Correction 1984. 7.16 The claims for utility model registration and the brief description of the drawings are amended as follows. 0 Utility Model Registration Scope of Claim Between the supply reel stand and the take-up reel stand, it is possible to selectively abut the pulleys of both reel stands, and also to be able to come into contact with and separate from the drive rotating body, and to be in contact with the drive rotating body. A rotating body that receives the rotational force is rotatably provided on a rotating plate, and when the rewind operating lever and the fast forward operating lever are in a stopped state, pins provided on the rotating plate are attached to part of the opposing portions of the rewind operating lever and fast forward operating lever from both sides. Convex portions for positioning at the neutral position are provided, and concave portions facing each other are provided following these convex portions, so that when the pin of the rotating plate is positioned at the neutral position by the two convex portions, the rotating body is held at a neutral position where it does not come into contact with either the pulleys or the driving rotary body, and springs are interposed between the rewind operating lever and the rotating plate, and between the fast forward operating lever and the rotating plate, respectively. When both the springs are in a stopped state, no spring force acts between the levers and the rotating plate, and when the rewind operating lever or the fast forward operating lever is operated, the convex portion of the operated operating lever is By moving, the restriction on the position of the pin of the rotating plate is released, and the spring interposed between the operating lever and the rotating plate causes the pin of the rotating plate to move into the recess of the operating lever that has been moved.

Claims (1)

[Scope of utility model registration request] Between the supply reel stand and the take-up reel stand, a rotating body that can selectively come into contact with the pulleys of both reel stands and receives rotational force from the drive rotating body is rotatably provided on the rotating plate, and when the reel stand is stopped, the winding The position of the rotary plate is controlled by the return operation lever and the fast-forward operation lever to hold the rotating body in a neutral position where it does not come into contact with any of the pulleys, and the rewind operation lever, the rotation plate and the fast-forward operation are controlled. A spring is interposed between the lever and the rotating plate, and the spring prevents the spring force from acting between the levers and the rotating plate when both are in a stopped state, and the rewinding operation lever or When the fast-forward operation lever is operated, the position restriction of the rotary plate is released, and the spring interposed between the operated operation lever and the rotary plate rotates the rotary plate, and the rotating body is moved to the position described above. A magnetic recording/reproducing device characterized in that the elastic force of a spring selectively presses against a pulley of a supply reel stand or a pulley of a take-up reel stand to perform unwinding and rotation of the reel stand during fast forwarding.゛
