Scribe device, scribe method, and tip holder

摘要

A tip 14 is rotatably attached to a tip holder 10. The tip holder 10 is made into a cylindrical shape and its end has an installation part 16. An opening is arranged at a holder joint. The tip holder 10 is attracted by a magnet for attachment so that detaching and attaching can be performed easily. Tip offset data is recorded as a 2-dimensional code 17 on the surface of the tip holder 10. When replacing the tip holder, the offset data is read out and inputted to a scribe device, thereby canceling the offset. This eliminates the operation required for correction when attaching/detaching the tip holder and enables easy tip replacement during a short time of device stop.
