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 showing translation modes from English to Japanese (E→J) and from Japanese to English (J→E). In addition, the above keyboard 3
numeric keypad 4 for "0" to "9", decimal point key,
Function key 5 for specifying calculation content or translation processing content, mode switch 6 for switching between translation mode (TR) and calculation mode (CAL)
is provided. This mode switch 6 also serves as a power switch. The function keys 5 have different functions depending on the mode switch 6, that is, in the calculation mode and the translation mode. 3, each key has the function of the key name written corresponding to it. In other words, in translation mode, "E←→", "TR",
"IN", "RE", "▼", "▲", "〓", "〓", "
BM”
There is a function. The above "E←→J" is a key that specifies the translation mode from English to Japanese (E→J) or from Japanese to English (J→E).
The translation modes of "J" and "J→E" are switched alternately. 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 to command translation, “IN” is the initial of the word, “E
→J" mode, A, B, C, ..., "J" mode.
→ In the case of “E”, do A, I, U, E, O, etc. in that order.
The search key "RE" reads out and displays the initials from a dictionary memory, which will be described later, every 0.5 seconds, in the reverse order of the "IN" key. ``▼'' and ``〓'' are keys that command forward search for words.In the case of instantaneous operation, each word is searched one by one for each operation, but if the operation is continued for more than a set time, for example 2 seconds or more, After 2 seconds have elapsed, word searches are performed at intervals of 0.5 seconds and 0.25 seconds, respectively. "▲" and "〓" are keys that command backward search for words, and if pressed continuously for more than 2 seconds, "▼"
key, 0.5 each after 2 seconds in the same way as the “〓” key.
Word searches are performed at intervals of 0.25 seconds. "BM"
is the bookmark key, for example, when memorizing English words from the beginning, you can use the bookmark key to mark the points you have memorized.
to play the role of The address of the word being displayed is memorized by single operation of the above "BM" key, and "AC",
You can call up the marked word by pressing the "BM" key. Note that 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. 14, and a signal b which becomes "1" by operating the "E←→J" key is output to the AND circuit 14. And circuit 1

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 word is written in the second storage area 20b at addresses EI1 to EI26. For example, the A term is EW1
Since it starts from the address, "EW1" is written as the corresponding address in the address of EI1, and the B section is
Since it starts from 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 first storage area 20b at the addresses EW1 to EW2209. On the other hand, the second dictionary memory 21 stores JI1 to JI44 and JW1 as shown in FIG.

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 2 are searched at the time of operation.
Search for 1, and after 2 seconds, 0.5 seconds cycle or 0.25
Search control of the dictionary memories 20 and 21 is performed every second. That is, if the pressing operation of each of the keys is 2 seconds or less as shown in FIG. 6a, the delay circuit 32
When the output of ₁ to 32 ₆ is "0", the AND circuit 33 ₁ to
33 The gate of ₆ is closed, and therefore Fig. 6b
As shown in FIG. 3, only the one-shot pulses outputted from the one-shot circuits ₃₁₁ to ₃₁₆ in response to key operations 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, One-shot circuits 31 ₁ to 3 as shown in d
A one-shot pulse is output from 1 ₃ , 31 ₅ , and after 2 seconds the delay circuits 32 ₁ to 32 ₃ , 3
AND circuits 33 ₁ to 33 ₃ , 3 by the output of 2 ₅
3 The gate of ₅ is opened as shown in Figure 6e.
A clock pulse _φ1 having a period of 0.5 seconds is output and sent to the initial address counting section 36 and the word address counting section 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.
After that, after 2 seconds pass, dictionary memory 2 is added every 0.5 seconds.
Search for 0,21. In addition, if the keys "〓" and "〓" are operated continuously for more than 2 seconds as shown in _FIG . ,3
A one-shot pulse is output from ₁₆ , and after 2 seconds, the gates of AND circuits ₃₃₄ and ₃₃₆ are opened by the outputs of delay circuits ₃₂₄ and ₃₂₆ , and a pulse with a period of 0.25 seconds is output as shown in FIG. 6h. Clock pulse _φ2 is output and the initial address counter 3
6 and the word address counting section 38. For this reason, 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 once after 2 seconds have passed.
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 discrimination 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 start address "E11" 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.
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 input 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 contents of this initial address counting section 36, the next address "EI2" of the first dictionary memory 20 is designated, and the 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" and the next address in the first dictionary memory 20 is sequentially specified for each key operation. , 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←→" key to enter translation mode, as shown in Figure 7i. Change the mode from Japanese to English. That is, when the "E←→" 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 AND circuit 14
is input to. 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 signal b causes the output of the AND circuit 14 to become "1", and the binary counter 15 is inverted. Operate. 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 sends "J→
E" display data is output. Therefore, the translation mode "J→E" is displayed on the liquid crystal display section 2 as shown in FIG. 7i. In addition, the control unit 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 "O". In this state, Figure 7j
When the initial key "IN" is operated as shown in FIG.
After switching to the Japanese to English translation mode, the control unit 12 gives the initial head address data “JI1” to the initial address counter 36 in response to the first operation of the initial key “IN” and also issues a write command R/ Give W1. As a result, address data "JI1" is set in the initial address counting section 36. The contents of this initial address counting section 36 are stored in the address decode 19.
is sent to and decoded. Then, the decoded output of the address decoder 19 specifies the initial start address "JI1" of the second dictionary memory 21, and the content "A=34go" stored in the first storage area 21a is read out. It is sent to the display selection section 17. At this time, since the display selection section 17 is switched to select the second dictionary memory 21 by the control signal from the control section 12 as described above, the display selection section 17 selects the data read out from the second dictionary memory 21. character generator 22
Transfer to. 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, and its stored content "I=26go" is read out and displayed on the liquid crystal display section 2 as shown in FIG. 7k. In this state, press the reverse key "RE" as shown in Figure 7l.
When is operated, the contents of the initial address counter 36 are incremented by "-1" as described above, and the address specification in the second dictionary memory 21 returns from "A" to the previous "A". Initial data “A=34
” 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 7n. 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 reverse 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 keys "E←→J" and then performing the same 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 binary counter 15 is set 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
is a write command R/W2 to the word address counting section 38.
In addition, in the case of English to Japanese translation mode, the word start address "EW1" of the first dictionary memory 20 is given. Therefore, the address data "EW1" is set in the word address counting section 38, 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 FIG. 8c, when the "▼" key is operated, a signal e is sent from the key discrimination 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 contents of the word address counter 38 are incremented by "+1", 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. As a result, the contents of the first dictionary memory 20 are sequentially read out and displayed on the liquid crystal display section 2 as shown in FIGS. 8c to 8d. Furthermore, when the "▲" key is operated as shown in FIG. ,

The data is then sent to the search control section 16 shown in FIG. 3 and stored in the input buffer 41. 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 displayed on the liquid crystal display section 2 as shown in FIG. 10c. For example, if the numerical data "14" is input by operating the numeric keypad 4 as shown in Fig. 10 d, and then the initial key "IN" is operated as shown in Fig. 10 e, the result is the same as the above case. "EI14", that is, "N" for the first dictionary memory 20.
The initial address of ``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

is added to the contents of the word address counting section 38, 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.
It is stored in the bookmark storage section 40.
The address data for "PAGE" 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 specified. 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
When the calculation mode (CAL) is selected and specified, a control signal and calculation data are sent from the control unit 12 to the calculation/storage unit 18 by operating the numeric keypad 4 and function key 5, and predetermined calculation processing is performed. . In this case, the input number data and calculation result data are stored and held in the calculation/storage section 18 and sent to the character generator 22 via the display selection section 17, where they are displayed on the liquid crystal display section 2.

Note that in the above embodiment, the first dictionary memory 2
Instead of the address data JW written in the second storage area 20b of 0, write the corresponding Japanese (word) and write it in the first and second storage areas 21a and 21b of the second dictionary memory 21. Instead of the written Japanese (words) and address data EW, only address data obtained by rearranging the address data EW corresponding to the Japanese written in the second storage area 20b in the order of the Japanese dictionary is used. You can also write it down. By doing so, the overall storage area becomes smaller.

As described above, according to the present invention, the initial data, word data, etc. stored in the dictionary memory can be read out at will by specifying the address using the numeric keypad operation, so that the desired data can be read out without using the alphanumeric keys or the kana keys. It is possible to provide a search method in an electronic dictionary that can quickly select and display a word to be searched for, and can quickly search for a target word.
