<FIRST EMBODIMENT>

In FIGS. 1 to 3, reference number 1 denotes a circuit board that is fixed to a casing 3, with being separated from inner walls thereof, through holder portions 5 disposed at four corners of the casing 3 of an electronic equipment 100. In order to fix the circuit board 1 to the holder portions 5, a fixing means such as a screw 5a or the like is used. The fixing means is not limited to the screw 5a and a clip or the like may be used. Each of electronic parts 7 for controlling the electronic equipment 100 is mounted and wired on the circuit board 1. An opening portion 9 having a square shape is provided at the center of the circuit board 1 and a hard disk drive 13 (hereinafter abbreviated as an “HDD”) is held in the space of the casing 3 through a holding member 11.

The holding member 11 is formed approximately into a loop having a square shape with a cutout area where a flexible printed circuit board 17 (hereinafter abbreviated as an “FPC”) for electrically connecting a connector 15 on the circuit board 1 to the HDD 13 is disposed. Since the FPC 17 connects the HDD 13 to the connector 15 with an allowance so that the FPC 17 may be deformed, even if the HDD 13 is displaced due to a shock or a shake, the electrical connection between the HDD 13 and the connector 15 can be secured.

As shown in FIG. 2, the cross sectional shape of the holding member 11 along the B-B line is a rectangle. In an inner circumference of the holding member 11, there is formed a groove 11a almost all the way around for holding the HDD 13 by fitting therein. In the groove 11a, the HDD 13 is fitted almost all the way around to be held on the outer circumference thereof by the holding member 11. In an outer circumference of the holding member 11, there is formed a groove 11b almost all the way around in which edges of the opening portion 9 of the circuit board 1 are fitted to hold the holding member 11. Accordingly, it becomes possible to hold the HDD 13 at the opening portion 9 of the circuit board 1 through the holding member 11 without touching inner wall of the casing 3.

Incidentally, in FIGS. 2 and 3, the HDD 13 may be held such that both of the upper surface 11c (upper side in FIG. 2) and the lower surface 11d (lower side in FIG. 2) of the holding member 11 are separated from the inner wall of the casing 3 or such that at least one surface of the upper surface 11c and the lower surface 11d of the holding member 11 makes contact with the inner wall of the casing 3. In this manner, the electronic equipment equipped with a memory device which is vulnerable to a shock and a shake is constructed.

In the first embodiment of the present invention, the holding member 11 is made of an elastic body (a gel-type material such as rubber, urethane resin, silicone resin, or the like) to absorb a shock and a shake from outside of the casing 3 in order to protect the HDD 13 from a malfunction or a breakdown. Moreover, since the HDD 13 is held at the opening portion 9 of the circuit board 1 through the holding member 11, the whole thickness of the electronic equipment 100 including the circuit board 1 and the HDD 13 can be thinner than that of a conventional construction that the circuit board 1 is disposed in the vicinity of one side of the HDD 13.

<VARIATION>

Then, a variation of the present invention is explained with reference to FIGS. 4 through 6.

The variation is different from the first embodiment in that the opening portion is formed by cutting out at least one side of the circuit board, so that it is explained with attaching the same reference numbers to the similar constructions to the first embodiment.

In FIGS. 4 to 6, reference number 201 denotes a circuit board that is fixed to a casing 3, with being separated from inner walls thereof, through holder portions 5 disposed at four corners of the casing 3 of an electronic equipment 200. In order to fix the circuit board 201 to the holder portions 5, a fixing means such as a screw 5a or the like is used. The fixing means is not limited to the screw 5a and a clip or the like may be used. Each of electronic parts 7 for controlling the electronic equipment 200 is mounted and wired on the circuit board 201. An opening portion 209 having a square shape is provided at the lower side portion (lower side in FIG. 4) of the circuit board 201 and a hard disk drive 13 (hereinafter abbreviated as an “HDD”) is held in the space of the casing 3 through a holding member 11.

The holding member 11 is formed approximately into a loop having a square shape with a cutout area where a flexible printed circuit board 17 (hereinafter abbreviated as an “FPC”) for electrically connecting a connector 15 on the circuit board 201 to the HDD 13 is disposed. Since the FPC 17 connects the HDD 13 to the connector 15 with an allowance so that the FPC 17 may be deformed, even if the HDD 13 is displaced due to a shock or a shake, the electrical connection between the HDD 13 and the connector 15 can be secured.

As shown in FIG. 5, the cross sectional shape of the holding member 11 along the B-B line is substantially rectangular. In an inner circumference of the holding member 11, there is formed a groove 11a almost all the way around for holding the HDD 13 by fitting therein. In the groove 11a, the HDD 13 is fitted almost all the way around to be held on the outer circumference by the holding member 11. In an outer circumference of the holding member 11, there is formed a groove 11b in which edges of the opening portion 209 of the circuit board 201 are fitted to hold the holding member 11 on three sides except one side 11e where the holing member 11 makes contact with the inner wall of the casing 3. Moreover, the side wall portion lie of the outer circumference of the holding member 11 makes contact with the inner wall of the casing 3. Accordingly, it becomes possible to hold the HDD 13 at the opening portion 209 of the circuit board 201 by means of the holding member 11 and by making the side wall portion 11e of the outer circumference of the holding member 11 contact with the inner wall of the casing 3. In this manner, the electronic equipment equipped with a memory device which is vulnerable to a shock and a shake is constructed. Incidentally, the opening portion 209 formed on the circuit board 201 may be formed on any other side of the circuit board 201. In addition, the cutout length L (see FIG. 4) may be suitably changed in accordance with the corresponding side length of the HDD 13.

Incidentally, in FIGS. 5 and 6, similar to the first embodiment, the HDD 13 may be held such that both of the upper surface 11c (upper side in FIG. 5) and the lower surface 11d (lower side in FIG. 5) of the holding member 11 are separated from the inner wall of the casing 3 or such that at least one surface of the upper surface 11c and the lower surface 11d of the holding member 11 makes contact with the inner wall of the casing 3.

In the variation of the present invention, the holding member 11 is made of an elastic body (a gel-type material such as rubber, urethane resin, silicone resin, or the like) to absorb a shock and a shake from outside of the casing 3 in order to protect the HDD 13 from a malfunction or a breakdown. Moreover, since the HDD 13 is held at the opening portion 209 of the circuit board 201 through the holding member 11, the whole thickness of the electronic equipment 200 including the circuit board 201 and the HDD 13 can be thinner than that of a conventional construction that the circuit board 201 is disposed in the vicinity of one side of the HDD 13.

In the first embodiment and the variation of the present invention, although the explanation is made in a case that the memory device to be protected is an HDD 13, it is not limited to the HDD 13. The present invention can be applied to hold a memory device vulnerable to a shock and a shake, such as an optical disk drive, and the like.

An electronic equipment equipped with the memory device according to the first embodiment or the variation of the present invention makes it possible to construct a portion or the whole of an equipment such as a digital camera, a digital video camera, a portable digital audio equipment, a portable MP3 equipment, a PDA equipment, a portable measuring instrument, and the like.

Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
