ABSTRACT:
A system for cleaning a magnetic head provided inside a rotary drum installed on a chassis in cooperation with a mechanism for guiding a tape. The system has a cleaning device including a cleaning lever capable of pivoting freely, supported by a pivot secured to the chassis, a cleaning member, a spring for urging the cleaning lever so that the cleaning member may contact with the rotary drum and a pin fixed on the cleaning lever. The system also has a tape guiding mechanism including tape guiding members and a drive member for shifting the tape guiding members, capable of pivoting freely. The arrangement permits cleaning of the magnetic head by making the cleaning member contact with the rotary drum, and also permits separation of the cleaning member from the rotary drum by making the drive member contact with the pin. The cleaning member is supported by a shaft inclining from an axis perpendicular to a reference surface of the rotary drum and having a length sufficient to reach a position corresponding to the top portion of the drum, and adapted to be shifted upward along the shaft while rotating a cleaning operation.
