Abstract
A character input apparatus contains a ROM that stores the character change pattern for each character according to where the character is in a string of characters, and a character reader for reading the characters before and after the entered character. When a character is entered from an input unit, the characters before and after the entered character are read by the character reader, and the change patterns corresponding to the entered character and the characters before and after the entered character are read from the ROM. This makes it possible to enter such concatenated characters as those written in one stroke, and further enter characters in a language where the form of each character changes according to the preceding and succeeding characters.
Claims12
A character input apparatus comprising:
- character writing selection means for selectively switching between a right-to-left input state for a right-to-left character writing manner in which characters are written from right to left, and a left-to-right input state for a left-to-right character writing manner in which characters are written from left to right;
- a character input device for successively inputting characters;
- a character display device for displaying the successively input characters;
- right-to-left character writing display control means for controlling said character display device to shift an already displayed preceding input character in a rightward direction and to display a succeeding input character at a position leftward of the shifted preceding input character in a case where the right-to-left input state is selected by said character writing selection means and when the succeeding character is input with respect to the already displayed preceding input character after the right-to-left input state has been selected by said character writing selection means;
- left-to-right character writing display control means for controlling said character display device to display the succeeding input character at a position rightward of the shifted preceding input character in a case where the left-to-right input state is selected by said character writing selection means and when the succeeding character is input with respect to the already displayed preceding input character after the left-to-right input state has been selected by said character writing selection means.

- right-to-left character writing display control means for controlling said character display device to display the succeeding input character at a position leftward of the shifted preceding input character in a case where the right-to-left input state is selected by said character writing selection means and when the succeeding character is input with respect to the already displayed preceding input character.
A recording medium storing a program for controlling a computer, said computer being coupled to a character input device for successively inputting characters and a display device for displaying the successively input characters, and said program controlling said computer to function as:
- mode selection means for setting one of a right-to-left input state for a right-to-left character writing manner in which characters are written from right to left, and a left-to-right input state for a left-to-right character writing manner in which characters are written from left to right;
- right-to-left character writing display control means for controlling said character display device to shift rightward an already displayed preceding input character input when said right-to-left input state was not set, and to display a succeeding input character at a position leftward of the shifted preceding input character in a case where the right-to-left character input mode is set by said mode selection means;
- and
- left-to-right character writing display control means for controlling said character display device the succeeding input character at a position rightward of the preceding input character in a case where the left-to-right character input mode is set by said mode selection means.

- left-to-right character writing display control means for controlling said character display device to shift leftward an already displayed preceding input character input when said right-to-left input state was not set, and to display a succeeding input character at a position rightward of the shifted preceding input character in a case where the left-to-right character input mode is set by said mode selection means;
- and
- right-to-left character writing display control means for controlling said character display device the succeeding input character at a position leftward of the preceding input character in a case where the right-to-left character input mode is set by said mode selection means.
