Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document storage / retrieval method and document for inputting and storing a document as a set of character code data and control code data or a set of bitmap image data, and displaying the same on a screen for retrieval. The present invention relates to a storage / retrieval device.

[0002]

2. Description of the Related Art Generally, a document storage / retrieval device is realized as a word processor or an electronic filing system. As a document search method in such a document storage / retrieval device, there are many methods that make a rational search possible by adding a keyword at the time of document registration. However, since this keyword assignment work is complicated, a simpler document retrieval method is required.

Therefore, recently, a document storage / retrieval device has been adopted in which a document is sequentially displayed on the screen page by page (hereinafter, referred to as "page turning display") without adding the keyword, thereby performing a visual search. Has appeared. A conventional document storage / retrieval apparatus that employs such a page-turning display retrieval method includes a document input unit 31, a document storage unit 32, a document reading unit 33, and a high-speed buffer unit 34, as shown in FIG. , Document display search unit 3
5 and. The document input unit 31 inputs document data. The document storage unit 32 is composed of, for example, a flexible disk having a low access speed, and stores the document data from the document input unit 31. The document reading unit 33 reads the document data from the document storage unit 32 and outputs the document data to the high-speed buffer unit 3
Transfer to 4. The high speed buffer unit 34 is composed of, for example, a DRAM having a high access speed, and stores the document data from the document reading unit 33. The document display search unit 35 causes the user to search for the desired content by page-displaying the document data read from the high-speed buffer unit 34.

FIG. 15 is an explanatory diagram of the structure of document data in the document storage unit 32 when two documents are input and stored in the conventional document storage / retrieval device. FIG. 16 is an explanatory diagram of display contents of the document display search unit 35. In this conventional document input storage / retrieval device, each document is composed of one page, and the retrieval is performed by visually observing the displayed document. Document 1 is composed of a table composed of ruled lines and characters for filling the table. Document 2 is composed of a map of roads and buildings composed of line drawings and characters showing roads and buildings. . Further, it is assumed that the document 2 is searched as the target document. First, the document input section 3
1 inputs the two documents shown in FIG. Next, the document storage unit 32 stores the document data from the document input unit 31 for each document. As shown in FIG. 15, it is assumed that the data capacity of both document 1 and document 2 is 1 KB. Next, the document reading unit 33 reads the document data of the document 1 from the document storage unit 32 and transfers it to the high-speed buffer unit 34 in order to search for the document. Next, the document display search unit 35 reads the document data in the high speed buffer unit 34 and displays it as shown in FIG. Since the target document is document 2, the user does not perform a predetermined search end operation. Therefore, the document reading unit 33 next reads the document data of the document 2 from the document storage unit 32, and the high-speed buffer unit 34
Transfer to. Next, the document display search unit 35 reads the document data in the high speed buffer unit 34 and displays it as shown in FIG.

Here, the time at which the document data is read out from the document storage unit 32 for display is set as a reference time and 1K.
If it takes 2 seconds to read B and transfer it to the high-speed buffer unit 34, and the time for reading and displaying B from the high-speed buffer unit 34 is negligible, as shown in FIG. The document 1 is displayed 2 seconds after the time, and the document 2 is rewritten 4 seconds after the reference time. The user can identify the target document 2 4 seconds after the reference time by visually observing this display.
However, the time from when the document is displayed until it is specified can be ignored.

[0006]

However, in the above-mentioned conventional configuration, since the document data is not displayed until the document data is completely read out from the document storage unit 32 whose reading speed is slow, it takes time until the target document, for example, the document 2 is displayed. Therefore, there is a problem that high-speed page turning display and search cannot be performed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a document storage / retrieval method and a document storage / retrieval device that can perform high-speed page turning retrieval even when a low-speed storage device is used. .

Embodiments of the present invention will now be described in detail with reference to the drawings. (Embodiment 1) FIG. 1 is a block diagram of a document storage / retrieval apparatus according to a first embodiment of the present invention. This document storage / retrieval apparatus includes a document input unit 1, a document hierarchy unit 2, a document storage unit 3, Document reading unit 4, high-speed buffer unit 5, document display search unit 6
It has and. The first embodiment corresponds to claims 1 and 2. The document input unit 1 inputs document data. The document layering unit 2 uses, for example, ruled lines, based on a visual point of view.
The document data from the document input unit 1 is hierarchized by dividing it into line drawings, double-width characters, and other characters. The document storage unit 3 is composed of, for example, a flexible disk having a low access speed, and stores the document data from the document hierarchy unit 2
Save it in a format that can be accessed by dividing it into layers. The document reading unit 4 reads the document data from the document storage unit 3 and transfers it to the high speed buffer unit 5. High-speed buffer unit 5
Is composed of, for example, a DRAM having a high access speed, and stores the document data from the document reading unit 4. The document display search unit 6 causes the user to search for the desired content by page-displaying the document data read from the high-speed buffer unit 5.

FIG. 2 is an explanatory diagram of the structure of the document data in the document storage unit 3 when two documents are input and stored in the document storage / retrieval apparatus. 3 and 4 are explanatory diagrams of display contents of the document display search unit 6. Next, the operation of the document storage / retrieval apparatus will be described with reference to the flowchart of FIG. Now each document consists of one page,
The search is performed by the user visually observing the document displayed by the document display search unit 6. Also, document 1
Is composed of a table composed of ruled lines and characters filling the table, and the document 2 is composed of a map of roads and buildings composed of line drawings and characters showing roads and buildings. Further, it is assumed that the document 2 is searched as the target document.

First, the document input unit 1 inputs two documents as shown in FIG. 4 (step S1). Next, the document hierarchy unit 2
However, after the document data from the document input unit 1 is hierarchized based on a visual point of view, that is, by dividing it into ruled lines, line drawings, double-width characters and others and others (step S
2) As shown in FIG. 2, the document is stored in the document storage unit 3 in a format that can be accessed separately for each layer (step S3). In the first embodiment, ruled lines, line drawings, and double-width characters are applied as layer 1, and the rest are layer 2. As shown in Figure 2,
The data capacity of layer 1 of document 1 and document 2 is 0.5
The data capacities of KB and Tier 2 are 0.5 KB each. Next, the document reading unit 4 reads the document data of the layer 1 of the document 1 from the document storage unit 3 in order to search for the document (steps S4 and S5) and stores it in the high speed buffer unit 5. Next, the document display search unit 6 changes the high speed buffer unit 5
The document data of the layer 1 of the upper document 1 is read and displayed as shown in FIG. 3 (A) (step S6). That is, in the document 1, only double-width characters and ruled lines are displayed. Since the target document is document 2, the user does not perform the search end operation at this stage (N in step S7).
O). Therefore, the document reading unit 4 reads the document data of the layer 1 of the document 2 from the document storage unit 3 (step S
8, S9, S5), and stored in the high speed buffer unit 5. Next, the document display search unit 6 reads the document data of the layer 1 of the document 2 on the high-speed buffer unit 5 and displays it as shown in FIG. 3B (step S6). That is, in the document 2, only double-width characters and line drawings are displayed. Since the target document is the document 2, when the user performs a predetermined search end operation (YES in step S7), the search operation ends.

When the user does not perform the search end operation (NO in step S7), the document reading unit 4 reads the document data of the layer 2 of the document 1 from the document storage unit 3 (steps S8, S10, S11, S12). , S5), and stored in the high speed buffer unit 5. Next, the document display search unit 6 reads both the data of the layer 1 and the layer 2 of the document 1 on the high-speed buffer unit 5 and displays them as shown in FIG. 4A (step S6). Further, when the user does not perform the search end operation (NO in step S7), the document reading unit 4
However, the document data of the layer 2 of the document 2 is read from the document storage unit 3 (steps S8, S9, S5) and stored in the high speed buffer unit 5. Next, the document display search unit 6 reads both the data of the layer 1 and the layer 2 of the document 2 on the high-speed buffer unit 5 and displays them as shown in FIG. 4B (step S6).

Here, it takes 2 seconds to read 1 KB and transfer it to the high-speed buffer unit 5 with the time when the document reading unit 4 starts reading the document data from the document storage unit 3 for display as a reference time. Assuming that the time read out from the unit 5 and displayed is so small that it can be ignored, as shown in FIG. 3, the document display retrieval unit 6 displays the document data of the layer 1 of the document 1 one second after the reference time. It is rewritten to the data of the layer 1 of the document 2 2 seconds after the time. Further, as shown in FIG. 4, the document data of the layer 1 and the layer 2 of the document 1 are rewritten 3 seconds after the reference time, and the document data of the layer 1 and the layer 2 of the document 1 are rewritten 4 seconds after the reference time. Therefore, the user can identify the target document 2 two seconds after the reference time by visually observing this display. However, the time from when the document is displayed until it is specified can be ignored.

As described above, since the document can be specified only by the information of the layer 1, the time for specifying the target document 2 from the two documents can be shortened. In other words, when saving the document data, the information that has a high degree of contribution to the search is saved in several stages in order, and the page data is displayed in order from the document data in the higher order, and the display information is gradually increased.
A high-speed page turning search can be performed even by using the low-speed document storage unit 3.

In the first embodiment described above, ruled lines, line drawings, and double-width or larger characters are selected as the layer 1, but of course, other characters may be used, and the selection method from the visual viewpoint for layering is not limited. Not something. Further, in the first embodiment described above, the number of layers is divided into two, but the number of layers is not limited to two and can be set arbitrarily. When the number of layers is large, it is not always possible to specify a document only with information of layer 1, but it is possible to specify a document only with information of a relatively higher layer, and the document search time is reduced. Can be shortened well. (Embodiment 2) FIG. 6 is a block diagram of a document input storage / retrieval apparatus according to a second embodiment of the present invention. This document input storage / retrieval apparatus includes a document input unit 11, a document area separation unit 12, and a document storage unit 13. , Document reading unit 14, high-speed buffer unit 1
5 and a document display search unit 16. The second embodiment corresponds to claims 3 and 4. The document input unit 11

Reference numeral 3 is composed of, for example, a flexible disk having a low access speed, and stores the document data from the document area separating unit 12 in a format that can be accessed by dividing it into display areas. The document reading unit 14 reads the document data from the document storage unit 13 and transfers it to the high speed buffer unit 15. The high speed buffer unit 15 is composed of, for example, a DRAM having a high access speed, and stores the document data from the document reading unit 14.
The document display search unit 16 turns the document data read from the high-speed buffer unit 15 into pages, and causes the user to search for desired contents.

FIG. 7 is an explanatory diagram of the structure of the document data in the document storage unit 13 when two documents are input and stored in the document storage / retrieval device. 8 and 9 are explanatory diagrams of display contents of the document display search unit 16. Next, the operation will be described. Note that the flowchart is almost the same as that in FIG. Now, each document consists of one page, and the search is performed by visually observing the displayed document. Also, document 1
Is composed of a table composed of ruled lines and characters filling the table, and the document 2 is composed of a map of roads and buildings composed of line drawings and characters showing roads and buildings. Further, it is assumed that the document 2 is searched as the target document.

First of all, the document input section 11 operates as shown in FIG.
Input the two documents shown in (B). Next, the document area separating unit 12 separates the document data from the document input unit 11 into display areas, and then, as shown in FIG.
Each area is saved in a format that can be accessed. In the second embodiment, the upper half of the document is applied as the area 1 and the rest is the area 2. As shown in FIG. 7, the data capacity of area 1 of document 1 and document 2 is 0.5 KB and area 2 respectively.
The data capacity of each is 0.5 KB. Next, the document reading unit 14 reads the document data in the area 1 of the document 1 from the document storage unit 13 and transfers it to the high-speed buffer unit 15 in order to search for the document. Next, the document display search unit 16
Reads the document data on the high-speed buffer unit 15,
It is displayed as shown in FIG. That is, only the upper half of the document 1 is displayed. Since the target document is document 2, the user does not perform the search end operation at this stage. Therefore, the document reading unit 14 is replaced by the document storage unit 1.
The document data in the area 1 of the document 2 is read from the document 3 and transferred to the high speed buffer unit 15. Next, the document display search unit 16
By reading the document data on the high-speed buffer unit 15,
(B) is displayed. That is, only the upper half of the document 2 is displayed. Since the target document is the document 2, when the user performs a predetermined search end operation, the search operation ends.

When the user does not perform the search end operation, the document reading unit 14 reads the document data of the area 2 of the document 1 from the document storage unit 13 and transfers it to the high speed buffer unit 15. Next, the document display search unit 16 changes the high-speed buffer unit 15
Data in both area 1 and area 2 of the above document 1 are read and displayed as shown in FIG. Next, the document reading unit 14 reads the data in the area 2 of the document 2 from the document storage unit 13 and transfers it to the high speed buffer unit 15. Next, the document display search unit 16 reads both data of the area 1 and the area 2 of the document 2 on the high-speed buffer unit 15 and displays them as shown in FIG. 9B.

Here, the time to start reading the document data from the document storage unit 13 for display is set as a reference time and 1K.
If it takes 2 seconds to read B and transfer it to the high-speed buffer unit 15, and the time to read and display from the high-speed buffer unit 15 is small enough to be ignored, the document display search unit 16 has a standard as shown in FIG. The document data in the area 1 of the document 1 is displayed 1 second after the time, and is rewritten to the document data in the area 1 of the document 2 2 seconds after the reference time. Further, 3 seconds after the reference time, the document data in the area 1 and the area 2 of the document 1 are rewritten, and 4 seconds after the reference time, the document data in the areas 1 and 2 of the document 2 are rewritten. Therefore, the user can identify the target document 2 two seconds after the reference time by visually observing this display. However, the time from when the document is displayed until it is specified can be ignored.

As described above, since the document can be specified only by the information of the layer 1, the time for specifying the target document 2 from the two documents can be shortened. That is, when the document data is saved, the document data is saved in several stages, the page data is displayed in order from the higher order document data, and the display information is gradually increased. A high-speed page turning search can be performed.

In the second embodiment, the regions are separated into upper and lower parts. However, it is not always necessary to constitute such a structure, and the left and right regions are separated, the central part and the peripheral part are separated, or the user inputs the document. May be configured so as to be separated from the area set to be important and other areas. In the second embodiment, the area is divided into two, but the number of areas is not limited to two and can be set arbitrarily.
When the number of areas is large, it is not always possible to specify the document only with the information of the area 1, but it is possible to specify the document only with the information of a relatively high area, and the document search time is reduced. Can be shortened well. (Third Embodiment) FIG. 10 is a block diagram of a document input storage / retrieval apparatus according to the third embodiment of the present invention. This document input storage / retrieval apparatus includes a document input unit 21, a document color data separation unit 22, and a document storage unit. 23, a document reading unit 24, a high-speed buffer unit 25, and a document display search unit 26.

Next, the document display search unit 26 reads the monochrome data and the color data of the document 2 on the high speed buffer unit 25,
It is displayed as shown in FIG.

Here, the time at which the document data is read out from the document storage unit 23 for display is set as a reference time and 1K.
If it takes 2 seconds to read B and transfer it to the high-speed buffer unit 25, and the time for reading and displaying B from the high-speed buffer unit 15 is negligible, as shown in FIG. The monochrome data of the document 1 is displayed 1 second after the reference time, and the monochrome data of the document 2 is rewritten 2 seconds after the reference time. Furthermore, FIG.
As shown in FIG. 3, the monochrome data and the color data of the document 1 are rewritten 3 seconds after the reference time, and the monochrome data and the color data of the document 1 are rewritten 4 seconds after the reference time. Therefore, the user can identify the target document 2 two seconds after the reference time by visually observing this display. However, the time from when the document is displayed until it is specified can be ignored.

It should be noted that black and white stage display may be used instead of color. In this way, since the document can be specified only with the monochrome information, the time for specifying the target document 2 from the two documents can be shortened.
