Abstract
PURPOSE: To make constitution simple by logic-processing the state detection pulses such as of stop, tape end, etc. and the set signal according to modes.
CONSTITUTION: The tape end detecting circuit 5 of an operating part 1 generates the first pulse of the width determined at the stop detection of a tape or the detection of the tape end. The third pulse of the same beginning end as that of this pulse and a narrower width is generated from a pulse switching circuit 7 and further the second pulse of narrower width than the first pulse is generated from a timer circuit 6 upon lapse of the specified time after turning on of power source. The first pulse appears at the final end of the second pulse and is applied together with the set signal corresponding to the mode having been coupling processed and selected so as to inhibit the appearance of the first pulse in the third pulse period to a logic processing circuit 2, whereby the solenoid driving circuit and motor driving circuit or other cooperating with the solenoid timing circuit of the drive part 3 are controlled.
