A laser is mounted at a transverse edge of the L-shaped water supply block, and the hollow metal structural member is mounted at a vertical edge of the L-shaped water supply block, so that diffuse reflection light formed after a laser irradiates the skin enters a cavity of the hollow metal structural member.
