Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a support structure for a unit cabinet in a device such as a disk device that incorporates a unit susceptible to vibration.

<Prior art> In conventional equipment that incorporates vibration-sensitive units, the vibration-sensitive unit cabinet is also firmly fixed to the mounting member of the equipment body using screws, making it difficult for the unit to be easily penetrated from the outside. This has the disadvantage that it directly picks up vibrations, causing malfunctions. In particular, floppy disk drive units have a major drawback in that vertical vibrations can damage the head, the guide rod supporting the head, the media, etc.

<Purpose of the invention> The present invention was made in view of these conventional drawbacks, and involves attaching a bush made of an elastic member to a unit cabinet that is susceptible to vibration, and fixing it to the cabinet mounting member of the main body of the device. It is an object of the present invention to provide a support structure for a cabinet which can sufficiently buffer external vibrations and allow the entire cabinet to be moved to some extent in the vertical direction.

<Embodiment> A support structure for a cabinet, which is an embodiment of the present invention, will be described below based on the drawings.

FIG. 1 shows a floppy disk drive unit as a cabinet, 1 is the cabinet of the drive unit, 2 is a floppy disk insertion slot, 3 is a screw hole provided on the bottom of the cabinet, Reference numerals 4 and 4 indicate screw holes provided on both sides of the cabinet.

FIG. 2 is a diagram showing parts used when fixing the cabinet 1 to a cabinet mounting member. Reference numeral 5 denotes a bush made of an elastic member, which is cylindrical in shape as shown in the figure, with a hole 6 passing through the center and a groove 7 in the center of the side peripheral surface. Further, 8 is a screw whose shape is as shown in the figure, and includes a portion 9 through which the hole 6 of the bush 5 is inserted when screwing, and a threaded portion 10 at its tip.

FIG. 3 is a perspective view showing the cabinet mounting member 11 that accommodates the cabinet body. 1 in the diagram
Reference numerals 2 and 12 denote bushing mounting holes corresponding to the screw fixing holes 3 of the cabinet 1, and as shown in the figure, the bushing fitting hole and the locking hole into which the bushing groove 7 is engaged are connected. . Also 13,13
are vertically elongated holes corresponding to screw holes 4 provided on both sides of the cabinet 1.

To attach the cabinet 1 to the cabinet mounting member 11, insert the screw 8 into the hole 6 of the bush 5.
After inserting the screw into the screw hole 3 provided on the bottom of the cabinet 1. Next, after the bush 5 is fitted into the bush fitting hole 12 of the cabinet mounting member 11, the bush 5 is slid in the direction of the locking hole connected to the groove 7 of the bush 5 and fixed. In this state, the screw holes 4 provided on both sides of the cabinet 1 are aligned with the elongated holes 13 of the cabinet attachment member 11. Therefore, by attaching the screw 8 from the outside of the cabinet attachment member 11 to the screw fixing hole 4 through the elongated hole 13, it can be fixed with flexibility in the vertical direction.

In particular, in such a support structure, the bush 5 is inserted into the screw 8 and attached to the cabinet 1, and the bush 5 is inserted and slid into the cabinet mounting member 11, so that the bush 5 is inserted between the cabinet 1 and the cabinet mounting member 11. Furthermore, since the screwed parts of both side pieces are assembled with a degree of freedom in the vertical direction, vibrations in the vertical direction from the outside can be sufficiently damped. Further, vibrations in the horizontal direction are also damped by the bushing 5.

Furthermore, since such a vibration isolator is constructed by simply attaching screws, it is easy to assemble and has excellent serviceability.

In the above embodiment, the bush 5 is provided on the bottom side of the cabinet and the mounting member, and the long hole 13 is provided on the side surface side, but the long hole 13 is provided on the bottom side,
The configuration may be such that a bush 5 is provided on the side surface.

<Effects of the invention> As mentioned above, the cabinet support structure of the invention has the following effects:
A plurality of cylindrical bushes made of elastic members having grooves on the circumferential surface are attached to the bottom of the unit cabinet, while a cross-sectional cabinet mounting member is provided inside the equipment in which the unit cabinet is housed. A mounting hole consisting of a bushing insertion hole and a locking hole connected to the hole and engaged with a groove of the bushing is formed on the bottom surface of the cabinet at a position corresponding to the bushing. A long hole for inserting a mounting screw is provided in one part to provide freedom in the vertical direction and prevent the bushing from coming off in the horizontal direction, so that the bushing installed in the cabinet can be inserted into the bushing insertion hole. The bushing is inserted between the cabinet and the cabinet mounting member, and the bushing is inserted into the locking hole and fixed by screwing to both sides of the cabinet through the elongated hole of the mounting member. Because of this, external vibrations can be sufficiently buffered. Furthermore, since the supporting structure of such a cabinet is assembled only by screwing, assembly is easy and serviceability is also excellent.

Claims (1)

[Scope of Claim for Utility Model Registration] In a device that incorporates a unit that is susceptible to vibrations, such as a disk device, a plurality of cylindrical bushes made of an elastic member having grooves on the circumferential surface are provided on the bottom surface of the unit cabinet. On the other hand, on the bottom surface of the cross-sectional cabinet mounting member provided in the equipment in which the unit cabinet is housed, a bushing insertion hole is provided at a position corresponding to the bushing, and a bushing groove is connected to the hole. At the same time, long holes for inserting attachment screws are provided on both sides of the cabinet attachment member, so that the bush attached to the cabinet can be inserted into the bush. By inserting it into the fitting hole, engaging it with the locking hole, and screwing it to both sides of the cabinet through the elongated hole of the mounting member, it has some degree of freedom in the vertical direction, and the bushing in the horizontal direction. A support structure for a cabinet that is characterized by preventing the material from coming off.
