When the desired page is displayed during page turning, the stop key is operated to confirm the displayed page, and assuming that this page is the desired page, the page remains stationary without changing to the next page. It is what makes me. Alternatively, with respect to this page, the search processing is further performed for the data forming the page.

The database storage unit 107 records character data, graphic data, and photographic data, which form electronic information divided for each page, in a predetermined storage area. An example of a conceptual diagram showing the stored contents of the database storage unit 107 is shown in FIG.
Shown in. As shown in FIG. 3, each address stores data for each type, that is, character data, graphic data, and photograph data. For example, the address "0" indicates that the character data "AIUEOKAKIKUKEKO ..." Is stored. In addition, in FIG. 3, the character data, the graphic data, and the photograph data are represented by simple characters and pictures.
This is only shown for the sake of convenience. Actually, character data is stored as, for example, a character code, bitmap data, etc., and in the case of graphic data, it is stored as, for example, coordinate data, bitmap data, etc. In the case of
It is stored as bitmap data or the like.

The table-of-contents data storage unit 108 stores a document table and a reference table. The document table stores what data is stored in each page of electronic information. An example of this document table is shown in FIG. In FIG. 4, the document page column stores the identification number of the electronic information page. The data address column stores the address of the data stored in the page of the identification number stored in the document page column of the same row.
For example, the data forming the page with the identification number A-2 is
It indicates that the data is stored in the address “3”, the address “4”, and the address “5”.

The reference table is stored in the database storage unit 10.
7 stores the type of data, the address of the data in the database storage unit 107, and the information indicating which page is used in the electronic information. An example of this reference table is shown in FIG. In FIG. 5, the data address column stores the address of the data as in the case of the above-mentioned document table. The identifier column and the reference document page column store the data type stored in the address stored in the same-stage data address column, the identifier column stores the type of the data, and the reference document page column stores the data type. The identification number of the page using the data is stored. For example, the address "2" is of type photo data,
It is shown that they are used for pages A-2 and C-2.

The address processing unit 102 extracts all data of that type from the database storage unit 107 according to the type of search target input from the input unit 101. Specifically, the address processing unit 102 includes an address addition unit, an address extraction unit, and a subsequent address determination unit. The address addition unit generates numerical information that is a trigger for extracting the addresses of the search target type data from the table of contents data storage unit 108 in the stored order and also specifies the numerical information, and the address addition unit in the subsequent stage. Output to. Specifically, this address addition unit receives an instruction of “start search” from the input unit 101. Then, this address addition unit stores the extraction order “1”. Here, the extraction order indicates the order in which the search target type data stored in the table of contents data storage unit 108 is stored. Next, the extraction order “1” is output to the address extraction unit in the subsequent stage. Also, each time a signal indicating a "type data extraction start" instruction from the subsequent address determination unit in the subsequent stage is received, "1" is added to generate and store the extraction order, and this extraction order is stored in the subsequent address extraction unit. Output to.

The address extraction unit extracts the address of the data of the search target type from the table of contents data storage unit 108 according to the extraction order input from the address addition unit, and outputs it to the subsequent stage. Specifically, the search target type is received from the input unit 101. Then, each time the extraction order is received from the address addition unit, the identifier column in the reference table is searched to find out the identifier of the search target type whose storage order is the extraction order, and is associated with the found identifier. Extract the address. Then, the subsequent data processing unit 103
Output to. Further, thereafter, this address extraction unit outputs the search target type and the extraction order to the subsequent address determination unit in the subsequent stage.

The subsequent address determination unit receives the search target type and the extraction order from the address extraction unit. And
Each time these signals are received, these are used to determine whether or not the address extraction unit has extracted all search target types from the database storage unit 107. In particular,
Each time the subsequent address determination unit receives the search target type and the extraction order from the address extraction unit, it generates a numerical value obtained by adding 1 to the extraction order. Then, among the identifiers of the search target type in the reference table of the table of contents data storage unit 108,
An identifier whose number is the stored order is searched out. If there is an identifier, it is determined that "all search target types have not been extracted", and a "type data extraction start" signal is output to the address addition unit. On the other hand, if there is no identifier, it is determined that "all search target types have been extracted", and a "type data output completion" signal is output to the display unit 109.

The data processing unit 103 is the address processing unit 1
When the address is received from the address extracting unit 02, the database storage unit 107 is searched, the data of the address is extracted and output to the display unit 109 in the subsequent stage. The data processing unit 103 also has a buffer, and temporarily stores the address. By doing so, the input unit 101
Therefore, when the stop key is operated that the data currently displayed on the display unit 109 is the data desired by the operator, the page processing unit 105 at the subsequent stage searches in this buffer, The address of the data displayed on the display unit 109 can be known.

The data designating section 104 designates data desired by the operator, searches for pages using the data, and outputs these pages to the subsequent stage. Specifically, when an operator's stop instruction is received from the input unit 101, an interrupt signal for stopping the processing of the address processing unit 102 is output. Further, the address of the currently displayed data is read from the buffer of the data processing unit 103. Then, the reference table of the table-of-contents data storage unit 108 is searched to read the identification number of the page stored in association with this address. Then, the read data is output to the subsequent page processing unit 105.

The page processing section 105 includes a data designating section 10
In order to display on the display unit 109 all pages (hereinafter referred to as candidate pages) including the data of the type desired by the operator among the pages received from the page 4, that is, the electronic information,
These pages are extracted and output to the display unit 109. Specifically, the page processing unit 105 includes a page addition unit, a page extraction unit, and a subsequent page determination unit.

Even if there are a plurality of received pages (candidate pages), the page addition unit outputs numerical information (hereinafter, referred to as output order) for outputting all of the plurality of candidate pages to the display unit 109 in the subsequent stage. To generate. Specifically, when the candidate page is received from the data designating unit 104, the output rank “1” is generated and the output rank is output to the page extracting unit in the subsequent stage. Here, the output rank “1” indicates the first candidate page received from the candidate pages received from the data designation unit 104.
Next, each time the instruction of “start page extraction” is received from the type page determination unit in the subsequent stage, the output rank is generated by adding “1” and is output to the page extraction unit in the subsequent stage.

Each time the page extraction unit receives the output rank from the page addition unit, the page extraction unit finds out from the received candidate pages a candidate page according to the output rank input from the page addition unit. Then, the contents data storage unit 108 is searched,
The address of the data forming the candidate page thus found is extracted and output to the display unit 109. Further, thereafter, this page extraction unit outputs the candidate page and the output rank received from the data designation unit 104 to the subsequent page determination unit in the subsequent stage.

The subsequent page determination unit receives the candidate page and the output rank from the page extraction unit. Then, each time the information is received, the information is used to determine whether or not the page extraction unit has extracted the above data for all candidate pages. Specifically, when the candidate page and the output rank are received from the page extraction unit from the page extraction unit, there is a candidate page in which the order of the numerical value obtained by adding 1 to the numerical value of the output rank is the received order. Determine whether or not. If you have a candidate page,
"The page extractor is still
It is determined that "data extraction has not been performed", and a "page extraction start" signal is output to the page addition unit. On the other hand, if there is no candidate page, it is determined that “the page extraction unit has extracted data for all candidate pages” and outputs a signal indicating “page output end” to the display unit 109 in the subsequent stage.

When the page designation unit 106 receives a stop instruction from the input unit 101, the page designation unit 106 outputs an interrupt signal for ending the processing of the page processing unit 105. Display unit 109
Displays characters, figures, or photographs according to the data received from the data processing unit 103. Also, the page processing unit 10
The page data is displayed according to the page data received from the page 5. Further, when a signal indicating "completion of type data output" from the data processing unit 103 or a signal indicating "end page output" from the page processing unit 105 is received, data or page desired by the operator can be included. A message indicating "no data to display" indicating that all relevant data or pages have been displayed is displayed.

The operation of the search device having the above configuration will be described below with reference to FIG.
8 and the flowchart of FIG. Further, in this description, a specific example will be used to explain in a timely manner. As a specific example, the search target is electronic information indicated by the data in FIGS. 3 and 4. The desired page is the page with the identification number C-2 shown in FIG.
And the figure shown on the page is known,
It is assumed that this figure is a key for finding out a desired page.

First, the input unit 101 inputs a search start instruction, and then inputs the type of search target (“graphic” in the specific example) (S100). Then, the address processing unit 102 checks whether or not there is a search target type identifier stored in the table of contents data storage unit 108,
If so, of the identifiers of the search target type stored in the table-of-contents data storage unit 108, the first stored identifier is searched out and the address of that identifier is extracted (S1).
01-S104). Next, by the data processing unit 103,
The data of the address is extracted from the database storage unit 107 and displayed on the display unit 109 (S105).

Specifically, after the input unit 101 gives an instruction to start the search, the search object type "graphic" is input. Then, the identifier "graphic" stored in the second row is searched from the reference table in FIG. 5, and the address "1" is extracted. Then, the corresponding graphic data is extracted from the database storage unit 107 of FIG.
9 is displayed.

After displaying the data, it is determined whether there is a stop instruction from the input unit 101 (S106). If not, the subsequent address determination unit of the data processing unit 103 determines whether or not there is data of the search target type that has not been displayed (hereinafter referred to as subsequent data) (S107, S108). As a result, if it is determined that there is subsequent data, the contents of the table of contents data storage unit 1
Of the identifiers of the search target type stored in 08, the extracted identifier is assumed to be stored second (S109), and the address of that identifier is extracted. Then, similarly to the above, the data processing unit 103 extracts the data of the address and displays it on the display unit 109.
Thereafter, the above processing is repeated while changing the order of the identifiers extracted from the table-of-contents data storage unit 108 until the stop instruction from the input unit 101 or the subsequent address determination unit determines that there is no subsequent data, and the display unit displays the search target. The data of the type is displayed one after another.

On the other hand, when the succeeding address judging unit judges that there is no succeeding data, the succeeding address judging unit outputs a signal to the display unit 109 to display a message indicating "no data to be displayed" on the display unit 109. Is displayed (S110), and the page turning operation is completed. On the other hand, when there is a stop instruction from the input unit 101, the data designating unit 104 stops the page turning operation of the data of the search target type, and the next candidate page turning process (S1
Go to 11).

Specifically, the data address "1" of the search object type "graphic" stored first is extracted from the identifiers of the search object type "graphic" stored in the reference table of FIG. It Then, the graphic data of the address is extracted from the database storage unit 107 of FIG. 3 and displayed on the display unit 109. After the display, the display is not the graphic data desired by the operator, and the input unit 101 does not give a stop instruction. Then, the data designation unit 104 determines that there is no stop instruction. Subsequently, the reference table of FIG. 5 is searched by the subsequent address determination unit and it is determined that there is subsequent data. Then, the address "3" of the second stored identifier of the search target type identifiers is extracted from the reference table of FIG. And
Similarly to the above, the graphic data of the address is extracted from the database storage unit 107 of FIG. 3 and displayed on the display unit 109. After this display, the operator gives a stop instruction from the input unit 101, assuming that the figure data is desired. Then, the data designating unit 104 determines that there is a stop instruction, and shifts to the candidate page turning process.

In the candidate turning process, the data designating unit 104 causes the page (candidate page) having the data as a constituent element of the currently displayed search target type data, in other words, the data desired by the operator to be the table of contents. It is read from the reference table of the data storage unit 108 (S200). Then, the page processing unit 105 reads out the address of the data forming the page from the document table, and then extracts the data of the address from the database storage unit 107 (S201). Then, the content of the page is displayed on the display unit 109 according to the extracted data (S203). After the display, it is determined whether or not a stop instruction is input from the input unit 101 (S206). When it is determined that the stop instruction has not been input, the subsequent page determination unit of the page processing unit 105 determines whether or not there is a candidate page other than the displayed page (S207). If it is determined that
With respect to the candidate pages other than the displayed page, data forming the page is extracted by the same process as described above and displayed on the display unit 109. Thereafter, the above processing is accepted from the input unit 101 as a stop instruction, or
The subsequent page determination unit repeats the above process except that there is no candidate page other than the displayed page, in other words, all candidate pages are already displayed.

Specifically, the address of the data displayed on the display unit 109 when the input unit 101 gives a stop instruction was "3". From the reference table of FIG. 5, the identification numbers "A-2" and "C-2" of the page having the address "4" as a constituent element are read out. Next, from the document table in FIG. 4, first, the identification number "A-2"
The addresses "3", "4", and "5" of the data are read. Then, the database storage unit 10 of FIG.
The data of the addresses “3”, “4”, and “5” are extracted from 7 and displayed on the display unit 109. The page of this identification number "A-2" is displayed in FIG. After this display, the operator does not operate the stop key because the displayed page is not the desired page. Then, it is determined that there is no stop instruction. After that, the subsequent page determination unit determines that there is a candidate page that is not displayed, the above-described processing is performed on the remaining candidate page (recognition number C-2), and the data that forms this candidate page is displayed on the display unit 109. Is displayed. This identification number "C-
2 ”page is displayed. After this display, the operator determines that the page is the desired page and inputs a stop instruction from the input unit 101.

Next, when a stop instruction is input from the input unit 101, the page designating unit 106 stops the above process and displays the page displayed on the display unit 109 when the stop instruction is input. It is left as it is (S208), and this page turning operation is completed. The operator can confirm the desired page on the display unit 109.

On the other hand, when the subsequent page determination unit determines that all the candidate pages have already been displayed, a message indicating “no data to be displayed” is displayed on the display unit 109, and this page is displayed. The turning operation is completed. In addition, in the above-described embodiment, the page turning is performed with one type of search target, but the present invention is not limited to this. It is also possible to provide a designating means for designating two or more types and perform the above-mentioned page turning one by one among the designated types.

[0040]

According to the present invention, in view of the above situation, it is possible to turn a page by displaying only a designated type, that is, a character, a figure, and a photograph. Therefore, even if different types of data exist on one page, The time spent for display can be suppressed. Therefore, high-speed page turning can be performed and a desired page can be quickly searched. Also, since the search is performed with the specified type, pages that do not include that type will not be displayed. That is, since the search can be limited to the type of the desired page, it is not necessary to turn over all the search symmetry.
