1. A component mounting machine comprising:
an illumination light source configured to illuminate an identification target which is attached to an upper surface of a component supplied by a component supply device, from obliquely above;
a mounting head configured to pick up the component to mount the component on a circuit board;
a camera configured to move integrally with the mounting head, to image the identification target on the upper surface of the component, and to image a board mark of the circuit board, which is illuminated by the illumination light source from obliquely above;
an image processing device configured to process an image captured by the camera to identify the identification target;
a head moving device configured to move the mounting head in each of an X direction, a Y direction, and a Z direction;
a control device configured to control the head moving device to moves the mounting head in the Z direction such that a height of the illumination light source from the upper surface of the component becomes a predetermined height; and
an electric component holding frame protruding from a side of the mounting head and provided to move integrally with the mounting head, which is configured to hold a control board or cables of the mounting head,
wherein the illumination light source is attached to a lower portion of the electric component holding frame.
