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 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： In the coordinate detection of resistive film system, detection of the coordinates of simultaneously designated two points is made possible. On a touch panel composed of two conductive films, whether input is made in a point or simultaneously at two points is judged by a current monitor. Simultaneous inputs at two points decrease the apparent resistance of the conductive film, and can be detected by an increase in the current. If the input of a point is identified, the coordinate data of the input point are retained as latest coordinate data in a RAM. If simultaneous inputs at two points are identified, coordinate data are obtained from the coordinate data retained in the RAM and from the potentials in the x and y directions, obtained from two conductive films constituting a touch panel, through amplifiers, and are outputted, together with the coordinate data retained in the RAM, as the coordinate data of the two points.

摘要： A coordinate input apparatus having a stable and good input sense irrespective of different input conditions such as a vibration input position, a pen pressure and a pen angle. The coordinate input apparatus acquires an input coordinate in accordance with a delay time required for vibration input from a vibration input pen to a vibration propagation plate to reach a vibration sensor. A controller of the apparatus drives the vibration input pen at a first drive level. A window signal generator of the apparatus generates a window signal indicating that a significant signal was detected, when the level of an envelope detected from a signal supplied from the vibration sensor exceeds a detection threshold value. In accordance with the window signal, delay times tp and tg are acquired. A level discriminator of the apparatus judges whether the level of the envelope exceeds a discrimination threshold value. If it is judged that the level exceeds the discrimination threshold value, the controller drives the vibration input pen at a second drive level lower than the first drive level to acquire the delay times tp and tg.
