DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floppy disk drive, and more particularly to a mounting structure for a higher-level device.

[0002]

2. Description of the Related Art FIG. 4 is a side view showing an example of a conventional floppy disk drive, and FIG. 5 is a sectional view taken along the line CC of the example of FIG.

When the floppy disk device is mounted on the host device when the floppy disk device is directly fixed to the host device, a mounting hole provided in the host device and a frame constituting a housing of the floppy disk device are provided. The frame of the floppy disk device, which is structurally weak, is deformed due to misalignment with the provided screw holes or deformation of the mounting surface, affecting the inside of the floppy disk device, and the floppy disk device operates normally. 4 and 5, the conventional floppy disk device is attached to a host device via a holder 12 formed of a strip-shaped thin plate.

[0004] The holder 12 has a screw hole 13 at both ends for attaching to a host device, and a through hole 15 at the center for letting a screw portion of a screw 16 pass therethrough.
A guide hole 17 is provided between 3 and the through hole 15.

When the floppy disk drive 20 is mounted on the host device via the holder 12 constructed as described above, the guide boss 18 provided on the frame 11 is inserted into the guide hole 17 to move the holder 12 to the frame 11. The screw 16 is fixed to a screw hole 19 provided in the frame 11 by passing the screw 16 through the through hole 15.
, The holder 12 is screwed into a mounting hole provided in a mounting bracket of the host device.

[0006]

In the above-mentioned conventional means for mounting a floppy disk device to a higher-level device, if the relative position between the screw hole of the holder and the mounting hole of the mounting bracket of the higher-level device is shifted, the floppy disk is mounted. There is a disadvantage that the frame of the disk device is deformed due to distortion. In particular, in recent thinned floppy disk drives, the effect is noticeable, and there is a problem that the positioning accuracy of the magnetic head is adversely affected.

[0007]

SUMMARY OF THE INVENTION A floppy disk drive according to the present invention has a frame and screw holes at both ends for mounting to a higher-level device. A strip-shaped thin plate provided with a bent portion bent in a “U” shape toward the frame at a lower edge near the screw hole between the screw hole and the through hole. And an elastic member interposed between the bent portion of the holder and the frame, and the holder is rotatably attached to the frame by the stepped screws.

[0008]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view taken along the line AA of the embodiment of FIG. 2, FIG. 2 is a side view showing an embodiment of the present invention, and FIG. 3 is a sectional view taken along the line BB of the embodiment of FIG. .

In FIG. 1 to FIG. 3, the holder 2 has screw holes 3 at both ends for mounting to a host device, and a through hole for passing the screw portion of the stepped screw 6 and the step portion at the center. have. Screw hole 3 between screw hole 3 and through hole
Is provided with a bent portion 4 which is bent in a "U" shape toward the frame 1 at a lower edge portion in the vicinity of.

The holder 2 has a step portion of the stepped screw 6 and a step portion penetrated through a central through hole, and a screw portion of the stepped screw 6 is fixed to a screw hole 9 provided in the frame 1 by screwing. At this time, since there is a play gap between the through hole of the holder 2 and the step portion of the stepped screw 6, the holder 2 can freely rotate around the stepped screw 6. Can be.

Between the inside of the bent portion 4 and the frame 1,
A cubic elastic member 5 is mounted. Therefore, the holder 2 contacts the frame 1 via the elastic member 5.

When the floppy disk drive 10 is mounted on a host device via the holder 2 configured as described above,
The holder 2 is fixed to the frame 1 by the stepped screw 6,
The holder 2 is screw-fixed to the mounting hole provided in the mounting bracket of the host device via the screw hole 3 while positioning the two elastic members 5 so as to substantially uniformly contact the frame 1.

Thus, even if the relative position between the screw hole of the holder and the mounting hole of the mounting bracket of the host device is shifted, the distortion is absorbed by the elastic member, so that the deformation of the frame is prevented. Also, when a drop impact is applied to the host device, the drop impact is not transmitted to the floppy disk device because the drop impact is absorbed by the elastic member.

[0015]

As described above, in the floppy disk drive according to the present invention, the center of the holder is rotatably mounted on the frame, and a bent portion is provided on the lower edge of the holder. By interposing an elastic member, even if the relative position between the screw hole of the holder and the mounting hole of the mounting bracket of the upper device is shifted, the distortion can be absorbed by the elastic member to prevent the deformation of the frame. Therefore, there is an effect that a highly reliable floppy disk device which ensures the positioning accuracy of the magnetic head can be obtained. Also, when a drop impact is applied to the host device, the drop impact can be absorbed by the elastic member,
There is also an effect that the reliability of the floppy disk device can be improved.
