Abstract
PURPOSE: To provide an apparatus capable of preventing shortage of paper sheets, by always detecting the residual amount of paper sheets and indicating it continuously or intermittently by use of a signal from the output unit.
CONSTITUTION: In stacking paper sheets 2 on stage 3, the stage 3 is located in its lowermost position. In this state, when a sheet setting switch is pushed, up-down counter 18 is set into its down-mode position and at the same time motor 5 is set into rotation, thereby raising stage 3 to a position where the uppermost portion of the stacked sheets 2 is detected by photo-sensors 9, 10. Here, the total rotational angle of motor 5 is detected by photo-sensor 8 together with timing disk 7 and counted by up-down counter 18. In response to the output of the counter 18, a predetermined output voltage is produced from a DA converter, and the residual amount of sheets is indicated at an indicating section continuously or intermittently.
