Abstract

PURPOSE:To raise the operating property, by constituting so that a year data can be updated automatically by updating the year data of a memory area when a month data of a clock circuit is smaller than a month data of the memory area. CONSTITUTION:On magnetic memories 3, 4 of an electronic apparatus which has a clock circuit 14 for counting a month, day, hour and minute, and executes a necessary control operation by reading a data from the magnetic memories 3, 4, a memory area for storing a data of a year, month, day, hour and minute is provided. In this state, when an electric power supply is turned on, a month data of said memory area is compared with a month data of the clock circuit 14, and a year data stored in the memory area is updated by one year when the month data of the clock circuit 14 is smaller than the month data of the memory area.
