PURPOSE:To reproduce an automatic play, etc. on both sides of a disk by means of a common cartridge by attaining the shift of the cartridge along both sides of a record disk, etc. CONSTITUTION:With operation of a play button 83, a processing circuit 84 drives at first a motor 8 to turn a turntable 2 and a record disk 1. When a solenoid 61 is energized after the disk 1 reaches its steady speed, a reproduction stylus 6 touches the disk 1 to start the play. A mobile member 20 is moved to the inside of the radius direction of the disk 1 along the sound groove of the disk 1. When the stylus 6 reaches the most inside groove in the radius direction of the disk 1 to complete the play, the solenoid 61 is degaussed. At the same time the motor 8 is de-energized. Thus it is possible to reproduce an automatic play, etc. on both sides of a disk by means of a common cartridge. |
