PURPOSE:To input surely and intutitively the information by inputting frequency information and time information to input both the frequency and time information to a sounding circuit deciding the height and length as the coordinate information of a coordinate input device. CONSTITUTION:The information representing the height and length of the voice indicates selectively a coordinate input plane of a coordinate input device 2 comprising a pressure sensing tablet device and the X coordinate information and the Y coordinate information are inputted to the sounding circuit 1 as a digital data. The circuit 1 converts the frequency and time information relating to the inputted voice into a voltage value by D/A converters 15, 16. Each information is inputted to a VOC11 and a multivibrator (MMV) 12 via sample and hold circuits SH17, 18, and a gate signal generated by the MMV12 outputs a frequency signal outputted by the VOC11 to a speaker 3 from an amplifier 14 via a gate circuit 13. |
