Claim:
A paper cartridge for a printing apparatus to print on paper, comprising: a cartridge body; a pressure plate to move upward and downward in the cartridge body, the paper being stacked thereon; a pick-up roller to pick up the paper stacked on the pressure plate; a spring to elastically bias the pressure plate toward the pick-up roller; a claw unit to support a front end of the paper stacked on the pressure plate and to separate the paper picked up by the pick-up roller sheet by sheet; a cover member pivotably disposed at the cartridge body to cover the paper stacked on the pressure plate, to prevent the paper from being contaminated with a foreign material; an association movement unit through which the cover member and the claw unit are moved in association with each other, the association movement unit to separate the pressure plate from the claw unit to allow the paper to be stacked on the pressure plate; and an automatic driving unit to automatically close the cover member when the pick-up roller is driven with the cover member being opened, to thereby return the pressure plate and the claw unit together.
