| 1. A linear driving mechanism for an electronic component mounting apparatus that performs mounting operation for mounting
an electronic component on a substrate and linearly drives an object to be driven in a first direction, the linear driving
mechanism comprising:
a guide section for guiding the object to be driven in the first direction;
a linear motor for driving the object to be driven in the first direction; and
a base frame connectively attached to the linear motor and extending along the guide section in the first direction,
wherein the object to be driven and the linear motor are disposed on the guide section such that a thrust-generating point
of the linear motor is approximately located at an inertial resistance center position of the object to be driven,
wherein the linear driving mechanism further comprises a linear scale and a linear head, the linear scale is fixedly arranged
on an inner side of the base frame in the first direction, and the linear head outputs a position signal in the first direction
and is arranged on the object to be driven,
wherein the linear scale and the linear head are opposed to each other, and the linear head is moved with respect to the linear
scale which is fixedly arranged.
