PROBLEM TO BE SOLVED: To positively recognize the position of parts being retained by a retainer, without stopping the retainer. SOLUTION: When a placement head 5 reaches a specified position on a part image-pickup camera 14, a CPU 25 issues a reading command, and an image output signal picked up by opening the shutter of a next vertical synchronous signal is taken into a frame memory 29. The reading end time is read by the CPU 25. The time, which is the difference to the time when the reading command is issued, is calculated, and the misalignment of an electronic component 7 is recognized based on the position of a suction nozzle 6 on the image- pickup being calculated according to the difference. |
