PURPOSE:To output graph with a simple printer, by converting the stroke signal of hand written character and graph into raster scanning signal through the use of digital memory with comparatively small capacity and outputting the graph on the journal printer. CONSTITUTION:First, after the opposing terminal is called out and line is set by using a telephone set 10, the transmission/reception of audio signal and graph is made with the audio graph signal transceiver circuit 9. Further, a graph or character is drawn on the input section 2 by using the input pen 3, and the coordinate information of video element constituted with the graph or character is produced from the data tablet 1 and input to the control circuit 7. The coordinate information from the control circuit 7 is delivered to the graph signal transmitter 8, the coordinate information is taken as the address information, and the bit information is written in the digital memory 6 with random access system corresponding to the production of the coordinates. Further, the stroke signal of hand written graph or character is converted into the raster scanning signal by using the memory 6 to print out the graph or character on the printer paper of the journal printer 4. |
