Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the improvement of the front panel of a floppy disk storage device, particularly the floppy disk loading/unloading section.

[Conventional technology]

FIG. 6 is a perspective view showing a conventional floppy disk storage device. In the figure, 1 is a main body that houses a floppy disk (not shown), 2 is a front panel provided on the front of this main body that prevents radio wave leakage, and 3 is a panel opening made in this front panel. The floppy disk is inserted into the panel opening 3 to accommodate the floppy disk in the main body 1, and the floppy disk pushed out by an injector (not shown) in the main body 1 is inserted into the panel opening 3. It is designed to be extracted from the

[Problem that the invention attempts to solve]

The conventional floppy disk storage device is constructed as described above, but although the front panel 2 is equipped with measures against radio wave leakage, the panel opening 3 remains open. There was a problem in that it was impossible to prevent radio wave leakage. Furthermore, since the opening remains open, there is a risk that dust and the like may enter the main body 1 through the opening 3.

This idea was made to solve the problems mentioned above, and aims to provide a floppy disk storage device that reliably prevents radio wave leakage and does not allow dust to enter. .

[Means for solving the problem]

The floppy disk storage device according to this invention has a first door that opens inward and is designed to prevent radio wave leakage in the panel opening of the front panel, and a door opening is bored in this first door. The door opening is equipped with a second door that opens to the outside and is designed to prevent radio wave leakage.

[Effect]

With this invented floppy disk storage device,
At all times, the opening is securely closed by two doors designed to prevent radio wave leakage, and when a floppy disk is inserted, the first door opens inward to allow the floppy disk to be inserted, and the floppy disk is closed. When removing the floppy disk, the second door opens outward to allow the floppy disk to be removed.

[Example of idea]

Fig. 1 is a perspective view showing an embodiment of this invention, Fig. 2 is a sectional view taken along the line - Fig. 1, and Fig. 3 is a sectional view taken along the line - Fig. 1. are the main body, front panel, and panel opening similar to those of the conventional device described above. Reference numeral 4 denotes a door body that closes the panel opening 3 and is designed to prevent radio wave leakage, and is composed of two doors as described later. Reference numeral 4a denotes a first door which is installed to prevent radio wave leakage and is located inside the panel opening 3, and whose upper side is rotatably supported on the front panel 2 by a shaft 4b. A certain lower side is brought into contact with the opening edge of the panel opening 3, and rotation to the outside is restricted. 4c is wound around the shaft 4b, and the first
A torsion coil spring that always biases the door 4a in the closing direction, 4d is a door opening formed in the first door, and 4e is a radio wave leak that is located outside of this door opening and blocks it. The second door is equipped with a countermeasure, and its upper side is rotatably supported on the first door 4a by a shaft 4f, and its lower side, which is a free end, is in contact with the opening edge of the door opening 4d, and the inside Rotation to is regulated. 4g is an elastic protrusion for maintaining the closed state of the second door 4e.

The first door 4a is always biased counterclockwise (Fig. 3) by a spring 4c, and its lower side faces the panel opening 3.
In other words, the panel opening 3
is kept closed. Further, the second door 4e holds the door opening 4d in a closed state by the elastic protrusion 4g.

FIGS. 4 and 5 are diagrams showing the operating state of the floppy disk storage device according to this invention. First, referring to FIG. 4, the case where a floppy disk is inserted into the main body will be explained. In FIG. 4, when the door body 4 is pushed by the tip of the floppy disk 5,
Since the second door 4e contacts the opening edge of the door opening 4d and opens only to the outside, the entire door 4 opens inward, and the floppy disk 5 is inserted into the main body 1 through the panel opening 3. Ru. When the floppy disk 5 is completely stored in the main body 1, the spring 4
c, the door body 4 returns to its original position and closes the panel opening 3.

Next, the case of taking out the floppy disk will be explained with reference to FIG. When the floppy disk 5 is pushed back from inside the main body 1 by an injector mechanism (not shown) inside the main body 1, its tip pushes the door body 4 from inside. At this time, the first door 4a contacts the opening edge of the panel opening 3 and does not open outward.
The second door 4e is pushed open to the outside, and the tip of the floppy disk 5 is exposed to the outside. As a result, the floppy disk 5 is pulled out through the panel opening 3. After being pulled out, the second door 4e rotates clockwise under its own weight, and then when pressed lightly with a finger, the elastic protrusion 4g closes the door opening 4d.

In the above embodiment, the second door 4e is returned to its original position by its own weight and kept closed by the elastic protrusion 4g. However, if a torsion coil spring is used like the first door 4a, Elastic protrusion 4g
can be omitted.

[Effect of idea]

As explained above, this idea is to provide a door body that prevents radio wave leakage at the panel opening of the front panel, and because this door body always closes the panel opening, radio wave leakage from the panel opening is prevented. Also, the intrusion of dust and the like can be reliably prevented.
