<p>Electronic component mounting apparatus directed to quick adjustment of a positional relationship between two axes when an error occurs in the positional relationship between the axes when a beam (8) is moved by two drive sources. According to movement of the beam (8) for component picking and mounting operations, linear scale signals (outputs relating to positions of one drive axis and another drive axes) from linear scale reading heads (100,101) are inputted to a Y2 driver (96) and a Y1 driver (97) respectively. Since each of the Y2 driver (96) and the Y1 driver (97) has a calculation means and a control means, when inputted with both the linear scale signals, each of the Y2 driver (96) and the Y1 driver (97) calculates a difference between positions of the drive axes (Y1,Y2) of the beam (8) by the calculation means, and controls a moving member (9B) of a linear motor by the control means based on the difference so as to increase thrust of one drive axis in a case where the one drive axis is in a more backward position than another drive axis and reduces the thrust of one drive axis in a case where the one drive axis in a more forward position than another drive axis. <IMAGE></p> |
