摘要： A coordinate input apparatus which can attain an accurate coordinate input operation, includes a sensor for detecting an input variation. The vibration is amplified, and an envelope detection circuit generates the envelope of the amplified vibration. A gate signal generation circuit receives the envelope and a second-order differential signal of the envelope generated by an inflection point detection circuit. The gate signal generation circuit attenuates the envelope and adds a predetermined offset to the attenuated envelope. The gate signal generation circuit compares the sum signal with the second-order differential signal to generate a gate signal. In the duration of the gate signal, a tg comparator detects, as a group delay time, a time up to the zero cross point of the second-order differential signal, and a tp comparator detects, as a phase delay time, a time up to the zero cross point in a predetermined order of a phase signal. An arithmetic control circuit calculates the coordinate position of a vibration input source on the basis of these delay times.

摘要： In a distance measuring device for calculating the distance from the arrival time of the Lamb wave, the thickness of the propagation plate and the frequency of the Lamb wave are optimized in relation to the material of the propagation plate in order not to deteriorate the precision of distance detection even in case an approximate wave velocity is used in the calculation. The plate thickness and the frequency are so selected, in relation to the plate material, as to minimize a function G(f, d) defined by:G(f, d)=Vg.multidot.Vp/{f(Vg-Vp)}whereinf: frequencyVg: group velocity of Lamb waveVp: phase velocity of Lamb waved: plate thickness.

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： In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a “CHR input pad” window to be opened.

摘要： An object of the invention is to provide a coordinate input apparatus which phase-shifts an input signal in accordance with temperature and corrects a phase shift due to a change in temperature, thereby performing coordinate input. A phase shift unit of a temperature phase shift circuit is constituted by connecting two thermistors having the same temperature characteristics and two capacitors having the same capacitance to constitute a bridge circuit. An output (Eout) has a gain of 1 with respect to an input (Ein) and is phase-shifted by tan.sup.-1 [(-2.omega.CR)/.+-.(1-.omega.CR).sup.2)], where R represents a value which exponentially varies in accordance with temperature. For this reason, the output signal can be phase-shifted in accordance with a change in temperature. When this circuit is applied to a coordinate input apparatus using an ultrasonic wave vibration, the phase shift of a vibration due to variations in temperature is corrected, thereby enabling coordinate input stable with respect to changes in temperature.

摘要： A coordinate input apparatus has an effective area in a vibration transmission member for inputting a vibration from a vibration generator and a computing unit that computes the coordinates of the position of the vibration generator on the basis of the delay time between the vibration generation and the detection of the vibrations by a vibration sensor. A vibration proof material is disposed in the periphery of the vibration transmission member to prevent the inputted vibrations from being reflected at the acoustic impedance boundary of the vibration transmission member. The vibration proof material is disposed so that the spacing between the edge of the effective area and the edge of the vibration proof material facing the effective area edge becomes larger with increasing distance along the effective area edge from the vibration sensor.
