Paper feed-out clipping roller with protuberances for preventing ink smearing in a printing apparatus

摘要

A printer has a housing and a recording apparatus set in the housing for printing information on a recording media. The recording apparatus has a paper feed-out roller in the housing for driving the recording media, and a set of paper feed-out clipping rollers set on one side of the paper feed-out roller for clipping the printing media between the paper feed-out clipping roller and the paper feed-out roller for driving the recording media out of the housing. The paper feed-out clipping roller has a circular circumference and a plurality of protuberances on the circumference surface. When the paper feed-out clipping rollers and the paper feed-out roller are driving the recording media forward, the circular circumferences of the paper feed-out clipping rollers will not completely contact the recording media and so will not cause ink smearing.
