PURPOSE:To automatically obtain plural types of copies at one copying operation and automatically copy on two types of copying paper from one face to be copied by inputting plural types of sheets at a time. CONSTITUTION:A both side mode or a composite mode is set by a key and, as printing is started through a start key 55, C1 sheets of first-side copied paper enter a both side tray 22. At this time, the reading of a sheet counting counter C6 is increased to, C1=C6. Then, when all sheets of the first-side copied paper entered the both side tray 22, the copying mode is automatically changed to a second side copying mode and the sheets of paper are fed from the both side tray 22 at the start of the next printing. And, after carrying out C1 times of second side copying, the sheets of paper are discharged. At this time, the reading of a counter C0 for detecting the number of sheets of paper in the both side tray is decreased to zero. When this operation is over, the copying mode returns to a first side mode. |
