JP 2002-245075 A

In the prior art, the scanned image of the paper document to be discarded is stored in the storage device, so that even after the paper document is discarded, the document can be browsed with the filing device, or the paper document is made unreadable. It can be discarded. However, there are the following problems when storing scanned images of paper documents for disposal.
(1) Since the original electronic document and the image data of the paper document storing the image data are also accumulated, an unnecessarily large storage capacity such as a hard disk capacity is required, and the search range of the stored document is widened.

Conventionally, when a scanned image of a paper document to be discarded is stored, it cannot be identified that the electronic document that is the original paper document or a scanned image is stored in the storage function. Therefore, since all the images of the document to be discarded are accumulated, there is a possibility that the image of the document having the original electronic document or the scanned image of the same document is accumulated a plurality of times. Therefore, a large capacity of a hard disk or the like for storing images is required. Further, when displaying accumulated images, there may be a plurality of similar images, the search range may be widened, and the search time may be long.
(2) It is not easy to identify whether there is information such as annotation other than the original information in the paper document.

  Even if an electronic document that is the original of a paper document to be discarded or scanned image data has already been accumulated, an important annotation may be attached to the paper document. Whether or not there is an annotation requires a function of recognizing characters from the scanned image data of the paper document and confirming the identity with the electronic document that has already been stored or the characters of the scanned image data of the paper document. .

  Accordingly, an object of the present invention is to preliminarily determine whether an electronic document as an original document or image data obtained by scanning the paper document already exists in the storage device when image data of the paper document is accumulated and the paper document is discarded. By confirming, there is no need to provide a plurality of similar images, the search range is not increased more than necessary, and a method and apparatus for shortening the search time are provided. Another object of the present invention is to store the image data if the paper document is annotated even if the storage device already has the original electronic document or the scanned image data of the paper document. Thus, it is an object of the present invention to provide a method and an apparatus for referring to a document with an annotation later.

(1) Means for avoiding accumulating image data again when there is an electronic document as an original of a paper document or image data obtained by scanning the paper document;
Means for reading the feature value of the content of the paper document, means for reading the feature value of the content of the electronic document stored in the storage means, means for comparing the feature value of the paper document and the feature value of the electronic document, A document management apparatus comprising means for registering and storing scanning information of the paper document according to the comparison result, and means for discarding the paper document. It is possible to avoid re-accumulating the image data of the paper document in which the scanned image data exists.

That is, the electronic document that is the original of the paper document to be discarded or the function of determining whether the image data obtained by scanning the paper document is already in the storage device does not accumulate redundant electronic data. This eliminates the need to use a storage capacity such as a hard disk capacity, and the search range does not become unnecessarily wide, so that the search time is shortened and the search can be performed in a short time.
(2) means for identifying whether there is information such as annotation in addition to the original information in the paper document;
Means for reading the feature value of the content of the paper document, means for reading the feature value of the content of the electronic document stored in the storage means, means for comparing the feature value of the paper document and the feature value of the electronic document, According to the document management apparatus, comprising: means for simultaneously displaying the image data of the paper document and the data of the electronic document according to the comparison result; and means for storing or discarding the image data of the paper document It becomes possible to identify that there is information such as annotation in addition to the original information in the paper document.

  That is, when an important annotation or the like is added to a paper document, the image of the paper document is stored even if the electronic document that is the original of the paper document or the image data of the paper document is already stored in the storage device. Data can be registered, and annotated documents can be referenced later.

  The effect of the present invention is that, when image data of a paper document is accumulated and the paper document is discarded, it is confirmed in advance whether the original electronic document or the image data obtained by scanning the paper document exists in the storage device. As a result, a plurality of similar images are not present, the search range is not increased more than necessary, and the search time can be shortened. Another effect of the present invention is that, even when the original electronic document or the image data obtained by scanning the paper document is stored in the storage device, the image data is stored if the paper document is annotated. Thus, it is possible to refer to a document with an important annotation later.

  In the first embodiment, means for reading feature values such as the contents of a paper document to be discarded, means for reading feature values such as the contents of a stored electronic document, the feature values of the paper document and the electronic document Means for comparing whether characteristic values are the same, means for registering and storing scanning information of the paper document if there is no electronic document having the characteristic value of the paper document, and after registering the scanning information, A document management apparatus including a means for discarding a paper document will be described.
