Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a linguistic information retrieval device that can search for a plurality of languages using a common address, temporarily store the address, and specify the type of language when reading out the information.

Generally, when searching for a large amount of information, the searched information is recorded by writing it down or printing it out. However, taking notes is troublesome, and printing requires a printer, which requires a large device. There is a drawback.

Therefore, the present invention provides an easy-to-use language information retrieval device that temporarily stores retrieved information instead of taking notes and reads it out in a predetermined language when necessary.

FIG. 1 is a block diagram of a linguistic information retrieval device showing one embodiment of the present invention. In the figure, 1 is the keyboard, with alphabet keys from A to Z, English,
It has a language memory designation key for selecting French, German, and Spanish, a search key, a key for temporarily writing searched data into the data memory, a key for reading out the data in reverse, and a clear key. The keyboard 1 has the keys wired in a matrix, receives a key scan signal from an input/output gate circuit 11, and outputs a key signal to the input/output gate circuit 11 when a key is pressed.

Four of the output lines of the input/output gate circuit 11 are also applied to each of the language memories 21-24 in addition to the keyboard 1, and are also used as outputs for designating any one of the language memories 21-24. The diodes D ₁ to _{D 4} prevent the effects of double hitting on the keyboard 1. Each language memory 21-2
4 is the memory corresponding to English, French, German, and Spanish, for example, each of 144K bits.
When configured with CMOS-ROM, it is possible to store 24,576 characters with 6 bits per character. Therefore, if one word is composed of about 10 characters, it is possible to memorize about 2,400 words. The addresses of each memory 21 to 24 are selected by a common address line 25 and output to a data line 26, and the address line 25 receives address signals A ₀ to A ₁₄ from an address register 27.
is supplied.

The output of the address register 27 is sent to the adder 28.
and the address memory 3, and the adder 28
The address is changed and advanced by , and is temporarily stored in the address memory 3. Further, the output of the address register 27 is given to the address memory 3, stored as data, and conversely read out from the address memory 3 to the address register 27 via the adder 28 when necessary.

The address memory 3 is for storing, for example, 10 to 30 pieces of address data. Each data in the address memory 3, which is composed of 15 bits output from the address register 27, is stored in the address counter 3.
0, and reading or writing is performed by a read/write signal R/W from the control circuit 4.

The control circuit 4 constantly reads out and executes the program in the program memory 5, and normally drives the display circuit 63 via a key scan program that detects presses on the keyboard 1, an output gate circuit 61, and a column drive circuit 62. A display program is running. When a key is pressed, a program corresponding to the key is executed, information is searched, and the results are displayed.

The display circuit 63 has display digits for 10 characters, each digit consisting of 5 columns and 7 rows, and has an element for displaying a special symbol below only a specific digit.

Reference numeral 29 is a language selection memory, which is composed of a 2-bit register, and stores which of the four languages has been selected by the language memory designation key in four states from 00 to 11. A selection signal, a so-called chip select signal, is output to the memory selection signal line 12, and the corresponding memory among the language memories 21-24 is selected. For example, language selection memory 2
When 9 is cleared to 00, for example, English memory 21 is mainly selected.

Reference numerals 71 and 72 are first and second registers, which are 10-digit registers with 6 bits per digit.The first register 71 mainly stores codes corresponding to characters input from the keyboard 1, and the second register 72 stores the codes corresponding to the characters successively retrieved from the language memories 21-24. The contents of the first and second registers 71 and 72 are compared by a subtracter 73. When comparing, the first register 71 to the second
The contents of the register 72 are subtracted by a subtracter 73 to make a determination.

In this example, alphabets A to Z are 000001.
It corresponds to 6 binary bits of ~011010, and A<
Since the relationship is B<...<Z, it is possible to search in alphabetical order by subtraction. For example, English
When inputting ABLE to find out other languages that are supported, if the English memory 21 is searched sequentially in the order of A, ABLE, ABOUT, ..., then A<ABLE,
Conversely, since ABLE < ABOUT, it is possible to perform a search by determining the size of the word's character code.

Note that if words are stored in alphabetical order in each of the language memories 21 to 24, correspondence cannot be established between the language memories. For this reason, in each language, an address code in alphabetical order is stored at the same time as the character code of the word, and the next word is retrieved by reading out the address code. For example, after the character code of the word ABLE, the character code of the next word ABOUT is stored together with the address code, so it is possible to search for words in alphabetical order. Therefore each word has 10 characters +
It consists of an address code of 3 characters. Furthermore, words with the same meaning are stored at the same address location in each language memory, so if the English BAG address is 1234, the French word is stored at the same address location.
SAC, TASCHE in German, BOLSA in Spanish
Both are stored at the same address, 1234. Therefore, from any language memory, the contents of another language memory can be instantaneously switched and read by operating the language memory designation key via the memory selection signal line 12. In other words, if each language is configured with a single memory LSI, the character code of the corresponding word can be read out simply by changing the chip select of each LSI. R is a read signal line.

Next, the operation shown in FIG. 1 will be explained using the flowchart shown in FIG.

First, normally the contents of the first register 71 are the contents of the subtracter 7
3 to the control circuit 4 and display circuit 63
will be displayed. Subsequently, a key scan is performed, and a press on the keyboard 1 is detected from the control circuit 4 via the input/output gate circuit 11. If no key is pressed, the above operation is repeated.

If a key is pressed, for example, a letter key (A~
Z), the character code is stored in the first register 71 via the data line 26. Next, if the language selection memory 29 selects English, the second
The contents of the English memory 21 are read into the register 72, and the contents of the first and second registers 71 and 72 are compared by a subtracter 73. As a result of the comparison, if the contents of the second register 72 are smaller than the contents of the first register 71, the address register 27 is subsequently updated by "1" and compared with the next word. However, since the address register 27 and the first and second registers 71 and 72 are cleared in advance before character input, reading to the second register 72 is performed sequentially starting from the smallest address. Further, when the read contents of the second register 72 match the contents of the first register 71, the original display and key scanning operation is restored. If the contents of the second register 72 become large, there is no match, and an error occurs.

It would be better if the search time is shortened by comparing the character codes input for each character, but in that case, the contents of the first register 71 and the second register 72 do not match, and the contents of the second register 72 are The read character code will be larger. Therefore, if the second register 72 is larger, the contents of the address register 27 may be set to "-1" to return to the original display and key scan operation, and the next character can be input.

Address register 2 in case of search key press
7 is updated sequentially, and the contents of the English memory 21 in the next alphabetical order are read out to the first register 71 and displayed. If you want to read and search, you need to press the search key again, but if you want to do it automatically, you can use the lock key as the search key, or you can set a flip-flop (not shown) to set the search key. You may continue the search based on the conditions.

When a desired word is set using the character key or search key, the user presses the language memory designation key to select another language memory in order to view other languages corresponding to the desired word. Then, store the contents in the first register 7.
By reading out and displaying the desired language in 1, you can know the desired language individually.

After knowing the word of the desired language, press the clear key to search for the next word and move to the first and second registers 71, 72 and address register 27.
Clear. If you want to know the searched word again, you can search in the same way as above, but it is troublesome to search for the same word again.

For this reason, the searched words are temporarily stored. For this purpose, when the write key is pressed, the address information of the address register 27 is written into the address memory 3. First, the contents of the address memory 3 are read in order to detect whether there is a writeable space in the address memory 3. If there is no content, the content of the address register 27 is written into the address memory 3 space. If there is no space, address counter 3
Update 0 and check if there is space in other memory locations. If there is a space, it is written in the same way as above, otherwise it continues checking for spaces.
If there is no space in the total address memory, it is displayed as overflow and writing is prohibited. Similarly, when searching and writing words in another language, the contents of the address register 27 are stored in the address memory 3.
is written to the space location. That is, since the address memory 3 stores the contents of the address register 27 common to each of the language memories 21 to 24, there is no distinction as to which language.

Use the address memory read key to find out what has been written. When the read key is pressed, first, if it is the first read key, the address counter 30 is cleared before reading is performed. That is, reading is performed in the order of writing. During reading, the contents of the address memory 3 are introduced via the adder 28. The adder 28 does not receive the addition signal from the control circuit 4, and the contents of the address memory 3 remain unchanged and the address register 2 is sent to the adder 28.
Transferred to 7. At this time, language memory 21-24
Since the language selection memory 29 for selecting the language does not change,
Words are displayed in the same language. Therefore, by specifying the language memory using the language memory specification key before reading, it is possible to read the contents written in the desired language.

To continue reading, press the read key to update the address counter 30 and read. A lock key may be used for continuous reading, or a flip-flop may be used to store the pressed state.

Since the address memory 3 is usually composed of a semiconductor memory RAM, its contents disappear when the power is turned off, but it is necessary to back it up with a battery or to construct it with a non-volatile memory if necessary.

Furthermore, in the above example, language memories 21 to 24 are used, but by making the language memories 21 to 24 removable, they can be used in the same way for other languages as well. By reading the address, you can know the characters of the corresponding language.

As described above, the present invention temporarily stores the contents of the address register in the address memory, reads it out to the address register when necessary, and reads out the address data from the language memory selected by the language memory designation key into the address register. It is possible to read language information based on the language memory, and by arbitrarily selecting the language memory you wish to read using the language memory specification key,
It is extremely convenient because it can be read in any language, and can also be used for learning purposes.
