Abstract

PURPOSE:To prevent the occurrence of exhaustion of toner, power consumption and poor appearance of output originals, etc., at a receiver side even when some abnormalities occur in a light source. CONSTITUTION:When a light source becomes abnormal, the output of a monitoring element 6 installed near the light source 1 becomes a low level, and a changeover device 8 is switched to the other terminal side. Then, the output of a white signal generating circuit 7 is given to a modulator 5 through the changeover device 8. In this case, a white signal from the white signal generating circuit 7 is transmitted to a receiver. This operation is continued until the light source 1 is restored.
