PORTABLE TERMINAL FOR INPUTTING THREE SIGNALS VIA ONE INPUT KEY, AND TEXT INPUT METHOD USING SAME
First Claim
1. A portable terminal capable of inputting three signals by one input key comprising:
- at least one input key; and
a plurality of sensors sensing electrical signals positioned below the input key, wherein signal values are allocated to the sensors respectively and the input key inputs three different letters, numbers or symbols by pressing the input key one time by the sensors allocated with the signal values.

Abstract
According to the present invention a portable input terminal may be described. The input terminal may permit inputting letters in a portable terminal, letters that may be inputted more quickly than in conventional inventions because the present invention is set in a way that three different letters, numbers or symbols can be inputted by pressing one input key one time. Three letters, numbers or symbols may be inputted through one key and a plurality of sensors may be arranged effectively. The inputting accuracy significantly improves over the prior art, avoiding inputting errors by applying and developing various kinds of inputting ways using all characteristics of the present invention.

5. A portable terminal capable of inputting three signals by one input key comprising:
-
at least one input key, a plurality of sensors sensing electrical signals positioned below the input key, wherein the center of the input key is set as a reference point, and based on the reference point a left side of the reference point is set as a first area and a right side of the reference point is set as a second area; and a letter, number and symbol are inputted by at least one way of removing pressing on the pressed area and the area which is different from the pressed area, removing pressing on either the first area or the second area after pressing the first area and the second area at the same time, or removing pressing on the pressed area after pressing at least one area of the first area or the second area. - View Dependent Claims (6, 7, 8)
