disk device

Abstract

The invention provides a disc device. The disc device can prevent the charges loaded on a disc, which is inserted in a shell, from being discharged to an electronic part, such as an optical detection elements, etc., or a conduction part of the electronic element. A sliding part (20) of a clamping disc (D) between conveying rollers (15) is fixed at the lower side of a top plate (2d) of the shell (2). On the top plate (2d), a protruding part (8) for retaining the sliding part (20) is bent, and the front end part of the protruding part (8) is more protruded downwards by being compared with the optical detection element (31a). In addition, the protruding part (8) is closer to an insertion part (2e) than the optical detection element (31a), and the disc (D) inserted from the insertion part (2e) passes under the front end part (8a) before reaching the optical detection element (31a), so that the charges loaded on the disc (D) are not discharged to the optical detection element (31a), but are easy to release to the shell (2) from the protruding part (8).

Description

technical field [0001] The present invention relates to a disc device including a conductive protrusion capable of releasing electric charge charged on a disc conveyed inside a case. Background technique [0002] In a disc device loaded with a disc such as an optical disc, countermeasures need to be taken when a hand charged with static electricity approaches or when a charged disc is inserted. [0003] In the disk device described in Patent Document 1 below, a front surface ground is integrally formed on a conductive lower base forming a bottom surface of the disk device. When the operator's finger is close to the front surface barrier, the electric charges on the finger due to static electricity are released from the front surface ground wire to the base, thereby protecting the recording medium and electronic components in the device. [0004] In the disc player described in Patent Document 2, the disc transfer mechanism provided in the housing includes: a metal arm membe...

AI Technical Summary

Problems solved by technology

[0008] The disk device described in Patent Document 1 is provided with a front surface ground on the front surface of the device, so it is possible to discharge the charge charged by the operator's fingers, but when a charged disk is inserted into the device, it is difficult to connect the ground from the front surface. Discharge the disk's charge

[0009] In the disc player described in Patent Document 2, the charge cannot be removed before the charged disc reaches the roller.

For this reason, if an electronic component such as an optical detection element or a terminal of the electronic component, or a wiring layer to which the terminal is connected is provided in the area from the insertion opening inside the housing to the roller, If the disks are exposed opposite to each other, before the disk reaches the roller, the electric charge is transmitted to the electronic components or terminals or wiring layers, and the integrated circuits mounted on the disk player may be damaged.
