    Abstract: 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.

    Abstract: 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.

    Abstract: There is provided a highly precise coordinate input device not requiring a particular designating tool. A sheet, composed of a piezoelectric plate polarized in the direction of thickness, is superposed with a vibration transmitting plate, provided with vibration sensors in predetermined positions. The sheet generates vibration by a pulse signal generated by a sheet driver. When the sheet is pressed for example with a pen, the vibration is transmitted to the vibration transmitting plate from the pressed position, and is detected by the vibration sensors. A controller calculates the distance between the vibration input point and the vibration sensor, based on the delay time from the start of vibration to the detection. This operation is conducted for the plural sensors, and the coordinate is calculated from thus calculated distances.
