There is provided technology which is a component mounting machine which mounts electronic components onto a circuit substrate and is capable of displaying a movable region of an inner portion of the component mounting machine within a same image. The component mounting machine is provided with a fixed camera which monitors the inner portion of the component mounting machine and a display section which is capable of displaying a captured image of the fixed camera. The fixed camera is capable of imaging a range from a pickup position at which the suction nozzle picks up the electronic component which is supplied from the component feeder to a mounting position at which the electronic component is mounted onto the circuit substrate within the same image.
