Abstract
A paper feeding apparatus for a printer, comprising feed rollers to feed sheets of paper in a direction across a line of printing, a paper stacker holding the sheets in a stack and movable between an advanced and a retracted position, a biasing device for biasing the paper stacker toward its advanced position to urge a top sheet of the paper stack into contact with the feed rollers, a manually operated member movable between a first and a second position, a retract-and-latch device for moving the paper stacker to the retracted position against a biasing force of the biasing device and locking the paper stacker at the retracted position when the manually operated member is moved from the first to the second position, and an unlatch device for releasing the retract-and-latch device to allow the paper stacker to return to the advanced position when the manually operated member is moved toward its first position. Also disclosed is a pressure adjusting device for adjusting the biasing force of the biasing device depending upon a specific kind of the sheets on the paper stacker.
