Abstract:
A sheet feeding unit has a main body, a sheet stack portion attached to the main body to accommodate a stack of sheets, a sheet feeding device disposed substantially above the sheet stack portion to feed the sheet onward, which is movable between a sheet feeding position at which the sheet feeding device contacts the sheet and feeds the sheet onward and a separating position at which the sheet feeding device separates from the sheet and does not feed the sheet onward, a separation unit to separate the sheets, a restriction member disposed between the sheet feeding device and the separation unit and is switchable between a sheet feeding state when the sheet feeding device is at the sheet feeding position and a sheet restriction state when the sheet feeding device is at the separation position, and a cover openably closable relative to the main body and constituted as an independent member.
