DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device capable of communicating color and monochrome images.

[Prior Art] Conventional facsimile machines are configured so that original images at the time of transmission and reception can be made into hard copies on paper using a printer such as a thermal printer, an inkjet printer, or an electrostatic printing printer. .

[Problem to be Solved by the Invention] Therefore, in the above conventional example, the original image is output only as a hard copy from the printer, so if you want to check the original certified at the time of transmission, you must print it out using the printer. However, the disadvantage is that paper is wasted.

Also, when receiving documents, all documents are output from the printer.
This has the disadvantage that unnecessary information is also output, resulting in wasted paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile machine that can visually confirm image information without wasting paper.

92), an operation command is output to the printer interface 104, raw image data is transferred from the page memory 109, and is output to the scanner interface 103 via the printer interface 104 to obtain an image of one page (5193.5194).

Note that in the above embodiment, when transmitting a monochrome image, the color/monochrome conversion unit 202 converts Y from RGB data.
A signal is generated and this is used as black and white data, but instead of generating a Y signal in this way, it is also possible to select any one of the RGH data and use it as black and white data. , the color/black-and-white converter 202 is not required, and the circuit configuration of the scanner interface can be simplified. Note that with this configuration, if you want to send a color document in black and white, there is a possibility that you will not be able to obtain a proper black and white image. It is possible to perform processes such as copying a document, creating a black and white document, and re-sending it. However, in reality, such cases are considered to be rare.

Furthermore, as another embodiment, instead of using a hard disk as the image storage memory, a semiconductor memory such as a DRAM or a magneto-optical disk may be used.

It is also possible to eliminate the page memory 109 for storing raw images and to perform all image transfer from the image memory (hard disk).

Furthermore, when reading a document, it is also possible to directly transmit the read image from the CCU without storing it in the image memory. Also, when reading a document, two (1) raw documents can be stored in one image memory.

[Effects of the Invention] As described above, according to the present invention, received images can be visually recognized without wasting paper by displaying received images page by page or page by page continuously on a display device. It can be carried out. For images that require hard copies, by selecting printout in page units or in units of communication, it is possible to print out only the necessary images and eliminate unnecessary hard copies.
