Abstract

PURPOSE:To cope with change and addition of data forms without changing the operation procedures of a display controller by registering correspondence between data forms and display data processor and freely rewriting register contents. CONSTITUTION:A display controller 1 reads out data to be displayed and a data form identifier from a storage device 4 and sends this identifier to a data registering device 7. The data registering device 7 refers to an internal table 6 to determine a processor to be started. The display controller 1 receives this information to start a character data processor 2 or a graphic data processor 3. The character data processor 2 converts the character code into picture data to output it to a display picture 5, and the graphic data processor 3 converts graphic data into picture data to output it to the display picture 5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document processing device capable of displaying a document consisting of a plurality of data strings in different data formats, such as character data, graphic data, image data, etc. It is.

BACKGROUND ART FIG. 8 shows the configuration of a conventional document processing device, in which ■ is a display control device, 2 is a character data processing device for displaying character data, and 3 is a character data processing device for displaying graphic data. A graphic data processing device, 4 a storage device for holding display data, and 5 a display screen for displaying the output of these data processing devices.

The operation of the display control device 1 in the conventional document processing apparatus configured as described above will be explained with reference to the flowchart shown in FIG.

First, the display control device 1 reads data to be displayed from the storage device 4, and selects the character data processing device 2 if the data is character data, and the graphic data processing device 3 if the data is graphic data. The data processing device performs data processing such as converting character codes into image data, and then outputs the data to the display screen 5. Repeat the above steps until there is no more data to display.

Problems to be Solved by the Invention In the document processing device configured as described above, when attempting to newly display data in a third data format such as image data, the character data processing device 2, the graphic data processing device 3 may be replaced with an image data processing device 8 corresponding to the data format of the image data, or a method of increasing the number of display data processing devices. FIG. 10 is an example of the former, in which the graphic data processing device 3 is replaced with an image data processing device 8, and FIG. 11 is a flowchart 1 explaining the operation of the display control device in FIG. . 12 is an example of the latter, in which an image data processing device 8 is added to the configuration of FIG. 8, and FIG. 13 is a flowchart 1 for explaining the operation of the display control device 1 in FIG. It is.

However, with either method, it is necessary to change not only the configuration of the device but also the operation of the display control device 1, which poses problems in versatility and expandability.

The present invention has been made in view of the above, and provides a highly versatile and expandable document processing device that can extremely easily adapt to changes and additions to the format of data to be displayed. The purpose is to provide.

Means for Solving the Problems In order to solve the problems described in item 2, the present invention provides display data processing in which the correspondence between data formats and display data processing devices is registered, and the registered contents can be freely rewritten. It is equipped with a device registration means.

Effects of the present invention By rewriting the registered contents in the display data processing device registration means, it is possible to flexibly respond to changes or additions to the format of data to be displayed without changing the operating procedure of the display control device. can.

Embodiment FIG. 1 is a block diagram showing an embodiment of the document processing apparatus of the present invention.

In FIG. 1, 1 is a display control device, 2 is a character data processing device for displaying character data, 3 is a graphic data processing device for displaying graphic data, 4 is a storage device for holding display data, and 5 is a display screen that displays the outputs of these data processing devices; 6 is a rewritable table that stores the startup method of the display data processing device corresponding to the data format identifier of the display data; and 7 is a table that responds to inquiries based on the data format identifier; This is a data registration device that outputs a startup method for a display data processing device that corresponds to the data format. Figure 3 is an example of the contents of this table 6, and CHR
The column contains the operation necessary to start the character data processing device 2 (out 1), and the column GRP contains the operation necessary to start the graphic data processing device 3 (out 1).
2) is stored.

The operation of the display control device 1 in the document processing apparatus of this embodiment configured as described above will be explained using the flowchart shown in FIG.

First, the display control device 1 reads data to be displayed and the data format identifier of this data from the storage device 4.

In this embodiment, the character data identifier is C H R,
The identifier of the graphic data is GRP.

The display control device 1 then sends this identifier, namely CHR or GRP, to the data registration device 7.

On the other hand, the data registration device 7 refers to the internal table 6 to select out 1 or out
Outputs 2. The display control device 1 is out to the character data processing device 2 and the graphic data processing device 3.
By doing 1 or out 2,
Either the character data processing device 2 or the graphic data processing device 3 is activated.

The character data processing device 2 converts character codes into image data, for example, and the graphic data processing device 3 performs data processing such as converting graphic data into image data, and then outputs the data to the display screen 5. Repeat steps 1-12 until there is no more data to display.

Next, a case in which character data and image data are displayed using this document processing device will be described. In this case, the configuration of the apparatus is as shown in FIG. 4, in which the graphic data processing device 3 in FIG. 1 is replaced with an image data processing device 8.

Further, the table 6 of the data registration device 7 is rewritten as shown in FIG. 5, for example.

At this time, the display control device 1 also reads display data from the storage device 4, identifies its data format, and sends the identifier CHR or IMG to the data registration device 7. On the other hand, the data registration device 7 outputs out 1
Or out 3 is output, thereby starting either the character data processing device 2 or the image data processing device 8.

Also, when handling character data, graphic data, and image data at the same time, if the device configuration is as shown in FIG. 6 and the table of the data registration device 7 is expanded as shown in FIG. The operation is no different from the two examples described in Section 2.

As described above, according to this embodiment, there is a rewritable table that stores the startup method of the display data processing device corresponding to the data format identifier of the display data, and in response to an inquiry based on the data format identifier, the data format By providing a data registration device that outputs a startup method for a display data processing device compatible with It is possible to flexibly respond to format changes and additions.

Effects of the Invention As explained above, according to the present invention, multiple data formats that are children of a data format can be created without assuming in advance the format of the data to be displayed or the data processing device that will process the data. Documents consisting of data columns can be displayed, and even if there is a change or addition to the format of the data to be displayed, it can be flexibly handled without changing the operation procedure of the display control device each time. It is possible to configure a document processing device that can perform
