Abstract

PURPOSE:To reduce times required for transmitting inputted original, by detecting positions where information to be encoded in two tone and that to be encoded in multitone are divided from each other, and by changing over outputs of the reading means. CONSTITUTION:When a reading device of a reader 1 reaches a position shown by the line A, operators set the count-up value in such a way that a counter contained in a position detector 5 delivers a count signal. When the reader 1 is reading the left hand side of the line A where only a seal impression exists, the detector 5 does not deliver the count-up signal, and a switch 4 is changed over to a terminal at a multitone encoder 2 side, and then, the output of the reader 1 is given to the multitone encoder 2. When the reading position of the reader 1 reaches the line A, the count-up signal is delivered from the reader 1, and the switch 4 is changed over to the other terminal at a two-tone encoder 3 side, and then, the output of the reader 1 is given to the tow-tone encoder 3.
