<p>PROBLEM TO BE SOLVED: To perform setup work easily, quickly and highly precisely by providing a control means for driving a driving means or a machining means when a light receiving means detects a light transmitted from a light emitting means through the through-hole of an instruction plate. SOLUTION: A card holder 4 and a card 5 are placed oppositely to each other at a fixed interval so as to be displaced in a relative manner and a sensor holder 6 for supporting a light emitting element for projecting a light toward the back surface of the card 5 and a light receiving element 8 for detecting a light transmitted through the through-hole 9 of the card 5 from the back surface to the surface side is provided. The light receiving element 8 sends out a current to a control part 23 according to a light transmitted through the through-hole 9 of the card 5. During a setup process, the setting of quenching position and condition are changed only by replacing the card 5 with another.</p> |
