Abstract
A sheet feeding apparatus comprises a pressure plate disposed at a position where sheets first hit the same and a separation plate for separating the sheets. The pressure plate and the separation plate are rotatable independently of each other. The pressure plate is pressed by one spring, while the separation plate is pressed by another spring, against sheet feed roller independently of each other.

A sheet feeding apparatus comprising:
- (a) a chassis;
- (b) a base provided at a portion of said chassis;
- (c) a sheet feed roller mounted on said chassis;
- (d) a pressure plate having a forward end engaged with said base and having a backward end at a position where the backward end is capable of contacting said sheet feed roller;
- (e) a first resilient member fixed to said base for pressing the backward end of said pressure plate against said sheet feed roller;
- (f) separation plate disposed next to the backward end of said pressure plate and forwardly thereof with respect to rotating direction of said sheet feed roller;
- and
- (g) a second resilient member fixed to said base for pressing said separation plate against said sheet feed roller;
- and
- wherein the backward end of the pressure plate includes a separate pressure portion rotatable between first and second position relative to the sheet feed roller and the separation plate responsive to a force from a plurality of sheets.
