ABSTRACT:
First and second rotation-transmitting portions are integrally provided for a rotor which constitutes part of a motor. A rotary member is provided in opposed relation to the first rotation-transmitting portion. This rotary member remains in non-coupling condition to the first rotation-transmitting portion in the stopped or rest condition of the recorder, but is coupled to the first rotation-transmitting portion upon sound reproduction (sound recording) and then, upon the completion of sound reproduction, brought to the non-coupling condition to the first rotation-transmitting portion. In addition, in the course of the rotation of the aforenoted rotary member coupled to the first rotation-transmitting portion, a driving member or plate mounting a pinch roller and the like thereon is moved to a sound-reproducing (sound recording) position. Furthermore, an endless belt is trained around the second rotation-transmitting portion and a swinging mechanism serving as a rotating medium for use in fast feeding and rewinding of a tape, therebetween. A turn table on a take-up side or a pay-out side is driven, depending on the rotational direction of the second rotation-transmitting portion, thereby allowing a fast feeding or rewinding operation. As a result, the sound-reproduction (sound recording), fast feeding, and rewinding of a tape may be achieved by means of a single motor, a drive mechanism provided for the aforenoted driving member, and a swinging mechanism cooperative with a rotor which forms part of the motor.
