发明名称 Paper supply apparatus
摘要 This invention provides a bottom removal-type paper supply apparatus used in an image reading apparatus or the like which can always accurately supply paper into the image reading apparatus regardless of whether the amount of paper stacked on a paper support base is small or large.
