Abstract

PURPOSE: To improve the printing quality of an optical printer by flatly regulating the wavelength sensitivity of a photosensitive body by the light emission output of a light source for exposing.
CONSTITUTION: The light output of an LED array 1 is applied to a filter 2 which varies in light transmittance with the wavelength of light and the light output after the transmission through the filter 2 is received by a solar battery 3. The current value flowing in the respective LEDs 1 from a current supplying device 5 is so controlled that the electromotive voltage of the solar battery 3, as measured by a voltmeter 4, attains the specified value. The individual outputs of the LED array 1 are mated with the spectral sensitivity characteristics of the photosensitive body, by which the printing density of the optical printer is maintained nearly constant.
