摘要： It is an object to provide a portable coordinates input apparatus which can be manufactured at low costs. An input pen applies a voltage to a desired position in a coordinate input area on a vibration propagating plate having a piezoelectric performance and having a first surface including the coordinate input area and a second area that faces the first surface. A vibration generated by the voltage is detected as an electric signal by a vibration detecting electrode arranged out of the coordinate input area.

摘要： A high-precision coordinate input apparatus having a small circuit construction. A vibrating pen transmits vibration onto a vibration transmitting tablet, then vibration sensors provided at corners of the vibration transmitting tablet detect the vibration. One of the vibration sensor is used as a reference sensor. Time difference between vibration detecting timing by this reference sensor and detecting timing by one of the other sensors is measured. This measurement is performed on all the vibration sensors with respect to the reference sensor. The obtained time differences are converted into distance differences for calculation of the coordinates of the position in which the vibration has been generated. The vibrating pen has a power source and it operates independent of the apparatus main body. The vibrating pen changes its frequency of vibration in accordance with the voltage of the power source. The apparatus main body captures this change in the vibration frequency and obtain the state of the vibration pen power source.

摘要： A distance measuring device is capable, even utilizing the Lamb wave with velocity fluctuating from device to device, of easily setting an approximate wave velocity and of effecting precise distance calculation even with such approximate wave velocity. There is employed a system of measuring the thickness d of the wave transmitting plate, then determining the group velocity Vg of the Lamb wave from the measured thickness, then determining the phase velocity Vp of the Lamb wave from the plate thickness d and the frequency f of the Lamb wave, and deriving the distance from Vg, Vp and the arrival delay time of the Lamb wave.

摘要： When vibration is entered on a vibration transmitting tablet, the vibration is sensed by vibration sensors attached at four corners of the tablet. When this is done, a time delay from entry of the vibration to detection thereof is measured, and the distance between each sensor and the source of the vibration is calculated in dependence upon the time delay. At this time the vibration sensors also sense reflected waves resulting from reflection of the vibration at the end face of the tablet. The larger the angle of reflection, the greater the magnitude of the reflected waves sensed. Accordingly, sensors most likely to sense reflected waves are excluded from calculation, and coordinates are calculated based upon vibration sensed by the remaining sensors only. As a consequence, a discontinuity in coordinates occurs at the boundary of a region decided by whichever of the sensors are excluded. For this reason, a weighted mean is computed of a set of coordinates calculated based upon data obtained from a set of a plurality of sensors, and the value of the weighted mean is adopted as the coordinates sought.
摘要翻译： 当在振动传送片上输入振动时，通过安装在平板电脑四个角落的振动传感器来感测振动。 当这样做时，测量从进入振动到其检测的时间延迟，并且根据时间延迟来计算每个传感器与振动源之间的距离。 此时，振动传感器还感测由于在片剂的端面处的振动的反射而产生的反射波。 反射角越大，感测到的反射波的幅度越大。 因此，最有可能感测反射波的传感器从计算中排除，并且基于仅由其余传感器感测到的振动来计算坐标。 因此，坐标的不连续发生在由排除了哪个传感器的区域决定的区域的边界处。 为此，计算基于从一组多个传感器获得的数据计算的一组坐标的加权平均值，并且采用加权平均值作为所寻求的坐标。

A coordinate output form includes at least an absolute coordinate output form in which calculated coordinate values are directly output, and a relative coordinate output form in which the differential values between the calculated coordinate values and predetermined coordinate values are output. The value of the first axis of the calculated coordinate values is compared with a predetermined value. It is determined whether the coordinate values of the second and third axes of the calculated coordinate values fall within a predetermined range. The calculated coordinate values are output in a coordinate output form determined on the basis of the comparison result and determination result.
