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.

[ What is claimed is:] [1.] An automatic sample treatment apparatus for vials, comprising:a tray for holding a plurality of vials, said tray having vial position markers corresponding to positions where the vials are located and a home position marker for indicating a home position of the tray, said home position marker being different in shape from the vial position markers and located on the tray at a horizontal level same as that of the vial position markers,driving means connected to the tray for moving the tray and stopping the tray at a sample treatment position and a home position,position detecting means situated near the tray for detecting the vial position markers and the home position marker on the tray,vial detecting means situated near the tray for detecting a vial when the tray is stopped at the sample treatment position,a syringe disposed above the tray, andcontrol means connected to the syringe, the position detecting means, the driving means and the vial detecting means, said control means controlling the driving means and the syringe such that the tray is moved and stopped at the home position by actuating the driving means while the home position of the tray is being detected by the position detecting means; when a vial on the tray located at a predetermined position is moved to the sample treatment position, the tray is moved and stopped by the driving means while a number of the vial position markers to the predetermined position is being counted by the position detecting means; and then if the vial detecting means detects the vial at the predetermined position, the syringe is actuated.
