Abstract

PURPOSE:To eliminate the mistake of selecting copy paper by dividing the action of auxiliary scanning into the forward action and the backward action, and judging the effective portion where the information of an original document is distributed in the forward action so as to determine the size of paper to be fed. CONSTITUTION:Reflecting light from the scan plane 27 of original document on the document tray 1 is reduced by lens 25 to focuse it on CCD26. The area of an effective portion containing the information 28 on the original document 2 is obtained from the length C of the auxiliary scanning direction with one end E of the document 2 as its reference and slso from the length D of the principal direction with one end F of the specified principal scanning width as its reference. The size of paper to be fed is determined in the electronic circuit C by how many bits there are in connection with line clock and bit clock in CCD26 between the lengths of C and D. Paper feed rollers 13, 15 are operated by the size thus determined, and copy paper, for example, size of B5 or A4 in the feed paper cassettes 14, 16 is selectively fed.
