BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp device of an optical disk player, and more particularly, to a clamp device of an optical disk player that can reduce the thickness of the optical disk player by reducing the height required for the operation of the clamp device.

The optical disc reproducing apparatus has a clamp device for fixing the disc to the upper surface of the spindle for reproducing the inserted disc.

1A and 1B show a conventional clamping device, FIG. 1A is a side view of the clamp device in an unclamped state, and FIG. 1B is a side view of the clamp device in a clamping state.

As shown in these figures, the conventional clamping device is a clamping arm 32 hinged by the hinge portion 33 to the optical disc reproducing apparatus so as to be rotatable between the clamping position (FIG. 1B) and the unclamping position (FIG. 1A). And a clamping holder 31 which is fixed to the lower end surface of the clamping arm 32 so that the disk 20 seated on the upper surface of the spindle 10 can be pressed when the clamping arm 32 is in the clamping position. It consists of.

Referring to the operation, when the disk 20 is seated on the upper surface of the spindle 10, the clamping arm 32 is rotated from the unclamping position (Fig. 1a) to the clamping position (Fig. 1b), and the clamping holder 31 An upper surface of the spindle 10 fixes the disk 20.

Then, when the disk 20 is attached and detached, the clamping arm 32 is moved to the unclamping position (Fig. 1A). However, when the clamping arm 32 moves to the unclamping position (Fig. 1A), the height H1 of the end of the clamping holder becomes L x sin θ. Therefore, since the overall thickness of the disk drive must be higher than the height H1, it acts as a limiting factor in forming the drive thinly, making it difficult to form the drive thin.

The present invention has been made to solve the above problems, and an object thereof is to provide a clamp device that can reduce the height of the drive.

In order to achieve the object as described above, the present invention comprises: a clamping arm having one end hinged to the optical disc reproducing apparatus and rotating; A clamping holder hinged to the clamping arm, the clamping holder clamping or unclamping the disk while vertically moving in conjunction with the rotational movement of the clamping arm; Provided are a clamping device for an optical disc reproducing apparatus.
This is for the clamping holder hinged to the clamping arm to convert the rotational movement of the clamping arm into vertical up and down movement so that it can be clamped or unclamped in the vertically upward direction of the disk.

And a stopper device for allowing said clamping holder to apply a constant compressive force to said disk when said clamping arm is in the clamping position; It is preferable to comprise more.

The stopper device may further comprise a clamping arm stopper protruding from the clamping arm; A clamping holder stopper protruding from the clamping holder to engage the clamping arm stopper; It is effective to include.

And a torsion spring, one end of which is coupled to the clamping holder and the other end of which is coupled to the clamping arm to prevent the clamping holder from rotating excessively toward the disk; It is preferable to comprise more.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, in describing the present invention, a detailed description of known functions or configurations will be omitted in order not to disturb the gist of the present invention.

In addition, the same reference numerals are given to the same and the same components as those described above, and detailed description thereof will be omitted.

2 to 5 show the structure of one embodiment of the present invention, FIG. 2 is a side view of the clamping device of the optical disc player in an unclamping position, and FIG. 3 is a side view of the clamping device of FIG. 2 in a clamping position, FIG. 4 is a side view of the clamp holder of FIG. 2, and FIG. 5 is a side view of the clamp arm of FIG.

As shown in these figures, the clamping device of one embodiment of the present invention is rotatable between a clamping position for clamping the disk 20 (FIG. 3) and an unclamping position for clamping the disk 20 (FIG. 2). The clamping arm 140 is hinged to the optical disk player, the clamping holder 130 is hinged to the clamping arm 140 to clamp the disk 20, and the clamping arm 140 is clamped. When in position (FIG. 3), the stopper device allows the clamping holder 130 to exert a constant compressive force on the disk 20, and the clamping holder 130 being excessively rotated toward the disk 20. One end is coupled to the clamping holder 130 to prevent the other end is configured to include a torsion spring 150 coupled to the clamping arm 140.

The clamping arm 140 includes a main body hinge portion 142 hinged to the optical disk player, a holder hinge portion 141 hinged to the clamping holder 130, the main body hinge portion 142 and the holder hinge. It includes a spring holder 144 formed between the branch portion 141 and a clamping arm stopper 143 protruding from the lower surface of one end of the opposite side of the main body hinge portion 142 around the holder hinge portion 141. do.

The clamping holder 130 is an arm hinge portion 131 formed to be coupled to the holder hinge portion 141, a holder stopper 132 formed by bending the lower portion of the arm hinge portion 131, and the holder It is configured to include a spring holder 133 protruding to the side of the stopper 132.

The stopper device includes the clamping arm stopper 143 and the holder stopper 132.

The torsion spring 133 is inserted into the holder hinge portion 141 and the arm hinge portion 131 to the torsion portion, both ends are installed so as to be supported by the spring holder (144, 133), respectively.

Hereinafter, the operation of one embodiment of the present invention will be described.

When the disk 20 is seated on the upper surface of the spindle 10, the clamping arm 140 is rotated from the unclamping position (Fig. 2) to the clamping position (Fig. 3) by a separate driving device, and the clamping holder 130 ) And the upper surface of the spindle 10 is fixed to the disk (20). At this time, the clamping arm stopper 143 and the clamping holder stopper 132 abut each other, thereby preventing excessive rotation of the clamping holder 130, thereby applying an appropriate pressure to the disk 20.

In addition, when the disk 20 is attached or detached, the clamping arm 140 moves to the unclamping position (FIG. 2). At this time, the clamping holder 130 is rotated toward the spindle around the hinge parts 141 and 131 by the hinge parts 141 and 131, which is supported by the torsion spring 150. Therefore, as shown in FIG. 2, the clamping holder 130 is kept horizontal, and the inclination of the clamping holder 130 is adjusted according to the spring strength of the torsion spring 150. Therefore, the height of the end of the clamping holder 130 is L1 x sin θ, the height is reduced by L2 x sin θ compared with the conventional clamping device.
That is, the hinge rotational movement of the clamping arm 140 may be converted to the vertical vertical movement of the clamping holder 130 to clamp or unclamp the disk. Thus, the height of the end of the clamping holder can be reduced.
Therefore, the drive can be formed thin.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.

The present invention provides a clamp device that can reduce the height of the drive.
