Character input system
First Claim
Patent Images
1. A character input system, comprising:
- input means including nine touch-activated input sections arranged in a 3×
3 matrix for generating a plurality of input signals; and
means for selecting between numeric and alphabetic character input modes;
numeral generating means for operating in the numeric character input mode to said input means when one of said input sections is touch-activated to generate a numeral code corresponding to one of the numerals 1-9; and
character generating means for for operating in the alphabetic character input mode to accept at least two input signals generated by touch-activating selected ones of said input sections including at least one of said input sections in the first row of said 3×
3 matrix, generate character codes corresponding to the alphabetic letters A-Z comprising;
means for temporarily storing said input signal generated each time that one of said input sections is touch-activated,means, responsive to the input signals, for determining that touch activation of said input sections for one character is completed in the alphabetic character mode, andmeans, responsive to said storing means and said determining means, for reading out said input signals stored in said storing means when said determining means determines that the touch activation for one character in said alphabetic character input mode is completed.

Abstract
A parallel operation in which two input devices of nine input devices disposed in a square arrangement of, for instance, 3×3, 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.
