Abstract
Provided is a sheet feeder, which includes: a sheet placing table; a rotary body which is movable and sends out sheets; a sheet placement detection portion for detecting placement of sheets; an upper limit detection portion for detecting that the rotary body has reached an upper limit position; a transport detection portion for detecting transport of sheets; and a control part which rotates the rotary body so as to perform sheet feeding operation regardless of a detection state of the upper limit detection portion when sheets are set on the sheet placing table, determines that a non-feed jam has occurred when no sheet arriving is detected, and stops rotating the rotary body by determining that the sheet feeder is brought into a sheet feeding restriction state, when sheets are set again on the sheet placing table and the rotary body is detected to be in the upper limit position.
