Abstract
An automatic biasing mechanism for a paper cassette support plate for use in an electrophotographic copier in which a removable paper cassette is provided with a plate upon which a supply of copy sheets is placed. A feed roller assembly within the copier is adapted to remove the uppermost sheets of paper from the cassette and activate a sensor when the top of the stack of sheets falls below a predetermined level. The sensor provides an output energizing a motor to rotate a shaft having a roller adapted to pivot the plate to move the stack of sheets to a position at which the uppermost sheet engages the feed roller assembly. The shaft, normally biased so as not to be in driven engagement with the motor, is moved into operative relationship with the motor by the cassette upon its insertion in the copier.
