ABSTRACT:
A parallel operation in which two input devices of nine input devices disposed in a square arrangement of, for instance, 3.times.3, are touched substantially simultaneously is performed at least once, so that a character code corresponding to the input signal is produced, and thereby character input is performed. Furthermore, in the present invention, by using an independent operation of a single input device together with a parallel operation of two input devices, and operating the input devices in a predetermined sequence, such as from top to bottom or in the sequence of the pen-stroke describing the character, a character code corresponding to the signal inputted by the operations is produced, so that character input is performed.
