Semiconductor device for controlling game machine, and inspection apparatus and inspection method therefor

摘要: PROBLEM TO BE SOLVED: To provide a game machine control chip which is comparatively easily discriminated from the imitation or unauthorizedly remodelled article of chip, and to an inspection method apparatus therefor. SOLUTION: A lot number (L) being first kind identification information, etc., printed in printing area 10 package, value hash function obtained by performing calculation with information as variable number, check code 12 machine-readable (e.g., two-dimensional code) encoding characters numerals codes, 14 package. The can be using general technique, it difficult for person recognize what content included at glance but optical reader correctly performs reading high speed. COPYRIGHT: (C)2006,JPO&NCIPI
