Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing device such as a word processor which executes a predetermined process based on a coordinate signal output from a coordinate input device such as a tablet.

[0002]

2. Description of the Related Art Conventionally, in a processing device that executes a process based on a predetermined application program such as a word processor or an electronic notebook,
As a means for inputting handwritten characters and figures, for example, by combining a liquid crystal display (LCD) and an electrostatic induction type tablet, the operator writes the characters and figures input to the electrostatic induction type tablet on paper with a writing instrument. There is a device in which the input is made as if it were different and is displayed on the LCD.

Such a tablet has improved operability as compared with a key input operation using a keyboard or the like, for example, when an operator selects various modes displayed on the LCD during execution of an application program. Can be made In the case of such a tablet as described above, for example, a sheet-like tablet having a large number of input points is superposed on an LCD, and the input point is detected by a position detection pen (hereinafter simply referred to as a detection pen). When instructed, a coordinate signal corresponding to this input point is output and used as data for processing. The processing device can recognize that the coordinate signal designates, for example, a region for mode selection displayed corresponding to the input location, and can continue the processing.

For example, in a document processing device such as a word processor, an input by a tablet which is performed during execution of an application program such as a document creation process is necessary for a document creation process to be displayed in each divided area on an LCD. For example, the input mode may be switched or the operator may select a mode such as character modification. In the case of such a so-called pointing mode, the operator designates a necessary area among the areas representing the various modes as described above with the detection pen, and the coordinate signal related to the area is output. The mode can be executed.

Further, as another input by the tablet, there is a case of a so-called docking mode, in which handwritten characters and arbitrary figures are displayed on the LCD. For example, when the operator writes, for example, "A" on the LCD with a detection pen, the handwritten "A" is displayed on the LCD. This is because when the input points are continuously pointed by the detection pen, the coordinate signals corresponding to all the pointed input points are output, so that the processing device processes the coordinate signals and displays the LCD as handwriting. Display on top.

FIG. 7 is a block diagram showing the basic configuration of the above-mentioned processing apparatus 1, and FIG. 8 is a flow chart showing the processing operation of the coordinate signal in the pointing mode. As shown in FIG. 7, the coordinate signal output from the tablet 2 is transferred to the CPU (central processing unit) 3, and each processing in the pointing mode or the docking mode is performed based on this signal. For example, in the pointing mode, as shown in FIG. 8, first in step a1, the state of the detection pen and the coordinate system are acquired, and in step a2 it is determined whether or not the detection pen is in contact with the LCD screen. When not in contact, the process returns to step a1, and when in contact, the state of the detection pen and the coordinate system are further acquired in step a3, and then it is determined in step a4 whether or not the detection pen has been separated from the LCD screen. If it is not separated, the process returns to step a3. If it is separated, the region is calculated from the coordinate system of the detection pen in step a5, and the process is performed based on the region calculated in step a6. As described above, in the pointing mode, the area pointed to when the detection pen is released after the area where the detection pen is to be specified is touched is specified.

[0007]

As described above, the coordinates of the detecting pen and the state of the detecting pen are sequentially output from the tablet, and the processing device outputs all the coordinate signals output in the pointing mode. Recognizes the coordinate signal when the detection pen is separated from the screen as an effective signal for area designation, and proceeds to the subsequent processing.

However, in the pointing mode for originally designating the area, the information necessary for the processing, that is, the information as to which coordinate the detection pen has designated is output when the detection pen touches the screen and leaves. Although only one coordinate signal is required, as described above, only one useful coordinate signal is identified from all unnecessary coordinate signals unrelated to processing. It is necessary to always perform the processing, which forces the processing device to perform useless processing.

Therefore, the processing apparatus is added with the coordinate signal identification processing as described above in addition to the predetermined processing for executing the application program for creating a document as described above. However, there is a problem that the program becomes complicated and eventually the program capacity is increased.

Therefore, it is an object of the present invention to provide a processing apparatus which can simplify the processing steps when executing a predetermined processing.
