摘要： Continuity of coordinates between areas of a coordinate input surface which is divided into a plurality of areas is maintained. In inputting "A, B, C" on a coordinate input plate, when an input operation is started from an initial point, area is determined as an input area, and vibration delay times are measured by using sensors, thereby calculating a coordinate value. When the input operation is continued up to a terminal point, the input point shifts to area. However, vibrations are detected by using the same sensors to calculate a coordinate value as long as the input operation is continuously performed. With this operation, since sensors are not changed for the respective areas, discontinuity of lines at the boundaries between the areas can be prevented.

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 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.

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.
