ABSTRACT:
A paper storage device comprises a sensor for generating a detection signal indicative of the arrival of a top level of a stack of papers on a paper support tray at a predetermined height so that the paper support tray can be lowered in response to the detection signal, and a counter for counting the number of papers successively stacked on the paper support tray so that an indication that the paper support tray is held at an improper position can be provided when the counter counts a predetermined number of the papers during the absence of the detection signal from the sensor. Once the top level of the paper stack on the paper support tray has attained the uppermost limit position, the top level of the paper stack on the paper support tray is lowered to a lowermost limit position to secure the orderly disposition.
