<P>PROBLEM TO BE SOLVED: To provide a population counting device capable of highly accurately counting a population of organisms even for such a microscopic individual organism as a prawn larva, reducing a risk of debilitating or annihilating the organisms, and being miniaturized due to a simple structure. <P>SOLUTION: A population counting device has inclined channels 10A and 10B which are inclined in predetermined directions so that an individual organism to be counted flows with liquid. Aggregation of the organisms to be counted is poured in the population counting device. The poured organisms are dispersed while being transported in the inclined channels 10A and 10B. In a counting section 18B provided in a middle of the inclined channel 10B, the dispersed organisms are counted in a manner that photographs the same by a camera 40 and analyzes a photographed image by an image analysis section 50. An illumination mechanism 30 is arranged on a rear surface side of the counting section 18B through a diffuser panel so that the illumination mechanism 30 orthogonally irradiates the counting section 18B with white diffusion light for enabling the counting section 18B to photograph the image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
