Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate supporting device used for mounting a substrate on the inner surface of the casing of various equipment such as office machines.

[0002]

2. Description of the Related Art Enclosures of various machines such as office machines are constructed so that they can be divided into at least two parts in order to mount parts therein. That is, it is general that various components are mounted on a base body called a base or a case, and a cover covering these components is attached to the base body. An example thereof will be described below with reference to FIGS. 9 and 10. The case 1 includes a case 2 which is a base body having an open upper surface and a cover 3 having an open lower surface.
It is formed by combining and. A horizontal reference surface 4 for the case 2 is formed on the lower edge around the cover 3,
A panel surface 6 that is inclined with respect to the reference surface 4 is formed at the end portion on the front surface side (right side in the drawing) of the horizontal upper surface 5. The reason why the panel surface 6 is inclined is to improve the operability of the operation unit (not shown) arranged on the panel surface 6 and the visibility of the display unit (not shown).

As described above, when the operation unit and the display unit are mounted on the panel surface 6, the substrate 7 is provided for connecting the operation unit and the display unit to the circuit. In order to mount the board 7 in a narrow space, it is necessary to mount the board 7 in parallel with the panel surface 6. Therefore, a plurality of board mounting bosses 8 are vertically formed on the inner surface of the panel surface 6 and fixed through the board 7. A method of screwing the screw 9 into the board mounting boss 8 is adopted.

[0004]

In order to fix the board 7 in parallel with the panel surface 6, the axis of the board mounting boss 8 is made perpendicular to the panel surface 6 and the board 7, and the fixing screw from the direction of arrow A. 7 must be screwed together. On the other hand, when the cover 3 has a container-like shape, an undercut occurs unless the peripheral side surface of the cover 3 is greatly expanded. In addition, if the die cutting direction is set to the direction orthogonal to the reference plane 4, an undercut will occur in the board mounting boss 8. Therefore, in order to mold the cover 3, a complicated molding die having a slide core is used. However, there is a problem that the manufacturing cost becomes high.

[0005]

According to the present invention, there is provided a base body on which various parts are mounted, a reference surface abutting on the base body, and a panel surface inclined with respect to the reference surface. In addition, a cover that forms a housing of the device, a substrate that is arranged to face the inner surface of the panel substantially parallel to each other, a mounting hole having a central axis perpendicular to the reference plane at the center, A plurality of board mounting bosses integrally formed on the inner surface of the panel surface having a contact surface for supporting one surface of the board with a surface parallel to the panel surface; One side has a receiving seat centered on a through hole for passing a fixing screw screwed into the mounting hole and receiving the head of the fixing screw on a plane parallel to the reference plane. The other surface has a pressing surface that presses the substrate against the contact surface. A substrate supporting device constructed in accordance with the number of the pressing member.

[0006]

[Operation] By screwing the fixing screw, which is passed through the through hole of the holding member and the board, into the mounting hole of the board mounting boss, the board is held between the board mounting boss and the holding member in a state parallel to the panel surface. To be done. In this case, the contact surface of the board mounting boss and the pressing surface of the pressing member are inclined with respect to the axis of the fixing screw, but the axis of the mounting hole is perpendicular to the reference surface and the seat of the pressing member is Since it is parallel to the reference plane, the pressing member is brought into close contact with the substrate by the head of the fixing screw.

A through hole 19 for passing the fixing screw 9 is formed at the center of the
A receiving seat 20 for receiving the head portion 9a of the fixing screw 9 with a surface parallel to the reference surface 4 is formed on one surface, and the other surface is inclined with respect to the receiving seat 20 to form the contact surface 14. A pressing surface 21 for pressing the substrate 7 is formed, and the pressing surface 21 is formed.
At the end of each of the projections 2 fitted in the locking holes 17 of the substrate 7,
2 is formed.

In such a structure, the fixing screw 9 is passed through the through hole 19 from the receiving seat 20 side of the pressing member 18, and the projection 22 of the pressing member 18 is fitted into the locking hole 17 of the substrate 7 while the fixing screw 9 is being inserted. Is passed through the mounting hole 16 of the substrate 7 and screwed into the mounting hole 13 of the substrate mounting boss 12, so that the contact surface 14 of the substrate mounting boss 12 and the pressing member 18 are pressed while the substrate 7 is parallel to the panel surface 6. It is held between the surface 21. In this case, the contact surface 14 and the pressing surface 21 are inclined with respect to the axis of the fixing screw 9, but the axis of the mounting hole 13 is perpendicular to the reference surface 4, and the receiving seat 20 of the pressing member 18 is Since it is parallel to the reference plane 4, the pressing member 18 is brought into close contact with the substrate 7 by the head portion 9a of the fixing screw 9. In this case, the pressing member 18 is the protrusion 2
Since 2 is fitted in the locking hole 17 of the substrate 7, it is prevented from rotating even when the tightening torque of the fixing screw 9 is received. As described above, the panel surface 6 of the cover 3 is inclined with respect to the reference surface 4, but the board mounting boss 12 and the mounting hole 13 at the center thereof are perpendicular to the reference surface 4 so that the inner surface of the panel surface 6 is covered. By forming the cover 3, the cover 3 can be molded using a simple molding die having a structure in which the mold cutting direction is set to be a direction perpendicular to the reference surface 4.

As described above, when the housing 1 is flat, the cover 3 is attached to the case 2 with the reference surface 4 being substantially horizontal, but in the case of a device having the cover 3 on the side surface, As shown in FIG. 6, the cover 3 may be attached to another base with the reference surface 4 standing upright.

The cover is not limited to the cover 3 having the shape as shown in the above-mentioned embodiment, but as shown in FIGS. 7 and 8, the panel inclined with respect to the reference plane 4 contacting the base body. The present invention can be applied to the covers 23 and 24 having the surface 6. That is, in any of the cases shown in FIGS. 6 to 8, the contact surface 14 parallel to the panel surface 6 is provided.
The substrate mounting boss 12 having the tip at the end can be formed on the inner surface of the panel surface 6 so as to be perpendicular to the reference surface 4. Further, the board provided along the inner side of the panel surface 6 is not limited to the circuit board, but is applicable as a board supporting device including a mounting plate for a mechanical component.
