摘要： Vibration applied to a tablet is sensed by a sensor provided on the tablet and a time delay from generation of the vibration to the sensing thereof is measured, whereby distance from the vibration source to the sensor can be measured. If the vicinity of the leading edge of the envelope of registration is sensed when sensing the vibration, the effects of reflected waves from the periphery of the tablet are reduced. To this end, the envelope is differentiated to detect an inflection point. The peak gain frequency of the differentiating circuit is greater than the frequency of vibration generated by the vibration source. As a result, the phase of the output signal produced by the differentiating circuit is advanced by about .pi./2 with respect to the phase of the input signal, thereby making it possible to sense vibration more quickly.

摘要： Some components of a vibration input to an input guarantee region on a vibration transmission plate directly reach a vibration sensor, but some other components are reflected by the end portion of the vibration transmission plate, and then reach the vibration sensor. A vibration suppressor is attached to a peripheral edge of the vibration transmission plate, and is located along the path of the vibration reflected by the end portion of the vibration transmission plate to the vibration sensor. Since the vibration sensor is attached to a corner portion of the vibration transmission plate where no vibration suppressor is attached, a decrease in coordinate detection precision caused by reflected waves can be suppressed, and a compact apparatus can be realized.

摘要： A coordinate input apparatus according to the present invention eliminates distortion caused by interference of a asymmetrical plate wave with an asymmetrical plate wave from the vibrations which are detected after they have been propagated in a vibration transmitting member and performs a highly accurate position coordinate detection. The vibrations of a pen which is brought into contact with the vibration transmitting member are detected by sensors provided on both the front and rear surfaces of the vibration transmitting member to determine a coordinate of a position where the vibrating pen has been brought into contact. At that time, the vibration sensors mounted on the front and rear of the vibration transmitting member in an opposed relation detect vibrations on the two surfaces of the transmitting member. The signals which are detected by each pair of front and rear sensors represent vibrations in which the asymmetrical plate waves having the same phase and the 180.degree. out-of-phase asymmetrical plate waves are superimposed on top of one another. The signals of the two sensors are input to a differential circuit. A resultant differential signal is input to a signal waveform detecting circuit. Since the differential signal is a signal in which the asymmetrical waves are cancelled with each other and in which the asymmetrical waves are amplified by twice, reduction in the vibration detection accuracy which is caused by distortion of waveforms can be prevented.

摘要： Oscillation applied to a tablet is sensed by a sensor on the tablet and a time delay from generation of the oscillation to the sensing thereof is measured, whereby distance from the oscillation source to the sensor can be measured. If this distance is measured for each of a plurality of different sensors, the position of the oscillation source on the tablet can be determined. The measured delay time includes not only time for transmission through the tablet but also an error. Accordingly, the delay time between the oscillation source and a sensor is not used as is, one of the sensors is adopted as a reference sensor and a difference in delay time between this sensor and the oscillation source is used to measure the distance between the oscillation source and each sensor. As a consequence, errors attributable to respective sensors are canceled out so that measurement precision is improved.

摘要： A vibration-transmitting tablet and coordinate-input apparatus at low prices, which enable to easily manage precision of vibration detection position. A vibration-input pen inputs vibration, generated by its vibrator, onto the vibration-transmitting tablet formed by polarizing a piezoelectric member in its thickness direction. When the vibration propagated on the vibration-transmitting tablet reaches four electrodes provided at predetermined positions of the vibration-transmitting tablet, electric signals based on the vibration are detected from the respective electrodes. A signal-waveform detector detects arrival of the vibration at the electrodes based on the electric signals. An arithmetic controller calculates coordinates of the vibration-input position based on arrival timings of the vibration. The arrangement of the electrodes on the vibration-transmitting tablet can be realized by etching, printing or the like, thus management of precision of vibration-detection positions can be much easier.
