Abstract
This invention relates to sheet feeding apparatus including a cassette for holding a stack of sheets. It is known to provide in the cassette a lip or spring extending into the space in front of the stack, so that when a suction feeder acts on the front sheet to swing it through an arc and introduces it leading end into the nip of a pair of rollers, the leading end is momentarily retarded by the lip of spring. This has the effect of reducing the number of double feeds. In the present invention, the degree to which the lip or spring extends into the space in front of the stack of sheets is adjusted as the cassette is inserted into the apparatus by a control device which is set in accordance with the required rate of feed of the sheets.
