Method for detecting samples

摘要

A method for detecting samples by comparing outputs corresponding to a carrier portion free from sample with those corresponding to a carrier portion onto which a sample is applied while detecting said outputs with a plural number of sample detectors arranged in the direction perpendicular to the shifting direction of a carrier, selecting a sample detector showing the highest output reduction ratio as the one to be utilized for sample detection and detecting the end edge of a sample as a time at which output of said sample detector changes from a level darker than a preset value to another level brighter than said preset value.
