PURPOSE:To display digits to be changed at their setting easily and to simplify operation by turning on/off respective digits of a display device at the specification of a digit for which data are to be inputted and operating the data input of each digit only by a digit shifting key and a numeral key. CONSTITUTION:A pointer register 4 outputs a signal specifying only one digit of the display device 1. A flashing driving circuit 5 flashes and displays only the corresponding digit on the basis of the digit specifying output from the pointer register 4. The digit shifting key 6 is a key to shift the digit specifying output of the pointer register 4 horizontally. A numeral signal generating circuit 7 is a circuit outputting numerals 0 through 9. The numeral shifting key 8 shifts a numeral signal outputted from the numeral signal generating circuit 7 by +1 or -1 for every operation. |
