Abstract

PURPOSE: To feed out the sheet in a stabilized condition, by providing an auxiliary roller, of diameter smaller than that of feed roller, coaxially to the feed roller.
CONSTITUTION: Coaxially to a feed roller 21, is provided an auxiliary roller 22 of diameter smaller than that of the feed roller 21. This auxiliary roller 22 is always contacted to a mounting topmost sheet, to depress positioning the mounting sheet to a prescribed position. In this way, a clearance between a height position of the mounting sheet and the feed roller 21 can be optionally determined, enabling a less amount of sheet depression by the feed roller 21 at the time of feed operation, and a shock, generated between the feed roller and the sheet when operated a feed, can be remarkably made smaller than conventionally generated. Consequently, a turn over of sheet when operated a feed or a bounding motion by a shock of the feed roller, further unequalized press contact, between the sheet and the feed roller 21, can be prevented, thus can be fed the sheet in a stabilized condition.
