In a linear driving mechanism which is arranged in electronic component mounting apparatus that performs mounting operation for mounting an electronic component on a substrate and linearly drives a transfer beam 8 in 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 beam 8 in the Y direction approximately corresponds to a central position D1 of inertial resistance of the object to be driven comprising movable portions such as transfer beam 8, loading head 9, and transfer plate 12. Accordingly, twisting moment applied to the transfer beam 8 due to inertial force is eliminated in acceleration/deceleration, and loading position accuracy is ensured and a component life can be lengthened. ® KIPO & WIPO 2007 |
