<P>PROBLEM TO BE SOLVED: To improve usability of a nozzle stocker fitted on an electronic circuit component mounting machine by housing a suction head. <P>SOLUTION: A plurality of nozzle housing holes 624 are formed in a nozzle housing base 620 of a nozzle stocker 600, to house suction nozzles. Further, a two-dimensional code 696 and a reference mark 698 are set on the nozzle stocker 600, and stocker information is recorded on the two-dimensional code 696. A fluorescent layer 634 is formed on the bottom of a lane hole 628 of the nozzle housing hole 624, and an illuminator of a mark imaging device for imaging the reference mark 698 and the two-dimensional code 696 irradiates the fluorescent layer 634 with a blue ray containing much ultraviolet ray. The fluorescent layer 634 absorbs the ultraviolet ray, to emit visible light. If a suction nozzle is housed in a nozzle housing hole 624, the visible light is not emitted. Accordingly, the presence of the suction nozzle can be detected by the mark imaging device for imaging the nozzle housing hole 624. <P>COPYRIGHT: (C)2010,JPO&INPIT |
