Abstract

PURPOSE: To realize the Chinese character input tablet of a simple structure by receiving the signal from two vibrating members and the signal from the fixed pick up and operating them and determining the coordinates of the inputting pen.
CONSTITUTION: Ultrasonic wave is alternately propagated in a plane on the plane board 1 from the vibrating members 2 and 3 disposed on the two adjacent sides situated on the even plane board 1, the inputting pen 4 is contacted on the plane board 1 to detect the ultrasonic wave. The propagating time difference from the start of vibration of the vibrating members 2, 3 to the detection thereof is counted by 12, 13 to determine the input coordinate of the input pen 4. The fixed pick up 5 is disposed at an end of the opposing side to the vibrating members 2 and 3, the signals from the vibrating members 2, 3 and the signal from the pick up 5 are received and operated by the operation circuit 16 to determine the coordinates of the pen 4. Thus, constantly fixed absolute coordinate is obtained and the Chinese character input tablet can be realized by the simple structure.
