The unmanned conveyance system includes a first notifier which notifies the mounting system of an arrival notification indicating that the unmanned conveyance vehicle transfers the feeder carriage to a position where an operation of connecting the feeder carriage to 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 connection completion indicating that a connection of the feeder carriage is completed. The mounting system includes a second processor which causes the connection mechanism to connect the feeder carriage upon receiving the arrival notification, and a second notifier which notifies the unmanned conveyance system of the connection completion upon being informed of completion of the connection.
