Abstract

PURPOSE: To provide the title feeder simple in structure and easy to handle, by contacting a separating sheet to an original feed roller with pressure keeping a cirtain angle to an original placing tray.
CONSTITUTION: Separating sheet 20 is fixed to turning shaft 19 of a conventional automatic feeder, and inserted in opening 21 of original tray 1, and pressure contacted to roller 2 having angle θ2 to tray 1. Original lifting member 22 is fixed to shaft 19, and part 22a of member 22 penetrates through opening 23 of tray 1 to lift original O. A pressure contact force to roller 2 is given to sheet 20 with coil spring 24 wound about shaft 19. Roller 2 is rotated in the arrow direction to feed the uppermost first original O1. At that time, the friction force between roller 2 and original O1 is made greater than that between original O1 and sheet 20 by selecting strength of spring 24, material and shape of roller 3, and angle θ2 between tray 1 and sheet 20.
