Claim:
A sheet loading apparatus comprising: a sheet loading unit having V-shaped cross-sectional grooves on which sheets are loaded; a position adjustment unit which is movable on the sheet loading unit and regulate a position of sheets stacked on the sheet loading unit; a fixation member which is rotatably fixed to the position adjustment unit and has a V-shaped rib for engaging with the V-shaped cross-sectional grooves of the sheet loading unit, the V-shaped rib being disposed on a lateral side opposite to the sheets loaded on the sheet loading unit so that a rotational axis of the fixation member is positioned between the V-shaped rib and the sheets loaded on the sheet loading unit relative to a moving direction of the position adjustment unit; and an operational portion disposed on a side of the fixation member facing the sheets between the rotational axis and the V-shaped rib for releasing connection between the V-shaped rib and the V-shaped cross-sectional grooves, wherein the position adjustment unit is movable along a first direction, and the rotational axis of the fixation member extends perpendicular to the first direction, wherein when a force is applied to the position adjustment unit in the first direction away from the sheets, the force acts on the fixation member to urge the V-shaped rib to one of the V-shaped cross-sectional grooves, and wherein the operational portion is configured to release connection between the V-shaped rib and the V-shaped cross-sectional grooves when the operational portion is pushed along the first direction away from the sheets.
