Generally, an electronic filing device that stores image information in a recording medium is configured to add a keyword corresponding to the image information when storing the image information and to search the stored image information by the keyword. ing.

Recently, there has been proposed a device that performs this keyword input using a mark sheet, that is, a device that scans a mark sheet on which a keyword is marked and a document and adds the keyword marked on the mark sheet to the image information of the read document.

This device does not require a keyboard as in the past, and is convenient for people who are not familiar with keyboards.

However, if there is only one size of mark sheet and the size of the mark sheet and the size of the original are different, it is not possible to feed the mark sheet and the original to the reading section at once by the original feeding device, and read the mark sheet and the original. Since it has to be read separately, it is troublesome.

Even if a mark sheet of the same size as the original is prepared, the mark area of another size mark sheet at the same position as the mark area of another mark sheet has a different meaning. There is a risk that

There are various sizes of read sheets to be recorded and stored, but when there is only a certain size of mark sheet paper, that is, when a mark sheet paper of a different size from the read sheet is used, the mark sheet paper and the read sheet are stacked. If you use mark sheet paper of the same size as the reading paper to prevent feeding defects when feeding sheets sequentially from the copy unit to the reading unit, the mark position of the mark sheet paper May be different, and there is a problem that the keyword is erroneously recognized.

[Object of the Invention] In order to continuously read a mark sheet and originals of various sizes at one time, the present invention reads a mark sheet of the same size as the original together with the original and accurately decodes marks on different mark sheets depending on the size. An object of the present invention is to provide an image storage / retrieval device that can use keyword information of continuously read originals.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

FIG. 1 is a block diagram showing the basic structure of an electronic filing device embodying the present invention.

In the figure, 1 is an image reading unit for reading the image information of the mark sheet paper 2 and the reading paper 3, and the read image information plays a role.
It is stored in RAM4. Reference numeral 5 determines whether the sheet of the image read by the image reading unit 1 is the mark sheet 2 or the reading sheet 3, and the length of the sheet conveyed to the image reading unit 1 in the conveying direction is determined. , A control unit that detects based on the paper detection signal h from the paper presence / absence detection unit 6 that detects the passage / non-passage of the paper, and controls the input of the image signal read by the image reading unit 1 to the RAM 4. , And controls the input to the recording unit 7 which stores the signal of the RAM 4 for image reproduction. In addition, the control unit 5 defines the reading area when the sheet conveyed to the image reading unit 1 is the mark sheet 2 based on the detected size of the sheet, and the skewed sheet provided on the mark sheet 2 as described later. From the check mark, it is determined whether the mark sheet paper is correctly positioned at the predetermined position of the image reading unit 1,
This point will be described in detail later in the description of the mark sheet paper.

Then, when the mark sheet paper 2 is correctly conveyed to the predetermined position of the image reading unit 1 without skewing, the control unit 5 decodes the mark position such as a keyword provided on the mark sheet paper 2, A mark such as a keyword is converted into code information from the mark position and stored in the RAM 4 in charge. Then, when the code information for one case is stored in the RAM 4, the code information for the mark sheet paper is recorded in the recording unit 7. Next, when the image read by the image reading unit 1 is a reading sheet, the image information is stored in the RAM 4 and is recorded page by page in the recording unit 7 to be recorded in the previously recorded code information. Be combined.

The image information of the reading paper recorded in the recording unit 7 in this way is searched as needed by inputting a keyword provided on the mark sheet paper 2 with a keyboard or the like, and the image is displayed on the printer, CRT, or the like. Is played.

Next, an example of an electronic filing device embodying the embodiment shown in FIG. 1 will be described with reference to FIG.

In the figure, 10 is an image reading unit, which is provided below a glass plate 11 on which a conveyed sheet is placed and which illuminates a sheet on the glass sheet 11 and an illumination optical system 12 CCD that reads the image by receiving the reflected light from the paper illuminated by the
It is configured by a light receiving unit 13 including a line sensor and the like. The illumination optical system 12 is composed of a lamp (not shown), a mirror (not shown), and the like. The mirror is moved in the direction of arrow A to expose and scan the sheet. Reference numeral 14 denotes a sheet feeding section, which is used to stack the mark sheet 2 and the reading sheet 3 with the image side thereof facing downward.
The sheet of the lowermost layer is sent out to the sheet feeding roller 15 at the same timing by a registration roller (not shown). In the drawing, an example in which one sheet of reading paper 3 is stacked on three pages and one sheet of reading paper 3 is stacked in succession are shown. Then, the paper sent out by the paper feed roller 15 moves on the conveyance path 16 and moves to the glass plate 11 of the image reading unit 10.
The sheet is conveyed to the front edge 11a (hereinafter referred to as the reading start position) and stopped, and after the image reading process is completed, the sheet is discharged onto a sheet discharge tray (not shown) by the sheet discharge roller 17. Reference numeral 18 denotes an optical switch provided on the conveyance path 16 between the image reading unit 10 and the paper feeding unit 14,
From the light emitting element 18a located above the transport path 16 to the transport path 1
When the sheet conveyed is blocked from the light emitted toward the light receiving element 18b located below 6, the paper detecting signal h is output from the light receiving element 18b to the controller 1.

By the way, the sheets stacked in the sheet feeding unit 14 are not necessarily all of the same size, and sheets of different sizes may be stacked. Naturally, different sizes of mark sheet sheets are also stacked. That is, the mark sheet paper 2 having a size that matches the size of the reading paper 3 is stacked on the paper feeding unit 14 together with the reading paper 3. However, the mark sheet paper 2 is standardized as shown in FIG. 3, and the mark position is determined for each size.

The mark sheet paper 2 is provided with skew check marks 2a, 2a on both sides of the front end in the transport direction, and a line is placed under the check marks 2a, 2a to indicate that the sheets are mark sheet paper in order. 2b, a timing mark 2c for instructing to read and store the following marks, a keyword mark 2d indicating a keyword, and a page number mark 2e indicating the number of read sheets are provided and are displayed below the keyword mark 2d. The keyword mark corresponding to the existing keyword item column 2f is filled in with a pencil or the like to encode the keyword. Similarly to the keyword mark 2d, the page number mark 2e is designed such that the mark corresponding to the page number display field 2g displayed at the bottom is painted black to encode, for example, the page number of the reading paper 3. When is 3 pages, the page number mark 2e corresponding to "3" is blackened.

These mark positions are previously stored in the control unit 5 for each size of the mark sheet, and the control unit 5 performs the following processing depending on the marks read by the image reading unit 10.

If the sheet conveyed to the image reading unit 10 is, for example, the mark sheet 2, the skew check marks 2a, 2a
Is read, the preset reference skew check mark position of the mark sheet paper corresponding to the size of the mark sheet paper 2 is compared with the actually read skew check mark 2a, 2a position, and the deviation is detected. If it is within a range that does not hinder the subsequent reading of the mark, it is determined that the mounting state is good, and the reading of the next mark is performed.
If the deviation exceeds the range, the placement state is determined to be no, the subsequent mark reading is stopped, and a warning lamp or the like is turned on to notify the operator that the mark sheet 2 cannot be read.

When it is determined that the placed state of the mark sheet paper 2 is good, the mark sheet pattern 2b is read next. When the pattern 2b is detected, it is determined that the sheet being read is the mark sheet paper, and the next timing mark 2c is read. An instruction is given to store the image after reading in the RAM 4 as a keyword. At the time of reading the keyword mark 2d, the illumination optical system 12 is controlled so as to expose and scan only the display range of the keyword mark 2d corresponding to the size detected by the paper detection signal h from the optical switch 18. That is, after reading the timing mark 2c, the lamp of the illumination optical system 3 is turned off until the display range of the keyword mark 2d is reached.

When the reading of the keyword mark 2d is completed, the keyword information is recorded in the recording unit 7 from the RAM 4.

Next, the read paper 3 is sequentially conveyed to the image reading unit 10 by the designated number of pages read by the page number mark 2e, and the image reading and the recording operation in the recording unit 7 are performed.

[Effects of Examples of Invention]

As described above, according to the present embodiment, the keyword mark is read by exposing and scanning the display range of the keyword mark according to the size of the mark sheet paper 2 detected by the optical switch 18. It is possible to prevent erroneous reading due to dirt and the like, and to reliably register the keyword.

Although the presence / absence of the sheet is detected by the optical switch in this embodiment, the presence / absence of the sheet on the sheet conveying path may be detected by a mechanical means such as a limit switch.
