Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pen input device capable of attaining hand-written pen inputs from plural operators by inexpensive constitution. SOLUTION: Input pens 1, 2 are respectively provided with ultrasonic senders, an ultrasonic receiving part 30 having plural ultrasonic receiving elements 31a to 31c three-dimensionally arrayed and capable of receiving ultrasonic waves transmitted from the senders is arranged on a prescribed position and the pointing position information of the input pen 1 or 2 on 1st coordinates fixed on the array positions of the elements 31 is computed by an arithmetic processing part 40 based upon the receiving outputs of the elements 31. Simultaneously, the processing part 40 discriminates whether a pointing position corresponding to the computed pointing position is included in a 1st input area 10 or a 2nd input area 20 separated from the area 10, transforms the pointing position information into 1st position information indicating the position on the coordinates fixed on the 1st input area 10 or a position on the coordinates fixed on the 2nd input area 20 in accordance with the discriminated result and controls the display of a display means 50 correspondingly to the transformed position information.
