Claims

[Scope of utility model registration request]

a cam plate having first and second cams that are rotated when switching operation modes; a control lever that is controlled by the first cam of the cam plate and moves the head base back and forth; and a control lever that is controlled by the second cam of the cam plate. The reel is composed of a swing arm that slides a selection lever that determines the direction of rotation of the reel, and the first cam is controlled by forming a groove in a part with a cam base and a wall cam. A tape recorder drive mechanism characterized in that a spring is provided to bias the tape in one direction, and the head base is rapidly moved by the spring force as the cam plate rotates.
