Abstract
A sheet feeder for feeding a single sheet from a stack of sheets by using a rotating cylindrical feed roller having a truncatel portion spaced away from the stack and a full diameter portion able to contact the stack whenever it is lifted by a lifting arm, which is pivoting in a timed relationship to the feed roller. This device simplifies sheet timing and eliminates the need for a constant biasing of the stack against a feeding member.
