Abstract
An engraving head that includes a movement mechanism for moving an engraving stylus within the body housing of the engraving apparatus is provided. The movement of the engraving stylus causes the tip of the engraving stylus to approach and recede from an engraving surface. The movement mechanism contains a movable body and a first energizing means. The movable body moves in association with a movement space member's inner circumference. The movement space member is positioned inside the body housing. The first energizing means is employed to energize the movable body in a direction away from the engraving surface. Additionally, a second energizing means serves to energize the movable body in a direction towards the engraving surface against the opposing energizing force of the first energizing means. The second energizing means may be, for example, compressed gas. As the movable body travels downward towards the engraving surface, the tip portion of the engraving stylus also approaches the engraving surface. When the energizing force of the second energizing means is released or is less than a predetermined value, the movable body and the tip portion of the engraving stylus recede …
