Referring to the operation and effects of the present invention configured as described above are as follows.

First, when the optical disk is seated on the tray 28 to be stored in the storage end 21 or the optical disk stored in the storage end 21 is pulled out, the tray driving motor is driven in the tray opening direction so that the gear ( As the 30 rotates, the tray 28 is pulled out while being engaged with the rack 31 formed in the gear 30 and the tray 28.

When the tray 28 drawn out as described above is inserted, the tray driving motor is driven in the tray cross direction so that the gear 30 and the rack 31 are engaged to close the tray 28.

When the optical disk is mounted on the tray 28 to reproduce the optical disk, the optical disk is brought into close contact with the tentable 32 by driving the clamper driving motor in the clamper upward direction to raise the clamper 34.

In this case, the rotational force of the clamper driving motor is transmitted to the rack of the second D-CUT gear 36 and the second staircase plate 39, and is mounted to the clamper lever 35 by the second stair groove 38. As the second driving pin 37 is raised, the clamper 34 integrated with the clamper lever 35 is also raised.

The optical disk of the storage end 21 is fixed so that the optical disk stored in the storage end 21 does not flow up and down.

In addition, in order to reproduce an optical disc of a desired storage end or to store and store an optical disk in a desired storage end, the storage end 21 should be vertically moved so that the height of the desired storage end and the height of the tray 28 coincide with each other. The storage end drive motor 23 is driven.

The loading lever rotates and the optical disc seated on the tray 28 is upward. And interposed between the lower rubber rollers 44 and 43, and the upper and lower rubber rollers 44 and 43 transfer the optical disk to the storage end 21.

However, when the loading motor 40 rotates in the unloading direction and the lower gear 45 rotates in the unloading direction, the unloading plate 42 is horizontally moved by the second vandal cam 48 to unload the lever. The optical disc stored in the storage end 21 is interposed between the upper and lower rubber rollers 44 and 43 by rotating.

Of course, the rotational force of the lower gear 45 is transmitted to the lower rubber roller 43 so that the optical disk interposed between the upper and lower rubber rollers 44 and 43 is transferred from the storage end 21 to the tray 28. .

As described above, while the lower gear 45 rotates in the unloading direction, the inclined surface of the upper directional protrusion 45a formed on the lower gear 45 and the inclined surface of the lower directional protrusion 47a formed on the upper gear 47 are The rotational force of the lower gear 45 is not transmitted to the upper gear 47 because they rotate while facing each other.
