PAPER FEEDING MECHANISM HAVING BUFFERING FUNCTION AND PRINTING DEVICE USING SAME

摘要

A paper feeding mechanism having a buffering function and a printing device using the mechanism. The paper feeding mechanism (300) comprises a frame (1) forming a conveying passageway (P) for conveying continuous paper, and further comprises a fixed passageway plate (4) and a buffer plate (2) both located at the paper feeding side of the conveying passageway (P), wherein the buffer plate (2) has an initial location and is deviated from the initial location under the pressing of the continuous paper; the buffer plate (2) is opposite to the fixed passageway plate (4) when being located at the initial location, so as to form a paper feeding passageway (R), and the paper feeding passageway (R) is connected with the conveying passageway (P). Arrangement of the buffer plate (2) not only gives the buffering function, but also results in close fit between the buffer plate (2) and the frame (1) of the paper feeding mechanism (300) to create an exclusive paper feeding port, thereby effectively avoiding the problem that continuous paper is incorrectly installed by users, and improving the usability of the product.
