摘要： PROBLEM TO BE SOLVED: To realize to surely hold history information of shutting-off and warning reason occurrence, without having the information deleted, even when a power source voltage drops or hardware are reset due to failures of a microcomputer in a gas meter. SOLUTION: A history information memory 64 stores and holds history information without the need for a back-up power source. Thus, even if the power source voltage for the microcomputer 100 drops, the information already stored in the memory 64 thus far is held thereafter, even with no erasite of the information. When the microcomputer 100 is restarted after the microcomputer 100 has failed once, the information stored in the memory 64 thus far is stored continuously without power-on reset. In this case, only when the light signal of an deletion instruction transmitted from a handy terminal equipment 2 is received, is the information deleted.
