摘要： A document feeder (10) for a copier (16) in which documents (17) are conveyed over the platen (14) of the copier to a registration position (18). A belt transport system (12) is used which has a plurality of spaced belts (30) engaging the document vertically retractable registration fingers (22) extend between the individual belts into the document transport path providing an abutment for the entering document. The registration fingers are deflectable in the direction of sheet mvement in order to absorb the kinetic enegy of the entering document. The fingers are also spring loaded by elongate buckling leaf springs (82) which act to restore the registration finger and the document upstream to the correct registration position. With this configuration the leading edge of documents is less prone to damage even at relatively high transport speeds, e.g. > 200 cms⁻¹.
