ABSTRACT:
A photometric apparatus for an automatic chemical analyzer is disclosed, which comprises a cell assembly, a photometric section, a drive unit, an edge detecting circuit, a signal generator and a control circuit. The cell assembly has cells for accommodating samples and arranged in a predetermined manner. The photometric section forms a light path for measurement and provides a detection signal obtained from the light path. The cell assembly and light path are moved relatively at a predetermined speed by the drive unit. With this movement, the cells are successively brought to a position on the light path. The edge detecting circuit detects an optical edge of the cell assembly from the detection signal of the photometric section. The signal generator is sensitive to the edge detection by the edge detecting circuit and generates an enable signal when a predetermined portion of each cell is brought to the position on the light path. The control circuit provides the photometric signal from the photometric section for analysis in response to the enable signal.
