PURPOSE:To provide a laser beam machine in which the constitution is compact and lightweight, and the dynamic characteristics are excellent. CONSTITUTION:A laser beam machine 6 consists of an optical system consisting of plane mirrors 21, 22 and a lens 29 to form the spot light S by focusing the laser beam L, a box 44 which supports the optical system and has the axix of rotation P which coincides with the optical axis 20 of the laser beam L, a first driving means consisting of a motor 45 to give the angular displacement to the box 44 about the axis of rotation P, a driving gear 46, an external gear 47 or the like, a second driving means 30 consisting of pulleys 31, 33 to give the angular displacement to the plane mirror 22 while the normal direction of the plane including the axis of rotation P being the axis of rotation Q, a belt 32, a motor 34 or the like. |
