Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic dictionary that electronically performs translation between different languages.

In recent years, electronic dictionaries with 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, such as English and Japanese. .

However, the above-mentioned conventional electronic dictionary has alphabet keys and kana keys on the keyboard, and words are specified by operating the keys.When word data is input by operating the alphabet keys or kana keys, The dictionary memory is searched according to the word data, matching data is detected, and the translation process is performed. However, if alphabet keys, kana keys, etc. are provided to specify words 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 an object of the present invention is to provide an electronic dictionary that allows a user to quickly select a desired word without the need for alphabet 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, reference numeral 1 denotes a case body, and 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. The liquid crystal display section 2 has a dot matrix configuration in which each digit is, for example, 5×7, and has a capacity of 10 digits. The liquid crystal display section 2 also displays English to Japanese (E).

Furthermore, the data read out from the first storage areas 20a and 21a of the first and second dictionary memories 20 and 21 are also sent to the display selection section 17. Further, output data from the calculation/storage section 18 is input to the display selection section 17 . This display selection section 17, according to the control signal from the control section 12,
Input data is selected and transferred to the character generator 22. The character generator 22 generates dot pattern data for numbers, alphabetic characters, and kana characters according to the input data, and sends it to the liquid crystal drive section 24 via the display buffer 23. The liquid crystal driving section 24 drives the liquid crystal display section 2 according to the data held in the display buffer 23, and displays numbers, alphabetic characters, or kana characters in a dot pattern. Next, the key discriminator 1 in FIG.
1 will be explained in detail with reference to FIG. 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, to 316 and the delay circuits 32 to 3, 2, respectively.
6. The delay circuits 32, -326 have a delay time of, for example, 2 seconds, and are configured to inhibit output when the input signal becomes "0", and the delayed outputs are output from the band circuits 3-3, -326. 336 respectively. Further, a clock pulse ◇・ with a period of 0.9 seconds is input from the pulse generating circuit 34 to the AND circuits 33, 333, 335, and a clock pulse ◇・ with a period 0.25 seconds is input to the AND circuits 33, 333, 335. 2 is input.
Then, a one-shot circuit 31, an AND circuit 33,
The output is inputted to the eleventh terminal of the initial address counter 36 via the blue circuit 35a, and is input to the one-shot circuit 31,
The output of the AND circuit 332 is inputted to one terminal of the initial address counter 36 via the OR circuit 35b. Also, the one-shot circuit 31. , 314 and the AND circuits 333, 334 are input to the 11th terminal of the word address counting section 38 via the OR circuit 37a, and the outputs of the one-shot circuits 315, 316 and the AND circuits 335, 336 are input via the OR circuit 37b. word address counting section 38
of? Input to 1 terminal. Count value set data is given to the initial address counting section 36 and the word address counting section 38 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. and the address counting section 36,
The word address counting unit 38 and the bookmark storage unit 40 are
The drafting and writing are controlled by drafting/writing commands R/W1, R/W2, and R/W3 given from the control section 12, respectively. The above initial address counting section 6
And the word address counting section 38 only sets data when the set data and count signal are applied at the same time. The counts counted by the initial address counting section 36 and the word address counting section 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 and subtraction from the control section 12, and also receives numeric keypad data via the input buffer 41. In this input buffer 41, the dictionary memory 20,
Data is loaded when the address of 21 is directly specified. In the translation mode, the search control unit 16 configured as described above sends information from the keyboard 3 through the key discriminating unit 11 such as "IN", "▼", "▼▼", "▲"
It operates when the key operation signals c to h of ▲▲” are given,
Search control is performed on the dictionary memories 20 and 21, but
If each of the above keys is pressed for 2 seconds or less, the dictionary memo IJ20, 21 is searched each time the key is pressed.
If the pressing operation is continuous for 2 seconds or more, the dictionary memories 20 and 21 are searched during the operation, and after 2 seconds, the dictionary memories 20 and 21 are searched at a 0.5 second cycle or a 0.29 page cycle. That is, if the pressing operation of each key is 2 seconds or less as shown in FIG. 6a, the delay circuit 32. ~326
When the output is "0", the gates of the AND circuits 33 and 338 are closed, so that only one-shot pulses are output from the one-shot circuits 31 and 316 in response to key operations, as shown in FIG. 6b. is the initial address counter 3
6 or is sent to 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 Fig. 6 c, at the rise of the key operation signal, as shown in Fig. 6 d. A one-shot pulse is output from the one-shot circuits 31, -313, 315, and two seconds later, the delay circuits 32-323,
AND circuits 33, to 333, 335 by the output of 325
The gate is opened and a clock pulse with a period of 0.5 seconds is outputted as shown in FIG. Therefore, the initial address counting section 36 and the word address counting section 38 search the dictionary memories 20, 21 once when a key is operated, and then search the dictionary memories 20, 21 every 0.5 seconds after 2 seconds have elapsed. In addition, if the "▼▼" key "▲▲" is operated continuously for more than 2 seconds as shown in FIG. 6f, the one-shot circuit 314 is activated as shown in FIG. , 316 outputs a one-shot pulse, and two seconds later the delay circuit 324 outputs a one-shot pulse.
, 326 open the gates of AND circuits 334 and 336, and as shown in FIG. . For this reason, the initial address counting section 36 and the word address counting section 38 search the dictionary memories 20, 21 once when a key is operated, and then search the dictionary memories 20, 21 every 0.29 seconds after 2 seconds have elapsed. Next, the operation of the translation function of the embodiment configured as described above will be explained. First, when specifying a translation function, which will be explained in the initial search operation with reference to FIG. 7, 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. Further, the key discriminator 11 outputs a signal a which becomes "1" in the translation mode to the one-shot circuit 19, and at the rising edge of the signal a, the one-shot circuit 13 outputs a one-shot pulse and the binary counter 15 is reset. This binary counter 1
5 is reset, the control unit 12 outputs the output line 12a.
"B→J" indicates the translation mode from English to Japanese.
The display data is outputted and given 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 front buffer 23. The liquid crystal display section 2 is driven by the liquid crystal drive section 24, and the "E→J" translation mode is displayed on the translation mode display section 2a as shown in FIG. 7a. Thus, when performing an initial search, the initial key "IN" is then operated as shown in FIG. 7b. When this initial key "..." is operated, the control section 12 operates according to the key operation signal from the key discrimination section 11, and provides a control signal and set data to the search control section 16 via the output line 12d. That is, the control unit 1
2 issues an issue/write command R/W to the initial address counting unit 36 of the search control unit 16 whose details are shown in FIG.
Writing is commanded by I, and initial head address data "EII" for the two first dictionary memories is given as set data. As a result, the address data "EII" is set in the initial counter 36.
At this time, the key discrimination unit 11 also tells the search control unit 16 that while the initial key “Melon” is pressed, “
1'' is given, the one-shot circuit 31,
A one-shot pulse is output from 1 and applied to the eleventh terminal of the initial address counter 36 via the OR circuit 35a, but when the data setting operation is being performed as described above, the operation ``r+1'' is not performed. Not possible. The data set in the initial address counting section 36 is then sent to the address decoder 19, and the data set in the initial address counting section 36 is sent to the address decoder 19, and
decoded according to control signals from That is, the address decoder 19 decodes the initial address counting unit 36 based on the control signal from the control unit 12, and uses the decoded output to designate the first address “EIL” of the first dictionary memory 20. The contents stored in the storage area 20a of 1 “
A=124W'' is extracted and sent to the display selection section 17. In the E→J translation mode, the display selection section 17 selects the output of the first dictionary memory 20 according to a command from the control section 12 until the translation key "TR" is operated. Therefore, the data read out from the first dictionary memory 20 is sent to the character generator 22 via the display selection section 17. As a result, as shown in FIG. 7b, "A=124W" on the liquid crystal display section 2, that is, "A"
It is displayed that 124 words starting with are stored. In this state, when the initial key "IN" is operated as shown in FIG.
In this search control section 16, the one-shot circuit 31 is operated by being supplied with the signal c, and a one-shot pulse is input to the 11 terminal of the initial address counting section 36 via the AND circuit 35a. As a result, the content of the initial address counter 36 becomes "11", and the content becomes "2". This initial address counting section 36
The contents of the first dictionary memory 2 are changed to "11".
The address “E12” next to 0 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=1" as shown in FIG. 7c.
07W" is displayed.

Thereafter, in the same manner, each time the initial key "IN" is operated, the next address in the first dictionary memory 20 is designated and its stored contents are retrieved. As a result, as shown in FIG. 7d to e, the liquid crystal display section 2 displays "C=159W" to "L=72W
” and other initial data are displayed. In this case, if each operation of the initial key "IN" is performed for less than 2 seconds, the contents of the initial address counter 36 will be "11" each time the key is operated.
In this way, the next address of the first dictionary memory 20 is specified sequentially, but if the initial key "IN" is pressed continuously for more than 2 seconds, the address will be 0.9 after 2 seconds as described above.
The content of the initial address counter 36 is "11" at the sand interval.
” will be done. Therefore, the initial data displayed on the liquid crystal display section 2 is updated every 0.9 steps. Also, if you wish to perform the above initial search in the opposite direction, operate the reverse key "RE". Now, for example, as shown in Figure 7e, we are searching for initials from "A" to "L".
After that, if the reverse key "RE" is operated as shown in FIG.
A signal d for "E" 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 initial address counter 36 increments its count by 1, and
The address designation of the dictionary memory 20 returns from "rL" to the previous "K". Therefore, from the first dictionary memory 20
The initial data "K=14W" is displayed on the liquid crystal display section 2 as shown in FIG. 7f. Similarly, each time the reverse key "RE" is operated, the contents of the initial address counter 36 are incremented by one, the contents of the previous address are sequentially read out from the first dictionary memory 20, and the seventh address is displayed on the liquid crystal display section 2. It is displayed as shown in Figures g to h. Figure 7g shows the initial data of “J” “J=15W
", Figure 7h shows the initial data of "C""C=15
9W” is displayed. 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 designated. , If you operate the reverse key "RE" continuously for more than 2 seconds,
As mentioned above, after 2 seconds, the clock pulse ◇ causes 0.
．． The contents of the initial address counting section 36 are changed at intervals of 9 sands.
11” will be done.

Therefore, the initial data displayed on the liquid crystal display section 2 returns to the direction of "A" every 0.5 seconds. In this way, the initial search in the reverse direction is performed. The above is a case where an English initial search is performed, but if you want to perform a Japanese initial search, first operate the "E-Japanese J" key to change the translation mode to Japanese as shown in Figure 7-1. Change from Japanese to English.

That is, when the "EHJ" key is operated in the above-mentioned English to Japanese translation mode, the key discrimination section 11 outputs a signal b which becomes "1" due to the above-mentioned 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 signal b' causes the output of the AND circuit 14 to become "1", and the binary counter 15 becomes "1". Reverse 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 sends "" to the display selection section 17 via the output line 12a.
Output the display data of "J→E". Therefore, the translation mode "J→E" is displayed on the liquid crystal display section 2 as shown in FIG. 7i. The control unit 12 also controls the output line 1.
A control signal is given to the display selection section 17 via the terminal 2a to select the second output of the second dictionary memory 21. At this time, the second
Since the dictionary memory 21 of is not addressed, the display on the liquid crystal display section 2 is "ro". When the initial key "m" is operated in this state as shown in FIG. After switching to the Japanese-to-English translation mode, the control unit 12 gives the initial head address data “JII” to the initial address counting unit 36 in response to the first operation of the initial key “m”, and also issues a write command R/ Give WI. This results in
The initial address counting unit 36 contains address data “
JIL is set. The contents of this initial address counter 36 are sent to the address decoder 19 and decoded. Then, the decoded output of the address decoder 19 specifies the initial start address "JII" of the second dictionary memory 21, and the first storage area 21
The content "A=34go" stored in a is read out and 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 retrieved from the second dictionary memory 21. and transfers it to the character generator 22. Therefore, Figure 7i
As shown in the figure, the initial data of "A=34GO" is displayed on the liquid crystal display section 2. Subsequently, when the initial key "..." is operated as shown in FIG. ”
It's dirty. Therefore, the next address of the second dictionary memory 21 is "
J12'' is specified, and the stored content ``I=26go'' is displayed on the liquid crystal display section 2 as shown in FIG. 7k. In this state, when the reverse key "RE" is operated as shown in FIG. From “i” to the “a” before it
Returning to , the initial data for "A""A=34GO" is displayed on the liquid crystal display section 2. In addition, if you want to return to the above Japanese to English translation mode, as shown in Figure 7 m,
By operating the "EHJ" key, the binary counter 15 is inverted as described above, and the English to Japanese translation mode is designated.

At this time, output line 1 is sent from the control unit 12 to the display selection unit 17.
2a, the display data of "E→" is sent, and the translation mode of "E→J" is displayed on the liquid crystal display section 2. Further, the first dictionary memory 2 of the display selection section 17 is sent from the control section 12.
A control signal is sent to select 0, and the selection function is switched. Therefore, the initial search can be changed to the first "
If you want to start from the last "Z" instead of from "A", after switching the translation mode as shown in FIG. 7m, operate the reverse key "RE" as shown in FIG. 7n.

The control section 12 causes the initial address counting section 36 to input the first dictionary memory 2 in response to the first operation of the reverse key "RE".
The initial final address data "E126J" of 0 is given and the write command R/WI is given. As a result, the initial address counting section 36 receives the address data "E126J".
26'' is set, the address decoder ``E126'' is set, and the initial final address ``E156J'' of the first dictionary memory 20 is specified via the address decoder 19.

As a result, the initial data "Z=IW" for "Z" is extracted from the first dictionary memory 20 and displayed on the liquid crystal display section 2 as shown in FIG. 7n. Then, when the reverse key "RE" is operated as shown in FIG.
The address designation of the first dictionary memory 20 returns from "Z" to the previous "Y", and the initial data of "Y" is changed to "Y".
Y:7W” is displayed on the liquid crystal display section 2. In the same way, every time you operate the reverse key "RE", you move in the opposite direction.
In other words, an initial search is performed in the direction of "A". Also,
When searching from the Japanese final initial ``wa'', use ``
After pressing the EHJJ key, you can perform an initial search by pressing the same key. Next, the word search operation for selecting and specifying each word will be explained with reference to FIG.

First, as shown in FIG. 8a, 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 reset by the signal i,
Specifies the English to Japanese translation mode. Next, operate the "▼" key as shown in FIG. 8b. When the “▼” key is operated, the control unit 12 causes the word address counting unit 38 to
A write command R/W 2 is given to the address, and in the case of the English to Japanese translation mode, the word start address "EWI" of the first dictionary memory 20 is given. Therefore, the address data "EWI" 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. When the "▼" key is operated as shown in FIG. 8c, 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 input to the "111" 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 is "11", the address of the first dictionary memory 20 is designated, and its content, for example, "AB mountain ITY" is displayed, and the liquid crystal display section 2
is displayed. In this case, if the "▼" key is operated continuously for more than 2 seconds, the contents of the word address counter 38 will be "11" as described above, and after 2 seconds have elapsed, the clock pulse ◇ , the contents of the word address counter 38 are sequentially incremented by "11" 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. Also,
If you operate the “▲” key as shown in Figure 8 e,
