Document Type and Number:
WIPO Patent Application WO/1996/011111
Kind Code:
A1
Abstract:
This invention aims at preventing the occurrence of the slacking of a form when a continuous form is returned in a printer capable of feeding continuous forms and cut forms. The method of feeding and returning a continuous form according to this invention in a paper feed apparatus having a pin feed unit (7) and frictional feed units (4, 5), the pin feed unit (7) being provided at the upstream side of a continuous form passage, a continuous form (6) being fed by both the pin feed unit (7) and frictional feed units (4, 5), there frictional feed units (4, 5), being driven at a peripheral speed slightly higher than that at which the pin feed unit (7) is driven, characterized in that a first feed rate in a range in which the slacking of the form does not occur between the frictional feed units (4, 5) and pin feed unit (7), and a second feed rate larger than a feed rate difference between the frictional feed units (4, 5) and pin feed unit (7) during the returning of the first feed rate are set, the simultaneous reversing of the frictional feed units (4, 5), and pin feed unit (7) at the first feed rate and the forward rotation of the frictional feed units (4, 5) at the second feed rate with the pin feed unit stopped being alternately repeated, whereby the continuous form (6) is fed and returned.
