Abstract

PROBLEM TO BE SOLVED: To provide a terminal equipment that is constructed so as to prevent unqualified use of the equipment by impeding the start up of the equipment when a break of the seal of the main cabinet was detected. SOLUTION: When the seal of the main cabinet was broken for an unqualified use, the memory device 32 rewrites or erases the data in it upon receiving a detection signal from the seal break detecting device 33. When the CPU 31 starts up the terminal equipment, the software of the terminal equipment instructs the CPU 31 to examine a specific data or the whole data in the memory device 32. When the data in the memory device 32 have been rewritten or erased, the terminal equipment is unable to start and stops the whole operation. This prevents the terminal equipment from an improper use as it rejects unqualified break of the seal and alteration of data besides.
