Abstract
A disk changer for selecting and drawing disk trays from a disk tray drawer using the same motor for both elevational movement of the disk changer and lateral/horizontal movement of the disk tray lever. An idler gear, which is driven by the motor, is selectively engaged with an elevational control gearing mechanism and a lateral movement gearing mechanism. A power switching plate having cam grooves therein controls position changes of the idler gear.
Claims5
A disk changer driving apparatus of a multi-disk player comprising:
- a drawer having multiple disk trays placed therein;
- a disk changer positioned with respect to said drawer so as to be movable to be positioned opposite said selected disk trays;
- drawing lever driving means for driving a drawing lever to extract and replace selected disk trays, said drawing lever driving means having a plurality of first connecting gears successively engaged with one another;
- disk changer driving means for driving said disk changer to positions opposite selected disk trays, said disk changer driving means having a first elevating gear;
- a motor;
- and
- power switching means for switchably transmitting the power of said motor selectively to said first elevating gear of said disk changer driving means and a first of said plurality of first connecting gears of said drawing lever driving means, wherein said power switching means comprises:
- a driving gear rotatable by said motor;
- an idler gear engaged with said driving gear;
- a cam plate having a cam surface, said idler gear moving along said cam surface of said cam plate to alter the position of said idler gear between a first position where it engages and drives said disk changer driving means and a second position where it engages and drives said drawing lever driving means;
- and
- means for controlling the position of said cam plate to select the engagement of said idler gear and said disk changing driving means and said drawing lever driving means.

- a drawer having multiple disk trays placed therein;
- a disk changer positioned with respect to said drawer so as to be movable to be positioned opposite said selected disk trays;
- drawing lever driving means for driving a drawing lever to extract and replace selected disk trays, said drawing lever driving means having a plurality of first connecting gears successively engaged with one another;
- disk changer driving means for driving said disk changer to positions opposite selected disk trays, said disk changer driving means having a first elevating gear;
- a motor;
- and
- power switching means for switchably transmitting the power of said motor selectively to said first elevating gear of said disk changer driving means and a first of said plurality of first connecting gears of said drawing lever driving means, wherein said power switching means comprises:
- a driving gear driven by said motor;
- an idler gear engaged with said driving gear and selectively engaged with the first connecting gear of said disk tray drawing lever driving means and the first elevating gear of said disk changer driving means, respectively;
- a power switching plate engaged with said idler gear and biased by a torsion spring to force said idler gear into engagement with said first elevating gear and out of engagement with said first connecting gear of said disk changer drawing lever driving means;
- and
- a push lever movable from side to side by a solenoid into and out of engagement with said power switching plate to cause said power switching plate to move against the bias of said torsion spring, thereby causing said idler gear to disengage from said first elevating gear and to engage with said first connecting gear of said disk tray drawing lever driving means.
