To facilitate the alignment control between control parts in a case and the case.

When a keyboard 13 is manually operated to enter an identification information (ID code) read instruction to an excited computer 12, the computer 12 reads the ID code 5 from a security chip 4, converts the read-out ID code 5 into bar code information, and outputs it to an ID code reader 9. The ID code reader 9 outputs the bar code information to an ID number process section 15. The ID number process section 15 outputs and radiates a laser beam 17 with the energy corresponding to the bar code information to the outside face of the case 2, thereby the bar code information 18 corresponding to the ID code 5 is automatically printed with the outside face of the case 2 dissolved.
