PURPOSE:To provide the laser beam machine which is constituted to easily recognize the processing section of a work and to surely process the work. CONSTITUTION:This laser beam machine has a laser generator 1, an optical fiber 3 on which the laser beam outputted from this laser generator 1 is made incident from one end face, a body 4 which is to be driven and holds the other end of the optical fiber 3, a driving mechanism 5 for driving the body 4 to be driven, a condenser lens 8 which focuses the laser beam emitted from the other end face of the optical fiber 3 and irradiates the surface of a coating film 9a with the laser beam and an annular mask 14 which is freely attachably and detachably mounted on the surface of this coating film 9a and regulates the irradiation range of the surface of the coating film 9a by the laser beam emitted from the optical fiber 3 when the other end of the optical fiber 3 is driven together with the body 4 to be driven. |
