Abstract

PURPOSE:To reduce the touching frequency of keys down to just one time and to select easily and with no error a character out of a character group, by successively changing the contents of the input characters by consecutively pushing a specific key and at the same time displaying the form of the above-mentioned change. CONSTITUTION:When the address of the position supplied from an input device 1 is supplied to an I/O control part 3, the part 3 starts a timer 5 to which an interruption is applied in a certain period of time and at the same time initializes and starts a position display part 2. With a consecutive push of a specific key, the part 3 informs the positionIof the first character of the character group corresponding to the relevant position to the part 2 and then transmits a signal to display the position II when an interruption is applied from the timer 5. When the key is released immediately after a display of the desired position, the part 3 decides the character corresponding to the final position display as an input character and fetches the corresponding input code out of a generating part 4 to transfer it to a CPU7.
