Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a search method in an electronic dictionary.

In recent years, electronic dictionaries that have the function of translating words from English to Japanese or from Japanese to English have already been put into practical use between languages of multiple countries, for example, English and Japanese. However, the above-mentioned conventional electronic dictionaries are provided with alphanumeric keys and kana keys on the keyboard, and words are specified by operating the keys. When input, the dictionary memory is searched according to the word data, matching data is detected, and the translation process is performed.

However, if a word is specified using alphanumeric keys, kana keys, etc. as in the conventional method described above, the number of keys becomes extremely large, making it difficult to downsize and making the circuit configuration and its control extremely complex. There was a problem.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a search method in an electronic dictionary that allows a desired word to be quickly selected without requiring alphanumeric keys or kana keys.

The details of the present invention will be explained below with reference to an illustrated embodiment having a calculation function and a dictionary function. FIG. 1 is an external front view. In the figure, 1 is the case body,
On one side, that is, the front, a keyboard 3 is provided along with a liquid crystal display section 2 using, for example, a liquid crystal display element. In the liquid crystal display section 2, each digit is, for example, 5.
It has a ×7 dot matrix configuration and has a capacity of 10 digits. Further, the liquid crystal display section 2 is provided with a translation mode display section 2a that shows translation modes from English to Japanese (E→J) and from Japanese to English (J→E). In addition, the keyboard 3 includes a numeric keypad 4 with keys ``0'' to ``9'', a decimal point key, a function key 5 for specifying calculation content or translation processing content, and a setting for switching between translation mode (TR) and calculation mode (CAL). A mode switch 6 is provided. This mode switch 6
doubles as a power switch. The function key 5 can be operated by changing the mode switch 6.
In other words, calculation mode and translation mode have different functions; in calculation mode, the general function of the key name written on the key top, and in translation mode, the key name written corresponding to each key on keyboard 3. It will have the function of In other words, in translation mode, "E←→J", which will be detailed later,
"TR", "IN", "RE", "▼", "▲", "〓", "
〓”,
It has a "BM" function. The above "E←→J" means from English to Japanese (E→J), or from Japanese to English (J→
With the key for specifying the translation mode E), the translation modes "E→J" and "J→E" are alternately switched each time the key is operated. However, when switching to the translation mode by the mode switch 6, the mode is first "E→J", and then the mode is alternately switched as described above by key operation "E←→J". "TR" is the key that commands translation, "IN" is the initial of the word, or in the case of "E→J" mode, A, B, C...
………, in the case of “J → E”, the search key is read out and displayed from the dictionary memory described later in order every 0.5 seconds, “RE” is the above This is a search key that reads and displays initials in the reverse order of the "IN" key. "▼", "〓"
is a key that commands a forward search for a word.If the operation is instantaneous, the key will search one word for each operation, but if the operation is continued for more than a set time, for example 2 seconds or more, the search will be performed for 0.5 seconds after 2 seconds have elapsed. , word searches are performed at intervals of 0.25 seconds. ``▲'' and ``〓'' are keys that command backward search for words, and if they are pressed continuously for more than 2 seconds, they will be searched for 0.5 seconds and 0.25 seconds after 2 seconds have elapsed, similar to the ``▼'' key and ``〓'' key. Perform a word search at intervals. "BM" is a bookmark key, and for example, when memorizing English words from the beginning, it acts as a "bookmark" to the point you have memorized. By operating the "BM" key alone, the address of the word being displayed can be stored, and by operating the "AC" and "BM" keys, the marked word can be called up. In addition,
The "MR" key and the "M+" key have no function in translation mode. Furthermore, the "AC" key (all clear key), "C" key (clear key), and numeric keypad retain their functions even in translation mode.

Next, the configuration of the electronic circuit will be explained with reference to FIG. Key operation signals input from the keyboard 3 are sent to the key discrimination section 11. This key discrimination section 11 transfers the input key operation signal to the control section 12, discriminates its contents, and sends a signal a which becomes "1" when the translation mode is specified to the one-shot circuit 13 and the AND circuit. Output to 14,
A signal b which becomes "1" by operating the "E←→J" key is output to the AND circuit 14. And circuit 1
The output of 4 is input as a count signal to the binary counter 15, and the one shot pulse output from the one shot circuit 13 is input to the binary counter 15.
5 as a reset signal. Also, when the "AC" key is operated, the signal i is transmitted to the key discriminator 1.

f, g, and h are output and input to the search control section 16 shown in detail in FIG. On the other hand, the control section 12
has output lines 12a to 12d, output line 12a outputs a control signal to display selection section 17, and output line 12b outputs calculation data and control signals in calculation mode to calculation/storage section 18. Note that the control signal sent from the control unit 12 to the display selection unit 17 via the output line 12a includes numeric keypad data and display data for “E→J” and “J→E” in the translation mode. It can be done. Further, the control unit 12 outputs a control signal from the output line 12c to the address decoder 19, and outputs numeric keypad data, arithmetic control data, read/write commands, etc. to the search control unit 16 from the output line 12d, as detailed later. do. Then, address data is sent from the search control section 16 to the first dictionary memory 20 and the second dictionary memory 21 via the address decoder 19.

There is.
In the addresses EI1 to EI26, data relating to initials, that is, the number of words of each term of the alphabets A to Z, is written in the first storage area 20a. For example, if the words in the A section are 124 words, "A=124W" is written in the address of EI1. Furthermore, within the addresses EW1 to EW2209, 2209 English words are written in the first storage area 20a from the A term to the Z term in alphabetical order.
Furthermore, the start address data of each item of the memorized English words is written in the second storage area 20b at addresses EI1 to EI26. For example, since the A term starts at address EW1, "EW1" is written in the address of EI1 as the corresponding address, and
Since the term starts at address EW125, "EW125" is written in the address of EI2 as the corresponding address. Then, the corresponding translation word, that is, the corresponding address of the Japanese word stored in the second dictionary memory 21 is written in the second storage area 20b at the addresses EW1 to EW2209. On the other hand, the second dictionary memory 21 stores JI1 to JI1 as shown in FIG.

Furthermore, within the addresses JW1 to JW2209, 2209 Japanese words (words) from A to W are written in the first storage area 21a in alphabetical order, and in the second storage area 21b. The corresponding translation word, that is, the corresponding address of the English language stored in the first dictionary memory 20 is written. Note that the above-mentioned "EI", "EW", "JI", and "JW" are each written as a code number.

Therefore, the address data read from the second storage area 20b of the first dictionary memory 20
Address data read from EW, JW and second storage area 21b of second dictionary memory 21

Next, details of the key discrimination section 11 shown in FIG. 2 will be explained with reference to FIG. 3. Key operation signals c to h are sent from the key discrimination unit 11 to the search control unit 16, and these signals c to h are sent to the one-shot circuits 31 ₁ to 31 ₆ and the delay circuit 32, respectively.
₁ to 32 ₆ are input. The delay circuit 32 ₁ ~
₃₂₆ has a delay time of, for example, 2 seconds and is configured to inhibit output when the input signal becomes "0", and its delayed output is input to AND circuits ₃₃₁ to _336, respectively. . moreover,
The AND circuits ₃₃₁ to ₃₃₃ , ₃₃₅ receive a clock pulse _φ1 with a period of 0.5 seconds from the pulse generation circuit 34.
is input, and 0.25 is input to the AND circuits 33 ₄ and 33 ₆ .
A clock pulse _φ2 with a period of seconds is input. Then, one shot circuit ₃₁₁ and AND circuit 33
The output of ₁ is inputted to the +1 terminal of the initial address counting section 36 via the OR circuit 35a, and the output of the one shot circuit ₃₁₂ and the AND circuit ₃₃₂ is inputted to the -1 terminal of the initial address counting section 36 via the OR circuit 35b. input to the terminal. Furthermore, one-shot circuits 31 ₃ , 31 ₄ and AND circuits 33 ₃ ,
The output of ₃₃₄ is inputted to the +1 terminal of the word address counting section 38 via the OR circuit 37a, and is input to the one shot circuits ₃₁₅ , ₃₁₆ and the AND circuits ₃₃₅ ,
The output of ₃₃₆ is input to the -1 terminal of the word address counting section 38 via the OR circuit 37b. The initial address counting section 36 and the word address counting section 38 are supplied with count value set data from the control section 12 or the arithmetic circuit 39. Further, the word address counting section 38 is given the storage address from the bookmark storage section 40 as set data. Then, the initial address counting section 36 and the word address counting section 3
8. The bookmark storage unit 40 receives read/write commands R/W from the control unit 12, respectively.
Reading and writing are controlled by W1, R/W2, and R/W3. The initial address counting section 36 and the word address counting section 38 only set the data when the set data and the count signal are applied at the same time. The counts of the initial address counter 36 and word address counter 38 are input to the arithmetic circuit 39 and also sent to the address decoder 19 in FIG. 2. Furthermore, the count contents of the word address counting section 38 are input to the bookmark storage section 40. On the other hand, the arithmetic circuit 39 is supplied with an arithmetic control signal specifying addition or subtraction from the control section 12, and numeric keypad data is inputted via the input buffer 41. Data is read into this input buffer 41 when an address in the dictionary memories 20, 21 is directly designated by numerical values using a numeric keypad.

The search control unit 16 configured as described above is
In the translation mode, "IN", "RE", "▼", "〓",
It operates when the key operation signals c to h of "▲" and "〓" are given, and performs search control for the dictionary memories 20 and 21, but if each of the above keys is pressed for 2 seconds or less, the press operation Each time, the dictionary memories 20 and 21 are searched, and if the pressing operation is continuous for 2 seconds or more, the dictionary memories 20 and 21 are searched at the time of operation.
After 2 seconds have elapsed, the dictionary memories 20 and 21 are searched at intervals of 0.5 seconds or 0.25 seconds. That is, the pressing operation of each of the above keys is as shown in FIG. 6a.
As shown in , if it is 2 seconds or less, the delay circuit 32 ₁
~32 ₆ output is “0” and AND circuit 33 ₁ ~3
The gates of 3 and ₆ are closed, and therefore the one-shot circuit 3 is closed in response to key operation as shown in Figure 6b.
Only the one-shot pulses output from ₁₁ to ₃₁₆ are sent to the initial address counting section 36 or the word address counting section 38. Therefore, the initial address counting section 36 and the word address counting section 38 perform a counting operation and search the dictionary memories 20 and 21 every time the key operation is performed.
However, if the keys ``IN'', ``RE'', ``▼'', and ``▲'' are operated continuously for more than 2 seconds as shown in Figure 6c, then when the key operation signal rises, As shown in d, one-shot circuits 31 ₁ to 31
A one-shot pulse is output from ₃ , 31 ₅ , and after 2 seconds delay circuits 32 ₁ to 32 ₃ , 32
AND circuits 33 ₁ to 33 ₃ , 33 by the output of ₅
The gate of ₅ is opened and the gate of 0.5 is opened as shown in Figure 6e.
A clock pulse φ ₁ with a period of seconds is output and sent to the initial address counter 36 and the word address counter 38 . Therefore, the initial address counting section 36 and the word address counting section 38 search the dictionary memories 20 and 21 once when a key is operated, and then search the dictionary memories 20 and 21 every 0.5 seconds after 2 seconds have elapsed.
Search for 21. In addition, if the keys "〓" and "〓" are operated continuously for more than 2 seconds as shown in _FIG . ,31 ₆
One shot pulse is output from
Seconds later, the gates of the AND circuits ₃₃₄ and ₃₃₆ are opened by the outputs of the delay circuits ₃₂₄ and ₃₂₆ , and a clock pulse _φ2 with a period of 0.25 seconds is generated as shown in FIG.
is output and sent to the initial address counting section 36 and word address counting section 38. Therefore, the initial address counting section 36 and the word address counting section 38 read the dictionary memory 20,
21, and after 2 seconds have elapsed, the dictionary memories 20 and 21 are searched every 0.25 seconds.

Next, the operation of the translation function of the embodiment configured as described above will be explained. First, the operation of the initial search will be explained with reference to FIG. When specifying the translation function, the mode switch 6 is switched to the translation mode TR as shown in FIG. 7a. When the translation mode TR is designated by the mode switch 6, a signal designating the translation mode is sent from the key discrimination section 11 in FIG. 2 to the control section 12.
In addition, the key determination unit 11 outputs “1” in translation mode.
A signal a is output to the one-shot circuit 19, and at its rising edge, the one-shot circuit
A one-shot pulse is output from 1, and the binary counter 15 is reset. When the binary counter 15 is reset, the control section 12 outputs display data of "E→J" indicating the English to Japanese translation mode from the output line 12a, and provides it to the display selection section 17. The display data of "E→J" is sent from the display selection section 17 to the character generator 22, converted into dot pattern data, and sent to the liquid crystal drive section 24 via the display buffer 23. Then, by this liquid crystal driving section 24,
The liquid crystal display section 2 is driven and the translation mode display section 2a is displayed.
As shown in FIG. 7a, the "E→J" translation mode is displayed. When performing an initial search, the user then operates the initial key "IN" as shown in FIG. 7b. When this initial key “IN” is operated, the key discriminator 1
The control section 12 operates according to the key operation signal from the search control section 16 via the output line 12d.
gives control signals and set data to That is, the control unit 12 controls the initial address counting unit 36 of the search control unit 16 whose details are shown in FIG.
A read/write command R/W1 instructs writing, and provides initial head address data "EI1" to the first dictionary memory 20 as set data. As a result, address data "EI1" is set in the initial counting section 36.
Also, at this time, the key determination section 11 gives the search control section 16 a signal c which becomes "1" while the initial key "IN" is pressed, and a one shot pulse is output from the one shot circuit ₃₁₁ . However, when the data setting operation is being performed as described above, the "+1" operation is not performed. The data set in the initial address counting section 36 is then sent to the address decoder 19, where it is decoded in accordance with a control signal from the control section 12. That is, the address decoder 19 decodes the initial address counting section 36 based on the control signal from the control section 12, and designates the first address "EI1" of the first dictionary memory 20 based on the decoded output. By this address designation, the content "A=124W" stored in the first storage area 20a is read out, and the display selection section 17
sent to. In the E→J translation mode, the display selection section 17 selects the output of the first dictionary memory 20 according to the command from the control section 12 until the translation key "TR" is operated. . Therefore, the data read from the first dictionary memory 20 is sent to the character generator 2 via the display selection section 17.
Sent to 2. As a result, as shown in FIG. 7b, the liquid crystal display section 2 displays "A=124W", that is, 124 words starting with "A" are stored. In this state, when the initial key "IN" is operated as shown in FIG. 7c, the signal c is output from the key discrimination section 11 as described above.
It is sent to the search control section 16. In this search control section 16, the one-shot circuit ₃₁₁ operates when the signal c is applied, and the one-shot pulse is inputted to the +1 terminal of the initial address counting section 36 via the AND circuit 35a. As a result, the contents of the initial address counting section 36 become “+
1” and its contents become “2”. By adding "+1" to the content of this initial address counting section 36, the next address "EI2" of the first dictionary memory 20 is designated, and its stored content "B=
107W” is read out to the display selection section 17. As a result, the liquid crystal display section 2 displays "B" as shown in FIG. 7c.
=107W" is displayed. Thereafter, in the same manner, each time the initial key "IN" is operated, the next address of the first dictionary memory 20 is designated and its stored contents are read out. As a result, as shown in FIG. 7d to e, the liquid crystal display section 2 displays "C=159W" to "L
Initial data such as "=72W" will be displayed. In this case, if each operation of the initial key "IN" takes less than 2 seconds, the contents of the initial address counter 36 are incremented by "+1" each time the key is operated, and the next address in the first dictionary memory 20 is sequentially specified. , If the initial key "IN" is pressed continuously for 2 seconds or more, the contents of the initial address counter 36 will change to "+" at 0.5 second intervals after 2 seconds as described above.
1” is done. Therefore, the initial data displayed on the liquid crystal display section 2 is updated every 0.5 seconds.

Also, if you want to perform the above initial search in the opposite direction, operate the reverse key "RE". For example, if you perform an initial search from "A" to "L" as shown in FIG. 7e, and then operate the reverse key "RE" as shown in FIG. A signal d for the ski "RE" is output and sent to the search control section 16. When the search control section 16 receives the signal d, it outputs a one shot pulse from the one shot circuit ₃₁₂ and inputs it to the -1 terminal of the initial address counting section 36 via the OR circuit 35b. As a result, the count content of the initial address counting section 36 is decremented by 1, and the address designation of the first dictionary memory 20 returns from "L" to the previous "K". Therefore, the initial data "K=14W" for "K" is read out from the first dictionary memory 20 and displayed on the liquid crystal display section 2 as shown in FIG. 7f. Similarly, reverse key "RE"
Each time the initial address counter 36 is operated, the contents of the initial address counter 36 are incremented by "-1", the contents of the previous address are sequentially read from the first dictionary memory 20, and the contents of the initial address counter 36 are read out sequentially from the first dictionary memory 20.
The screen is displayed as shown in FIGS. 7g to 7h.
Figure 7g shows the initial data of “J” “J=
15W'', and FIG. 7h shows a display example of the initial data of ``C'', ``C=159W''. in this case,
If the reverse key "RE" is operated for less than 2 seconds, the contents of the initial address counter 36 are incremented by "-1" every time the key is operated, and the previous address of the first dictionary memory 20 is sequentially specified. If the ski "RE" is operated continuously for more than 2 seconds, the clock pulse _φ1 will be activated after 2 seconds as described above.
The contents of the initial address counter 36 are incremented by "-1" at intervals of 0.5 seconds. Therefore, the initial data displayed on the liquid crystal display section 2 is "A" every 0.5 seconds.
Go back in the direction of. In this way, an initial search in the reverse direction is performed.

The above is a case of performing an initial search in English, but when performing an initial search in Japanese, first operate the "E←→J" key to translate as shown in Figure 7i. Change the mode from Japanese to English mode. That is, when the "E←→J" key is operated in the above English to Japanese translation mode, the key discrimination section 11 outputs a signal b which becomes "1" due to the above key operation, and the signal b is sent to the AND circuit 14. is input. In this case, in the translation mode, the signal a is output from the key discriminator 11 and given to the AND circuit 14, so the output of the AND circuit 14 becomes "1" due to the signal b.
The binary counter 15 performs an inverting operation. As a result, the output of the binary counter 15 becomes "1", and the "1" signal output is sent to the control section 12. When the output of the binary counter 15 becomes "1", the control section 12 enters the translation mode from Japanese to English, and outputs the output from the display selection section 1 via the output line 12a.
The display data of "J→E" is output to 7. Therefore, the translation mode "J→E" is displayed on the liquid crystal display section 2 as shown in FIG. 7i. Further, the control section 12 gives a control signal to the display selection section 17 to select the output of the second dictionary memory 21 via the output line 12a. At this time, since the second dictionary memory 21 is not addressed, the display on the liquid crystal display section 2 is "0". In this state, press the initial key "IN" as shown in Figure 7j.
When operated, a key operation signal for the initial key "IN" is sent from the key discrimination section 11 to the control section 12. After switching to the translation mode from Japanese to English, the control unit 12 presses the initial key “IN”.
For the first operation, initial head address data "JI1" is given to the initial address counter 36, and a write command R/W1 is given. As a result, address data "JI1" is set in the initial address counting section 36. The contents of this initial address counter 36 are sent to the address decoder 19 and decoded. and,
The decoded output of the address decoder 19 specifies the initial start address "JI1" of the second dictionary memory 21, and the content "A=34 go" stored in the first storage area 21a is read out, and the display selection is performed. Sent to Department 17. At this time display selection section 17
As described above, since the second dictionary memory 21 is switched by the control signal from the control section 12, the data read from the second dictionary memory 21 is selected and the character generator Transfer to 22. Therefore, as shown in FIG. 7J, the initial data of "A=34GO" is displayed on the liquid crystal display section 2. Subsequently, when the initial key "IN" is operated as shown in FIG. be done. Therefore, the next address "JI2" of the second dictionary memory 21 is specified,
The memory content "Ini 26" is read out and is shown in Figure 7k.
It is displayed on the liquid crystal display section 2 as shown in FIG. In this state, when the reverse key "RE" is operated as shown in FIG.
The address designation in the dictionary memory 21 returns from "A" to the previous "A", and the initial data "Ani34" for "A" is displayed on the liquid crystal display section 2.

In addition, if you want to return the above Japanese to English translation mode to English to Japanese translation mode, as shown in Figure 7 m, by performing the key operation "E←→J", the above As shown, the binary counter 15 is inverted, and the English to Japanese translation mode is designated. At this time, the display data of "E→J" is sent from the control section 12 to the display selection section 17 via the output line 12a, and the display data of "E→J" is sent from the control section 12 to the display selection section 17 via the output line 12a.
→J” translation mode is displayed. The control unit 12 also sends the first dictionary memory 2 to the display selection unit 17.
A control signal is sent to select 0, and the selection function is switched.

However, when performing the initial search not from the first "A" but from the last "Z", after switching the translation mode as shown in Figure 7m,
Operate the reverse key "RE" as shown in Figure 7m. The control unit 12 controls the initial address counting unit 36 for the first operation of the reverse key “RE”.
The initial final address data "EI26" of the first dictionary memory 20 is given to the first dictionary memory 20, and a write command R/W1 is given to the first dictionary memory 20. As a result, address data "EI26" is set in the initial address counting section 36, and the first address data is sent via the address decoder 19.
The initial final address "EI26" of the dictionary memory 20 is specified. As a result, the initial data of "Z" is transferred from the first dictionary memory 20 to "Z=
1W'' is read out and displayed on the liquid crystal display section 2 as shown in FIG. 7n. Next, when the reverse key "RE" is operated as shown in FIG. to return to the previous "Y",
Initial data “Y=7W” for “Y” is displayed on the liquid crystal display section 2. Thereafter, in the same manner, each time the reverse key "RE" is operated, an initial search is performed in the sending direction, that is, in the direction of "A". Also,
When searching from the final Japanese initial "wa", the initial search can be performed by operating the "E←→J" key and then performing a similar key operation.

Next, the word search operation for selecting and specifying each word will be explained with reference to FIG. First, the 8th
As shown in Figure a, the search control section 16 is set to the initial state by operating the "AC" key. In this initial state, the counter 15 is reset by the signal i and the English to Japanese translation mode is designated. Next, operate the "▼" key as shown in FIG. 8b.
When the "▼" key is operated, the control unit 12 gives a write command R/W2 to the word address counting unit 38, and also writes the word at the beginning of the word in the first dictionary memory 20 in the English to Japanese translation mode. Give address "EW1". Therefore, word address counting section 3
The address data "EW1" is set to 8, and the stored content "A" of the first storage area 21a is read out from the first dictionary memory 20 and displayed on the liquid crystal display section 2. Next, as shown in Figure 8c, “▼”
When a key is operated, a signal e is sent from the key determination section 11 to the search control section 16. A one shot pulse is output from the one shot circuit ₃₁₃ in response to this signal e, and is inputted to the "+1" terminal of the word address counting section 38 via the OR circuit 37a. As a result, the content of the word address counting section 38 becomes "+1".
Then, the next address of the first dictionary memory 20 is designated, and its contents, for example, "ABILITY" are read out and displayed on the liquid crystal display section 2. In this case, if the "▼" key is operated continuously for more than 2 seconds, the contents of the word address counter 38 will be incremented by "+1" as described above, and after 2 seconds have elapsed, the clock pulse _φ1 will be applied. Then, the contents of the word address counter 38 are sequentially incremented by "+1" every 0.5 seconds.

Further, the numeric keypad data is sent from the control section 12 to the character generator 22 via the output line 12a and the display selection section 17, and is displayed on the liquid crystal display section 2. When the initial key "IN" is operated as described above in this state, the write command R/W1 is output from the control section 12, and the numerical data "2" held in the input buffer 41 is transferred via the arithmetic circuit 39. It is written into the initial address counting section 36. Also, at this time, the control unit 12 outputs the code “EI”, and the initial address counting unit 36
is set to As a result, "EI2" is set in the initial address counting section 36, and the initial address "EI2" of the first dictionary memory 20 is designated via the address decoder 19. As a result, the initial data "B=107W" for "B" is read out from the first dictionary memory 20, and the initial data "B=107W" is read out from the first dictionary memory 20, and
It is displayed on the liquid crystal display section 2 as shown in FIG. Also,
For example, as shown in Figure 10d, enter the numerical data "14" by operating the numeric keypad 4, and then
When the initial key "IN" is operated as shown in Figure e, the initial address of "EI14", that is, "N" is specified to the first dictionary memory 20 in the same manner as in the above case, and the initial address is Data, for example, "N=52W" is read out and displayed. If you want to search for a word at a specific address in the "N" section, use the numeric keypad 4 to search for a word at a specific address, for example "12" as shown in FIG. , and then operate the "▼" key as shown in Figure 10g. By operating the numeric keypad, the numerical data is first stored in the input buffer 41 from the control unit 12 as described above. Next, by operating the "▼" key, the contents of the second storage area 20b at the specified address, that is, the word address data "EW1680" for "N" are read out from the first dictionary memory 20, and the word address data is read out via the control unit 12. It is set in the counting section 38. The data set in the word address counting section 38 is further sent to the arithmetic circuit 39 and added to the numerical data "12" held in the input buffer 41 according to the arithmetic control signal from the control section 12. The result of this addition is the word address counting section 38
is sent to and set. Then, the address of the first dictionary memory 20 is specified according to the data set in the word address counting section 38,
The 12th word data from the first word in the "N" section, for example "NEED", is read out and displayed.

Also, when addressing a word in the "A" section, there is no need to perform an initial search;
After operating the “AC” key as shown in Figure 0h,
As shown in FIG. 10i, a desired address, for example "40", is specified using the numeric keypad 4, and then the "▼" key is operated as shown in FIG. 10j. By the above key operations, the numeric keypad data "40" is set in the word address counting section 38 via the input buffer 41 and the arithmetic circuit 39 together with the "EW" code from the control section 12, and from the beginning of the first dictionary memory 20. The 40th word address is specified, and its contents, for example "AID", are read and displayed. Also,
Similarly, after operating the "AC" key as shown in Figure 10k, specify the address "25" with the numeric keypad 4 as shown in Figure 10l, and then

and the contents of the word address counting section 38 are added, and the addition result is set in the word address counting section 38 again. Therefore, the sixth address from the address storing the word "ADDRESS" is specified for the first dictionary memory 20, and its stored content, for example "ADVANTAGE", is read out and displayed. If you enter a numerical value using the numeric keypad 4 while words are displayed in this way, and then operate the "▼" key, the memory address will be advanced by the specified numerical value, and the contents will be read from memory and displayed. Ru. The search for initial data and word data by addressing as explained in FIG. 10 above is performed in the same way in the Japanese to English translation mode.

Next, the bookmark storage operation will be explained with reference to FIG. This bookmark has a function corresponding to a ``bookmark'' that is generally used when reading a book, and is used when memorizing English words sequentially from the beginning. Now, for example, as shown in FIG. 11a, operate the "AC" key to initialize, and then, as shown in FIG. 11b to c, perform a word search by operating the "〓" key etc. When learning by sequentially displaying ``PAGE'' on the liquid crystal display section 2, if you want to interrupt the learning when you have learned up to ``PAGE'', operate the bookmark key ``BM'' as shown in FIG. 11d. When this bookmark key "BM" is operated, a write command R/W3 is output from the control section 12 to the bookmark storage section 40, and the count contents of the word address counting section 38 at that time, that is, the word address data for "PAGE" is written into the bookmark storage section 40. In this way, bookmark storage is performed by operating the bookmark key "BM". If the user wants to resume learning at a later date, in the translation mode, first operate the "AC" key, and then operate the "BM" key, as shown in FIG. 11e and f. When the "AC" and "BM" keys are operated, the control section 12 sends a write command R/W2 to the word address counting section 38 and a read command R/W3 to the bookmark storage section 40.
The address data for "PAGE" stored in the bookmark storage section 40 is read out and written into the word address counting section 38. Next, a read command R/W2 is output from the control section 12, the contents of the word address counting section 38 are read out to the address decoder 19, and the address of the first dictionary memory 20 is designated. By this address specification, the word data "PAGE" is read out from the first dictionary memory 20 and displayed on the liquid crystal display section 2 as shown in FIG. 11f. From this state, as shown in FIG. 11g, by operating the "▼" key, a search for the word following "PAGE" is performed.

On the other hand, the mode switch 6 on the keyboard 3
