Abstract

PURPOSE:To avoid the dispersion in scanning speed of drive section, by emitting light from the light source to the linear encoder at the side of original platen, receiving the black-and-white signal at the photodiode and flowing the signal to the control for uniformity. CONSTITUTION:The rays emitted from the light source 1 are reflected at the reflection plate to emit the original 3' on the original platen 3, and the reflection light is received at the converging light transmission body to collect it on the photodetection array provided on the glass substrate 5. At the side of the original 3', the linear encoder 7 of reflection type is provided, where the reflection light 10 of the encoder 7 is read in for the speed control of the drive section. The photodetector 6 to read in the reflection light is provided aside the photodetection array located on the glass substrate 5.
