PURPOSE: To omit a wasteful operation and to improve an electronic component mounting efficiency by recognizing the shape of the component before the component is sucked by a suction nozzle, abandoning the component as it is when mounting is improper, and immediately disposing oppositely a next electronic component.
CONSTITUTION: A mounting head 21 is disposed above the sucking position of a component supply unit 23, and the shape of an electronic component P of its sucked position is recognized by a recognition camera 18 through a suction nozzle 1 and a light transmission plate 5. If a defect 27 is provided on the component P or the lead of a component with leads is lacked or bent in an inadequate shape, its sucking operation is not started, but a part cassette 26 is operated as it is, a next electronic component P is fed to a sucking position, and its shape is again recognized by the camera 18. If the shape of the component P is proper, the component P is sucked by the nozzle 1, the sucked component P is disposed above a predetermined mounting position of a circuit board 24, and accurately mounted at a predetermined position on the board 24.
