Belt tension varying apparatus for portable audio logic deck

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.
