Claims

[Claim for Utility Model Registration] In a magnetic recording/playback machine using a cassette, a semiconductor motor is fixed on the main body deck at an intermediate position on a straight line connecting both the winding and feeding reels, and the motor rotates. a rotary lever that is loosely fitted to the shaft and frictionally coupled to the shaft, and a first rotary lever that is rotatably supported by a support shaft installed at the free end of the lever and fixed to the rotary shaft.
When the second gear meshing with the second gear and the lever mentioned above are rotated in the same direction by the left and right rotation of the electric motor, when they rotate to the left and are on a straight line connecting both reels, When it rotates and is on a straight line connecting both reels,
The lever comes into contact with the first and second two contact pins planted on the top surface of the motor, and the first contact pin, so that a portion of the lever mentioned above contacts and stops at each position. a third gear provided to rotate coaxially and synchronously with the take-up reel so as to mesh with the second gear at the position;
At the position where the lever is in contact with the second contact pin, the second
a fourth gear coaxially and synchronously rotated with the payout reel so as to mesh with the gear; and a mild steel disk whose center is fixed to the rotating shaft of the electric motor. A field magnet is loosely fitted onto the rotating shaft using the disk as a yoke, and a motor is configured to rotate at a predetermined output torque in playback mode, and to rotate left and right at high speed in fast forward and rewind modes. 1. A reel drive device comprising: a control circuit for controlling an armature current of an electric motor;
