<p>PURPOSE:To transmit data such as a hand-written character or a hand-written figure, etc. at once by using a radio signal by obtaining the coordinate value of a designated position according to an AC signal detected from the respective loop coils of X direction and Y direction, and converting it into the radio signal and transmitting it toward an external part. CONSTITUTION:A radio wave is transmitted and received between one loop coil among the many loop coils of X direction and Y direction of a tablet 1, and the tuning circuit 25 of a position indicator, and this is repeated for all the many loop coils of X direction and Y direction. Then, at that time, the coordinate value of X direction and Y direction of the designated position based on the position indicator is obtained from an obtained induced voltage, and the coordinate value and the data based on said coordinate value, etc. are indicated on a display 3, or are converted into a radio signal and transmitted to other device by a radio communication device. Thus, the optional character or the figure, etc. can be highly precisely inputted by only operating the position indicator on the tablet 1, and an inputted result can be immediately transmitted to other device after converting it into the radio signal.</p> |
