Conveying mechanism and printing device

The invention provides a conveying mechanism and a printing device. The conveying mechanism comprises a conveying channel and a roller, wherein the conveying channel comprises channel plates; a clearance is reserved between the roller and the channel plates; part of the roller is located in the conveying channel; the conveying mechanism further comprises a detection plate and a sensor; the detection plate and the roller are located on the same side of the conveying channel, and are oppositely arranged at an interval; and the detection plate is used for moving to trigger the sensor when a printing medium is stuffed between the detection plate and the roller. Compared with the prior art, the conveying mechanism and the printing device can immediately detect a paper stuffing problem, prevent equipment failures caused by the reason that the printing medium is wound on the roller, and therefore, are high in reliability. 本发明提供了种输送机构和打印装置。其中，所述输送机构包括输送通道和辊轮，所述输送通道包括通道板，所述辊轮与所述通道板之间存在缝隙，且所述辊轮的部分位于所述输送通道中，所述输送机构还包括检测板
