Title:
PAPER FEEDER IN IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JPS6087137
Kind Code:
A
Abstract:

PURPOSE: To permit the transportation by pushing the rear edge of an excessively thin form-sheet, form sheet having a warped rear edge, etc. by transferring the form-sheet by pushing the rear edge and floating-up the piled form-sheets from the form sheets in transportation.

CONSTITUTION: A rear-edge pushing member 10 fixedly installed onto a main shaft 7 revolves leftward as the main shaft shifts, since the pin 10a1 of the member 10 is in a groove 11a. The lowest sheet of the piled form-sheets is separated and driven-out by the leftward revolution of a paper feeding roller 5 and the action of a gap 1a between a separation restricting member 1. When the main shaft 7 transfers, the pin 10a1 of the rear edge pushing member 10 is released from the groove 11a, and said member 10 runs onto the upper surface 11b of a guide rail 11, together with the pin 10a2. Therefore, the paper feeding roller 5 stops revolution, and the rear-edge pushing member 10 catches the rear edge of the form-sheet by the part 10b and transports said form-sheet through the transfer of the main shaft 7. Since the surface 10c of the rear-edge pushing member 10 pushes upward and floats up the remaining form-sheets in loaded state, if the main shaft 7 shifts in the direction of arrow, the application of the weight of the form-sheets left in the paper feeding apparatus is prevented.
