A disk apparatus includes a supporting mechanism inwardly projecting from an inner surface of a wall of a housing, the wall having a disk insertion/ejection opening, a disk conveying mechanism that is supported by the supporting mechanism so that the disk conveying mechanism can be moved along a disk conveyance path, via which a disk is conveyed, toward a predetermined position within the housing, an engagement groove formed in the supporting mechanism and having a straight portion parallel to the disk conveyance path and a locking portion perpendicular to the straight portion, a locking member that is rotatably disposed on the disk conveying mechanism and that is engaged with the engagement groove so that the locking member is pressed toward the locking portion of the engagement groove, and an actuation mechanism for rotating the locking member to release locking of the locking member when playing back the disk.

Disk conveyance apparatus and support means for supporting conveyance apparatus

A disk apparatus includes a guide mechanism for guiding conveyance of a disk so that the disk can be advanced or retracted in a direction of conveyance of the disk, rotary members rotatably disposed on both ends of the guide mechanism, a disk conveying mechanism disposed opposite to the guide mechanism between the rotary members, and a rotating mechanism for, when retracting the guide mechanism toward a disk insertion/ejection opening, rotating the rotary member so as to move the disk conveying mechanism in a direction which intersects with the direction of conveyance of the disk.

Disk conveying means for a disc drive using retractable rollers and guide plates

A disk device including a first disk holder movable with disk conveyance, a second disk holder opposed to a groove portion formed in the first disk holder and holding a disk grippingly in cooperation with the first disk holder when the first disk holder holds the disk, and a supporter which supports the first disk holder and which causes a support position for the first disk holder to be shifted in accordance with the movement of the first disk holder to be shifted in accordance with movement of the first disk holder, realizes reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost.

Disk device

A snap fit mechanism has an elastic tongue provided on a base of the mechanism. On the tip of the tongue is provided an engaging claw that has an engaging inclined face. A far end of the engaging inclined face from the base is arranged so as to be located between the outside face of the elastic tongue and the centerline C in a longitudinal direction of the elastic tongue. Further, on the tip of the elastic tongue is provided an engagement-maintaining inclined face which gives an outward load to the elastic tongue on receiving an accidental load thereon so as to reduce the inward elastic deformation of the elastic tongue, thereby preventing the accidental release of the engagement of the tongue.

Snap fit mechanism

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 capable of storing a plurality of disks therein includes a disk holder capable of changing its vertical position to hold a disk, a driver to drive the disk holder, and the disk holder performs a rotational movement and the changing of its vertical height by means of the same driving mechanism of the driver. The disk device realizes a reduction in size and number of parts, prevention of damage to disks, a shortened operation time for a plurality of operations, improved vibration resistance, and a reduced manufacturing cost.

A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost is provided. The disk device capable of storing a plurality of disks includes an operation setting means to actuate the disk holding means according to an operation mode of the disk, and an operation mode switching means to switch the operation mode of the operation setting means based on contents of disk operation.

Disk device holding a plurality of disks at its inner diameter

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.

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 realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality operations, improved vibration resistance and less expensive manufacturing cost is provided. The disk device capable of storing a plurality of disks loosely fitted and supported at its inner diameter, including separable loose mandrel mechanisms, when the mandrel mechanism is loosely fitted to the disk, the disk holder holds the disk, and one end of the a second mandrel mechanism is connected to another end of a first mandrel mechanism in a state that the disk is raised to a height abutting upon a support of a ceiling side formed on the first mandrel mechanism.

A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost is provided. In the disk device when a disk is reproduced, a disk reproducing mechanism is moved to become a center of disk coincident with a center of turntable thereof, a first disk holding mechanism is moved downward to load the disk on the disk reproducing mechanism, then a disk clamping mechanism is moved to clamp the disk loaded on the disk reproducing mechanism, and the disk is reproduced after the first and second disk holding mechanism release the disk and are taken away from the disk.

A supplementary roller is disposed on the end of a disk guiding section so that the outer face of the cylindrical shaped section of the supplementary roller is placed on the conveying roller side by the protruding section formed on disk guiding section
