A gear shift adjusting mechanism includes: an adjustment unit including a first slider; an adjustment target module including a second slider; and a switch unit including a first rotation shaft and a link member supported rotatably with respect to a fixing member about the first rotation shaft. The link member includes a first engaged part that is engaged with a first engaging part of the first slider and a second engaged part that is engaged with a second engaging part of the second slider. The switch unit moves at least one of the first rotation shaft, the first engaging part, or the second engaging part so that at least one of a first distance between the first rotation shaft and the first engaging part or a second distance between the first rotation shaft and the second engaging part is changed.

Gear shift adjusting mechanism and headlight device

A rotation adjustment mechanism includes a rotation target module supported to be freely rotatable with respect to a fixation member around a first rotary shaft and an adjustment unit including a slider. Rotation of the rotation target module around the first rotary shaft is regulated by a contact point where a connection groove of the rotation target module and a projection part of the slider contact each other, and a shape of a surface of the connection groove contacting the projection part is a shape formed by a locus that successively connects the contact points of the connection groove and the projection part each of which is obtained each time the rotation target module is moved around the first rotary shaft by a unit angle and simultaneously the projection part fixed to the slider is translated by a constant amount in a direction parallel to the slide axis.

Rotation adjustment mechanism and headlight device

A rotation adjustment mechanism includes a rotation target module supported by a fixation member to be freely rotatable around a first rotary shaft and an adjustment unit supported by the fixation member and including a slider movable along a slide axis pointing in a direction orthogonal to the first rotary shaft. The adjustment unit is supported to be freely rotatable around a second rotary shaft parallel to the first rotary shaft and provided on the fixation member. The rotation target module includes a connection groove. The fixation member includes a cam member. The cam member has a guide surface in an arc-like shape that maintains constant a rotation angle of a contact point where the connection groove and a projection part of the slider contact each other around the first rotary shaft with respect to a unit movement amount of the slider in a direction parallel to the slide axis.

An adjustment holding portion () for adjusting the inclination of a guide shaft () guiding an optical pickup () in a radial direction with respect to a base () is mounted to the base () at a first supporting point (), a second supporting point () and a third supporting point (). When the optical pickup () is located at a first position on the inner circumference side of the optical disk, the shaft-receiving portion () of the optical pickup () is located on a line connecting the first supporting point and the second supporting point. When the optical pickup () is located at a second position on the outer circumference side of the optical disk, the shaft-receiving portion () of the optical pickup () is located on a line connecting the first supporting point and the third supporting point.

Optical disk device and adjusting method thereof

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

Of an integrated type leaf spring, a first abutting portion of first leaf spring portion of a narrow spring piece abuts against the bottom surface of a disk motor base to apply reactive force of the first leaf spring portion to the disk motor base. At the same time, a second abutting portion of a second leaf spring portion abuts against the top surface of a mechanical chassis base to apply reactive force of the second leaf spring portion to the mechanical chassis base. Reactive force of the narrow spring piece becomes the sum of the reactive force of the first leaf spring portion and the reactive force of the second leaf spring portion.

Inclined angle adjusting mechanism and inclined angle adjusting method

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

An MD is feed to a fixed position in a device by a case-stored recording medium disk loading mechanism having a slit mechanism , an MD holder feeding arm and the like. The disk is loaded onto a turntable . A drive plate is provided which is driven in a coupled manner and refuges a non case-stored recording medium disk loading mechanism, which has a CD clamp and a CD adapter , to a position which does not interfere with the loading of the MD onto the turntable

A disk device is includes first support shaft which supports a retaining arm, retaining a second turntable, to reciprocate vertically and a second support arm which supports the retaining arm to rotate and refuge horizontally so that the second turntable which supports a second disk which is not stored in a cartridge and which transmits a rotational force to a second disk can be loaded and separated from a first turntable which supports a first disk and which transmits a rotational force to a first disk.
