Analyzing apparatus

An automatic analyzing apparatus comprising:

• a pipette chip rack having at least one plane and capable of holding one or a plurality of pipette chips, each of the pipette chips including a measurement cell part through which light can be transmitted;
• a pipette on which the pipette chip is mounted, the pipette sucking and discharging a specimen, wherein the pipette is surrounded by a first light shield comprising a light absorbing surface;
• a conveyance unit for conveying the pipette on which the pipette chip has been mounted;
• a measurement unit including an opening that receives the pipette chip therein and measuring light emitted from the specimen inside the pipette chip;
• and
• a detection unit comprising a second light shield shielding an opening of the detection unit, wherein the second light shield has an opening for receiving a tip of the pipette, wherein the first light shield and the second light shield having a nested structure when the pipette is received at the detection unit,
• wherein:
• the pipette chip rack includes a guide that orients one plane of the pipette chip to a specific direction on a horizontal surface,
• the conveyance unit conveys, after the pipette chip arranged in the pipette chip rack is mounted on the pipette, the pipette chip into the measurement unit and arranges the pipette chip so that the plane of the pipette chip becomes orthogonal to an optical axis of the measurement unit, and
• the measurement unit measures light emitted from the specimen in the pipette chip or light that has transmitted the specimen.
