<P>PROBLEM TO BE SOLVED: To suppress the generation of vibration or noise in respective parts of a device such as a main body frame or the like or to improve component supplying accuracy or component mounting accuracy, in an electronic circuit component mounting system. <P>SOLUTION: Two sets of component supplying tables 30, 32 and component mounting heads 200, 202 are retained by the main body frame 10 so as to be turnable about vertical axial lines, then, a feeder 42 is positioned by turning at a component supplying position, and a component mounting unit 212 is stopped at a component receiving position or the like. A wiring board retaining device 16 is equipped with two sets of XY tables 350, 352 whereby two sheets of wiring boards 18 can move simultaneously. Components can be mounted in parallel to the same kinds of wiring boards 18, for example. In this case, the tables 30, 32 and the component mounting heads 200, 202 are turned into reverse directions at the same time with the same acceleration or deceleration. By this constitution, forces in the reverse directions are exerted simultaneously on the main body frame 10 upon rotation whereby vibrations are canceled to each other and suppressed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
