Embodiment １

[0025] figure 1 It is a perspective view of the appearance of the optical disk player of the first embodiment. The housing 1 is composed of a metal upper substrate 2 and a lower substrate 3 . Ears with device mounting holes 1a are provided on the outer sides of the upper frame of the upper base plate 2 and the lower base plate 3 respectively, and the ears are overlapped to ensure sufficient strength even if the thickness of the base plate is thin. An insertion port 4 for inserting an optical disc is provided on a side surface of the lower substrate 3 . Furthermore, a playback substrate 7 having a turntable 5 and a signal read / write head 6 is provided inside the housing 1 . On the upper base plate 2, an elongated protrusion 2a is formed at the rear side of the turntable 5 as viewed from the insertion port 4, and a disc stopper 8 for mounting the small-diameter optical disc A on the turntable 5 is mounted therein.

Abstract

The invention relates to a compact disc player. The compact disc player comprises a playing base board which is supported in a frame body and can move freely, a conveying roller, a compact disc induction device which is pushed to rotate by a compact disc inserted into an insertion port, a compact disc stop device which has a long shaft and abutting parts arranged at two ends of the long shaft, a first trigger part which rotates when a small-diameter compact disc is made to stop at a mountable position on a rotation disc through the compact disc stop device, a rack part which receives movement of the first trigger part and power of a motor to move, a cam part which is linked with the rack part and enables a clamping disc to depart from the rotation disc, and a moving part which receives rotation of the compact disc induction device and moves according to the outer diameter of the compact disc, wherein the moving part is provided with a clamping part and an abutted part which is clamped with an abutting part, and the cam part or a motion part which is linked with the cam part at a moving terminal of the cam part is provided with a clamped part in abutting connection with the clamping part. The compact disc has a property of simple structure of a stop releasing mechanism.

Description

technical field [0001] The present invention relates to an optical disc playback device, and more particularly, to an optical disc playback device having a stopper for stopping an optical disc when a transport roller transports the optical disc to a mountable position on a turntable. Background technique [0002] There is known an optical disc player provided with a stopper for stopping an optical disc transported by transport rollers at a mountable position on a turntable. The optical disk playback device supports the playback substrate movably inside the frame body, thereby improving the shock resistance. In the disc playback device disclosed in Japanese Patent Application Laid-Open No. 2005-302217 (hereinafter referred to as Patent Document 1), the following components are provided: a transport roller for transporting the disc from the disc insertion port to the channel on the playback substrate; A detection lever; a stopper 8a that stops the small-diameter optical disk ...
