PURPOSE: To transport a molding sample for analysis to a specific analyzing device automatically, by mounting and demounting the molding sample for analysis on and from a holder at specific sample and conveying the holder to the specific analyzing device by a holder tray.

CONSTITUTION: The molding sample is transfer between a molding sample conveying device 3 and a molding sample mounting and demounting device 4 by a molding sample passing and receiving device 5. The molding sample is mounted on the demounted from the specific holder 15 by the molding sample mounting and demounting device 4 and the holder 15 after the mounting and demounting is mounted on and demounted from the holder tray 14. This holder tray 14 is conveyed to a specific place by the holder tray conveying device 6. A standard sample storage elevation device 7 for storing many kinds of standard samples is added to the holder tray conveying device 6 and standard samples are conveyed to the holder tray conveying device 6 if necessary.
