[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FD drive, and more particularly, to an exterior structure of the FD drive.

[0002]

2. Description of the Related Art Generally, in an FD drive device using a 3.5-inch floppy disk as shown in FIG. 3, a resin frame is formed on a front portion of a device frame A having a U-shaped cross section opened upward. A bezel B is attached, and all the components such as the FD holder C and the upper and lower cam plates D are assembled inside the apparatus frame A, thereby completing the apparatus frame A.

By the way, in such an FD drive device, a shield cover in which the upper surface of the device frame A is fixed with a plurality of mounting screws E in order to protect the components incorporated in the device frame A from an external magnetic field or the like. F, and a pair of mounting angles H ₁ , H ₂ are fixed to the lower part of both side walls a of the apparatus frame A using a plurality of rivets G for mounting on an electronic device such as a computer. The exterior is completed.

[0004]

However, in the exterior structure of the FD drive device as described above, exterior is performed by using a plurality of mounting screws E and rivets G, a shield cover F, and a pair of mounting angles H ₁ and H _2. Therefore, the number of components required for the exterior is very large, and the process of attaching these components to the device frame A becomes complicated, resulting in a problem that the manufacturing cost becomes high.

SUMMARY OF THE INVENTION An object of the present invention is to provide an FD drive device which can be packaged with a small number of components and has a simple assembling process, in view of the above-described problem of the exterior structure of the conventional FD drive device.

[0006]

In order to achieve this object, the present invention provides an FD drive device in which components such as a bezel and an FD holder are mounted on a device frame having a U-shaped cross section opened upward. The device frame is covered with a top cover having a gate-shaped cross section having a top wall having an area corresponding to the upper surface of the device frame, and both leg sides of the upper surface cover having a mounting portion for an electronic device at a lower end thereof are fixed with fixing screws. An FD drive device fixed to both side walls of a frame is proposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of an embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral "1" denotes an apparatus frame having a U-shaped cross section opened upward. A bezel 2 formed of resin is attached to a front portion of the apparatus frame 1; Inside the bezel 2
Components such as an upper and lower cam plate 3 (shown in FIG. 2) linked to the eject button 2a, and an FD holder 4 into which a floppy disk (not shown) inserted from the slot 2b of the bezel 2 are mounted.

Then, for the exterior of the FD drive device,
In the illustrated embodiment, a top cover 5 having a gate-shaped cross section that is bent from a thin metal plate is prepared. That is, the top cover 5 has a ceiling wall portion 5a of the area corresponding to the upper surface of the apparatus frame 1, the two leg sides 5b, the distance L ₁ between the inner surfaces between 5c is of the apparatus frame 1 both side walls 1a, It is corresponding to the width L ₂ between 1b. The height L ₃ of the two leg sides 5b and 5c at which the mounting portion 5d is bent at the lower end corresponds to the height L ₄ of the FD drive device, that is, the height of the bezel 2, and the mounting portion 5d Has a screw hole 6 for attachment to an electronic device such as a computer.

A pair of through holes 7 are formed in the surface of both leg sides 5b, 5c of the top cover 5, respectively, and a plurality of through holes 7 are formed on the surfaces of the side walls 1a, 1b of the apparatus frame 1 corresponding to these through holes 7. Since the screw holes 8 are formed, both leg sides 5b, 5c can be firmly fixed to the side walls 1a, 1b of the apparatus frame 1 by the fixing screws 9 inserted from the respective through holes 7.

Since the illustrated embodiment has the above-described structure, the exterior process can be completed only by fixing the upper cover 5 to the completed FD drive device. That is, if the upper cover 5 is fitted so that the upper cover 5 is located behind the apparatus frame 1 and the top wall 5a of the upper cover 5 covers the upper surface of the apparatus frame 1, the side walls 1a, 1b
The through-hole 7 of the top cover 5 coincides with the screw hole 8 of FIG. Therefore, when the screw portion of the fixing screw 9 is inserted into these through holes 7 and the fixing screw 9 is tightened in each screw hole 8, as shown in FIG. 2, the top cover 5 is firmly fixed to the FD drive device. Is done.

In this assembled state, not only the components inside the apparatus frame 1 are protected by the top wall portion 5a of the top cover 5, but also the mounting portions 5d at the lower ends of the leg sides 5b, 5c.
By using the screw holes 6 formed in (1), a state where the FD drive device can be assembled to an electronic device such as a computer is obtained.

[0012]

As is apparent from the above description, according to the present invention, the top cover fixed to the side wall of the apparatus frame by using the fixing screw can replace the conventional shield cover and the mounting angle. Since the mounting angle and the rivet for fixing the mounting angle to the apparatus frame can be eliminated, and the exterior process can be simplified, the production cost can be significantly reduced.
