In a mobile terminal device referred to as t), a tablet that also serves as a liquid crystal display screen is used as an input device, and data input is performed using a dedicated input pen.
In addition, a computer equipped with a handwritten keyboard having a pen pad capable of performing handwritten input instead of the conventional JIS keyboard has appeared.

In a device for inputting data such as characters and symbols in accordance with such a pen instruction, when a character is handwritten, several grid-like character input frames are displayed on a display screen, and the characters are input. The method of handwriting input in the input frame is adopted. Then, the characters input by hand in this input frame are recognized by detecting the coordinates indicated by the pen and detecting the stroke data, and are recognized by analyzing the stroke data. In order to improve the recognition rate, icons for specifying the recognition priority, such as "recognition priority designation icon" and "full-width half-width designation icon", are provided on the pen pad to enable various input modes to be selected and handwritten input There is a function to specify the character type of the data.

[0004] When a "recognition priority designation icon" or the like is selected, the selected icon is highlighted and the operator sees the highlighted display to confirm which input mode is currently set. Also, when using a pen pad with such a recognition priority function, normally set the input mode to the default setting (in most cases, all types of recognition and full-width input mode), and if the input characters are difficult to recognize Then, a desired input mode such as “Hiragana priority recognition” is changed.

[0005]

However, in the above-described method of identifying an input mode by inverting an icon, it is necessary to check whether the current input mode is a default setting mode or another mode. It is necessary to search for the highlighted icon from among a plurality of icons, and if the user forgets to return the set input mode, the icon is converted to a character type different from the desired character.
There has been a problem such as an input error.

An object of the present invention is to solve the above-mentioned problems, and when the currently set input mode is different from the default setting mode, the entirety of the pen pad so that the operator can easily recognize that. Alternatively, by changing the color of a part of the background, or by changing the display pattern of the background, the input mode can be easily identified, and a recognition priority function for improving the character recognition rate can be realized. An object of the present invention is to provide a data input device capable of further improving convenience.

[0007]

By selecting the desired option from multiple options,
What is claimed is: 1. A data input device capable of setting a predetermined function related to data input, comprising: storage means for storing a different background color or background pattern for each of the plurality of options; and selecting from the plurality of options. When a predetermined input area is displayed on the display screen of the display means corresponding to the determined option, the background color or the background pattern stored in the storage means corresponding to the option is determined. And display control means for displaying in the input area.

According to the data input device of the first aspect of the present invention, a predetermined function related to data input can be set by selecting a desired option from a plurality of options. A different background color or background pattern is stored in the storage unit in correspondence with each of the plurality of options, the option selected from the plurality of options is determined, and a display on the display unit is displayed in accordance with the determined option. When displaying a predetermined input area on the screen, a background color or a background pattern stored in the storage means corresponding to the option is displayed in the input area.

Therefore, by selecting a desired option, a background color or a background pattern corresponding to the option can be displayed in the input area. For example, a desired input mode can be selected from a plurality of input mode options. By selecting, the background color or background pattern corresponding to the input mode is displayed in the input area, and the operator can see at a glance the background color or background pattern displayed in this input area to determine the current input mode. It is possible to easily identify whether the input mode is set, and it is possible to reduce forgetting to return to the input mode, thereby reducing character recognition errors and character recognition delays. The priority recognition function by selecting the mode can be effectively used.

It is determined by referring to the attribute designation register 92 set at 0 (step S54).

If the table selection register 91 is not set (NULL), the CPU 2 determines whether the display device 5 is a color display or a monochrome display (step S51). The table 93 is used (step S52), and for monochrome display, the pattern attribute table 94 is used (step S52).
53).

Next, the CPU 2 refers to the display change point designation register 95 and determines which range of the display of the pen pad 20 is to be changed (step S60). When the set value of the display change portion designation register is 0, the pen pad 2
The display of the background of the whole 0 is changed (step S61), and when the set value is 1, the display of the background of the handwriting input area 50 is changed (step S62), and the background change processing is completed.

As described above, when an icon (recognition priority designation icon 30 or full-width half-width designation icon 40) for switching to a desired input mode is selected from the icons displayed on the pen pad 20, the icon is displayed. The attribute is determined, and the display of the background is changed with the display color or display pattern corresponding to the selected input mode. The background color or display pattern is defined in advance corresponding to the input mode, and changes according to an instruction to switch the input mode. It is possible to easily identify whether the input mode is the setting mode or the other input mode, and it is possible to avoid forgetting to return the input mode.

As a result, character recognition errors and character recognition delays caused by forgetting to return to the input mode can be reduced, and the time required for data input can be reduced.
