SAMPLE DETECTOR AND MEASUREMENT DEVICE EQUIPPED WITH THE SAME

摘要

A sample detector (B) has a member (6) provided with an aperture (60) in addition to a light receiving element (5) which outputs a signal corresponding to the amount of two light beams received which are emitted from a pair of light sources (40, 41) to a detection area (AR) and transmitted through the detection area (AR) and a judgment means (8) which judges whether a sample is properly supplied to the detection area (AR) on the basis of the signal.The two light beams emitted from the pair of light sources (40, 41) advance along courses regulated by the aperture (60) to areas (ARr, ARf) deviated from each other in the detection area (AR).Therefore, it is possible to precisely judge whether the sample is supplied to the detection area (AR) without using an expensive component such as an optical lens.
