Abstract:
1. A sheet feeding apparatus, comprising: a sheet feeding mechanism configured to feed a sheet; a sheet sensor configured to detect, as a detection value, a physical quantity related to the sheet fed by the feeding mechanism; a physical-quantity judgment section configured to judge whether the detection value detected by the sheet sensor falls within a predetermined range; an another-sheet judgment section configured to judge whether there is another sheet after a sheet fed by the feeding mechanism and to be judged by the physical-quantity judgment section, said another sheet being a sheet different from the sheet fed by the feeding mechanism; a double-feeding judgment section configured to judge that double feeding has occurred when the physical-quantity judgment section judges that the detection value does not fall within the predetermined range and when the another-sheet judgment section judges that there is another sheet, the double-feeding judgment section being configured to judge that the double feeding has not occurred when the physical-quantity judgment section judges that the detection value does not fall within the predetermined range and when the another-sheet judgment section judges that there is no another sheet; and a command acceptance section configured to accept a judgment inhibition command for inhibiting the double-feeding judgment section from judging whether the double feeding has occurred, wherein, when the command acceptance section has accepted the judgment inhibition command, the double-feeding judgment section does not execute the judgment whether the double feeding has occurred, regardless of the judgments of the physical-quantity judgment section and the another-sheet judgment section.
