Abstract

PURPOSE:To prevent dust from entering after insertion of a floppy disk medium and to prevent the trouble due to the entry of dust. CONSTITUTION:An inserting port is closed by a shutter 3 before the insertion of the floppy disk medium 7. The inserting port is closed by a shutter 5 after the insertion of the floppy disk medium 7. Consequently, both after and before the insertion of the floppy disk medium, an opening at the device is eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floppy disk drive device, and more particularly to a dust intrusion prevention mechanism in a 3.5 inch floppy disk drive device.

[0002]

2. Description of the Related Art Conventionally, in a floppy disk drive device, a door is provided at the insertion port of a floppy disk medium in order to prevent foreign matter from entering the device. This door closes the insertion slot only when the floppy disk medium is not inserted. When the floppy disk medium is inserted, the door is pushed into the device by the floppy disk medium, so that the trailing edge of the floppy disk medium is exposed to the outside of the device and a gap is created between the floppy disk medium and the device. Will end up.

In such a conventional floppy disk drive, a gap is created between the floppy disk drive and the apparatus due to the insertion of the floppy disk medium, so that there is a problem that dust easily enters through the gap.

Further, if dust that has entered the inside of the apparatus together with air through the gap adheres to the magnetic material coated surface of the floppy disk medium or the sliding surface of the magnetic head, it may damage the floppy disk medium or the magnetic head. There is a problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned problems of the prior art, and can prevent the intrusion of dust after inserting a floppy disk medium and prevent obstacles caused by the intrusion of dust. It is an object of the present invention to provide a floppy disk drive device that can be used.

[0006]

According to the present invention, there is provided a floppy disk drive device which closes an insertion port of the floppy disk medium before inserting the floppy disk medium and opens the insertion port in association with an inserting operation of the floppy disk medium. And a second shutter member that closes the insertion port after inserting the floppy disk medium and opens the insertion port in conjunction with the ejecting operation of the floppy disk medium. To do.

[0007]

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, a frame 1 for fixing a floppy disk medium (not shown) to a drive unit (not shown) and ejecting the floppy disk medium is provided in a floppy disk drive according to an embodiment of the present invention. There is.

A bezel 2 is mounted on the front surface of the floppy disk drive, and a shutter 3 is mounted on the bezel 2 so as to be openable and closable toward the inside of the apparatus. Since the upper end of the shutter 3 is rotatably supported by the bezel 2 about the upper end, the shutter 3 rotates so that the lower end moves upward in response to the insertion of the floppy disk medium.

The frame 1 is interlocked with the movement operation of the eject button 4, and when the eject button 4 is pushed in, it operates so as to eject the floppy disk medium fixed to the drive portion.

A shutter 5 is mounted on the frame 1, and the shutter 5 is attached to a bezel 2 by a spring 6.
Is pressed inside. Since the shutter 5 has a shape that can be stored in the space inside the device, the addition of the shutter 5 does not affect the outer shape of the device or the main internal mechanism.

Before the floppy disk medium is inserted, the frame 1 is retracted inside the apparatus, so the shutter 5 is also retained by the frame 1 at the position where the shutter 5 is retracted inside the apparatus to open the insertion port.

At this time, since the shutter 3 operates so as to close the insertion opening and is pressed against the shutter 5, the contact surface with the shutter 5 is formed so that no gap is formed in the insertion opening. Therefore, when the insertion port is closed by the shutter 3, it is possible to prevent dust from entering the device.

FIG. 2 is a perspective view of the frame 1 of FIG.
In the figure, the frame 1 is configured such that the left and right side surfaces project forward, and the projecting portions are provided with elongated holes into which the shafts of the shutter 5 are inserted and bosses for mounting the springs 6, respectively. .. The eject button 4 is fixed to the frame 1.

When the shaft of the shutter 5 is inserted into and supported by the elongated hole of the frame 1, and the spring 6 is attached to the boss of the frame 1, the shaft of the shutter 5 is pressed against one end of the elongated hole of the frame 1 by the spring 6. Be done.

FIGS. 3 and 4 are diagrams showing the inserting operation of the floppy disk medium in the embodiment of the present invention. The operation when the floppy disk medium is inserted into the floppy disk drive device of the embodiment of the present invention will be described with reference to FIGS.

When the floppy disk medium 7 is inserted into the insertion slot, the lower end of the shutter 3 is flipped upward to open the insertion slot. At this time, the shutter 5 is movable toward the inside of the apparatus along the elongated hole of the frame 1 so that the operator's finger can sufficiently push the floppy disk medium 7 into the apparatus (see FIG. 3).

When the floppy disk medium 7 is sufficiently pushed into the apparatus, the entire frame 1 moves in the direction of the insertion port, the eject button 4 is pushed out of the apparatus, and the shutter 5 also moves along the inside of the bezel 2. One end moves upward.

That is, as the frame 1 moves, one end of the shutter 5 moves while being pressed against the inside of the bezel 2 by the spring 6, so that one end of the shutter 5 stands up along the inside of the bezel 2. One end of the shutter 5 finally stops at the position where it comes into contact with the shutter 3,
The insertion port is closed (see Fig. 4).

When the eject button 4 is pushed in to eject the floppy disk medium 7, the shutter 5 is also pulled inside the apparatus as the frame 1 moves toward the inside of the apparatus. That is, the shutter 5 is pulled inside the device along the inside of the bezel 2 to open the insertion port.

At this time, the ejecting operation of the floppy disk medium 7 is not started until the frame 1 is completely moved toward the inside of the apparatus, so that the shutter 5 and the floppy disk medium 7 do not interfere with each other.

As described above, the insertion opening is closed by the shutter 3 before the insertion of the floppy disk medium 7, and the insertion opening is closed by the shutter 5 after the insertion of the floppy disk medium 7, whereby the floppy disk medium 7 is inserted. Even after that, there is no gap with the device. Therefore, it is possible to prevent the intrusion of dust after the floppy disk medium 7 is inserted, and it is possible to prevent the obstacle due to the intrusion of dust.

[0023]

As described above, according to the present invention, the insertion opening is closed by the first shutter member before the floppy disk medium is inserted, and the insertion opening is closed by the second shutter member after the floppy disk medium is inserted. By closing, it is possible to prevent the intrusion of dust after the floppy disk medium is inserted, and it is possible to prevent an obstacle due to the intrusion of dust.
