A position information storage means for storing the position information in a predetermined order is provided separately, and based on the sequential readout number of the position information from the position information storage means, the above-mentioned position information is stored in a predetermined order different from the storage order in the storage means. The first type information (or the second type information) can be sequentially read from the storage means, and the first type information (or the second type information) can be sequentially read from the storage means in a plurality of orders. The present invention provides an information retrieval device characterized by being able to perform the following functions.

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 which is an embodiment of the present invention.

In the figure, 1 is the display, 2 is the mode switch that also serves as a power switch, 3 is the character input key - 14, 5 is the shift key, 6 is the forward search key, 7 is the reverse search key, and 8 is the translation key. This is the key.

When the mode changeover switch 2 is set to the "English-Japanese" position, the power is turned on and the mode is set to English-Japanese mode. Also, if you set it to the "Japanese-English" position, it will be in Japanese-English mode. Entering text in English-Japanese mode
If you operate 3, the alphabet written on that key,
The cut is entered. - On the other hand, in the Japanese-English mode, if you operate the shift key 4 and then the character input key 3, the kana written on the upper right will be changed to the character input key 3 after operating the shift key 5. If you operate , the kana, voiced mark, or handakuten mark written in the upper left corner will be input.

In the English-Japanese mode, if you input one or several alphabetic characters and operate the forward search key 6 or backward search key 7, the first English word (in alphabetical order) starting with the input character or character string will be found. It is displayed on the display section l. After that, each time you operate the forward search key 6,
The next English word in the alphabet is displayed in order.

Also, each time you operate the backward search key 7,
The previous English word is displayed in order. on the other hand,
In Japanese-English mode, enter one or two kana characters and select the forward search key 6 or reverse search key 50.
The first Japanese word is displayed in phonetic order.

Thereafter, each time the forward search key 6 is operated, the next Japanese word is sequentially displayed in alphabetical order. Furthermore, each time the reverse search key 7 is operated, the previous Japanese language is displayed in order in the alphabetical order.

In the English-Japanese mode, after inputting a desired English word by operating the character input key 3 or calling up the desired English word by operating the search key 6.7, if the translation key 8 is operated, The Japanese translation will be displayed. The same applies to Japanese-English mode. In addition, in cases other than the case where the desired Japanese is input by operating the character input topsoil-3 and the translation key 8 is operated in the Japanese-English mode, if the forward search key 6 is operated after that, , when in English-Japanese mode, the next English word in alphabetical order is displayed, and when in Japanese-English mode, the next Japanese word in alphabetical order is displayed. The same applies to the reverse search key 7.

FIG. 2 is a block diagram showing a schematic configuration of the same embodiment.

In the figure, 11 is a microprocessor, 12 is a key input device, and 13 is a memory (ROM) for storing dictionary information.
, 14 is a display control section, and l is a display section. Further, 15 is an address bus, and 16 is a data bus.

The microprocessor 11 outputs a key strobe signal KS to the key input device 12, and determines the operated key by reading the key input signal Kl. It also specifies the address of the memory 13 and reads its contents.

The display control unit 14 is a type of memory that stores lighting and non-lighting for each segment of the display unit I, and the microprocessor 71.1 sends predetermined display information corresponding to the display pattern to the display control unit I4. A desired display is performed by writing.

FIG. 3 is a diagram showing information stored in the memory 13.

The ED area in the figure contains English word data, and the JD area,
Japanese data is stored in each. FIG. 4 is a diagram showing a part of the specific contents. Corresponding English words and Japanese words are stored in the same order in their respective areas, and each English word (Japanese word) has a 1, 2, 8 degree... The words are numbered. One or more bytes are allocated to store each English word (Japanese), and the delimiter is the most significant bit of the byte that stores the first character (symbol) of each English word (Japanese). is set to "1", and the most significant bits of the other bytes are set to "0". “$” is a code indicating that the spelling is the same as the English word before it.

Note that the fifth method can also be adopted as a method for memorizing English words and Japanese words.

In this embodiment, since the English words are arranged in alphabetical order, the arrangement of the Japanese words is completely irregular. Therefore, as it is, it is not possible to read out Japanese in alphabetical order.

In order to solve this problem, in this embodiment:

First, the block number, which is information stored in the area JT, will be explained.

FIG. 6 shows in more detail the contents of the Japanese language data stored in area JD. As shown in Figure 1, Japanese is divided into plotters for 32 words in the order in which they are stored.
The block number of each block is sequentially 0, 1-, 2,
..., + 11+14+1>...

Figure 7 shows the information stored in area JT.
.

It is a diagram.

As shown in the figure, the block numbers are sequentially stored in the area JT in the order in which the Japanese words stored in the area JD are arranged in alphabetical order. Where the first letter changes, the top two characters are 1. A first delimiter code whose bit is "11" is inserted, and a second delimiter code whose upper two bits are "10" is inserted where the second character changes. Note that the block number is represented by 7 bits, and the most significant bit of the block number storage byte is "0".
is memorized. The lower 6 bits of each delimiter code above are character codes representing the second Japanese character whose block number is stored after the delimiter code (however, the block number stored after the delimiter code is If the word is a memorized Japanese character word, the lower 6 bits are a blank code).

50 Japanese based on the information stored in the area JT
It will become clear from the explanation of the flowcharts that will be described later when read in order according to the phonetic order.

The explanation of FIG. 3 will be continued again.

In the area of EA shown in the figure, the addresses of the first bytes of each division into which the English words stored in the area EDiζ are divided into 64 words in the order in which they are stored are sequentially stored. Similarly, in the JA area, the address of the first byte of each division into which the Japanese language stored in the area JD is divided into 64 words in the order in which they are stored is sequentially stored. The area ES also contains the total number of English words whose first character is "all," the total number of words whose first character is "'a" or "b'', and the first character "1aI+.

The total number of words that are letters from 11 to 11,...
The total number of words whose first character is a letter from "all" to "y" is sequentially stored.Furthermore, in the area JS',
Addresses Pl, +P2, P8 shown in FIG. 7 above
are stored sequentially.

FIG. 8 is a flowchart for explaining the operation of this embodiment.

If you set the mode selector switch to the "English-Japanese" or "Japanese-English" position, the power will be turned on (no) and the mode will be read by pressing nl.

First, the case of English-Japanese mode will be explained. 1 When the character input keys (characters) are operated in the English-Japanese mode, alphabets are input in sequence, and the input alphabets are displayed on the display (n2-na-n4→n5=r+
9).

After entering one or several alphabetic characters, the words of the forward search key (-) or backward search key are searched and the searched words are displayed (n2o(n2
g) -n2+ (n24) -n26-n27- This will be explained in detail below.

Detects the first character of the input character or input character string, and searches for the first character in the corresponding area in the area ES mentioned above.
The total number of words in which is up to the character before the first character of the large blade is read out. Next, calculate in which category of the above 64 word categories a word whose word number is the value obtained by adding "1" to this number is included, and use the area EA mentioned above to calculate the first byte of that category. Read the address of. Later,
The words stored after this address are read one by one, and a match or mismatch with the input character CD is detected.

At this time, if the word read from the memory contains the above input character example, it is considered a match. At this time, the word numbers are also counted at the same time. If a match is found, display that word.

From now on, if you operate the forward search key, the next word will be read out and displayed in sequence (n2o-n2+-n22-
nz6→r+27-+-ngo-na+ -na-)o
Also, if you operate the backward search key, the previous word will be read out and displayed in sequence (n28-"12"'4
= n+25-n2s-n2r-nao-na2).

Once the desired English word is read and displayed, press the translation key (
(translation). As a result, the translated word (Japanese with the same word number as the English word above) is read and displayed (n14-n15-”n+7-” n+
s-” n+9-n 9).Specifically, calculate how many sections of the 64 words the Japanese word number above is included in, and use the area JA mentioned above to find the first byte of that section. Read the address of. Then, search sequentially after that address, read out the Japanese at the time when the word number is the same as the number above, input the spelling of the word you want to display, and then operate the translation key. n14 = n1
5' = n167 n17 = n18 = n+9
-19 to display the translated word. In this case, when searching for Old 6, a match is considered only when the spelling of the word read from the memory completely matches the input character string.

Next, the Japanese-English mode will be explained.

After inputting one or two kana characters, if you operate the forward search key or reverse search key, the first Japanese word starting with the above input character or input character string will be searched in alphabetical order, and the searched Japanese will be searched. The word is displayed [ n2o, (
n2g )−+−n+ (n24) −n2s−” n
ag -” n 34-+ nB5 →nB6-n g
].

First, the first Japanese block number starting with the input character or character string is read from the area JT. This is done as follows. Based on the first character of the input character or character string, the address knob is turned until a predetermined number of the first delimiters -1, -, and - are detected corresponding to the character. At this time, if the above characters are between "A" and "N", the area JT
If the above character is a character between "Yu" and "Ho", then from the address P2 shown in Fig. 7, and if the above character is a character after "Ma". Then, the search is started from the same address P8. This is to shorten the search time, and when only one character is input, the block number stored immediately after the first delimiter code detected last is retrieved. On the other hand, 2
When a character is being input, the character code stored in the lower 6 bits of the first delimiter code is compared with the code of the second input character, and if the two match, the character code stored in the lower 6 bits of the first delimiter code is The block number stored immediately after the first delimiter code is read out, and if there is a mismatch, each time the second delimiter code stored after the first delimiter code is detected, the block number stored in the lower 6 bits is read. The character code is compared with the code of the fourth inputted character, and when the two match, the block number stored immediately after that is read out.

FIG. 9 is a flowchart showing details of n86 in the flowchart of FIG.

When the block number is read, it is then calculated in which section of the sections addressed to the 64 words the block with this number is included, and the address of the first byte of that section is read from area JA (n4o). Thereafter, the search will be started from this address to read the target Japanese and display it, but as a pre-processing, if the above block number is an odd number, the start of the search will be started at the address read from the above JA. 33 counting from the Japanese characters memorized
Address up until the address where the first character of the th Japanese word is stored is specified (n, H-n42)
. If the block number is an even number, the preprocessing is not necessary.

At step 148, the total number of words stored before the block with the read block number (block number next) is input to word number register a, and n44
At ra+]-n45, input the first Japanese word into the visitor A.

Then, proceed as %n46 = n47 → n48, and at 148, the Japanese language stored in register A and register C
determines the relationship with the input character or character string stored in register A, and determines whether they are the same, or the Japanese stored in register A comes after the input character (string) in alphabetical order. If so (when C≦A), go to 115+, otherwise go back to n44, click the word number stored in register a, read the next Japanese word at n45, and do the same as above. make a judgment.

At n51, the word number stored in word number register a is transferred to word number register b, and at n52, the word number stored in word number register a is transferred to r'b+1.
After performing -bJ, the next Japanese word is read into register B at 158. After that, proceed as n54 = n55 = n56, and at 056, the Japanese language stored in register B and the input character string stored in register C
Judge the relationship with □, and if they are the same or the Japanese stored in register B comes after the input character (column) in alphabetical order, proceed to n57, otherwise Then proceed to n62. n62 is 1, determine whether the number of Japanese words read is "32",
N (If o, go back to 152, count up the contents of register b by 1, read out the next Japanese word at 053, and make the same judgment as above.

In n57, the relationship between the Japanese stored in register A and the Japanese stored in register B is determined, and the Japanese stored in register B is stored in register A in alphabetical order.
If the Japanese word comes before the Japanese word in 158, the Japanese word in register B is transferred to register A, and the word number in word number register b is transferred to word number register a, and then it is transferred to n62. Proceed, if not, immediately n62
Proceed to.

163 when the judgment result in n62 becomes Yes.
, transfer the Japanese language in register A to register C, and transfer the word number in word number register a to word number register C.
Transfer to.

Through the above processing, the first Japanese word of the 50-sound rumor blade starting with the input character (sequence) is found in register C, and its word number is found in word number register C.

Thereafter, the process advances to n9 of the flowchart of FIG. 8, and the Japanese language stored in the register C is displayed.

From now on, if you operate the forward search key, n20→n2
+°n22″n26→n88″n87″n88″n86
``n9'' and the next Japanese word will be read out and displayed in alphabetical order.Also, if you operate the reverse search key, n2 will be read out and displayed.
8→n24=n25→n26−n8g−n87”
The sequence advances as nj19→n313-"n9, and the previous Japanese word is read out and displayed in alphabetical order.

When the desired Japanese word is displayed, press the translation key and the corresponding English word will be read and displayed.

It will be done.

In addition, if you input the desired Japanese by operating the character input key and then operate the translation key, n+4-rl15→n+6
→ Town 7 → Town 8 → n9 and the corresponding English word will be displayed. The search in n16 in this case is:

The order stored in the above Japanese data storage area JD,
Read Japanese for one word according to the input spelling, match the input spelling
This is done using a method that detects discrepancies.

In the above embodiment, the program number was stored in the area JT, but instead of the block number, the address itself (such as the address of the byte where the first character of the Japanese character is stored) or the word number. It may also be configured to be memorized. Although such a configuration increases the required memory capacity, the word search routine (n36 in the flowchart of FIG. 8) is significantly simplified and the search time is shortened.

In addition, in the above embodiment, English words are arranged alphabetically and a block number table is provided for searching Japanese words in alphabetical order, but the words are classified into several categories and each category is (The configuration in which the corresponding English words and Japanese words have the same word number is the same as in the above embodiment), a block for searching English words in alphabetical order. A number table and a block number table for searching Japanese words in alphabetical order are provided, and for each category, instructions are given to read out and display English words (Japanese) in the order stored in memory. If the configuration is such that it has a category search key and a spelling search key that instructs to read and display English words (Japanese) in alphabetical order (in alphabetical order), category search, and alphabetical order (in alphabetical order) ) It is possible to obtain an electronic dictionary in which any search can be performed arbitrarily.

As described above in detail, the present invention provides an extremely useful information retrieval device that can sequentially read out type 1 information (or type 2 information) stored in a storage means in a plurality of orders. It is something that can be obtained.
