Feeder state display system

A feeder state display system applied to a component mounting line including:

• multiple component mounters arranged along a conveyance path of a circuit board;
• a feeder storage that temporarily stores feeders to be replenished to the multiple component mounters and feeders removed from each component mounter, and an automatic exchanging device that moves over the feeder storage and the multiple component mounters to replenish a feeder taken out from the feeder storage to each component mounter and collect a feeder removed from each component mounter to the feeder storage, the feeder state display system comprising:
• a feeder management section configured to manage whether each feeder stored in the feeder storage is a feeder to be replenished to the component mounter or a feeder to be collected;
• and
• a state display section, being provided with each feeder on an end face part on a removal direction side or an upper end face part, which is configured to display a state of the feeder,
• wherein the feeder management section displays whether each feeder stored in the feeder storage is the “feeder to be replenished” or the “feeder to be collected”, on the state display section of each feeder.
