Abstract

PURPOSE:To easily and effectively carry out the prescribed document registering/retrieving operations by changing the text information including a retrieving code into a pattern, printing this pattern together with display of characters for production of a text sheet, and putting this text sheet on a document to set them on an automatic sending device. CONSTITUTION:A text sheet S is put on a document and set on an automatic document feeder (ADF). Then the sheet S is inputted to a picture input device. Thus the picture images of one or plural parts of a document are registered to an optical disk together with the text information. At the same time, a necessary document can be retrieved out of those many registered documents. A pattern of the text information is read after the 1st special patterns 13A and 13B and the 2nd special patterns 14A and 14B of the sheet S are correctly read. The five dots scattered at a center part and bearing the X marks are read and the black or white area is decided inside a frame when >=3 of five dots are black or white respectively. So that the reading accuracy is improved within a frame of 8 bits (b7 - b0) of each digit of information columns 1 - 12. This procedure is applied to eight frames and therefore the black/white patterns of each digit can be correctly read.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to 1, for example, industrial property documents, etc.
A registration search method for an optical filing system in which a large number of documents of various types are registered on an optical disk along with a search code corresponding to each document via an image input device, and the registered documents are arbitrarily searched using the search code. It is related to.

[Prior Art] In this type of optical filing system that has been known in the past, in both cases of registering a single document and searching for registered documents, a search code corresponding to each document to be registered must be manually entered on a keyboard. It was something to do.

To be more specific, when registering one document, the following steps are performed: setting the input mode of the image input device, ■ inputting the image of the document onto the optical disk using the image input device, ■ inputting the search code corresponding to the above document on the keyboard. Furthermore, when searching for registered documents, the user had to enter a search code corresponding to the document that needed to be retrieved using the keyboard.

[Problems to be Solved by the Invention] In the conventional optical filing system registration search method described above, when there are many documents to be registered, an automatic feeder (hereinafter referred to as ADF) is attached to one image input device. Also, because the work in ■ and ■ requires a lot of effort and time, the efficiency of the entire registration process is low.Furthermore, when searching, many search codes have to be entered manually, which just makes the search process inefficient. In addition, there was a possibility that a specified search could not be performed because the user forgot the search code. Furthermore, there is an inconvenience that, both at the time of registration and at the time of search, only a person who is aware of the search code is able to execute the specified document registration and search.

This invention was made to solve the above-mentioned problems, and allows for easy document registration and search operations without the need for inputting search codes on a keyboard.
The purpose of the present invention is to provide a registration search method for an optical filing system that can be carried out efficiently and that allows a person to perform predetermined registration and search even if he or she has forgotten the search code or is unaware of the search code. do.

C Means for Solving the Problem] In order to achieve the above object, the registration search method for the optical filing system according to the present invention searches text information including a search code corresponding to a document to be registered in a black and white pattern according to a certain rule. Create a text sheet by converting to
By inputting the image into the image input device via the DF, the image of one or more copies of the document is registered on the optical disc together with the text information, and by inputting the text sheet into the image input device, the text information can be registered. It is characterized by searching for registered documents corresponding to.

Further, in the registration search method for an optical filing system according to the invention described in claim 2, black and white patterns that are identical to each other and have a size larger than the feeding position variation range of the ADF are formed at diagonally symmetrical positions of the text sheet. In addition to being printed, a black and white pattern with the same size as the text information pattern for detecting misreading is placed at one end of the text sheet in the direction orthogonal to the direction in which it is fed by the ADF, and near both the front and back ends of the text sheet in the feeding direction. pattern is printed.

[Operation] According to the present invention, a text sheet created by converting text information including at least a search code into a black and white pattern according to a certain rule and printing it together with character display is superimposed on a document corresponding to the search code. By inputting the information into the image input device via the ADF, the image of one or more copies of the document can be automatically registered on the optical disc together with the text information without requiring manual input to the keyboard. Further, when searching for a registered document, by inputting the text sheet into the image input device, the corresponding registered document can be easily searched without requiring manual input of a search code into the keyboard. especially,
During this search, the character display printed on the text sheet will serve as a reference for remembering the content of the specified registered document and the search code, so even if you have forgotten the search code, or if you are not aware of the search code, However, predetermined searches can be performed easily and accurately.

Further, according to the invention described in claim 2, by reading the same black and white patterns printed at target positions on the diagonal line of the text sheet, the document can be set in the ADF upside down. If the case or text sheet is A
To discriminate a text sheet from an image of a document to be registered even when the text sheet is fed at an angle within a range of variation in the feeding position of a DF. Furthermore, by reading a black and white pattern printed in the same size as the text information pattern near both front and rear ends of the ADF feeding direction at one end of the text sheet, the next text information and document to be read will be upside down. It is possible to eliminate errors in reading text information by detecting that the image input device is not working properly, that the image is tilted to a certain position, that the image of the black and white pattern is inappropriate, that the image input device is malfunctioning, etc.

〔Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a surface view showing an example of a text sheet S used in the registration search method of the optical filing system according to the present invention. In the figure, 1-12 indicates the reading mode of the image input device, material type, major classification code, medium classification code, minor classification code, company code, trading company code 5 person in charge code, order number, facility number 0, order amount, etc. This is a text information field in which a plurality of types of search codes, each corresponding to a document to be registered, are converted into a black and white pattern according to a certain rule and printed, as will be described later.

Each of these text information columns 1 to 12 is iof? As shown in Figure 2, it consists of 10 numbers from O to 9, 26 uppercase letters from A to Z, and 26 uppercase letters from a to Z.
46 lowercase English letters, 46 uppercase katakana letters from A to A including wo, A, and I.

It is expressed by the 12 lowercase katakana characters: tsu, 工, o, n, ya, yu, yo, wa, power, ke, two dakuten (゛), two handakuten (0), or a combination thereof.

As shown in Figure 2, each digit in each text information field 1 to 12 consists of 8 bits (b7 to bo), and each digit can be read by reading the black and white pattern of the top two bits (b7, be). It is standardized to determine the type and determine the content of each digit by reading the black and white pattern of the lower 6 bits (b5 to bo). Taking the digit pattern as an example, in 2 to 4 digits, the upper 2 bits (b7, b6) are both white, that is, 0, O, so it is determined that it is a number, and the remaining lower 6 bits) Any of the numbers O to 9 is determined by the combination of white and black (b5 to bo), that is, O and 1.

Also, for 5 digits, the upper 2 bits (b7.b6) are 0. Since it is l, it is determined that it is an English capital letter, and one of the English capital letters AZ is determined by the combination of O and 1 of the remaining lower pitches (b5 to bo). Below, 10
By determining the type and content down to the digit, the search code for order number is 322-B58196.
It can be read that

As described above, along with text information including search codes and reading modes converted into black and white patterns based on certain rules, characters representing specific content such as type, large, medium, small classification, company code, etc. Text information that needs to be displayed is printed on the shelf.

In Fig. 1, 13A and 13B are printed at symmetrical positions on the diagonal of the text sheet S, specifically, at the upper left and lower right of the drawing, respectively, in order to distinguish them from the image of the document to be registered. This is the first special pattern consisting of black, white, and incandescent. This first special pattern 13A, 13
B has a size larger than the feed position variation range of the ADF attached to the image input device (not shown), and A11lt
Even if there is an inclination within the above variation range during feeding by F, it can be determined as a text sheet. In addition, the first special patterns 13A and 13B were printed at symmetrical positions with respect to the diagonal line -L of the text sheet S.
This is to make it possible to accurately determine that the text sheet S is set upside down in the ADF.

In this way, by printing the first special patterns 13A and 13B, even if the text sheet S is turned upside down or the feeding posture by the ADF is tilted, the text sheet S can be reliably identified and the text sheet will remain as a document. It is possible to prevent a text sheet from being erroneously registered as a document, and from erroneously registering a document following a text sheet as a document based on the text information of the previous text sheet.

At t-3 in the vJ1 diagram, 14A, 14BJt At one end of the text sheet S in the direction y orthogonal to the feeding direction X by the ADF, and near both front and rear ends of the feeding direction X, specific , a second special pattern for detecting misreading is printed in black, white, black and white at the upper right and lower right of the drawing, respectively. This second special pattern 1
4A and 14B have the same size as the black and white patterns in the text sheet information columns 1 to 12, and if these second special patterns L4A and 14B cannot be read normally, the text sheet S will be upside down. It is possible to detect errors in the subsequent reading of text information due to reasons such as the image being tilted, the darkness of the black and white pattern being inappropriate, or the image input device malfunctioning.

By the text sheet S discrimination function and misreading detection function using the first special patterns 13A, 13B and the second special patterns 14A, 14B, it is possible to accurately register and search text information and documents. .

The text sheet S as described above can be easily created using a general-purpose personal computer and printer. By superimposing this text sheet S on a document and inputting it into an image input device via ADF, an image of a part or multiple copies of the document is registered on an optical disk (not shown) together with the text information, and the text sheet S
By inputting the desired document into the image input device in the same manner as at the time of registration, it is possible to search for a desired document from a large number of registered documents.

Here, the first special patterns 13A, 13B and the second special pattern 14A in the text sheet S,
14B can be read correctly, the next step is to read the pattern of text information. The method of reading the pattern of this text information will be briefly explained below.

(8 bits for each digit in text sheet information columns 1 to 12)
In order to improve the reading accuracy within the frame of (b7 to bo),
For example, as shown in Figure 3, among the 81 dots in the frame,
The five dots with X marks scattered in the center are read, and depending on whether three or more of them are black or white, it is determined whether the frame is black or white. By doing this for each of the eight frames, the black and white pattern in each digit can be read correctly. In this case, the recognition rate can be increased by increasing the size of each pattern, that is, the reading unit frame, or by increasing the number of read dots, but in this case, the amount of information on one text sheet S decreases. The size of the frame and the number of dots to be read must be appropriately determined by considering the nature of the document to be registered.

FIG. 4 is a surface view showing another example of the text sheet S used in the registration search method of the optical filing system according to the present invention.
The first special patterns 13A, 13B are divided into four rectangular parts and are arranged at symmetrical positions on the diagonal lines of the upper right and lower left in the drawing, and the second special patterns 14A, 14B are arranged in the opposite direction from the above embodiment. Placement at the upper left and lower left on the drawing of text sheet S, and each text sheet information column l~1
20 digits as a pattern representing the text information of 1.
It uses a JIS code with 4-bit digits.

Note that it is also possible to use a shift JIS code 4-code as a pattern representing text information.

[Effects of the Invention] As described above, according to the present invention, documents can be edited by simply placing a text sheet over the relevant document and setting it in the ADF, without requiring manual input on the keyboard. Along with images, text information including search codes can be automatically and efficiently registered on optical discs, and by simply setting the above text sheet in the ADF, there is no need to manually enter information such as search codes into a keyboard. A desired document can be easily and quickly searched for and retrieved without any trouble. Moreover, if you prepare a text sheet, even people who do not know the search code can perform the specified registration and search.
There is no need to recognize each search code, and it is very effective in filing many documents so that many people can search them.

Furthermore, the text sheet of this invention can be created using a commonly used personal computer and printer, so no special paper is required; It can also save labor.

Furthermore, the input method of the present invention allows the input work to be performed in advance and in one distributed work. In other words, the input work can be divided among the work of creating a text sheet, the work of classifying and organizing documents for input, and the work of automatically registering them on the ADF, making efficient use of the optical filing system. can. Further, by using the text sheet of the invention described in claim 2, it is possible to prevent the document from being registered in a tilted manner or in an upside-down manner.
