ABSTRACT:
In a linear driving mechanism for electronic component mounting apparatus that performs mounting operation for mounting an electronic component on a substrate and linearly drives a transfer beam8in a Y direction using a linear motor, an object to be driven and the linear motor are disposed such that a position P of thrust generated by the linear motor for driving the transfer beam8in the Y direction approximately corresponds to a central position D1of inertial resistance of the object to be driven comprising movable portions such as transfer beam8, loading head9, and transfer plate12. Accordingly, twisting moment applied to the transfer beam8due to inertial force is eliminated in acceleration/deceleration, and loading position accuracy is ensured and a component life can be lengthened.
