Claims

[Scope of utility model registration request]

The printing paper to be inserted is guided by a deflector, and a spring-biased feed roller is pressed against the platen through a roller window provided with the deflector, and the platen is rotated to pass the printing paper between the feed roller and the planar. In a paper feeding mechanism of a printing device that feeds paper across the paper, the feed roller is rotatably attached to the roller shaft, and the feed roller inserted into one of the roller windows is divided into a plurality of parts. Paper feed mechanism of printing device.
