Abstract
A paper feeding apparatus for a printing apparatus includes a pickup roller, which rotates in close contact with a sheet of paper loaded in a cassette and which allows the paper to enter in a paper feeding path of the printing apparatus, and a moving device, which allows the pickup roller to be selectively close to or separated from the paper loaded in the cassette while moving the pickup roller up and down. The moving device includes a rotary shaft connected to a predetermined driving source, a pivoting member, installed at the rotary shaft to be capable of pivoting, and having the pickup roller rotatably supported at a free end thereof, a slider, sliding in engagement with the cassette entering in the printing apparatus and having a predetermined cam portion for pivoting the pivoting member formed at one side thereof, and an engagement rib provided at the pivoting member to be capable of sliding along the cam portion of the slider, wherein, when the slider is moved as the cassette enters or is pulled from the printing apparatus, the engagement rib slides along the cam portion to pivot the pivoting member so that the pickup roller is moved up and down. Thus, as the pickup roller is allowed to contact the paper after the cassette completely enters the printing apparatus, the displacement of the position of the paper can be prevented when the cassette is inserted.
