The worm gear 46 on the rotating shaft 42 constituting the cartridge operating member 40 is engaged with the shaft gear 44 on the cartridge transfer motor 40 as it is driven while being rotated at the same angle as the opening angle of the 28. Rotation shaft 42 and the feed pinion 48 engaged with the rack gear 34 on the body portion 60 of the disc cartridge 36 is rotated in a predetermined direction, as a result of the entire disc cartridge 36 is a door ( Upward in conjunction with the opening operation of 28) It is moved into a straight line.

The rotating shaft 42 constituting the cartridge operating member 50 during the door opening operation and the ascending operation of the disc cartridge 36 interlocked therewith is a front and rear through hole on the case 72 constituting the rotating shaft clamping member 52. While inclined in the height range of the through hole 70 by the rotational movement of the cartridge lifting motor 40 and the elastic action of the spring 74 installed in the upper and lower portions of the case 72 in the state fitted to the (70) The worm gear 46 at the inner end of the rotary shaft 42 and the feed pinion 48 at the outer end are respectively disposed on the shaft gear 44 on the cartridge lifting motor 40 and on the body 60 of the disc cartridge 36. It is rotated in a state where it is always orthogonally coupled to the gear 34.

In this way, when the door 28 is opened and the disc cartridge 36 is raised, the user presses the door closing switch after replacing the disc 16 in the disc storage groove 58 on the disc cartridge 36. As the forward / reverse drive motor 30a constituting the drive means 30 is rotated in the reverse direction, the rotation rack gear 32 is circularly moved downward to close the door 28, and the cartridge lift motor 40 is reversed. The cartridge operating member 50 is operated in the reverse direction while being driven so that the disc cartridge 36 slides downward from the inner side of the door 28, and the door 28 is completely closed so that the rotary rack gear 32 is placed on the limit. Upon contact with the switch 78 again, the drive of the forward / reverse drive motor 30a and the cartridge lift motor 40 'is stopped under the control of the microcomputer receiving the signal, and the rotary shaft 42 constituting the cartridge operating member 50 is stopped. ) Is returned to the horizontal state.

The lifting operation of the disc cartridge 36 during the opening and closing operation of the door 28 is a cylinder formed on the outer surface of the body 60 of the coupling piece 56 and the disc cartridge 36 formed on the inner surface of the door 28. It is made by the interaction of the guide ribs 62 of the form, and when the disc 16 accommodated in the disc cartridge 36 is seated on the turntable 22 by the closing action of the door 28, the clamper holder ( The clamper 64 fitted into the 66 presses the disk 16.

In this state, when the user designates a track number to be played back and presses the play switch, the disk 16 is rotated by the operation of the spindle assembly 24 and the optical pickup device 26 is driven to operate on the disk 16. The reproduction operation of the information recorded on the recording surface is performed.

When the present invention is applied, the disk cartridge is lifted in conjunction with the opening / closing operation of the door, and thus the loading and unloading operation of the disk is automatically performed, thereby increasing the space utilization, and the image of the product by the unique operation. There is an effect that you can increase.
