Description

Technical Field

[0001] The present invention relates to a technology for inputting Japanese, and more specifically, to a Japanese character input device that enables quick and accurate input of Japanese using a minimum number of combination keys when inputting Japanese through an input device such as a computer keyboard or a game keyboard, and a terminal device equipped with the same.

Background Art

[0002] Hangul is known as the most scientific language that expresses sounds consisting of an initial sound, a medial sound, and a final sound. In recent years, a keyboard has been developed as a character input device, but the order of the keys arranged on this keyboard is currently used as it is for the English keyboard of a computer. While such a keyboard was introduced in Korea, a keyboard with consonants arranged on the left side and vowels arranged on the right side was developed depending on the frequency of use of Hangul and input convenience. Recently, with the spread of smartphones, various types of simplified screen input devices have become popular, and research and development are actively underway.

[0003] From a global perspective, since the character input methods of each country may differ depending on the unique traditional characters, languages, and living habits, it is not easy to implement a unified character input device. However, by using the scientific nature and structural universality of Hangul, unity and convenience can be imparted to foreign language character input. For example, by applying Hangul to a Japanese input device, Japanese can be input more conveniently.

[0004] Currently, the input device of a smartphone, which is widely used as a Japanese character input device, has a structure of 4 rows × 5 columns as shown in FIG. 1. Using this input device, when trying to input " TIFF2026076082000002.tif961", press the " When trying to input TIFF2026076082000003.tif814, since there is no "o" key, you press the "a" key five times. That is, the word order of Japanese vowels is "a, i, u, e, o", but the typical initial vowel is Only TIFF2026076082000004.tif914 is set as the key, and the remaining vowels are displayed by repeatedly pressing this representative key. When trying to input "po" with this input device, first press "ho" To display TIFF2026076082000005.tif813, press the "ha" key five times, then find and press the "." key, and then press "ta". Press the TIFF2026076082000006.tif714 key three times and type "tsu". The file must be converted to TIFF2026076082000007.tif914, and then the key to convert it to the geminate consonant "っ" must be pressed. This requires a total of 11 keystrokes.

[0005] Therefore, current Japanese input devices are inconvenient not only for Japanese people but also for foreigners, as typing takes time and requires pressing the main key multiple times, which increases the likelihood of typos.

[0006] To alleviate the inconvenience of such Japanese character input, a patent has been disclosed for a method of inputting Japanese characters by separating them into consonant and vowel parts.

[0007] Korean Patent Publication No. 10-1426643 (registered July 29, 2014) discloses an input device, as shown in Figure 2, in which a consonant key group 11' consisting of alphabet consonant keys such as "K", "H", "N", "T", "S", and "W", and a vowel key group 12' consisting of alphabet vowel keys such as "A", "I", "U", "E", "O", and "Y" are arranged, and central input keys 11a' and 12a' are arranged in the center, with numerous peripheral input keys 11b' and 12b' arranged around the central input keys 11a' and 12a'. When the central input key 11a' is pressed, the new consonant "M", "R", "P", "T", and "V" are displayed on the peripheral input keys 11b'. 11c' and 12c' are peripheral keys for changing keys. However, this patent has the problem that the display of consonants is cumbersome.

[0008] Korean Published Patent No. 10-2014-0050796 discloses a keypad arrangement, as shown in Figure 3, in which keys displaying vowels are arranged on the left side of the keyboard, keys displaying consonants are arranged in the remaining part, and voiced and geminate consonants are indicated by repeatedly pressing the consonant keys. However, because this patent primarily focuses on keyboard simplicity, it does not include the semi-vowel "ya" which is frequently used in Japanese. TIFF2026076082000008.tif913, "Yu" TIFF2026076082000009.tif813, "Yo" TIFF2026076082000010.tif813, "wa" TIFF2026076082000011.tif812, and "wo" One drawback is that inputting TIFF2026076082000012.tif812 is inconvenient.

[0009] Furthermore, the aforementioned patent uses a Roman alphabet keyboard as an example of an input device, and suffers from a lack of scalability and universality, meaning it cannot be applied to foreigners unfamiliar with Romanization, nor to Japanese or Koreans who are familiar with their own unique scripts.

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that when assigning reference numerals to the components in each drawing, the same reference numerals are used whenever possible for the same component, even if they are shown in other drawings. Furthermore, when describing the present invention, if a specific explanation of a known configuration or function is deemed to be obvious to a person skilled in the art or to be likely to obscure the gist of the present invention, such detailed explanation will be omitted.

[0026] Figure 4 shows an embodiment of the Japanese input device of the present invention, and Figures 5 and 6 show other embodiments of the sequential key section.

[0027] Referring to Figure 4, the Japanese input device 10 according to an embodiment of the present invention includes a series representative key section 11, a sequence key section 12, and other key sections 13.

[0028] The Japanese input device according to the present invention, configured in this manner, will be described below with reference to Figures 5 and 6.

[0029] The series representative key section 11 has 14 keys that represent each series of Japanese characters, namely the keys a, ka, ga, sa, za, ta, da, na, ha, ba, pa, ma, ra, and ya. The keys that make up each series are as follows:

[0030] Series: A, I, U, E, O

[0031] <ka> series: ka, ki, ku, ke, ko

[0032] <ga> series: ga, gi, gu, ge, go

[0033] <sa> series: sa, shi, su, se, so

[0034] The "za" series: za, ji, zu, ze, zo

[0035] <ta> series: ta, chi, tsu, te, to

[0036] <da> series: da, ji, zu, de, do

[0037] <Na> series: na, ni, nu, ne, no

[0038] <ha> series: ha, hi, fu, he, ho

[0039] <ba> series: ba, bi, bu, be, bo

[0040] <pa> series: pa, pi, pu, pe, po

[0041] <ma> series: ma, mi, mu, me, mo

[0042] <ra> series: ra, ri, ru, re, ro

[0043] <ya> series: ya, yu, yo, wa, wo

[0044] What is noteworthy here is that the keys ya, yu, yo, wa, and wo, which do not correspond to consonants, have been grouped into a single <ya> series, and these keys can be input in the same way as the aforementioned a series to ra series keys. In other words, by grouping "ya, yu, yo, wa, wo" (excluding the a series to ra series keys) into the ya series by assigning a procedure according to the order of vowels, it has become possible to represent all Japanese characters according to the regular order of pronunciation.

[0045] The sequence key section 12 includes a key for selecting the corresponding key in order from among the five keys belonging to each series. That is, when a series is selected by the user from among the series a to ya (e.g., series a), the sequence key section 12 includes a key for selecting the desired key from among the five keys (a, i, u, e, o keys) of the selected series a.

[0046] In the embodiment shown in Figure 4, an example of the five keys forming the sequence key section 12 is the Arabic numeral original text. The key TIFF2026076082000014.tif762 was used. The five keys that make up the sequence key section 12 are not limited to this, and various keys that represent sequence can be used. For example, in the embodiment of Figure 5, the Greek I, II, III, IV, and V keys were used as an example of the five keys that make up the sequence key section 12. Also, in the embodiment of Figure 6, the keys a, i, u, e, and o were used as an example of the five keys that make up the sequence key section 12.

[0047] The user can input (display) any one character from the 65 Japanese characters that make up each series by touching any one of the 14 keys arranged on the series representative key section 11 and any one of the 5 keys arranged on the sequence key section 12.

[0048] For example, when a user wants to input any single character from a series of characters such as a or b, they can input it through the following key operations.

[0049] (a) Input of <あ>: TIFF2026076082000015.tif9116<あ> is displayed.

[0050] (b) Input of <ki>: TIFF2026076082000016.tif8115<ki> is displayed.

[0059] (d) Input of <wa>: TIFF2026076082000023.tif8115<わ> is displayed.

[0060] (e) Input <to>: TIFF2026076082000024.tif8115<to> will be displayed.

[0061] The other key section 13 is for inputting other keys not included in the a series to ya series, such as the small 'k' key, the 'n' key, and the repeating sign 'n' key. The keys of the other key section 13 can be input (displayed) in combination with the keys arranged in the sequence key section 12, as described above. The keys included in the other key section 13 are not limited to the 'k' and 'n' keys; other keys can also be registered and used in advance.

[0063] (b) Input of <n>: TIFF2026076082000026.tif8129<ん> is displayed.

[0064] (c) Input of <々>: TIFF2026076082000027.tif8129<々> is displayed.

[0065] The lowercase versions of the aforementioned "a, i, u, e, o" are "ぁ, ぃ, ぅ, ぇ, ぉ", In TIFF2026076082000028.tif852, input can be done by pressing the corresponding key twice in succession. For example, the characters "ぁ, ぃ, ぅ, ぇ, ぉ" can be entered as follows:

[0066] (a) Input of <ぁ>: TIFF2026076082000029.tif9169<ぁ> is displayed.

[0067] (b) Input of : TIFF2026076082000030.tif8168<ぃ> is displayed.

[0068] (c) Input of : TIFF2026076082000031.tif9169<ぅ> is displayed.

[0069] (d) Input of <e>: TIFF2026076082000032.tif8170<ぇ> is displayed.

[0070] (e) Input of <o>: TIFF2026076082000033.tif10169<ぉ> is displayed.

[0071] The following table compares the number of keystrokes required when inputting Japanese using the present invention versus when inputting Japanese using the prior art (e.g., Figure 1).

[0072] [Table 1]

[0073] [Table 2]

[0074] [Table 3]

[0075] On the other hand, Figure 7 shows a terminal equipped with a Japanese character input device according to an embodiment of the present invention.

[0076] Referring to Figure 7, the terminal 100 equipped with a Japanese input device according to an embodiment of the present invention includes a Japanese input device 10, a control unit 20, a memory unit 30, and a display unit 40.

[0077] The operation of a terminal equipped with the Japanese input device according to the present invention, configured in this manner, is as follows.

[0078] The Japanese input device 10 has the same configuration as the Japanese input device 10 described in Figure 4, and its operation is also the same.

[0079] The control unit 20 recognizes Japanese characters input through the Japanese input device 10 and stores them in the memory unit 30 in a predetermined format (e.g., file format). At the same time, the control unit 20 can recognize Japanese characters input through the Japanese input device 10 and display them on the display unit 40.

[0080] Here, the type of terminal 100 is not particularly limited. For example, the type of terminal 100 may be either a mobile computer device or a fixed computer device. The mobile computer device may be any one of a smartphone, laptop, phablet, tablet PC, personal digital assistant (PDA), or e-book reader, but is not limited to these. The fixed computer device may be any one of a PC (desktop) (Personal Computer), workstation, or server, but is not limited to these.

[0081] Here, if the terminal 100 is a PC, the PC keyboard 110 may be equipped with the series representative key section 11, sequence key section 12, other key section 13, and macro key section 14 as described above, as shown in Figure 8. Here, the other key section 13 differs from the other key section 13 in Figure 4, and another embodiment is shown which includes small "っ" and "ん" keys.

[0082] In Figure 8, the macro key section 14 is equipped with macro keys Y, U, I, and OP. Users can use these to more conveniently input pre-saved idiomatic expressions (e.g., "masu.", "desu.", etc.).

[0083] On the other hand, Figure 9 shows an example of the application of the series representative key section 11 and the sequence key section 12 when the terminal device 100 is a smartphone.
