Abstract
PURPOSE: To provide a easy-to-see time display device permitting easy rewriting of time information by displaying the departure or arrival time or the like of transport means of each time zone stored in non-volatile memories according to desired time zones.
CONSTITUTION: When a time zone is selected through a keyboard, the time zone code is stored via input control circuit 15 to an input-output buffer 12. At the same time, the codes of the times, train names, etc. train kinds, etc. of that time zone are subsequently temporarily stored in the buffer 12 in the same manner, after which these are written via input control circuit 8 into a non-volatile memory 5 which is backed up by other power source even at the time of power interruption. If the circuit 8 is controlled similarly, the contenets of the memory 5 are transferred into a similar memory 6 and the schedules of weekdays and holidays are stored according to time zones. When these memories 5, 6 are addressed through the keyboard, the departure and arrival times and others of trains, etc. are displayed according to time zones by reading-out of the storage contents, thus the easy-to-see train time display, etc. permitting easy rewriting may be provided.
