Claim:
1. An automatic analysis apparatus, comprising: a reaction disk holding a plurality of reaction containers, one or more of the reaction containers holding a sample to be analyzed; a reaction disk motor configured to drive the reaction disk; a display; an analyzer unit including a light source, an optical filter, a spectroscope, and a receptor element configured to measure light transmitted from the light source through a reaction container and a sample within the reaction container; and a control unit connected to the reaction disk motor, the analyzer unit, and the display, that includes a data storage unit, wherein the data storage unit stores: an initial transmitted light quantity distribution of each of the light source and the optical filter, a known transmitted light quantity distribution of each of the light source and the optical filter when the light source and the optical filter, respectively, have experimentally been determined to be deteriorated, and an initial transmitted light quantity distribution using light transmitted from the light source and passing through the optical filter, wherein the control unit is programmed to: cause the light source to emit light; obtain a measured transmitted light quantity distribution for a plurality of wavelengths detected by the receptor element when measuring the light emitted from the light source that is transmitted through the reaction container and through the sample to the receptor element via the spectroscope, store the measured transmitted light quantity distribution for the plurality of wavelengths, determine a first correlation between the initial transmitted light quantity distribution of the light source, the known transmitted light quantity distribution of the light source, and the initial transmitted light quantity distribution using light transmitted from the light source and passing through the optical filter, determine a second correlation between the initial transmitted light quantity distribution of the optical filter, the known transmitted light quantity distribution of the optical filter, and the initial transmitted light quantity distribution using light transmitted from the light source and passing through the optical filter, determine a degree of deterioration for the light source and the optical filter based on the first correlation and the measured transmitted light distribution for the plurality of wavelengths and the second correlation and the measured transmitted light distribution for the plurality of wavelengths, respectively, and cause the display to display an indication of the degree of deterioration for each of the light source and the optical filter.
