A specimen identification device comprising: a specimen source providing a specimen; a specimen introduction nozzle sucking a sample including the specimen which exists in the specimen source by contacting with the sample at a first end of the specimen introduction nozzle so that the sample is introduced to a second end of the specimen introduction nozzle; a flow path receiving the sample by inserting the second end to a part of the flow path and forming an appropriate flow of said sample to identify an identifier of said specimen; an identification portion including light receiving portions that detect said identifier as light information and is provided at a part of a circumference of said flow path; and a specimen dispensing device dispensing a specimen identified as a target specimen or a non-target specimen, wherein the identification portion identifies the specimen as the target specimen or non-target specimen based on the light information obtained by the light receiving portions, the specimen dispensing device comprises a dispensing nozzle (75, 375) for forming liquid droplets or liquid flow containing the specimen at its front end; a collecting container for collecting the liquid droplets or liquid flow containing the target specimen; a drain tank (69, 377) for collecting the liquid droplets or liquid flow containing the non-target specimen; and a moving means (61, 337, 353, 373, 397) for moving at least one of the collecting container, the drain tank (69, 377) or dispensing nozzle (75, 375), characterized in that an arrival time from the identifying portion to the front end of the dispensing nozzle (75, 375) is calculated based on the flow velocity of the specimen measured by the identification portion and a distance from the identification portion to the front end of the dispensing nozzle (75, 375), and based on the arrival time and a result of identifying the specimen, the specimen dispensing device lets the liquid droplets or liquid flow containing the specimen flow continuously from the dispensing nozzle (75, 375) to a liquid surface of the collecting container or drain tank (69, 377) so that the target specimen is dispensed to the collecting container while the non-target specimen is dispensed to the drain tank (69, 377), said light receiving portions are located in at least two or more different positions with respect to a traveling direction of the specimen, wherein said light receiving portions are optical fibers (31a, 31b), and the identification portion measures a flow velocity of the specimen based on time differences of the light information obtained by light receiving portions and a space between light receiving portions, wherein the light receiving portions are provided in such a manner that one part of each receiving portion is exposed to inside of the flow path. a specimen source providing a specimen;
