PURPOSE:To prevent the mistake of cutting at the time of the cutting of a disused pin, and to check the pin after cutting easily by forming a mark displaying an unwanted pin near the disused pin and easily discriminating the position of cutting of the disused pin by visual sense. CONSTITUTION:A mark 8 displaying the position of the so-called disused pin 7 not connected to an external circuit is shaped near the disused pin 7. Consequently, not only erroneous cutting at a time when the disused pin 7 is cut is prevented but also verification after cutting is facilitated. Since the mark 8 can also be employed as a recognition mark for an automatic machine, the presence of the mark 8 is recognized, and the disused pin 7 can also be cut automatically. |
