Title:
自動分析装置
Document Type and Number:
Japanese Patent JP6931724
Kind Code:
B2
Abstract:
There is provided an automatic analysis device which can properly control an operation of a dispensing nozzle by identifying a target with which the dispensing nozzle comes into contact, and which can avoid damage to the dispensing nozzle. In a case where a sample container 15 has a rubber-made lid 35, if a sample nozzle 12a descends and comes into contact with the lid 35, the sample nozzle 12a is relatively moved inside an arm 42 as far as a lid detection distance 48, and a detector 44 detects a detection plate 43. A fact that the sample nozzle 12a comes into contact with the lid 35 is stored together with position information of the sample nozzle 12a, into an operation commanding unit. The sample nozzle 12a further continues to descend, and a suction operation of a sample 34 is performed at a predetermined position. In a case where the sample nozzle 12a collides with a frame portion 36 of the lid 35 and external force is applied thereto, the detector 44 detects that the detection plate 43 is relatively moved as far as the detection distance 48. Thereafter, the sample nozzle 12a stops descending, when excessive external force is applied due to the sample nozzle 12a trying to descend and the detection plate 43 is relatively moved as far as an obstacle detection distance 49.
