    • A duplicating and ciphering device in which, in order to retain the privacy of the document to be transmitted, the individual units of the duplicating and ciphering device are constructed as a duplicating machine, and annexation possibilities for an electronic memory for storing the information taken from the scanner and for a coding mechanism for coding this information. Such device can be used as a duplicating machine as well as a ciphering device for coding information before entering it into a fax machine. It is also suited to again emit incoming, encoded information in clear text. A method for coding facsimile telecopies is included whereby in sending, the original is scanned and transmitted line by line and at the receiving end a similar copy true to the original is printed out. In order to prevent confidential information from falling into the wrong hands, the content of the digital transmitted information is coded. A memory stores several dot rows and a coding mechanism, which interchanges the sequence of the stored dot rows and/or alters the relative position of the dot rows. The decoding follows then through entering a password or a coding card, for example.
    • 一种复制和加密装置,其中为了保持要发送的文档的隐私,复制和加密装置的各个单元被构造为复制机器,并且电子存储器的并入可能性用于存储从 扫描器和用于编码该信息的编码机制。 这样的设备可以用作复制机器,以及用于在将信息输入到传真机之前对信息进行编码的加密设备。 它也适用于以明文形式再次发送传入的编码信息。 包括编码传真电视的方法,由此在发送时,原稿被逐行扫描和传输,并且在接收端,打印出与原件相似的类似的副本。 为了防止机密信息落入错误的手中,数字发送信息的内容被编码。 存储器存储几个点行和编码机制,其交换存储的点行的序列和/或改变点行的相对位置。 然后,例如通过输入密码或编码卡进行解码。
