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： An influence by a vibration which is transmitted in the air is reduced, thereby preventing an erroneous detection of coordinates or a deterioration in a detecting precision. An elastic resin sheet is arranged on a coordinates input surface side of a vibration transmission plate so as to have a gap between the resin sheet and the vibration transmission plate and is fixed by an adhesive layer. When coordinates are inputted by a vibrator pen, namely, when a vibration is inputted, the resin sheet is warped by a writing pressure of the vibrator pen and the resin sheet comes into contact with the vibration transmission plate. Therefore, the vibration applied by the vibrator pen is efficiently transmitted to the vibration transmission plate. On the other hand, a vibration transmitted from the air is reflected by the boundary on both surface sides of the resin sheet and by the surface of the vibration transmission plate by a difference between acoustic impedances, so that the vibration entering the vibration transmission plate is remarkably reduced.

摘要： A shift of an input coordinate by a change in temperature in a coordinate input device is prevented. An arithmetic operation and control circuit 1 applies a drive signal to a vibration pen 3 and starts a timer. The drive signal applied to the vibration pen 3 is delayed by a delay circuit 12, which drives a vibrator drive circuit 2 to generate vibration. A delay time of the delay circuit 12 is shortened as a temperature rises and a sum time of the delay generated by the delay circuit 12 and a delay generated in the vibration pen 3 as the temperature changes is constant regardless of the temperature. As a result, a vibration propagation time measured by the timer represents a net propagation time plus a constant delay time regardless of the temperature. Thus, the stable coordinate input is assured regardless of the temperature.

摘要： A piezoelectric sensor for detecting elastic plate vibrations in an object such as the transmission plate in a coordinate input apparatus is prismatic in shape and is fixed to the surface of the object. The prismatic sensor is arranged so that it is parallel to the direction of propagation of the vibrations and has an electrode surface perpendicular to the surface of the object. The arrangement of the prismatic sensor permits the thickness of the object in which the plate vibrations propagate to be substantially reduced and reduces the manufacturing cost of coordinate input apparatus using the prismatic sensor.

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.

摘要： A coordinate input apparatus which can stably input coordinates at a high precision is provided. A vibration sensor is fixed to a vibration propagating plate by means such as an adhesion or the like. Electrodes are formed on both edge surfaces of the vibration sensor. One electrode is connected to the vibration propagating plate (its surface is made of a conductive material). Another electrode is connected to a conductive plate spring through an electrode leading member. The electrode leading member has a cylindrical portion to position a projecting portion to a center axis by setting a side surface of the vibration sensor to a reference has a relation adapted to be come into engagement with the vibration sensor. The plate spring presses the electrode leading member to the vibration sensor and is electrically connected to the vibration sensor. Since the position to extract a signal from the vibration sensor is positioned by setting the side surface of the vibration sensor to a reference, the signal can be stably extracted at a high precision.
