<p>PURPOSE:To reduce weight by miniaturization of a line printer and to improve productivity thereof which corrects uniformly a distribution of light intensity in a main scan direction of a line head. CONSTITUTION:Memory means 39, 41 which preliminarily respectively store an error data roughly estimating a distribution of light intensity of a light emission element array, a variation data of a light converging characteristic of a lens array, and a relative positional data between the light emission element array and the lens array, are provided. A correction data is calculated from each data of such memory means 39-41, and light emission correcting means 17, 37, 38 uniforming the light intensity of the line head are provided.</p> |
