PURPOSE:To enable a timepiece to exhibit functions as a timetable, by displaying a time on the timetable a certain time before its actual time. CONSTITUTION:Times on a timetable are stored in RAM27 formed in a matrix of 24 rows by 60 columns and operating switch S1 makes an analog display of the timetable of every hour on display part 9. Then, the time required for the movement from a desired place to the station is set in time setting circuit 17. Adding circuit 21 adds the time of setting circuit 17 to the current time of minute counting circuit 4 and hour counting circuit 5 to assign the time of RAM via decoders 26 and 30 and when ''1'' is read out of RAM corresponding to the time on the timetable, sounding 38 is carried out. |
