Abstract:
A disk loading mechanism for a compact disk (CD) device, having a reading device for reading a CD, said disk loading mechanism comprising:a frame, an opening formed in said frame, and a transversal rack formed on said frame;a tray, which is slidingly movable within said frame in a longitudinal direction between a loading/unloading position for loading and unloading said CD and a reading position for reading said CD and which has a substantially straight longitudinal rack;a reading device support for supporting said reading device, having a front end and a rear end with two aligned pins, which are oriented in a transverse direction and serve as hinges, such that said front end is allowed a vertical movement; anda transmission unit, movable in a transverse movement between a transverse loading/unloading position and a transverse reading position, said transmission unit comprising:a horizontally disposed base plate which is movable within said opening of said frame;a vertically extending guiding plate affixed on a rear end of said base plate, for causing a vertical movement of said front end of said reading device support upon a transverse movement of said transmission unit;a motor and a set of gears engageable with said motor, both said motor and said set of gears being mounted on said base plate;wherein said set of gears are engageable with either said transversal rack or said longitudinal rack, such that when said set of gears are engaged with said transversal rack, said motor causes a transverse movement of said transmission unit and thus a vertical movement of said front end of said reading device, and when said set of gears are engaged with said longitudinal rack, said motor causes a longitudinal movement of said tray between said reading position and said loading/unloading position.
