ABSTRACT:
A component mounting device adapted to mount components such IC or the like on a printed circuit board that includes replaceable pick up nozzles to accommodate different types of components to be picked up. A sensing station is provided that permits the pick up nozzle to be verified as the correct one. The same sensing station is employed to sense both the orientation of a component that is picked up and also whether the component is correctly oriented for deposit. This is done by measuring projected lengths in a plane with a photo sensitive device and by making calculations in accordance with trigonometric relationships.
