Abstract
A marking device is disclosed which efficiently reduces damage affecting the gimbal mechanism even when such is used under sever conditions and is dropped from a high position. A marking device has a support mounted inside a housing, a light source unit holder swingably suspended by the support through a gimbal mechanism, and a light source unit mounted on the light source unit holder so as to diffuse a light flux only in a single direction to radiate a line of light. The support is coupled with said housing 1 through dampers with upper portion and lower portion formed of an impact absorber, and when outside impact is applied, the damper absorbs impact energy to prevent the impact force from being transmitting to the support.
