PURPOSE:To take up electronic parts surely by detecting the take-up heights of the electronic parts with a height detecting means beforehand, and by adjusting the ascending or descending stroke of a nozzle on the basis of the detected data. CONSTITUTION:A laser device 22 is positioned above a take-up position (A) by protruding the rod of a cylinder 23. Then, pitch-moving a table 11 in the transverse direction along a feed screw 8, the height of the upper surface of an electronic part P in each parts feeder 7 on the table 11 is detected. And a blanket 21 or the laser device 22 are moved back by drawing the rod in, the electronic part (P) in each parts feeder 7 is taken up by a nozzle 3 by air-suction index-rotating a rotary head 1, and is conveyed and mounted on to a board 10. On the basis of detected data obtained at this time, the ascending or descending stroke of the nozzle 3 is adjusted. This makes it possible to take up the electronic parts P surely. |
