ABSTRACT:
A portable audio logic deck mechanism with a single driving source includes a power transfer unit transmitting power from the driving source, an interlocking unit selectively transmitting power to a pair of reel tables, a recording/reproducing unit performing recording/reproduction on a tape on reel tables, a first mode converting unit converting the rotational speed and direction of reel tables, a second mode converting unit moving the recording/reproducing unit up or down by interlocking with the first mode converting unit, and an ejecting unit to open/close a door. A pinch roller driving apparatus for a portable audio logic deck to adjust a tape running speed includes a pair of guide brackets, a pair of pinch rollers selectively close-contacting the respective rotation shafts of capstan wheels, and a pinch lever which selectively presses the guide brackets to pivot the pinch rollers by pivoting selectively in contact with both ends of the upper protruding portion according to the position of a head slide. An ejecting apparatus for the portable audio logic deck includes a knob having a lock member of which one end is hooked by the door, an ejection lever of which one end is coupled with the knob and having a first stopper, a head lever having a hooking protrusion fitting to a cam groove of a cam gear and a second stopper to selectively face the first stopper and guide the up/down movements of the magnetic head by interlocking with the rotation of the cam gear.
