Abstract

The paper feeding device includes: a paper feeding cassette having side guides defining and setting the lateral size of the paper, a rear guide defining and setting the longitudinal size of the paper, and first and second loading parts simultaneously or separately receiving the paper ; The first lifting unit is installed on the paper feeding box to lift the first loading part; the second lifting unit is installed on the paper feeding box to lift the second loading part; the paper feeding unit, when the first loading part is lifted picking up and feeding the paper loaded on the first loading section one by one; a paper transfer unit installed in the paper feeding cassette to transfer the paper loaded on the second loading section to the first loading section; and A sheet detection unit that determines whether each of the first and second loading sections is loaded with sheets and whether sheets are simultaneously loaded on the first and second loading sections in a common manner.

Description

technical field [0001] The present invention relates to an image forming apparatus, and more particularly, to a paper feeding device used in the image forming apparatus and a paper feeding method thereof. Background technique [0002] In general, image forming apparatuses such as printers, copiers, facsimile machines, and multifunction products are equipped with paper feed cassettes for accommodating a stack of printable media such as paper used in image forming. The paper feed cassette is detachably or slidably installed in the main body of the image forming apparatus so that the paper feed cassette can be fully or partially exposed to the main body when new paper is placed therein or paper accommodated in the cassette is replaced with new paper external. [0003] The paper feeding box can be divided into a single-size box and a general-purpose box. The single-size box can only load paper of one size, and the general-purpose box can load paper of various sizes and can be a...
