Component mounting machine

A component mounting machine that picks up a component supplied from a component supply device and mounts the component on a circuit board, the component mounting machine comprising:

• multiple devices that execute a component pickup and mounting operation of the component mounting machine to pick up and mount the component, the multiple devices including:
• the component supply device,
• an attachable and detachable device that is attachably and detachably attached to the component mounting machine and that picks up the component supplied from the component supply device,
• a moving device that moves the attachable and detachable device, and
• a conveyor that carries the circuit board;
• a control device operably connected to the multiple devices and programmed to control the multiple devices to execute the component pickup and mounting operation of the component mounting machine;
• and, wherein
• the attachable and detachable device is provided with a field programmable gate array (FPGA) that is programmed to operate each of a plurality of functions of the attachable and detachable device by communicating with the control device, and
• the FPGA is programmed to have a clock gating function of reducing an electric current flowing into the attachable and detachable device by stopping processing on a function that is not used, out of the functions of the attachable and detachable device, when the attachable and detachable device is in a state capable of being removed by an operator.
