PURPOSE:To make dusts come out of the sound groove of a record disc, without hurting the groove, so that the disc may be washed completely by applying ultrasonic waves to the record disc which is immersed in a washing liquid. CONSTITUTION:A record disc 2 is placed on a record disc member 8 and is held between the member 8 and a record disc pressure member 10. Then, a push member 21 is pushed so that the disc 2 is immersed into the washing liquid 1 in a washing liquid bath 3. An ultrasonic wave oscillating portion 6 attached to the outside of a bottom wall 5 is operated to apply ultrasonic waves to the disc 2. After the washing, the push member 21 is pushed again to release the locked condition so that the disc 2 is pulled up from the liquid 1. After that, a record disc holding member screwed on a column 9 is removed so that the disc 2 is taken out.On the other hand, a supporting portion 30 is arranged at one side of a record disc holder so that a record stylus cartridge 29 is washed together with the disc 2. |
