Abstract
A sheet feeder is adapted to feed sheets, received in a stack within a sheet cassette, one by one by a feed roller which rocks in response to a feed signal. The sheet feeder includes a detecting member for detecting the number of sheets left within the cassette, and means responsive to a signal from the detecting member for controlling the timing when the feed signal is produced. In this manner, an amount of flexure produced in the sheet being fed before it reaches resistor rollers is maintained constant.
