Abstract

PURPOSE:To improve the efficiency of the transmission and reception for the picture information of plural originals having the same constant pattern, by dividing an original into the constant pattern and other picture areas and transmitting and receiving them independently. CONSTITUTION:An original slip A is read by a scanner 1 at the transmitting sideIand stored in an original slip storing circuit 2. At the same time, the fact that the read-out data belongs to the slip A is informed to the receiving side II. The data received at the side II is decoded by a decoder 8 and then stored in a slip storing circuit 9. After this, a slip B with which the filling-up is over is read by the scanner 1, and the format of the slip A is deleted through a data extracting circuit 4. Then only the written information is transmitted. At the side II, the received data and the original slip data given from the circuit 9 are synthesized 10 and recroded 11. Accordingly, when numbers of picture having the same constant pattern are transmitted, it is sufficient to transmit and receive only the necessary data excluding the constant pattern.
