Abstract
Abstract A facsimile system comprises: an image memory for storing received image data and image data to be transmitted; means for detecting a remaining memory capacity in the image memory; means for storing document data of each of the received image data and the image data to be transmitted; means for enciphering at least a part of image data stored in the image memory upon detection of an insufficient remaining memory capacity by the remaining memory capacity detection means; means for recording the enciphered image data on a recording sheet together with the document data thereof; means for reading the recorded enciphered image data; and means for deciphering the read enciphered image data.
