The operation of the disk mounting device of this embodiment configured as described above will be explained below. now,
As shown in FIG. 8, when the disk 1 is placed on the holding member 2 and an opening/closing button (not shown) is pressed, the drive motor 9 is driven and the drive member 18 moves into the long groove formed in the base 8 integrally with the movable member 7. 8a, it is linearly driven in the direction of arrow A. When the driving member 18 and the movable member 7 move together in the direction of arrow A, and the movable member 7 moves to the position shown in FIG. , the movable member 7 stops moving, but the drive motor 9 continues to rotate, and the drive member 18 stops moving.
The cam portion 18f provided on the drive member 18 engages with the lock arm 21 provided on the base 8 and rotates it in the direction of arrow B, causing the lock arm 21 to move further in the direction of arrow A.
The engaging portion 21a provided at the tip of the movable member 7 is engaged with the lock shaft 31 provided on the movable member 7, and the drive shaft 18g provided on the drive member 18 engages with the sliding arm 5b provided on the rotary cam 5. Since it is engaged and rotated, the cam groove 5a provided in the rotation cam 5
The holding member 2 provided with the sliding shaft 2b that engages with is rotated in the direction of arrow C along the sliding surface provided between the holding member 2 and the pedestal 3, and move it downwards along. This holding member 2
is moved further below the surface of the turntable 25, so that the disk 1 is moved further down from the turntable 25 during the downward movement of the holding member 2.
It is placed on the surface of 5. On the other hand, the cam groove 18c provided at the tip of the driving means has the clamp plate 2.
3 is engaged with the cam shaft 24 provided in the cam groove 18c.
Since the clamp plate 23 is moved along the inner slope and rotated in the direction of arrow D, the clamp plate 2
A clamper 26 provided at the tip of the clamp plate 3 moves in the direction of arrow D together with the clamp plate and is placed on the upper surface of the disk 1 placed on the turntable 25, causing the turntable 25 to press the disk 1. . On the other hand, the biasing gear 1 is engaged with a small rack portion 18d provided on the drive member 18.
9 rotates in conjunction with the movement of the drive member 18, the hook portion 19a of the spring 20 provided on the biasing gear 19 passes through the rotation center of the biasing gear 19, and the spring 20 is attached to the biasing gear 19. The direction of the rotational moment applied by 20 is reversed. That is, the biasing force applied to the drive member 18 is reversed in the direction of arrow X2 shown in FIG. 12B.

When the drive means 18 has moved to the position shown in FIG. 3, the switch A29 is operated by the cam piece 18e provided on the drive means 18 to stop the drive motor 9, thereby completing the operation.

Even when the drive motor 9 stops, the drive member 18 is urged in the direction of arrow X2 by the urging gears 19 and 20, so that the stopped state is reliably maintained.

The shape of the drive member 18 at the portion that slides on the lock arm 21 after the lock arm 21 is rotated in the direction of arrow B is formed approximately equal to the movement locus of the drive member 18. Cam portion 18 provided on drive member 18
After being rotated in the direction of arrow B by f, it contacts the drive member 18 but does not rotate.

On the other hand, when taking out the disk 1, the drive motor 9 is reversed by operating an opening/closing button (not shown), and the drive member 18 is moved in the direction opposite to the direction of arrow A. The clamp plate 23 is rotated in the direction opposite to the direction of the arrow D, and the clamper 26 is moved away from the disk 1. The rotary cam 5 responds to the operation of the drive shaft 18g provided in the drive member 18 in parallel therewith.
is rotated by the spring 6 in the direction opposite to the direction of arrow B, and in conjunction with this, the holding member 2 is rotated in the direction of arrow C.
The disc 1 is lifted from the turntable 25 by moving upward while rotating in the opposite direction. Thereafter, the cam portion 1 provided on the drive member 18
8f is separated from the lock arm 21, and the lock arm 21 is rotated by the wire spring 22 in the direction opposite to the direction of the arrow B, releasing the engagement with the lock shaft 31 provided on the movable member 7. Therefore, the movable member 7 becomes movable and the drive member 18
After moving to the through-hole end 7b of the movable member 7, it moves together with the movable member 7 in the direction opposite to the arrow A. When the movable member 7 moves to the position shown in FIG. The extraction operation of step 1 is completed.

Effects of the Invention As described above, according to the present invention, when the driving member is biased against the movable member and moved together horizontally, and when the movable member stops at a predetermined position, only the driving member moves along the movable member. moves, and in conjunction with this movement, a clamping means consisting of a holding member, a movable plate, a camshaft, and a clamper provided on the movable member so as to be slidable up and down is operated, and in conjunction with this movement, Since the urging force of the urging means is reversed, one drive means can move the movable member in the horizontal direction, move the holding member in the vertical direction, and move the clamping means. . In addition, since horizontal movement and vertical movement are each performed with one movement stopped, reliable operation is possible. Furthermore, by enabling three movements with one linear movement, it is possible to smoothly mount and remove a disk with a simple structure.
