DETERMINATION DEVICE AND COMPONENT MOUNTING APPARATUS HAVING SAME

The present invention provides technology that makes it possible to efficiently mount components in a state where a plurality of component feeders are previously attached. This determination device determines a component feeder to be used from among a plurality of component feeders attached to a feeder holding unit. The determination device acquires attachment positions at which the component feeders are attached and the types of components housed in the component feeders, and if a plurality of first same type component feeders are attached to the feeder holding unit when a first specific component feeder runs out of components in a case where a first specific type of component supplied from the first specific component feeder and a second specific type of component supplied from a secondspecific component feeder are simultaneously picked up by a mounting head, determines, as a component feeder for supplying the first specific type of component, one of the first same type component feeders which is attached a
