Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electronic device having a storage drive unit therein.

(Prior Art) A conventional device of this kind has a front case and a shelf plate for loading upper stage mounted items (storage device drive unit, for example, a floppy disk drive unit, etc.), which have separate structures, and each has a bottom case. The upper case was fastened with screws, etc., and the upper case was further fixed with decorative screws, etc.

(Problems to be solved by the invention) Due to the above-mentioned circumstances, with conventional devices, the disassembly and assembly work when assembling or repairing the device involves a lot of screw tightening work and is complicated. However, this method had the disadvantage of increasing product costs.

The present invention eliminates the above drawbacks,
The purpose is to facilitate assembly or disassembly work, and at the same time to reduce product costs by simplifying the structure.

(Means for Solving the Problems) The present invention provides an electronic device equipped with a storage drive unit 1, which includes: a shelf 5 surrounding the unit 1; and a rotatable first shelf integrally fixed to the shelf 5. a second case 3 rotatably connected to the first case 2 and provided at the bottom of the electronic device; and a second case 3 formed to rise from the bottom case 3 to a side surface of the unit 1. The angle 6, the third case 4 provided on the upper part of the electronic device so as to surround the unit outside the angle 6, and the shield 5, the angle 6, and the third case 4 respectively correspond to each other. It is characterized by comprising a fixing means 8 for integrally fixing these through a through hole provided at a position.

(Embodiment) FIG. 1 is an embodiment of the present invention, and is an external view of an electronic device that incorporates two floppy disk drive units as an example of an upper stage package (storage device drive unit). 1 is a floppy disk drive unit (hereinafter abbreviated as FDD unit), 2 is a front case (first case), 3 is a bottom case (second case), and 4 is an upper case (third case).
Fig. 2 shows the internal structure of the electronic device shown in Fig. 1, Fig. 3 is a sectional view taken along line A-A' in Fig. 2, and Fig. 4 is a diagram showing the state during assembly. can be,
The internal structure will be explained below with reference to these figures.

The shelf 5 is integrated with the front case (first case) 2 by screw fastening, and the FDD unit 1
Load. The lower end 2-a of the front case (first case) 2 and the front end 3-a of the bottom case (second case) 3 have a claw structure that engages with each other. The first case) 2 has a simple rotating structure around the claw structure with respect to the bottom case (second case) 3. Angles 6 are fixed to both sides of the bottom case (second case) 3 with screws via a shield plate 10, and the shoulder shape of the angles 6 supports both sides of the shield 5 and allows for positional adjustment. make a decision. The shield 5 has caulking nuts 5-a on both sides, and through holes are provided at corresponding positions on both sides of the angle 6 and the upper case (third case) 4. Means) 8 makes it possible for three parties to enter into an agreement at the same time. The angle 6 is the top case (third case) 4, the bottom case (second case) 3,
It exists as an intermediary when fixing Shelf 5, and at the same time has the role of establishing electrical continuity between the three parties. Using a metal plate with conductive plating on the surface of the angle 6, it is possible to conduct between the inner surface around the through hole on both sides of the upper case (third case) 4 and the outer surface around the caulking nut on both sides of the shield 5. By performing this process, it is possible to obtain complete electrical conduction between the three parties through the cosmetic screw (fixing means) 8, and further, through the angle 6, the bottom case (second case) 3 Reliable conduction can also be obtained with the shield plate 10 laid down.

Furthermore, although the above embodiment has been described using two floppy disk drive units as an example of the mounted object, the present invention is not limited to this, and for example, a magnetic disk device can also be considered as the mounted object.

(Effects) As explained above, the shelf 5 on which the upper stage mounted items (storage drive unit) is loaded and the front case (first case) 2 are integrated, and the lower end of the front case (first case) 2 and the front case (first case) 2 are integrated. They are fixed only by the claw structure at the front end of the bottom case and the decorative screws (fixing means) 8 used to fix the top case (third case) 4. Compared to the method of fastening the front case and upper case separately after tightening the front case and the like, it is possible to significantly reduce the number of man-hours required. In particular, when repairing equipment, all you have to do is remove the cosmetic screw (fixing means) 8.
Precase (first case) 2 and Shelf 5
can be easily rotated around the claw part and removed, making it possible to easily see the entire printed circuit board 9 etc. located at the bottom, speeding up the work,
This has the advantage of greatly reducing problems caused by forgetting to tighten screws, etc.

Further, in the present application, for example, as shown in FIG. 3, the angle 6 is shaped to support the shelf 5, so the contact area with each other is large, and therefore electrical continuity is good. Furthermore, the angle 6 plays the role of supporting the shield 5 and at the same time ensuring electrical continuity, and by having one component fulfill multiple roles, the number of components can be reduced.
