<p>PURPOSE:To improve stacking property and reduce the loss of lowering time of a tray by providing a filing quantity detecting means, a rising and falling quantity arithmetic means for operating the rising and falling quantity of the tray according to the filing quantity, and a driving part control means for controlling a driving part on the basis of the operation result. CONSTITUTION:A stacking device body 11 has a filing unit 13 for filing a plurality of sheets; a tray 16 for stacking the filled sheets filed in the filing unit 13; and a driving part 17 for raising and falling the tray 16. Such a filed sheet stacking device 1 has a filing quantity detecting means 62 for detecting the filing quantity of filed sheets; a rising and falling quantity arithmetic means 83 for operating the rising and falling quantity of the tray 16 according to the filing quantity on the basis of the detection result; and a driving part control means 17a for controlling the driving part 17 on the basis of the operation result. For example, the filing quantity detecting means 62 is formed of a sensor 26 for detecting the sheets supplied to the filing unit 13, and a contour 82 for counting the detection frequency of the sensor 26 until one filing operation is completed.</p> |
