Abstract
A disk recording and/or reproducing apparatus includes a cover mounted on a main body for movement between open and closed positions, a disk presser unit operably mounted on the cover of the apparatus such that it cooperates with a spindle drive unit for holding the disk, a holder cover attached to the cover for movement therewith, and a controller to control the holder to permit movement of the disk presser when the cover is in the closed position, so that when the spindle unit and disk table are moved radially relative to the disk, the presser unit is moved as well.
Claims13
A recording and/or reproducing apparatus for a disk comprising;
- a main body having a recess formed therein for accommodating a disk,
- a cover movably mounted on said main body and being movable between a first position to open said recess and a second position to close said recess,
- a spindle unit for rotating a disk and being mounted on said main body for movement in a radial direction relative to said disk when said disk is being recorded and/or reproduced,
- a disk presser operatively mounted to said cover to cooperate with said spindle unit for holding said disk,
- holder means cooperating with said disk presser and being movably attached to said cover to limit movement of said disk presser to radial movement relative to said disk, and
- control means for moving said holder means to permit said disk presser to move with said spindle unit in said radial direction when said cover is in said second position.
A recording and/or reproducing apparatus for a disk comprising;
- a main body having a recess formed therein for accommodating a disk;
- a cover movably mounted on said main body for movement between a first position in which said recess is opened to a second position in which said recess is closed;
- a spindle unit movably mounted on said main body for movement in the radial direction relative to the disk;
- a disk presser operatively mounted on said cover to cooperate with said spindle unit for holding a disk;
- holder means for said disk presser means movably mounted to said cover for limiting movement of said disk presser means to said radial direction;
- and
- control means for moving said holder means to permit said disk presser means to move with said spindle unit in said radial direction when said cover is in said second position, wherein said disk presser means includes a cylindrical mid-portion and an upper ring portion and said holder means comprises a holder plate having an elongated hole of a width to permit passage of said cylindrical mid portion of the disk presser and to obstruct the passage of said upper ring of the disk presser, said hole opening on one side of said holder plate provided in turn with upright bent portions, a supporting shaft attached to an inner surface of said cover, said holder plate being pivotally mounted by said supporting shaft mounted to the inner surface of the cover in a manner so that said one side of the holder plate is movable vertically;
- and said control means comprises a rotary support shaft attached to an inner surface of said cover, and a holder arm pivotally mounted halfway by said rotary support shaft, said holder arm having a pin at one end projecting substantially parallel to said rotary support shaft and engaged in an opening in said holder plate and an abutting portion at the other end in abutment with a fixed pin mounted in said recess in said main body, a coil spring, said holder arm being biased by said coil spring coiled around said rotary support shaft of the holder arm, said holder plate being pivoted responsive to the opening or closure of the cover so that said one side of said holder plate is moved vertically.
