BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for a standing substrate, which stands on a substrate disposed below a top plate of a synthetic resin top case, and fixes the standing substrate. About.

[0002]

2. Description of the Related Art Conventionally, this type of standing substrate fixing structure has
For example, as shown in FIG. 3, a rib 11 is provided on the jack board 10, and a substrate 12 is provided in a recess formed in the rib 11.
The standing substrate 13 was fixed on the substrate 12 by inserting the edge of the standing substrate 13 erected above and sandwiching the edge with the rib 11. However, this conventional standing board fixing structure has a problem in that it cannot be fixed unless the standing board 13 is located near the jack board 10.

[0003] As shown in FIG. 4, an accessory 15 such as a resin component is attached to the upper surface of an electronic component 14 near a standing board 13 erected on a board 12.
5 to fix the standing board 13, or as shown in FIG. 5, an accessory 17 such as a cushion material is disposed between the standing board 13 and the top plate 16 of the top case to fix the standing board 12. I was According to this, accessory parts 15 such as resin parts and cushioning material for fixing the standing substrate 12,
17 is required, so that there is a problem that the cost increases.

A conventional structure for fixing a sub-printed board is disclosed in Japanese Utility Model Laid-Open No. 3-101586. This conventional sub-printing board fixing structure is shown in FIG.
As shown in the figure, a sub-printed board 102 is suspended from the printed board 101 inside the surface board 103 covering the front face of the printed board 101 having a circuit structure, and is connected to the printed board 101. Covering short surface 104
And a top plate 105 which is formed by bending one side 141 of the surface portion 104 rearward and is parallel to the printed board 101, and a surface board 103 fixed to the printed board 101, and a short printed board 101 Edge 122 and its opposite edge 12
3 is a sub-printed board 102 provided with a projection 108.
The top plate 105 of the surface plate 103 and the printed board 1
01, the projection 108 is inserted and fixed in an insertion hole 107 provided at a position corresponding to the projection 108 of the printed board 101 and the top plate 105.

However, this conventional structure for fixing a sub-printed board has a structure in which
Since the insertion hole 107 for inserting the 08 is formed, a top plate 105 dedicated to the sub-printed board 102 is required, and there is a problem that this top plate 105 cannot be applied to other purposes.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and not only fixes a standing board at a limited location on the board, but also enlarges the range of standing the standing board on the board. It is an object of the present invention to provide a standing board fixing structure that can easily and securely fix these standing boards, and does not require any accessories for fixing the standing boards, thereby reducing costs. The purpose is.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a standing substrate is erected on a substrate disposed below a top plate of a synthetic resin top case. A standing board fixing structure for fixing a lever standing board, wherein a rib for holding the standing board is provided on a top plate of the top case.
The invention according to claim 2 is characterized in that a recess is formed in the rib so as to sandwich the upper end of the standing substrate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a standing board fixing structure according to an embodiment of the present invention. FIG. 1 is a sectional view showing a standing substrate fixing structure according to an embodiment of the present invention, and FIG. 2 is a plan view showing an arrangement state of the standing substrate in the standing substrate fixing structure of the embodiment.

The fixing structure of the standing substrate according to the present embodiment is shown in FIG.
As shown in FIG. 1, a substrate 2 is disposed below a top plate 1 of a synthetic resin top case, and a substrate 3 stands on the substrate 2. And on the top plate 1 of this top case,
A rib 4 for holding the standing substrate 3 erected on the substrate 2 is provided integrally. Further, the rib 4 is formed with a concave portion 5 having a shape sandwiching the upper end of the standing substrate 3.

In the standing substrate fixing structure of the present embodiment, the upper end of the standing substrate 3 erected on the substrate 2 is provided with a rib 4 integrally provided on the lower surface side of the top plate 1 of the synthetic resin top case. The upper end of the standing substrate 3 is sandwiched between the concave portions 5 of the ribs 4, and the standing substrate 3 is held and fixed on the substrate 2. According to the standing substrate fixing structure of the present embodiment, the standing substrate 3 erected on the substrate 2 is held and fixed by the ribs 4 integrally provided on the lower surface side of the top plate 1 of the synthetic resin top case. Therefore, not only can the fixed standing substrate on a limited portion on the substrate 2 be fixed, but also the range of standing the standing substrate 3 on the substrate 2 can be expanded (see FIG. 2). Can be easily and reliably fixed.

Moreover, no additional parts for fixing the standing board 3 are required, and the cost can be reduced. Furthermore, rib 4
Since the upper end of the standing substrate 3 is sandwiched by the concave portions 5 provided in the substrate 2, the standing substrate 3 on the substrate 2 can be securely held and fixed in a state where the standing substrate 3 is accurately positioned.

[0012]

As described above, according to the first aspect of the present invention, the standing substrate standing on the substrate is held by the rib integrally provided on the lower surface of the synthetic resin top plate. Since the fixed substrate is fixed, not only the fixed standing substrate on a limited portion on the substrate can be fixed, but also the range in which the standing substrate can be set on the substrate can be expanded, and these standing substrates can be easily and reliably fixed. Can be fixed.
In addition, there is no need for an accessory component for fixing the standing board, so that the cost can be reduced.

According to the second aspect of the present invention, since the upper end of the standing substrate can be held and held by the concave portion provided in the rib, the standing substrate can be accurately positioned.
The standing substrate on the substrate can be reliably held and fixed.
