<P>PROBLEM TO BE SOLVED: To provide an electronic component mounting device capable of keeping position accuracy at the tip of a nozzle even in a structure including a plurality of nozzle units arranged in the same nozzle row and having a plurality of nozzle shafts driven to rotate by the same motor, and to provide a mounting head. <P>SOLUTION: Driving pulleys 23A and 23B of a first motor and a second motor are provided on a plurality of nozzle units so that a working direction of first external force applied by tension of a first driving belt 19A and a working direction of second external force applied by tension of a second driving belt 19B are reverse to each other on respective shaft members 13A and 13B of the plurality of linearly arranged nozzle units. Thus, lateral external force applied to the respective shaft members can be minimized, and inclination due to the external force of the shaft member can be suppressed as much as possible to secure the position accuracy at the tip of the nozzle. <P>COPYRIGHT: (C)2009,JPO&INPIT |
