The respective mechanisms constituting the component mounting unit 6 and the component supplying unit 7 are controlled by a control unit 17 provided in each of the mounting machines M1 to M3. The control unit 17 has a storage region, and production data 18 shown in FIG. 3 is stored in the storage region. The production data 18 includes various data used for producing the substrate 12 on which the component has been mounted, and includes mount data 19, component data 20, component group data 21, and setting data 22.

The mount data 19 is data used for mounting the component on the substrate 12, and includes a “mount coordinate” 19a, a “mount angle” 19b, an “suction position” 19c, and a “component ID” 19d which are associated with each component. The “mount coordinate” 19a indicates an XY coordinate of the mounting position set to the substrate 12. The “mount angle” 19b indicates a mount angle of the component on the horizontal plane. The “suction position” 19c indicates a slot No. of the tape feeder 13 to which the component is supplied. The “component ID” 19d indicates information (identification information) for identifying each component.
