Abstract
PURPOSE: To obtain an adequate original signal by taking sample hold by a timing signal by scanning an original by laser beam light generated by the timing signal and removing an influence of external light incident to the original when the scan output is converted into an electric signal and outputted.
CONSTITUTION: Beam l0 from laser light source 10 is transformed into beam light l2 to scan optical scale 15 for timing signal generation by way of mirrors 11, 13 and 14, etd. This optical scale 15, having many bar marks on the transparent glass plate, permits timing light to pass through it. The timing light projected out of scale 15 strikes photodetector 20 by way of mirror 19 to obtain a timing signal. From original 29, an original read signal is generated by photoelectric converter 33 and amplified and the amplified signal is inputted to the sample holding circuit by way of the clamping circuit; and the timing signal is also inputted to the holding circuit, so that after a noise signal in the original read signal is removed, the signal will be outputted.
