Abstract: A facsimile apparatus is provided with changeover means that makes it possible to pass signals through or to bypass a coder, which encrypts transmission information, and a decoder, which decodes encrypted information that has been received. Whether or not a facsimile apparatus belonging to another party has an encrypting/decoding processing function is verified by a pre-procedure signal. If the other party's apparatus possesses an encrypting/decoding processing function, control is performed in such a manner that encrypting/decoding processing is applied solely to an image signal and a training-check signal transmitted before transmission/reception of the image signal, and encrypting/decoding processing is not applied to a procedure signal which accompanies transmission reception transmission/reception of the image signal.
