Claims

[Claims for Utility Model Registration] 1. In a laser processing machine in which a rotating cylinder is supported in a housing so as to be relatively rotatable, and a laser beam is passed through the rotating cylinder, a floating ring is attached to each of the rotating cylinder and the housing. one of the rotary cylinder and the floating ring is provided with an engaging member, and the other is provided with a first engaging part and a second engaging part that can be engaged with the engaging member. The floating ring is provided at predetermined angular intervals in the rotational direction, and the floating ring is provided with a dog for detecting the position of both ends of rotation, and the housing is provided with a dog that is engaged with the position detecting dog for both ends of rotation when the ring is at both ends of rotation. 1. A rotation range regulating device for a laser processing machine, comprising rotation stoppers arranged at respective positions. 2. Practical use characterized in that the engaging member is an engaging pin integrally attached to the rotating cylinder, and the first and second engaging parts are wall surfaces at both ends in the rotating direction of a fan-shaped convex part formed on the floating ring. A rotation range regulating device for a laser processing machine according to claim 1 of the patent registration claim.
