Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to an electronic learning machine, and in particular provides an electronic learning machine suitable as a learning machine for students to use when learning English.

<Prior art> Conventionally, electronic translation devices that can be used for English learning are pre-recorded with essential words that junior high school students must memorize, and they are mainly used to learn words based on this linguistic information. It was something to do. However, English learning for junior high school students and others is mainly done through textbooks used at school, and it is desirable for them to study along with these textbooks. Conventional electronic translation devices have some disadvantages when used as learning machines for studying school textbooks.

<Object and outline of the invention> The present invention has been made in view of the above points,
For each of the multiple criteria that can be selected from the common language data, all the languages included in that criteria are divided into blocks, and for each divided block, the languages included in that block are By dividing the concept into multiple groups of lower-level concepts than the above-mentioned standard concept and selecting and specifying the above-mentioned block and the above-mentioned group, it is possible to accurately recall the languages belonging to the desired group from the above-mentioned common language data in a predetermined order. This is how it was done.

This can be explained using a specific example as follows.

As linguistic data, we first edit the words and idioms from the English textbooks designated by the Ministry of Education used in junior high schools across the country, and then this content can be compiled into New Horizons, New Prince, New Crown, New Horizons, New Prince, New Crown, etc.
Classified into five types of textbooks: New Everyday and Total English. Then, each textbook is divided into 1st grade, 2nd grade, and 3rd grade, and further divided by lesson number for each grade textbook, and words and phrases that appear in these lessons are recorded. However, since the same words may appear even in different textbooks, it is important to store these words without duplication due to memory capacity constraints. In addition, textbooks are lessons (hereinafter referred to as ``sections'').
In addition to the section ``Review,'' for example, it is important to memorize the words and phrases that appear in this section. This will become clear in the explanation of the example, but for example, after the second lesson (3
(before the lesson) If there are learning items other than the normal lesson,
This can be indicated by a display such as "L2-1 (1 year)". Furthermore, the language data can be used as dictionary data regardless of textbook or grade level, and can also be used as a normal dictionary.

<Embodiment> FIG. 1 is a plan view showing the appearance of an electronic learning machine with a calculation function which is an embodiment of the present invention.

In the figure, 1 is a power on/off and mode selection slide switch, which has the following positions: off, calculation, English-Japanese, and Japanese-English.

Reference numeral 2 is a textbook selection key, which is used to select one of the five types of English textbooks designated by the Ministry of Education and used in junior high schools nationwide. Since this key only needs to be operated once after inserting the battery, it is operated with the tip of a pen, etc., as shown in the figure, and is normally not touched carelessly. Specifically, each time this key is pressed, textbook names are displayed in sequence. 3
is a key that functions as a division key in calculation mode and as a "section designation key" in English-Japanese or Japanese-English mode. When functioning as a section designation key, the grade and section number (so-called lesson number)
Used to specify. A key 4 functions as a recall memory/clear memory key in the calculation mode, and as a "lesson order key" in the English-Japanese or Japanese-English mode. When functioning as a lesson key, it is used to sequentially call up the words of the already specified grade and section number. 5
is a key that functions as an equal key in calculation mode, and as a "translation key" in English-Japanese or Japanese-English mode.

6 is the initial letter (first letter) of the headword to be searched
By pressing this key a predetermined number of times, characters in alphabetical order or alphabetical order can be specified. 7 is the second character from the beginning of the headword to be searched (second character)
This is a key for specifying a character, and by pressing this key a predetermined number of times, a desired character can be similarly specified. 8 is a key for searching for a word containing the first character string specified in this way.

Reference numeral 9 denotes a textbook name printing section in which the official names of the five types of English textbooks are printed in advance in the order called up by operating the textbook selection key 2. Note that the textbook name called up and displayed by operating the textbook selection key 2 is displayed in an abbreviated form.

10 is a liquid crystal dot matrix display section.

FIG. 2 is a block diagram showing the system configuration of this device.

In the figure, DISP is the display section 10, DSC is a display control circuit, a display memory that stores information to be displayed in a bit pattern corresponding to the dot pattern of the display section, and this display memory. The circuit includes a circuit that generates a segment signal according to the contents of the segment signal, and a circuit that generates a back plate signal. ROM is a read-only memory that stores control information such as programs and language information in advance. RAM is random access memory and is used for various buffer registers, flags, etc. The CPU is a control circuit that is connected to each of these units via address bus AB, data bus DB, and control bus CB, and performs information control. KEY is the key input section,
SW is slide switch 1.

FIG. 3 shows the contents of the ROM. 4 to 6 show some blocks in FIG. 3 in detail.

First, in FIG. 3, "program" is an area that stores program instructions. The "first grade address" is an address table that stores the first address in the "section search first address" for each grade for each textbook. The "section search start address" is an address table that stores the start address in the "section search table" of each section for each grade of each textbook. The "section search table" is a table that stores word numbers of words that appear in each textbook in order. "Language data" is an area that stores information on the final target word. "Others" is an area for storing, for example, characters and patterns.

Figure 4 shows the contents of the "Section search start address", and as shown, for each textbook (KI: Textbook 1, K2: Textbook 2,..., K5: Textbook 5),
From the first lesson (1st lesson) in the 1st grade to the last lesson in the 3rd grade (1L1: 1 lesson in 1st grade, 1L2: 2 lessons in 1st grade,
1L2-1: 1st grade, 2-1 division, 1L3: 1st grade, 3 divisions,
…, 2L1: 2nd grade 1st grade, 2L2: 2nd grade 2nd grade, …,
3L10-2: 3rd grade, 10-2 lessons, 1L1: 1st grade, 1 lesson,
1L2: 1st grade, 2 divisions, ..., 3L12: 3rd grade, 12 divisions) The start address is memorized. This start address is the "section search table" as shown above.
This is the first address in . The most significant bit of this content is a bit for identifying whether it is the first section of the school year, and if it is "1", it represents the first section of the school year. The second upper bit is a bit for identifying whether it is a normal section or a special section between sections, and if it is "1", it represents a special section.

FIG. 5 shows the contents of the above-mentioned "section search table", and as shown, word numbers are stored in order for each textbook. This order is the order of grades, the order of sections, or the order of appearance within a section within a textbook. Based on this word number, a predetermined word in the "language data" is read out.

FIG. 6 shows the contents of the above-mentioned "language data", and as shown in the figure, the first language, English, and the second language, Japanese, are stored in a connected manner. Here, the additional information is information such as accent information of English words, the presence or absence of variations of English words, and the presence or absence of idioms.

This information is arranged in alphabetical order based on English. Therefore, regarding Japanese
When searching in alphabetical order, a table in alphabetical order is required. “Japanese search table” in Figure 3
is the table for that purpose. The "English search table" shown in Figure 3 is used to search for headwords (English) containing the first two characters by specifying the first two characters, and the word number of the first word for each two characters is remembered.

7 to 9 and 11 to 17 are flowcharts showing the processing procedure performed by executing the instructions of the above program.

First, when the slide switch 1 is operated and the power is turned on, the states of the keys and the slide switch are read and determined as shown in FIG. Depending on the result of this determination, each process shown in FIGS. 8, 9, and 11 to 17 is performed.

Each process will be explained below.

As shown in FIG. 8, when the mode is switched to English-Japanese mode, flag FE is set. FE=1 indicates English-Japanese mode, and FE=0 indicates Japanese-English mode. Next, the textbook number is read and the name of the textbook corresponding to that number is displayed. This textbook number is
It is stored in a predetermined area of RAM, has already been set, and is backed up by the battery even when the power switch is turned off. In the same figure,
F1 is a flag indicating that the textbook name is displayed.

FIG. 10 shows an example of key and slide switch operations and displays. In the above case, the textbook name is displayed as shown in 1.

Now, when the slide switch is switched to the Japanese/English mode, the flag FE is reset as shown in FIG. The subsequent processing is the same as above.

Further, when the slide switch is switched to calculation mode, computer processing is performed as shown in FIG.

Next, if the textbook selection key is pressed, the 11th
As shown in the figure, flags F2, F3, and F4 are reset. Each of these flags is a flag indicating that a specific display state is reached by pressing each key to be described later, and those states are reset by pressing this textbook selection key. Next is Flag F1
The state of is determined. In this state, as mentioned above, F1=1 has already been set, so the textbook number is updated. Specifically, the textbook number is counted up, and each time a key is pressed, it increases from 1 to 2.
→3→4→5→1→2→…recycle.
Next, the textbook name corresponding to the updated textbook number is displayed, and flag F1 is set (a3
→a4→a5). Furthermore, the grade and section numbers are initialized. In other words, it is set to the number of the first section of the first grade. The word point is also initialized. This word pointer is a pointer to the above-mentioned "section search table" and indicates which word was read last time. In short, when a textbook is selected, the position of such words within a grade, division, or section is returned to the beginning of each textbook. (a6 → a7).

By operating this textbook selection key, the textbook name is displayed as shown in FIGS. 2 and 3.

Furthermore, if the textbook selection key is pressed with F1 = 0, that is, no textbook name is displayed, the already memorized textbook number is read and the corresponding textbook name is displayed (a2 → a8 → a4). .

Now, after the desired textbook has been set in this way, if the section designation key is operated, the flags F1, F3, and F4 are first reset as shown in FIG. This is to indicate that various display states are not displayed by other key operations, and is similar to a1 in FIG. 11 above. Subsequently, flag F2 is determined. If F2=0, that is, the grade and section numbers are not displayed, the already stored grade and section numbers are read from a predetermined RAM area and displayed (b1→b2→b3→b4).

FIG. 10 4 is an example of this. This means first grade lesson 1.

Next, flag F2 is set and the word pointer is initialized (b5→b6).

In this state, if you press the section designation key again,
Since F2=1, the grade and section numbers are updated. The grade and division number will then be displayed.

FIGS. 5-6 are examples of this.

If you have passed the final lesson of the third grade,
Set in the first lesson of the school year (b2→b7).

In this way, after the grade and division numbers are selected,
When the lesson order key is pressed, flags F1, F2, F3, and F4 are reset as shown in FIG. 13 for the same reason as above. Next, the word pointer is read, and the word with the word number specified by the pointer is read from the language data and displayed (c2 → c3 → c4
→c5).

FIG. 10 is an example of this.

Each time you press this key, the word pointer is updated in c6, so you can call up words that appear in the lesson one after another.

Since this word pointer is backed up in the memory in the same way as the grade, section number, and textbook number, even if the power switch is turned off, the word will be recalled from the previous word as shown in FIG. 10 and 11.

If the words are called one after another in this way, and the lesson order key is pressed again after calling the last word in the lesson, the grade and department number will be updated and the number will be displayed (c3→c7→ →c8).

FIG. 10 and 13 are examples of this.

In this way, the word pointer is updated by operating the lesson order key, and as a result, the determination as to whether a section or grade level has been completed is stored as a table in the "section search start address" shown in Figure 4 above. This is done by determining the match between each start address and the word pointer.

As shown in Figures 16 and 17 in Figure 10, once you call up the grade and division number by pressing the section designation key, the word pointer is initialized as shown in Figure 12, so the first word of the lesson is can be called.

After calling up the desired word, press the translation key, as shown in Figure 14, if the flag FE = 1, that is, in English-Japanese mode, the Japanese language and additional information stored in conjunction with the already called word will be read, Display as translated word (d1→d2→d3). Figure 10 18
is an example. If FE=0, that is, Japanese-English mode, English will be displayed as the translated word (d1→d4→
d3).

FIGS. 15, 16, and 17 show processing performed by key operations when searching the language data in alphabetical order or alphabetical order without distinction of textbook, grade, or section.

First, first character (first character) designation key 6 (〓〓
key), the flag F1,
F2 and F4 are reset. The flag F4 indicates that the second character designation key 7 (ⓓⓓ key), which will be described later, has just been pressed. Subsequently, flag F3 is determined. If F3=0, that is, this key 6 is pressed for the first time, an initial character code is input into the most significant digit R1 of register R in accordance with flag FE. If FE=1, that is, the English-Japanese mode, the code for the letter "a" is input, and if FE=0, that is, the Japanese-English mode, the code for the letter "a" is input. and,
The display is performed.

After that, if the first character designation key 6 is pressed, the contents of R1 are changed to the code of the next character in the character order. For example, if “a” becomes “b”,
If it is “a”, it will be changed to “i”.

In this way, the desired initial letter is set.

Next, if the second character is to be specified in the same manner, the second character specification key 7 (ⓓⓓ key) is pressed. FIG. 16 shows the operation, and the basic operation is the same as that in FIG. 15.

After setting the first two characters in register R in this manner, by operating the search key 8, each flag is reset, a word search is performed, and the results are displayed, as shown in FIG.

<Effects> As explained in detail above, according to the present invention, learning can be conducted according to each block (for example, by school) and according to each group (for example, grade level), which can be used by students when learning English. This makes it possible to obtain an electronic learning machine that is extremely suitable for
