Abstract

PURPOSE: To secure a quick stop control without giving any damage to the tape, by separating and driving the pinch roller after giving a stop command to the capstan when a tape sag is detected.
CONSTITUTION: The undesired sag caused to the travelling tape 11 is detected by the light emitting elements 23 and 24, and the sag occurrence detecting signal is delivered from the comparator 31. Thus a stop command is given to the servo motor 36 from the servo control circuit 35 to give a braking to the travelling of the tape 11. Thus the tape speed is reduced. After this, a command is given to the plunger driving circuit 42 by the signal delayed through the shift register 38. Thus the pinch roller 17 is separated from the capstan 16 to cut the driving force of travel of the tape 11. As a result, the lead-out of the tape is stopped quickly.
