PURPOSE:To set easily the same time as previously set time by loading set time data from a set time storage device to a timer device. CONSTITUTION:The one-time timer part 19 is reset with the output signal of a comparator 23 and its set time is erased. A subtractive timer part 20 varies its time on the start of subtraction and its set time is erased as well. Time set switches 3a-3d, however, are operated while a one-time timer switch 5 or 6 is pushed, and then the set time is stored in memory 25 or 26. For the purpose, the set time data stored in the memory 25 or 26 is loaded in the one-time timer part 19 or timer part 20 by operating the daily timer switch 4 or 5, i.e. loading operation. Therefore, when the same timer reservation time as before is set, the need for the troublesome operation of the switches 3a-3d for time setting is eliminated and the time setting is performed by the simple loading operation, i.e. only by pushing the switch 5 or 6. |
