AUTOMATIC ANALYSIS DEVICE

摘要

The present invention reduces the amount of time related to adjusting the position of light-receiving elements. A light source generates light. A spectrometer separates, by wavelength, the light that has been generated from the light source and has passed through a liquid mixture of a sample and a reagent. A light-receiving unit (8) has a plurality of light-receiving elements (81) for receiving light from the spectrometer. Each of the plurality of light-receiving elements (81) receives light related to a wavelength band corresponding to the layout position, and generates a signal that corresponds to the received light. A storage unit (11) associates and stores a plurality of light-receiving element identifiers and a plurality of wavelength band identifiers. A selection unit (13) selects, from among the plurality of light-receiving elements, a specific light-receiving element corresponding to the specific light-receiving identifier associated with the wavelength band identifier for a wavelength band that corresponds to a measurement item of the sample. A calculation unit (15) calculates the optical absorbance related to the measurement item on the basis of the signal from the specific light-receiving element that has been selected.
