AUTOMATIC ANALYSIS SYSTEM

According to the present invention, a chemical dispensing mechanism 115 is provided with a liquid surface sensor for detecting the liquid surface of a chemical. A chemical container 122 is mounted on a chemical disk 116. A computer 132 has a calculation control unit comprising a control unit 140 and a calculation unit 141 and generating a control signal for controlling the operation of the chemical dispensing mechanism 115. The calculation control unit performs a first raising operation, in which a chemical stored in the chemical container 122 is suctioned by the chemical dispensing mechanism 115 and the chemical dispensing mechanism is then raised up to a first bubble detection position, determines whether a liquid surface is present by acquiring the detection result of the liquid surface sensor, and outputs an alert indicating the presence of a bubble on the liquid surface when the liquid surface has been determined to be absent. The first bubble detection position is the position at which the tip section of a dispensing nozzle of the chemical dispensing mechanism 115 remains inside the liquid when there are no bubbles present on the liquid surface, and is exposed from the inside of the liquid when there are bubbles present on the liquid surface.
