Abstract

PURPOSE: To extend a period of cleaning and maintenance of a roller and prevent damage of a document or the like, by constituting the above described device for a copying machine or the like in such a manner that its feed roller is formed large in diameter and circumferential speed of the feed roller is arranged equal to conveyed speed of a paper sheet.
CONSTITUTION: Document paper 2 is fed between a feed roller 11 and separator roller 12, separated sheet by sheet and fed between the feed roller 11 and a feed roller 13 against a turning effect of the separator roller 12, then conveyed speed of the document paper 2 coincides with circumferential speed of the feed roller 11. Then the document is fed to conveying rollers 7 and carried out to a document insertion port 4a. In this way, a large diameter of the feed roller 11 reduces its contact frequency to a paper sheet, then a stain of the roller can be decreased to extend its cleaning and maintenance period, simultaneously a paper jam in a conveyance passage and damage of the paper sheet can be prevented.
