<p>PURPOSE:To improve the operability, by adopting a system inputting the setting of time of a program timer with a shift switch and a numeric shift switch. CONSTITUTION:A keyboard 4 inputting information required for operation of the program timer is constituted with switches inputting which program among programs stored in a memory 2 is to be selected and executed, and two on/off switches 41, 42 for inputting the set time, and these signals are led to a CPU1 via an input port 5. The digit is shifted up or down in the CPU1 by each depression of the switch 41. The numeral set in the CPU1 is shifted up (or down) by one digit each at each depression of the switch 42. That is, the numeral is designated as 0, 1, 2- in ascending order at each depression. Thus, while confirming the numeral displayed on a display device 6, the time data having a desired number of digit is inputted only with the operation of two switches 41, 42.</p> |
