In a mounting apparatus for electronic components, a command from a host computer is transmitted to a linear motor M via a motion controller and a servo amplifier to thereby drive a mounting head H1 or a mounting head H2. To prevent collision between the two mounting heads H1, H2, position information from a linear encoder E is fed back to not only the servo amplifier, but also the motion controller. Once determining that the two mounting heads H1, H2 collide, the motion controller applies brake to the mounting heads H1, H2 to avoid collision therebetween, regardless of the command from the host computer.
