Abstract

PURPOSE:To prevent a sheet stacking plate in a paper feed cassette, sheets and a paper feed roller from being broken or deformed, by providing a member having an axially tapered part coaxial with the shaft of the paper feed roller on the insertion port side of a paper feed section. CONSTITUTION:When a paper feed cassette 1 is inserted through an insertion port 19 so as to be loaded, if no semicircular paper feed roller 16 is present at a predetermined position, a sheet stacking plate plate 2 in a paper feed cassette 1 or transfer sheets abuts against a semicircular member 17 as shown by the two-dotted-chain line. Further, it is pushed down along a tapered part 17a overcoming a compression spring 3, to such a degree that it does not abut against the semicircular paper feed roller 16, and is advanced to a predetermined paper feed position so that it is released from the contact condition with the semicircular member 17 just before it is completely contact with the paper feed roller 16. Further, if the semicircular paper feed roller 16 is present at the predetermined position, since the semicircular member 17 is not present at the position where it abuts against the sheet stacking plate 2 or the transfer sheets, the paper feed cassette 1 may be loaded in conventional manner.
