Automatic analyzer and assembly support system thereof

An assembly support system, comprising:

• automatic analyzer, comprising:
• a light source and a spectroscopic detector;
• a plurality of dispensing units;
• and
• a plurality of pump units connected to the respective dispensing units, wherein each of the plurality of pump units includes:
• a syringe tube that has a liquid port at one end and an opening at another end;
• a syringe base that is attached to the opening at the other end of the syringe tube;
• a plunger that penetrates the syringe base and whose tip end is inserted inside the syringe tube;
• a seal piece that is configured to seal a gap between the plunger and the syringe base;
• an actuator that individually drives the respective pump unit;
• and
• a power transmission mechanism that connects the actuator and the plunger,
• each plunger of the plurality of pump units has an individually set diameter and a different thickness, and
• at least one of the syringe base and the syringe tube is color coded for a molding color according to the a diameter of the corresponding plunger, plunger to represent and represents the diameter of the corresponding plunger,
• a monitor;
• a camera;
• a memory configured to store registration data indicating assembly positions and the colors of the syringe tube and the syringe base of each of the plurality of pump units;
• and
• at least one processor that is configured to:
• collate a captured image of the plurality of pump units with the registration data,
• determine whether assembly positions of the syringe tube and the syringe base are correct, and display and output a determination result on the monitor, and
• upon determining the assembly positions of the syringe tube and the syringe base are incorrect, output an interlock signal for prohibiting a dispensing operation to the automatic analyzer.
