Embodiment Construction

[0052] In the following, it will be based on Figures 1 to 13 Embodiments of the present invention are described.

[0053] (Overview of disc player)

[0054] figure 1 Shows a view (chassis part) of a disc player, in which the display of different types of drive mechanisms is omitted. figure 1 (a) is a plan view, figure 1 (b) is the front view, and figure 1 (c) is a right side view. Disc player main body 1 (main body chassis 11 such as figure 1 shown) is arranged in the chassis base 101. The main body chassis 11 is elastically supported by coil spring dampers 102 (distributed at three positions) provided on the bottom surface end of the main body chassis 11 in the chassis base 101 . A disc loading slot 20 is formed on the front surface of the chassis base 101 . The disc loading slot 20 is provided with a right disc guide 2R and a left disc guide 2L formed of resin, and the disc loading slot 20 is shaped like a T-shape. The distance between the right end of the upper su...

Abstract

A control plate (21) is disposed on the lower surface behind the upper plate of a chassis base (101). Disks (D1, D2) are each inserted while contacting the contact guide portion (P1) of the control plate (21). A stop portion (P2) is formed at a position inwardly beyond the contact guide portion (P1). The peripheral surface of a transfer roller (5) is positioned in the advancing of the disk (D1, D2) advancing while contacting the upper surfaces of disk guides (2R, 2L) for a disk loading port (20) and contacting the contact guide portion (P1). And the stop portion (P2) is located at a place corresponding to the direction of a tangent, included in the tangents to the peripheral surface at places deviated from the advancing direction of the disks (D1, D2), passing through the contact guide portion (P1).

Description

technical field [0001] The present invention relates to a disk player for playing back disks (recording media) such as CDs or DVDs and other media. Background technique [0002] Generally, portable disc players and car mounted disc players have been devised. In recent years, disk players capable of playing back 8cm and 12cm disks have been designed (see JP-A 2001-143352). Furthermore, disc players capable of playing back DVDs as well as CDs have also been designed. [0003] In such disc players, a mechanism capable of preventing foreign substances such as telephone cards or others from being inserted into the main body of the player is required. [0004] Also, in such disc players, during the ejection process, an operation of raising the clamper holding the disc is performed, while the clamper is positioned by abutting its top end side (the part raised to the highest) against the chassis top plate. In some cases, the gripper may bend if the abutment force is high. [000...
