<p>PROBLEM TO BE SOLVED: To improve efficiency of a unit sequence or a specific unit sequence, in which it is difficult to image a component held by nozzles in nozzle arrays different from each other by one time movement operation (a scanning operation) of a head unit.SOLUTION: In the specific unit sequence, for a first component 3a supplied by a first component supply portion 4a, a first holding/imaging operation is performed that moves a head unit 5 from the first component supply portion 4a beyond a virtual boundary line VB so that the first component 3a goes through an upper position of an imaging portion 9, while holding the first component by nozzles 20 composing one nozzle array of a first nozzle array 21 and a second nozzle array 22. For a second component 3b supplied by a second component supply portion 4b, a second holding/imaging operation is performed that moves the head unit 5 from the second component supply portion 4b beyond the virtual boundary line VB so that the second component 3b goes through the upper position of the imaging portion 9, while holding the second component by nozzles 20 composing the other nozzle array.</p> |
