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 floppy disk drive which is used by being attached to a host device.

[0002]

2. Description of the Related Art FIG. 3 is a side view showing an example of a conventional floppy disk drive, and FIG. 4 is a sectional view showing details of a main part of the example of FIG.

[0003] A conventional floppy disk drive used by being attached to a host device, as shown in FIGS. 3 and 4, has a holder 1 provided with a screw hole 13 for attachment to the host device.
The guide holes 18 corresponding to the guide bosses 19 provided on the frame 11
Is provided on the holder 12, the guide boss 19 is fitted into the guide hole 18, the relative position between the frame 11 and the holder 12 is determined, and the screw 13 is used to fix both.

[0004]

When the conventional floppy disk drive as described above is mounted on a host device,
The main unit of the floppy disk device is guided by the panel of the host device, while the holder is fixed to the mounting hole of the mounting bracket with screws. However, if the mounting hole of the mounting bracket has poor flatness, the main unit of the floppy disk device There is a problem in that distortion is caused by the panel of the apparatus, which affects the positioning accuracy of the magnetic head.

[0005]

According to the present invention, there is provided a floppy disk drive comprising: a holder having a convex portion provided with a screw hole for mounting to a host device; a frame having a hole into which the convex portion of the holder is fitted; An elastic member mounted between the convex portion of the holder and the hole of the frame; and rotatably connecting the frame and the holder with one screw.

[0006]

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

FIG. 1 is a sectional view showing details of a main part of the embodiment of FIG. 2, and FIG. 2 is a side view showing an embodiment of the present invention.

In FIG. 1 and FIG. 2, the holder 2 is connected to the frame 1 by a single stepped screw 7 at the center, and the holder 2 can rotate freely about the screw 7 with respect to the frame 1. Can be. Protrusions 4 formed by burring are provided at both ends of the holder 2, and the protrusions 4 are provided with screw holes 3 for attaching the floppy disk device to a host device. A cylindrical elastic member 5 with a flange is mounted on the outer periphery of the convex portion 4. The inner diameter of the elastic member 5 is equal to the outer diameter of the projection 4, and the outer diameter is equal to the inner diameter of the hole 6 provided in the frame 1. Therefore, the holder 2 is attached to the frame 1 via the elastic member 5.

When the floppy disk device constructed as described above is mounted on a host device, it is screwed through the screw hole 3. At this time, if the flatness of the screw hole 3 is poor,
The holder 2 is deformed, but the distortion of the deformation is not transmitted to the frame 1 because it is absorbed by the elastic member 5. For this reason, no distortion occurs in the main body of the floppy disk device, and therefore, there is no influence on the positioning accuracy of the magnetic head.

[0010]

As described above, in the floppy disk drive of the present invention, the elastic member is interposed between the holder and the frame, and the frame and the holder are rotatably connected by one screw. Even when the holder is deformed,
This has the effect of preventing the distortion of the deformation from being absorbed by the elastic member and being transmitted to the frame. Therefore, it is possible to prevent the occurrence of distortion in the main body of the floppy disk device, thereby ensuring the positioning accuracy of the magnetic head. There is an effect that can be.
