Abstract

In an automatic sample treatment apparatus of the invention, a tray for vials is provided with slits for a home position and vial positions. The slits for the vial positions have shapes different from that of the slit for the home position. When the apparatus is used, a position detecting sensor detects a desired sample position, and a vial detecting sensor recognizes that the vial is disposed. Then, a syringe is lowered to suck a sample from a vial. Accordingly, even if a stepping motor becomes out of tune, the tray can be transferred to a position in which a needle is securely inserted into the vial.
