Abstract
PURPOSE:To attain accurate coordinate input by measuring a vibration transmitting distance from time information up to leading and trailing zero crossing timing of a peak wave of a detecting signal waveform and determining the coordinates of an input point. CONSTITUTION:Vibration from a vibrating pen 3 is inputted to a vibration transmitting plate 8, transmitted as a plate wave and detected by three vibration sensors 6. Output signals from the sensors 6 are inputted to a waveform detecting circuit 9 and timing information necessary for the calculation of vibration transmitting time for the detection of coordinates is outputted to an operation control circuit 1. The circuit 1 finds out time values tp, t'p up to the leading and trailing zero crossing timing of peak waves of the detecting signal waveforms from the sensors 6, calculates a distance between a vibration input point and each sensor 6 by combining these time values and determines coordinate information from the distance information.
