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 disk player is provided which is capable of being automatically loaded with and playing one of a plurality of types of disks when the disk is inserted in the disk player. A driver moves the receiving module from an opened position to a closed position in response to either the detection signal from disk detector or the command signal from a switch.

Auto-loading disk player

An annular disc holder has a plurality of partition plates for holding a plurality of discs in an upright position, and a reproducing device is provided for reproducing a desired disc. A carrying device is provided for carrying the desired disc between the disc holder and the reproducing device. The partition plates are radially arranged. The carrying means is provided for returning the desired disc to the disc holder from a large width portion between the partition plates.

System for carrying and reproducing a disc

A disc holder is annularly provided for holding a plurality of discs, and a reproducing device is provided in a central portion of the disc holder for reproducing a desired disc. A carrying device is provided for carrying the desired disc between the disc holder and the reproducing device. The carrying device has a groove for slidably engaging with a peripheral portion of the desired disc, and a pair of inclined surfaces for separating adjacent discs on both sides of the desired disc from the desired disc.

System for reproducing a recorded disc

An annular disc holder is provided for holding a plurality of discs. The disc holder is rotatably mounted on a base and is guided by a guiding device provided between the disc holder and the base so as to be rotated about an axis.

System for reproducing a disc

An automatic disc changer having a disc player, a disc holder for storing a plurality of discs, and a disc loading device for carrying a disc from the disc holder and for loading the disc on the disc player, wherein the disc loading device has a first arm pivotably mounted on a shaft which is slidably mounted on a base in a direction perpendicular to an axis of a disc to be carried by the disc loading device, a second arm pivotably mounted on the base, means for moving the shaft in a direction so that the first arm is rotated to engage a disc in the disc holder and move the disc outwardly from the disc holder; and means for rotating the arm toward the disc held by the first arm so as to engage the disc, whereby the disc is grasped by the first and second arms.

Automatic disc changer for a disc reproducing device

A disc holder has a support portion comprising arcuated portions. The arcuated portions include opposite upper portions the curvature of which is substantially equal to that of a larger disc, and opposite lower portions the curvature of which is substantially equal to that of a smaller disc. Thus, the larger disc is held by the upper portions, and the smaller disc is held by the lower portions.

Disc holder for a disc reproducing device

There is provided an optical disc reproducing device, comprising: a frame case having an opening formed on one side thereof; a disc reproducing section disposed within the frame case; a disc receiving section capable of receiving and holding a plurality of discs, the disc receiving section being mainly provided within the frame case adjacent to the opening thereof; a carrier for picking up a selected disc from the disc receiving section and moving the selected disc to the disc reproducing section. Here, the disc receiving section includes a disc holder and a disc cover, the disc holder is provided adjacent to a lower portion of the opening of the frame case in a manner such that the disc holder is pivotable with respect to the frame case, whilst the disc cover is provided adjacent to an upper portion of the opening of the frame case in a manner such that the disc cover is also pivotable with respect to the frame case.

Optical disc reproducing device

Disc reproducing device has a disc holder wherein a plurality of discs are horizontally arranged. A disc player is provided to be moved in parallel to an axial direction of the discs. A loading device is provided to load the disc on the disc player. The loading device has a first arm and a second arm which are rotatably provided in a plane perpendicular to the axial direction, and arranged so as to grip the disc to carry it.
