Component mounting machine and component mounting line

A component mounting machine comprising:

• a frame;
• a plurality of component supply devices which respectively include a plurality of component supply units each configured to supply components at component supply positions and the plurality of component supply devices are exchangeably equipped on the frame;
• a component transfer device which includes a mounting nozzle, the mounting nozzle configured to perform a lifting and lowering operation and pick up components from the component supply units of the component supply device which is equipped on the frame to mount the components on a board equipped on the frame, and a reference height as a reference of the lifting and lowering operation of the mounting nozzle is set;
• a height memory section which memorizes a height unique value that is unique for each of the component supply devices, the height unique value being and commonly set for each component supply unit of each of the component supply devices based on the plural unit heights of the component supply units of the component supply device, wherein the unit heights of the component supply units is represented as a relative unit height of the component supply position of each component supply unit when the component supply device is equipped on the frame with respect to the reference height;
• and
• a height correction control section which corrects a lowering operation stroke amount when the mounting nozzle picks up the components from the component supply units of the component supply device which is equipped on the frame based on the height unique value of the equipped component supply device memorized by the height memory section.
