Filed: 1986-09-30
Abstract: PURPOSE:To attain a one-to-one facsimile communication of information which requires confidence and to secure the secrecy of information by index-displaying only destination information of a received FAX male. CONSTITUTION:Destination information mentioned in the head page of the received FAX male is extracted and controlled. Only character picture showing the destination is displayed and the reception of the FAX male is indicated. If destination information addressed to oneself exists in the displayed character picture, ID information added to destination information is indicated and inputted, whereby the FAX male specified by ID information is selectively read from a picture memory and hardcopy-outputted. Consequently, the received male which is facsimile communicated is not printed out at the same time as receiving, it can be printed out only when a request from a user specified by the destination is received. Thus, the contents of the received male do not unwillingly leak to a third person. With using a FAX equipment which is shared with plural users, the one-to-one information communication in which confidence is secured is attainable.
