Abstract: PURPOSE:To enable complicated setting of plural times of actuation time with limited actuation time data by processing the actuation time data of the specified day of which date and time are directly appointed, with the utmost priority, and then by processing weekly appointing data which appoints the specified month, with the second best priority. CONSTITUTION:Actuation time data is constituted of a set of year data YY, month data MM, day-of-week data W, time data XX and minute data ZZ. The actuation time data which is set at an actually existing month and date, actuates a timer as the time data indicates, by using the data as the data appointing the specified date. Among the actuation time data, a data of which date is expressed as DD = 00, is assumed to be a weekly appointing data of every specified month. In this case, the timer works at the same hour and minute of the same day, each week of the set month. Among the actuation time data, data of which month is expressed as MM = 00 and date, DD = 00, is assumed to be a weekly appointing data. Priority of the actuation time data is the highest in specified date appointing data and the lowest in the weekly appointing data. In other words, when a plurality of actuation time data exist in the same day and if there is a specified date appointing data, timer works according to the latter data.
