Abstract

A touch press key inputting device includes: a plurality of character keys 21˜32 with at least 2 characters displayed on the surface of each key; an input judging means 72 for sensing the character keys touched and the first touched points in the area of the character keys, performing a movement longer than a specified length originally touched, and judging a moving direction in touch press inputting; a character selecting and outputting means 73 for selecting and outputting the characters displayed in the moving direction, corresponding to the moving direction judged by the input judging means, relative to the reference positions of the character keys. Since the characters on the positions are selected and output corresponding to the touch press inputting operations of the characters displayed on the key surfaces of respective character keys 21˜32, the inputting operations can be directly sensed and easily assured, and the inputting operability is improved.
