Description

Disc loading device of the deck drive}

The present invention relates to a disc loading apparatus of a disc drive to stably perform disc loading and unloading operations of a disc drive that plays a disc such as an electronic acoustic device (CD), MP3 (MP3).

Disc drives, which are typically electronic sound devices, record information on discs such as compact discs (CDs), CD-ROMs (CD-ROMs), digital video discs (DVDs), DVD-ROMs, MP3s (MP3), etc. A device for reproducing recorded information, which is a component of such a disk drive, includes a CD disk on which a music or video recording is recorded on a turntable while a plurality of parts made of a thin chassis press-wrought iron plate are organically combined with each other. The pickup device is configured to read and reproduce the record recorded on the CD disc. Here, the loading lever for performing the loading and unloading operation is an important component for loading the disc, and an accurate operation is required.

In recent years, it is difficult to use a tray type by requiring a slim design, and thus a slot type for inserting a recording medium directly into a disc drive without a tray on which a recording medium is placed is used. A roller is provided to insert the disc into the disc drive, and when the disc is pushed into the disc drive inlet, the roller rotates and friction with the top surface of the disc causes the disc to be inserted into the disc drive and seated therein, thereby ejecting the disc. In this case, the roller rotates in the opposite direction to discharge the disc through the doorway.

As such, the roller for inserting or ejecting the disk moves and rotates in the direction of the disk only while the disk is inserted or ejected, and returns to its original position after the disk is inserted or ejected. Such an operation is provided on both sides of the disk drive. It is made by the guide plate and the guide hinge.

That is, when the guide plate moves in the insertion or discharge direction of the disc, the guide hinge hanging on one side of the roller pushes the roller in the disc direction.

Accordingly, the prior art that patents the development contents related to the disk loading of the deck mechanism thus far is as follows.

Patent application No. 10-2006-0132944 (December 22, 2006) relates to a disc drive device of the disc drive, which is mounted on both sides of the main chassis so as to be movable in the disc drive direction, lifting guides formed with guide slots, A roller which is mounted on one side of the main chassis with both ends inserted into the guide slot, moves in the disc direction in association with the lifting guide, and rotates in contact with the disc, thereby extracting the disc; Is installed so as to be rotatable in the main chassis in connection with one side of the guide, so that the roller is linked to the lifting guide to move along the guide slot, the elastic to further provide an elastic force in the disk direction to the moved roller By including a guide hinge provided with a member, the rotation angle of the guide hinge is reduced There is an advantage that can be implemented more slim disc drives enemies. Patent application No. 10-2004-0112362 (December 24, 2004) relates to a disc drive device and a method of the disc drive, and is installed on the main base and the forward and reverse rotation of the loading motor to provide power for the disc transfer ; A roller which is installed on a roller link that rotates about a hinge axis on the main base and is rotated by a driving force of the loading motor and is in close contact with one surface of the disc to transfer the disc; A clamp plate provided at the front end with a clamp to fix the disk to a turntable installed on the main base and to be moved up and down about a hinge axis of the main base; A stopper provided to protrude to a lower surface of the clamp plate and regulating a position at which a disc of relatively small diameter is loaded; A cam lever configured to selectively receive and drive a driving force of the loading motor, and to lift and lower the hinge plate and rotate the roller link; The roller link is rotated at an angle before the clamp plate is lowered by the cam lever during the loading operation of the disk, so that the roller is separated from the lower surface of the disk so that the relatively large disk does not interfere with the stopper. Patent application No. 10-2005-0079350 (August 29, 2005) discloses an optical recording and reproducing apparatus that can prevent the disc from escaping to the outside during operation, it is installed in the main body having an inlet, The deck equipped with the spindle motor and the optical pickup unit, the tray installed in the main body to enter and exit through the inlet, the loading device for entering and exiting the tray, and the inlet side to close the inlet after the tray enters the main body. It includes a safety door that is opened and closed by the operation.

In the configuration of such a slotted disk drive, the mechanism of accurately loading the disc on the turntable playing the disc and unloading the finished disc is the most complicated, so that the overall volume is determined by their configuration, as well as their function and performance. The quality of the product is determined accordingly. Until now, the disc loading device has a guide hinge for tightly adhering the roller to the disc. The guide hinge is interlocked with the guide plate to rotate the roller at an angle, and then presses the roller onto the disc. Since the guide hinge is rotated more than a certain angle in returning the roller to its original position, the height of the disk drive capable of such rotation should be ensured, thereby increasing the volume for securing the overall space and making the disk drive slim. Got done In particular, the various levers and their combinations that are configured to operate the rollers are not perfect so that the levers may be out of position during operation or cause an error in operation, causing problems.
