Claims

[Scope of utility model registration request]

A first take-up reel shaft and a first rewind reel shaft for winding and rewinding the first magnetic tape; a second take-up reel shaft and a second winding reel shaft for winding and rewinding the second magnetic tape; A tape recorder in which a return reel shaft and a return reel shaft are arranged point-symmetrically on a fixed substrate, and a drive gear whose rotation of an electric motor is transmitted by a belt and which is rotated in forward and reverse directions by forward and reverse rotation operations of the electric motor; first and second intermediate gears that are always in mesh with each other, and are rotatably mounted coaxially with the axis of the first intermediate gear, and are rotated in the direction of rotation by the force received from the first intermediate gear. a first rotating member that receives a rotational displacement force; and a first rotating member that is rotatably mounted coaxially with the axis of the second intermediate gear, and is rotated in the rotational direction by the force received from the second intermediate gear. a second rotating member that receives a displacement force; a first transmission gear that is rotatably attached to the first rotating member and meshed with the first intermediate gear;
a second transmission gear rotatably attached to the rotating member and meshed with the second intermediate gear; a second transmission gear provided to rotate integrally with the first take-up reel shaft; a first take-up reel gear that meshes with the first transmission gear when the first rotating member is in the fast-forward operation position; and a first take-up reel gear that is provided to rotate integrally with the first unwind reel shaft a first unwinding reel gear that meshes with the first transmission gear when the rotating member is in the unwinding operation position; a second take-up reel gear that meshes with the second transmission gear when the rotating member is in the fast-forward operation position; and a second take-up reel gear that is provided to rotate integrally with the second unwind reel shaft, A second rewinding reel gear that meshes with the second transmission gear when the moving member is in the rewinding operation position, and a rotational displacement operation of the first rotating member to the fast forwarding operation position and the rewinding operation position are controlled. A reel shaft drive device for a tape recorder, comprising a first control member that controls rotational displacement of the second rotational member to a fast-forward operation position and a rewind operation position.
