Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a storage case for a disk such as a video floppy disk.

[Background of the invention]

A cassette-type magnetic disk in which a flexible magnetic disk is housed in a hard case is widely known.

A shutter member is attached to the magnetic disk storage case so as to be openable and closable in order to protect the magnetic disk. In other words, when this shutter member is opened, the magnetic disk is exposed through the elongated head insertion opening provided in the main body of the storage case, allowing recording and reproducing operations, and the head opening is covered. When the shutter member is closed in this manner, dust and dust are prevented from entering the storage case main body through the head opening, and the magnetic disks within the storage case main body are protected.

By the way, the main body of the storage case up to now is, for example, the 10th
11 and 12, and the shutter member is constructed as shown in FIG. A claw 55a has protrusions 52a and 52b formed at the end of the storage case main body 53 on the guide groove 54 side.

55b, and the shutter member 51 is arranged perpendicularly to the kite direction of the guide groove 54 (the shutter member 51 shown in FIG. The guide protrusion 52a is inserted into the guide groove 54 by pushing in) and bending the claws 55a and 55b.

52b. In addition, 56 is a write protector, 57 and 58 are a pair of positioning holes configured for positioning the magnetic disk when it is installed in a disk recording/reproducing device, 59 is an elongated opening for inserting the head, and 60 is a circular opening in the center.

However, the storage case made in this way has only 5 claws.
The guide groove 54 appears to be interrupted at the portions 5a and 55b, and therefore the shutter member 51
The guide protrusions 52a and 52b are discontinued at this discontinuous portion 61.
a, 62a, 61b.

62b, the shutter member 51 does not slide smoothly.

Also, depending on the condition of the claws 55a and 55b, the shutter member 51
There is also an accident in which the storage case falls off from the storage case main body part 53.

Also, when attaching the shutter member 51 to the storage case main body 53, the guide protrusion 52 of the shutter member 51
a and 52b must be placed exactly opposite the claws 55a and 55b formed at the end of the storage case body 53 on the guide groove 54 side, which reduces assembly efficiency.

Furthermore, discontinuous portions 6 for forming the claws 55a and 55b are provided.
1a, 62a, 61b, and 62b must be formed, so when the storage case main body 53 is constructed by molding means, the mold has a complicated structure, which increases the cost accordingly.

7 to 9 are a bottom view, a front view, and a side view of a portion of the shutter member disposed in the main body of the disc storage case.

In each figure, 1 is an upper case that constitutes the disk storage case body A, and 2 is a lower case that cooperates with the upper case 1 to constitute the disk storage case body A.

This lower case 2 is formed into a generally shallow dish shape with a joint wall of a constant height extending around the entire circumference along the outer periphery, and this joint wall is butted against the lid-shaped upper case l. Upper case 1 and lower case 2 are integrated by means such as ultrasonic welding.

The upper case 1 and the lower case 2 are made of resin, such as ABS resin containing an antistatic agent.

Further, a liner (not shown) made of a non-woven fabric such as rayon is provided on the inner surface of the lower case 2 by heat welding or ultrasonic welding to prevent dropout and abrasion of the magnetic disk 3 and generation of static electricity. There is.

A magnetic disk 3 is housed in a case formed by combining an upper case 1 and a lower case 2. The magnetic disk 3 is a flexible magnetic disk that is based on a disc-shaped polymer film and has a magnetic layer uniformly formed on its lower surface.

A circular opening is formed in the center of the magnetic disk 3, and a ring-shaped center plate 4 is fixed to this opening. A motor shaft insertion hole is formed in the center of the center plate 4.

A circular opening 5 is formed in the center of the lower case 2, and the center plate 4 is placed in this opening 5 with some play.

An elongated hole (not shown) is formed in the upper case 1, and an elongated hole 6 for head insertion is formed in the lower case 2, and the magnetic disk 3 is exposed from these elongated holes 6.

A recess 7 is formed on the outer surfaces of the lower case 2 and the upper case 1 including the portion where the elongated hole 6 is formed, and a shutter member 8 made of metal or synthetic resin and having a substantially U-shaped cross section is provided in the recess 7. It is slidably attached and slides while being guided by a predetermined guide means. By the action of this guide means, the magnetic disk 3 is exposed to the outside through the elongated hole 6 during recording/reproduction use, and the elongated hole 6 is closed by the shutter member 8 to protect the magnetic disk 3. The shutter member 8 slides so that the magnetic disk 3 is not exposed to prevent dust from entering.

Further, the lower case 2 is provided with a pair of positioning holes 9 and 10 for positioning the magnetic disk when it is installed in a disk recording/reproducing device. In addition, one positioning hole 9
The hole is a long hole, so that even if there is some error in the position of the hole, it can be tolerated.

Furthermore, in a predetermined position of the disc storage case body A,
A write protector 11 is configured to enable or prohibit writing to the magnetic disk 3 inside the storage case main body A. That is, write protector 1
When the write protector 11 is not removed from the predetermined position, it is in a writable state, and when the write protector 11 is removed from the predetermined position, it is in a write-inhibited state.

The shutter member 8 is constructed as shown in FIGS. 4 to 6, and its basic structure is the same as that of the conventional shutter member 8, so a detailed explanation thereof will be omitted.

Note that 8a and 8b are guide protrusions of the shutter member 8 formed by punching and bending, 8c and 8d are guide protrusions of the shutter member 8 formed by pressing, and 8e is a guide protrusion on the disk storage case main body A side. Locking pawl (not shown)
is the locked portion, and when the shutter member 8 is located at the position of the elongated hole 6, it is locked, and the elongated hole 6 is maintained in a closed state by the shutter member 8.

12 is a shutter member 8 formed at the end portion of the recess 7
This is a guide groove for the slide. This guide groove 12 is
Conventionally, the right end portion was closed by the rib 13, but in the present invention, at least the rib in the guide groove 12 portion is removed, that is, the insertion opening 14 is formed in the guide groove 12. It is characterized by the fact that it is formed.

In addition, the rib 13 is not formed not only in the guide groove 12 portion but also in both side portions 15a and 15b of the guide groove 12 (up to about 1/3 of the recess 7 on the example portion 15b side of the guide groove 12). It looks like this.

It goes without saying that the configuration of the rib 13 portion described above was for the lower case 2, but the rib 16 is formed in the same way on the upper case 1 side, that is, at least the portion facing the guide groove 12. No rib 16 is formed in the portion of the guide groove 12 that faces the other side portion 15a.

17 is a groove formed in the side wall portion of the lower case 2.

When attaching the shutter member 8 to the disk storage case configured as described above, please refer to FIG. 1 or 7.
If the shutter member 8 is placed on the right side of the disc storage case main body A in the state shown in the figure, and the shutter member 8 is slid from right to left, the guide protrusion 8a of the shutter member 8 will be removed.

8b and the guide protrusions 8c and 8d are guided and inserted through the insertion opening 14 of the guide groove 12, and the locking claw provided on the side of the disc storage case main body A engages with the claw-shaped locked portion 8e. Since the shutter member 8 is guided into the groove 17, the shutter member 8 can be easily attached to the disc storage case main body A.

Moreover, since the movable portion of the guide groove 12 of the shutter member 8 does not need to be provided with claws 55a and 55b as in the conventional case, the guide groove 12 does not appear to be interrupted, and therefore the shutter member 8 Malfunctions such as loss of smooth sliding do not occur.

Further, since the conventional claws 55a and 55b are not provided, there is no accident that the shutter member 8 falls off from the disk storage case main body A.

Although the ribs 13 are removed at the guide groove 12 and other parts, the ribs 13 are not completely removed, so the shutter member 8 falls off from the disk storage case main body A due to the remaining ribs 13. I don't. Furthermore, when attaching the shutter member 8 to the disk storage case main body A, if the tip side of the shutter surface of the shutter member 8 is slightly opened, the remaining rib 13 will not interfere with the attaching operation. .

Furthermore, there is no need to construct the claws 55a and 55b as in the conventional case, and the construction of the disc storage case main body 80 is simple, and when the disc storage case main body A is constructed by a molding means, the mold is The structure is simple and the cost is low.

[Effects] The disc storage case according to the present invention includes a storage case main body in which an opening is formed, a shutter member attached to the storage case main body that opens and closes the opening by sliding, and this shutter member. and a slide mounting guide mechanism that allows the shutter member to be mounted in the sliding direction of the slide guide mechanism when the shutter member is mounted on the storage case main body.
