PURPOSE:To prevent the evaporation of water contained in the sample by means of a sample tray protection cover provided at the top position of the sample tray housing container having an opening at the bottom position thereof. CONSTITUTION:A vertically long sample housing container 10 having an opening 10b which is larger than the side of the sample tray 1 on the side wall in the lowest portion thereof is provided on the support base 11 with a piston mechanism 14. After the sample trays 1 are housed in layers into the sample housing container 10 from the upper end opening 10a, a flat protection cover 12 is inserted thereinto. Then, the piston mechanism 14 is driven to move the push bar leftward so that the lowest sample tray 1 is pushed to the sample placement position A from the opening 10b and then, the sample is put at the coating tip. This allows the sample tray 1 placed at the upper position and the protection cover to cut samples on the sample tray 1 off from open air awaiting the feeding thereby preventing the evaporation of water contained. |
