ABSTRACT:
In a sheet feeding apparatus, a contact-type sensor for detecting sheet-like documents stored in document tray is separated into upper document detector and a lower document detector arranged at upper and lower sides of the document tray, respectively. The sheet-like documents are detected separately with two actuators of the corresponding detectors. Accordingly, the requirement of a prior art for having a contact of the sensor increased in length in order to detect the sheets from a maximum to zero in the sheet storing unit can be eliminated.
