PURPOSE:To delete an unrequired picture by marking a picture one a transmitted original, which is not to be transmitted, at a fixed position in specific color and by adding it as a control signal in transmitted data. CONSTITUTION:Marking on transmitted original 1A is detected sensor 5. Other pieces of picture information are read by image sensor 6. The picture information, read by sensor to be transmitted to the receiver, is amplified by amplifier 7 and then coded into binary codes by binary-coding circuit 8. This binary-coded picture information, when having marking detected by sensor 6, is stopped by gate circuit 9. Its detection signal is transmitted to the reception side under the control of control circuit 10. The receiving circuit, on the other hand, discriminates received information and a control signal is added to a picture with marking and then detected by code detecting circuit 13, so that it will not be printed out. |
