Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium itself such as an optical disk, a magneto-optical disk or the like, a case for accommodating a disk cartridge, a tape cassette or the like accommodating these recording media.

[0002]

2. Description of the Related Art For example, a conventional case for accommodating a magnetic tape cassette consists of a pair of case pieces rotatably connected at one end, and a pocket into which the magnetic tape cassette is fitted and held. The part is formed at one end of one case piece.

To take out the magnetic tape cassette from such a case, the case is opened, both sides of the magnetic tape cassette exposed from the pocket are gripped, and the magnetic tape cassette is pulled out from the pocket.

[0004]

By the way, in the conventional case as described above, in order to store a relatively large optical disk having a diameter of 12 cm or 30 cm and a disk cartridge in which these optical disks are stored, In order to prevent wobbling of the recording medium when the case is opened and closed, and to prevent damage to the pocket by taking the recording medium straight out of the pocket, it is necessary to provide a side wall on the side of the case piece.

However, when the side wall is provided on the case piece, the side wall becomes an obstacle when the recording medium is taken out from the case, and it becomes impossible to grip both side portions of the recording medium, which makes it difficult to take out the recording medium.

In view of the above circumstances, the present invention is to provide a case suitable for accommodating a recording medium, particularly a disc cartridge accommodating an optical disc, a magneto-optical disc, or the like.

[0007]

The case for storing a recording medium according to the present invention is mutually supported by the rotation fulcrums 6 and 7 so as to be rotatable around the rotation fulcrums 6 and 7 near one end of each case. And the first and second case pieces 2 and 3, which are
The case piece 2 has a projection 13 provided on the one end side of the rotation fulcrum 6 and elastic holding portions 71 and 72 for elastically holding the recording medium 80, and the projection 13 moves as the projection 13 moves. A slider 7 provided in the second case piece 3 so as to be movable along the second case piece 3.
0, respectively, and the first case piece 2 is rotated so as to be separated from the second case piece 3 and the projection 13 is rotated.
By orbiting the rotary support points 6 and 7 to move the protrusion 13 to the other end side of the second case piece 3, and the movement of the protrusion 13 causes the slider 70 to move to the second side. The recording medium 80 held by the elastic holding portions 71 and 72 is projected from the second case piece 3 by moving the recording medium 80 along the case piece 3 to the other end side.

[0008]

In the recording medium housing case according to the present invention, the recording medium 80 housed in the case 1 automatically protrudes to the outside of the case 1 when the case 1 is opened. In addition, at this time, as the protrusion 13 moves to the other end side of the second case piece 3, the slider 70 also moves to the other end side along the second case piece 3, so that the protrusion 13 moves to the slider 70. The direction in which the force is applied and the direction in which the slider 70 moves coincide with each other. Further, since the slider 70 elastically holds the recording medium 80, even if the recording medium 80 protrudes to the outside of the case 1 due to the opening operation of the case 1, the recording medium 80 drops from the inside of the case 1. Hard to do.

A recess 28 is provided on the bottom surface 22 of the case piece 3, and the slider 70 slides in a state in which both surfaces are restricted by the recess 28 and the upper plate 43 of the lid member 42.

Next, the movement of the disc cartridge housing case 1 will be described.

Case 1 which is closed as shown in FIG.
To open, the opening / closing handle 30 is first rotated in the direction of arrow a to bring it to the state shown in FIG. 6 (B). At this time, the engagement between the concave portion 33 of the opening / closing handle 30 and the protrusion 21 of the case piece 3 is released, and the case piece 2 and the case piece 3 are unlocked. Then, lift the opening / closing handle 30 as it is, and
The case piece 2 is rotated as shown in FIG.

With the rotation of the case piece 2, FIG.
As shown in (C), the protrusion 13 of the case piece 2 is replaced by the case piece 3.
The slider 70 slides in the groove 73 of the slider 70 via the guide groove 27. As a result, the slider 70 moves from the position shown in FIG. 2 to the position shown in FIG.
0 is also slid on the case piece 3 by the slider 70, and is pushed out of the case 1 as indicated by the alternate long and short dash line in FIG.

To close the case 1, the opening / closing handle 30 is grasped and the case piece 2 is rotated to approach the case piece 3. With the rotation of the case piece 2, the protrusion 13 moves in the opposite direction to the above-described movement when the case 1 is opened to move the slider 70 back to move the disk cartridge 80 to the case 1.

In the above embodiment, the projection 13
Although the slider 70 is slid once by the above, and the cartridge 80 is pushed out of the case piece 1 by this sliding, the protrusion 13 is brought into direct contact with the side portion of the cartridge 80 and the slider 70 is not used. Alternatively, the cartridge 80 may be directly pushed out of the case 1.

The present invention can be widely applied not only to the case 1 for storing a disk cartridge, but also to a case for storing an optical disk, a magneto-optical disk, a magnetic tape cassette or the like.

[0034]

In the recording medium storage case according to the present invention, the recording medium stored in the case automatically protrudes to the outside of the case when the case is opened.
By sandwiching the portion of the recording medium protruding from the case, the recording medium can be easily taken out from the case. Moreover, at this time, since the direction in which the force is applied from the protrusion to the slider and the direction in which the slider moves are coincident with each other, the opening operation of the case can be smoothly performed with a small force. Further, even if the recording medium is projected to the outside of the case due to the opening operation of the case, the recording medium does not easily drop from the inside of the case, so that the safety of the recording medium is high.

Further, even if side walls of the case piece are provided with side walls for preventing the wobbling of the recording medium and allowing the recording medium to be taken out straight from the case, a part of the side portion of the recording medium is Since it is pushed out of the case, the recording medium can be easily taken out of the case by grasping the side portion thereof.
