Abstract: A mounting head is formed of a main body section and a plurality of nozzle holding units, and each of the plurality of nozzle holding units is mounted to the main body section in an exchangeable manner. The height of a suction nozzle when the mounting head is moving over a circuit board is different for each of the plurality of nozzle holding units. In a mounting machine using such a mounting head, due to an installation position optimization program being executed, an installation position of a tape feeder in which electronic components which are scheduled to be mounted to the circuit board which is conveyed by one of a pair of conveyance devices are stored is set to a tape feeder installation table of a supply device of a side close to the one conveyance device of the pair of supply devices.
