Abstract

PURPOSE:To prevent a mark from being received by a reception side even when a marked original is transmitted again by taking the mark representing the end of transmission applied on the transmitted original as the tone which is not recognized by the light irradiated on the transmitted original at the time of reading the transmitted original. CONSTITUTION:The system is provided with a reading member which converts the picture information into an electric signal by accepting the light reflected by irradiating the light on a transmitted original 1 and reading the picture information of the transmitted original and a printing member applying a mark 2 representing the end of transmission on the transmitted original. The wavelength of the printing color to be applied on the transmitted original by the printing member is included in the wavelength area of the light to be irradiated on the transmitted original.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine used for communication of image information.

[0002]

2. Description of the Related Art Generally, a facsimile apparatus reads image information contained in the transmission document by irradiating the transmission document with light emitted from a light emitting element and photoelectrically converting reflected light with a light receiving element. It is equipped with a reading member such as an image sensor for taking it out as an electric signal, and a printing member such as a stamp for marking a mark indicating that the transmission is completed (transmitted) on the transmitted document after transmission. By transmitting the converted image information by wire or wirelessly, the image information is communicated with a distant point. In the reading member of the conventional facsimile apparatus, the light emitted to the transmission original for reading the image information is usually yellowish green with a wavelength of about 570 nm, while the printing member shown in FIG.
As shown in FIG. 5, the transmitted mark 2 that is marked at a predetermined position on the transmission original 1 to confirm that the transmission is completed after the transmission of the image information written on the transmission original 1 has a wavelength of about 700 nm or more. It was done with red or black ink.

The mark attached to the transmission original to indicate the completion of the transmission is provided to prevent transmission errors such as non-transmission and duplicate transmission on the transmission side. When transmitting, the transmitted original is to be provided to the facsimile apparatus a plurality of times, and the transmitted original is provided with the mark each time it is transmitted, and at the time of the second and subsequent transmissions, the mark provided at the previous transmission is corrected in advance. It is necessary to conceal with liquid etc. That is, when the transmission completion print is left as it is and the transmission is performed again, in the reading member, the wavelength of the light irradiated for reading the image information written on the transmission original and the wavelength of the color of the mark are completely different. Therefore, there is a problem in that the mark is also recognized and read as image information of the transmission document and is transmitted to the receiving side.

Further, because of the problems described above, the above-mentioned mark is generally provided in a small character in a conspicuous place in the corner of the transmission document, and even if the mark has been transmitted, the mark is missed. There is also a problem in that the same document is sent again easily. According to the present invention, the above-mentioned mark is provided in the facsimile apparatus by setting the mark indicating the completion of transmission, which is applied to the transmission document after transmission, to a color tone that is not recognized by the light emitted to the transmission document when the transmission document is read. The purpose is to prevent the receiving side from receiving the mark even if the original is retransmitted.

[0005]

In order to achieve the above object, the present invention provides the above-mentioned image information by irradiating the transmission document with light and receiving reflected light, and reading the image information of the transmission document. In a facsimile apparatus equipped with a reading member for converting the electric signal into an electric signal and a printing member for marking a transmission completion mark on the transmission original after transmission, the wavelength of the color of the printing printed on the transmission original by the printing member is changed. The reading member is configured to be included in the wavelength range of the light emitted to the transmission original.

[0006]

With the above structure, when the transmission original having the mark indicating the completion of transmission is retransmitted, when the transmission original is irradiated with light for reading image information, the wavelength range of the light is transmitted. Contains the wavelength of the color of the mark indicating the completion of transmission, the light radiated to the part of the mark indicating the completion of transmission is reflected to the extent that it is recognized as a part in which no printing as image information is printed. Will be done. Therefore, the mark indicating the completion of the transmission is not read and is not transmitted to the receiving side.

[0007]

EXAMPLES The features of the present invention will be described below in more detail by showing examples, but the present invention is not limited to the examples. The light emitted from the image sensor of the facsimile apparatus of the present embodiment to the original to be transmitted is yellow-green with a wavelength of about 570 nm, while the color of the transmitted mark marked by the stamp is yellow-green, which is substantially the same as the wavelength of the above-mentioned emitted light. did.

When a document is transmitted to a general-purpose facsimile device using the facsimile device configured as described above, a yellow-green transmitted mark is marked on the document when the first transmission is completed, and this transmission is continued. The manuscript marked with the completed mark was retransmitted as is. As a result, only the characters written on the transmitted document were printed on the received document, and the transmitted mark was not printed.

In the present invention, the same result as above can be obtained even if the wavelength of the irradiation light for reading the above-mentioned original is red of about 720 nm and the transmitted mark is red of the same wavelength as the irradiation light. . Further, in the present invention, it goes without saying that the irradiation light may be light having a composite wavelength and may be a transmitted mark of a color having a wavelength similar to that of the composite light.

[0010]

According to the present invention, even if a document on which a mark indicating that it has been transmitted is printed is transmitted as it is, the characters on the document are not transmitted to the receiving side without the mark being transmitted.
It is possible to satisfactorily send designs, photographs, etc. Therefore,
Even when the same document is transmitted to a plurality of places, it is not necessary to perform the process of deleting the mark indicating that the document has been transmitted.

Further, according to the present invention, even if the mark indicating that the data has been transmitted is transmitted as it is, the mark is not transmitted to the receiving side. Therefore, the mark can be easily recognized by the transmitting side on the transmitted document. It is possible to print at various sizes and positions, and it is possible to significantly reduce the oversight of transmitted data.
