摘要： PROBLEM TO BE SOLVED: To realize an autoanalyzer, capable of reducing the amount of cleaning liquid consumed and shortening the cleaning time, while maintaining effective cleaning of a nozzle in the case of an autoanalyzer, using a bore hole type reagent container with a nozzle the contamination range of which becomes wide. SOLUTION: A control part 101 calculates the length of a portion of the nozzle having penetrated from a bore hole in the bore hole type reagent container 112, namely, an area 203 of contamination, and determines a position to which the nozzle has to be lowered in a cleaning mechanism 109, according to the calculated area 203 of contamination. By stopping the nozzle at the position, only the area 203 of contamination is cleaned effectively in the mechanism 109, and the portions other than the area of contamination are prevented from being cleaned. Accordingly, an autoanalyzer can be realized, capable of reducing the amount of cleaning liquid consumed and shortening cleaning time, while maintaining effective cleaning of a nozzle in the case of an autoanalyzer using a bore hole type reagent container, with a nozzle with widening contamination range.

摘要： PROBLEM TO BE SOLVED: To provide an autoanalyzer with both a control means so as to observe the amount of a reagent to be discharged from a regent pump inside a movable-type reagent supplying part of the autoanalyzer and to discharge a necessary amount of a reagent at all times and a means for notifying an operator of anomalies in the reagent pump. SOLUTION: This autoanalyzer is provided with both a light source for detecting reagents at a reagent pump discharging part inside a movable-type reagent supplying part and a light detecting part for receiving light from the light source. As it is possible to measure the amount of a reagent liquid to be discharged from a reagent feeding means and to have a necessary amount of a reagent discharged at all times, it is possible to improve reliability in device data.

摘要： PROBLEM TO BE SOLVED: To provide a chemical analyzer capable of more efficiently agitating/ mixing a sample with a reagent and completely preventing their carry-over. SOLUTION: This chemical analyzer is provided with piezoelectric elements 205, 206 each forming a split electrode and emitting sound wave toward a reaction vessel 201 so as to cover a liquid surface 208 in its progressing direction and on its extension and so that the sound wave has a component coming into the liquid surface in parallel thereto or at an angle thereto. This causes a liquid portion adjoining the liquid surface to flow efficiently, thus agitating/ mixing the agitated materials in a noncontacting manner.

摘要： PROBLEM TO BE SOLVED: To provide an agitator that can improve the agitating efficiency. SOLUTION: This agitator has a structure in which the acoustic emission pressures by the sound waves from a sound source 9 that emits a sound wave 71a directing from the liquid phase 3 of a container 5 holding a liquid 3 to the gas phase 74 through the liquid surface 69 of a liquid in a quiescent state and from a sound source 7 that emits a sound wave 71b in the direction toward the gas phase 74 through the raised part of the liquid surface 73 raised by the sound source 9 are allowed to act respectively on the liquid surfaces 69 and 73, and a driver driving the sources 7 and 9 periodically changes the intensity of the sound wave from the source 7. According to this structure, the agitator can generate a pulsating swirl capable of giving an agitation efficiency higher than that by a swirl in a steady flow state and can therefore improve the agitation efficiency.

摘要： PROBLEM TO BE SOLVED: To realize an automatic analyzer capable of measuring accurate absorbance even if ultrasonic intensity becomes excessive due to the agitation of a specimen and a reagent or the like. SOLUTION: A plurality of reaction containers 8 are arranged in the state of the side wall parts inclining at about 45 deg. without being orthogonal to two intersecting lines 20 orthogonal to each other while dividing a reaction disc 15 in four parts from the upper face side view. In this layout relation, each reaction container 8 can have an ultrasonic irradiation face 22 almost orthogonal to the applied ultrasonic wave, and an absorbance measuring face 21 almost orthogonal to applied measuring light. The ultrasonic irradiation face 22 and absorbance measuring face 21 are made different faces and to constitute the absorbance measuring face 21 not to be irradiated with ultrasonic wave. Consequently, even if the ultrasonic wave applied on the irradiation face 22 becomes excessive to deform the ultrasonic irradiation face 22, the absorbance measuring face 21 is not irradiated with ultrasonic wave, so that deformation caused by ultrasonic wave can be avoided.
