Abstract

The present invention relates to an optical disc device, which realizes cost reduction and simplification of assembly by fixing an optical pickup and a feed rack without a connecting member. Since the elastic holding part is arranged on the feed rack (4), the elastic holding part prevents looseness between the optical pickup (3) and the feed rack (4) , so as to maintain the positioning of the optical pickup in the A-B direction, and because the hook is provided on the holding part, it can also be used to maintain the positioning in the C-D direction, and the feed rack (4) Positioning pins are provided to maintain positioning in the EF direction, and the feed rack ( 4) Press against the optical pickup (3), thereby forming a structure in which the optical pickup (3) and the feed rack (4) can be fixed without connecting pieces.

Description

technical field

[0001] The present invention relates to an optical disc device which has a simple structure by reducing the number of parts. Background technique

[0002] The pickup driving mechanism for recording and reproducing on the optical disc is composed of a guide part, an optical pickup, a feed rack and a feed gear. The rack is firmly connected to the optical pickup and driven by the feed gear. For recording and reproduction of an optical disc, it is necessary to precisely control the feed amount of the optical pickup, and a structure to absorb the meshing gap between the feed gear and the feed rack is required. Usually, the rack portion of the feed rack is formed of resin, and the bending of the rack portion increases the meshing amount on the pitch line by virtue of the elasticity of the resin, thereby absorbing the meshing gap. And, in order to precisely control the feeding amount of the optical pickup, it is necessary to use a connecting member to fix the opti...
