    In order to achieve the object of the present invention as described above, the disk conveying means for mounting and conveying the disk, and the release of the clamping state of the disk by releasing the amount of force applied to the disk according to the direction of movement of the disk conveying means A disk unclamping apparatus for a disk drive is provided, comprising a means.
    The release means is provided at a position fixed relative to the disk transfer means, the guide portion is formed to be inclined long in the direction in which the disk is moved into the inside of the disk drive, the disc at the tip of the guide portion to the outside of the disk drive It is formed perpendicular to the moving direction is composed of a locking portion for pushing the disk moved to the outside, the disk transfer means has a projection hole for protruding in accordance with the movement of the disk transfer means to the locking portion of the release means to push up the disk It is formed on one side.
    According to such a configuration, the disk is unclamped from the clamp stage by the operation of the tray protruding to the outside of the drive, thereby making it easier to take out the disk from the clamp stage.
    Hereinafter, with reference to the accompanying drawings a preferred embodiment of the disk clamp device of the disk drive according to the present invention as described above in detail as follows.
    Figure 2 is a plan view showing a schematic configuration of a disk drive with a disk unclamping device according to the present invention, Figure 3 is a cross-sectional view showing the main configuration of the disk unclamping device according to the present invention, Figures 4a, 4b, 4c It is an operation state diagram for explaining the operation of the disk unclamping device according to the present invention. 5 is a front view illustrating a relationship between a case and a tray in a general disk drive.
    As shown in these figures, the disk D is mounted and a tray T for conveying the disk D is installed in the case C in a retractable manner.
    The tray T is provided with a spindle motor (not shown) for rotating the disk D, a component for transferring an optical pickup (not shown), and a component for ejecting the tray T. And, one side of the tray (T) is formed with a protrusion hole (10). Such a protruding hole 10 is to project the one-way elastic member 20 to be described below to contact the disk (D). The position of the protruding hole 10 preferably corresponds to the outer peripheral edge of the disk D such that the data recording surface of the disk D does not come into contact with the one-way elastic member 20 to be described below.
    One side elastic member 20 is provided at one side of the case C. The position in which the one-way elastic member 20 is installed is any place on the path along which the protrusion hole 10 moves according to the movement of the tray T. Especially, the front-end | tip part of the said case C is the most preferable.
    The one-way elastic member 20 serves to release the clamping state of the disk D by varying the magnitude of the force applied to the disk D according to the moving direction of the tray T. The one-way elastic member 20 is composed of a guide portion 21 and the engaging portion 22.
    The guide portion 21 is connected to the case (C) and is formed to be inclined long in the direction in which the disk (D) is moved into the case (C). In addition, the locking portion 22 is provided at the front end of the guide portion 21 and is formed substantially perpendicular to the direction in which the disk D is moved out of the case C.
    The operation of the present embodiment having the configuration as described above will be described in detail with reference to FIGS. 4A, 4B, and 4C.
    First, it will be described that the disk D is moved into the case C. As shown in FIG. In this case, when the tray T is moved and the protruding hole 10 comes to the position of the one-way elastic member 20, the one-way elastic member 20 is shown in FIG. 4A. It is pressed by the lower surface of (T) and protrudes into the protrusion hole 10. In this case, however, the disk D moves from the base of the guide 21 toward the tip, so that the disk D contacts the top of the guide 21 in the direction of the base of the guide 21. do. Therefore, the disk (D) is moved while pressing the one-way elastic member 20 in the direction of the arrow b so that the one-way elastic member 20 does not apply a force to the disk (D) clamping state of the disk (D) It does not change
    Therefore, the disk D is moved to the inside of the case C by the tray T while being clamped to the clamp table 3, and the subsequent operation is performed. On the other hand, the one-way elastic member 20 is in the state of FIG. 4A during the subsequent operation.
    The case where the disk D moves out of the case C by the tray T will be described. In this case, as shown in FIG. 4A, the one-way elastic member 20 is pressed by the tray T, and the protrusion protrudes at the position of the one-way elastic member 20 by the movement of the tray T. When the ball 10 comes, the one-way elastic member 20 is protruded into the protrusion hole (10).
    In this case, the disk D comes into contact with the one-way elastic member 20 from the engaging portion 22 provided at the front end portion of the one-way elastic member 20, and the one-way elastic member moves as the disk D moves. The member 20 exerts a force F on FIG. 4C against the disk D. FIG.
    As such, the force F is applied from the one-way elastic member 20 to the disk D. The force applied by the disk D to the one-way elastic member 20 is the guide portion 21. And the engaging portion 22 do not act as a force to deform the one-way elastic member 20, but act as a reaction force against the disk (D). That is, the one-way elastic member 20 is slightly lifted in the direction of the arrow d, the disk (D) mounted on the clamp stand 3 is caught by the engaging portion 22 is subjected to a force.
    The clamping state of the disk D is released by the force F acting on the disk D as described above. Therefore, the user only needs to lift the disk D while the tray T is completely protruded to the outside.
    As described in detail above, an unclamping apparatus of a disc drive has a unidirectional stop member that does not exert a reaction force on the disc when the disc is moved into the drive by the shape thereof, and does not apply to the disc when the disc is moved out of the drive. It is configured to release the clamping state by acting a reaction force to the effect that the user does not have to perform a separate unclamping operation when removing the disk from the tray.
