Of course, in other embodiments, the height difference between the outer side surface of the first plate guide rail 5115 and the outer side surface of the first plate guide rail three 5113 may be set to be the same, or the height difference between the outer side surface of the second plate guide rail 5215 and the outer side surface of the second plate guide rail three 5213 may be set to be the same, and a certain anti-jamming effect may be provided, and in another embodiment, only one of the height differences between the outer side surface of the first plate guide rail 5115 and the upper portion and the lower portion of the outer side surface of the first plate guide rail three 5113 may be set to be gradually smaller from the middle portion thereof, or only one of the height differences between the outer side surface of the second plate guide rail 5215 and the upper portion and the lower portion of the outer side surface of the second plate guide rail three 5213 may be set to be gradually smaller from the middle portion thereof, and a certain anti-jamming effect may be provided.

As shown in fig. 6 to 7, as a first embodiment of the present invention, the plate-guide rib 5115 is disposed on the plate-guide three 5113 on a side close to the guide roller channel one 5114, compared to the plate-guide rib 5115 disposed in the middle area of the plate-guide three 5113, such that the outer side surface of the guide roller one 541 is adjacent to the outer side surface of the plate-guide three 5115 rather than the outer side surface of the plate-guide three 5113, since the height difference between the guide roller one 541 and the outer side surface of the plate-guide rib 5115 is relatively small, the roll paper is not easily jammed into the gap between the guide roller one 541 and the plate-guide rib 5115, thereby causing paper jam, and further preventing paper jam. Similar to the first paper guide 511, the second guide rib 5215 is disposed on the second guide third 5213 on a side close to the second guide channel 5214, compared with the second guide rib 5215 disposed in the middle area of the second guide third 5213, so that the outer side surface of the second guide wheel 551 is adjacent to the outer side surface of the second guide rib 5215 rather than the outer side surface of the second guide third 5213, and since the height difference between the second guide wheel 551 and the outer side surface of the second guide rib 5215 is relatively small, the roll paper is not easily jammed in the gap between the second guide wheel 551 and the second guide rib 5215, which causes paper jam, and further prevents paper jam. Of course, in other embodiments, the plate-guide rib 5115 may be disposed in the middle area of the plate-guide rib three 5113, or the plate-guide rib 5215 may be disposed in the middle area of the plate-guide rib three 5213, and may also have a certain anti-jamming function.
