Abstract

PURPOSE:To improve the processing efficiency and operation of a magnetic tape, by automatically running and stopping the tape by detecting a plurality of end marks on the magnetic tape. CONSTITUTION:At the lower edge of tape 1, tape terminal mark 2 is provided and at a certain distance from mark 2, tape end mark 3 is provided. When mark 2 is detected 9 during tape processing, detecting circuit 13 operates to supply a detection signal to AND gate 14 and when mark 3 is detected 8 and 9 next, the output of gate 14 receiving detection signals of detecting circuits 12 and 13 is obtained from gate 14 and supplied to tape driving circuit 15, whose output controls driver 10 to stop the run of tape 1. Further, the detection signal is stored in FF16, from which an error report signal is sent to upper priority device 17.
