Abstract

PURPOSE:To prevent loss of effective data in a document by reading out data except data in certain addresses to a memory in accordance with a set size if the register size of a picture is larger than the set size set at the time of displaying picture information. CONSTITUTION:A CPU 1 takes out file management information, which is registered on an optical disk of a storage device 2, together with read picture information. It is discriminated whether the file register size for picture information registration is equal to the display size or not. If it is discriminated that the register size is larger than the display size, the CPU 1 initializes a memory 4 and executes the read-in processing to transfer data from the storage device 2 to the memory 4 thereafter. Information read from the storage device 2 is transferred to the area, whose X address is (m2-m1)/2-(m2+m1)/2 and Y address is (n2-n1)/2-(n2+n1) /2, of the memory 4, and approximately entire picture information except the peripheral part is displayed though the display size is smaller.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a filing device that searches for and outputs specified document information from a large amount of document information such as characters and drawings stored in a storage device.

[Background Art] In recent years, with the development of a highly information-oriented society, a large amount of information is being generated every day, and in order to effectively utilize this information, there is a need for more efficient and systematized information management. For example, it is expected to improve efficiency and systematize the operation and management of large amounts of patent-related documents and information, such as patent and utility model publications and public notices. In response to these expectations, the Japan Patent Information Organization (JAPIO) is planning to launch information services such as published patent publications.

Conventionally, as mentioned above, in order to meet the demands for efficiency and systemization of the management of large amounts of information, storage devices have been developed that read image information of documents consisting of characters, drawings, etc. by optical two-dimensional scanning. A filing device has been developed and put into practical use that searches the stored information for specified necessary image information at high speed, confirms it on a CRT display, etc., and outputs it as a hard copy. (For example, see JP-A-57-78251 and JP-A-57-78255).

By the way, in the above-mentioned filing device, a lot of image information is registered in the storage device, but in order to effectively utilize the storage capacity of the storage device, the size of the storage area is adjusted according to the size of the document to be registered. It can be specified. Therefore, data of various sizes coexist in the storage device.

On the other hand, when reading data from a storage device that contains data of various sizes as described above and displaying it on a CRT display or outputting it as a hard copy, the output image information is transferred from the storage device to the memory. (page buffer), and one designated unit of image information in this page buffer is supplied to a CRT display device or hard copy device. The display size of the output data is specified by the user.

[Problems to be Solved by the Invention] However, in the above filing device, if the size of the document registered in the storage device is different from the output size specified by the user at the time of output, for example, If image information with a registered size larger than the set size is transferred to the page buffer, data may have been previously stored outside the range corresponding to the above output size in this page buffer due to the need for image editing, etc. However, there was a problem that this data would be destroyed. Also, if the registered size is larger than the set size, when the registered image data stored in the storage device is read from the first address, the registered image data near the end address will not be read to the page buffer.
Generally, there has been a problem in that the registered image is displayed in a skewed state, even though a large amount of valid data exists in the center of the registered image of a document.

An object of the present invention is to display the display size even if the registered size registered in the storage device is larger than the display size specified by the user.
To provide a filing device that can read valid data in a document without losing it.

[Means for Solving the Problems] Therefore, the present invention scans a document consisting of characters, figures, etc. in a line in the X-axis direction, and sequentially shifts this scanning in the Y-axis direction perpendicular to the X-axis direction. The image information on the document is read by optical two-dimensional scanning, and the read image information is stored in a storage device along with the registered size of the document, and the image information of the document stored in the storage device is In a filing device that searches for specified image information, reads it into memory, and outputs it to an output device in a visible state, if the registered size of the image information is larger than the size set when displaying the image information. , among the X address and Y address of the storage area determined corresponding to the above two-dimensional scanning of the storage device in which the registered image data is stored, the beginning of each of the X address and Y address corresponds to the above setting size. The present invention is characterized in that it includes read control means for reading data into the memory while leaving data at fixed addresses from the address to each final address.

[Operation] The set size set by the user when outputting image information is compared with the registered size of image information output from the storage device. When the registered size is larger than the set size, the readout control means causes data in the center of the registered image stored in the storage device to be read out and transferred from the storage device to the memory.

[Example code] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A block diagram of a filing device according to the present invention is shown in FIG.

The above filing device is a central processing unit (hereinafter referred to as C
It is abbreviated as PU. It consists of a storage device 2, a buffer 3, a memory 4, a transfer circuit 5, an output device 6, etc. whose operations are controlled by the CPU 1.

The storage device 2 is a large-capacity storage device, such as an optical disk device, that stores image information of a document consisting of characters, graphics, etc. written on a sheet-like recording material such as vapor. For example, an original (document) on which characters, drawings, etc. are written or printed is scanned in a line in the X-axis direction on an optical disk (not shown) of this optical disk device, and this scanning is performed on the X-axis. The image information read by optical two-dimensional scanning that is sequentially shifted in the Y-axis direction perpendicular to the Y-axis direction is sequentially registered (file) together with the registered size of the recording material. In the output mode of the image information registered in the storage device 2, data corresponding to one line of the two-dimensional scan is sequentially output to the S+ sofa.

The operation of the buffer 3 is controlled by the transfer circuit 5, and in the image information output mode, it temporarily stores data corresponding to one line of image information output from the storage bag R2. Of the data corresponding to one line of temporarily stored image information, as will be described later,
Is the data included in the area necessary for display or the transfer circuit 5
The data is transferred to the memory 4 according to a command from the . The buffer 3 also temporarily stores data corresponding to one line of image information sent from the memory 4 in the image information registration mode, and transfers it to the storage device 2. Memory 4 above
has a storage capacity for at least one page of a document read by optical two-dimensional scanning.

The transfer circuit 5 controls data transfer between the storage device 2 and the memory 4 by the buffer 3. In the image information output mode, data transfer from the storage device 2 to the memory 4 by the buffer 3 is based on the file registration size of the original registered in the storage device 2 and the display size of the data stored in the memory 4. For example, depending on the relationship between
This is done as shown in FIGS. 3 and 4.

In Figures 2, 3, and 4, φ, 1.2, ·

As can be seen from the above figures 2, 3 and 4,
Data is transferred from the storage device 2 to the memory 4 using the X direction transfer start address XS, the Y direction transfer start address YS,
Direction data transfer amount XL and Y direction data transfer ff1Y
L, an X-direction data acceptance start address XD, and a Y-direction data acceptance start address YD.

The X-direction transfer start address XS is read by two-dimensional scanning with a laser beam, and among the data constituting each line of image information registered in the storage device 2, the data is first transferred from the storage device 2 to the buffer 3. X of the data sent to
It is an address. Further, the Y-direction transfer start address YS is read by two-dimensional scanning with a laser beam, and the first 1. : Storage device 2 to buffer 3
This is the number of lines counted before being sent out. Further, the X-direction data transfer amount XL is the amount of data sent from the storage bag R2 to the buffer 3 out of one line of image information data. Furthermore, the Y-direction data transfer 1iYL transfers data from the storage device 2 to the buffer 3 for display among the lines constituting the image information.
is the count of lines sent out.

On the other hand, the above X direction data acceptance start addresses XD and Y
The direction data reception start address YD is the X address and Y address of the memory 4, respectively, where data from the storage device 2 side is first received on the memory 4 side.

The above X-direction transfer start address XS, Y-direction transfer start address YS, X-direction data transfer amount XL, Y-direction data transfer amount YL, X-direction data acceptance start address XD, and Y-direction data acceptance start address YD are determined according to the program described later. , managed by the CPUI.

The output device 6 displays the image information stored in the memory 4 on a CRT display (not shown) or a hard copy device (not shown).

CPU that controls the filing device having the above configuration
Program 1 is the <main routine>.

<Resize processing routine>, <Continuous reprinting processing routine>
, <registration processing routine>, and print processing routine>.

Below, the <main routine>, <size change processing routine>, <continuation processing routine>, and <registration processing routine> particularly related to the present invention will be explained.

<Main routine> FIG. 5 shows the main routine of the CPUI.

When the CPUI is reset and the program is started, the CPUI first performs initial settings for initializing the memory 4 and initializing the display size (step Sl). Next, the CPUI displays the initialized memory 4
The contents of the initialized memory 4 are outputted to the output device 6.
The content of is displayed on a CRT display (not shown) at the initialized display size (step S2).

In this state, the user specifies the display size using the keyboard (not shown), and
A command for either registration processing or print processing is input (step S3).

When a command is input, the CPU determines the input command (step S4), and if the command is a command to change the size of the display size, it performs a size change process (step S4).
Execute subroutine S5).

Further, if the above command is a read command, read processing (subroutine S6) is performed, and if it is a registration processing command, image information registration processing (subroutine S7) is performed.
In the case of print commands, print processing (subroutine S8) is executed respectively. Then, after each of the above processes is completed,
The CP'UI returns to execution of the display process (step S2).

<Size change processing routine> FIG. 6 shows the size change processing routine S5.

In this size change processing routine S5, the currently set display size of image information is changed to the setting size set by the user in step S3 of FIG. 5 (step 5501 of FIG. 6).

<Continuation processing routine> FIG. 7 shows the successive output processing routine S6.

In this continuous processing routine S6, when the user selects a file from the keyboard (not shown) in order to read necessary image information from the image information (files) registered in the storage device 2 (step 5601), the CPU
I retrieves the file management information registered on the optical disc of the storage device 2 together with the image information to be read (step S602).

The CPU then determines whether the file registration size at the time of registration of the image information included in this file management information is equal to the display size set in step 5501 of FIG. 6 (step 7). Figure step 5603).

If it is determined in step 5603 that the file registration size and the display size are equal, the CPU 1 determines that XS=φ
, YS=φ, step 5604), XD−φ, YD
-φ (step S 605), XL=X direction front size, YL=Y direction display size (step S 606), and then read processing (subroutine 5) to be described later.
607) is executed.

Through the execution of this series of steps 5604, 5605, 5606 and subroutine 5607, all the data constituting the image information read from the storage device 2 is transferred to the memory 4, and the data that constitutes the image information read from the storage device 2 is transferred to the output device 6 with a size equal to the file registration size. The above image information is displayed (see Figure 2).

On the other hand, if it is determined in step 5603 that the file registration size and the display size are not equal, the CPUI displays a message on the display screen of the CRT display of the output device 6 that the display size is not equal to the file registration size. (Step 5608). This display allows the user to know that the display size is not equal to the file registration size.

Thereafter, the CPU determines whether or not to continue reading the image information data from the storage device 2 (step 56).
09), if this continuous output processing is not to be continued, the read processing routine S6 is ended.

On the other hand, if the CPUI determines to continue the read processing routine S6, it determines whether the displayed size is larger than the file registration size (step 5612).

If it is determined in step S6!2 that the display size is larger than the file registration size, the CPU 1 initializes the memory 4 (step 5613). This is because if you try to transfer data from the storage device 2 to the memory 4 and display the image information without initializing the memory 4, the display size will be larger than the file registration size, so the output device 6 will This is to prevent unnecessary data that has already been stored in the memory 4 from the data transfer center from being displayed around the currently displayed image information.

After initializing the memory 4, the CPU 1 sets XS=φ.

Let ys=φ (step 5614). Also, cpUl
XD=(X direction display size)/2-(Y direction display size)/2. YD=(Y-direction display size)/2-(Y-direction registered size)/2 (step 5615). Furthermore, CPU1 has XL, = (X direction registered size), YL
= (Y direction registration size) (step 9616).

After executing steps 5614, 5615, and 5616 above, the CPUI executes a read process (subroutine S607) for transferring data from the storage device 2 to the memory 4. This series of steps 5614, 5615, 561
6 and subroutine 5607, the image information read from the storage device 2 is as shown in FIG.
The X address of memory 4 is from (m, -mυ/2 to (ms+
n++)/2, Y address is transferred from (nt-nυ/2 to (nt + r++)/2 area. As a result, the above screen is displayed in the center of the display screen of the output device 6 (third (see figure).

On the other hand, if it is determined in step 5612 that the display size is smaller than the file registration size, the CPU
X5-(X-direction registration size)/2-(X-direction display size)/2. YS=(Y-direction registered size)/2-(Y-direction display size)/2 (step 5617). In addition, the CPUI is set to XD=φ, YD-φ (step 5
618). Furthermore, the CPUI sets XL=(X direction display size) and YL=(Y direction display size) (Step 5
619). Steps 5617, 5618 and 5 above
After executing 619, the CPUI transfers data from storage device 2 to memory 4.
Read processing (subroutine 5607) to transfer data to
). This series of steps 5617, 5618
．． By executing 5619 and subroutine 5607,
As shown in FIG. 4, from the storage device 2, the X address of the storage device 2 is (m, -m,)/2 to (t+ +
l1lt)/2, Y address is (n, -n-)
Data in the area from /2 to (r++ + nt)/2 is transferred. As a result, even if the display size is smaller than the file registration size, the display screen of the output device 6 is
Of the image information of the document read out from the storage device 2, the entire area is normally displayed, excluding the peripheral portion where there is no image information.

FIG. 8 shows the subroutine 5607 (reading processing routine) shown in FIG. 7 above.

In the read processing routine 5607, when transferring data from the storage device 2 to the memory 4 via the buffer 3, the CPU
Clear the processing line variable Y which is the address (step 56071) L,,NT Transfer one line of image information data from the storage device 2 to the buffer 3
(Step S6072). And C
The PUI updates the line being processed until YCNT≧YS, that is, until the line variable Y being processed reaches the Y direction rotation NT transmission start address YS (a loop that returns from steps 56073, 56076 and 56077 to step 56072). ).

By updating the line during the above processing, Y CN T≧YS
Then, the CPUI transfers the data stored in the buffer 3 to the memory 4 (step 56074). YL
=YI, -1, YD=YD+1, subtract 1 from the current Y-direction data transfer ff1YL, and add 1 to the Y-direction data reception start address YD (step S6075).

Then, the line being processed is updated as YCNTY +1.

NT Repeat steps 56072 to 86076, transfer data from buffer 3 to memory 4 lines at a time, and when Y-direction data transfer 1tYL becomes φ (step S 6077), CPUI registers to end read processing routine 5607. Processing Routine> FIG. 9 shows the registration processing routine.

In this registration processing routine, when it is determined that a command input manually from a keyboard (not shown) is a registered command (steps S3 and S4 in FIG. 5), the CPU
Step 5701) sets the X-direction transfer start address XS and Y-direction start address YS of the memory 4 to φ, respectively.
, sets the start address of data transferred from memory 4. Next, XL=display size X, YL=display size Y, and the write amount of data transferred from the memory 4 is set (step 5702).

As described above, when the start address of the data to be transferred from the memory 4 and the amount of data to be written are set, the CPUI transfers the data from the memory 4 to the storage device 2 using the buffer 3 and executes the write process. (subroutine S
703), the management information of the data is registered (step 5704), and the registration processing routine S7 is ended.

The above write processing routine 5703 is shown in FIG. 1θ.

In the write processing routine 5703, cPUl transfers the data stored in the memory 4 to the buffer 3 line by line starting from the data at the first address in step 57.
031), writes the data amount of XL from the buffer 3 to the storage device 2 (step S7032). And YS=YS+l.

As YL=YL-1, transfer address Y from memory 4
S is updated and the Y-direction transfer amount YL is subtracted (step S
7033).

The above steps 57031 to 57033 are repeatedly executed, and when the Y-direction transfer ff1YL becomes φ in step 57034, the CPU ends the write processing routine 5703.

[Effects of the Invention] As is clear from the above detailed description, according to the present invention, when registering files are successively generated, if the registered size of document image information is larger than the set size, the image information is stored in the storage device. Of the registered images that are registered, the data in the center, where there is generally a lot of aesthetic data, is read out and transferred from the storage device to the memory, so even if the set size is smaller than the registered size, it will still be valid in the document. can be displayed without losing any data.
