光ディスクカートリッジである。[Means for Solving the Problems] The present invention provides an optical disc cartridge comprising a retainer for holding the outer periphery of an optical disc and a case for accommodating the retainer holding the optical disc. It is characterized by having a leaf spring that is crimped onto the peripheral surface, and a rod that is supported so as to be retractable from the retainer and operates under pressure on the inner wall of the case when the retainer is stored, and causes the spring force of the leaf spring to act on the optical disc. This is an optical disc cartridge.
[実施例] 以下、本発明の一実施例を図により説明する。[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

。1 and 2, the optical disc cartridge according to the present invention includes a retainer 2 that holds the outer peripheral edge of an optical disc 1.
and a case 3 that houses a retainer 2 holding the optical disc 1. As shown in FIG. 2, one end of a leaf spring 4 is fixed to a partially cut out portion of the inner circumferential surface 2a of the retainer 2, and the free end of the leaf spring 4 is pivotally supported so as to be deformable in the inner radial direction.

けて突出させる。On the other hand, the retainer 2 is provided with a through hole 7 facing the leaf spring 4, and the through hole 7 consists of a large diameter part and a small diameter part, and a stepped part 7a is formed between the large diameter part and the small diameter part. A rod 5 having a large diameter head 5a is inserted into and retracted from the through hole 7, and the free end of the leaf spring 4 biases the head 5a of the rod 5 to close the rear end of the rod 5. 5b is made to protrude toward the inner wall 3a of the case 3.
ロッド5は大径の頭部5aが貫通孔7の段差部7aに当
接するため、貫通孔7から扱は出ることはない。Since the large diameter head portion 5a of the rod 5 abuts against the stepped portion 7a of the through hole 7, the rod 5 does not come out from the through hole 7.

つくことがない。A case will be described in which an optical disc is housed and held in an optical disc cartridge having the above-mentioned configuration. In the embodiment, the outer peripheral edge of the optical disc 1 is held by a retainer 2, and the retainer 2 holding the optical disc is inserted from the insertion opening of the case 3. When the tip 6 of the retainer 2 approaches the bottom 8 of the case 3 (see FIG. 2), the rear end 5b of the rod 5 first comes into contact with the inner wall 3a of the bottom 8 of the case 3. When the rod 5 is brought even closer, the rod 5 stops at that position, the retainer 2 is displaced relative to the rod 5, and the retainer 2 is pushed into the case 3. At this time, the free end of the leaf spring 4 is pressed by the head 5a of the rod 5, and gradually the outer peripheral edge 1 of the optical disc 1
a to move the optical disc 1 toward the inner circumferential surface of the retainer 2 on the insertion opening side. When the tip 6 of the retainer 2 and the bottom 8 of the case 3 come into contact (see Figures 1 and 3),
The optical disc 1 is pressed against the inner peripheral surface of the retainer 2 by a leaf spring 4 and held in a fixed position. Therefore, even if there is a gap between the inner circumferential surface 2a of the retainer 2 and the outer circumferential edge 1a of the optical disk 1, the optical disk 1 is pressed against the retainer 2 by the leaf spring 4 and held in place, so that It won't rattle.
