PURPOSE: To prevent defective transport of document by constituting one part of a positioning member so as to be rotatable and separatable against a paper feed table, and loading the rear end in transport direction of the lowermost document sheet on a projecting part when a document bundle is loaded on the paper feed table.

CONSTITUTION: A rotation member 12 rotatable and separatable against a paper feed table 3 is provided on an end plate 6, a projecting part 12a is formed on the lower end part of the rotation member 12 so as to project in the transport direction of a document bundle P, and when the document bundle P is loaded on the paper feed table 3, the rear end in the transport direction of the lowermost document is loaded on the projecting part 12a. Consequently, when the document bundle P after completing copy is taken out, the rotation member 12 is rotated to separate the rear end part in the transport direction of the document bundle P from the paper feed table 3, and the document bundle P can be easily removed. Hereby, workability of taking out work of the document bundle P is improved and defective transport of the document can be prevented.
