Abstract

PURPOSE:To improve the detecting accuracy of coordinates, by pressurizing contact the oscillator of an oscillation pen with an oscillation transmission plate by interposing fluid with high between them. CONSTITUTION:The coordinate of the oscillation pen 3 is detected by performing coordinate input by the oscillation pen 3 on the oscillation transmission plate 8 superposed on a display unit, and measuring the transmission time of an ultrasonic oscillation by an oscillation sensor 6 provided at a prescribed part on the plate 3. At this time, the ultrasonic oscillation from the oscillator 4 in the pen 3 is transmitted to the plate 8 via a horn part 5, and the oscillator 4 is pressurized contact with the rear part of the horn 5 by a pressurizing load (f) by a spring, etc. Furthermore, the sensor 6 is also pressurized contact with the plate 8 by the load (f), and also, grease 61 with consistency of around 190-390 is interposed between the oscillator 4 and the horn 5, and between the sensor 6 and the plate 8.
