#An embodiment of an electronic component mounting apparatus of the invention will be described with reference to the drawings. FIG. 1 is a plan view of an electronic component mounting apparatus 1, FIG. 2 is a front view of the electronic component mounting apparatus 1, and FIG. 3 is a right side view of the electronic component mounting apparatus 1. A plurality of component feeding units 3 for feeding a variety of electronic components one by one to each of component feeding positions (component pickup positions) is attachably and detachably aligned and fixed on feeder bases 3A, 3B, 3C, and 3D on a base 2 in the apparatus 1. A feed conveyer 4, a positioning portion 5, and a discharge conveyer 6 are provided between groups of the units 3 facing to each other. The feed conveyer 4 conveys a printed board P received from an upstream to the positioning portion 5, an electronic component is mounted on the printed board P positioned by a positioning device (not shown) in the positioning portion 5, and the printed board P is conveyed to the discharge conveyer 6.

#A numeral 8 designates a pair of beams extending in an X direction. Each of the beams 8 respectively moves in a Y direction above the printed board P on the positioning portion 5 or the component feeding positions (component pickup positions) of the component feeding units 3 as sliders 11 fixed to each of the beams 8 slide along a pair of left and right guides 10, driven by each of linear motors 9. Each of the linear motors 9 has a pair of upper and lower stationary members 9A fixed on the base 2 and a moving member 9B fixed to a lower part of an attachment board 8A provided on each end of the beam 8.

#Each of the beams 8 is provided with a mounting head body 7 which moves in a longitudinal direction, i.e., in the X direction along a guide 13 driven by the linear motor 14. The linear motor 14 has a pair of front and back stationary members 14A fixed to the beam 8 and a moving member 14B provided on the mounting head body 7 and between the stationary members 14A.
