Abstract

PURPOSE:To avoid the drop-out due to dust and finger print or the like, by preventing the dust invasion from the rotary holes, through the constitution providing ribs around the external circumference of the rotary holes of the upper and lower plates of the cassette case. CONSTITUTION:The cassette case 10 consists of the upper plate 11 and the lower plate 12, the space 13 containing the disc 1 is formed between them, the upper and lower plates 11 and 12 are provided with the ribs 14 and 15 supporting the disc 1 at non-reproduction to avoid the dust invasion from the rotary hole 16 to the space 13. At the external of the rotary hole 16, the iron plate 17 which pulls the upper and lower plates 11 and 12 down and upper and detaches the rib 15 from the disc 1 at non-reproduction, is implanted. In reproduction, the electromagnet 41 placed up and down the cassette case 10 is energized to pull the iron plate 17 and the disc 1 is turned with the rib detached from the disc 1 slightly.
