Abstract

PURPOSE: To prevent damage of a form and the fault of a device, by making it possible to detect automatically and rapidly the jam for form suction and the jam for line feed and ejection.
CONSTITUTION: Driving roller 8 is driven by driving pulse motor 7 to such the form, and pulse motor driving clock 5 is applied to up/down counter 9, and clock 5 for suction are counted; and when form upper end detecting means 13a detects the form upper end, gate 17 is closed to terminate form suction. Then, contents (n) of counter 9 and contents (m) set to form maximum length set value generating circuit 18 are compared with each other by the first comparing circuit 10, and jam is detected for n>m, and pulse motor driving circuit 6 is reset. At the line feed time and the ejection time, pulse motor rotation direction switching circuit 4 is set to the inverse rotation, and counter 9 is down-counted by clock 5; and when count contents become zero, they are applied to the second comparing circuit 12 through decoder 11 and are compared with the output of form lower end detecting means 13b, thereby detecting jam.
