Then a black picture element number count means 3 detects whether or not a black picture element is in existence in the unit of bytes and number of black photoelectric conversion elements is counted. Then number of black picture elements counted by a white paper page discrimination means 4 is compared with a preset threshold number thereby discriminating whether the page is white paper or not. When the page is not white paper, the page is sent to an opposite party by a transmission means 5. When the paper is white paper, the display to instruct whether or not the information is sent to, e.g. the operator is implemented and the transmission is started or the transmission is stopped by the instruction.
