Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device with a learning function in which an electronic Japanese-Chinese dictionary is provided with a Kanji reading learning function.

An electronic Japanese-Kanji dictionary is an electronic device that inputs the reading signal of a kanji using the kana character key, retrieves the kanji corresponding to the kanji reading from memory, and displays the pattern of the kanji on the display. To give an example, the function is to retrieve an unspecified kanji from memory using the kanji question key and display it on the display, and when the learner does not understand the kanji or is unsure of the kanji, the student can press the pronunciation display key. This means a function that displays the correct reading of the kanji when pressed.

Conventionally, there has been no electronic device with a learning function that has the function of an electronic Japanese-Chinese dictionary and the function of learning how to read kanji. Furthermore, if an electronic device were to have these two functions, the circuit would be complicated, the device would be large, and the price would be high.

In view of the above-mentioned points, the present invention uses a dot matrix to display kanji or kana, performs the dictionary function and the learning function using a substantially common circuit, is small and inexpensive, and has a Japanese-kanji dictionary and a kanji dictionary. An object of the present invention is to provide an electronic device with a learning function that has the function of a reading learning machine.

Hereinafter, the present invention will be explained in detail based on the drawings.
FIG. 1 shows an embodiment of an electronic device with a learning function according to the present invention. Here, the CPU is a central processing unit, and the signals 11 to 11 are input based on the pressing of various input keys K1 to K6.
16, and outputs various signals via signal lines X1 to X4. ROM1 and ROM2 are fixed storage devices that store information about kanji, and OUT is an output device, which includes a decoder DEC, a symbol mark M1 that indicates an incorrect answer, a correct answer mark M2, a display section DIS that displays kanji and kana, and a printing device. PRT
have. R1 is a random number generator that generates random numbers in response to pressing the key K1, and AC is a random number generator R.
After receiving the random number output signal from 1, the fixed storage device
This is an address counter that specifies the address of ROM1. IB is a kana memory that encodes and stores kana etc. in response to pressing the key K3.
By pressing 1, K2, K4, K5, or K6, the contents are erased. D1 outputs the delay signal DSI corresponding to the press of the key K1 to the AND gates G2 and G when a predetermined period of time has elapsed after the press of the key K1.
3. The first delay circuit that supplies G5, RAM1, is a fixed storage device at the timing of the aforementioned delay signal.
The ROM1 is a random access memory in which pseudonym information is stored via an AND gate G2. Similarly, the RAM2 is a random access memory in which the kanji information stored in the fixed storage device ROM1 is stored via an AND gate G3 at the timing of the delay signal DS1. D2 is the second delay circuit, which connects the signal line X from the central processing unit CPU.
Kana information that passes through the AND gate G6 at the timing of the signal with the logical value "1" outputted through the gate G6;
That is, it is a second delay circuit that displays the pronunciation kana information in the random access memory RAM1 on the display section DIS a little later than the above-mentioned timing.

Next, the fixed storage device ROM1 shown in the first diagram, ROM
2 will be explained in detail.

The fixed storage device ROM1 is made up of three memories: memory ROM1A, memory ROM1B, and memory ROM1C. Memory ROM1A stores the reading kana address of the kanji, and memory ROM1B stores the reading kana of the kanji corresponding to this address. is encoded and stored in the memory ROM 1C, and a number assigned to each kanji character corresponding to the above-mentioned address and corresponding to its reading kana is encoded and stored in the memory ROM 1C. In the other fixed storage device ROM2, there are two memories.
Has ROM2A and ROM2B, memory ROM
2A stores the address of the kanji, and the memory ROM2B
Kanji pattern information corresponding to the address of the memory ROM2A is coded and stored in the memory ROM2A. In the example below, the fixed storage devices ROM1 and ROM2 are
It is assumed that information regarding 996 educational kanji characters is stored in .

Figure 2A shows an example of the fixed storage device ROM1, where the address of the memory ROM1A is originally a coded number, but to make it easier to understand, it is a four-digit decimal number. It is shown. memory
The kana characters stored in ROM1B are usually expressed in 6 bits (64 ways), including lowercase letters, but in the figure they are shown in kana characters. Furthermore, the numbers for Kanji characters in the memory ROM 1C, which were originally expressed as 10 binary bits (=1024), are shown as three-digit decimal numbers in the figure. The numbers in the memory ROM2A of the fixed storage device ROM2 shown in FIG. . That is, the pronunciation kana stored at address i in the memory ROM1A and the kanji character stored at address i in ROM2A have no relation to each other.

Here, the reason for dividing the fixed storage devices ROM1 and ROM2 will be described. For example, educational kanji are
It is said that there are 996 characters, but the readings of each of these characters, including the onkun, are over 2000. On the other hand, kanji patterns are usually represented by a dot matrix of 20 rows x 20 columns = 400 dots. fixed storage
The memory ROM1B of ROM1 stores 2000 different pronunciations for 996 kanji, and the kanji patterns corresponding to each of these are stored in the memory ROM1.
If each is stored in C, the memory
ROM1C requires 400×2000=800000 bits of memory. Therefore, first, instead of a kanji pattern, a specific number is attached to each kanji, and if that number is stored in the memory ROM1C as kanji information, 996
10 bits (2 ¹⁰ = 1024) are sufficient for each of the 2000 reading kana. Next, the memory ROM2 of the fixed storage device ROM2
At A, take the address in the order of the kanji number as shown in Figure 2 B,
Even if a kanji has multiple readings, by memorizing only one display pattern for each kanji, the number of memory bits for the kanji pattern can be reduced.
400×996 (ROM2B section) + 10×2000 (ROM1C section)
= 418,400 bits, which is approximately half the number of bits when storing kanji patterns in correspondence with the pronunciations stored in the memory ROM 1B.

The present invention will now be described in further detail with reference to FIG. In Figure 1, K1 is the "Kanji question key"
When a signal from key K1 is input to random number generator R1, a random number is input to address counter AC. The address counter AC selects a 4-digit random number from a predetermined address (numbers over 1999 are not used).
Specify the address of 1A. A signal I4 of the reading kana of the memory ROM1B and a signal I5 of the kanji code of the memory ROM1C corresponding to the designated address are input to the central processing unit CPU. Signal I4
is also supplied to AND gate G1 and AND gate G2, but AND gate G1 is opened only by pressing key K2, and signal I4 supplied to AND gate G2 is a delayed signal from delay circuit D1.
Random access memory at DS1 timing
Supplied to RAM1. Therefore, the memory RAM1 stores the pronunciation kana corresponding to the address selected by pressing the key K1 from among the pronunciation kana stored in the memory ROM1B. On the other hand, the signal I5 is supplied to AND gates G3, G4, and G5, respectively, and the signal I5 is supplied to the random access memory RAM2 at the timing of the delay signal DS1 supplied to the AND gate G3. Therefore, the memory RAM2 stores the Kanji code corresponding to the address selected by pressing the key K1 from among the Kanji codes stored in the memory ROM1C. Also, and gate G5
The signal I5 supplied to the memory ROM2A of the fixed storage device ROM2 is also specified by passing through the AND gate G5 at the timing of the delayed signal DS1. The kanji pattern code in the memory ROM 2B corresponding to the designated address is sent to the output device OUT via the signal line Y1, decoded by the decoder DEC, and the kanji character corresponding to the designated address is displayed on the display section DIS. In this way, when the kanji question key K1 is pressed, an unspecified kanji appears on the display section DIS.
The questioner can learn how to read the kanji by himself.

K2 is the "pronunciation kana display key", and when the pronunciation display key K2 is pressed after the kanji question key K1 is pressed, the pronunciation kana output I from the memory ROM1B is
4 is output from the key K2, so it is sent to the output device OUT through the AND gate G1, and is displayed below the dotted line on the display section DIS via the decoder DEC. That is, the reading kana of the kanji selected by pressing the key K1 is displayed.

K3 is a "kana input key" such as □A~□N, 〓, □, etc., and is arranged on the keyboard KB. When the kana input key K3 is pressed, a signal such as a kana corresponding to this press is supplied to the kana memory IB.

K4 is a "pronunciation kana input completion key" that is pressed after pressing the kanji question key K1, then the pronunciation input key K3, and when the pronunciation input is completed.In response to the press of the key K4, the signal I3 is central processing unit
Supplied to the CPU.

K5 is a ``kanji search key'' which, after pressing the kana input key K3, outputs a signal 12 for searching for a kanji corresponding to the kana by pressing the key K3, or a kanji corresponding to the pronunciation starting with the kana.
For details on the operation after pressing the kanji search key K5, please refer to the 4th section.
This will be described later with reference to the drawings.

K6 is a "kana erasure key" for erasing the kana entered into the kana memory section IB by pressing the kana input key K3.

The kana memory unit IB stores each signal of the kana input key K3 in binary code, and each time the key K3 is pressed, the binary code information 11 corresponding to each kana character is sent to the output device OUT and the central processing unit CPU.
Output to. The information in the pseudonym memory section IB is also erased by the output of the OR gate OR1 in response to the signals generated by pressing each of the keys K1, K2, K4, and K5. Here, the kana corresponding to the press of the kana input key K3 is converted into a binary code by the kana memory unit IB. It is preferable to make the encoding method the same as that of .

Next, the output signal line X from the central processing unit CPU
1, X2, X3, and X4 will be described.

"Signal line X1": This is a signal line for inputting any kana and displaying the corresponding kanji on the display section DIS. That is, after pressing the kana input key K3, the kana is input to the central processing unit CPU as a coded signal 11, and then when the kanji search key K5 is pressed and the signal I2 is input to the central processing unit CPU, the signal 11 is input to the central processing unit CPU. When the input kana code is received in the memory ROM1B, a logical value "1" is output from the signal line X1 (see the flow on the left side of FIG. 3). In this case, the kanji code in the memory ROM1C is supplied to the fixed storage device ROM2 via the AND gate G4 and the OR gate OR2.
Select address A. that selected memory
Kanji pattern information stored in the memory ROM2B corresponding to the address of the ROM2A is output to the output device OUT via the signal line Y1.

"Signal line X2":: When you enter any kana,
If there is no kanji corresponding to this kana, or if an incorrect pronunciation of the kanji is input when learning to read the kanji displayed on the display unit DIS, the symbol mark M1 will be lit on the output device OUT.
In the latter case, it is a signal line that sends a signal to display the correct reading kana on the display section DIS. That is, when the above-mentioned kanji search signal I2 is input to the central processing unit CPU, (i) the kana code input by the signal 11 is not stored in the memory ROM1B, and (ii) the kanji question key K1 After pressing , input a pronunciation different from the pronunciation of the question kanji (that is, an incorrect one) into the central processing unit CPU using the key K3, and then press the pronunciation input completion key K4, the signal line X2 A logic value "1" is output from the output. In the case of (ii) above, the symbol mark M1 of "not applicable (incorrect answer)" is displayed or printed on the signal that is directly input to the output device OUT among the signals "1" of X2. Also, since the signal “1” of X2 is applied to the AND gate G6,
The code of the reading kana (correct answer) of the kanji on the question stored in the random access memory RAM1 passes through the AND gate G6, is delayed for a certain period of time by the second delay circuit D2, and is input to the output device OUT, and the correct answer is displayed or printed. be done.

"Signal line X3": When the problem is solved correctly,
This is a signal line for inputting a specific signal to the output device OUT in order to light up or print the symbol mark M2.

"Signal line X4": This is a signal line that sends a signal to change the address of the address counter AC one by one when the kanji search key K5 is pressed and when the pronunciation kana completion key K4 is pressed. When the signal I2 or I3 is input to the central processing unit CPU by pressing the key K5 or K4, respectively, the kana input key K is input in the central processing unit CPU.
A comparison is made between the kana code signal 11 corresponding to the pressing of 3 and the reading kana code signal I4 from the memory ROM1B. If both signals do not match, the address counter AC is activated by the signal from signal line X4.
The address of the memory ROM is sequentially incremented by 1
The address of 1A is changed and comparisons between signals I1 and I4 are performed sequentially.

When the signal I2 is input by pressing the kanji search key K5, the signal I2 is input based on FIG. The operation will be described later.

Here, the functions of the signal lines X2, X3, and X4 will be explained in detail.

For example, when the key K1 is pressed and "Mei → Ming" is selected at a certain address in ROM1A, and "Ming" is displayed on the display section DIS, the user further inputs "Min" using the kana input key K3. Assume that the user then presses the completion key K4. In this case, the address of the fixed storage device ROM1 is sequentially changed by the instruction signal from the signal line X4, the kana index of "Min" is searched for in the memory ROM1B, and the memory ROM
If "Min" is stored in 1B, the memory ROM is stored corresponding to the kana index of "Min".
By pressing the signal I5 corresponding to the kanji code stored in 1C and the question key K1,
This will be compared with the signal I6 corresponding to the Kanji code stored in the ROM2. Therefore,
When "Ming" is displayed, the reading is correct, either "Mei" or "Min", and the central processing unit CPU outputs "1" to the signal line X3 due to I5 = I6 matching, and lights up the correct answer symbol mark M2. or display. When input other than this, for example, ``Men'' is input, there is no kanji code for ``Ming'' in the memory ROM1C at the address corresponding to the kana index of ``Men'', so this causes a logical value to be sent to the signal line X2. Output “1” and as described in the “Signal line X2” section,
Display or print the incorrect answer symbol mark M1. After that, the kana index of the correct answer "May" stored in the memory RAM1 is outputted to the output device via the AND gate G6 and the second delay circuit D2.
It is sent to OUT, decoded by the decoder DEC, and "May" is displayed at the bottom of the display.

Here, further explanation will be added with reference to the fixed storage devices ROM1 and ROM2 shown in FIG. 2A and FIG. 2B. In the fixed storage device ROM1,
The kana characters "Akarui" and "Mei" are stored in the memory ROM1B corresponding to addresses 0002 and 1720 of the memory ROM1A, and the kanji code "80" is stored in the memory ROM1C corresponding to these addresses. has been done. Therefore, it can be seen that the kanji corresponding to "Akarui" and "Mei" are the same kanji. Also, in order to make the explanation easier to understand, address 1999 only contains the last code "N", so when you search and advance through the addresses, when the code "N" is detected,
A specific signal is sent from the signal line X2 to the output device CUT. Regarding this signal, it is already "signal line X2"
It is mentioned in the section.

FIG. 3 is a flow chart for explaining the operation when the signal I2 corresponding to the depression of the kanji search key K5 is input during the work performed inside the central processing unit CPU. In other words, in this flowchart, for example, when you want to know the kanji that corresponds to ``kan'', first input ``kan'' using the key K3, then press the search key K5, and search for 1 or more characters corresponding to ``kan''. It is designed to display the kanji of .

FIG. 3 will be explained below with reference to FIG. 1. When the kanji search key K5 is pressed, the first step is step S.
1, the signal I2 is the first after pressing the kana input key K3.
It is determined whether or not the occurrence occurred due to the first press of the key K5. If it is the result of the first press of the key K5, the process jumps to step S2 and the address counter AC is set to the initial address (address "0"). ). Next, proceed to step S3, and proceed to step S3.
At this point, the code signal I1 input using the kana input key K3 is compared with the pronunciation kana code signal I4 at address "0" in the ROM 1A. Here, the signal 〓
indicates that the comparison between the signals I1 and I4 described above is partially performed at the beginning of the signals. For example, press the kana input key K3,
If you press the search key K5 after inputting "Kan" as signal I1 to the central processing unit CPU, you will find not only "Kan" among the pronunciations stored in the memory ROM1B, but also pronunciations starting with "Kan" such as "Kangae". It also searches for. In an actual circuit, a coincidence circuit detects a match between a binary code portion of the code of the signal I4 corresponding to the input number of digits and a binary code of the signal I1 corresponding to the same number of digits. In step S3, as described above, if there is a kana index starting with the same kana as the entered kana, the process advances to step S4.
A logic value "1" is output to the signal line X1. Thereafter, as already described in the section of "signal line X1", the kanji pattern corresponding to the kanji pattern information stored in the memory ROM2B is displayed on the display device DIS. If there is a mismatch in step S3, it is determined in step S6 whether or not it is the final address using the "n" code, and if it is the final address, a logic value "1" is output to the signal line X2, and the output device
The OUT symbol mark M1 is lit or printed to notify that the kanji starting with the kanji "kan" is not stored. If it is not the final address, the process jumps to step S5 and increments the address by one. Therefore, by performing a kanji search (using key K5) after inputting "kan", steps S3, S6, and S5 are entered.
In the example shown in FIG. 2A, the index of "Kangae" is found at the 82nd time, and the process goes to step S4, where a signal "1" is output to the signal line X1. Next, when the kanji search key K5 is pressed again, in step S1, since the pressing of the key K5 is not the next key pressing of the kana input key K3, the process immediately jumps to step S5, and the process immediately jumps to step S5.
Advance the address of ROM1A by one. In the example shown in FIG. 2A, "Kanjiru" at address 83 is searched for in step S3, and "1" is output to the signal line X1 in step S4 to display the display DIS.
The kanji corresponding to ``kanjiru'' is displayed. Furthermore, when the kanji search key K5 is pressed, since there are no more reading indexes starting with "kan", the process finally reaches step S7, and the signal line X2 is pressed.
A logical value "1" is output to the output device OUT, and the symbol mark M1 of the output device OUT indicates that the kanji starting with "kan" is no longer stored. Note that since each cycle of these processes usually takes 1/1000 seconds or less, the time required to reach the final step is extremely short.

Incidentally, when "1" is output to the signal line X1 in step S4, the kanji pattern is displayed on the display section DIS as described above. Therefore, this
The I2 routine can be used for Japanese-Chinese dictionaries and Japanese-Chinese learning.

Figure 4 shows that while a kanji question is being displayed by pressing the kanji question key K1, the learner inputs a reading kana using the kana input key K3, and then presses the reading kana input completion key K4.
This is a flowchart for explaining the internal operation of the central processing unit CPU when is pressed.
Here, S10 to S17 indicate each step of the program. The explanation will be given below with reference to FIG.

First, in step S10, the input kana code signal 11 is compared with the pronunciation kana code signal I4 of the memory ROM1B which has already been selected by pressing the kanji question key K1. If both codes match, a logic value "1" is set to the signal line X3 in step S14.
is output, and the symbol mark M2 on the output device OUT is lit to indicate that the answer is correct. Here, I1=I4 means that the codes of signals I1 and I4 match in all bits.

If in step S10 the code signal I1
If and I4 do not match, step S11
In step S12, the address counter AC is set to the initial address (address "0").
Again input kana code I1 and new address, that is, pronunciation kana code signal I4 corresponding to address 0000.
If they match, in step S13, the kanji code signal I5 corresponding to the new address, that is, address 0000, matches the kanji code signal I6 selected by pressing the key K1 and already written in the memory RAM2. If they match, "1" is output to the signal line Go forward, step S
If it is recognized in step S16 that it is not the final address, the process returns to step S12. When it is determined in step S16 that it is the final address, the process jumps to step S17 and outputs "1" to the signal line X2. This routine is to obtain a pronunciation for the same kanji that is different from the pronunciation corresponding to the address selected for the kanji on the test. In order to exclude cases where the kanji is different from the displayed kanji, a match between the kanji codes is confirmed in step S13.

For example, the random number generator R1 by pressing the key K1
When address counter AC specifies address 0002 of memory ROM1A based on the output signal of
"Bright" stored at address 0002 of the memory ROM1C is displayed on the DIS. When the learner sees the kanji ``Ming'' and uses the kana input key K3 to input the signal I1 corresponding to ``Akarui'' as the answer reading kana into the central processing unit CPU,
The signal I4 corresponding to "Akarui" input from the memory ROM1B to the central processing unit CPU matches the signal I1. Therefore, the process advances to step S14 and "1" is output to the signal line X3. As a result, a symbol mark M2 indicating a correct answer is displayed or printed on the output device OUT.

Press the key K3 and send "May" to the central processing unit.
When input to the CPU, in step S10, the signal I4 corresponding to "Akarui" and the signal I1 corresponding to "May" do not match, so the process jumps to step S11. In step S11, the address counter AC is set to "0", and then steps S12, S15, and S16 are used as a loop to sequentially search the fixed storage device ROM1 from address "0" until "May" is stored. Search for the address of the memory ROM1B that is being stored. Then, when the address "May" (in ROM 1B) is reached, I1=I4. However, if the kanji code in the ROM1C corresponding to ``mei'' is for ``name'', the kanji identification information is compared in step S13, that is, it is determined that I5≠I6, and therefore steps S13 to S15 are performed.
, the search continued, and it corresponded to "May".
When the kanji code in ROM1C is for "Ming", I5=I6, and the correct answer is shown in step S14.

Furthermore, if the kana entered using key K3 is incorrect (for example, when "men" was entered in the previous example), the process proceeds to step S17 after searching up to the final address.
Outputs "1" to the signal line X2. As a result, as described above, the random access memory RAM 1 corresponds to the address selected by pressing the key K1 via the AND gate G6 and the second delay circuit D2.
Displays or prints the reading kana stored in , that is, one of the correct answers.

From the above, this I3 routine is used for learning the Kanwa dictionary and Kanwa.

Note that in Figures 3 and 4, processing is finished by determining the end code, but the memory
Since the pronunciation kana indexes in ROM1B are arranged in alphabetical order like a dictionary, if the process is terminated by determining that the index code I4 in the memory ROM1B has become larger than the kana input code I1 from the key K3, Average processing time is reduced. That is, the encoding of the kana in the kana memory 1B and the encoding of the kana in the memory ROM 1B are performed using the same method, and furthermore,
The binary code may be made larger as the number advances to "n".

In the embodiment described above, a kanji character is attached to a single character, but for compound words with two or more kanji characters, multiple memories ROM1C as the kanji code part of the fixed storage device ROM1 can be provided. Solvable.

From the above, the electronic device with a learning function of the present invention can be used as a Chinese-Japanese dictionary, as a learning machine for learning how to read Kanji, as a Japanese-Chinese dictionary, or as a learning machine for searching for Kanji from Kana. It has the advantage of being uncomplicated and inexpensive.
