PURPOSE:To measure automatically and quickly the concentration at many points with a simple constitution and operation, by providing a sending mechanism controlled by a detection output of a detection mechanism and a measuring head for measuring successively each measuring part of a sample in synchronization with said sending mechanism, for sending a sample stand to an arrangement direction of the successively arranged measuring part. CONSTITUTION:A prescribed position detecting hole 5 of a sample cassette 3 is made to detect by a prescribed position detecting part 10 provided to the prescribed position of a densitometer main body 6 at the time of movement. When the hole 5 is detected, a driving motor 9 is stopped by a control mechanism (not shown in the figure) and a push-pull solenoid 11 is excited and a measuring head 13 is lowered via a link 12. Further, a measuring part 1 at the position corresponding to the detected hole 5 is made to measure by the head 13. After the measurement is performed, the solenoid is de-excited and the head 13 is raised. Then, the motor 9 is driven again and the cassette 3 is transferred to the next measuring position and so forth the same operation is repeated. |
