ABSTRACT:
A sheet feed apparatus for use with a copying machine comprising a sheet stacking member for stacking recording sheets thereon, and a pair of sheet feed rollers for feeding the recording sheets one by one, which are arranged coaxially on a driving shaft disposed above the sheet stacking member, and one sheet feed roller is located at an appropriate position and the other sheet feed roller is movable along the driving shaft. The sheet stacking member can take two positions, a sheet feed position and a sheet replenishment position, by sliding the sheet stacking member in and out of the body of the copying machine. When the sheet stacking member is slid out of the body of the copying machine to the sheet replenishment position and recording sheets are stacked on the sheet stacking member and then slid into the body of the copying machine, the position of the movable sheet feed roller is automatically determined appropriately in accordance with a partition plate which is to be set in accordance with the size of the recording sheets.
