An electronic component mounting apparatus is configured to adjust a positional relationship between two axes when an error occurs in the positional relationship between the axes when a beam is moved by two drive sources. According to movement of the beam for component picking and mounting operations, linear scale signals from linear scale reading heads are inputted to a Ydriver and a Ydriver, respectively. Each of the Ydriver and the Ydriver calculates a difference between positions of the drive axes of the beam and controls a moving member of a linear motor based on the difference so as to increase thrust of one drive axis when the one drive axis is in a more backward position than another drive axis and to reduce the thrust of one drive axis when the one drive axis in a more forward position than another drive axis.
