An apparatus for measuring deviations of positions of leads of an electrical component comprises a light emitting unit for radiating a laser light from below toward the leads projecting from a molding of the electrical component sucked to a nozzle of a pick and place head. First and second photodetectors are disposed at both sides of the light emitting unit for detecting laser lights reflected at the leads, so as to enable to effect the measurement rapidly and accurately. |
