A rack and pinion gear mechanism includes a rack forming member having a rack; a pinion gear which engages releasably with the rack of rack forming member; and an elastic member which contacts with one portion of the rack forming member and deformed by an elastic deformation corresponding to a displacement of the rack forming member by a confliction of tooth points, the one portion is located opposite side to a tooth of the rack that contacts firstly with a tooth of the pinion gear and the gear mechanism further includes a positioning means to fix the elastic member in a cantilever manner to define a positioning of a free end of the elastic member in height.

Rack-and-pinion gear mechanism

A disk device for reproducing information includes a clamper that is used to clamp exchangeable disks. The disk device has a movement regulating member which is engaged with a sliding hole made on a base. A clamper base is engaged with a cam hole made on the movement regulating member to swing around a swinging axis on the base as a center. A clamper arm is supported on the clamper base to hold the clamper which clamps the disk. A positioning member is arranged on the base to abut with the clamper base when the clamper base swings. An energizing member urges the movement regulating member along a direction substantially perpendicular to the sliding direction of the movement regulating member.

Disk device

A disk device including a movable portion which supports pivotally and enably to swing a feed screw axis, a thread motor to drive a small gear and the like which engage with a gear interlocked in an end portion of the feed screw axis thereby to rotate the feed screw axis, and a control screw to perform a height control of the movable portion.

Disc drive

A disk device in which a precut portion of sub cam plate and a protruding portion of locking plate are made in a slanted shape and at the same time the sub cam plate is rotated by a pressure when the protruding portion is inserted into the precut portion.

By a disk device including: a reproducing base which is supported pivotally and enably to swing on a base, and on which a turntable is set; a supporting member which is supported pivotally and enably to swing on the base and which supports the reproducing base in a predetermined position; a clamper which is supported pivotally and enably to swing on the base and which opposes to the turntable to pinch and hold a disk; and a movement regulating member which regulates swing movements of the supporting member and the clamper, supporting by the supporting member in relation to the reproducing base is made sure to prevent deformation of the reproducing base by a clamping force of the clamper.

Disc device

A disk device includes a disk playing section provided with a pickup reading recorded information on a disk and a rotatable turntable mounting a disk, a damper section supporting said disk playing section to float and a rotatable base section which disposes said disk playing section through said damper section and which forms an engaged section by an engaging action and an engaging section which engages with an engaged section. The invention is further characterized in that when said base section is rotated to a disk playing position, said engaged section is adapted to engage with said engaging section.

Disk device with rotatable playing section

A disk device includes a rotatable bar-shaped fixing element which is fixed loosely to an inner peripheral hole of each of a plurality of disks and a support element which forms a support section. The support section supports a section of a disk on a peripheral section of the fixing element. The support element is displaced in a direction of a rotational axis of the fixing element based on the rotations of the fixing element.
