PROBLEM TO BE SOLVED: To provide an information processor which can check the residual capacity of a battery freely even in the case of using a battery of such property that there is little voltage change to the usable electric charge of the battery. SOLUTION: In an information processor, which has a storage part 2 for storing data, an IC 3 for clock for timing, a central processor 1 for processing data, a power source 5 for supplying operation voltage at normality, and a battery 6 for backing up the storage part and the IC for timepiece at the time of breakage of power, a backup time processor 1b, which times when the storage part and the IC for a clock are backed up by the battery, and an electric quantity computer 1c, which computes the residual charge of the battery from the backed-up time are provided. |
