[Embodiment] A kana-kanji converter which is an embodiment using the kana keyboard input device of the present invention will be described.

FIG. 2 is a front view of a portable size kana-kanji converter 1 having the same size and thickness as a known calculator.

A character display board 2 using a known liquid crystal or the like is provided above the front surface. The character display board 2 includes an upper character display board 2a and
It is divided into an upper character display board 2a and a lower character display board 2b arranged in parallel. The character display boards 2a and 2b are composed of five segments for individually displaying characters.

Below the lower character display board 2b, there is provided a numeric key sequence 4 in which the numbers "1" to "0" are engraved. The numeric key sequence 4 is also an upper numeric key sequence 4a, which is a sequence of five numeric keys on which numbers "1" to "5" are engraved, and "6" to "6" arranged in parallel with the upper numeric key sequence 4a. It is divided into a lower row of numeric keys 4b, which is a row of five numeric keys engraved with the number "0". Upper digit key row 4a-5
Each of the two numeric keys is located directly below each of the five segments of the lower character display panel 2b, and the five numeric keys of the lower numeric key row 4b.
Each of the number keys is provided directly below each of the number keys of the upper row of numeric keys 4a.

Since the character display panel 2 and the numeric key row 4 are arranged at the above-mentioned positions, the characters displayed in the segments of the character display panel 2 and the numeric keys on which the numbers of the numeric key row 4 are engraved can be seen at a glance. It is possible to associate a certain segment with a numeric key stamped with a certain number. For example, the number keys corresponding to the fourth segment from the left side of the upper character display board 2a can be immediately understood as the number keys on which the number "4" of the upper number key row 4a is engraved.

Below the lower row of numeric keys 4b, four horizontal rows and four vertical rows of keys are arranged. Of these, the keys in the two columns from the left,
The keys in the third column from the left and up to the third from the top are the kana key group 6. This kana key group 6 is composed of 11 keys, and is composed of kana from "a" to "wa" which are kana of "a string" of kana syllabary and a kana key engraved with "n". . The fourth key from the left in the third column from the left is "Convert"
The conversion key 8 is engraved with the following characters. The four keys in the rightmost vertical column are the transformation key group 10. In this transformation key group 10, a dakuon key 10a on which a dakuten mark "*" is engraved, a semi-done key 10b on which a semi-dakuon mark "." Is engraved, and a character "consonant" are engraved from the top. It is composed of a consonant sound key 10c and a transformation-unnecessary key 10d engraved with a symbol "*".

All the keys described above are configured by manual operation automatic return contact type (not shown) key switches.

Only 10 character display segments, 10 numeric keys and 16 input keys are arranged on the front surface of the kana-kanji converter 1 including the above-mentioned members. Therefore, even if the Kana-Kanji converter 1 is downsized to be portable, the input key interval of the Kana-Kanji converter 1 has a distance suitable for operation with a fingertip.

Further, an electronic control unit (not shown) is incorporated inside the main body, which is the front and back side of the Kana-Kanji converter 1.

FIG. 3 is an electric system block diagram showing the control system of this embodiment.

The electronic control unit 20 includes a well-known CPU 21, ROM 22,
Input port 24, output port 2 centering on RAM23 etc.
5 and the like are connected to each other by a bus 26 and configured as a logic control circuit.

Connected to the input port 24 are a numeric key sequence 4, keys constituting the kana key group 6 and the transformation key group 10, and a conversion key 8. On the other hand, the output port 25 is connected to each segment constituting the character display board 2.

The processing of this embodiment executed by the control system will be described with reference to FIG.

When power is supplied to the electronic control unit 20, various flags are initialized in S2, and processing such as erasing of memory contents described later is performed, and a standby state where the next processing can be performed is entered. In S4, which of the kana syllabary lines has been selected is determined by depressing one of the kana keys of the kana key group 6. For example, when a kana key in which a kana of "wa" is imprinted (hereinafter referred to as a kana key of "wa") is pressed, it is determined that "wa row" is selected. Unless any of the kana keys of the kana key group 6 is pressed, the above-described pressing operation standby state is continued. On the other hand, if it is determined in S4 that the one line is selected, for example, if it is determined that the kana key of "ha" is pressed and "ha line" is selected, the process proceeds to the next step S6. In S6, all kana included in the line, for example, "ha line" are searched from the Japanese syllabary table of kana stored in a predetermined address of the ROM 22, and the search results "wa", "hi", "fu" are displayed. ","What",
Five kana characters of "ho" are sequentially displayed on the lower character display panel 2b from the left segment. In the next step S8,
It is determined which column of the kana displayed in S6 is selected. This determination is made based on which numeric key of each numeric key of the upper numeric key sequence 4a immediately below each segment of the lower character display board 2b is pressed. For example, when the number key with the number "3" engraved directly below the segment in which "Fu" is displayed (hereinafter referred to as the "3" number key) is pressed, the pseudonym of "C" is selected. It is determined that The standby state of the pressing operation is continued unless any of the numerical keys in the upper numerical key row 4a is pressed. On the other hand, if it is determined in S8 that one column of the above kana is selected, for example, if it is determined that the numeral key of "3" is pressed and the kana of "C column" is selected, the next step is S10. Transition. In S10, the column selected in S8, for example, "fu" which is a pseudonym of "C column" is specified.
In the next step S12, it is determined whether or not the kana "fu" of one character thus specified is transformed. This change judgment is made based on which change key of the change key group 10 is pressed. When the voiced sound key 10a is pressed, it is determined that the transformation to voiced sound is selected, and the process proceeds to S14. When the semi-voiced sound key 10b is pressed, it is determined that the transformation to the semi-voiced sound is selected, and the process proceeds to S16. When the audible sound key 10c is pressed, it is determined that the change to the audible sound is selected, and the process proceeds to S18. When the transformation unnecessary key 10d is pressed, it is determined that the transformation unnecessary is selected, and the process proceeds to S20. In S14, the kana "fu" specified in S10 is transformed into "bu". S
In 16, the "fu" specified in S10 is transformed into "pu". For example, if "yo" is specified in S10, S
In 18, this "yo" is transformed into "yo". In S20, S
Do not change "Fu" specified in 10. Next step S
In step 22, the steps S14, S16, S18 and S
Kana of one character is decided based on the transformation result of 20.
The characters are sequentially displayed on the upper character display board 2a in the leftward order. At the same time, the kana displayed on the lower character display board 2b is erased. In the next step S24, the one-character kana determined in step S22 is written in the memory allocated to the predetermined address of the RAM 23. In S26, it is determined which of the new kana syllabary lines has been selected by pressing one of the kana keys of the kana key group 6 or which conversion has been selected by pressing the conversion key 8. . If it is determined that a new row has been selected, the processing from S6 to S26 is repeated. On the other hand, if it is determined that the conversion is selected, the process proceeds to the next step. In step S28, the kanji written in the memory in step S24 is read in the ROM 22
Is searched from a kanji map or the like stored in advance at a predetermined address, the search result is displayed on the character display panel 2 in preference to the kana which is determined and displayed in S22, and the process proceeds to the next step. In step S30, it is determined which of the kanji displayed in S28 has been selected.
This judgment is made by determining which number of each numeric key which constitutes the upper numeric key row 4a or the lower numeric key row 4b having the arrangement corresponding to each segment constituting the upper character display panel 2a and the lower character display panel 2b arranged in parallel. This is done depending on whether the key is pressed. For example, when the numeral key with the number "6" in the lower numeral key string 4b is pressed, it is determined that the Chinese character displayed in the first segment from the left of the lower character display board 2b has been selected. Unless any of the numeric keys of the numeric key sequence 4 is pressed, the standby state for the pressing operation is continued. On the other hand, if it is determined in S30 that one of the Chinese characters has been selected, the process proceeds to the next step S32. In S32, the Chinese characters selected in S30 are displayed on the upper character display board 2a in the leftward direction, and at the same time, the Chinese characters other than the Chinese characters displayed in S28 are erased. When the kanji selected in this way is displayed, the process proceeds to the initial processing of S2, and a new kana input is accepted. Here, the correspondence between the present embodiment and the constituent elements of the present invention will be clarified. That is, the kana key group 6 of the present embodiment is the row selection key of the present invention, the upper numeric key row 4a is the column selection means, the transformation key group 10 is the transformation selection means, and the character display panel 2 is the kana display means. Equivalent to. Further, the electronic control device 20 corresponds to a display control means including a line display control means, a kana identification means, a kana determination means, and a kana display control means. Further, S6 of FIG. 4 corresponds to the processing of the line display control means, S10 of the same figure corresponds to the processing of the kana specifying means, and S12 to S22 of the same figure correspond to the processing of the kana determining means. Although the processing of the kana display control means is not shown, the kana of one character determined in S22 of FIG. 4 is sequentially displayed on the upper character display board 2a in the left-hand direction and simultaneously displayed on the lower character display board 2b. The process of erasing the kana that was being performed corresponds to this.

As described above, the kana-to-kanji converter provided with the kana keyboard input device according to the present invention reduces the number of input keys required to enter a kana even though its main body is small, so each input The key spacing is appropriate, and you can input a kana by pressing the input keys with your fingertips without touching the adjacent input keys. Further, since the kana key engraved with the kana of the Japanese kana syllabary "A line" is used, it can be widely and generally used without a sense of discomfort, unlike the Roman alphabet input key.

Although the kana-kanji converter in which the character display board and the numeric key string are each divided into two stages has been described, the present invention is not limited to this embodiment, and various modes are possible without departing from the gist of the present invention. You may implement.

For example, as shown in FIG. 5, it may be a kana-kanji conversion machine in which a character display panel and a numeric key string are arranged in one row respectively, or the kana and kanji characters can be input by sequentially inputting the kana into the microcomputer. The kana-kanji conversion which is mixed may be executed by this microcomputer, and the kana input keyboard device of the present invention may be used as an interface for kana input to the microcomputer.

[Effects of the Invention] As described above, the present invention can reduce the number of input keys for inputting a kana and provide a portable kana keyboard input device having a key interval that can be operated with a fingertip. did. Further, when inputting an arbitrary kana, the worker first determines which line the kana belongs to by thinking and presses the corresponding line selection key, and as a result,
The kana included in the selected line is displayed, and the kana to be input is visually identified and specified from the displayed kana. In this way, since Kana is specified by stepwise operation using both thinking and vision, even a beginner who has no experience operating the keyboard does not need much time to search for a character to input, and it is easy and You can enter it quickly.

Also, the kana of the Japanese syllabary is displayed as a single character, including dakuon, semi-voiced sound, and consonant.
The aesthetics of the display can be obtained.

Further, since the kana is displayed on the row selection key, even a person who has no experience operating the keyboard does not need much time to search for a character to be input, and can input easily and quickly.
