PHOTOSENSOR, PHOTOMETRIC MECHANISM FOR TEST IMPLEMENT, AND ANALYZER EQUIPPED WITH THE PHOTOMETRIC MECHANISM

摘要

PROBLEM TO BE SOLVED: To downsize a photosensor applicable to a photometric mechanism, and to downsize an analyzer and a photometric mechanism for this analyzer.;SOLUTION: The photosensor 8 is equipped with one or a plurality of light emitting parts 80 for irradiating an object 7 with light and one or a plurality of light receiving parts 81 for receiving reflection light from the object 7. The light emitting parts 80 and the receiving parts 81 are disposed so that an emission center axis L3 of the light emitting parts 80 and a light receiving center axis L4 of the receiving parts 81 are parallel or substantially parallel with each other. Preferably, the photosensor 8 is equipped with a light guiding means 82 for defining a light progressing path for at least one light beam out of a light beam going from the light emitting parts 80 to the object 7 and a light beam going from the object 7 to the receiving parts 81.;COPYRIGHT: (C)2004,JPO
