PURPOSE:To input the finger picture of either finger of a right hand and a left hand by arranging finger guides at both a right and a left sides. CONSTITUTION:The finger guides 2a, 2b are arranged at the right side and the left side on the finger contact surface of a prism 1. Besides, the finger guides 2a, 2b are set so that their one sides at the sides along which the finger is placed are parallel with the longitudinal direction of the prism 1, and in addition, this direction is adjusted so as to intersect the scanning direction of a television camera 4 at right angles. Thus, since the finger guides are arranged at both the right and the left sides on the prism, either finger of the right and the left hands can be selected freely and placed, and the finger picture of either finger of the right and the left hands is inputted. |
