<P>PROBLEM TO BE SOLVED: To provide an electronic component mounting apparatus which can control the rotation position of the θ axis with high accuracy without providing an encoder for full-closed loop control on the nozzle side. <P>SOLUTION: The electronic component mounting apparatus for mounting an electronic component held by a nozzle at an electronic component supply section onto a substrate includes a nozzle 17a which is free to pivot about the axis, a θ-axis motor 19a for pivoting the nozzle, and a belt 19e for transmitting the driving force of the θ-axis motor to the nozzle. The electronic component mounting apparatus is equipped with a belt mark 19f attached to the belt, a belt mark detection sensor 19g for detecting the belt mark, and a means for correcting the deviation in rotation position of the nozzle and the θ-axis motor with the output of the belt mark detection sensor as a reference. <P>COPYRIGHT: (C)2009,JPO&INPIT |
