Abstract

PURPOSE:To detect te thickness of paper, by providing a paper-reduction detecting means and a paper-sheet counting means in a paper processing device of a copying machine and the like having an elevator tray. CONSTITUTION:A paper-reduction detecting means 3 detects the time when the decrease of the position of the paper at the topmost layer of paper stocked in an elevator tray 2 exceeds a preset limit. A paper-sheet counting means 4 counts the number of the sheets of paper, which are supplied in one cycle, during which the tray 2 is lifted by the detected signal from the detecting means 3, the paper is supplied, the position of the paper at the topmost layer exceeds the preset limit, and the detected signal is generated. A paper-thickness computing means 5 computes the thickness of paper based on the counted number of the sheets of paper and the preset limit. Thus the thickness of the paper can be detected.
