摘要:
An automatic laser beam machining apparatus with a sensor that detects whether a user slots a fare (e.g. coins) for starting laser beam machining of an article. The apparatus includes a video camera that can take an image (such as the face of a user) and reproduce it by laser machining upon an article. The article is removed from a stack of the articles and automatically properly positioned for laser machining with safety and ease. A mark is provided on the article for detecting the machining condition (e.g. the material or a shape of the article) by using a sensor.
