Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic kanji processing device equipped with an idiom search function.

An electronic kanji learning machine is a machine that inputs the reading of a kanji using the kana character key, retrieves the kanji that corresponds to the reading from the memory, and displays the pattern of the kanji on the display. means a function of searching the memory for a phrase formed using the displayed kanji and displaying the kanji pattern of the phrase on the display section.

Conventionally, there is no electronic kanji processing device that has a compound word search function.

Furthermore, when attempting to provide these two functions in a single electronic device, the circuitry becomes complex, the device becomes large, and the price becomes high.

In view of the above-mentioned points, the present invention displays kanji using a dot matrix, uses a circuit that is almost common to the dictionary function and the phrase search function, is small and inexpensive, and is equipped with a Japanese-Chinese dictionary and the phrase search function. The purpose of the present invention is to provide an electronic kanji processing device.

An embodiment of the present invention will be described in detail below based on the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, in which a key input device includes a KB, a central processing unit CPU, a fixed storage device ROM1 for storing kanji information, and a ROM.
2. Memory RAM1 and RAM2 for temporarily storing address information, display device Dsp, input line I to CPU
1, I2, I3, and an output line O1 from CPU.

As shown in FIG. 2, the key input device KB has a 50-on-kana key, a kana-kanji conversion key "Kanji", and an idiom search key "idiom".

The fixed storage device ROM1 consists of two memories, memory ROM1A and memory ROM1B.
In the ROM 1A, the pronunciations of kanji characters are stored as codes for each address, and in the memory ROM 1B, two numbers assigned to each kanji character corresponding to the pronunciations are stored in codes.

Another fixed storage device ROM2 stores fixed-length Kanji patterns for dot matrix display at each address. Each address corresponds to a Kanji number in the memory ROM1B.

FIG. 3 shows details of the fixed storage devices ROM1 and ROM2.

Now, when key signals are input from the key input device KB through the signal line I1 in the order of "A", "Me", and "Kanji", the central processing unit CPU searches for "Ame" by kana on the memory ROM1A, and stores it in the ROM1A. The above address is obtained, and two kanji numbers stored in the memory ROM 1B corresponding to each kana are obtained. At this time
The address information on ROM1 is stored in memory RAM1. Also, the memory RAM2 is cleared.

The kanji number obtained here indicates the address on the fixed storage device ROM2 that stores the kanji pattern as described above, so the central processing unit CPU obtains the two kanji patterns corresponding to the kana string "ame". and sends it to the display device DSP through the output line O1.

In Figure 3A, the kana string "ame" exists at address 0049 and its kanji number is 152000, so
At this point, the pattern 011100101...0 at address 152 and the pattern 000...0 which means a blank at address 000 are sent by the central processing unit CPU to the display device DSP, and the kanji character "rain" is displayed as shown in Figure 2. be done. Also, address code 0049 is stored in the memory RAM1.

Next, when the key signal "idiom" is input from the key input device KB through the signal line I1, the central processing unit
The CPU searches the fixed storage device ROM1 for phrases related to the displayed kanji, and
Kanji patterns are obtained from ROM2 and displayed on the display DSP.

The procedure is as shown in the flowchart of FIG.

First, the content "address a" of RAM1 is compared with the content "address b" of RAM2. RAM1 stores address a on the fixed storage device ROM1 where the kana character string "ame" is stored, and RAM2 stores address b for searching for phrases, but as mentioned above, RAM2 is used for kana-kanji conversion. Since it is cleared at the time and the contents become 〇〇〇〇, it increases by 1 each time the process returns to . This means that the phrase search machine starts from address 〇〇〇〇 on ROM1 and proceeds sequentially to the larger address.

Comparing a and b means checking whether the address currently being searched is the same kanji that is displayed, so if they are equal, jump to b and immediately add 1 to b.
is added and then compared with the maximum address 1999 of ROM1, and if the content of b is less than that, return to step.

If a and b are not equal, address a on ROM1
The first Kanji address l(a) corresponding to the same address b is compared with the first Kanji number l(b) corresponding to the same address b.
If they are equal, a compound word containing a kanji with the same number as the kanji being displayed on the display DSP is obtained, so the process jumps, obtains a kanji pattern from the fixed storage device ROM2, displays it on the display DSP, and adds 1 to b. The process ends.

If they are not equal, the above l(a) is compared with the second kanji number m(b) corresponding to address b on the ROM 1, and if they are equal, the process jumps and the display process is performed.

If not equal return to RAM2 via
The above-mentioned process is repeated until the content b becomes larger than the maximum address.

If b becomes larger than the maximum address, b is set to 0 and the process ends.

The content a of the memory RAM 1 remains unchanged during this process, and the content b of the memory RAM 2 is stored in the fixed storage device ROM by continuous input of the "idiom" key signal, since the address next to the phrase being displayed is the first address 0. The above idioms are displayed one after another on the display device DSP in ascending order of address.

For example, the key signal from the key input device KB is “A”.
When "me", "kanji", "idiom", and "idiom" are input in this order, the display changes in the order of A, B, and C in FIG. 5 in accordance with "kanji", "idiom", and "idiom".

In order to simplify the explanation, the idioms are limited to two kanji characters here, but if the memory ROM 1B is expanded, the idioms can be made up of three or more kanji characters, and can be used for a wider range of purposes.

As explained above, according to the present invention, it is possible to provide an electronic kanji processing device which is small and inexpensive and is equipped with a Japanese-kanji dictionary and an idiom search function by simply passing through a circuit that is simpler than the conventional technology.
