Claim of US Patent No. 10,117,369

1. A component transfer device of a component mounter comprising:a single nozzle head that has one suction nozzle which picks up a component from a supply position by making an internal pressure of the suction nozzle negative and mounts the component on a board held at a fixed position by raising the internal pressure of the suction nozzle;
a multiple nozzle head that has multiple suction nozzles;
a head holding section that exchangeably holds the single nozzle head and the multiple nozzle head, the head holding section including a supply passage that is connected to the suction nozzle of the single nozzle head and supplies a negative pressure or a positive pressure to the suction nozzle of the single nozzle head, a negative pressure supply passage being connected to the supply passage, and a positive pressure supply passage being connected to the supply passage;
a pickup/mounting driving section provided on the head holding section that connects with the suction nozzle of the held single nozzle head and a selected suction nozzle of the held multiple nozzle head, and raises/lowers the internal pressure of the suction nozzle; and
a head driving section that drives the head holding section and the held single nozzle head or the held multiple nozzle head between the supply position and the board held at a fixed position;
wherein the pickup/mounting driving device, when making the suction nozzle of the held single nozzle head perform mounting of the component, connects the positive pressure supply passage to a positive pressure source, cuts off the negative pressure supply passage from a negative pressure source, and connects the negative pressure supply passage to the atmosphere.
