Abstract: An automatic analysis apparatus comprises: a light source generating light having a center wavelength equal to or shorter than 340 nm; a fluorescent substance excited by the light source light, and generates light together with transmitted light from the light source, having a wavelength of 340 nm to 800 nm; a condenser lens; at least one slit; a reaction cell holding a reaction solution where a specimen and reagent are mixed, and that the light source light and the light from the fluorescent substance enter; and a detector that detects light transmitted through the reaction cell. The light source, fluorescent substance, condenser lens, and slit are provided along a straight light corresponding to the optical axis. The width of the slit's opening is equal to or narrower than the width of a ray forming an image of the light source at the position of the slit.

Abstract: An automatic analyzer is equipped with a sterilization mechanism removably attached to an opening of a container that holds a reagent and having an ultraviolet light generation section that radiates ultraviolet light; a suction nozzle removably attached, together with the sterilization mechanism, to the opening of the container; an analysis section adding the reagent drawn in by suction from the container via the suction nozzle to the reagent, and executing an analysis operation; and a control section exercising variable control over an irradiation light intensity of the ultraviolet light generated by the ultraviolet light generation section.

Abstract: An analyzer that has a simple configuration, that is inexpensive, that can improve safety, and that can inhibit proliferation of microorganisms using ultraviolet light is realized. A first electric power switch, a second electric power switch, and a third electric power switch are connected in series between an ultraviolet LED that irradiates an interior of a shared reagent storage container with ultraviolet light and a power supply that supplies electric power to the ultraviolet LED. The first electric power switch, the second electric power switch, and the third electric power switch are configured with two contact points and a connection section that connects and disconnects the two contact points. The first electric power switch is opened when a reagent storage door is opened, and the second electric power switch is opened in response to an action of extracting an ultraviolet irradiation section from a shared reagent storage container. The third electric power switch is opened when an amount of the reagent within the shared reagent storage container is equal to or smaller than a constant value. When one of the first electric power switch, the second electric power switch, and the third electric power switch is opened, supply of the electric power to the ultraviolet LED is intercepted.
