Electronic-component mounting apparatus

An electronic-component mounting apparatus, including

• a frame member,
• a movable member supported by said frame member such that said movable member is movable relative to the frame member,
• a moving device which moves said movable member relative to said frame member,
• a mounting head which is provided on said movable member and mounts an electronic component on an object such as a printed circuit board, and
• at least two devices selected from (a) at least one rotating device including a first actuator which rotates said mounting head about an axis line thereof, (b) at least one advancing and retracting device including a second actuator which advances and retracts said mounting head in opposite directions parallel to an axis line thereof, respectively, (c) at least one vacuum-supply control device including a third actuator which controls vacuum supply to a suction nozzle of said mounting head, and (d) at least one suction-nozzle selecting device including a fourth actuator which selects one of a plurality of suction nozzles of said mounting head,
• said at least two devices including at least two actuators selected from at least one said first actuator, at least one said second actuator, at least one said third actuator, and at least one said fourth actuator,
• wherein the improvement comprises:
• said at least two actuators including at least two electric actuators which are provided on said movable member and are operable on electric energy;
• a power source which is provided on said frame member and provides said electric energy;
• a main control device which is provided on said frame member;
• an actuator control device which is provided on said movable member and controls said electric actuators;
• an electricity supplying device which includes a first supplying section provided on said frame member and a second supplying section provided on said movable member and which supplies said electric energy from said power source to said actuator control device, without having any wire connection between said first and second supplying sections;
• and
• an information transmitting device which includes a first transmitting section provided on said frame member and a second transmitting section provided on said movable member and which transmits, between said main control device and said actuator control device, information needed to control said electric actuators, without having any wire connection between said first and second transmitting sections.
