At this time, the clamp 3 is mounted on the chassis main body 1 with a spring 24 so that the lever 4 always slides while being in close contact with the inclined guide 14 of the slider 10.

In this case, when the lever 4 of the clamp 3 is coupled to the locking groove 25, the disk is clamped, and when the lever 4 is released from the locking groove 25, the clamp 3 is lifted from the disk. .

The mechanism for loading and clamping the disk according to the present invention configured as described above operates as follows.

Disk insertion operation; Referring to FIG. 2 schematically showing the engagement side view of FIG. 1, when the disk 70 is first pushed into the guide roller 2, the drive source 40 is driven by a predetermined sensing device (not shown). Then, the idler gear 23 connected by the drive source 40 and both gears 45 is rotated, and the driven gear 22 and the pinion 21 are rotated at the same time. At this time, the solenoid 50 is not operating, the operation plate 30 is rotated counterclockwise by the spring 60 to the pinion 21 and the rack gear 11 of the guide pin hole 19. Isolate. On the other hand, the free space is formed by the separation groove 12 formed in the guide claim hole 19, the pinion 21 is securely separated from the rack gear (11). Accordingly, the disk 70 is inserted by the rotation of the guide roller 2 and seated on the spindle motor (not shown).

Disk clamping operation; 1, 3 and 4, the slider 10 is moved slightly to the left by push means (not shown) to short-circuit the switch lever 91 and the metal piece 93, and thus the solenoid ( When the operating rod 51 is operated in the direction of the arrow when 50) is turned on, the pinion 21 is engaged with the rack gear 11 while the operating plate 30 is rotated clockwise. At the same time, the pinion 21 driven from the drive source 40 rotates clockwise to slide the slider 10 to the left. At this time, the roller guide pin 80 is lowered along the inclined long hole 15, the guide roller 2 is rotated so that the driven gear (9) is separated from the idler gear (23), the lever (4) of the clamp (3) Slides to the inclined guide portion 14 of the slider 10 and the clamp 3 rotates counterclockwise. As shown in FIG. 4, the lever 4 is coupled to the locking groove 25. The clamp 3 then clamps the disk. When the clamping of the disk is completed as described above, the switch lever 91 is separated from the metal piece 93 so that the solenoid 50 is turned off, and the operating plate 30 is rotated counterclockwise by the spring 60 to form a fourth. As shown in the figure, the pinion 21 is separated from the rack gear 11. At this time, the pinion 21 is separated by the free space of the separation groove 13 of the guide holder 19 is reliably made.

Disk ejecting operation; 1 and 5, when the slider 10 is slightly moved to the right by push means (not shown), the switch lever 91 is short-circuited with the metal piece 93 so that the solenoid 50 is turned on to operate the rod. When the 51 is operated in the direction of the arrow, the operating plate 30 is rotated in the clockwise direction and the pinion 21 is engaged with the rack gear (11). At the same time, the pinion 21 driven from the drive source 40 is rotated counterclockwise to move the slider 10 to the right. At this time, the lever 4 of the clamp 3 is released from the locking groove 25 of the inclined guide portion 14 so that the clamp 3 is lifted from the disk and the clamping is released. At the same time, the guide roller pin 80 is inclined. The driven gear 9 installed on the guide roller 2 is guided to the upper side of the long hole 15 so as to rotate in the direction approaching the idler gear 23. As soon as the slider 10 is driven by driving the pinion 21 and the solenoid 50 is turned off, the operation plate 30 is rotated by the spring 60 to rotate the pinion 21 from the rack gear 11. The guide roller 2 is rotated while the driven gear 9 is engaged with the idler gear 23 so that the disc is discharged.

As described above, the mechanism for loading and clamping the disk according to the present invention includes a guide roller 2 for inserting and ejecting the disk according to the movement of the slider 10 and a clamp 3 for clamping and releasing the disk. By selectively operating the operation, the structure is simple and the operation is made sure.

It goes without saying that one skilled in the art can, of course, make many variations in addition to the embodiments described above.
