However, in the above-mentioned conventional optical disk storage, no consideration has been given to the convenience in use in taking out and storing the optical disk. That is, in order to use the conventional optical disk storage body, a three-stage operation of holding the holding plate with one hand, opening and closing the lid with the other hand, and taking out and storing the optical disk with the other hand is required. It required a lot of trouble. Further, when engaging with the optical disk holding plate, the inner periphery of the center hole may be rubbed against the engaging projection and may be damaged. If the inner periphery of the center hole of this optical disk is slightly damaged, a gap is formed between the center hole and the spindle that rotates the optical disk, and the rotation of the optical disk becomes eccentric, or the optical disk rotates relative to the original rotation surface. This causes a fatal problem that information reading / writing on the optical disc is incomplete. Also, when taking out the optical disk, the finger often comes into contact with the recording surface on which the touch must be avoided as much as possible, resulting in damage or soiling.

Accordingly, the inventor of the present application has disclosed in Japanese Patent Laid-Open No. 9-40005.
The optical disk container according to No. 8 was devised. The optical disk holder is configured to movably store an optical disk holder that engages with the outer peripheral edge of the optical disk in a box-shaped storage body, and to remove the optical disk very quickly and easily without fear of damaging or soiling the recording surface. In addition to being able to store the optical disk, it is very convenient that the optical disk can be taken out and stored very quickly and easily even with one hand in a car or the like.

It is an object of the present invention to provide an optical disk storage container which can be improved in ease of use, and in which the number of parts can be greatly reduced in order to cope with automatic assembly by a robot. It is the purpose.

According to the optical disk holder of the present invention, the optical disk can be taken out and stored without damaging the center hole which is extremely important for the optical disk, and the recording surface of the optical disk can be damaged. The optical disk holder can be taken out very easily without getting dirty, and the optical disk holder is tilted or rattled by adopting a structure in which the optical disk holder moves in the guide groove formed between the guide member and the bottom plate. It can slide very smoothly in a stable state without being caught halfway. Further, in the structure in which the guide member is provided on the lid side, assembling work becomes extremely easy as compared with a method in which a fixed concave groove is previously formed in the side wall and both sides of the optical disk holder are engaged therewith. Things.

Further, a lid member for covering the opening when the optical disk holder is housed in the box-shaped housing is projected from the leading edge of the optical disk holder in the opening direction. The number of parts of the optical disk holder can be greatly reduced to only three parts, the lid, the bottom plate, the optical disk holder, and this makes it possible to support automatic assembly by robots, greatly streamlining the manufacturing process. Is realized.

When the optical disk holder protrudes from the box-shaped housing, the tip of the optical disk holder is formed so as to be separated from the optical disk and to be bent downward, so that when the optical disk is inserted or removed, the optical disk holder can be removed. This enables smooth insertion and removal of the optical disk without the lid member hindering.

Further, by providing a locking piece for preventing the optical disk from coming off in the upper surface direction and the anti-opening direction of the optical disk holding portion in a region on the inner peripheral wall of the optical disk holding portion on the side opposite to the opening portion, the optical disk can be used. It is stored in a state where it is securely held without moving in the storage body.

Further, by providing a stepped portion which comes into contact with only the outer peripheral edge of the optical disk stored in the optical disk holding portion, the outer peripheral edge which is a non-recording portion in the stored state abuts on the stepped portion, and the optical disk is recorded. By lifting and holding the portion without contacting the optical disk holding portion, there is no possibility that the recording portion of the optical disk is damaged.
