ABSTRACT:
A digital full-color copying machine (1) has a full-size mode for copying the entire extent of an original document (210) and a normal mode for copying the original document except for peripheral edge portions. When the normal mode is selected, the original document is conveyed to a position wherein a rear side edge of the original document contacts and is aligned by a fixed scale (205) provided at a side edge portion of an original document glass table (29) and a leading end edge of the original document contacts and is aligned by a movable scale (120) provided at a leading end portion of the original document glass table (29). When the full-size mode is selected, the original document is conveyed and positioned at a modified position with the rear side edge of the original document being aligned by the fixed scale (205) but with the leading end of the original document being spaced a specified distance from the movable scale (120). The reverse start position of the first slider (211) of the copying machine for the full-copy mode is spaced a specified distance from the reverse start position for the normal copy mode.
