摘要

Improvements in the drive devices of recording devices, characterized by comprising the arrangement of a system of two arms articulated to each other and driven by a single movable pivot, one of them being carrier of the support roll of the tape and carrying mounted the second, a magnetic head for recording and reproducing the tape, the actuating pin being housed in the coincidence zone by superimposing two orifices arranged angularly to each other respectively on said tilting arms, allowing simultaneous separation or approximation both of the roller and of the magnetic head for a rectilinear drive of the pivot.
