PURPOSE:To equip an optical analyzer with an inexpensive synchronizing-signal detecting method by providing one sensor that detects all synchronizing signals for sampling. CONSTITUTION:Synchronizing signal Sr (for reference-wavelength light signal sampling) generation part 35R, synchronizing signal Sm (for measured-wavelength light signal sampling) generation part 35M and synchronizing signal Sb (for lightocclusion signal sampling) generation part 35B are arranged at the same distance from the center of sector 10 and they are detected in series by one sensor. Synchronizing signals Sr, Sm and Sb detected by the sensor in series are input to input terminal (i) of shift register 51 in series and distributed to respective output terminals SR, SB and SM before being led out in parallel. Therefore, the sensor part can be made inexpensive since all synchronizing signals can be detected by one sensor. |
