ABSTRACT:
A tape driving mechanism has a pin projecting from a base plate of a tape recorder, a capstan shaft rotatably mounted on the base plate and a pinch roller holder rotatably mounted on the pin. The mechanism further comprises a pinch roller rotatably mounted on a first end portion of the pinch roller holder opposite to the pin, a torsion coil spring and an urging member. The torsion coil spring is provided on a portion of the pinch roller holder with both ends of the torsion coil spring in engagement with other portions of the pinch roller holder. The urging member urges an end portion of the torsion coil spring to rotate and urge the pinch roller holder to resiliently press the pinch roller against the capstan shaft.
