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.

Disc loading device

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.
