As shown in FIG. 4, the base box 10 is attached to a winning ball set cover 3 provided on the back side of the game board 2 in a pachinko machine P which is a kind of a game machine, for example. The base box 10 is a combination of a transparent box base 11 made of synthetic resin and a transparent box cover 12 also made of synthetic resin, and is an assembly of electronic components (not shown) such as a built-in ROM. The base 4 is housed inside.

The box base 11 has a rectangular plate 11a, ribs 11b (see FIG. 5) protruding from the upper surface of the plate 11a and serving as a mounting base for a printed board 4a described later, and two adjacent sides of the plate 11a. Auxiliary side plates 11c...
Are mounted on the upper and lower two sides of the cover 3 and engage with the mounting portions of the winning ball collecting cover 3.

On the other hand, the box cover 12 has a form in which an upper surface and four peripheral side surfaces are surrounded by an upper plate 12a and peripheral side plates 12b to 12e, and is attached to two peripheral side plates 12d and 12e by an auxiliary side plate 11c of the box base 11. The recessed portion 12f to be fitted is formed, and the step portion 5 is formed on the other one of the peripheral side plates 12b at a position which is perpendicular to the box base 11 side. The step board 5 has a control board 4 to be described later.
A plurality of insertion ports 5a are formed corresponding to the shape, number and arrangement of the connectors 4b.

As shown in FIGS. 1 to 3, the step portion 5 has a connector opening 5b formed in the box cover 12.
And a transparent plate-like cover member 5c made of synthetic resin for closing the connector opening 5b from the inside. The insertion hole 5a is provided in the cover member 5c. The cover member 5c is provided with an engagement step 5d on the outer periphery, and the periphery of the connector opening 5b is engaged with the engagement step 5d.

As described above, the insertion port 5a is connected to the box cover 1
The base box 10, which is provided on the cover member 5c separate from the base member 2, can be used as a measure to reduce costs because changes in the shape, the number, the arrangement, and the like of the connectors 4b can be handled by replacing only the cover member 5c. High in nature. Note that paragraph 0016 has a more detailed description on this point.

The control board 4 includes a printed board 4a,
An electronic component such as a built-in ROM and a CPU and a connector 4b for connection are attached. There are a plurality of connectors 4b of different types or the same type, which are arranged on one side of the printed circuit board 4a. As described above, all the connectors 4b correspond to the respective insertion ports 5a of the box cover 12.

Next, a method of assembling the base box 10 will be described. First, the control board 4 is placed on the rib 11b of the box base 11, as shown in FIG. Next, the cover member 5 is placed on the printed circuit board 4a of the control board 4.
c to cover around the connector 4b. Next, the box cover 12 is put on the box base 11 while fitting the auxiliary side plate 11c and the recess 12f. Then, screws (not shown) are passed through the mounting holes 4c of the printed circuit board 4a from the back side of the box base 11.
Into the female screw (not shown) on the box cover 12 side and tighten it. If necessary, seal the joint between the box base 11 and the box cover 12 (attach a sealing seal or attach a sealing tool). Etc.). At this time, as shown in FIG. 2, the cover member 5c is locked so that the outer peripheral engagement step 5d is sandwiched between the periphery of the connector opening 5b and the printed circuit board 4a. The cover member 5
At the junction between the connector c and the connector opening 5b, the engaging step 5d and the peripheral edge of the connector opening 5b are engaged to form an L-shape, so that a foreign substance cannot be inserted. Of course, as means for achieving the purpose of preventing such foreign matter insertion,
The joining form of the engaging step portion 5d and the connector opening 5b is not limited to the structure shown in the drawing, and the more complicated the incorporation, the higher the security effect is obtained.

Since the connector 4b of the base box 10 projects outside the box cover 12, the connector Y of the relay cable X can be freely attached and detached without removing the box cover 12 one by one. In addition, since the printed circuit board 4a around the connector 4b is not exposed to the outside of the box cover 12, the printed circuit board 4a cannot be directly touched, so that there is no gap in the printed circuit board 4a for performing illegal processing. If the size (depth) of the step portion 5 is set so that the connector 4b of the control board 4 is completely accommodated, the connector 4b is not bulky and a plurality of board boxes 10 are stacked for transportation. However, there is no possibility that the pins of the connector 4b are deformed (bent or fall). In particular, if shoulders 50 are provided at one or both ends of the step portion 5 of the box cover 12 as shown in the figure, even if the pins of the connector 4b are exposed to the outside, they may cause deformation. The risk of receiving external force decreases. Also, more preferably,
As shown by the two-dot chain line in FIG.
If a 0 is protruded to guard the pins of the connector 4b, thorough safety measures for the connector 4b are ensured.

Although the present invention has been described with reference to the embodiment, the present invention is not limited to the above embodiment. For example, in the embodiment, the step 5 is formed by closing the connector opening 5b with the cover member 5c, but the cover member 5c may be formed integrally with the box cover 12 as shown in FIG. However, the structure shown in FIG. 5 has the following disadvantages. That is, the shape, the number, the arrangement, etc. of the connectors 4b may be changed according to the game content. In such a case, in the case of FIG. Everything needs to be remade. For this reason, costs such as a mold cost are increased. On the other hand, as in the embodiment, for a gaming machine having a box base attached to the gaming machine side, a box cover covering the box base, and a control board in which electronic components and connectors for connection are mounted on a printed circuit board. In the base box, a connector opening is formed in the box cover and the connector opening is closed with a cover member, and the cover member has a shape corresponding to the connector of the control board and substantially matching the external shape of the connector. A base box that forms an insertion port and allows the connector of the control board to protrude outside the box cover through the insertion port. "
Thus, even if the shape, the number, the arrangement, etc. of the connectors 4b are changed, it is possible to cope with the change only by the cover member 5c, so that the cost such as a mold cost can be greatly reduced.

[0017]

According to the base box of the present invention, since the connector of the control base projects outside the box cover,
The relay cable can be freely attached and detached without removing the box cover. Therefore, when attaching and detaching the base box to and from the gaming machine, the work can be done by removing the relay cable,
