BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information retrieval / display device and its display method, and is particularly suitable for application to an information retrieval / display device and its display method for retrieving information recorded in a disk-shaped storage medium. .

[0003]

2. Description of the Related Art Conventionally, enormous amount of character information and image information included in Japanese dictionaries and English-Japanese dictionaries are stored as digital data in a read-only memory (hereinafter referred to as a CD-ROM) which is an optical disk, and the enormous amount of information is used by a user. There has been proposed a portable search device that searches for information corresponding to the designation of No. 1 in a short time and displays it on a liquid crystal display. In addition, as these retrieval devices, there has been proposed a device in which the pronunciation of a quote or a word displayed on a liquid crystal display can be heard as a voice through a built-in speaker.

[0004]

By the way, in the case of this kind of retrieval device, in order to retrieve information by ideographic characters (that is, the information is retrieved directly from the kanji entered by the user).
Since the memory capacity for storing ideographic character search information is enormous, information is generally searched by phonetic characters. Whenever information is desired to be searched, phonetic characters are searched. The user had to enter the characters to search for. This is a Japanese feature that has the ideographic character "Kanji" and the phonetic character "Hiragana".

Further, even if a plurality of documents are recorded on one CD-ROM, only one document can be searched. At present, when it is desired to search information of another document different from the currently searched document. After finishing the search for the document being searched, another document had to be searched again from the initial state.

[0006] For example, English-Japanese dictionary
I want to look up the definition of the word "patent" when I look up the Japanese translation of "PATENT" using "English-Japanese dictionary" as a search reference. Word
Dictionary Suppose you need to look up a "Japanese dictionary." In this case, after the search by the English-Japanese dictionary is finished and the initial screen is returned to, the word "patent" is searched by using the Japanese dictionary as the search document. After finishing the search, if you want to return to the display state of "PATENT" that was just finished, select the English-Japanese dictionary on the initial screen again and click "PAT"
Since the "ENT" screen has to be called up, there is a problem that it takes a lot of time and labor and a search time is long.

Similarly, even when the same document is the search target, if there is information to be further searched in the information currently being searched, the current search is temporarily terminated, the initial screen is returned, and then another If the user wants to retrieve the information in the above, and want to retrieve the continuation of the information immediately before the end of the retrieval, the original information must be retrieved from the initial screen again.

The present invention has been made in consideration of the above points. The search time required for searching a plurality of documents is significantly reduced, and a plurality of pieces of information of one or a plurality of documents are searched while being compared and referred to at the same time. The present invention intends to propose an information retrieval display device that can be used.

When the CPU 19 inputs an input signal S1 from the keyboard 20, the control signal S is sent to the laser light source drive unit 21, the thread feed motor 22, the biaxial actuator drive circuit 23 and the motor drive circuit 24 of the reproduction block 16.
2 is output to each of them, and each reproduction block 16 is controlled by the control signal S2.

That is, the CPU 19 is a motor drive circuit 24.
To control the spindle motor 25 to rotate at a constant linear velocity (CLV) or a constant angular velocity (CAV),
Further, by controlling the thread feed motor 22, the object lens 26 attached to the biaxial actuator, the photo detector 27, and the pick up 27 composed of an optical element for detecting the focus error are moved to a predetermined track on the data disk 15 (so-called disk). Radial control).

Further, the CPU 19 controls the biaxial actuator driving circuit 23 to move the objective lens 26 of the pick-up 27 up and down to adjust focusing, or to swing the objective lens 26 left and right to irradiate a beam spot to an arbitrary track (so-called). (Tracking control), and the data stored in the data disk 15 is reproduced.

When the error detection / data detection circuit 28 reads the data signal from the data disk 15, the focus detection error or the tracking error is detected by, for example, obtaining the so-called sum or difference. By supplying the focus error and the tracking error to the biaxial actuator drive circuit 23, the objective lens 26 is driven and the focusing and tracking are normally maintained, and the data is accurately read.

Incidentally, the laser beam applied to the data disk 15 is controlled by supplying a detection signal detected from a laser beam output from a laser diode (not shown) to the laser light source drive circuit 21. The power of the laser beam is controlled so that it is always constant during reproduction.

A subcode area and a data area are provided on the disk of the data disk 15 for each frame, for example, and a synchronization signal, position information, time information, etc. are written in the subcode area, and the subcode area is written in the data area. Character information and the like are written.

On the other hand, the reproduced signal including the synchronizing signal and the time information reproduced from the data disk 15 is supplied to the CD (Compact Disc) signal processing circuit 31 of the audio signal processing block 17 through the error detection / data detection circuit 28. It is designed to be done. Here, the CPU 19 is a so-called audio CD in which the data disk 15 attached to the apparatus main body 2 stores audio data, or a so-called CD-R in which character information is recorded such as in a dictionary or encyclopedia.
It is adapted to detect whether it is an OM disk and supply the detection signal to the CD signal processing circuit 31.

At this time, the CD signal processing circuit 31 separates the reproduction signal S3 supplied from the reproduction block 16 into a sub data signal composed of a synchronizing signal and time information and a main data signal, and the main data signal is audio data. In this case, the audio data signal is supplied to the D / A (digital / analog) conversion circuit 32.

In the case of this embodiment, D / A (digital /
The audio data signal supplied to the (analog) conversion circuit 32 is converted into an analog signal by the audio reproduction circuit 33.
And is output as an audio signal S4 via the output terminal 34.

On the other hand, when the main data supplied to the CD signal processing circuit 31 is a charactor data signal or image data, the CD signal processing circuit 31 supplies the charactor data signal to the CD-ROM signal processing circuit 35. It is designed to do.

At this time, the CD-ROM signal processing circuit 35 is a RAM (Random Access Me) which is a memory for temporarily storing the supplied charactor data signal and image data signal.
mory) 36, and is read according to a signal supplied from the CPU 19.

In the case of this embodiment, the data bus 40 has a read only memory (ROM) in which a search program and the like are recorded.
y) 41 and RAM 42 are connected, and the read charactor data signal or the like is transmitted via the data bus 40. For this reason, the ROM 41 has a kana-kanji conversion data area 41A and a main RO as shown in FIG.
It is formed by two regions of the M region 41B.

Here, the data processing system 18 stores the display image in the video RAM 44 when the Kanji character pattern or the like is read from the Kanji character ROM 43 according to the character data signal, and the display image is displayed based on the control signal inputted from the CPU 19. Video RAM 44 under control of controller 45
The display image inside is read out and displayed on the liquid crystal display 5 provided on the lid 3.

Further, the apparatus main body 2 is provided with an interface connector 50. When an external connection terminal is connected to the connector 50, the switch 5 is connected at the same time as the connection.
1 is turned on to reset the CPU 19 so that an instruction input through the interface is processed by the external interface processing circuit 52, and the processed data is displayed on the liquid crystal display 5 through the data bus 40. ing.

(1-3) Retrieval Processing of Multiple Documents and Multiple Items Based on the processing procedure of FIGS. 5 and 6, the CPU 19 retrieves other documents or items while holding the retrieved document or retrieval state currently being retrieved. Run and 2 on the LCD display 5
It is designed to display one search result at the same time.

That is, when the CPU 19 starts the processing from step SP1, it moves to step SP2 to read the document information from the data disk 15 and display it on the screen.
The user is requested to select a document (FIG. 7 (A)). When the user selects one document from the displayed plural documents, the operation of the CPU 19 shifts to the subsequent step SP3,
The document name selected by the user is stored.

Next, the operation of the CPU 19 shifts to step SP4 to enter the search condition input mode (FIG. 7 (B)). When the user inputs the search condition here, the operation of the CPU 19 moves to step SP5 to store the search condition input by the user. By the way, step SP3 and step SP5
The information stored in is stored in the RAM 42.

Next, the CPU 19 executes the search at step SP6, and displays the data searched at step SP7 on the liquid crystal display 5 (FIG. 7C). Then CPU1
9 monitors in step SP8 whether or not a further search request is input from the user, and if the request is input, in step SP9, a search request for the same document is received.
Alternatively, it is determined whether the search request is another document.

In the case of a search request in another document, the CPU
The operation of 19 shifts to the step SP10 to generate the window W, displays the document information in the generated window as shown in the next step SP11, and at the same time requests the user to select the document (FIG. 7 (E)). . When the user selects a document, the operation of the CPU 19 moves to step SP12 this time, and the input of search conditions is requested (FIG. 7 (F)).

When the user inputs the search condition here, C
The PU 19 executes the search at step SP13 and displays the searched data in the window W at step SP14 (FIG. 7 (G)). Next, the operation of the CPU 19 shifts to step SP8 in this state and monitors whether or not a further search request is input by the user.

If the user inputs that the search is not necessary, the operation of the CPU 19 is step SP15.
Then, it is determined whether or not the liquid crystal display 5 has the window W. At this time, if it is determined that the window W does not exist, the CPU 19 returns to step SP2 and enters the document selection mode in which the document information is displayed again (FIG. 7A).

On the other hand, if it is determined that there is the window W, the CPU 19 proceeds to step SP16 and reads the data stored in the RAM 42 at steps SP3 and SP5. The state of the CPU 19 is controlled according to the read data. After this, the CPU 19 proceeds to step S
Moving to P17, the window W is closed to return to the state in which the retrieved data is displayed (FIG. 7 (C)).

Of course, when a further search request is made in step SP8, the CPU 19 checks whether it is a search request of another document or a search request of another document, as in the above case, and the user When the user requests a search for another document, the process moves to step SP10 again and creates a new window W on the previously created window.

If there is a search request for the same document at step SP9, the CPU 19 waits for the user's request as to whether or not to retrieve the search condition from the data displayed next. If the search condition is not extracted from the data displayed here, the operation of the CPU 19 is step S.
After moving to P19 and generating the window W, step S
The process returns to P12 and waits for the user to input search conditions.

On the other hand, if the search condition is to be retrieved from the displayed data, the operation of the CPU 19 moves to step SP20 and waits for the user to specify the search condition from the currently displayed data. This operation is performed, for example, by designating the start position and the stop position of the search character using the cursor movement key 8.

In this case, for example, the search character designated by the cursor is underlined. Thus, when the search condition is input, the CPU 19 causes the window W to be generated in step SP21 and moves to step SP22 to determine whether the input search character is an ideographic character (in this case, "Kanji").

If it is an ideographic character, it is converted into a phonetic character (in this case, "hiragana") at step SP23. Of course,
If it is a phonetic character in step SP22, step S
P23 jumps over to the next step SP24 (FIG. 8).
(A)).

If it is necessary to correct the search character here, after correcting the kana character in step SP25,
If it is not necessary to correct the search character, the process directly goes to step SP26 to search for information that meets the search condition. Next, the operation of the CPU 19 shifts to step SP27 to close the window W once, and then opens a new data display window W at step SP28 (FIG. 8 (B)).

Thereafter, the operation of the CPU 19 shifts to step SP8 again to wait for a command from the user. Also C
When there is a request from the user to input a new search condition at step SP18, the PU 19 causes the step SP19 to generate a window W having the same size as the liquid crystal display 5, and then the step SP1.
The process shifts to 2 and waits for the user's key input (FIG. 7 (D)).

The subsequent operation of the CPU 19 is a repetition of the above operation. In this way, the CPU 19 causes the step S
Since the search data made in P3 and step SP5 are stored, the second search result is displayed while the first search result is displayed.
You can search for. Further, in this case, when the second search is completed, the display state of the first search result can be automatically returned.

(2) Operation and effects of the embodiment With the above configuration, a data disk 15 storing four documents, for example, an English-Japanese dictionary, a Japanese-English dictionary, a Japanese dictionary, and a Hanwa dictionary, is attached to the cartridge storage holder 12, and the fan When the first information retrieval mode is entered by pressing the cushion key 10, the document selection screen is displayed and the document names are listed as shown in FIG. 7 (A).

When the user selects the English-Japanese dictionary here, the screen moves to the word input screen as shown in FIG.
When the search of "NT" is designated, the searched contents are displayed on the screen as shown in FIG. 7C (step SP1 to step SP7).

In this state, if it is desired to retrieve the meaning of "patent" in the displayed sentence, it is necessary to return to the initial screen in the past, but in this embodiment step SP7 to step SP8,
In step SP9, it is determined whether to search another document. When another document search is selected by the function key F6, a window is opened in the right half on the display screen as shown in FIG. 7E, and the document selection screen is displayed.

At this time, when the user moves the cursor and selects the Japanese dictionary, the word input screen of the Japanese dictionary is displayed in the window and the state of waiting for the input of the search character is entered. When the user specifies "Totsukiyo" as the search character (Fig. 7 (F)), the search contents of two dictionaries, the English-Japanese dictionary and the Japanese dictionary, are displayed on the screen as shown in Fig. 7 (G). (Step SP14).

At this time, if the search in the Japanese dictionary is completed (that is, if another character string is desired to be searched in the English-Japanese dictionary), the CPU 19 reads the past search process in step SP16, and then, via step SP6. Directly move to the search display screen of the English-Japanese dictionary and continue the search operation.

By thus storing the information necessary for the search by the CD-ROM or the like, it is possible to automatically return to the original search result display state. If the document currently searched is a Japanese dictionary, the CPU 19 proceeds to step SP.
8. In step SP9, it is determined whether the user desires to search for another item in the same document while displaying the contents of the document currently being searched, and if multiple item search is selected by the function key F6, step SP18 Then, the process moves to multiple search on the same document (FIG. 8).

At this time, in step SP20, when the user specifies the search character by underlining the word "application" as the search character, the CPU 19 determines that the specified character is an ideographic character and executes steps SP21 to SP23. Kanji-to-Kana conversion is executed sequentially and "Shiyutsugan" is displayed in the window.

In this case, if the kana conversion is correctly executed, the CPU 19 executes the search at step SP26,
The search result is displayed in the window (FIG. 8 (B)). When the user gives an instruction to close the window (step SP8), the CPU 19 shifts to the search result output screen of the first layer based on the read information on the search process.

According to the above configuration, since multiple documents can be searched, it is possible to use a plurality of documents stored in one CD-ROM as a comprehensive dictionary and share a dictionary in several languages and various databases. It is possible to greatly reduce the search time and realize the search while comparing the recorded data. In addition to enabling multiple searches in the same document, if there is a character sequence to be multiple searched in the display screen in this case, the specified character sequence is converted into phonetic characters to significantly increase the search time. It can be shortened.

(3) Other Embodiments In the above-described embodiment, the data disk 15 is encoded.
grish-Japanese dictionary Although the case where four documents of "English-Japanese dictionary", Japanese-English dictionary, Japanese dictionary and Hanwa dictionary are stored is described, it can be widely applied to the case where documents of other combinations are stored.

Further, in the above-mentioned embodiment, the case where the window is displayed in the right half of the screen at the time of the multiple document search and the multiple item search has been described, but the present invention is not limited to this.
The window may be displayed at another position such as dividing the screen vertically into two, or may be a window W having the same size as the screen.

Further, in the above-mentioned embodiment, the case where only two layers are displayed has been described, but the present invention is not limited to this, and three or more layers may be displayed.

Further, in the above-mentioned embodiment, the case where the multiple document search and the multiple item search are executed according to the flow charts shown in FIGS. 5 and 6 has been described. However, the present invention is not limited to this, and other processing is performed. You may perform a search according to a procedure.

Further, in the above-mentioned embodiment, the case where the search character is underlined is described in the case of the multiple item search, but the present invention is not limited to this, and the search character may be displayed in reverse video or blinking display. It can also be widely applied to, for example.

Further, in the above-mentioned embodiment, a case has been described in which a part of the display data in the search screen is designated as a search word, but the present invention is not limited to this, and key input may be performed. .

[0064]

As described above, according to the present invention, when the first search result is displayed, the first selection information and the first search condition character are stored in the input information storage means. ,
Even if the display of the second search result in which the second selection information and the second search condition character are newly input and displayed by the input unit is ended, the second information stored in the input information storage means is stored. By reading the first selection information and the first search condition character, the first information relating to the first search condition character is again retrieved from the information storage unit based on the document selected by the first selection information. By searching and reading and displaying the first search result on the display unit, it is possible to return to the display state of the first search result when the display of the second search result is completed. Therefore, it is possible to eliminate the conventional operation of ending the current search operation once and then moving on to the next search operation, and it is possible to further reduce the search time required when executing a plurality of searches.
