Abstract

PURPOSE:To detect the color of an object to be measured with small space and a low cost by disposing respective optical fibers to the end faces of photoconductive fiber bundles, converting the light past the respective optical fibers photoelectrically, and processing the outputs thereof. CONSTITUTION:The light information collected with a lens 21 is divided to small fiber bundles 25-27. The optical information conducted by the bundles 25-27 is conducted through optical connectors 28-30 and further through optical fibers 32-34 to photoelectric transducers 25-27. The weak signals from the transducers 25-27 are transmitted through preamplifiers 38-40 and an input- output connector 41 to a decision device.
