Abstract: PURPOSE:To prevent the transmission of a white sheet due to the set error of an original by issuing an alarm to an operator when code data amounts for one line of the original are smaller than a certain decided value at the time of reading the original. CONSTITUTION:A size (number of trasfer) between the leading address and the final address of a picture memory is set in a DMA 35. Then, an encoding LSI 34 is activated, a reader part 2 is activated, and the original for one page is read. Then, after the reading is ended, the value of a line counter 33 is read.
