Loading device for car optic disc player

Abstract

A loading device of a compact disk player for an automobile is disclosed. The loading device has a roller provided at an inlet to be rotated by a driving motor, a roller arm supporting the roller to be moved up and down, the roller arm being divided into a first roller arm and a second roller arm which are connected to a connecting shaft to be in the same plane and separately rotated about the connecting shaft by a certain angle, and a spring interposed between the roller arm and a player body to bias the roller upwardly by its restoring force, whereby a disk inserted through the inlet is loaded into the player body and seated on a turntable. The loading device of the present invention has constant ejecting force, thereby preventing ejecting errors and thus improving performance and reliability of products.

Description

technical field [0001] The present invention relates to an automotive compact disc player and, more particularly, to a split roller arm that includes two split roller arms adapted to operate independently of each other to minimize errors when loading a disc into the compact disc player Car CD player loading device. Background technique [0002] Generally speaking, a car optical disc player is an appliance that plays back data recorded on an optical disc through an optical system. [0003] This car CD player includes a turntable on which the disc is placed, a loading unit for pulling back a disc inserted into an insertion slot and placing the disc on the turntable, a driver for turning the turntable, a A clamping unit to prevent the disc from moving during the rotation of the turntable, an optical head to write data to and read data from the disc while moving radially on the disc, and an optical head to move the optical head back and forth head conveyor.

AI Technical Summary

Problems solved by technology

[0016] However, since the conventional loading device of the car CD player includes a roller arm 50 composed of a single component, when the roller arm 50 is deformed, or a part of the upper and lower frame assemblies 30 and 20 is deformed, the roller 40 cannot be aligned with the upper frame assembly. The frame assembly 30 is positioned parallel to

Therefore, since the roller 40 cannot contact the disk at a parallel position during the loading of the disk, errors occur in loading and ejecting the disk.

[0017] That is, if the roller 40 cannot be positioned parallel to the upper frame assembly 30, since the roller 40 is in contact with a part of the disk "D", and the symmetrical part of the roller 40 is not in contact with the disk "D", the disk cannot be moved. Loads smoothly into the player body 10 and turns in place, causing ejection errors

[0018] Furthermore, if the disk cannot contact the roller 40 in a parallel position, then due to insufficient ejection force, defective products result, reducing performance and reliability
