Abstract:
1. A method which is applied to a paper handling device for detecting a height of a paper bundle, comprising: applying pressure on the paper bundle externally inserted which is piled at least one paper, in a piled direction of the paper bundle; detecting a height of the paper bundle in a state where the pressure is applied; and calculating a maximum number of pieces of paper anticipated to be subsequently inserted based on a height detected for each paper bundle already inserted and a predetermined upper limit of height of each of the paper bundles, when the paper bundle to be handled together can be inserted in the paper handling device over a plurality of times; wherein the maximum number is calculated by using a thickness of one piece of paper, the thickness being calculated based on the number of pieces of the paper fed out from the paper bundle and the height detected for each paper bundle.
