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 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.

摘要： A coordinates input apparatus which detects vibration, inputted by a vibration-input pen, by a plurality of vibration sensors provided on a vibration-transmitting tablet, and derives coordinates of a vibration-input point based on vibration transmitting time on the vibration-transmitting tablet. The vibration-transmitting tablet comprises a glass substrate and two sheets of resinous film laminated on the glass substrate. The two sheets of resinous film are laminated on both surfaces of the glass substrate in an orientation such that the stretched directions of the resinous film differ for 90 degrees. By this, a vibration-transmitting tablet where sheets of protection film are laminated, and a coordinates input apparatus which minimizes the changes in vibration propagation velocity depending on the propagation directions, are realized.

A plurality of vibration detection units are provided for detecting vibrations transmitted through the vibration transmission plate, and a determination unit determines coordinates of the vibration generation source by measuring time periods of propagation of vibrations through the vibration transmission plate from the vibration generation source to one or more of the vibration detetion units. Further, the vibration transmission plate and the plurality of vibration detection units are provided such that bisectors of angles made by two line segments each connecting two opposing vibration detection units from among the plurality of vibration detection units coincide with axes of anisotropy of the vibration transmission plate.
