A sheet processing apparatus includes: a buffer unit which stores plural supplied sheets with upstream edges in a conveying direction thereof aligned; a processing tray on which sheets discharged from the buffer unit are stacked; and an oscillation roller pair and a return roller which convey the sheet stacked on the processing tray to bring the sheet into abutment against a stopper for receiving the upstream edge of the sheet. The buffer unit is adapted to align the upstream edges of only sheets to be stored before a sheet to be supplied last among the sheets to be stored.

A filter press for filtering a slurry in which there are a plurality of filter frames movable toward and away from each other and in which at least one movable pressure plate is positioned between each pair of filter frames. The pressure plate and filter frames form a filter chamber on each side of the pressure plate. This pressure plate is a combination of a partition plate positioned between the filter frames and frame members on opposite sides of the partition plate adjacent the filter frames. The frame members and filter frames have an open space thereinbetween which defines the filter chamber. The pressure plate also has a plurality of diaphragm members, one member on each side of the partition plate between the frame member and the partition plate. The diaphragm members and the partition plate have interstices thereinbetween. Further provided are a slurry nozzle inserted into the filter chamber for directing slurry thereinto and a slurry feed supply connected to the nozzle which supplies slurry thereto at a predetermined pressure. A water supply source provides compressed water at a predetermined pressure and is connected to the interstices between the diaphragm member and the partition plate. A pressure adjustment device is connected between the slurry supply and the compressed water supply in order to maintain pressure of the compressed water provided to the interstices at a pressure lower than the pressure of the slurry supplied into the filter chamber.
