PURPOSE:To miniaturize a disk device and, at the same time, to simplify the constitution of the device, by providing a buffer member which is firmly fitted to part of the inner wall of a cassette case, forcing member pushing a disk in the pressure-contacting direction, and disk rotation driving turntable which separates the disk contained in the loaded cassette case from the buffer member against the pushing force. CONSTITUTION:A ring-like buffer member 6 made of felt, etc. is firmly sticked to part of the inner wall of a cassette case facing to the lower surface of a disk 4. A plate spring 7 pushes down a disk pressing member 5 through a ball 8 and, by the pushing down force, the lower surface of the disk which is the recording and reproducing surface of the disk 4 is pressure-contacted with the buffer member 6. Moreover, the outer periphery of a flange member 13 forming a conical guide peripheral surface 13a is contacted with the inner surface of a turntable 12 and the flange member 13 is pushed upward by the elasticity of an expanding type spring 14. The upward movement of the flange member 13 is prevented by an E-ring 10 when the cassette case 1 is not loaded. |
