PROBLEM TO BE SOLVED: To improve the difficulty to input because keyboard-shaped input buttons of electronic equipment or a personal computer are monochromatic and single in shape such that input button areas for the right hand and left hand are not clear, and to allow even a person having poor eyesight to easily input Japanese. SOLUTION: Color, pattern and shape are added to keyboard-shaped input buttons of electronic equipment or a personal computer in a projecting or recessed manner, and color, pattern and a projecting or recessed shape are provided in the index finger input button of the right hand (a boundary to an input of the left hand). Further, input bases are arranged at four places of input buttons FAJ+, having a base for the whole characters. COPYRIGHT: (C)2011,JPO&INPIT
