PURPOSE:To facilitate the replacement of cleaners and also to realize a disk cleaning job even at the time of reproduction by securing such a constitution where a cleaning member can be taken out of a front operating part and the cleaning job is carried out independently of the shift of a reproduction stylus. CONSTITUTION:A rotary arm 50 can move reciprocatively between the outermost circumference and the innermost circumference of a disk 24 and also turn from the innermost circumference up to the waiting position of a cleaning means while holding this cleaning means. A cleaner revolving means includes a cartridge holder 51, a cam gear 55, a base 57, a pinion gear 59, etc. A drive rack 27 shifts linearly the cleaning means up to the outside of this cleaning device. A cleaner shift means includes a rail 28, a drive gear 29, a worm 32, a cartridge guide, etc., in addition to the rack 27. A drive means contains a motor 31 which drives a cleaner revolving means and shifts the cleaner shift means. In such a constitution, the cleaner can be easily replaced at a front operating part and also a cleaning job is carried out even at the time of reproduction.
