PURPOSE: To precisely designate date and time by providing a data memory, which can store plural schedule data, and a selection part to select the schedule data from the data memory.
CONSTITUTION: In a data memory 9, the schedule data inputted at the time of an input mode are numbered for each schedule and stored as a pair of date data and memo data. The date data are stored with being further divided into negative data and the other data. A selection part 11 retrieves the schedule data, which are equipped with the date data corresponding to the date data stored in a date buffer 7, from the data memory 9 and stores the number of the schedule data in a data memory 12 to be selected. Thus, plural days can be made correspondent to one set of memory data and even negative data can be inputted. Then, the date and time can be precisely designated.
