Disc changer device

A disc changer device, for exchanging a plurality of discs at a disc exchange position outside of a chassis, housing the discs at a stand-by position in the chassis, and transporting a disc selected from the discs to a disc recording/reproducing position inside the chassis where a recording or reproducing operation of information signals is carried out on the disc, comprising:

• a plurality of trays on which the discs are placed to be moved virtually in parallel with a main face of each of the discs, and which are stacked virtually perpendicularly to the main face;
• a traverse unit that is provided with an optical pickup for carrying out the recording or reproducing operation of information signals on the discs and a turn table that rotates the discs;
• first and second motors for generating driving forces;
• a pickup moving unit for moving the optical pickup in a radial direction of disc by the driving force of the first motor;
• a disc clamp unit for moving the traverse unit by the driving force of the first motor to a clamp position at which each of the discs on the tray located at the disc recording/reproducing position is sandwiched and held between a damper placed above the disc and the turn table, as well as to a retreat position apart from the disc;
• a first tray driving unit for moving the tray reciprocatingly between the stand-by position and the disc recording/reproducing position by the driving force of the first motor;
• an elevation unit for raising and lowering the traverse unit by the driving force of the second motor to correspond to a height position of the selected disc on the tray located at the disc recording/reproducing position;
• and
• a second tray driving unit for reciprocatingly moving the tray between the stand-by position and the recording/reproducing position by the driving force of the second motor.
