PURPOSE:To improve the safety and the operability of an analyzer by providing operation annunciating means on a sampling arm and reagent arms. CONSTITUTION:A sample is injected into a reaction tube 13 facing a position A under the state wherein the reacting tube is stopped. At this time, a CPU 18 sends a signal to a sampling-arm driving control part 20 in accordance with a predetermined program. A sampling arm 14a is turned to a sample cell 14c with a shaft 14b as a supporting point. The CPU 18a also sends a signal to a lamp 17a through a lamp driving control part 19 before the turning of the arm 14a. The lamp 17a is lighted, and the turning of the arm 14a is announced beforehand. Then, the arm 14a is lowered, and the sample is sucked out of the sample cell 14c. The CPU 18 sends a signal before the arm is lifted up again, and the lamp 17a is lighted. When the arm 14a is stopped on the reacting tube 13, a light-out signal is sent and the operation annunciation is finished. When first and second reagents are injected, lamps 17b and 17c are lighted by the same way. Thus, the operations of arms 15a and 16a are annunciated beforehand. |
