Abstract: A remaining amount detector measures beforehand a distance H where there is one sheet. A motor displaces a lifting plate to a paper-feeding position upon storing paper in the feeding unit. The remaining amount detector measures a distance y1 to the lower face of a paper stack. Thereafter, upon transport of paper from the stack, a control unit causes the remaining amount detector to measure a distance y2 for every predetermined number n of fed sheets. A remaining sheet calculation unit calculates a displacement y1?y2=?y to the bottom of the paper stack S, and calculates the thickness of one sheet on the basis of the displacement ?y and the number n of fed sheets (t=?y/n). The remaining sheet calculation unit divides the thickness (H?y2) of the paper stack by the thickness t of one paper sheet, and calculates the number of remaining sheets m as (m=((H?y2)/t)+1).
