20 which is floated and supported in the main body 11.
When the connector 23 provided at the end of the wiring 22 is vertically pressed and connected to the connector portion 21 exposed on one side, the back surface of the connector portion 21 of the circuit board 20 is supported so that the circuit board 20 is not deformed. Support projections as supporting parts
12 is provided on the main body 11, and an air vent hole 13c is provided on a side surface thereof in a state where the main body 11 and the lid 13 are assembled. The circuit board 20 is housed in a space formed by the main body 11 and the lid 13, as shown in FIG.
In particular, the back surface of the portion where the connector portion 21 is formed can be supported by the support projections 12 as support portions on the main body 11. Accordingly, even when a force is applied to the connector portion 21 on the circuit board 20 side when the connector 23 to which a large number of wirings 22 are connected is inserted into the connector portion 21, the circuit board 20 is still supported. Since the circuit board 20 is supported, the circuit board 20 does not bend or break, and an accident such as a failure in electrical connection on the circuit board 20 or disconnection can be reliably prevented. Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a circuit board storage box 10 according to the present invention.
The circuit board storage box 10 mainly includes a main body 11 and a lid 13 fitted and fixed to the main body 11, as shown in FIG.

At four slightly inside corners on the top 11, mounting bosses 11a for projecting and fixing one circuit board 20 having substantially the same shape as the bottom surface of the main body 11 are projected. In the present embodiment, each support projection 12 is formed integrally with the main body 11,
It may be formed separately and provided, or any structure may be used as long as the structure supports the shape. The lid 13 is, as shown in FIGS.
And a storage portion suitable for storing various electronic components mounted thereon, and covers a portion where the electronic components are mounted except for the connector portion 21 which is unevenly distributed on one side of the circuit board 20. The lid 13 includes a plate-shaped portion 13a and an opening window 13b that opens above the connector portion 21. In the illustrated embodiment, an air vent hole 13c is formed on the upper surface of the lid 13. Further, by extending the left and right side walls of the lid 13 downward in the figure, the extended portion serves as a protective wall 14, as shown in FIGS. These protective walls 14, as shown in FIG.
To protect the connector portion formed by integrating the connector portion 21 on the side and the connector 23 on the wiring 22 side,
The connector is large enough to cover the left and right sides of the connector. As shown in FIG. 1 and FIG.
A storage recess 15 is formed on the right side of FIG. The storage recess 15 is formed by forming a step 15a on the right side portion of the lid 13 and projecting the protrusions 15b on both upper and lower ends of the step 15a. This storage recess 15
Can be formed as a vertically continuous groove, but as in the present embodiment, the stepped portion 15a and the upper and lower protrusions 15b provide a gap between the two protrusions 15b for inserting a finger or the like. It can be formed so that work such as taking out the wiring 22 in the storage recess 15 can be performed more favorably. In the circuit board storage box 10 configured as described above, the circuit board 20 is stored in the space formed by the main body 11 and the lid 13, as shown in FIG.
In particular, the back surface of the portion where the connector portion 21 is formed can be supported by the supporting projections 12 on the main body 11. In other words, even if the connector portion 21 of the circuit board 20 has been floating from the support projection 12, it can be supported by the support projection 12 due to the presence of the support projection 12 below it. It is. As a result, when a connector 23 to which a large number of wirings 22 are connected is inserted into the connector portion 21 in the vertical direction, the connector portion on the circuit board 20 side
