Keyboard for inputting character and electronic apparatus using the same

A keyboard for inputting characters comprising:

• a separator key which is marked with a separator mark, which is capable of selecting a letter by one stroke of the separator key;
• a code-key marked with a code mark, which is not able to select a letter by one stroke of a code key, while a letter is input by a combination of a code mark followed by a separator mark or a combination of code marks followed by a separator mark;
• wherein, at the time of inputting both Japanese kana by letters, and letters in English, a part of the letters are used for inputting both Japanese kana and letters in English and remaining letters are input by the keys provided for inputting the letters;
• and p1 wherein said keyboard executes inputting of a character by zero, one, or a plurality of strokes of a code key and sequential stroke of a separator key for selecting a letter.

A keyboard for inputting characters comprising:

• a separator key which is marked with a separator mark, which is capable of selecting a letter by one stroke of the separator key;
• a code-key marked with a code mark, which is not able to select a letter by one stroke of a code key, while a letter is input by a combination of a code mark followed by a separator mark, or a combination of code marks followed by a separator mark:
• wherein, at the time of inputting both Japanese phonetic characters by letters and letters in English, the allocation of the separator marks and part of the code marks are changed for inputting Japanese phonetic characters and for inputting letters in English, and the allocations of the remaining separator marks and code marks are maintained without changing the marks;
• and
• wherein said keyboard executes inputting of a character by zero, one, or a plurality of strokes of a code key and sequential stroke of a separator key for selecting a letter.

A keyboard for inputting characters comprising:

• a separator key which is marked with a separator mark, which is capable of selecting a letter by one stroke of the separator key, wherein at the time of inputting Japanese phonetic characters using letters, vowel keys such as the “A”, “I”, “U”, “E”, and “O” keys are designated as said separator keys;
• a code-key marked with a code mark, which is not able to select a letter by one stroke of a code key, while a letter is input by a combination of a code mark followed by a separator mark, or a combination of code marks followed by a separator mark, wherein a first key group of alphabetical letter keys corresponding to the consonants of said Japanese phonetic characters composed of five consonant letters which have the highest appearance frequency among said Japanese phonetic characters are designated as said code keys, and a second group of five characters, excluding said first five characters are input by two sequential strokes of keys corresponding to the first group of code keys, and a third group of phonetic characters are input by two sequential strokes of keys excluding said first key group;
• and
• wherein said keyboard executes inputting of a character by zero, one, or a plurality of strokes of a code key and sequential stroke of a separator key for selecting a letter.

A keyboard for inputting characters comprising:

• a separator key which is marked with a separator mark, which is capable of selecting a letter by one stroke of the separator key;
• wherein, when inputting Japanese phonetic characters by letters, five keys among ten numeral keys from “0”, “1” to “9” are assigned as said separator keys for inputting the five letters of A, I, U, E, and O, corresponding to vowels, and when inputting letters in English said ten numeral keys from “0” to “9” are allocated to keys from “A”, “I”, “U”, “E”, “O”, “K”, “S”, “T”, “N”, to “H” keys which are assigned as said separator keys;
• a code-key marked with a code mark, which is not able to select a letter by one stroke of a code key, while a letter is input by a combination of a code mark followed by a separator mark, or a combination of code marks followed by a separator mark, wherein, when inputting Japanese phonetic characters by letters the remaining five numeral keys of said ten numeral keys are assigned as said code keys for inputting the consonants of K, S, T, N, and H which have the second highest appearance frequency excluding vowel syllables, and the remaining consonants are input by sequential strokes of the same code keys or by sequential strokes of different code keys, and when inputting letters in English, the “*” and “#” keys are assigned to be said code keys and the consonants of F, J, L, Q, C, M, Y, R, W, and P are input by sequential strokes of said separator keys following to a hit of said “*” key, and letters X, space, comma, period, V, G, Z, D, N, and B are input by a sequential stroke of said separator keys following to a hit of the “#” key;
• and
• wherein said keyboard executes inputting of a character by zero, one, or a plurality of strokes of a code key and sequential stroke of a separator key for selecting a letter.
