Abstract

PURPOSE:To always stop a cam at a set position, by feeding the set position signal supplied from a cam position switch back to a control circuit and thus correcting the overrun of a motor that drives the cam. CONSTITUTION:A control circuit (micro CPU) 14 drives a driving circuit 17 of a driving motor 16 by the designation given from a working position designating switch 15. Thus a cam is driven by the motor 16 to set a tape recorder at a desired working position. Accordingly a mobile contact 2 of a cam position switch interlocking the cam moves, and the set position signal corresponding to the selected working position is fed back to the circuit 14. Receiving this signal, the circuit 14 makes sure whether the cam position switch is on a desired contact when the motor 16 stops. In the case of an overrun, the motor 16 is turned for correction. As a result, the cam can always be stopped at the set position.
