ABSTRACT:
A detection sensor detects a position of a level detection lever that touches an uppermost sheet of sheets stacked on a holding tray, and a computing device counts the number of sheets that have been discharged to the holding tray. A judging device judges the amount of sheets stacked based on a sheet surface level detection signal from the detection sensor and a count value of the computing device. The apparatus accurately judges that the maximum amount of sheets have been stacked in the holding tray according to the position of the level detection lever and a count value for a number of sheets. Also, the apparatus selects one of a plurality of values for an offset sheet count, which corresponds to the operating conditions, namely the transporting speed of sheets, the intervals between sheets, and the length of the transport direction of the sheets.
