する紙送り機構。 A cylindrical paper feed roller to which a driven pulley is coaxially fixed is rotatably disposed, a drive belt is provided stretched between the driven pulley and a drive pulley rotationally driven by a drive motor, In the paper feeding mechanism, the paper feeding mechanism rotates the paper feeding roller via the drive belt by driving the drive motor, and sends the paper fed to the paper feeding roller portion to the printing section at a predetermined paper feeding pitch. The radius of the outer circumferential surface of the portion of the belt wound around the driven pulley is formed to be the same as the radius of the outer circumferential surface of the paper feed roller, and detection markers are provided at a constant pitch on the surface of the drive belt. A paper feeding mechanism comprising a detection sensor that reads a detection marker on the drive belt and detects the amount of movement of the drive belt.
