Abstract: PURPOSE:To compensate the illuminance on a photoreceptor by detecting the decrease of the quantity of light of a lighting lamp for an original down to the outside of a control range by lamp voltage or a photodetector and changing the lens aperture of an optical system for the degraded part. CONSTITUTION:When a detected value V1 becomes smaller than the preset light lower limit value V2 and an illuminance drop signal is generated during controlling operation by an exposure control circuit, the output of an amplifier Q2 rises to H. If at this time a lamp L is lighting and yet the decreasing signal is generated continuously for more than the timing time of a timer T2, it is regarded that the lamp or circuit has deteriorated, and a transistor Tr1 which is controlled to produce output by the deterioration detection is turned ON to wider an aperture 7 and restore and correct the quantity of light. The aperture is controlled by changing, for example, aperture area, with a step motor. More specifically, the deteriorated signal LL is converted into predetermined pulses, and said pulses are counted to change a plate 7 as specified.
