Problems solved by technology

[0004] However, since the above-mentioned disk device has the above-mentioned structure, when the bonded disk is inserted into and removed from the disk device, when the contact portion of the disk comes into contact with the outer peripheral surface of the bonded disk, the adhesive leaked from the outer peripheral surface will be formed. The friction generated between the contact surfaces increases the operating load, so there is a problem that the bonded disk cannot be inserted and removed smoothly, and in the worst case, it may cause malfunction.

Abstract

A guide flap 3 is nearly a flat member, and a pair of disk guide parts 4, 5 is formed at its both sides. Each inside of the disk guide parts 4, 5 is abutted on an outer periphery of the disk M to form disk abutting parts 4a, 5a for supporting it. The disk abutting part 4a is formed into the uneven shape having a plurality of grooves extended in the direction of the thickness of the disk M.

Description

【Technical field】 [0001] BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a disc device for optically recording and reproducing video and audio information, etc., on a disc such as a DVD (Digital Video Disc). 【Background technique】 [0002] A disk device for recording and reproducing disks such as DVDs, including: a frame with a disk insertion slot, guide pieces fixed near the insertion slot of the frame, and guiding the disk, and provided between the guide pieces to be guided. The rollers with high disk transport force, the roller seat supporting the rollers, and the disk size selection lever for judging the size of the disk. On the guide piece, the roller base and the disk size selection lever, there are disk contact portions that contact and support the outer peripheral surface of the disk at positions facing the disk conveyance path. The contact portion of each disk in the conventional disk device has a surface that contacts in the thi...
