1. An automatic analyzing device, comprising:
a rotating table including a plurality of placement parts on which a plurality of reaction cuvettes are placed, respectively,
a plurality of light receiving units provided in correspondence with the plurality of placement parts, respectively;
a light radiating unit configured to change from one of the reaction cuvettes to another on which light is radiated, the light radiating unit including
a rotating unit configured to rotate on a same axis as a rotation axis of the rotating table:
a light emitting unit configured to radiate light from a center of the rotating table, and
a mirror connected to the rotating unit and configured to change an emission direction of the light from the center of the rotating table by reflecting the light radiated from the light emitting unit, in conjunction with the rotation of the rotating unit;
a first light guiding duct located between the light emitting unit and the mirror, wherein the first light guiding duct is configured to conduct light radiated from the light emitting unit to the mirror; and
a plurality of second light guiding ducts (1) provided in correspondence with the plurality of placement parts, which are provided along a circumferential direction centered on the rotation axis of the rotating table, respectively, and (2) configured to guide the light received at the mirror from the light emitting unit via the first light guiding duct, to the plurality of light receiving units,
wherein the plurality of second light guiding ducts are located between the mirror and each of the plurality of light receiving units.
