Abstract:
PURPOSE:To unload a disk in a simple and quick way, by providing a cover body on the side edge surface of a case main body in a free opening/closing way with turning, and forming a supporting guide groove at the inner circumference of the case main body which supports the outer circumference edge of a disk- shaped recording medium. CONSTITUTION:An opening part 4a formed to the side edge surface of the main body 4 of a thin case is covered with a cover body 5 which is connected rotatably to the case main body 4 via a plastic hinge 6. When a disk 3 is sotred into the case 4, the outer circumference edge of the disk 3 has a contact with a supporting guide groove 8 of the case 4. At the same time, the outer circumference edge surface of the disk 3 is fixed by an elastic holder bar 7 attached to the cover 5. Then the disk 3 rolls out of the case 4 by the inclination of the groove 8 provided inside the case 4 and as soon as the cover 5 is opened. Therefore the disk 3 can be taken out of its protecting case on a disk shelf in a simple and quick way.
