Claims

[Claims for Utility Model Registration] (1) A drive motor, a capstan drivingly connected to the drive motor, a swingable arm member, and a swingable arm member rotatably disposed on the arm member and abutting the capstan. A pinch roller that can be separated freely,
A cam contact portion integrally provided on the arm member, an elastic member that elastically biases the arm portion in a direction in which the pinch roller contacts the capstan, and the cam contact portion slide into contact with each other to cause the arm to contact the arm member. A cam body that swings the member, and a pinch roller that is separated by forward rotation of the drive motor, swings the cam body by an angle at which it comes into elastic contact with the capstan, and the pinch that is brought into elastic contact by reverse rotation. A tape recorder comprising: cam driving means for swinging the cam body in the opposite direction by an angle at which the roller separates from the capstan. (2) The cam driving means drivingly connects a driving gear to the capstan, a fan-shaped gear capable of meshing with the driving gear is integrally provided on the cam body on the same axis, and the cam driving means connects the driving gear to the driving motor. A pulley connected for driving is brought into elastic contact via a friction member, and the cam body is swung by the frictional resistance force generated by the rotation of the pulley driven by the reverse rotation of the drive motor, so that the fan-shaped gear meshes with the drive gear. 2. A tape recorder according to claim 1, characterized in that the tape recorder is configured to allow the user to:
