PURPOSE:To enable an operator to know an event at its scheduled time without monitoring the schedule by attaining a constitution where a data processor detects the scheduled event at a time point near its scheduled time with the periodical monitoring of the registered schedule and outputs an alarm earlier than the scheduled time by the prescribed time. CONSTITUTION:A schedule register means 1 inputs the schedules to a data processor, and a schedule storage means 2 stores the input schedule data in such a way that can retrieve the starting time of the scheduled event and the alarm time. A scheduled time monitoring means 3 retrieves the schedules stored in the means 2 in each necessary period and decides whether a scheduled event exists or not earlier than the scheduled time by the prescribed time. If so, the means 3 instructs an alarm output means 4 to output an alarm. Thus an operator can know an event at a time point near its scheduled time even in the midst of the time when the operator is carrying out other tasks. |
