Abstract: A work system includes a mounting system which mounts a component on a board and an unmanned conveyance system having an unmanned conveyance vehicle. The unmanned conveyance system includes a first notifier which notifies the mounting system of an arrival notification indicating that the unmanned conveyance vehicle arrives at a position where separating the feeder carriage from the base starts, and a first processor which causes the unmanned conveyance vehicle to travel in a direction away from the base upon receiving, from the mounting system, a release notification indicating that a connection of the feeder carriage is released. The mounting system includes a second processor which causes the connection mechanism to release the connection of the feeder carriage upon receiving the arrival notification, and a second notifier which notifies the unmanned conveyance system of the release notification upon being informed of completion of the release operation.
