[Description of Characteristic Parts] Next, the characteristic parts of the image filing apparatus of this embodiment will be described. The image filing apparatus of this embodiment records an area surrounded by a marker printed on a document as an image document name and uses it as a document index.

FIG. 8 is an explanatory diagram showing a page of a document marked with a marker. In the figure, the “file device” on the first page of the manuscript 30 is surrounded by a marker 33. The marker 33 is written with a marker pen of a specified color,
Here it is red. When the document 30 consisting of five pages is placed on the document feeding device 101 and the start button is pressed, the image filing device conveys the document 30 on the document table glass surface 102 in order from the fifth page and scans for reading. . At this time, reading scanning is performed in the red erasing mode.

The read image data is stored in the core unit 2
It is digitized, sent to the file unit 5, and stored in the external storage device 6. The detection result of the color detection circuit is sent to the core unit 10 in addition to the image data. When the red marker color is detected, the core unit 10 outputs a scan command to perform the second reading scan.

In the second reading scan, only the image data in the area surrounded by the marker 33 is sent to the core section 10. The core unit 10 binarizes and sends it to the file unit 5, and the file unit 5 records it in the external storage device 6 as the image document name of the document being recorded.

If the red marker color has not been detected, the scanning is finished at the first reading and the conveyance command is output. When the next page is conveyed, a scan command is output and the reading scan is performed in the same manner.

In the manuscript 30 shown in FIG. 8, since no marker is written from page 5 to page 2, one reading scan is completed and only the first page is read twice.

In the first read scan of the two read scans, the marker 33 around the "file device" is erased, the image data of the entire page is recorded in the external recording device 6, and the second read scan is performed. Then, the image data of the area including the “file device” surrounded by the marker 33 is recorded in the external storage device 6 as the image document name.

The image document name is displayed at the time of retrieval and is used for narrowing down documents. When an optical character reading device (OCR) is added as an extended function, the character search can be performed by specifying "file device".

As described above, the marker 33 is erased from the recorded image data even when the original 30 is written with the marker pen. Therefore, it is possible to output the image data excluding the unnecessary marker 33, and even if the original document is written with the marker pen, what is recorded as a file can be the same as the original document. Further, since the area in the marker 33 is recorded as the image document name, it can be used for searching the image data.

[Modification] An image filing apparatus of a modification will be described. The image filing device of the modification is
When the original document 30 shown in FIG. 8 is printed, every page is processed by one reading scan. When the original is placed on the original feeding device 101 and the start button is pressed,
The image filing apparatus conveys the document on the document table glass 102 in order from the fifth page, and scans the document.

At this time, reading scanning is performed in the red erasing mode. The read image data is binarized by the core unit 10, sent to the file unit 5, and recorded in the external storage device 6. In addition to the image data, if color is detected as a result of detection by the color detection circuit, the area information of the marker 33 is the core information.
It is sent to the file unit 5 via 0.

In the file section 5, the image data of the area surrounded by the marker 33 is cut out from the image data stored in the memory A 506 based on the area information and recorded in the external storage device 6 as the image document name.

Thus, with only one reading scan,
The same effect as that of the above-described embodiment can be obtained.

[0080]

According to the image filing apparatus of the first aspect of the present invention, when the document is read by the image reading means and converted into image data, and the converted image data is recorded by the image recording means, Since the marker detecting means detects the marker printed on the original and the erasing means deletes the detected marker from the image data, the image data can be output excluding unnecessary markers. Therefore, even if the original document is written with the marker pen, the one recorded as a file can be the same as the original document.

According to the image filing apparatus of the second aspect, since the area specified by the detected marker is recorded in addition to the image data by the area recording means, the area specified by the marker is regarded as an image document. By doing so, it can be used for searching image data.

According to the image filing device of the third aspect, since the color of the marker is detected by the color detecting means, the marker color can be selected and erased.

According to the image filing apparatus of the fourth aspect, in the image filing method of reading an original, converting it into image data, and recording the converted image data, a marker marked on the original is detected, Since the detected marker is deleted from the image data, the image data can be output by removing unnecessary markers. Therefore, even if the original document is written with the marker pen, the one recorded as a file can be the same as the original document.
