Claims

[Scope of utility model registration request]

An original illumination light source in which light emitting elements are arranged in an array at a fixed pitch, and an imaging element in which light emitting elements are arranged in the same direction as the light emitting element array. In a facsimile reading device having an image element array, document illumination light sources are disposed in pairs on both sides of the image forming element array, and the light emitting element arrays are shifted by 172 pinches from each other, and In order to offset the brightness unevenness of the light emitting element array and the brightness unevenness of the imaging element array, the brightness distribution of each light emitting element is located at the position where the brightness distribution is the minimum with respect to the optical axis where the brightness distribution is the maximum. A reading device for Funakushimiri, characterized in that the optical axes of the imaging elements having the maximum brightness distribution substantially coincide with each other.
