PURPOSE:To prevent noise of a record disc, by eliminating dusts on the disc, through the provision of a nozzle which jets air or sucks air toward the record disc at the front position of a record stylus in the direction of record disc rotation. CONSTITUTION:When an air pump is operated during the reproduction of a record disc, air is jetted from a nozzle or sucked via a pipe 13, a rotary joint 12, a pipe 11 and a nozzle shafr 7. Since the nozzle 4 is mounted on the front position toward the direction of rotation of the record disc from a record stylus 2, dusts on the record disc or in the record grooves are blown out or sucked with the air from the nozzle 4 ahead the running of the stylus 2, allowing to avoid the dusts from being attached to the stylus 2. Thus, production of noise can be prevented. |
