Abstract

A sheet supply apparatus according to the present invention has a pawl separator for separating sheets one by one by regulating the tip ends and upper surfaces of tip end portions of the sheets, which pawl separator can be retarded from a sheet regulating position when it is urged by the sheet with a predetermined force. With this arrangement, sheets having small resiliency such as plain sheets are separated one by one by successively riding over the pawl separator, and sheets having great resiliency such as post cards and envelopes urge the pawl separator to a retracted position to pass through the pawl separator and are separated one by one by of another separation.
