Description

Loading device of optical disc player

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading device for a compact disc (optical disc) player for a vehicle, and more particularly, to allow a drive unit to lock or unlock when a disc is loaded or unloaded. The present invention relates to a loading apparatus of an optical disc player that enables stable disc reproduction even when a vehicle is shaken.

As is well known, a compact disc for converting information such as an audio signal or a video signal into digital data and recording the same on a disc has recently been developed and used simultaneously.

In other words, a device for reproducing information on a compact disc is called a compact disc player (hereinafter, referred to as a CD player), which is mainly applied to a general audio system or developed as a portable player. The spread of so-called automotive CD players is on the rise.

In such a car CD player, unlike the general CD player, when the disc is pushed directly into the disc insertion hole by a predetermined depth, the disc is automatically loaded into the player by the power of the motor. The disc is seated in the drive unit and played at the same time.

In addition, when the ejector button is operated after playback is completed, the ejector is pushed back to a predetermined length by the motor power. In this way, when the disc is pulled out manually and pulled out manually, the disc is ejected. Is complete.

On the other hand, such a CD player for cars, unlike the general CD player is mainly to play the disc while the vehicle is running, so to cope with the shock that the vehicle is rocking to install a drive unit in which the disc is seated and regenerated freely Is common.

However, by installing the drive unit in such a way that the drive unit is freely installed, when the vehicle is impacted during loading and unloading of the disc, that is, when the disc is inserted and withdrawn, contact between the floating drive unit and the disc occurs, thereby causing the surface of the disc. Problems that cause damage and damage to the drive unit occur.

The present invention was created to solve such a conventional problem, and loading of an optical disc player that can prevent the damage of the disc and the damage of the drive unit by preventing the flow of the drive unit during loading and unloading of the disc. The object is to provide a device.

In order to achieve the above object, a loading apparatus of an optical disc player according to the present invention includes a frame having a substantially rectangular frame shape, a turn table positioned on an inner surface of the frame, and a disc seated thereon, and installed freely inside the frame. An optical disc player comprising: a drive unit; and a motor located on the side of the frame; and a plurality of gears rotated by the motor to load and unload discs. A fixing pin member protruding toward the end; The arm lock is pivotally supported on both the front left and right sides of the frame to be rotated while receiving power from the loading gear, and slides forward and backward about both sides of the frame according to the rotation of the arm lock. And a locking device formed of a lever lock having a coupling groove into which the fixing pin member is inserted into both sides of the front and rear sides of the drive unit through the lever lock of the locking device at the time of loading and unloading of the disk. It is characterized in that the fixing pin member to interrupt the flow of the drive unit.

Hereinafter, a preferred embodiment of a loading apparatus of an optical disc player according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a drive unit mounted to a loading apparatus of an optical disc player according to the present invention, and FIG. 2 is a schematic diagram of a drive unit for driving a drive unit of a loading apparatus of an optical disc player according to the present invention, and FIG. b) is an operational state diagram showing a power transmission relationship between loading and releasing a disc to a drive unit of a loading apparatus of an optical disc player according to the present invention. 4 (a) and (b) is an operating state diagram showing a coupling relationship between the fixing part and the locking device according to the present invention.

As shown therein, the present invention includes a frame 2 having a substantially rectangular frame shape.

On the inner surface of the frame 2, a drive unit 1 having a turntable (not shown) on which a disk is seated is installed freely in the x, y and z axis directions.

On the other hand, a motor 4 is provided on the side of the frame 2, that is, on the side frame 5, and a plurality of gear groups that are rotationally driven by the motor are located.

To explain this in more detail, a loading motor gear 41 is installed on the motor 4, and a shaft gear 43 in which the gear pulley 42 is installed on the loading motor gear 41 is meshed with the gear pulley 42. ) And the shaft 51 and the gear transformer 52 are rotatably installed so as to be connected and rotated through the belt.

In addition, the arm idle gear 53 and the gear lead idle gear 54 are coupled to each other through the shaft 51, and the cam is selectively engaged with the gear lead idle gear 54 according to a solenoid operation (not shown). Gear 55 is provided.

On the other hand, the fixing pin members 11 protrude from the four sides on both sides of the above-described drive unit 1 toward the outside, and are locked to selectively interrupt the drive unit 1 having the fixing pin members 11. The device 3 is located on the inner surface of the frame 2.

At this time, the locking device (3) is rotatably supported on the front left and right sides of the frame (2) and the arm lock (7) rotated by receiving power from the loading motor (4), and the arm lock (7) of It is composed of a lever lock (6) which is linked to the end and slidingly conveyed in the front and rear directions of the frame (2) in accordance with their rotation.

On this lever lock 6, a coupling groove 6a is formed so that the fixing pin member 11 extending from the above-described drive unit 1 can be selectively inserted.

Referring to the operating state of the present invention configured as described above are as follows.

First, when the disc is inserted, the insertion of the disc is detected through a detection means (not shown), and at the same time, the loading motor 4 is operated to rotationally drive the loading motor gear 41.

As the loading motor gear 41 rotates, the shaft gear pulley 42, the shaft gear 43, the gear transformer 52, and the like rotate together.

The arm idle gear 53 and the gear lead idle gear 54 are rotated by the rotation of the gear transformer 52, and at the same time the cam gear 55 is rotated according to the solenoid (not shown). As shown in Fig. 1, the loading operation and the unloading operation of the drive unit 1 are performed.

On the other hand, in performing the loading and unloading operation of the disk through the driving of the loading motor 4, the arm lock 7 constituting the locking device 3 is rotated, and at the same time, the lever lock linked to the link ( 6) slide back.

As a result of the rearward movement of the lever lock 6, the fixing pin member 11 extending from the drive unit 1 is inserted into the coupling groove 6a of the lever lock 6, thereby loading and unloading the disk. In this case, the drive unit 1 does not flow.

At the time of loading completion and unloading completion, each of the gear groups described above is operated in the reverse direction by the reverse driving of the loading motor 4, and the lever lock (by the operation opposite to the locking operation of the locking device 3). As the fixing pin member 11 is released from the engaging groove 6a of 6), the drive unit 1 is free to flow.

Therefore, it is possible to prevent the reproduction failure due to vibration in the reproduction process.

As described above, according to the loading device of the optical disc player according to the present invention, by locking the drive unit installed in the frame by connecting four locations of the drive unit that rotates the disk and transfers the pickup, locking and unlocking the drive unit for each operation state By doing so, it is possible to prevent damage to the disk and damage to the drive unit due to external shock or vibration applied to the vehicle during loading and unloading of the disk.
