Abstract

PURPOSE: To certainly feed an original one by one separately, by swinging an original lifting member almost perpendicularly to an original placing tray.
CONSTITUTION: Separating sheet 20 with turning shaft 19 fixed is inserted into opening 21 of tray 1 and pressure contacted to original feed roller 2, and member 22 for lifting placed originals O from the tray surface is fixed to shaft 19 in a conventional automatic feeder. Member 22 is swinged almost perpendicularly to the tray face in synchronism with the yielding movement of sheet 20 caused by passing of original O between roller 2 and sheet 20. When the uppermost first original O1 is fed by rotating roller 2 in the arrow direction, the friction force between original O1 and roller 2 is made stronger than that between original O1 and sheet 20 by selecting strength of spring 24, material and shape of roller 3, and angle θ between tray 1 and sheet 20.
