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.

6. The portable terminal capable of inputting three signals by one input key according to claim 5:

wherein when using the way of removing pressing on the pressed area and the area which is different from the pressed area, a letter, number or symbol allocated to the area where pressing is removed are inputted.

7. The portable terminal having at least one input key capable of inputting three signals according to claim 5:

wherein when using the way of removing pressing on either the first area or the second area after pressing the first area and the second area at the same time, a letter, number or symbol allocated to area where pressing is removed is inputted.

8. The portable terminal having at least one input key capable of inputting three signals according to claim 5,

wherein when using the way of removing pressing on the pressed area after pressing at least one area of the first area or the second area, an allocated letter, number or symbol different from letter, number or symbol which is allocated to the way of removing pressing on the pressed area and the area which is different from the pressed area and the way of removing pressing on either the first area or the second area after pressing the first area and the second area at the same time is inputted.

9. A portable terminal capable of inputting three signals by one input key:

at least one input key,
