2. Description of the Related Art For creating a document in a company or the like, the emphasis is shifted from a method of directly writing on paper by using a writing instrument by hand to a method of writing on a display device by using a personal computer using a personal computer. ing. When a personal computer is used, the user does not directly write on the display device, but writes it electronically in the storage means and perceives the content by the display device. I get the impression that I am directly writing in. Documents created by a personal computer have the advantage of being easy to copy, search, and transfer because they are written electronically in a memory.

When two users at different places exchange documents, conventionally, either one of the two users creates a document in an electronic memory and once prints it on a sheet of paper with a printer device. In general, a facsimile machine scans an image on a sheet into an electric signal by photoelectric conversion and communicates with the facsimile machine of the other party.

A method of directly transmitting an image of a document created on an electronic memory from a communication interface board is to print the image of the document on a sheet of paper by a printer and pass the image of the sheet of paper through a photoelectric conversion means of a facsimile apparatus. In comparison with the method of converting the electric signal into an electric signal and transmitting the electric signal, a higher quality image is transmitted. Such image information is often stored as a file in a large-capacity disk storage device for efficient use, and is often centrally managed by the OS of the computer main body.
