A sheet loading unit includes a main body, a sheet loading plate, a pair of positioning portions, a pair of racks, and a pinion. The sheet loading plate is disposed on an upper surface of the main body. The racks are connected to the positioning portions. The pinion engages with the pair of racks so that the positioning portions move in an interlocking manner. At least one of the racks includes a stopper capable of moving between a first position facing a lower surface of the pinion and a second position not facing the lower surface of the pinion when the rack moves along the width direction. |
