Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document retrieval device,
In particular, the present invention relates to a document search device capable of generating an image based on code data of a document and performing a search using this image.

[0002]

2. Description of the Related Art Conventionally, the storage and management of a document created by a document creating device is performed by a document name (title) consisting of a character string in each document when the size is small such as a word processor or when the amount of data is relatively small. ) Was added individually. And re-edit this saved document,
When searching for reference or printing as a material, temporarily display a list of document names on a CRT or the like, select the one that seems to be the corresponding document, and then, enter the description. This was done by displaying the content on a CRT and confirming it.

However, in this case, an appropriate document name must be given to each document when saving the document, and it tends to occur in a department or company that creates many documents. In some cases, a document name similar to that of the document will be given.In such a case, even if a search is performed from the document name to narrow down the target, a large number of documents will eventually be displayed on the edit screen. Otherwise, the desired document cannot be searched.

For this reason, when the amount of documents to be searched is large, an electronic filing device has been proposed in which electronically recorded documents are displayed on a CRT just like flipping a paper document and searched. It is considered that the existing technology (for example, see Japanese Patent Laid-Open No. 61-193265) is applied.

[0005]

However, in this method, it is possible to uniquely determine a method of generating a page surface to be displayed as visual information, that is, image data on the display unit from code data to be searched. Can not.
For this reason, it is not possible to determine what kind of image data should be displayed before page turning.

That is, in the conventional document creating apparatus, even a relatively simple one such as a popular word processor, a "column" for dividing a vertically written page into upper and lower two columns or the like at the time of printing, Image with rich visual features such as "Footnote", where supplementary explanation items are written in small letters in different letters in academic documents, etc. It is possible to instruct it to be data. On the other hand, when a document is edited for new creation or change, what is displayed on the CRT for editing is image data such as a character string written on a manuscript sheet, which has so few visual features. Therefore, the image data actually printed and the CRT for editing
In many cases, there is a large difference, rather than not necessarily matching the image data displayed in. Furthermore, in a document creating apparatus realized by using document processing software such as troff or Tex on a general-purpose computer, this difference becomes even larger.

Further, there is a large difference between the image data actually printed as an article in a newspaper company, a publishing company, etc. and the image data displayed on the editing screen when the user prepares an original. Specifically, at the stage of creating as a manuscript, it is displayed as image data like a manuscript paper as with a normal word processor, but of course it is printed with a frame or a large heading,
The shape of the document described for convenience of other articles is different,
It is not uncommon for even colors to be added. Therefore, it is confusing for the user if it is not clear which of them is displayed and the page turning search is performed. For example, in a newspaper company, when a veteran newspaper reporter tries to refer to a past article when writing a new article, if the past article is written by himself, the characters are written on the manuscript paper, so to speak. The image data for editing as described above may be impressive, and the image data printed on a newspaper may be impressive when referring to an article written by another person.

As described above, there are advantages and disadvantages in whether the image data to be displayed when retrieving a document is the image data for editing or the image data for printing. It is not always possible to perform a good document search in. For this reason, it is desired to realize a document retrieval device that can easily retrieve a stored document regardless of its print history.

Therefore, illustration and description thereof will be omitted. In addition, the content of the document creation device incorporating the computer and the document processing technique by the document creation device, which is the premise of the present invention,
For example, Troff, Tex, Scribing, and various document processing by them are, for example, well-known techniques described in "Information Processing Handbook", Vol. Omit it.

The document editing unit 10 also serves as an input unit such as a keyboard for inputting a document as code data, a unit for generating image data from the input document such as a character generator, and a document search device according to the present invention. The display unit such as a CRT or a liquid crystal display is provided, and by using these, not only the user can interactively create and edit a document but also input it, and also search for the input document. In addition, it is possible to interactively set print control information such as whether to write a created document in vertical writing or horizontal writing, or whether to perform column setting or bag binding. Therefore, it goes without saying that the code data of the edited document also includes the print control information set in this way. Now, the edited code data is saved as a new document or overwritten on an existing document as an updated document and saved. When saving as a new document, the code data of the edited document is output to the signal line 500, and the signal line 501 outputs a value null indicating that the document identifier does not exist. On the other hand, when the code data of the edited document is overwritten and saved in the existing document, the code data of the edited document is written on the signal line 50.

When the value read via 1 is null, the code data read via the signal line 500 is stored with a new identifier. On the other hand, when the value read via the signal line 501 is not null, the read value is used as the document identifier, and the code data read via the signal line 500 is stored as the document represented by the identifier.

The generated image designating section 12 is a changeover switch in terms of hardware and outputs a "true value" to the signal line 505 when the changeover switch is "ON" and a signal line 505 when it is "OFF". "False value" is output to. Document search unit 13
Reads the code data of the document to be searched from the code data storage unit 11 via the signal line 503, generates image data based on the code data, and displays the generated image data on the display unit. Enables the document search.

The operation of the document retrieval unit 13 will be described in detail below. FIG. 2 is a configuration diagram of the document search unit 13. In the figure, 20 is a code data reading unit,
Reference numeral 21 is an image data generation unit, 22 is a display unit which is also used as a document editing unit, 23 is a document specifying unit, and these units are connected by signal lines 510 to 514.

Further, FIG. 3 shows the document specifying unit 2 shown in FIG.
It is a block diagram of 3. In the figure, 30 to 35 are buttons, 36 is a read control unit, 37 is a document identifier specifying unit, and these units are connected by signal lines 530 to 535. Further, FIG. 4 is a configuration diagram of the code data reading unit 20 shown in FIG. In the figure, 40 is a reading unit, 41 is an identifier storage unit, and both units are connected by a signal line 540.

Further, FIG. 5 is a block diagram of the image data generator 21 in FIG. In the figure, reference numeral 50 is an editing image generation unit, 51 is a printing image generation unit, 52 is a selection unit, and each of these units is a signal line 55.
It is connected by 0-551. The document search unit 13
The user of the document creating apparatus operates by pressing any of the buttons 30 to 34 in the document specifying unit 23.

Each of the buttons 30 to 34 is used to display the documents stored in the code data storage unit 11 after being converted into code data in the order of creation date and time or vice versa in a page-turning manner and the display thereof. If there is a search target document in the displayed documents, it is used for designating it. Only when the document is pressed, a button pressing signal is output to the corresponding signal lines 530 to 534, and the button is pressed. If not, nothing is output.

The read control unit 36 uses the signal lines 530 to 534.
Is detected to output a control command corresponding to the pressed button to the signal line 510. That is, when the button press signal is supplied via the signal line 530, the forward document read command is issued to the signal line 510 until the button press signal is supplied via any of the signal lines 531 to 534 thereafter. It is output periodically at intervals of 0.2 seconds. And this output is the other signal lines 531-5.
Stop when another button press signal is supplied via 34. When the button pressing signal is supplied through the signal line 531, the forward document reading command is issued only once in the signal line 5.
Output to 10. When the button pressing signal is supplied through the signal line 532, the backward document reading command is output to the signal line 510 only once. When the button pressing signal is supplied through the signal line 533, the signal lines 530 to 530 are then transmitted.
Until the button press signal is supplied to either 532 or the signal line 534, backward document read commands are periodically output to the signal line 510 at intervals of 0.2 seconds. Then, this periodic output is stopped when another button pressing signal is supplied through any of the other signal lines 530 to 532 and 534. When the button pressing signal is supplied through the signal line 534, the forward document read command or the backward document read command is periodically sent at 0.2 second intervals.
If so, the output is stopped thereafter, and if neither the forward document read command nor the backward document read command is periodically output, the non-output state is continued.

The identifier storage unit 41 in the code data reading unit 20 stores the identifier of the document last read by the reading unit 40. The initial value is null. When the reading unit 40 is supplied with the forward document read command via the signal line 510, the reading unit 40 reads via the signal line 540 the value stored in the identifier storage unit 41. When the read value is null, the reading unit 40 reads the earliest stored code data group of the document stored in the code data storage unit 11 via the signal line 503 and outputs the read data to the signal line 511. The document is output, and at the same time, the identifier of the document is read out via the signal line 504 and output to the signal line 512.
On the other hand, when the value read through the signal line 540 is not null, the read value is used as the document identifier and read through the signal line 540 in the code data group of the document stored in the code data storage unit 11. The document stored next to the document indicated by the identifier is read out through the signal line 503 and output to the signal line 511, and the identifier of the document is also read out through the signal line 504 and output to the signal line 512. Furthermore, when the reading unit 40 is supplied with the backward document reading command via the signal line 510, the reading unit 40 reads the identifier storage unit 4.
The value stored in 1 is read via the signal line 540.
When the read value is null, the reading unit 40 outputs the last stored one of the code data groups of the document stored in the code data storage unit 11 to the signal line 503.
The document identifier is read out through the signal line 511 and output to the signal line 511, and the document identifier is read out through the signal line 504 and output to the signal line 512. On the other hand, when the value read through the signal line 540 is not null, the read value is used as the document identifier and read through the signal line 540 in the code data group of the document stored in the code data storage unit 11. The document stored immediately before the document indicated by the identifier is read out through the signal line 503 and output to the signal line 511, and the identifier of the document is also read out through the signal line 504 and output to the signal line 512. .

The identifier storage section 41 reads the identifier of the document supplied via the signal line 512. Then, the stored value is updated to the value of the read identifier. Therefore, when the forward document read command is continuously supplied via the signal line 510, the code data read unit 20 stores the time when the code data of the document stored in the code data storage unit 11 is stored. When the backward document read command is continuously supplied, the code data storage unit 11 is read.
The code data of the document stored in will be read out in order from the most recently stored one.

The editing image generating unit 50 in the image data generating unit 21 reads the code data of the document supplied via the signal line 511, and the document creator represents the document represented by the code data by the contents of the document. Is generated as the same image data as when it is displayed on the display unit when it is changed, and then the generated image data is output to the signal line 550 for high speed display for retrieval.

On the other hand, the printing image generating section 51 reads the code data of the document supplied through the signal line 511 and uses the printing section 14 for printing when printing the document represented by the code data on the paper. Is generated as the same image data as the above, and the image data generated above is output to the signal line 551 for high-speed display for retrieval. At this time, at the time of generating the printing image data, it is determined whether or not to perform the column setting or the bag binding, by using the printing control information included in the code data.

The selection unit 52 reads the value supplied via the signal line 505. If the read value is a “false value”, the image data supplied via the signal line 550 is read and the image data is output to the signal line 513. The image data supplied via the signal line 551 is ignored. On the other hand, when the value read via the signal line 505 is the “true value”, the image data supplied via the signal line 551 is read and the image data is output to the signal line 513. The image data supplied via the signal line 550 is ignored.

The display unit 22 displays only one piece of image data lastly supplied via the signal line 513. When the user of the document creating apparatus presses the button 35 in the document specifying unit 23 while the desired document is displayed on the display unit 22, the button 35 outputs a button pressing signal to the signal line 535.

The document identifier specifying unit 37 receives the signal line 512 when the button pressing signal is supplied through the signal line 535.
The identifier of the document supplied via the is read, and the read identifier is output to the signal line 506. Therefore, the user of the document creation apparatus operates the buttons 30 to 34 of the document search unit 13 when searching for a document,
The code data of the document stored in the code data storage unit 11 is created one by one from the earliest created one or from the most recently created one, either one for editing image or printing image. As display unit 2
2 by pressing the button 35 when the desired document is displayed on the display unit 22,
The identifier of the desired document can be output on signal line 506. That is, a desired document can be searched.

When the button pressing signal is supplied through the signal line 535, the read control section 36 outputs a memory erasing instruction to the signal line 514. The identifier storage unit 41 in the code data reading unit 20 re-initializes the stored value to null when a storage erase command is supplied via the signal line 514. The document editing unit 10 reads the identifier supplied via the signal line 506, reads the code data of the document stored in the code data storage unit 11 via the signal line 507 in association with the read identifier, and newly reads the code data. To be edited. Then, as described above, when the edited document is stored by overwriting the document already stored in the code data storage unit 11, the code data of the edited document is output to the signal line 500 and the signal line 506 is output. The identifier read through is output to the signal line 501. On the other hand, when saving the edited document as a new document, a value null indicating that the document identifier does not exist on the signal line 501 is output.

When the document retrieved by the document retrieval unit 13 is printed, the printing unit 14 reads the identifier supplied via the signal line 506. The printing unit 14 reads the code data of the document indicated by the identifier read through the signal line 506 from the code data storage unit 11 through the signal line 508, generates print image data from the read code data, and prints the image data. To do.

As described above, according to the present embodiment, when the user of the document creating apparatus searches for a document, an editing image for editing the document is displayed or a printing image for printing the document. By using the generated image designating unit 12, it is possible to designate whether to display. For this reason, for example, an image for editing is displayed for a document that has been recently created / edited and the edit screen remains in the memory, and a document that has been printed and saved on paper is modified to create a new document. To create a document, display a print image when searching for a document while comparing it to the printed paper.
It becomes possible to display the image data according to the situation and search the document.

(Second Embodiment) This embodiment relates to the invention of claim 4. The basic structure is the same as that of the first embodiment. Therefore, the description of the same parts is omitted, and only the image data generation part, which is the main part of the present claim, will be described with reference to the drawings. As shown in FIG. 6, the image data generator of this embodiment includes an editing image generator 60,
Print image generation unit 61 and generation image determination unit 63
It is composed of and. Then, these respective units are connected by signal lines 560 to 561.

The generated image determination unit 63 uses the signal line 505.
Read the value supplied via. When the read value is a “false value”, the image data generation command is output to the signal line 560, and the image data generation command is not output to the signal line 561. On the other hand, when the value read through the signal line 505 is the “true value”, the image data generation command is output to the signal line 561 and the image data generation command is not output to the signal line 560.

The editing image generating section 60 uses the signal line 56.
When an image data generation command is supplied via 0,
The code data of the document supplied via the signal line 511 is read, and when the document represented by the code data is edited, the same image data as the image data displayed by the document editing unit 10 is generated, and the generated image data is signaled. Line 5
It outputs to 13.

The printing image generating section 61 uses the signal line 56.
When the image data generation command is supplied via 1,
The code data of the document supplied via the signal line 511 is read, and when the document represented by the code data is printed, the same image data that the printing unit 14 uses for printing is generated, and the generated image data is used as the signal line. Output to 513.

With the above configuration, only one of the editing image generating unit 60 and the printing image generating unit 61 will generate image data, so that the editing image generating unit 60 and the printing image generating unit 61 are When the software is configured by one microcomputer instead of independent hardware, it is possible to shorten the time required to generate the image data as compared with the first embodiment shown in FIG. . (Third Embodiment) This embodiment relates to the inventions of claims 5 and 6.

This embodiment will be described below with reference to the drawings. FIG. 7 is a configuration diagram of this embodiment. In this figure,
Reference numeral 70 is a document editing unit, 71 is a code data storage unit, 72 is a generated image designation unit, 73 is a document retrieval unit, 74 is a printing unit, and 75 is a built-in image generation unit. 75a
Is a print history recording unit inside thereof. Then, these respective units are connected by signal lines 570 to 579.

FIG. 8, FIG. 9 and FIG. 12 are conceptual diagrams showing examples of values representing the history recorded by the print history recording section 75a. The document editing unit 70 has the same basic configuration and operation as those of the first and second embodiments. Therefore, the code data of the edited document also includes print control information as in the first and second embodiments. Similarly, when the edited document is saved as a new document, the code data of the document is output to the signal line 570, and the signal line 571 outputs the value null indicating that the document identifier does not exist. On the other hand, when the code data of the edited document is overwritten on the existing document and stored, the code data of the edited document is output to the signal line 570 and the identifier of the document to be overwritten is output to the signal line 571. Code data storage unit 71
Reads the code data of the document supplied via the signal line 570 and the value supplied via the signal line 571.
If the value read via the signal line 571 is null, a new identifier is added to the code data read via the signal line 570 and stored, and the new identifier added to this code data is stored. Output to the signal line 572. On the other hand, the value read via the signal line 571 is null.
If it is not 1, the read value is used as the document identifier,
Code data read via the signal line 570 is recorded as a document represented by the identifier, and nu is recorded on the signal line 572.
ll is output.

The print history recording section 75a in the operation history recording section 75 of the generated image designating section 72 stores a history of whether or not each document is printed, with respect to the identifier of the printed document. As a table, a "true value" is associated as a value indicating the history, and a "false value" is associated as a value indicating the history with respect to an identifier of a document that is not printed. For example, if there are documents represented by the identifiers A to M, of which the documents of the identifiers A to G have been printed in the past and the documents of the identifiers H to M have not been printed. The identifiers A to G are associated with “true value”, and the identifiers H to M are associated with “false value” and recorded. This state is shown in FIG. The unused columns in the table are
Null is recorded as the identifier, and nothing is recorded in the history value column. The operation history recording unit 75 uses the signal line 572.
Read the value supplied via. If the read value is null, the read value is ignored.
On the other hand, when it is not null, the read value is used as the document identifier, and the document corresponding to the identifier is printed as 1
“False value” is recorded as a value indicating that it has not been done frequently. For example, when the identifier N is further read through the signal line 572 in the state where the history shown in FIG. 8 is recorded, as shown in FIG. 9, at the top of the unused column of the table,
The identifier N and "false value" are recorded in association with each other. The recorded value is updated to the “true value” when the document is printed, and this updating operation will be described in detail later.

It is a block diagram of 01. In FIG. 11, reference numeral 110 is an editing image generation unit, 111 is a printing image generation unit, 112 is a selection unit, and these units are connected by signal lines 610 to 611. Document identification unit 10
The configuration and operation of No. 3 are the same as those of the document specifying unit 23 in the first embodiment.
When compared with, the document identifier is read via the signal line 602 instead of being read via the signal line 512, and the forward document read command and the backward document read command are read on the signal line 5.
10 to the signal line 600 instead of to the signal line 514, and instead of outputting to the signal line 514 a memory erase command.
And output the document identifier on signal line 576 instead of on signal line 506. Therefore, further explanation is omitted.

Similarly, the configuration and operation of the code data reading unit 100 are the same as those of the code data reading unit 2 in the first embodiment.
When compared with 0, the code data of the document is transferred to the signal line 50.
3 instead of reading through signal line 511 and outputting to signal line 511, reading through signal line 573 and outputting to signal line 601 and reading the document identifier through signal line 504 and outputting to signal line 512. The data is read out via the line 574 and outputted to the signal line 602, and the forward document read command and the backward document read command are supplied via the signal line 600 instead of being supplied via the signal line 510, and the memory erase command is issued. It is exactly the same except that it is supplied via the signal line 604 instead of being supplied via the signal line 514. Therefore, further explanation is omitted.

The editing image generating section 110 in the image data generating section 101 reads the code data of the document supplied via the signal line 601, and when the document editing section 70 edits the document represented by the code data. The same image data as the image data to be displayed is generated, and the generated image data is output to the signal line 610. The printing image generation unit 111 reads the code data of the document supplied via the signal line 601, and generates the same image data that the printing unit 74 uses for printing when printing the document represented by the code data. , And outputs the generated image data to the signal line 611.

The selector 112 reads the document identifier supplied via the signal line 602. The selection unit 112 further reads, via the signal line 575, the value recorded in association with the read identifier among the values indicating the history recorded in the print history recording unit 75a. Signal line 5
When the value read via 75 is a “false value”, the image data supplied via the signal line 610 is read and the image data is output to the signal line 603. The image data supplied via the signal line 611 is ignored. On the other hand, when the read value is the “true value”, the image data supplied via the signal line 611 is read and the image data is output to the signal line 603. The image data supplied via the signal line 610 is ignored. For example, when the print history recording unit 75a is recording the history as shown in FIG. 9, if the identifier of the document supplied through the signal line 602 is H to N, the document is supplied through the signal line 610. Output the image data to the signal line 603,
If the document identifier is A to G, the image data supplied via the signal line 611 is output to the signal line 603.

The display unit 102 displays only one piece of image data lastly supplied via the signal line 603. The document identifying unit 103 identifies the identifier of the document displayed on the display unit 102 as the identifier of the document to be searched by the user based on the operation of the user of the document creating apparatus, and assigns it to the signal line 576. Output.

The document editing unit 70 reads the identifier supplied via the signal line 576, and associates the code data of the document recorded in the code data storage unit 71 with the read identifier via the signal line 577. Read and make a new edit target. The document editing unit 70 outputs the identifier read via the signal line 576 to the signal line 571 when overwriting and saving the edited document on the document already stored in the code data storage unit 71. On the other hand, when saving the edited document as a new document, a value null indicating that the document identifier does not exist on the signal line 501 is output.

When printing the document retrieved by the document retrieval section 73, the printing section 74 reads the identifier supplied via the signal line 576. The printing unit 74 reads the code data of the document indicated by the identifier read through the signal line 576 from the code data storage unit 71 through the signal line 578, generates the print image data from the read code data, and prints it. To do. The printing unit 74 prints the document and then outputs the identifier supplied through the signal line 576 to the signal line 5
Output to 79. Signal line 5 if the document is not printed
Outputs null to 79.

The print history recording unit 75a reads the value supplied via the signal line 579, and the read value is null.
When it is l, the read value is ignored. On the other hand, when the value read via the signal line 579 is not null, the read value is used as the document identifier, and the value indicating the history recorded in association with the identifier is updated to the “true value”. For example, if the identifier N is supplied via the signal line 579 when the recorded history is in the state shown in FIG. 9, as shown in FIG. 12, the value representing the history corresponding to the identifier N is “ True value ”. On the other hand, even when the identifier A is supplied via the signal line 579, the value representing the history corresponding to the identifier A is updated to the “true value”, but it is recorded in association with the identifier A before the update. Since the value representing the history is already the "true value", no substantial change occurs.

In this way, the print history recording section 75a
For each of the code data of the documents stored in the code data storage unit 71, “true value” is recorded for the identifier of the document printed in the past, and the identifier of the document that has never been printed. "False value" can be recorded for. According to the document creating apparatus of this embodiment, the print history recording section 75a in the generated image designating section 72 records a history of whether or not each document is printed, and the user of the document creating apparatus writes the document. When retrieving a document, the print history recording unit 7 determines whether to display an edit image for editing a document or a print image for printing a document.
It is determined using the history recorded by 5a. For this reason,
For documents that have been printed, a printing image with many visual characteristics such as bag binding and multi-column printing is displayed, and it is difficult for the user to assume the printing image. As a result, it becomes possible to display the same editing image that the user saw on the editing screen when editing the document. (Fourth Embodiment) This embodiment relates to the inventions of claims 7 and 8, and its basic configuration is the same as that of the third embodiment. FIG. 13 is a configuration diagram of a main part of a different part. In the figure, 102a is a print image display unit,
Reference numeral 132 is a generation image designation unit, 135 is an operation history recording unit, 135a is a display history recording unit therein, and 630 is a signal line. The document creating apparatus of the present embodiment is different from the document creating apparatus of FIG. 7 in that the printing image display section 102a and the signal line 630 are added, the generated image designating section 72 is replaced with the generated image designating section 132, and Print history recording unit 75a in the operation history recording unit
Is different from the print image display history recording section 135a.

In the present document creating apparatus, the user of the document creating apparatus uses the printing image display section 102a to display how the document is printed before actually printing the document using the printing section 74. It can be displayed and confirmed.
The procedure for displaying and checking in advance how a document will be printed is as follows.

The printing image display unit 102a reads the document identifier supplied via the signal line 576. The print image display unit 102a displays the code data of the document indicated by the identifier read via the signal line 576 on the signal line 5
It is read from the code data storage unit 71 via 78, and the print image data is generated from the read code data and displayed. The display device itself (not shown) for this purpose is composed of a CRT and a liquid crystal display which are also used as the text editing unit 70 and the like. The printing image display unit 102a generates and displays the printing image data of the document, and then outputs the identifier supplied through the signal line 576 to the signal line 630. When the document print image data is not generated and displayed, nu is input to the signal line 630.
ll is output.

Printing image display history recording section 135a
Performs exactly the same operation as the print history recording section 75a shown in FIG. 7 in the third embodiment for the value supplied via the signal line 572 and the signal line 579. The print image display history recording unit 135a further reads the value supplied via the signal line 630, and the read value is null.
If it is 1, the read value is ignored. On the other hand, when the value read via the signal line 630 is not null, the read value is used as the document identifier, and the value indicating the history recorded in association with the identifier is updated to the “true value”.

The construction operation of the other components is shown in FIG.
Since it is exactly the same as the document creating apparatus shown in FIG. According to the present exemplary embodiment, even if the document is not a document that has been printed in the past, a document in which the searcher has viewed the printing image using the printing image display unit 102a has a memory,
It is not an image for editing when editing a document, but a bag binding,
It becomes possible to search a document by displaying a printing image having more visual characteristics such as a column. In addition, after generating the image data for printing,
This data may be output to a storage medium for display on another external device. In such a case, the same measure can be taken by providing a print image generation history recording unit instead of the print image display history recording unit.

Although the present invention has been described above based on the embodiments, it goes without saying that the present invention is not limited to the above embodiments. That is, for example, the following items are also included in the present invention. (1) In the first embodiment, the document search device is integrated into the document creation device, but it is a pure document search device having no document editing unit. Further, although the document creation device has the printing unit, when printing a document, the code data stored in the code data storage unit is once copied to a medium such as a floppy disk and the code data is copied to the medium. It is read by another device having a printing function via the device, and printing is performed using the other device. The printing image generation unit enables high-speed display by generating image data having a resolution lower than that of the image data printed by the printing unit, thereby speeding up the search. This effect will be great especially when the user searches for a document created by himself as a material many times. The edit image generation unit is not owned by the image data generation unit independently, but is also used by the document edit unit when the document edit unit displays the document being created on the display unit for the user. As a concrete means for this, a memory in which software for creating image data for editing from code data of a document is incorporated is shared.

Similarly, the print image generating section is not held independently by the image data generating section, but is shared with the one used when the printing section prints a document. The cycle at which the read control unit outputs the forward read command or the backward read command depends on the skill of the user, the visibility of the image data, or the time required to create the image data from the code data of the document. It is set to another value other than 0.2 seconds. In addition, it can be changed to 0.5 seconds, 1 second, etc. by using a changeover switch or the like. The order in which the reading unit reads the document from the code data storage unit is not determined based on the time when the document was created, but is determined based on another order, for example, based on the time when the document was last updated, or Documents specified by the specifying unit a large number of times, that is, documents having a large number of times targeted for retrieval may be displayed first. In the latter case, it may be convenient in terms of software to use the learning function technology when converting Kanji in a word processor. The buttons of the document specifying unit, 30, 33 and 34, and the function of the read control unit to periodically output the forward read command and the backward read command to the signal line 510 are omitted, and the user of the document creating apparatus sets a predetermined value. This is realized by the code data reading unit reading the code data of the document from the code data storage unit only when the button is pressed. For each button in the document specifying section, an icon is displayed on the display section adopting a multi-window system, and the icon is selected by a pointing device such as a mouse or a light pen. This will reduce the manufacturing cost of hardware. The display unit does not display only one piece of image data generated last by the image data generation unit, but simultaneously displays a plurality of image data, and the document specifying unit selects an instruction such as a mouse or a light pen from among them. The document identifier represented by the image data displayed by the tool is output. If the document stored in the code data storage unit has a plurality of pages per document, the document reading unit reads only the code data of the first page of the document. Alternatively, when the forward read command is supplied through the signal line 510, the document is read one page at a time starting from the first page of the document to the last page, and the backward read command is supplied through the signal line 510. In this case, the pages are read one by one from the last page of the document to the first page.

(2) In the fourth embodiment, the function of generating the printing image data of the printing unit and the function of generating the printing image data of the printing image display unit are shared,
Further, instead of outputting the document identifier to the printing image display history recording unit from the printing unit and the printing image display unit via signal lines independent of each other, the signal lines are gathered into one and shared on this. When the printing image data is generated by the function of generating the printing image data, the document identifier is output to the printing image display history recording unit via the signal line combined into one line.

(3) When a large number of documents are constantly created at the same time, such as research papers in university laboratories and application documents in patent offices, etc. For the convenience of creating the document, a function is added to display only the last page of the document being created or this and the previous page. In this case, the image data will often be displayed as edit image data.

(4) In the invention of each claim, a long document is added with a function of treating it as one document in units of 10 pages. With this,
In particular, when using long texts, long research papers, and the like, the search efficiency of the necessary place using the image data for editing is further improved. It should be noted that for the above-described application example, a document identifier is also used for each page instead of each document, so to speak, a small identifier is adopted, and a history value is created for every 10 pages or according to a printing mode. Needless to say, necessary corrections such as the history values are made.

(5) When generating the printing image data from the code data of the document, the printing image data is generated within 0.2 seconds shown in the embodiment depending on the processing capacity of the printing image data generating section. It may be difficult to generate, and it may be difficult to display the contents in a flipping manner. In this case, the image data for printing is generated in advance only for such a document and then stored as image data in a separately provided storage unit. C for documents that take time to generate print image data
The display on the RT is postponed. As a result, the number of documents displayed within a certain period of time from the start of display increases, and it is likely that documents to be searched are displayed in those documents, which improves the search speed. Generating an editing image often requires less time than generating a printing image. Therefore, the document displayed as the editing image is displayed first, or while the document is being displayed, the printing image of the document displayed as the printing image is generated and stored in the buffer. Depending on the type of image to be generated, devise the display order of documents, the generation timing of print images, and the temporary storage.

(6) In recent years, various types of print image data such as different fonts and different colors can be designated for the same document. Further, although the actual printing is achromatic due to the function of the printing machine and the like, the input code data may be chromatic. Therefore, the designation of the print image data to be displayed in the page turning mode is appropriately selected in accordance with these functions and the printing mode.

(7) It goes without saying that the document referred to in the present invention is not limited to a pure document consisting of only characters. For example, it includes a part of which includes a figure, or one page which includes a figure. (8) Furthermore, for the convenience of manufacturing, the constituent elements (requirements) essential to the invention of each claim are physically plural elements. Conversely, several essential components are physically integrated. Alternatively, these divisions and merges are appropriately combined.

The operation and effect of the present invention can be achieved by modifying an existing word processor or newly installing a floppy disk or the like in which the program of the present invention is incorporated. (9) When the number of documents to be searched is huge, other search keys such as vertical writing or horizontal writing, user name, creation date, document name, etc. are also used as primary search means. In addition, it has a plurality of display units, and a plurality of users can search at the same time.

[0073]

As described above, according to the present invention,
Image (image) used when retrieving a document in a page-turning mode As the content and type of the page surface that has been converted to data, use the editing image displayed when editing the document, or use it for printing when printing the document. Whether to use an image
It can be determined according to the user's instruction or the operation history performed on each document. Therefore, a document as an image suitable for the search is generated from the code data and displayed, and the search efficiency is improved.
