Radiating device used in optical memory/reading apparatus

Abstract

A heat radiation device in optical storage / fetch unit used to store / fetch data on optical storage media consists of a holding mechanism for holding and rotating the optical storage media, fan blade set being installed in the holding mechanism and being brought to rotate to generate airstream for achieving heat radiation effect.

Description

technical field [0001] The invention relates to an optical storage / reading device, especially a heat dissipation device used in the optical storage / reading device. Background technique [0002] Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a known optical disc player 2 . An optical storage / reading device such as a CD player (VCD player, DVD player) 2 includes a pickup head 4, a circuit board 6, a holding mechanism 34... and other components. [0003] The read / write head 4 is used to read the data on the surface of the optical storage medium (not shown) placed in the optical disc player 2, and the common optical storage medium is an optical disc. The read data needs to be calculated and processed by the chip 10 on the circuit board 6, so that the subsequent CD player 2 can play the processed data in the form of video / audio multimedia. [0004] Please refer to FIG. 2 . FIG. 2 is a schematic diagram of a clamping mechanism 34 in the known technology. The clamping...
