Description

[Detailed description of the invention] The present invention relates to an electronic kanji learning machine.

Writing and reading kanji is essential for Japanese people, from elementary school students to working adults.

However, in everyday life, when we try to write a kanji, we often cannot think of a pattern, so we look it up in a dictionary. There are 38 kanji for general use that junior high school students learn.For example, when looking up the pattern for ``yellow'' in a dictionary, there are many kanji for ``ki'' and it is time consuming and tedious. In addition, "yellow" can also be used as "kou" or "ou".
There are 65 kanji for Tomo reading "Kou" and 14 for "Ou", and it is difficult to remember which reading is On-yoku or Kun-yoku, which can be a headache for elementary and junior high school students. be.

An object of the present invention is to provide an electronic kanji learning machine that can quickly search for a corresponding kanji.

An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows the front appearance of a kanji learning machine as an example of the present invention.The keyboard KB of this kanji learning machine includes a kana key K1, a kanji key K2, a reading key K3, a separator key K4, a liquid crystal display LC, etc. do. The liquid crystal display LC is composed of a dot matrix of 16 vertically and 53 horizontally, and can display one kanji character with 16 x 20 dots.
A total of 2 kanji characters can be displayed, and each kana character can be displayed as 8 x 8 dots, making it possible to display a total of 6 kana characters. In addition, the display LC is provided with a reading mark OY and a reading mark KY that identify the type of reading being displayed.

The kanji key K2 is a conversion key that converts the kana characters input and displayed by the kana key K1 into kanji characters, and the reading key K3 is a conversion key that displays the reading of the displayed kanji, the on-yomi mark OY, and the kun-yomi mark KY. key, separator key K4 is kana key K1
This is an input key that is pressed to separate the number of readings when inputting multiple readings of a kanji.

FIG. 2 shows an example of the circuit configuration of the present invention, in which data is input to the central processing unit CPU in accordance with the depression of keys K1 to K4. This central processing unit CPU uses a well-known ROM method.
Based on the data input from keys K1 to K4,
The character information stored in the fixed storage device M1 and the corresponding kanji pattern are recalled from the fixed storage device M2, and subjected to various signal processing, converted into a display signal, and guided to the display drive circuit DR, which sends a display drive signal to the display device LC. is applied to display kana or kanji on the display LC.

Next, I will explain the configuration of the central processing unit CPU.This central processing unit CPU has a control unit CONT and a read-only memory (ROM) in one chip LSI.
M3, random access memory (RAM) M4, etc. are built-in, and based on input data, publicly known
The entire system is controlled using the ROM control method.

Next, the contents of the fixed storage device M1 will be explained using FIG. 3.

In the same figure, the readings of kanji corresponding to each address in the address field M11 are arranged in the reading storage part M12 in the order of ``Aiue'' and ``Natsuki''. A code of o or 1 is stored in the onkun storage unit M13, and if the pronunciation in the pronunciation storage unit M12 is on-yomi, it is stored as “1”, and if it is kun-yomi, it is stored as “0”, and so on. The kanji code storage unit M14 stores codes of kanji corresponding to each reading in the form of a 1-character, 4-digit code. In this embodiment, the fixed storage device M1 is provided with numbers "0000" to "2047" and stores a total of 2048 reading and kanji codes. In general, there are over 2,000 readings and readings for the 996 kanji for learning, which can be covered by 2,048 readings.

Next, the contents of the fixed storage device M2 will be explained using FIG. 4.

In the figure, the address section M21 corresponds to the kanji code in the kanji code storage section M14 in FIG. 3, and one kanji character is stored in the kanji pattern storage section M22.
There are 320 bits (16 x 20 =) to display with 16 x 20 dots, and "1" and "0" data indicate that the dot is lit and "0" is not lit. Based on this data, Kanji 1 is displayed. Display characters.

In this embodiment, the fixed storage device M2 is from "0000" to
It can store up to address "1023" and memorize a total of 1024 kanji patterns.

Note that the learning kanji is 996 characters, and there are 28 characters left over, but information of all "0" is stored in the remainder storage section and processed.

Next, the operation of the kanji learning machine configured as described above will be explained. First, to explain the operation to know the kanji with the reading ``ki'', press the □ key of the kana key group K1 to display ``ki'' on the LCD display LC, then press the kanji key K2, the center arithmetic processing unit
The CPU determines whether "ki" is stored in the pronunciation storage section M12 of the fixed storage device M1. This is done, for example, by starting from the address "0000" in the address field M11 and storing the same reading as the input "key" or by advancing the address one by one, in this case "0330". A coincidence signal is obtained at the address ``0330'', and then the data ``1'' in the read-aloud bit storage unit M13 at the address ``0330'' indicates that the read-aloud mark OKY is ready to be lit. Furthermore, based on the "0463" code in the kanji code storage section M14, the data in the kanji pattern storage section M22 at address "0463" in the fixed storage device M2 is called up, and for example, the kanji "period" for "ki" is displayed on the liquid crystal display LC. do. Also, at this time, when the reading key K3 is pressed, "ki" and the Kun reading mark OKY are displayed on the liquid crystal display LC. At this time, the central processing unit CPU stores the first input address "0330" of "ki" and the pronunciation "ki" in the random access memory M4. When the Kanji key K2 is pressed again,
Add 1 to address 0330 in the address section M11 of the fixed storage device M1, and the reading in the reading storage section M12 is "K".
If so, a kanji character such as "木" is displayed in the same way as above. When you press the reading key K3, "Ki" and Kundoku mark will appear.
KY is displayed. This onkun distinction mark may be displayed at the same time as the kanji. Next, we will explain the operation when learning the kanji ``Kou'', which has multiple onkun readings. The phonetic pronunciation of ``Kou'' is ``Kou'' and ``Ou,'' and the Kun reading is ``Ki.'' First, press □C□C of the input key group K1 to display ``Kou'', and then press the separator key K4.The central processing unit CPU starts from address ``0000'' in the address section M11 of the fixed storage device M1 by an address +1. While performing the reading method storage section M1
2 is "Kou" and the address "0391" in the kanji code storage section M14 is stored in the random access memory M4.

In FIG. 3, there is only one reading for "Kou", but if there are multiple readings, the kanji code for each is memorized. Next, input □ from the kana key K1 and press the delimiter key K4 again. The addresses "0330" to "0346" whose reading is "ki" in the fixed storage device M1 and the corresponding kanji code are called up and the address is read. The kanji code is stored in random access memory M4. With this, the two reading kanji codes of "Kou" and "Ki" are stored in the memory M4, and when the kanji key K2 is subsequently pressed, the control unit CONT of the central processing unit CPU is stored in the random access memory M4. Detects a match to see if there are any characters with the same kanji code for ``Kou'' and ``Ki'', and in this case determines that the kanji code ``0131'' is the same, and then checks the address for which no match was found. and delete the kanji code. Thereafter, the information on the kanji pattern corresponding to the kanji code "0131" is called from the fixed storage device M2, and the kanji character "yellow" is displayed on the liquid crystal display LC. Furthermore, if a plurality of matching signals of kanji codes are received, this fact is notified on the display LC, and when the kanji key K2 is subsequently pressed, the next kanji is displayed. Similarly, if you input "ou", you can get a match with three readings, which reduces the number of kanji codes that can be matched, making the search even faster.
As described above, according to the present invention, even when one kanji has multiple readings and there are many kanji with the same reading as these multiple readings, by inputting two or more readings, the kanji key K2 You can learn the pattern of the desired kanji by operating it once or several times. Furthermore, whether a kanji is read on-yomi or on-yomi can be easily determined by pressing the reading key K3 and lighting on-yomi mark OY and kun-yomi mark KY, which is useful for learners such as elementary and junior high school students.

Note that in this example, the reading of one kanji, that is, the reading of one kanji,
I explained that you can enter multiple kun readings and search for the corresponding kanji with several operations, but you can input the readings of compound words made up of multiple kanji such as genpatsu (nuclear power plant) and genji (atomic) to find the common kanji ``genji''. ” can be easily learned. . This can be done, for example, by storing the pronunciations of idioms such as "genpatsu" and "genshi" in the pronunciation storage unit M12 of the fixed storage device M1, and storing two-character kanji codes for each in the kanji code storage unit M14 in correspondence with this. All you have to do is match the one-character kanji code. Also, the number of idioms is 996 kanji for learning.
Even if we increase the number of idioms that appear above each other by 3, such as ``hara'' in ``nuclear power'', we still need 996 x 3 = 2988, so of course
ROM capacity increases. However, if you enter multiple readings of an idiom to learn common kanji, you may find that a kanji (word) has only one reading, or that you only know one reading when it originally had multiple readings. valid at times.

In addition, you can easily tell whether a kanji is read on-yomi or kun-yomi by pressing the reading key K3 and lighting the on-yomi mark OY and kun-yomi mark KY, which is effective for elementary and junior high school students. effective.
