ABSTRACT:
The paper feeding apparatus includes a paper feeding cassette having a side guide part for defining and setting a lateral size of paper, a rear guide part for defining and setting a longitudinal size of paper, and a first and second load part for simultaneously or separately accommodating paper sheets; a first lifting unit installed to the paper feeding cassette for lifting the first load part; a second lifting unit installed to the paper feeding cassette for lifting the second load part; a paper feeding unit for picking up and feeding the paper sheets loaded on the first load part sheet by sheet when the first load part is lifted up; a paper transfer unit installed in the paper feeding cassette for transferring paper sheets loaded on the second load part to the first load part; and a paper detection unit for checking whether each of the first and second parts is loaded with paper sheets and whether paper sheets are loaded simultaneously on the first and second load parts in a shared manner. The first and second lifting units are controlled to lift at least one of the first and second load parts according to determination whether paper sheets are loaded simultaneously on the first and second load parts in a shared manner, and the paper transfer unit is controlled to transfer paper sheets on the second load part to the first load part according to determination whether each of first and second load parts is loaded with paper sheets.
