It is controlled on/off by d. 3
5, 36.37 is the above-mentioned driven boob IJ 10 + transmission gear 11. This is a shaft that rotatably supports the drive gear 12.

The operation of the disk loading 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 the opening/closing button is pressed, the drive motor 9 is driven and the drive member 18 is moved together with the movable member 7 to the base 8. It is linearly driven in the direction of arrow A according to the provided long groove 8a. 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 part 10 -
Although the material stops moving, the drive motor 9 continues to rotate, and the drive member 18 moves further along the movable member 7 in the direction of the arrow.
The cam portion 18f provided at the tip of the lock arm 21 engages with the lock arm 21 provided on the base 8 and rotates it in the direction of arrow B. The drive shaft 18g provided on the drive member 18 engages with the lock shaft 31 provided on the drive member 18, and the drive shaft 18g provided on the drive member
Since it engages with the provided sliding arm 6b to rotate it, the holding member 2 provided with the sliding shaft 2b that engages with the cam groove 5a provided in the rotating cam 6 is connected to this holding member 2. It is rotated in the direction of arrow C along a sliding surface provided between the pedestal 3 and moved downward along the sliding surface. Since the holding member 2 is moved further below the surface of the turntable 25, the disk 1 is placed on the surface of the turntable 25 during the downward movement of the holding member 2. On the other hand, a cam shaft 24 provided on the clamp plate 23 by 11 mm engages with the cam groove 180 provided at the tip of the driving means, and moves along the slope in the cam groove 18C, thereby clamping the clamp plate 23. Since the plate 23 is rotated in the direction indicated by the arrow, the clamper 26 provided at the tip of the clamp plate 23 moves together with the clamp plate in the direction indicated by the arrow, and is placed on the upper surface of the disc 1 placed on the turntable 26. and the disc 1 is placed on the turntable 25.
Press down. When the drive means 18 has moved to the position shown in FIG.
The operation is completed by stopping .

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, so that the lock arm 21 is the driving member 18
After being rotated in the direction of the arrow B by the cam portion 18f provided in the cam portion 18f, it contacts the drive member 18 but does not rotate.

On the other hand, when taking out the 7' isk 1, the drive motor 9 is reversed by operating an opening/closing button (not shown), and the drive member 18 is moved in the opposite direction to the direction indicated by the arrow. In the groove 180: the above clamp plate 23
is rotated in the direction opposite to the arrow direction to move the clamper 26 away from the disk 1. Parallel to this, the rotating cam 5 is rotated by the spring 6 in the direction opposite to the arrow B direction in response to the operation of the drive shaft 18g provided on the second drive unit 1B. The holding member 2 rotates in the direction opposite to the direction of the arrow C and moves in the - direction to lift the disc 1 from the turntable 25''. Thereafter, the cam portion 18f provided on the drive member 18 separates from the lock arm 21, and the lock arm 21 moves as indicated by the arrow B.
The movable member 7 is rotated by the wire spring 22 in the opposite direction to release the engagement with the lock shaft 31 provided on the movable member 7.

Therefore, the movable member 7 is movable, and after the drive member 18 has moved to the through-hole end 7b of the movable member 7, it moves integrally 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. 1, the pedestal 3131 knee i moves together with the movable member 7
The abutment piece 3d provided at the switch B 30 is operated to stop the drive motor 9, thereby completing the ejecting operation of the disk 1.

Effects of the Invention As described above, according to the present invention, when the driving member is biased against the movable member to move horizontally together, 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 clamp 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.
One driving means can move the movable member in the horizontal direction, the holding member in the vertical direction, and the clamping means. Furthermore, since the horizontal movement and the vertical movement are performed while one of the movements is stopped, reliable operation is possible. Furthermore, by making three movements possible with one linear movement, it is possible to smoothly mount and set up a disc with a simple structure.
