ABSTRACT:
An automatic sampler of the invention holds a sample properly. The automatic sampler is formed of a sample holding section, and a moving mechanism attached to the sample holding section. The moving mechanism moves the sample holding section in plural directions to transfer the sample held by the sample holding section. The sample holding section has a holding mechanism, and at least three fingers projecting downwardly from the holding mechanism. When the holding mechanism is actuated, a space defined among the fingers is regulated to hold the sample by the fingers. Each finger has an elongated circular member with an elastic portion at least at an outer surface thereof, and is freely rotatably attached to the holding mechanism. Thus, when the sample is held by the fingers, the fingers are properly located on the sample to surely hold the sample.
