摘要： PROBLEM TO BE SOLVED: To provide an optical disk device capable of obtaining uniform and sufficient optical disk holding force.
SOLUTION: At the time of holding an optical disk 12 and reproducing recorded information, the recording surface 12a of the optical disk 12 is mounted on the mounting part 32 of a clamp mechanism 30, a projection part 33 is passed through to a label side 12b through the hollow part 12c of the optical disk 12, a chuck pawl 35 is taken out from the projection part 33 and the optical disk 12 is held. At the time, the chuck pawl 35 is turned around a spindle 34 along the tangential direction of the projection part 33, and the base end part 35a of the chuck pawl 35 is pressurized and turned by an elastic pressurizing part 36a provided on a pressurizing member 36. Thus, in the case that a specified chuck pawl 35 is hooked, since the movement of the pressurizing member 36 is made possible by the elastic deformation of the pressurizing part 36a which pressurizes the hooked chuck pawl 35, the other pressurizing parts 36a pressurize the base end parts 35a of the other chuck pawls 35. Thus, the other chuck pawls 35 surely hold the optical disk 12.

摘要： PROBLEM TO BE SOLVED: To provide an optical disk apparatus in which reduction of a cost and miniaturization of an apparatus can be performed by lightening and simplifying mechanism by reducing the number of parts.
SOLUTION: When information recorded in an optical disk 12 housed in the inside of a main body 13 is read by an optical head part 20 and first and second traverse gears 42A, 42B are rotated by a drive gear 41, the optical head part 20 is moved in a radial direction of the optical disk 12 along a supporting member 30 by a connection arm 43 connecting the second traverse gear 42B and the optical head part 20. Also, the supporting member 30 is rotated to a reproduction position and a standby position for the optical disk 12 by the first traverse gear 42A and the second traverse gear 42B moving the optical head part 20. Thereby, since rotation of the supporting member 30 and movement of the optical head 20 can be performed by simple mechanism, movement mechanism can be simplified, while the number of parts can be reduced and weight can be reduced, cost reduction and miniaturization of the apparatus can be performed.

摘要： PROBLEM TO BE SOLVED: To provide a disk unit which can prevent a deterioration in the attenuation function of a silicon oil damper by a shift of a member to be isolated from vibration to a support member by its weight when the support member is sidelingly installed without increasing parts count. SOLUTION: The vibration isolated member 3 is supported elastically by a support member 4 with a compression coil spring 5 and a silicon oil damper 6. A folded back section 5d which is made to go to the vibration isolated member 3 is formed by folding back one end of the coil spring 5 by the side of the support member 4, and its tip side is made to penetrate an engagement hole 3a prepared on the vibration isolated member 3. If the vibration isolated member 3 is going to shift toward the surface direction with the support member 4, the engagement hole 3a abuts the folded back section 5d and slippage is regulated.
