Abstract

PURPOSE:To prevent fingers from drifting from a home position due to the change in posture, etc., while keying, by providing a means for preventing a one finger of both sides of a boundary line goes across the boundary line and hits a key which is put in charge of other finger. CONSTITUTION:At the time of operating an input key group 2a in a keyboard 1, the forefinger, the middle finger, the third finger, and the little finger take charge of a key train 11 and 12, a key train 13, a key train 14, and a key train, respectively. Also, when each finger of the right and has been placed in a home position, a partition wall 16, a partition wall 17 and a partition wall 18 exist between the forefinger and the middle finger, between the middle finger and the third finger, and between the third finger and the little finger, respectively, and it is limited that each hand finger flows and moves to the right and left. Also, a side wall 20 prevents the forefinger from being separated to the left, and a side wall 21 prevents the little finger from being separated to the right. Moreover, a wall prevents each hand finger from flowing forward. In such a way, it is limited that the hand finger moves freely to the right and left or forward and backward, by which a blind touch can be executed without being separated from the home position.
