Claim Text:
1. An electronic device, comprising a display unit that displays a letter/character; a touch pressing input unit including a plurality of keys arrayed in a matrix; the touch pressing input unit allowing touch-inputting a letter/character corresponding to a key touched by a user's finger; the touch pressing input unit allowing pressing-inputting a letter/character corresponding to a key pressed; and a microprocessor that manages a control of the display unit and the touch pressing unit to cause the letter/character input by the touch pressing input unit to be displayed on the display unit; and a touch input unit arranged at a pre-set location at a periphery of the touch pressing input unit, the touch input unit being able to touch-input a corresponding letter/character when the touch input unit is touched by the user's finger, wherein the microprocessor manages the control of the display unit and the touch pressing input unit so that, if a key is touched and pressed at the touch pressing input unit with the user's finger, a letter/character corresponding to the key pressed is displayed on the display unit, and so that, if a key is touched and released without being pressed by the user's finger at the touch pressing input unit, a letter/character corresponding to a key disposed at a position from which the user's finger has been released is displayed on the display unit; the microprocessor manages the control of the display unit and the touch pressing input unit to display a corresponding letter/character on the display unit when the user's finger has touched and released the touch input unit; the touch pressing input unit includes a display element configured to display a letter/character from one key to another; the touch input unit includes another display element configured to display a letter/character; the microprocessor manages the control of the display unit and the touch pressing input unit so that, when a user's finger has touched a key for a pre-set time, an input navigation corresponding to the touched key will be displayed on the corresponding display element and on the other display element, the touch pressing input unit comprises: from one key to another, a key member arranged on a substrate via a hinge exhibiting repellant elasticity, a dome-shaped contact, a fixed contact and a tactile sensor; the dome-shaped contact and the fixed contact come into contact with each other when the key member is pressed such as to detect the pressing of the key; and the tactile sensor is mounted on the key member to detect touching by the user's finger.
