Abstract
PURPOSE: To cut roll paper by the same length as that of an original, by automatically changing the generation timing of a cutting signal for cutting the paper in accordance with the original length.
CONSTITUTION: Roll paper is fed with paper feed roller 13 in a paper feeder, and is cut with a cutter 19. Roller 13 is connected with motor M always rotating through clutch CL, and clutch CL and cutter drive circuit 18 are controlled by signals 16', 17' from paper feed control circuit 14. Circuit 14 comprises control signal circuit 15, timer 16, 17, and original length correcting circuit 20, and receives original detection signal 10' from original detecting circuit 10. Control signal circuit 15 delays signal 10' by a constant time, differentiates the rise and breaking of signal 10' to send the differentiated rise output as wave shaped signal 15' and the differentiated fall output as wave shaped and reversed signal 15". Signal 15' accords the ends of the roll paper and the original, and signal 15" stops paper feed to cut the paper with cutter 19.
