ABSTRACT:
A tape recorder has a forward/reverse switching mechanism for switching between forward travel and reverse travel at normal speed, and a track switching mechanism for supporting a recording/playback head to be pivotal between positions where the recording/playback head is aligned with tracks of the tape in forward travel and reverse travel at normal speed. In response to the switching operation of the forward/reverse switching mechanism, a control lever is pivoted in one direction by a cam portion of a gear to selectively engage projections with projections of a driving shaft to rotate it in different directions. The track switching mechanism is driven by the drive slider which is slid in different directions upon movement of the driving shaft.
