摘要：
In a tool length measuring method measuring a length of a tool based on a movement amount of the tool from a predetermined position when the tool is moved from the predetermined position in a predetermined direction and interrupts a laser beam, the movement of the tool in a direction in which the tool approaches a main body of a laser device is stopped when a static signal indicating that the tool is interrupting the laser beam is detected.
