Is set so as to be pressed by the ceiling surface of the case lid, thereby preventing displacement and backlash of the sub printed circuit board 560 in the Z direction.
As described above, the conventional liquid crystal control printed circuit board unit selectively uses two types of sub printed circuit boards in which the shape and size of the substrate portion, the shape of the mounted CG memory, and the mounting method are different. In this case, it was necessary to prepare and use two types of dedicated cases each having a support structure suitable for each sub printed circuit board. In other words, it is necessary to use different cases depending on which sub printed circuit board is used.

Further, in the liquid crystal control printed circuit board unit 506 of FIG. 22, there is no means for regulating the backlash of the sub printed circuit board 515 in the vertical direction, and connector connection failure or dropout may occur. For this reason, there existed a problem that a cost increase and an assembly number increased.
Further, even in the liquid crystal control printed circuit board unit 506 of FIG. 23, there is no means for regulating the backlash of the sub printed circuit board 560 in the vertical direction, and the connection failure or dropout of the connector may occur. For this reason, there existed a problem that a cost increase and an assembly number increased.

At the same time, the lateral direction (X direction) position is set so that the lateral one end edge of the second sub printed circuit board 120 can be supported in the recess. In this example, the distance from the edge of the fixed connector 105 to the recess of the second support protrusion 85 is set to X1, and the distance X1 is set to substantially match the lateral dimension W2 of the second sub printed circuit board 120. (FIG. 10). The vertical distance Y1 between the two second support protrusions 85 is set to be narrower than the vertical length L2 of the second sub printed circuit board (FIG. 14).

FIG. 18A is a perspective view showing a state in which the case lid supports the first sub printed circuit board, and FIG. 19A is a front view showing the same state.
Since the CG memory 117 on the first sub-printed circuit board projects rearward (Z direction) from the board body 111, the ceiling surface of the case lid body 70 to be mounted on the case base 80 (regulated portion) The height position of the ceiling surface is selected so that 71) comes into contact (fitting support) with the top side of the CG memory 117 and regulates rattling in the Z direction (see the sectional view of FIG. 11). By using the restricting portion 71 as a recess (elongated groove) and receiving the top side of each CG memory 117, the lateral displacement of the first sub printed circuit board can be restricted via the CG memory.

Next, FIG. 18B is a perspective view showing a state in which the case lid supports the second sub printed circuit board, and FIG. 19B is a front view showing the same state.
On the other hand, when the case lid is placed on the case base 80 on the ceiling surface of the case lid 70, it abuts against the surface of the substrate body 121 of the second sub printed circuit board 120 and regulates rattling in the Z direction. Two ribs 75 are provided. In this example, the two ribs 75 are in contact with the surfaces of the two corners of the second sub printed circuit board 120 and restrict movement (backlash) in a direction perpendicular to the surface.
In addition, as shown to AA sectional drawing of FIG.19 (c), the front-end | tip part of each rib 75 is comprised in L shape and other arbitrary shapes, By this, not only the upper surface of the board | substrate body 121 but an end surface is formed. It is also possible to suppress the backlash of the second sub printed circuit board 120 in the vertical direction. A recess 75a at the top of the L-shape at the tip of the rib 75 constitutes a vertical direction movement restricting portion.
Alternatively, a rib dedicated to preventing rattling in the vertical direction different from the rib 75 may be provided so that only the end surface of the substrate body 121 is suppressed.

As described above, according to the present invention, even when the two types of sub-printed boards having different shapes and sizes of the board portions, the shapes of the mounted CG memories, and the mounting methods are selectively used, By using a common case with a support structure suitable for each sub-printed circuit board, it is not necessary to prepare two types of dedicated cases for each sub-printed circuit board, and costs and assembly costs can be reduced. it can.
Further, in the case, it is possible to reliably prevent the occurrence of poor connection by regulating the positional deviation and backlash in the horizontal direction, the vertical direction, and the direction orthogonal to the board surface of the two types of sub-printed boards.
That is, the case base and the case lid can be commonly used for any sub printed circuit board.

In the above embodiment, the liquid crystal control printed circuit board unit is cited as the printed circuit board unit 100. However, this is merely an example, and the present invention generally relates to a printed circuit board unit that detachably connects a sub printed circuit board to the main printed circuit board. Can be applied. Accordingly, it is possible to assume a memory other than the CG memory and other electronic components in general as the electronic components mounted on the sub printed circuit board.
The present invention can be applied not only to pachinko gaming machines but also to slot machines and other gaming machines and game machines having an image display device.
