Abstract
PURPOSE:To perform reduced or enlarged copying while selecting a copying paper suited for a document sheet size by detecting the maximum size of the document sheet placed in a document tray arranged on the upstream side of a platen and detecting the size of the document sheet passing through a paper sheet transfer passage. CONSTITUTION:Various sizes of documents G are placed in a document tray 5 arranged on the upstream side of a platen glass 1. The maximum size of the documents G is detected with optical sensors 13-16 arranged in the tray 5. The documents G sent one by one by a pickup roller 6 into the gap between the roller pair 7, 8, passage of all the documents G are detected with an optical sensor 17, and the front ends of the documents G are trued up with a resist roller pair 9. Determining the length of the document being passed through in the direction of the document flow by means of the turning number of a slit plate 19 being in linked motion with the resist roller pair 9 and a sensor 20, the required document G is sent to the platen glass 1. Specifying the required number of copies and the size with an operation button, the required paper sheets are sent out of a cassette. In this way, copies of the full size, reduced size and enlarged size are freely selected.
