<p><P>PROBLEM TO BE SOLVED: To provide a laser marking device for effectively protecting a laser light source unit or the like, mounted on an freely oscillating disposed pendulum member, from various vibrations or impacts. <P>SOLUTION: The laser marking device comprises a body housing having an opening window section for irradiating laser beams irradiated in the vertical and horizontal directions, a pendulum member oscillatably mounted in a suspended state in the body housing via a gimbal mechanism, and the laser light source unit that is mounted at a predetermined position of the pendulum member and has a laser beam generating means and an optical means for irradiating the laser beam from the laser beam generating means in the predetermined direction. A regulation member that faces the lower free-end side of the pendulum member and is made of an impact-cushioning material is mounted inside the body housing. The regulation member is provided with a regulating hole which the lower-free end of the pendulum member is inserted into with a predetermined space and the lower free end side abuts against during oscillations that are larger than required of the pendulum member; and the abutting surface of the regulating hole is provided with many cut grooves axially at predetermined intervals. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
