A detection holeis provided in a tray, on which a cartridge type recording medium is mounted and housed, at a position corresponding to an information hole of a cartridge, a detection leveris provided on a back surface of the trayon the lower surface side of the detection hole, and a switch sectionis provided on a frameon the lower surface side of the detection leverwhile the trayis housed within the frame. Accordingly, the switch sectioncan be separated from the motion of a base since the switch sectionis fixed to the frame, and consequently, the structure can be simplified and the space efficiency can be enhanced.

Recording medium driver and recorder/reproducer

A stopperis provided which detects a projected part formed on an upper cartridge case of a shield type cartridge so as to prevent the shield type cartridge from being inserted. Accordingly, mechanical lock caused by the insertion of the shield type cartridge can be prevented.

Recording medium drive device

The traywhich can mount both of a cartridge type recording medium and a bare-disc type recording medium, includes a placing surfacehaving a detection holefor detecting information of the recording medium; a rising portionformed so as to rise from the placing surfaceat a front side end. The rising portionhas a disc holderrotatably provided for positioning the bare-disc type recording medium. Hence, the disc holdercan be moved to an accommodation position A for being displaced not to cover the detection holein the placing surfaceAccordingly, an area on the placing surfacein which detection portions such as the detection holeare formed becomes wider, so that the detection portions such as the detection holecan be sufficiently formed as well as a space for providing the detection portions corresponding to a cartridge containing a variety of information can be sufficiently obtained.

Recording medium drive

A reproducing/recording apparatus including a first disk tray () for mounting a first disk thereon and a second disk tray () for mounting a second disk that is of a type different from the type of the firs disk thereon. The first disk tray () is adapted to be moved into and away from the apparatus through a single disk inlet/outlet port (A) with the second disk tray () laid thereon. The reproducing/recording apparatus can be downsized even when it is adapted to reproduce information from and record information onto a number of disks of different types.

Reproducing/recording apparatus

A reproducing/recording apparatus includes a first reproducing/recording mechanism () for reproducing data from and/or recording data onto a cartridge/disk combination (first disk) () or a bare disk (second disk) (), the disk main body (A) being contained in the cartridge (B). The first reproducing/recording mechanism () has a traversing mechanism () disposed oppositely relative to the recording area of the first disk () or the second disk (), a clamping mechanism () disposed oppositely relative to the traversing mechanism () with the first disk () or the second disk () interposed between them in order to clamp the first disk () and a keep member () adapted to bias the first disk () toward the side of the first disk tray at the time of clamping the first disk () by the clamping mechanism (). The disk made to show a right attitude because the disk is pressed by the keep member () even when the first disk () is pushed up at an edge thereof by the sensor section arranged at the traversing mechanism ().

A disc changer comprises a receiving unit for receiving a plurality of discs, a base unit, a playback unit and a transfer unit for transferring one of the plurality of discs to the playback unit. The transfer unit is movable in the perpendicular direction to the base unit. The playback unit has on its opposite ends swing support axes. The playback unit is swingable around the swing support axes relative to the base unit and the transfer unit, respectively. The playback unit has a gear. The base unit has a base unit-gear segment portion and the transfer unit has a transfer unit-gear segment portion. The gear is held between the base unit-gear segment portion and the transfer unit-gear segment portion so as to engage with these gear segment portions.

Disc changer

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 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.

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 plurality of disc players are arranged in a vertical direction, a plurality of frames each holding a tray are mounted in a magazine pack. A magazine pack loading means is provided for moving the magazine pack taken into an apparatus body, and a frame separation and holding means is provided for separating the frames one at a time and positions them at predetermined locations corresponding to the disc players when moving the magazine pack by the magazine pack loading means. A tray transfer means is provided for transferring the trays between the predetermined locations and the disc players.
