Referring to the operation and effects of the present invention configured as described above in more detail.

First, the tray 11 is moved up and down to match the height and position of the disc holder 37 of any storage end of the disc storage unit 15 or the disc regeneration unit. The tray 11 is moved vertically by the step groove 42 formed in the step plate 41 by the horizontal movement of the step plate 41 by the rotation of the selection gear 21 by the driving force of Will be.

At this time, the rotational force of the selecting gear 21 is transmitted to the cam gear 22. As shown in FIG. 6, the tray 11 moves to the storage end adjacent to the storage end or the disk at the lowest storage end. While moving to the holder 37, the cam plate 24 is moved to the left side by the restoring spring 26 so that the tray portion 11 is aligned with the height of the storage end or the disc holder 37. Then, the protruding portion of the cam 23 rotating in accordance with the cam gear 22 is moved by the cam plate 24 by moving the protruding pin 24 'of the cam plate 24 to the right. The plate 25 is moved horizontally to the right.

As described above, when the loading plate 25 is horizontally moved to the right as shown in FIG. 4, the first and second torsion springs 27 and 28 rotate, and the first torsion spring 27 is rotated. When rotated, the first pinch roller bracket 29 moves to the right while rotating counterclockwise, and when the second torsion spring 28 rotates, the second pinch roller bracket 30 moves to the left while rotating clockwise. The mini disk MD can be compressed.

In the same manner as described above, the tray 11 is vertically moved so that the height of the tray holder 11 or the disc holder 37 of the disc reproducing unit coincides with the height thereof, and thus the first and second pinch rollers. The mini disk MD is loaded or unloaded between the tray portion 11 and the disc accommodating portion 15 or the disc holder 37 while the mini disc MD is compressed by the 12 and 13. This is due to the loading motor 17.

That is, when the loading motor 17 is driven in the disc loading direction while the first and second pinch rollers 12 and 13 compress the mini disc MD as described above, the kinetic force of the loading motor 17 is reduced. The first and second pinch rollers 12 and 13 are transferred to the first and second pinch rollers 12 and 13 through a plurality of power transmission gears and first and second press-fit gears 8 and 9. Rotate in the rotational direction to be symmetrical with each other to load the mini-disk (MD).

That is, the first pinch roller 12 rotates in the clockwise direction and the second pinch roller 13 rotates in the counterclockwise direction so that the mini disc MD is mounted on the disc housing 15 or the disc holder in the tray 11. Loaded with 37.

At the same time, when the loading motor 17 is rotated in the disc loading direction, the driving force of the loading motor 17 is the first bevel gear 31, the second bevel gear 32, a plurality of power transmission gears It is transmitted to the first rubber roller 14 through the gears and the press-in gear 33 of.

In other words, the first rubber roller 14 is rotated in the disc loading direction by the press-fit gear 33, and thus the mini-disc roller is not driven by the first pinch roller 12 and the second pinch roller 13. Move it. Of course, while the first rubber roller 14 is rotated to move the mini disk, the second rubber roller 16 is rotated by the mini disk and guides the movement path of the mini disk.

In this case, when the mini disc MD is inserted into the tray unit 11, the mini disc MD is often misinserted. When the 34 is turned on, the loading motor 17 rotates in the loading direction so that the mini disk MD is moved to the tray portion 11 by the first and second pinch rollers 12 and 13 and the first rubber roller 14. It is seated on).

At this time, the side of the mini-disc MD turns on the first switch 34 and the first switch 34 is turned off for a while by the loading groove 4 formed on the side of the mini-disc MD. When the first switch 34 is turned on again by the side of the mini disk MD, it is recognized that the mini disk MD is normally inserted, and the output waveform of the first switch 34 is as described above. If it is not on-off-on, it is recognized that the mini-disc (MD) is misinserted.

In addition, when the mini disk MD is inserted, the third switch 36 is turned on. When the mini disk MD is inserted upside down, the third switch 36 is turned on and off. ) Can detect misinsertion.

In addition, when the mini disc is normally inserted, the second switch is turned on after the third switch is turned off. When the mini disc is incorrectly inserted in the horizontal direction, the second switch is turned on before the third switch is turned off. Can be detected.

As described above, when the mini disc MD is incorrectly inserted into the tray 11, the loading motor 17 is rotated in the unloading direction, and the misinserted disc is pulled out again by the misinserted mini disc. You can prevent the deck from being damaged.

As described above, according to the present invention, since the pinch roller moves up and down with the tray part, the mini disc is moved between the tray part and the disc storage part or the disc reproducing part, thereby reducing the overall number of parts and reducing the load of the tray part. It is easy to move up and down.
