Abstract

PURPOSE:To enable to display the required character on the display tube by touching the light pen, by locating LEDs in the form of matrix on the input information board and by making them correspond to the character/graphic converter. CONSTITUTION:If picture information is editted by displaying the character or graphic located on the points X1 and Y1 on the picture tube of a CRT16 in addition, when a light pen touches the position of X1 and Y1, detection signal of a light pen 14 is input to a compound synchronizing signal circuit 7. Then, cursor is displayed on the position of X1 and Y1 and simultaneouly, scanning signal output to a CRT16 from the compound synchronizing signal circuit 7 is stopped. Next, the light pen contacts the position of the desired character or graphics of a light pen input information device 13, the position signals X1 and Y1 are counted by counters 11 and 12. Then, this velue is input to a character/ graphic converter 15 and is converted into a character signal or graphic signal. After that, the signal is input to the compound synchronizing signal circuit 7 and the scanning signal is input again to the CRT16 from the compound synchronizing signal circuit 7 to display the character or image on the CRT16.
