Abstract

PURPOSE:To obtain a necessary exposure effect using a light source of small capacity, by providing a reflector equipped with a slit, around the light source for irradiating an original, and making it rotate synchronously with a scanning mirror. CONSTITUTION:As for an original 4 on the platen 1, the same part is irradiated for exposure scanning by two sets of light sources 2 equipped with the reflector 3 which is controlled so that it is rotated synchronously with the scanning mirror 5 by providing the slit 3a. Owing to this constitution, the light source beam is used effectively, and it is possible to obtain the same exposure effect as use of the light source of large capacity, although the light source of small capacity is used. The power consumption is reduced and the heating value is lowered.
