A sheet feed apparatus for a copying machine comprises a cassette for holding a stack of sheets to be fed. The cassette is in the form of an open-topped housing containing a base plate for supporting the stack of sheets. A handle is provided which is coupled to a mechanism for raising, preferably tilting, at least part of the base plate right out of the cassette housing to facilitate loading sheets within the tight tolerances of the cassette housing. A rear registration guide and a pair of relatively small side guides are provided which do not impede stack loading but allow the stack to be positioned sufficiently accurately that when the handle--and hence the base plate--is lowered the stack is able to enter the cassette housing without further adjustment.
Sheet feed apparatus for a copying machine comprising a cassette for holding a stack of sheets to be fed, wherein the cassette comprises an open-topped housing containing a base plate for supporting the stack of sheets, characterised by a manually operable actuator coupled to means for raising at least part of the base plate out of the cassette housing to facilitate loading sheets in the cassette, and wherein the actuator is movable between a first position in which the at least part of the base plate is in its operative position for sheet feeding, and a second position in which the at least part of the base plate is in its fully raised position for sheet loading.
