<p>PROBLEM TO BE SOLVED: To enhance workability by judging the residual loading possible number of sheets of a paper discharge tray by a loading calculating means, displaying its value by a loading display means, and judging whether or not it can be housed when transfer paper already housed in the paper discharge tray is removed. SOLUTION: When a series of copying action to house a transfer paper sheet in a paper discharge tray 1 is completed by performing a copying action on the transfer paper sheet, a CPU 30 calculates the loading possible number of sheets from positional information on the paper discharge tray 1. In this case, for example, when the whole moving distance of the paper discharge tray 1 is denoted by 300mm, since transfer paper sheets can be loaded by about 150 sheets to a moving distance 40mm, whether or not a position of the paper discharge tray 1 exceeds 240mm is judged, and in the case of YES, the loading possible number of sheets is set to 150 sheets, and in the case of NO, whether or not it exceeds 200mm is judged. Here, in the case of YES, the loading possible number of sheets is set to 300 sheets, and in the case of NO, and when it exceeds 160mm, the loading possible number of sheets is set to 450 sheets, and these are respectively displayed on a display part.</p> |
