ABSTRACT:
A parts mounting apparatus includes a structure (34) on which a spindle (31) is supported to be movable up and down, and the spindle has a vacuum suction path (36). Either a normal nozzle (50) or a nozzle for image recognition (141) can be attached to a lower end of the spindle. When the normal nozzle is attached to the spindle, parts positioning jaws (61a-62b) supported on the structure performs a centering operation of the parts sucked to the normal nozzle in accordance with vertical movement of the spindle by a cam device (90) and a motor (93). When the nozzle for image recognition is attached to the spindle, a CPU (201) controls the motor so that rise of the spindle can be stopped before the nozzle for image recognition enters an operating region of the jaws.
