<p>PURPOSE:To prevent the occurrence of accidents owing to crease, etc. of the roll paper having been cut by forcefully cutting the roll paper being conveyed by the maximum length cut signal. CONSTITUTION:When a switfh SW2 is operated, the reset output of an FF 5 causes an automatic cutting display lamp L2 go on and an AND gate 9 to open. Then the timng signal of the preset timing is outputted via the gate 9 and roll paper is automatically cut to a specified length. When a switch SW1 is closed, a manual cutting lamp L1 is lighted by the set output of the FF 5, and a lamp L3 is lighted by the set output of an FF 6 by the trailing end detection signal of the original, by which deliverying out of the roll paper of the same length as that of the original is checked. The roll paper is cut by the output of an AND gate 8 as a switch SW3 is oeated. On the other hand, when the maximum length cutting signal through counting of clocks corresponding to the maximum feed length is applied to an OR gate 10, the roll paper is cut in either case of manual and automatic cutting, thus the cutting of the roll paper for more than a specified length is defined.</p> |
