Abstract

PURPOSE:To improve the photometric efficiency by mounting a shutter in an openable manner in a photoelectric detector so that the light received by the detector prior to the measurements of the respective cells is blocked to eliminate the phenomena of residual images. CONSTITUTION:The light from its source 1 enters a spectrometer 12 through the sample cell of a cell unit which is intermittently moved transversely. The flux of light entering a recessed diffraction grating 2 from the incident slit 13 of the spectrometer 12 is subjected to spectroscopy and condensed so that it goes into a plurality of photoelectric converting elements 3 and is detected. Immediately in front thereof, a plurality of shutters 4 are provided. These shutters 4 are adapted to be opened, when the sample cells are to be measured, by a shutter driving mechanism 11 which is made operative in response to the signals from a control circuit 9. On the other hand, the unit 5 connected with the nunerous cells is moved by a cell driving mechanism 10. The singls to move the same are also generated from the circuit 9. Thus, the phorometric efficiency can be improved.
