PURPOSE:To properly record even accompanying information by detecting the quantity of light from an exposure means for exposing an original and controlling the quantity of light of a light emitting element array according to the detected value. CONSTITUTION:The quantity of light from the original exposure lamp 11 is detected by a light quantity detection sensor 7 to control the quantity of light of the light emitting element array 32. Namely, the detection signal of the sensor 7 is outputted to a microcomputer 15 through a light quantity measuring circuit 8 and an A/D converting circuit 9 and processed by the microcomputer 15. A light emitting element control circuit 33 is controlled according to the processing result to perform control over the quantity of light of the light emitting element array 32. |
