Claim:
1. A paper input mechanism having a buffer function, comprising a frame forming a conveying passage (P) for conveying continuous paper, and further comprising a fixed passage plate and a buffer plate both located at a paper inputting side of the conveying passage (P), wherein the buffer plate has an initial position and is pressed by the continuous paper to deviate from the initial position; wherein the buffer plate is opposite to the fixed passage plate when being located at the initial position, so as to form a paper input passage (R) and the paper input passage (R) is connected with the conveying passage (P), wherein the buffer plate is moveably connected with the frame, wherein the frame is provided with an elastic resetting element enabling the butter plate to reset to the initial position, wherein pairs of first and second guide pillars are respectively provided at two sides of the buffer plate along a conveying direction of the continuous paper, wherein the frame is provided with a first guide slot matched with the first guide pillar and a second guide slot matched with the second guide pillar, and wherein, during a process in which the buffer plate deviates from the initial position, the first guide pillar slides from a start end of the first guide slot to a stop end of the first guide slot and the second guide pillar slides from a start end of the second guide slot to a stop end of the second guide slot.
