Abstract

PURPOSE:To transmit a pattern of high accuracy by a simple device, by carrying out the detection of position for both a recording pen and an input pen by means an exactly same means and accordingly realizing the use of a tablet having the inferior linearity after a conversion of position to eliminate a compensating circuit after a conversion of position. CONSTITUTION:A device that uses the electric field phase detecting method, etc. is provided to an input tablet 1 to detect the position of an input pen 2, and the position detection signal of the pen 2 is supplied to a drivng circuit 8 via a transmission line 4. At the same time, a position detecting device which is exactly equal to the tablet 1 is installed to an output surface 5 containing a recording pen 6 to perform the detection for the position of the pen 6. This position detection signal is supplied to the circuit 8, and a coincidence is always secured for the position detection signal between the pens 2 and 6. Then a drive motor 7 of the pen 6 is driven by the output of the circuit 8. Thus a tablet having the inferior linearity after a conversion of position can be used to eliminate a compensating circuit after a conversion of position. In such way, a pattern of high accuracy can be transmitted.
