PATTERN CONTROLLING DEVICE FOR LASER MARKER

摘要

Title of the Invention Pattern controlling device for laser marker A plurality of rotatable members are formed with patterns of given shapes which permit the passage of a laser beam, and which are arranged in concentric circles about the axis of rotation of the members. Part of each rotatable member is disposed in the path of the laser beam so that a combination of the individual patterns on the respective rotatable members define a pattern to be printed or marked. In this manner, a variety of printing or marking patterns can be easily obtained by merely controlling the angular position of the respective rotatable members.
