摘要： A feeding roller structure includes a fastening frame, a transmission component, a transmission roller and a floating coupler. The transmission component is assembled in the fastening frame. The transmission component includes a drive shaft transversely pivoted to two sides of the fastening frame. The transmission roller is concentrically arranged around the drive shaft. The floating coupler is mounted to the fastening frame. The floating coupler is coupled between the drive shaft and the transmission roller. Two opposite ends of the floating coupler are adjacent to and spaced from the two sides of the fastening frame to form two gaps. Each gap is formed between one end of the floating coupler and one side of the fastening frame. The two gaps limit an angular displacement of the floating coupler.

摘要： A paper feeding mechanism includes a mechanical frame, a gear assembly, a paper supply tray, a pickup assembly, a paper pressing assembly and a stopper assembly. The gear assembly includes a drive gear and a transmission gear. The paper pressing assembly includes a paper pressing frame, a paper pressing tray, a gear shaft, at least one swing arm and an elastic element. The stopper assembly includes a blocking element and a connecting element. The drive gear drives the transmission gear and the gear shaft to rotate, the connecting element drives the blocking element to move downward to make the blocking element realize a paper blocking function, and the drive gear breaks away from the drive gear, the elastic element pushes against the paper pressing tray to move downward, the blocking element breaks away from the paper supply tray to raise up for making the paper blocking function disappeared.
