COMPONENT MOUNTING DEVICE

PROBLEM TO BE SOLVED: To provide a component mounting device capable of suppressing a large sized (heavy) head unit in the case of recognizing a component and a substrate with the provision of an imaging unit on the head unit.SOLUTION: A component mounting device 100 includes: a head unit 50 capable of mounting a component 2 adsorbed by a nozzle 5 on a substrate 1; and an imaging unit 60 disposed on the head unit 50 relatively movably to the head unit 50. An optical path L1 for imaging the component 2 adsorbed by the nozzle 5 and an optical path L2 for imaging the substrate 1 are switched over, so that the imaging unit 60 relatively movable to the head unit 50 selectively images the component 2 or the substrate 1.
