LINEAR MOTOR UNIT AND ELECTRONIC COMPONENT PLACING APPARATUS PROVIDED WITH THE LINEAR MOTOR UNIT

摘要

A linear motor unit is provided with a plurality of linear motors each of which has a stator, a movable element which linearly reciprocates along the stator, and a magnetic sensor which can detect the position of the movable element. The magnetic sensors of the adjacent linear motors are arranged at different positions in the moving direction of the movable element.
