Abstract

PURPOSE: To enhance operability remarkably, by controlling scanning stroke of scanning means by means for detecting the size of copying paper manually inserted.
CONSTITUTION: In manual insertion copying, a sheet inserted from stand 12 is detected with detector 15, and after a given time it is fed into the copier by driving feed roller 14. During the given time (about 2 seconds) slant insertion of the sheet or the like can be corrected. Detection of sheet insertion by detector 15 stops sheet feed from a cassette. Sheet detector 16 controls the stroke by judging the sheet size from whether detector 16 detects the sheet of not at a predetermined time, thus permitting copying to be started only by inserting the sheet without turning on a copying switch in an operating unit, and correct sheet position to be held in feeding the sheet into the copier.
