Keyboard-type input apparatus

DETAILED DESCRIPTION The unique points in the present invention are that fifteen keys in the three-line and five-column are at least divided into the vowel sound area and consonant sound area to assign the vowel sounds and consonant sounds onto respective keys, and before explaining various embodiment in the present invention, it will have to be explained first that the fifteen keys are arranged in the three-line and five column state and the key latwistedt concept is originally reconsidered by the present inventors.
Referring to FIG.
1, there is shown the positions for the right fingers upon using the fifteen keys, in vertical three lines and horizontal five columns (the positions shown with the figures of 7, 8, 9 and 10 with circle in the drawing), which have a possible sphere for the fingers pressing smoothly the keys with the touch-typing by fingers of either the right hand or left hand except the thumb.
Upon considering pressing effectively in accordance with conventional way of typing, the right fingers on the key arrangement should be divided into the two columns in the left side assigned by the index finger and the three columns in the right side assigned by the middle finger, ring finger and little finger and the home positions of such the four fingers are divided onto the four keys of the figures of 7, 8, 9 and 10 with circle in the middle line.
FIG.
13 shows EASY TYPING ORDER of fifteen keys in vertical three columns and horizontal five lines.
As shown in FIG.
2, in the area of one index finger and the area including one middle, ring and little fingers, the finger positions on the middle line are the easiest typing area and the upper line is the second easiest followed by the lower line and furthermore as shown by figure in the figure, in each line the area of one index finger has 1 and 2 from the right of the figure and the area of one middle, ring and little fingers has 1, 2 and 3 from the left of the figure in easy typing order.
Furthermore, when four keys are added below the fifteen keys of vertical three columns and horizontal five lines (the lowest column) and pressed by one thumb, one thumb can be used in the area of the thumb as shown in FIG
