KR970051055A - Disk Clamping Device for Optical Player - Google Patents

Abstract

The present invention discloses a disc clamping device of an optical player.

The present invention, the magnet is fixedly installed so that the outer surface is exposed to a predetermined length on the center upper surface of the turn table; A clamp holder positioned above the turn table and having a through hole formed in its center surface thereof; An upper clamper having a conical elastic plate extending from the inner side of the clamp holder to have a flat flange for fixing the through hole of the clamp holder to the outside, and inclined from the inner surface of the flange holder toward the inside of the through hole of the clamp holder. Wow; A lower clamper positioned below the clamp holder and having a flat flange so as to have a shape corresponding to the upper clamper, and a conical elastic plate extending from the flange toward the through hole of the clamp holder; Interposed between the conical elastic plates of the upper and lower clampers, and the iron pieces of the disk connected to each other integrally; to obtain an elastic force through the adsorption force of the iron pieces and the magnet, and the elastic force is seated on the upper surface of the turn table Since the optical disk is pressed and supported, the optical disk can be firmly supported on the turntable.

Therefore, slip friction between the turn table and the optical disk can be prevented. In addition, the structure is very simple, it is possible to reduce the unit cost and improve the assembly workability by reducing the number of parts.
