A disk accommodating unit accommodates a plurality of disk trays for holding a disk. A disk processing unit reproduces data from or records data to a loaded disk. A loading mechanism loads a selected disk together with the disk tray from the disk accommodating unit to a position of the disk processing unit. The loading mechanism includes a tray drawing pinion provided in the disk processing unit; a disk tray that includes a tray rack engaged with the tray drawing pinion; and a rack plate that includes a tray drawing rack engaged with the tray drawing pinion, and draws a tray in at a first half process of the loading and stops the tray at a second half process of the loading.

Disk changer

On the inner surface of a guide rail () having a concave groove, which extends in the vertical direction along a motion path of a disc drive () moved by a mover unit (), a biasing cam () having thickened swelling parts () at both ends is so provided as to have the groove width narrowed at both the upper and lower ends. A plate spring () which is pressed into contact with a guide surface of the surface of the biasing cam () by elastic biasing force is attached integrally to the disc drive (). At the home position where the disc drive () operates and at the position where the disc drive () is lifted up, the plate spring () is strongly pressed into contact by the swelling parts (), and the disc drive () can be prevented from being moved by impact or the like from outside during operation. While moving, the pressing force is weakened so that load applied by the mover unit () can be reduced.

Movement adjusting device, method thereof, and carrier device

A motor is provided on a slide base of a disc player. A flexible cable for supplying an electric power and control signals to the motor and a player and the like is connected to the motor at one end thereof, and to a player disposed in a chassis at the other end. When the slide base is located in a disc storing position, the flexible cable is bent ahead of the both ends, so that the wiring within the disc player can be simplified.

Disc player

A linear rack gear is formed on the underside of a slide base, and a planetary gear provided in a chassis, which rotates in engagement with this linear rack gear, causes the slide base to move back and forth. When the slide base is located in its disc store position, the planetary gear engages with a first arcuate rack gear formed in the chassis continuously with the linear rack gear and revolves in accordance therewith, whereupon a clamp causes a clamp cam to slide in a lateral direction to move a float base up and down, thereby achieving clamp and release of a disc, so that the disc player can be manufactured at low cost due to a reduced number of parts in excellent production efficiency.

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

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 positioning system is provided for use in an information recording/reproducing apparatus for positioning a cartridge containing an information recording medium on a chassis mounting information recording and reproducing structure. Such positioning system comprises positioning holes formed on the cartridge containing an information recording medium; and positioning pins formed on the chassis mounting information recording and reading structure. In particular, when a cartridge containing an information recording medium is inserted into the recording/reproducing apparatus, one of the positioning pins is caused to insert into a corresponding positioning hole earlier than the insertion of other pin(s) into other corresponding positioning hole(s).

Positioning system for use in an information recording/reproducing apparatus

A disc player has a cartridge holder formed with an opening for loading a disc cartridge containing an optical disc through the opening. The disc cartridge has a slidingly opening shutter to expose an information recording surface of the optical disc contained in the cartridge, so as to permit information recording or reproducing. The disc player includes a disc cartridge loading system for transporting the disc cartridge in the same direction that the shutter moves on the disc cartridge. The disc player also includes a guide plate provided on the inner side of the opening within the disc player for guiding the disc cartridge when the disc cartridge is being transported into or out from the disc player through the opening. In particular, the guide plate has an inclined edge portion formed into a slope gradually inclined in an insertion and removal direction of the disc cartridge.

Disc player with guide plate

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 is comprised of 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 comprised of an engaging element and an engaged element which is separated from the engaging element when the information recording mechanism is not driven.

A cartridge of write and read type or a cartridge of read only type is selectively loaded to a recording and reproducing apparatus. The recording and reproducing apparatus is provided with: a magnetic head for applying a magnetic field; a head movement device for moving the magnetic head between a near position and a far position; a switching lever, which is movable between a non-regulating position to allow the magnetic head to move between the near position and the far position, and a regulating position to regulate the position of the magnetic head at the far position; and a slide plate disposed movably on a cartridge holder and having a protruded portion which is opposed to the cartridge stored in the cartridge holder. The protruded portion abuts to the loaded cartridge to move the slide plate, and the switching lever is positioned at the non-regulating position by abutting to the moved slide plate if the loaded cartridge is the write and read type. The protruded portion is engaged with a judgement recess of the cartridge, and the switching lever is positioned at the regulating position if the loaded cartridge is the read only type.
