[Technical field to which the invention is applied] The present invention relates to an automatic chemical analyzer, in particular, which adds a reagent to a liquid sample to cause a chemical reaction, measures the coloring state of the sample, and detects the components or test items in the sample. The present invention relates to an automatic chemical analyzer for such analysis. [Background of the Invention] There are a variety of automatic chemical analyzers conventionally used in clinical tests, etc., ranging from large machines to small machines, depending on the number of specimens handled. Generally, large machines with high throughput are used in testing rooms of large hospitals or testing centers that specialize in testing, and small machines are used in small and medium-sized hospitals. Two methods can be considered in order to provide efficient automatic chemical analyzers that can be used over a wide range of systems, from large machines to small machines. One method is to provide separate devices that are optimally designed for each model. Another method is to unitize the functions of the equipment and cover a wide range of models by configuring these units. The former drawback requires a great deal of effort and cost for development and design, and may also leave problems with production equipment and production efficiency. The latter method is the opposite of the former and is an efficient method, but it often leaves operational problems because it is not an optimal design. For example, assume that the entire automatic chemical analyzer is divided into an analysis section and a control section and is made into a unit. Assume that the performance of the analysis section is that the number of simultaneous analysis items is 4 and the processing capacity is 300 samples per hour. When an apparatus is constructed from such units, it is possible to construct a model having the performance as shown in Table 1.

An object of the present invention is to provide an automatic chemical analyzer that can be developed into a series from small to large sizes by converting the functions of the device into units and by changing the configuration of these units. [Summary of the Invention] The present invention combines each function of the apparatus into a unit, arranges a plurality of analysis units between an operating unit and a sample rack receiving unit, and connects a plurality of analysis units between the sample supply section of the operating unit and the sample rack receiving unit. The sample racks are connected to each other by a sample rack transfer passage, and the sample racks are transferred so as to stop at positions corresponding to the sample receiving positions of the plurality of analysis units on the transfer passage. [Embodiment of the Invention] An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 4 show an example of the configuration of an automatic chemical analyzer based on the present invention. This example shows the case of a large machine in Table 2. The main body includes one operation unit 1, four reagent dispensing units 2 (two on the front, two on the rear), eight analysis units 3 (four on the front, four on the rear), and a sample. It consists of one receiving unit 4.
