Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an electronic dictionary in which, for example, when a predetermined English word is specified using a character key, an English unit synonymous with the English word can be displayed on a display means.

Prior Art Conventionally, this type of electronic dictionary is equipped with a dictionary memory that stores word data for each English word.
As shown in FIG. 1, this dictionary memory includes a word storage section 1 that stores word data of an English word for each address, and at least one word data of an English word synonymous with the English word. A synonym storage unit 2 was provided.

For example, as shown in FIG. 2, if the content of the word storage unit 1 is the word data “CONSIDER”, the corresponding consent storage unit 2 contains data such as “THINK”, “REFLECT”, and “DELIBERATE”.
Multiple pieces of synonymous data such as, etc., were stored.

Therefore, in the dictionary memory, in addition to the word storage section 1, a synonym storage section 2 that stores synonym data having a storage area larger than that of the word storage section 1 is secured at each address. Memory capacity was inevitably increasing.

Therefore, in order to solve the above problem, the present applicant provided a word storage section 3 and an address storage section 4 for each address, as shown in FIG. The address storage unit 4 stores the word storage unit 3 and the address 6 in which the word 5 synonymous with the word 5 is stored, and the address is stored in the address storage unit 4 according to the address 6 stored in the address storage unit 4. The words 5 in the word storage unit 3 of 6 are displayed as synonyms, and the address 6 to be stored in each address storage unit 4 is selected by selecting “CONSIDER” → “THINK” →
"REFLECT" → "DELIBERATE" →
"CONTEMPLATE" → "STUDY" →
The first application was filed for one in which synonyms are selected in a loop and displayed in sequence, such as ``CONSIDER''. This made it possible to save the storage capacity of the dictionary.

However, some English words, such as "THINK" shown in FIG. 4, belong to two synonymous groups. In this case, if the groups were simply connected, there was a risk that completely unrelated words would be connected, so the words were classified in advance so that they belonged to one of the groups. Therefore, when an English word belongs to a plurality of synonymous word groups, there is a problem in that it is not possible to search for an optimal synonymous word from among these synonymous word groups.

Purpose of the Invention The present invention has been made to solve the above-mentioned problems, and its purpose is to save the storage capacity of the dictionary memory, and also to save the storage capacity of the dictionary memory. To provide an electronic dictionary capable of systematically searching for an optimal synonym for an English word from among synonym word groups when there is a word.

Embodiment Hereinafter, an embodiment in which the present invention is embodied in an electronic typewriter equipped with an electronic dictionary will be described with reference to the drawings.

In FIG. 5, an electronic typewriter 11 equipped with an electronic dictionary is provided with various keys such as a shift key 13, a character key 14, and a space key 15 as input devices on its input board 12.

Various character data such as alphanumeric characters and numbers are selected and input.

On the left side of the shift key 13 are provided a synonym call key (hereinafter referred to as a call key) 16 as a synonym call means and a clear key 17. Used when you want to know English words,
The clear key 17 is used when it is desired to specify a new English word.

Further, above the clear key 17, a group designation key 18 is provided as a selection means, and is used to select a desired synonymous word group from a plurality of synonymous word groups. A display device D as a display means is provided at the rear center position of the input board 12, and displays information such as the English word 19 input using the character keys 14 shown in FIG. Group number 2 as group data indicating groups of synonymous words by loop
1 is now displayed.

A printer device 22 is provided on the rear side of the input board 12, and each time the space key 15 is pressed, characters are printed on a printing paper P based on character data inputted using the character key 14.

Next, an electric circuit built into the electronic typewriter 11 configured as described above will be explained.

In FIG. 7, a central processing unit (hereinafter referred to as
(referred to as CPU) 23 is an input board 12 with character keys 14, call keys 16, group designation keys 18, etc.
On-signals based on the on-operation of various keys provided above are input, characters are displayed on the display D based on these input signals, and characters are printed on the printing paper P via the printer device 22. There is.

A read-only memory (hereinafter referred to as dictionary memory) 24 as a storage device stores word data of a large number of English words 19 and synonyms 2 of the English words 19.
It stores synonymous address data for indicating 0, and as shown in FIG. 8, each address is composed of a word storage section 24a and an address storage section 24b.

Then, 1 is stored in the word storage section 24a of each address.
Word data for 19 English words is memorized,
As shown in FIG. 9, the word data of the English words 19 are stored in alphabetical order from the word storage section 24a at the first address to the word storage section 24a at the last address.

On the other hand, each address storage unit 24b specifies the address of the word storage unit 24a where English word data having a synonym 20 relationship with the English word 19 in the word data stored in the word storage unit 24a at that address is stored. Synonymous address data for and group data in which mutually related synonymous words are grouped are stored. In this embodiment, in order to secure a plurality of synonyms for this "CONSIDER", the address 100 is set as shown in FIG.
has synonymous address data for address 1000, address 1000 has synonymous address data for address 500, address 500 has synonymous address data for address 200, and address 200 has synonymous address data for address 200.
00 stores synonymous address data of address 150, address 150 stores synonymous address data of address 700, address 700 stores synonymous address data of address 100, and in addition to these data, "*1" is stored. ” is stored, which distinguishes it from other synonymous word groups.

In addition, as shown in Figure 9, in the case of a synonymous word group of "ASSUME", synonymous address data is stored in each address in the same way, and other synonymous words "*2" are stored in addition to these data. It stores group data that distinguishes it from word groups.

In other words, in this case, for the English word "CONSIDER", "THINK", "REFLECT",
"DELIBERATE", "CONTENPLATE",
"STUDY" and "REFLECT" are grouped as synonyms, and "BELIEVE", "THINK" and "SUPPOSE" are grouped as synonyms for the English word "ASSUME". .

Moreover, in this case, the English word "THINK" belongs to both synonymous word groups and its address storage unit 24
Both address data are stored in b, but both address data are "*1",
They are distinguished by group data called "Address*2".

The working RAM 25 is a random access memory, and stores character data input using the character keys 14, word data and synonym address data read from the dictionary memory 24 by the CPU 23.

Next, the operation of the electronic typewriter constructed as described above will be explained with reference to the flowchart of the CPU 23 shown in FIG.

Now, while the CPU 23 is waiting for ON signals from various keys on the input board 12, the user first presses the letter "T" to display the synonym 20 of the English word 19 "THINK" on the display D. Turn on 14 (step 1). Then,
The CPU 23 stores the character data of “T” in the working RAM 2.
5 (step 2) and the same RAM.
Display D based on the character data stored in 25.
A display control signal is output to display the character "T" (step 3).

Next, the CPU 23 waits for operation of the call key 16, clear key 17, space key 15, or character key 14 (steps 4 to 7). Next, when the user turns on the "H" character key 14, the CPU 23
similarly stores the character data of "H" in the working RM25, and outputs a display control signal to the display D based on the character data to display the character "H" next to the previously displayed "T". Display.

Thereafter, by sequentially operating the character keys 14 of "I", "N", and "K", "T", "H", "I", "N", and "K" are stored in the work RAM 25. " are stored, and the English word 19 "THINK" is displayed on the display D.

In addition, if you want to change the input English word 19 while operating the character keys 14 or after selecting the English word 19 "THINK", or if you make a mistake in spelling and want to start over, turn on the clear key 17. If you do so, the CPU 23 responds to the ON signal of the clear key 17 and clears the working RAM 2.
5 and clears the display on the display D, and waits for the character key 14 to be operated again (step 8).

Also, if you want to print each character that you have input using the character key 14 on the printing paper P, press the space key 15.
Just turn it on. In response to the on operation of this space key 15, the CPU 23 controls the working RAM 25.
A print control signal is output to the printer device 22 based on the character data of , and the English word "THINK" 19 is output.
After printing (step 9), work RAM 2
The contents of 5 are cleared and the display on display D is also cleared to end the process (step 10), and the process waits for new key operations.

Next, when the call key 16 is turned on to search for the synonym 20 of the selected "THINK", the CPU 2
3, in response to the ON signal of the call key 16, the dictionary memory 2 stores the same English word as the English word consisting of the five character data stored in the working RAM 25.
A processing operation for searching from the word data stored in the word storage section 24a of each address of 4 is executed (step 11).

At this time, when the CPU 23 searches for the word data of the English word "THINK" from the dictionary memory 24 (step 12), the CPU 23 stores the searched word data in the word storage section 24a and the corresponding address storage section 24b. Read out the stored group data and address data (Step 1)
3) The data is transferred to the working RAM 25 (switch 14).

At this time, the CPU 23 first reads out the group data of "*1" and the address data (500) corresponding to the same data.

On the other hand, if the English word "THINK" 19 is not stored in the dictionary memory 24,
CPU23 immediately displays English word 1 corresponding to display D.
After displaying a message indicating that there is no 9 (step 15), the system waits for a new key operation.

Based on the read data "*1", the CPU 23 displays the group number 21 "1" on the display D to indicate that it is a synonym word group of "THINK", and also displays the content of the synonym address data read as well. In other words, in the case of this embodiment, the address is 5 based on the content that the address is 500.
"REFLECT" stored in the storage unit 24a of 00
Word data and address storage unit 24 for English words
Address data stored in b (address 20
0) is stored in the read work RAM 25.
Based on the word data stored in the working RAM 25, the CPU 23 displays the English word 19 of the word data as a synonym 20 on the right side of the English word 19 previously displayed on the display D (step 16).

Therefore, the user can know the synonym 20 "REFLECT" which belongs to the synonym word group "THINK" in the selected English word 19 from the display on the display D.

When the synonym 20 "REFLECT" is displayed, the CPU 23 waits for the call key 16, clear key 17, space key 15, and group instruction key 18 to be turned on (steps 17-20).

Next, when the user turns on the call key 16 again in order to know the synonym 20 other than "REFLECT" in this synonym word group, the CPU 23 responds to this by first selecting the synonym 20 displayed on the display D. 20
After deleting only the working RAM (step 21),
Based on the address 200 previously stored in the RAM 25, the word data ``DELIBERATE'', the group router ``*1'', and the address data 150 of the start address stored in the address 200 are read out and stored in the RAM 25. (Steps 22-23).

Based on the word data and group data stored in the working RAM 25, the CPU 23 displays the English word 19 of the word data as a synonym 20 on the right side of the English word 19 previously displayed on the display D, and also The number 21 is displayed (step 24).

Thereafter, each time the user turns on the call key 16, each data stored in the previously read address storage section 24b is read out and the "THINK" button is pressed.
"REFLECT" → "DERIBERATE" →
"CONTENPLATE" → "STUDY" →
The CPU 23 sequentially displays the English words "CONSIDER" → "THINK" on the display D as synonyms 20. In this case, after "THINK", which is the same as the English word 19 selected to find the synonym 20, is displayed, if the call key 16 is further turned on in the same order as above, the above-mentioned agreement will be displayed again in the same order as above. The display of word 20 is repeated.

Next, if you want to know other synonymous word groups to which "THINK" belongs, you can operate the group designation key 18. At this time, the CPU 23 checks whether there is other group data in the address storage section 24b at the address where "THINK" is stored (step 25), and reads out the group data "*2" and the address data "800". (Steps 26 to 2)
7).

Then, similarly to the above, the synonym 20 "SUPPOSE" and the group number 21 "*2" are displayed on the display D (step 28). After that, if you operate call-16 in the same way, "THINK", "SUPPOSE", "ASSUME" will be displayed as above.
The synonym "BELIEVE" will be displayed one after another.

Therefore, the user can access the dictionary memory 24 simply by operating the call key 16 and the group designation key 18.
It is possible to systematize and sequentially know two synonymous word groups stored in . Moreover, the dictionary memory 24
For each address, in addition to the word storage section 24a that stores word data, only the address storage section 24b that stores address data indicating the address of the word data where the synonym 20 of the word data is stored is secured. Compared to storing synonymous word data in each address, the storage capacity of the dictionary memory 24 is much smaller.

Next, when the user selects, for example, "STUDY" as a synonym 20 of "THINK" and turns on the space key 15 to print this on the printing paper P (step 18), the CPU 23 responds to this. After outputting a print control signal to the printer device 22 to print the English word "STUDY" on the paper P (step 29), the contents of the working RAM 25 are cleared and the process ends (step 30), and various key operations are performed again. will have to wait.

Furthermore, if the user wishes to select a new English word from the beginning without printing it, he or she may operate the clear key 17. In this case, in response to the on signal of the clear key 17 (step 19),
After clearing the contents of the working RAM 25 and the display on the display D, the CPU 23 waits for the next key operation (step 31).

Note that the present invention is not limited to the above-mentioned embodiment, and may be implemented by adding third and fourth synonymous word groups to one English word, for example. In this case, the number of group routers will also increase accordingly. In this case, each time the group designation key 18 is turned on, the next group data will be read out in sequence.

Effects of the Invention As detailed above, according to the present invention, the storage capacity of the dictionary memory can be saved, and when there are words that belong to multiple synonymous word groups,
This method has an excellent effect of being able to systematically search for an optimal synonym for this word from among these groups of synonymous words.
