Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a magnetic disk storage body in which a window of the container into which a magnetic head is inserted during recording and reproduction can be hidden or exposed as desired.

The magnetic disk body is held in a container and rotated while being held by a disk drive, and a magnetic head is inserted through a window provided in the container and slides into contact with the magnetic disk body for recording and playback. ing.

By the way, when storing a magnetic disk, a part of the surface of the magnetic disk body is exposed through the window, that is, the window is visible, so that the magnetic disk body does not come into contact with fingers or touch other parts. Because there is a risk of contamination or damage due to contact with other objects, they are usually stored in a special bag (envelope), but in practice, it is a hassle to finally charge the bag into the bag. It is. Therefore, the current situation is that magnetic disks are stored with their windows exposed, which has the disadvantage of contaminating or damaging the surface of the magnetic disk body.

In order to improve this drawback, as shown in FIG. 4, a cover plate is installed so as to hide or expose the window 3 for inserting the magnetic head, which is provided in the container 1 housing the magnetic disk body 2. A magnetic disk storage body has been proposed which has a structure in which a magnetic disc 5 is rotatably attached to a container 1 and a window 3 of the container 1 can be hidden or exposed as desired.

This magnetic disk storage body has a cover plate 5 of the window portion 3.
The magnetic disk device 14 is pushed upward by a spring member 11 via a gear mechanism 13 attached to the rotating shaft 12 of the cover plate 5 so as to always urge the window portion 3 to the hidden position. By inserting the pin 15 attached above, the lever 16 connected to the gear mechanism 13 is pushed up, and as a result, the gear 13 attached to the rotating shaft of the cover plate 5 rotates. The cover plate 5 is pushed down, and the cover plate 5 is rotated to a position where the window portion 3 is exposed.

However, with this magnetic disk storage body,
A window 3 for inserting a magnetic head is provided on one side of the container 1, and a window 4 for inserting a pad is provided at a position corresponding to the window 3 on the other side.
When forming the covering plates 5 and 6 that hide both the window parts 3 and 4, the covering plates 5 and 6 are connected to the upper and lower ends of the rotating shaft 12, so the covering plates 5 and 6 are connected to the upper and lower ends of the rotating shaft 12. If the plates 5 and 6 are positioned vertically, it is easy to raise them, and as a result, even if one window section 3 is hidden, a portion of the other window section 4 is easily exposed.
Not only is it difficult to sufficiently hide the window, but since the cover plates 5 and 6 are connected at the upper and lower ends of the rotating shaft 12, their mechanical strength is weak, and the cover plates 5 and 6 are weak due to repeated use. However, there is a problem that the connecting portion is easily damaged.

This idea was made in view of the above circumstances, and includes a window 3 for inserting the magnetic head and a window 4 for inserting the pad.
The covering plates 5 and 6 are connected by a connecting part 8 that spans the periphery 7 of the container 1, and the covering plates 5 and 6 are slidably mounted on the container 1. 6 on the container 1 to hide or expose the magnetic head insertion window 3 and the pad insertion window 4,
With a simple structure, displacement of the upper and lower covering plates 5, 6 can be suppressed, and the mechanical strength of the connecting portion can be improved.

Hereinafter, embodiments of this invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a container made of a plastic sheet such as a PVC sheet that houses a magnetic disk body 2, and a window 3 into which the magnetic head is inserted is formed on one side of the container. A window portion 4 for inserting a pad is provided at a position facing the portion 3. 5, 5 are endless plastic sheets, or the window portions 3, 4 made of paper or the like.
These covering plates 5 and 6 are connected at a connecting part 8 that straddles the periphery 7 of the container 1, and are attached to the outer surface of the container 1 in the left and right direction. It is attached so that it can slide freely.

Further, a recess 9 is formed in the bottom peripheral portion 17 of the container 1.
On the other hand, a locking protrusion 10 is formed at a position corresponding to the bottom peripheral edge 17 of the container 1 of the connecting portion 8, and a first
As shown in the figure, when the covering plates 5, 6 are in the concealed position in the window parts 3, 4, the recess 9 on the left side of the container 1
and the locking protrusion 10 of the connecting portion 8 are engaged with each other to securely hold the covering plates 5 and 6 in the concealed position.
As shown in the figure, when the covering plates 5 and 6 are displaced to the right and are in the position where the windows 3 and 4 are exposed, the recess 9 on the right side of the container 1 and the locking protrusion 10 of the connecting part 8 are connected. The cover plates 5 and 6 are configured to be engaged with each other to ensure that the cover plates 5 and 6 are held in the exposed position.

In this case, the locking protrusion and the locking recess are not limited to the above-mentioned embodiments, and can have any suitable shape, and contrary to the above-mentioned embodiments, the locking protrusion 10 may be engaged with the container side. It goes without saying that the mating recess 9 may be formed in the connecting portion 8.

In the above configuration, when storing the magnetic disk main body 2, as shown in FIG.
6 is located in the center of the container 1, the windows 3 and 4
can be hidden. In addition, the belt-shaped covering plates 5 and 6 are moved from the above-mentioned position to the position shown by the solid line in FIG.
If it is slid to one of the positions indicated by the imaginary line,
Since the windows 3 and 4 are exposed, the magnetic disk 2 can be used for recording and reproduction.

As described above, the magnetic disk storage body according to this invention further includes a covering plate 5 for concealing the magnetic head insertion window 3 and the pad insertion window 4, respectively.
6 are connected by a connecting part 8 that straddles the periphery 7 of the container 1, the covering plates 5 and 6 are slidably mounted on the container 1, and the covering plates 5 and 6 are slidably moved on the container 1. Since the window 3 for inserting the magnetic head and the window 4 for inserting the pad are hidden or exposed by being displaced, the positional shift of the upper and lower cover plates 5 and 6 can be suppressed with a simple structure, and the connection part can be prevented from shifting. Mechanical strength can be improved.
