Title:

DEVICE AND METHOD FOR FEEDING PAPER

Document Type and Number:

WIPO Patent Application WO/2004/080863

Kind Code:

A1

Abstract:

A paper feeding device has a pick mechanism for taking out sheets of paper by a pick roller (1), the taking-out being performed sequentially from a lower side sheet out of the sheets whose top ends are aligned by a stopper block (2) with the sheets loaded on a shooter. The device further has a roller guide (11) and a butting guide (12). When the roller guide (11) is at a paper set position that is a position to which the roller guide has been lifted in a direction departing from the pick roller (1), the roller guide (11) lifts up the top end portions of sheets of paper to be loaded on the shooter to prevent the contact between the sheets and the pick roller (1). The butting guide (12) aligns the top end portions of the sheets when the roller guide (11) is lifted. At the time of the start of a pick operation, a paper- pressing operation by a pick arm (4) and the regression of the butting guide (12) are performed prior to the regression of the roller guide (11), and the sheet are taken out from a gap formed between the top end of the stopper block (2) and the pick roller (1).
