Abstract

PURPOSE:To shift a disk onto a turntable without giving any damage to the disk at the time of reproduction of the disk, by flexing holding members installed above and below the disk. CONSTITUTION:When a disk-storing case is inserted into a prescribed position in a reproducing device, a lock releasing mechanism is engaged with the pit 34 of a holder 20 and a locking arm member is flexed in the direction shown by an arrow A and a latch 38 is removed from the recessed part 58 of an enclosure, and then, the enclosure 50 is released. At the same time, a grasping mechanism 60 operates and grasps edge parts 44 and 45 of holding members 40 and 41. When the enclosure 50 is taken out from the device, the grasping mechanism 60 moves and the holding members 40 and 41 are gradually flexed, and then, a disk 10 is moved toward the underneath of the holder 20 and finally moved to a rotating mechanism 70 installed in a reproducing device. After the termination of the reproduction, the grasping mechanism 60 is again moved in the opposite direction and the disk 10 is returned into the holder 20, and then, the holder is contained after the enclosure 50 is again inserted into the device.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical disk device, and more particularly to a case for housing a disk for recording and reproducing high-density information.

In general, discs for recording and reproducing high-density information are
The structure is designed to prevent dust, fingerprints, etc. from adhering to the recording surface. As one example, the disc is stored in a disc company case and inserted into a playback device together with the case during playback. When the case is inserted, a disc ejector provided in the playback device grasps the outer edge of the disc, pulls out the disc (from the case), and transfers the disc to the turntable for playback. To remove the disc from the player, the above procedure is reversed, and an empty case is inserted into the player to accommodate the disc.

With the above method, there is no need to touch the disc directly.
Moreover, the disk storage case can also be configured simply. However, this method has drawbacks such as damaging the outer periphery of the disk when mechanically loading and unloading the disk, and requiring a complicated mechanism for the disk ejecting device.

The present invention enables the disc to be transferred onto a turntable without mechanically gripping the outer periphery of the disc by bending the clamping members disposed above and below the disc surface during disc playback. The present invention provides a disc storage case.

According to the present invention, the object is to provide a disk holder comprising a holding member having a substantially circular opening for storing a disk in a disk storage case, and a pair of flexible clamping members for holding the upper and lower sides of the disk surface; A disc storage case is obtained by comprising an envelope having an edge opening for storing the discs in a manner that allows the discs to be taken in and taken out.

Next, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, this embodiment has a general structure including a holder 20 for storing the disk IO and an envelope 50 having an opening on the front side in the insertion direction of the holder 20. The envelope 50 is formed by ultrasonically bonding three sides of an upper lid part and a lower lid part made of, for example, FRP, and has a flat storage space 52 inside thereof, which is slightly larger than the cage 20. The storage space 52 is closed on three sides, and an opening 54 for taking in and out the holder 20 is provided on one side. Referring to FIG. 2, the cage 20 of this embodiment has a holding portion #30 formed over the entire width of the flat portion 31. One plane part 31 is a pair of convex parts 3
2.33 and an edge 35 are formed on the front and back surfaces of the end, and a pair of locking arms 36 are formed on both sides, and a substantially circular opening 39 for accommodating the disk 10 is formed in the center of the hollow. It is equipped with The flat portion 31 opens the disk 10 into a circular opening 39.
It has a thickness that allows it to be smoothly accommodated. The locking arm $t36 has a narrow base 37 and is formed so as to be able to bend in the direction of the arrow, and has a tip 38 with an inclined surface and a hook. 1+convex portion 32.
33, a bit 34 is formed respectively. Further, the retainer 20 is provided with a pair of clamping members 40 and 41 on the front and back surfaces near both ends to clamp the flat part 31 of the holding member 30.

The clamping members 40, 41 usually restrict the axial movement of the disk 10 and prevent the housed disk 10 from wobbling. The holding member 40, 41 has one end rotatably attached to the holding member 3.
0, and the holding member 300 is integrally molded at the other end of the holding member 300.
Edges 44 and 45 similar to edge 35 are formed. Referring again to FIG. 1, mounting of the envelope 50 and the retainer 20 will be described. When the retainer 20 containing the disk 10 is inserted into the envelope space 52 through the envelope opening 54, the locking arm member 36 fits into the envelope 500 and the opening 57,
In addition, the latch 38 fits into the recess 58 inside the side wall to stably and firmly hold the retainer 20 in the envelope 50. At this time, the protrusions 32,33 are inserted into the notches 46,47 formed at corresponding positions, and the protrusions 32,33 of the holding member are inserted into the notches 46,47 formed at corresponding positions.
and the edge 35, the edge 44,45 of the clamping member, and the envelope 50.
The outer surface of the front and back surfaces are substantially the same plane.

Next, with reference to Figs. 3 and 4, a case will be described in which a disc is played back using the storage case of the present invention. Third
This figure and FIG. 4 are cross-sectional views of FIG. 1 taken in the xx' direction, with a portion of the reproducing device added thereto.

When the storage case of this embodiment is inserted into a predetermined position in the playback device, a lock release **<not shown) is provided on the retainer 20 and engages with the nine bits 34 to grip the retainer 20. It works as expected. Furthermore, the lock release mechanism bends the lock arm member in the direction of arrow entry (FIG. 2) to move the latch 38 into the envelope recess 58.
to release the envelope 50. At the same time, the gripping mechanism 60
It moves with force and grasps the edges 44° and 45 of the clamping members 40 and 41 arranged on the back side. At this time, the disc contacts the clamping members 40 and 41 of the 10th disc and is prevented from falling. When the envelope 50 is taken out of the apparatus, the gripping mechanism 60 moves in the direction of arrow B (FIG. 4). The clamping members 40 and 41 gradually bend as the gripping mechanism moves, and hold the disk 10 in the retainer 20.
and is transferred to a rotation mechanism 70 for rotating the disc disposed within the playback device. The rotation mechanism 70 has a turntable 75 and a center shaft 72 that engages and aligns the center hole 15 of the disk 10, and is driven by a motor 76. When the playback is finished, the gripping mechanism 60 is moved in the opposite direction again to return the disk IO into the holder 20. The envelope 50 is inserted into the device again, the holder 20 is housed, and the regeneration operation is completed. Naturally, in the case of backside playback, the storage case must be turned over and inserted into the device.

As explained above, the present invention solves the disadvantage of gripping the disk body and damaging the disk by disposing bendable holding members on the front and back sides of the round retainer for storing the disk, and The disk loading mechanism also has a simple configuration, which has the effect of reducing costs.
