備する印字装置。[Claims for Utility Model Registration] An optical transmission rod that is formed in a cylindrical shape and transmits light from a light source that enters from at least one end surface in its axial direction, and that transmits light along the longitudinal direction of the circumferential surface of the optical transmission rod. Diffusion stripes formed with different widths and which diffusely reflect the light transmitted in the axial direction, and slits formed along the longitudinal direction and facing the circumferential surface on the almost opposite side of the area where the diffusion stripes are formed. has
In a light irradiation device equipped with a reflection case that surrounds the circumferential surface of the optical transmission rod, the width of the diffusion stripe is adjusted to the incident end side of the optical transmission rod so that the light distribution of the amount of light emitted from the slit can be selected. 1. A printing device equipped with a light irradiation device, characterized in that the amount of light emitted from the slit is made uniform by forming the slit to be wider and narrower at the center.
