ABSTRACT:
A cassette tape recorder capable of manually switching the operation thereof to any one of a stop, a reproducing, a quick winding or a quick rewinding position.
A swingable switching lever is coupled with an actuating lever, and a frictional driving wheel integral with a driving shaft mounted on the free end of the actuating lever. An idler friction wheel is located at a position opposite to a frictionally driven wheel with respect to the driving shaft. Either the driving shaft or the frictional driving wheel is held disengaged from the frictionally driven wheel or the idler friction wheel when the actuating lever is at the stop position. When the actuating lever is switched to the reproducing position, the switching lever urges the driving shaft to compressively contact with the frictionally driven wheel. When the actuating lever is switched to the quick rewinding position, the switching lever is swung in the opposite direction and urges the frictionally driving wheel to compressively contact with the idler friction wheel integral with the idler gear to drive the rewinding reel mounting shaft at a higher speed.
