PURPOSE:To directly indicate coordinates on a picture display by displaying the same picture as the picture display on the compact display of an operating part, and transmitting it by operating pointing to the compact display. CONSTITUTION:An operating part 1 is provided with a pen 7 for point, and at the time of indicating the surface of a display 5 with the pen 7, the coordinates on the display 5 are indicated, and the coordinates correspond to the coordinates(X, Y) of a picture display 6. As the detecting means of the coordinates of the display 5, for example, a transparent rubber whose electric resistance is changed according to pressurization is adhered to the surface of the display 5, and the decrease of a voltage is measured around. Coordinate values detected as mentioned above are transmitted from a light emitting part 3 to a receiver 2, and the pointing of the coordinates of the receiver 2 is operated. Thus, the coordinates on the picture display 6 can be directly indicated. |
