Abstract:
PURPOSE:To display a date existing in a calendar despite an erroneous input of data and to eliminate the second input of a user, by displaying the maximum value of the date existing in the calender to a display device in case the supplied date does not exist in the calendar. CONSTITUTION:A random access memory 17 stores the information fed by a key input means 3 as well as information on arithmetic results, dates, time points, etc. An arithmetic circuit 18 containing an accumulator and an arithmetic unit performs the operation of a processor 4. A driving circuit 19 converts the signal given from a random access memory 16 into a form suited to the driving of a display device 2. If the supplied month is larger than 13, the month is corrected to December for display. When the supplied date exceeds the last day of the month supplied precedently, the date is corrected to the last day of the present month to be used as an input data. Then the corrected date is displayed at the display device 2.
