  • Patent number: 7618589
    Abstract: An automatic dispenser includes a dispensing head, a transporter, a controller, sensors, and an adjustor. The dispensing head accommodates a plurality of dispensing tips and draws liquid into and ejects liquid from the dispensing tips. The transporter moves the dispensing head within an XYZ space. The controller controls drawing and ejecting of liquid by the dispensing head and movement of the dispensing head by the transporter. The sensors detect whether dispensing tips are mounted in the dispensing head. The adjustor aligns the reference positions of the dispensing head and the sensors in the XY plane.
