摘要： Sheet slitting apparatus which includes a plurality of belt members each having a clamp to receive the leading edge of a sheet to be slit. The clamps are urged downwardly by the action of guide members arranged in the belt path to grip the sheet securely during the slitting operation. The clamps are released after slitting is completed.

摘要： An improved document feeding system includes a flat perforated vacuum transport belt mounted to move one surface thereof across a scanning station, and a perforated document support plate for accurately placing a document on the belt. The plate is supported in a drawer, and the corner of the drawer and registration fingers serve to position the document on the support plate. After a document is positioned on the support plate, the drawer is slid to a position opposite the one surface of the belt, and then the support plate with the document thereon is moved to a position immediately adjacent that surface to position the document on the belt where the document is held via vacuum. The plate is then retracted into the drawer, and the belt with the document thereon is moved across the scanning station.
