Title:
DISC CASE
Document Type and Number:
Japanese Patent JPS6069872
Kind Code:
A
Abstract:
PURPOSE:To attain a disc case which prevents a damage due to oscillation and can make a device body small-sized, by providing an elastic member in a position of a disc, which faces a driving aperture part, so that the disc is de-energized to the side of the disc driving aperture part. CONSTITUTION:While the disc case is carried, a disc 1 is pressed to a lower shell 5 of the disc case by a flat spring 2, and the disc 1 is prevented from being moved freely in the case. The disc is placed on a disc motor as shown in figure. A disc motor 9 which rotates and drives the disc 1 is inserted from a driving aperture part 6 of the lower shell 5 of the disc case, and the disc 1 and the lower shell 5 of the disc case are not brought into contact with each other, and the disc 1 is rotatable in the disc case. The flat spring 2 is deformed more than carrying of the disc case to press the disc 1 to the disc motor 9. Since a spring receiver 3 is brought into contact approximately with the flat spring 2 by a point, the rotation load of the disc 1 is very low.
