摘要： 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.

摘要： An apparatus for varying the tension of a belt in a portable audio logic deck is provided. The belt tension varying apparatus includes a main base, a driving source installed in the main base, a pulley which transfers a driving force of the driving source while being wound by a belt and a main slide linearly reciprocating by the driving force of the driving source. A lever member is pivotably installed in the main slide and has an end portion connected to the rotational axis of the pulley. An elastic member elastically supports and biases the lever member in one direction, and a varying unit adjusts the tension of the belt wound around the pulley by pivoting the pulley, via the lever member, in response to the linear reciprocating movement of the main slide.
