A disk devicecomprising a disk cartridgeand a diskaccommodated therein. The disk cartridgeincludes a body case: opened with a window for exposing a recording surfaceof the disk; and provided with a shutterto be moved in a manner capable of opening/closing the window. The body caseis provided with: a rotating bodyin a gear shape having an outer peripheral surface exposed to the exterior of the body case; and transmissionfor transmitting the rotation of the rotating bodyto the shutter. Provided in a disk driving apparatus for recording a piece of information into or reproducing the information from the diskare: a guiding rib; and an operation rack along the disk inserting direction. Provided on an outer surface of the body caseis an operational-position determining groove.in a recessed groove shape along the inserting direction of the disk deviceand near the rotating body, and the rotating bodyis engaged with the operation rack while engaging the groovewith the guiding rib so as to conduct the positioning, to thereby open/close the shutter

Upon insertion of the disk deviceinto the disk driving apparatus, the guiding rib causes rotation regulatorto rotate so that the rotation regulatoris disengaged from the rotating bodyand the operation rack engages with the rotating bodyto thereby rotate the rotating body, thereby opening/closing the shutter bodyvia shutter opening/closing mechanism

Disk cartridge, disk device and shutter opening/closing mechanism including a rotating body

A disk player has a disk cartridge for being loaded thereon, and accommodating a disk-type recording medium. The disk cartridge has a shutter arranged thereon, for performing slide-opening/closing in order to expose an information surface of the disk-type recording medium. The disk player includes a carrier mechanism for carrying the disk cartridge to an information regenerating location and an information recording location, and a shutter sliding mechanism for slide-opening/closing the shutter. The shutter assumes an intermediate position of sliding when the disk cartridge is located at one of the information regenerating location and. the information recording location, and assumes a terminal position of sliding when the shutter is located at the other one of the locations. The disk player also includes a driving mechanism including an engaging element and an engaged element which is separated from the engaging element when the information recording mechanism is not driven.

Disk player

An apparatus for transferring a movable body comprises a rack having flexibility, a pinion for driving the rack and a guide device for guiding the rack. The guide device has a curved portion. The pinion may locate along the curved portion of the guide device. The movable body comprises a disc.

Apparatus for transferring a movable body

A disk player has a structure capable of mounting on a turntable a disc-shaped recording medium contained within a cartridge. Such disc player comprises a cartridge transporting system capable of transporting the cartridge in a direction generally parallel to a sliding direction of a shutter of the cartridge; and a pivotable chassis on which the turntable is mounted, said chassis being pivotable by a chassis driving system so as to enable said disc-shaped recording medium to be mounted on the turntable, with its pivoting axis being generally parallel to a transporting direction for transporting the cartridge.

Disc player having an improved disc cartridge loading system

A case,for containing a disk type recording medium,provided with a center bore,, a clamped part,and a recording part,comprises a cartridge,and a protective case,which is detachably mounted on the cartridge. The cartridge,consists of a lid body,including a center opening,and a first annular projection,formed around the center opening,, and a cartridge body,including a center opening,and an opening,. The clamped part,of the disk type recording medium,is adapted to be exposed through the center openings,and,. The protective case,includes a plate part,, a second annular projection,and an engaging portion,. The second annular projection,enters into the center opening,. The disk type recording medium,is positioned between the annular projections,and,with the engaging portion,engaged with the center bore

Case for containing disk type recording medium

A disk player comprises a turntable for rotatably holding an optical disc; an optical pickup for recording information into and reading information from the optical disc, an elongated guide shaft arranged in a predetermined moving direction of the optical pickup for guiding the optical pickup to move in said predetermined direction, a pivotable chassis for mounting the turntable, the optical pickup and the elongated guide shaft, a cartridge holder for receiving and holding a cartridge containing the optical disc. In particular, an adjustment mechanism is provided on the pivotable chassis for adjusting a positional relationship between the optical pickup and the turntable by moving one end of t he elongated guide shaft in a plane which is generally parallel with a recording surface of the optical disc.
