OUTPUT MECHANISM, PRINTING DEVICE, AND TERMINAL DEVICE

摘要

A paper discharge mechanism (3) and a printing device (2) and a terminal equipment having the paper discharge mechanism are disclosed. The paper discharge mechanism comprises: a first side passage plate (33) and a second side passage plate between which an S-shaped paper conveying passage is formed, wherein the second side passage plate comprises a paper jam detection plate (321) and a paper pullout detection plate (311) both pivotally connected on a frame; a first elastic element (322) biasing the paper jam detection plate toward the first side passage plate and a second elastic element (312) biasing the paper pullout detection plate toward the first side passage plate; and a first sensor (324) for detecting the position of the paper jam detection plate and a second sensor (314) for detecting the position of the paper pullout detection plate. A surface of the paper jam detection plate facing paper (R) is concave and is held against the paper and rotates in the direction away from the first side passage plate during paper jam; a surface of the paper pullout detection plate facing the paper is convex and is held against the paper and rotates in the direction away from the first side passage plate during paper pullout. The paper discharge mechanism is capable of preventing a user from interfering with paper output and also enhancing the reliability of paper conveyance.
