<p>PURPOSE:To smooth unloading work smooth by providing a control means that moves trays to the home position after duplication is finished, and a control means that shifts trays comparing existence of copying paper by means of a detecting means of paper in each tray with stored number of sort parts. CONSTITUTION:When duplication is finished, the number of original sheets duplicated is judged whether or not it is an odd or an even sheet number, and, when it is an odd sheet number, a tray unit 33 is moved to a home position by the signal of a first control means as the tray unit 33 stops in the state wherein it is shifted upward. Then, when copying paper stored in a sort tray 3 of the first stage is unloaded, existence of paper is detected by a paper detecting sensor 4 at the part of sort tray 3 of the first stage, and, if it is detected that paper does not exist in the tray 3 of the first stage, the number of sort parts previously stored and the number of the stages of the trays wherefrom copying paper is unloaded are compared. When both do not coincide, the sort tray unit 33 is shifted upward to the extent of one stage of trays by the signal of a second control means, and repeat this successively until coincides with the number of sort parts stored.</p> |
