PURPOSE:To throw away or correct a reading information signal of a part other than the surface of an original into a white level by providing a beginning end detecting means of the original, a tailing end detecting means and a signal extracting means for extracting only an image pickup information signal between the beginning and tailing ends of the original. CONSTITUTION:A reading information signal of the original and succeeding ends is read as all white ''0'' because a gate 16 is turned off in the read of the reading information signal from a buffer memory 14. That is, the reading information signal is brought to white ''0'' during the beginning to the tailing end of the original of reading of one line regardless of contents of the reading information signal, and the signal from the end of original to the end of reading of one line is brought similarly to white ''0''. This fact is the rewritting of information and the adoption or rejection of the information. While a device 10 reads the output for one line's share from a binary-coding circuit 8, a device 20 processes the reading information signal of one line read before as above and reads it and while the device 20 reads the next one line, the device 10 reads the reading information just before with the processing above. |
