Abstract

PURPOSE:To permit a document in a fixed position to efficiently bite into a paper feed part by providing a number of ribs extending in a direction of paper feed on the upper surface of a document stacker and a rotary member, having a part protruding from an upper edge of the rib and a part being recessed from it, in the vicinity of the paper feed part. CONSTITUTION:Two or more ribs 3a, extending in a paper feed direction, are protrusively provided on the upper surface of a document stacker 3, while two or more protruding pieces 7a are provided corresponding between the ribs 3a in the bottom end edge of a gate member 7, being formed into a comb tooth shape. Thus deforming a document 4 on the stacker 3 into a corrugated pattern by the rib 3a and the protruding piece 7a, the document 4 during its feed provides the rigidity, while the return document 4 effectively prevents its point end from being placed under a gate. The gate member 7 is placed in a rising position when the document 4 comes to be advanced by the extruding action of a rear end restricting plate, and when the point end of the document reaches a detecting position of a stack sensor, the gate member 7 is placed under its own weight on the document 4, retaining it. Because of the rigidity provided in the document 4 as described in the above, the document 4 in the fixed position can be fed efficiently biting into a paper feed part.
