摘要： There is provided a coordinates input apparatus to decide input coordinates from the propagating times of the ultrasonic vibrations on the vibration propagating plate made of a transparent glass plate input tablet. This apparatus comprises: a vibration pen to generate a vibration; an input tablet to which the vibration pen touches and which propagates the vibration generated; vibration sensors, attached to the input tablet, for detecting the vibration generated by the vibration pen and propagated by the input tablet; a measuring device to respectively measure two periods of time from the vibration input by the contact with the input tablet by the vibration pen until the leading and trailing zero-cross timings of the peak wave among the vibration waves detected by the vibration sensors; a calculating circuit for calculating the vibration propagating distances from the vibration input point on the input tablet to the vibration sensors on the basis of the two periods of time until the leading and trailing edges of the peak wave among the vibration waves measured by the measuring device and the vibrating velocity; and a controller to obtain the position coordinate values of the vibration input point on the input tablet by the vibration propagating distances from the vibration input point to the vibration sensors.
