ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a character data input apparatus suitable for use in a portable computer to which characters in handwriting can be input.
2. Description of the Related Art
FIG. 21
shows an example of structure of a character inputting means in a conventional portable computer. In a character input screen formed for example of an LCD and a tablet, there is displayed a type plate A as a window on a page plate F. The type plate A has a plurality of squares B. When a character handwritten with a pen E is input to a tablet in a square B where a character cursor C is located, a locus traced by the pen E is displayed in the square B. The traced locus is then subjected to pattern recognition and a character obtained as a result of the pattern recognition is displayed in the square B instead of the traced locus. In the present example, there are input and displayed characters “3”, “A”, and “-” in three squares B.
Here, it is difficult to determine whether the character “-” displayed in the third square B is a minus sign “−” or a hyphen “-”. Therefore, there is provided a character kind indicator portion D at the lower right of the type plate A to indicate to which character kind of ‘capital’, ‘number’, ‘symbol’, and ‘Greek’ the character displayed in the square B where the character cursor C is located belongs. More specifically, when the character is a capital, the indicator for ‘capital’ is lighted. Likewise, when the character is a number, a symbol, or a Greek letter, the indicator for ‘number’, ‘symbol’, or ‘Greek’ is lighted. By looking at the display in the character kind indicator portion D, the user is enabled to determine that the character displayed in the square B where the character cursor C is located is ‘capital’ letter, ‘number’, ‘symbol’, or ‘Greek’ letter.
In the conventional character data input apparatus, as described above, it was arranged such that the kind of the character displayed in the square B where the character cursor C is located is displayed in the character kind indicator portion D. Since the type plate A has eight squares B, in order to know the kind of the character displayed in a square B, the character cursor C must be shifted to that square. This has been an inconvenience.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above described situation. Accordingly, an object of the invention is to make it easier to recognize information related to the character such as character kind.
In order to achieve the above mentioned object, the character data input apparatus of the present invention of a type of character data input apparatus displaying a plurality of input characters in a plurality of areas of the display portion is arranged such that each of the plurality of character displaying areas has a first area for displaying the input character and a second area for displaying information related to the character displayed in the first area.
In the character data input apparatus of the above described arrangement, each of the plurality of areas in the display portion displaying a plurality of characters is divided into the first area and the second area. The input characters are displayed in the first areas and information related to the displayed characters is displayed in the second areas. Accordingly, the user can see information related to the plurality of characters at the same time.
