DETAILED DESCRIPTION OF THE INVENTION The present invention provides an information retrieval device such as an electronic dictionary, an electronic translator, or an electronic encyclopedia, in other words, if a headword is designated and a predetermined instruction is given, it will correspond to one designated headword. Contents (
This device relates to an information retrieval device that outputs translations, translations, etc., and is particularly designed to reduce the number of keys.By operating a character search key, characters are displayed one after another, and the desired character is displayed. By operating the character input/headword sequential search key at the time when is displayed, character input is performed and the search for a headword starting with the input character is started. The present invention provides an information retrieval device characterized in that, after the input/headword forward search key is operated, the character search key functions as a headword reverse key.

Hereinafter, the present invention will be described in detail based on Examples.

FIG. 1 is a plan view showing the appearance of an electronic English-Japanese/Japanese-English dictionary with a computer function, which is an embodiment of the present invention.

In the figure, 1 is the mode selection switch; power off,

Reference numeral 2 is a character search key, and when this key is operated in the English-Japanese mode, the alphabets are sequentially displayed in alphabetical order. Also, in Japanese-English mode, if you operate this key, katakana characters will be displayed sequentially in the order of ai and ueo. 3 is a character input/headword order search key, which is used in English-Japanese mode (
In Japanese/English mode), after specifying the desired alphabet (Katakana) by operating the L character forward search key 2 or the character backward search key (described later), operate this key to select the first character specified. After inputting, English words (Japanese) starting with the corresponding Kuga character are sorted alphabetically (5
They are sequentially read out from memory and displayed in the order of the zero syllables.

4 is a character that functions as a backward search key for characters until the manual text input/headword forward search key 3 is operated, and after the above key 3 is operated, a character that functions as a reverse headword search key. It is a backward search key that also serves as a headword backward search key. 5 is a translation instruction key, and the above-mentioned headword forward search key 8 or headword backward search piece-4
If you call up the desired English word (Japanese) by operating this key and then operate this key, the Japanese (English word) corresponding to the above English word (Japanese) will be displayed. 6 is a display section, and 7.8 is a character index printed in advance around the display section 6.5. This character index is displayed when searching for characters or as a headword, and when the user writes J1. This is provided so that the progress of the search operation can be grasped intuitively.

Note that keys other than the above-mentioned keys are keys used in the computer mode.

FIGS. 2 and 8 are diagrams for explaining the search operation progress display using the E character index.

FIG. 2 (11) is a diagram showing the dots used to display the progress of the search operation in the English-Japanese mode, and among the dots on the upper and lower sides of the lower seven digits, the dots at the positions shown in the diagram are used.

Figure 2 (2) shows the display when searching for characters, character + l d
11 is specified, and as shown in the figure, the specified character "d" is displayed in the most significant digit, and the specified character is displayed from the character index of "aa". The progress status of the character search operation is displayed in analog form by lighting up all the dots corresponding to each character index up to the character index "d".

Note that the progress status of the character search operation may be displayed by lighting up only the dots corresponding to the character index of the specified character1, or the number of dots corresponding to each character index may be It is also possible to have a configuration in which there are multiple numbers instead of one.

Figure 2 (3) shows the display when searching for a headword as “desk”.
This example shows the case where the word "desk" is specified, and as shown in the figure, the top two characters of the currently specified word "desk" are displayed in the top two digits. At the same time, the specified word “d” is obtained from the character index of “eIa”.
The progress of the headword search operation is displayed in an analog manner by lighting up all the dots corresponding to the character index of the second character "e" in "esk".

In this case as well, the progress of the headword search operation may be displayed by lighting only the dot corresponding to the character index of the second character of the currently specified headword.

FIG. 3F, 1) is a diagram showing the dots used to display the progress of the search operation in the Japanese-English mode, and the dots on the upper and lower sides of the lower five digits are used. Figure 3 (2
) shows the display when searching for a character, taking as an example the case where the character "tsu" is specified, and Figure 3 (
3) shows the display when searching for a headword, taking as an example the case where the word "love do kei" is specified. As shown in FIG. 8(3), in the Japanese-English mode, the upper four digits are used to display headwords.

FIG. 4 shows specific key operations and displays in the English-Japanese mode, taking as an example the case of translating the word "boat" into Japanese.

First, press the character forward search key (-).

As a result, Q all is displayed in the most significant digit of the display, and the dot corresponding to the character 68'' lights up.If you press the forward search key successively, the displayed character becomes 'b''. At the same time, the dot corresponding to the character index "b" lights up anew.

Here, by pressing the character input/headword order search key (↓), a search for headwords starting with "b" will be started. In other words, while the L key is pressed, headwords starting with "etb" will be searched in alphabetical order. are read out in sequence,
The top two characters are displayed, and the above-mentioned search operation progress status display is also performed.

Release the headword order search key when the top two letters of the target word 'boat' are displayed.This will display all spellings of the headword being read at that time. 1, "body" is displayed in the figure.

Since I had gone too far through the target word "boat," I pressed the reverse word search key (4). Each time this key is pressed, the previous entry word is displayed (full spelling display). In this case, the entry word immediately before "body" is "boat," so the desired word "boat" is displayed with one key operation.

The headword to be used as K-hayashi is displayed, and translation instructions are given.

If the displayed entry word is a entry word before the target entry word when the entry word order search key is released, the entry word order search key is subsequently pressed. Each time you press the headword order search key, the next headword will be displayed in sequence (full spelling display), so keep pressing this key until the desired word is displayed, and the desired headword will be displayed. Press the translation instruction key at that point.

FIG. 5 is a block diagram showing the schematic configuration of this embodiment.

In the figure, 11 is a microprocessor, 112 is a key input device, and 13 is a memory (ROM) for storing dictionary information.
, 14 is a display control section, 6 is a display section, 15 is an address bus, and +6 is a data bus. , microprocessor-1
1 outputs a key strobe signal KS to the key manpower device 12, performs a key power input, and reads the contents. The display control unit 14 is a type of memory that stores lighting and non-lighting in correspondence with each dot on the display unit 6, and is controlled by the microprocessor 1.
1 causes a desired display to be performed by writing information corresponding to a display pattern into the display control section 14.

The microprocessor 1l includes a ROM 17.0 that stores a control program. RAM18 used as registers and flags. An arithmetic control section 19, an input/output buffer (not shown), and an internal bus (not shown) that communicates these are provided.

FIG. 6 is a diagram showing part of the contents stored in the memory 13.

In the figure, WA is a word information storage area, in which English words are sequentially stored in alphabetical order, and immediately after each English word, a Japanese word having the same meaning as the English word is stored. SAH This is a storage area for storing the above-mentioned word information, and specifically, the addresses (AD,) of each Japanese word in I- are sequentially stored in the order in which the Japanese words are arranged in alphabetical order.

EA is an English word start address table storage area that sequentially stores the addresses (ST, AD,) of the first English word starting with each letter from a'' to 6z'', and J
A is the address (ST,
This is a Japanese start address table storage area that sequentially stores AD, ).

FIG. 7 is a flowchart showing the control procedure of the microprocessor, but only the portions related to the present invention are shown.

In the figure, the flag indicating that the FIH character forward search key (-) or character backward search key (4) has already been pressed, F2 is the press of the character input/headword forward search key (↓) F3 is a flag indicating that the character input/headword forwarding search key has been pressed, SC is a character code buffer, B is a buffer, and C is a counter.

In addition, in this example, the correspondence between characters and character codes is as follows.
[a←01. b←02, ・=-, z←26], Wa ``A++27.i←28......, 4e7QJ.

After the power is turned on, initialization (clearing each buffer, resetting each flag, etc.) is performed, and the state of the mode switch is read. If not in calculator mode, proceed to dictionary routine.

When the character forward search key is pressed, flag F1 is set, and then the character code (a) for 6a'' is displayed in English-Japanese mode, and the character code (7) for 'a' in Japanese-English mode. , are respectively input to the character code buffer SC, and character display and character search operation progress status display based on the contents of the SC are performed [FIG. 4 (1)]. When the forward search key is pressed for the second time or later, the contents of the character code buffer SC are counted up, and the character display and character search operation progress status display based on the contents of the SC are performed in the same manner as above. (Fig. 4 +21'), the contents of the character code buffer SC are changed to the character code (2) of "'2" or "wa" by counting up the E record.
character code (if it is larger than wa, change it to a”
The character code (a) of ``A'' or the character code (7) of ``AJ'' is input to sc. .

When the backward character search key is operated, the character search is performed in the reverse order of the character forward search key.

Character forward search key If you press the character input/headword forward search key when you call up the desired character by operating the backward search key, flag F3 will be set, and then character input will be performed (character The character code stored in code buffer SC is input to buffer B)
, the first English word starting with the input character "!take" is searched for Japanese.Then, the E-position 2 characters of the searched word (
(in the case of English words) or 2 to 4 characters (in the case of Japanese), and the above-mentioned headword search operation progress status display is performed.

Continuing to press the above character input/headword order search key, when the content of counter C becomes equal to the set value Cm, flag F2 is set, and then the next English word in alphabetical order or the next Japanese word in alphabetical order is read out, and the top two characters or two to four characters are displayed together with the headword search operation progress status display.

From then on, while the above keys are being pressed, the Japanese words for the fourth English word are read out in alphabetical order or 1j50 order, and the display of the top 2 or 2 to 4 characters indicates the progress of the headword search operation. This is done along with the status display.

When the predetermined spelling is displayed, if you release the press of the character input/headword order search key, flag F2 is reset and counter C is cleared, and then the headword being read at that time is displayed. Full spelling is displayed.

If the search operation has progressed too far, then operate the headword reverse search key (4). Each time this key is pressed, the previous entry word is read out and its full spelling is displayed. In the opposite case, continue to operate the headword order search key. Each time this key is operated, the next headword is read out and its full spelling is displayed. .

If the translation instruction key is operated when the desired headword is displayed, the translated word will be read out and displayed. In the above embodiment, a headword search is performed by specifying one character. However, it goes without saying that the present invention can also be implemented in a system in which a headword search can be performed by specifying two or more characters.

As described in detail below, according to the present invention, it is possible to obtain an extremely useful information retrieval device that can perform a desired retrieval operation with a small number of keys.
