Abstract
Apparatus for pushing out a disc placed on a tray between a pair of rollers, in a stable state including a pair of pushing-out mechanisms actuated by a return spring each provided with a pair of fixed shafts. For turning the pushing-out mechanism a device, such as a lever, operates against a pressing force of the return spring, and the pushing-out mechanism is engaged with a separation cam for controlling the insertion and/or the discharge of the disc.
Claims6
A disc recording and/or reproducing apparatus, comprising:
- a plurality of stacked disc placing means for placing at least one disc;
- a pair of pushing-out means for pushing out a disc at a position of insertion and/or discharge from one of said plurality of disc placing means having placed said disc at said position of insertion and/or discharge;
- and
- a pair of position controlling means for controlling insertion, discharge and/or support of the disc, one of said pair of position controlling means being provided on either side of each of said plurality of disc placing means,
- wherein each of said pair of pushing-out means is engaged with each of said position controlling means.
A disc exchanging mechanism comprising:
- a plurality of stacked disc placing means for placing a disc;
- a plurality of a pushing-out means for pushing out a disc at a position of insertion and/or discharge from one of said plurality of disc placing means having placed said disc at said position of insertion and/or discharge;
- and
- a pair of a position controlling means for controlling insertion, discharge and/or support of the disc, one of said pair position controlling means being provided on either side of said disc placing means,
- wherein each of said plurality of pushing-out means is engaged with each of said pair of position controlling means.
A disc recording and/or reproducing apparatus, comprising a pushing/pulling means for pushing/pulling a disc to/from a disc recording and/or reproducing apparatus and including a pair of vertically arranged rollers that contact a circumferential edge of the disc and a pair of levers that contact the circumferential edge of the disc, so that vectors of resultant forces applied by said pushing/pulling means pass through an axial center of said disc.
A disc exchanging mechanism comprising a pushing/pulling means for pushing/pulling a disc to/from a disc recording and/or reproducing apparatus and including a pair of vertically arranged rollers that contact a circumferential edge of the disc and a pair of levers that contact the circumferential edge of the disc, so that vectors of resultant forces applied by said pushing/pulling means pass through an axial center of said disc.
