Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document preparation apparatus which can use a plurality of input devices including a pen device.

[0002]

2. Description of the Related Art In a word processor, a portable word processor having a pen device in addition to a keyboard as an input device and capable of selecting an icon by the pen device has been developed.

In a conventional word processor equipped with this type of pen device, the user switches the display of a plurality of icons or interrupts the display of icons according to the input device (pen device / keyboard, etc.) used. I was giving an operating instruction.

As described above, conventionally, since the icon is displayed according to the operation instruction of the user regardless of the usage state of the pen device by the user, there are the following problems. That is, since the icon for the pen device is displayed even though the pen device is not used, it has been an obstacle to editing.

Further, when the pen device is used, the keyboard icon is displayed or the icon for pen operation is not displayed, which makes it difficult to edit using the pen device. There was an inconvenience. In addition, there is a problem that the operability is poor because the display switching of the icon has to be controlled by a user's operation instruction according to the usage state of the pen device.

[0006]

As described above, in the conventional system configuration, since there is no relation between the usage state of the pen device and the display of the icon, there are various operations. There was an inconvenience.

The present invention has been made in view of the above circumstances,
In a document creation device that enables operation input with a pen device and other input devices such as a keyboard, it is determined whether or not the user is using the pen device, and the icon display is automatically displayed according to the determination result. (EN) Provided is a document creation device which has a function of switching and always matching a display icon with an input device used, and which improves the operability and workability of a system having a plurality of types of operation input devices including a pen device. To aim.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a document creating apparatus which enables operation input by a pen device and another input device such as a keyboard, and determines whether or not the user is using the pen device. A means for judging and a means for switching the display of the icon according to the judgment result are provided,
When the user is not using the pen device, the icon for the keyboard is displayed or the process of interrupting the display of the icon is performed. When the user is using the pen device, the process for displaying the icon for the pen device is performed. It is characterized by performing.

[0009]

In the above configuration, when the user is not using the pen device (when the pen is held in the pen holder), the keyboard icon is displayed or the icon display is stopped and the input is made from the keyboard. Key input processing. Also, when the user is using the pen device (when the pen is removed from the pen holder), the icon for the pen device is displayed and the coordinate input process of the pen device is executed.

As described above, it is determined whether or not the user is using the pen device, the icon display is automatically switched according to the determination result, and the displayed icon is always the input device (pen device / pen device / By adopting a configuration having a function conforming to the keyboard, the operability of the system equipped with the pen device is improved, and the document input and edit processing can be performed smoothly and quickly.

The input process shown in FIG. 2 is executed.

In this input process, after the key input acceptance process of the keyboard 18 (step S1 in FIG. 2) is executed, the usage state (used / unused) of the pen device 15 is recognized (step S2 in FIG. 2). Here, the pen device 15
Whether or not the pen is held in the pen holder is determined by the signal of the detection switch 16 provided in the pen holder, and the usage state of the pen device 15 is recognized.

Here, when the pen of the pen device 15 is held by the pen holder and it is recognized that the pen device 15 is not used, a keyboard icon is selectively displayed on the liquid crystal display (LCD) 20 according to the processing content. It is output (step S3 in FIG. 2).

As described above, in a state where the pen device 15 is not used, the above-described processing including the icon display for the key input of the keyboard 18 is repeatedly executed (steps S1 to S3 in FIG. 2).

At this time, the liquid crystal display (LCD) 20
FIG. 5 shows a display example of the KB icon selectively displayed in FIG. Here, the item selection of the KB icon is performed by the cursor key of the keyboard 18 and the "select / execute" key. The figure shows an example of a state in which the "normal input" of the KB icon is highlighted as the default selection item position.

When the pen of the pen device 15 is removed from the pen holder and it is recognized that the pen device 15 is being used, the pen device icon is displayed on the LCD.
The display output is controlled to 20, and the x and y coordinate input processing of the pen device 15 is executed (FIG. 2, steps S4 and S5).

At this time, the liquid crystal display (LCD) 20
3 and 4 show display examples of the pen icon selectively displayed in FIG. Here, FIG. 3 shows a display example in which the software keyboard is displayed when a pen operation is performed on the “character input” of the pen icon (pointing), and a menu is displayed when the pen operation is performed on the “function” of the pen icon. A display example displayed is shown in FIG. Figure 3
In the display example shown in (1), by pointing an arbitrary key on the software keyboard with the pen of the pen device 15, the pointed character is input at the cursor position (the upper left area of the screen in the figure) of the input area. Further, in the display example shown in FIG. 4, by pointing an arbitrary item of the menu, the process according to the selected item is performed.

In this way, when the pen of the pen device 15 is removed from the pen holder and it is recognized that the pen device 15 is being used, an icon for pen operation is displayed, and pointing by the pen operation causes an arbitrary document to be displayed. Can be created.

As described above, the use of the pen device 15 or the keyboard 18 is provided with the function of judging whether or not the user is using the pen device 15 and automatically switching the icon display according to the judgment result. Since the input device and the icon displayed on the liquid crystal display (LCD) 20 are always aligned with each other, the operability of the system including a plurality of types of input devices including the pen device 15 is significantly improved, and the document input is performed. In addition, the editing process can be performed smoothly and quickly.
