  • the association information 9a shows an example of a table, but the present invention is not limited to this.
  • the association information may be information represented by a database such as a map other than the table.
  • the control unit 9 has a second identical component supply unit 20b and a third identical component supply unit 20c (a plurality of identical components) among a plurality of identical component supply units 20 stored in the storage unit.
  • An example is shown in which control is performed to select a second identical component supply unit 20b (another identical component supply unit) based on the remaining number of each component of the supply unit).
  • the control unit is based on the type of each head of a plurality of other identical component supply units stored in the storage unit of the substrate in order to suppress an increase in the mounting time of the component on the substrate. , It may be configured to control the selection of other same component supply units of the same head type. Further, the control unit controls to select another same component supply unit having a different nozzle type based on the nozzle type of each of the plurality of other identical component supply units stored in the storage unit of the substrate. It may be configured as follows.
  • the first identical component supply unit 20a is an example of the "one identical component supply unit" in the claims, but the present invention is not limited to this.
  • the second identical component supply unit or the third identical component supply unit may be the "one identical component supply unit" in the claims.
  • control processing of the control unit 9 may be performed by an event-driven type (event-driven type) process in which the process is executed in event units. In this case, it may be completely event-driven, or it may be a combination of event-driven and flow-driven.
  • event-driven type event-driven type
