An apparatus includes a system for guiding chemiluminescence and a system for preventing a variation in dark currents. The apparatus includes a first light shielding BOX having a sample container holder and a shutter unit therein, the shutter unit including a top plate which is partly formed by a movement of a plate member and a second light shielding BOX having a photodetector therein. While a measurement is not implemented, the shutter unit is closed to block entrance of stray light to the photodetector, and while a measurement is implemented, the plate member is moved to open the shutter unit, and the tip of the photodetector is inserted into a through hole formed in the top plate, so that the distance between the bottom of the sample container and a sensitive area of the photodetector is reduced to several millimeters or less.

What is claimed is: 1. An apparatus for chemiluminescent assay and detection, comprising:a container for storing a specimen;a holder for holding the container;a light-shielding housing having a top plate in which a through hole is formed so that the holder is placed over the through hole;a photodetector which is provided in the light-shielding housing opposite to the bottom of the container via the top plate of the light-shielding housing;a photodetector position control section for moving the photodetector relative to the container;at least one nozzle;at least one solution reservoir;at least one piping tube;at least one feed pump which is connected to the piping tube; anda nozzle position control section which causes a nozzle to move into the container,wherein the photodetector position control section controls the position of the photodetector so that an end surface of the photodetector is placed substantially at the same position as that of a surface of the top plate of the light-shielding housing or at a position closer to the container than top surface of the top plate, andthe nozzle position control section controls the nozzle so that the nozzle is inserted into the container.
