Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a method for storing a disk within a floppy disk device main body.
The present invention relates to a disk ejector mechanism for a floppy disk device that has a dust-proof function when inserted into a floppy disk device.

(Prior Art) Conventionally, in a floppy disk device, a disk, which is a magnetic recording medium, is frequently taken in and taken out.

Therefore, dust may enter the floppy disk device body from the outside, especially when a disk is inserted. There is not much of a problem when the recording density is relatively low, but when using a disk with a high recording density, a dustproof function similar to that of a hard disk device is required.

As a means to realize such anti-AM function, for example,
As shown in the figure, a door 11 is provided on a front panel 10 of a floppy disk device.

The door 11 is attached to the front panel 10 at all ends, and is always held in place by a spring 12.
Forced to the side. When the disk 13 is inserted from the outside through the inlet/outlet slit 14 formed in the front panel 10, the door 11 is rotated away from the front panel 10 by the pressing force of the disk 13, as shown in FIG. When the disk 13 is inserted into the floppy disk device main body, it is loaded into a spindle mechanism (not shown) in the state shown in FIG. 6. When the disc 13 is ejected from inside, the door 11
The state returns to the state shown in FIG.

A mechanism using such a door 11 makes it possible to prevent dust from entering from the outside.
The dust adhering to the disc 13 enters the inside together with the disc 13. Therefore, due to dust attached to the disk 13,
A situation may occur that interferes with the read/write operations of the magnetic head.

(Problems to be Solved by the Invention) As described above, in the conventional prison prevention mechanism, dust adhering to the disk 13 enters the floppy disk device main body when the disk 13 is inserted, and has a negative effect on the magnetic head. There is a problem of giving.

An object of the present invention is to reduce the intrusion of dust from the outside when no disk is inserted into a floppy disk, and furthermore, it is possible to significantly prevent troubles to the magnetic head caused by dust attached to the disk. The object of the present invention is to provide a disk ejector mechanism for the device.

[Structure of the Invention] (Means and Effects for Solving the Problems) The present invention provides a floppy disk device with a front panel and a
It is a disk ejector mechanism with a mechanism. The front panel is provided on the side surface of the floppy disk device body, and has a slit for inserting and removing the disk.

The dustproof mechanism includes first and second dustproof mechanisms provided within the floppy disk device main body. The first dust-proofing mechanism has a dust-proofing member that contacts one side of the disk inserted into the 70 mm disk device main body through the loading/unloading slit, and rotates about one end as a fulcrum as the disk is inserted or removed. configured to drive. The second dust-proofing mechanism has a dust-proofing member that contacts the other side of the disk inserted into the floppy disk device main body through the loading/unloading slit, and rotates about one end as a fulcrum in response to loading/unloading of the disk. configured to drive.

With such ms, it is possible to remove dust adhering to the disk when the disk is inserted, and to prevent harmful effects on the magnetic head due to dirt adhering to the disk.

(Example) The present invention will be described in detail below with reference to the drawings. FIG. 1 is a side sectional view showing the structure of the disk loading/unloading mechanism 11N of the same embodiment. In FIG. 1, the front panel 20 is a floppy disk device main body (hereinafter simply referred to as the device main body).
A slit 14 for taking in and taking out the disk 13 is formed on the side surface of the disk. An anti-ml structure is installed inside the main body of the front panel 20.

The dustproof mechanism includes a first dustproof mechanism 21 and a second dustproof mechanism 22, which are provided opposite to each other. The first dustproof m structure 21 includes a mechanism main body 21a whose one end is attached to a predetermined position of the front panel 20, a dustproof member 21b attached to this mechanism main body 21a, and a gl structure main body 21a that is always directed toward the front panel 20 side. It consists of a spring 21c for urging and a limiting member 21d integrated with the mechanism main body 21a. Similarly, the second anti-mR structure 22 includes the front panel 20
a mechanism main body 22a with one end attached to a predetermined position;
It consists of a dustproof member 22b attached to the mechanism main body 22a and a spring 22c for always urging the mechanism main body 22a toward the front panel 20 side.

Each of the dustproof members 21b and 22b is a pad made of felt, for example, and is positioned so as to block the loading/unloading slit 14 from the outside when the disk 13 is not inserted. The restriction member 21d is formed at a predetermined angle with respect to the R structure body 21a, and is a member for restricting movement of the mechanism body 21a toward the front panel 20 when the disk 13 is loaded.

Next, the operation of this embodiment will be explained. First, disk 13
When not inserted, as shown in FIG. 1, each mechanism main body 21a of the first dustproof mechanism 21 and the second dustproof mechanism 22,
22a is biased toward the front panel 20 by the action of each spring 21C122c. As a result, the dustproof members 21b and 22b attached to the respective mechanism bodies 21a and 22a operate the door, thereby blocking the entry of dust from the outside.

Next, when the disk 13 is inserted through the loading/unloading slit 14, the disk 13 is inserted into each dustproof member 21b, 22b.
The mechanism main bodies 21a and 22a are pressed against each other. That is, as shown in FIG. 2, the mechanism main body 21a of the first dustproof mechanism 21 rotates about the point at which the front panel 20 is attached to the upper side inside the main body of the apparatus.

Similarly, the mechanism main body 22a of the second dustproof mechanism 22 rotates about the upper part of the inside of the device main body where the front panel 20 is attached as a fulcrum. At this time, since the disk 13 is inserted with its surface in contact with the dustproof member 21b, the dust attached to the surface is removed by the dustproof member 21b. Similarly, since the back surface of the disk 13 is brought into contact with the dustproof member 22b, dust attached to the mounting surface is removed by the dustproof member 22b.

When the disk 13 is completely inserted into the apparatus body, it will be loaded onto a spindle mechanism within the apparatus body. The disk 13 is rotationally driven by this spindle mechanism. In this loaded state, as shown in FIG. 3, the mechanism main body 22a of the second dustproof mechanism 22
b is in contact with the back surface of the disk 13 and held at a predetermined position within the main body of the apparatus.

In addition, the groove main body 21a of the first dustproof mechanism 21 can be
Rotational movement toward the front panel 20 side is restricted.

Thereby, when the disc 13 is ejected, it is possible to prevent a situation where the disc 13 is blocked by the mechanism main body 21a of the first dustproof mechanism 21 and cannot be ejected. Here, the limiting member 21d and the dustproof member 22b come into contact with the rotating disk 13, but the spring 21
The adjustment of 22c and 22c does not cause any trouble to the rotational drive of the disk 13.

When the disc 13 is ejected, each mechanism main body 21a of the first dustproof mechanism 21 and the second dustproof mechanism 22,
22a rotates toward the front panel 20 and returns to the state shown in FIG.

In this way, when the disk 13 is not inserted, the dustproof members 21b and 22b act like a door, and the number of ribs entering from the outside through the slit 14 can be significantly reduced. Further, when the disk 13 is inserted, dust adhering to both surfaces of the disk 13 is removed by the dustproof members 21b and 22b.

Therefore, it is possible to significantly prevent a situation in which dust adhering to the disk 13 adversely affects the magnetic head in contact with the surface of the disk 13.

[Effects of the Invention] As described in detail above, according to the present invention, in a floppy disk device, it is possible to significantly reduce the intrusion of eggs from the outside when no disk is inserted into the device main body. Further, by removing dust that adheres to the disk when the disk is inserted, it is possible to greatly prevent a situation where the read/write operation of the magnetic head may be hindered.

As a result, the dust-proofing effect of the floppy disk device can be improved, and even when a high-density disk is used, it is possible to prevent the occurrence of trouble in the magnetic head due to dust. This makes it possible to realize reliable read/write operations on the disk.
