Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device,
In particular, the present invention relates to a document processing device such as a text editor, word processor, file viewer and the like.

[0002]

2. Description of the Related Art In a conventional document processing apparatus, as a function of moving or changing a position for performing various kinds of document processing on an input document, a mark is placed at an arbitrary position of the document, and if necessary, later, There is a function to move the document to the marked position. Usually, a plurality of positions can be marked, and the user can select the position to move from.

[0003]

Considering the present document processing, the function of marking a document and the function of moving to the position of the mark are described as "marking the current processing position and once It is often used to move to the position of ", return to the previous position after doing some other processing there."

In practice, however, it rarely returns to the previous position immediately after the movement, and a similar state also occurs at the moved position, and a mark is often added to move again. In the current document processing device, all marks are handled at the same level, so if you repeat this process, the number of marked positions will increase, and you may not be able to know which position is right before returning. , It's not easy to use. In addition, it is often necessary to return to the previous position and then return to the position before the return, but since the position before the return is not automatically maintained, the user must I have to put a mark at the destination. As described above, conventionally, the user needs to manage the marks, and the operation is troublesome.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a document processing apparatus which is easy to use and prevents erroneous operations when moving or returning a cursor.

[0006]

A document processing apparatus according to the present invention includes a display unit for displaying a document, a moving unit for moving a cursor in the displayed document to a designated position, and a moving unit. The returning means for returning the moved cursor to the original position, the managing means for managing the designated position and the original position, and the operation of the moving means and the returning means based on the managed position. And control means for controlling.

[0007]

In the present invention, the control means controls the operations of the moving means and the returning means based on the managed position.

[0008]

1 is a system block diagram showing the configuration of a document processing apparatus according to an embodiment of the present invention.

In the figure, a document processing apparatus according to the present invention includes an input device 2 for inputting a document, a processing device 3 for processing the input document, and a display device 1 for displaying the input document on a screen. Storage device 4 for storing the input document
And a management device 5 that manages a mark added for moving or returning the cursor, and an instruction device 6 for instructing movement or change to a processing position using the mark. The management device 5 is provided with three FILO type (stack type) storage areas as means for storing the position of the attached mark. Stack each storage area
1, stack-2, and stack-3. In addition,
In the initial state when the document processing device is activated, the storage contents of all stacks are empty.

In the pointing device 6, there are "remember" for marking the current position of the cursor to be moved or restored, "remember" for returning the cursor to the marked position and "return" for returning the cursor to the position before the return. Three types of processing operations can be instructed.

FIG. 2 is a flow chart showing a main flow for moving or returning the cursor, which is performed by the management device 5 and the pointing device 6 of FIG.

In the figure, first in step S1,
It is determined whether or not the instruction from the instruction device 6 is a “remember” process. If the instruction is the "remember" processing, the "remember" processing is performed in step S2. If the instruction is not the "remember" processing, step S2 is skipped and the flow proceeds to step S3.

In step S3, it is determined whether the instruction from the instruction device 6 is a "remember" process. If the instruction is the "remember" process, the "remember" process is performed in step S4, and then the flow proceeds to step S5. If the instruction is not the "remember" process, step S4 is skipped. Then, the flow proceeds to step S5.

If it is determined in step S5 that the instruction from the instruction device 6 is the "return" processing, if the instruction is the "return" processing, after the "return" processing is performed in step S6. , The flow proceeds to step S7, but if the instruction is not “return”, step S6 is skipped and the flow proceeds to step S7.

In step S7, it is determined whether or not the instruction to move or change is completed. If the move or change instruction continues, the flow returns to step S1 and the same processing as above is performed. When the move or change instruction is completed, the operation of the cursor move or change process ends.

FIG. 3 is a flow chart showing the specific contents of the processing to be remembered in FIG. In the figure, step S2
In 1, the current position of the cursor scheduled to be moved or changed is compared with the value of the head address stored in the stack-1 included in the management device 5. If the compared values are the same, the flow returns as it is, but if the compared values are different, step S
At 22, the address indicating the current position is stack-1
Stored in the storage area of. In addition, already in stack-1,
When a certain address is stored, it is stored so that the address of this current position is stacked on it.

Then, in step S23, the storage area stacks-2 and 3 included in the management apparatus 5 are stored.
After erasing the stored contents of, the flow returns.

FIG. 4 is a flow chart showing the specific contents of the "remember" process of FIG. In step S41, it is determined whether or not there is content already stored in the stack-1 of the storage area. If there is no stored content, the flow returns as it is,
If a certain address is stored, step S42
Then, the address of the current position is stored in the storage area of stack-2. If a certain address is already stored in the storage area of stack-2, the address indicating the current position is stored above the address.

Next, in step S43, the value of the address stored in the storage area of stack-1 is fetched, and in step S44, the value of the fetched address is stored in the storage area of stack-3. Similarly, if an address already stored in the storage area of stack-3 is stored,
The value of the address fetched from stack-1 will be stored above that address.

Further, in step S45, after the cursor is moved to the position indicated by the value of the address fetched from stack-1 in step S43, the flow returns.

FIG. 5 is a flow chart showing the specific contents of the "return" process of FIG. In step S61, it is determined whether or not an address is stored in the storage area of stack-2. If nothing is stored, the flow returns as it is, but if a certain address is stored, in step S62, the value of the address stored in the storage area of stack-3 is extracted and the value is stored. Is stored in the storage area of stack-1.
Here, when a value already stored in the storage area of stack-1 is stored, the value of the fetched address is stored above that value. Further, in step S63, the value of the address stored in the storage area of stack-2 is fetched, the cursor is moved to the position indicated by the address, and then the flow returns.

FIG. 6 is a diagram showing a specific example of how the cursor is moved or returned by the control shown in the flow of FIGS. 2 to 5 above.

In the figure, in the operation column, items shown from to indicate the respective contents of the operation, and A and B shown in the column of the current position are cursors to be moved or restored. It represents the address position in the processed document. Each of the stack-1, stack-2, and stack-3 columns includes the management device 5 as described above.
3 shows the storage contents of a storage area included in the storage device.

In the figure, it is assumed that the head address of the cursor to be moved is at address A. In this case, since the document processing apparatus has been activated, nothing is stored in the storage areas of stack-1 to stack-3, and the state is empty.

Next, when the operation of "remember" is designated by the management device 5, the processing of the contents of the flowchart shown in FIG. 3 is performed. That is, since the address of the current position is A and there is no value stored in the area of the stack-1, the address A indicating this current value is stored in the area of the stack-1 by the process of step S22 of FIG. It will be stored in the area.

Next, it is assumed that the pointing device 6 gives an instruction to move the cursor of the document from the position of the address A to the address B. In this case, the contents of the areas from stack-1 to stack-3 remain unchanged, and stack-1
Therefore, the address A is stored only in the area. When moving, specifically, a mark is attached to the display position of the screen corresponding to the address B.

Next, the original position already marked,
That is, it is assumed that the "remember" process is designated to perform the operation of returning the cursor to the position corresponding to the address A. In this case, the processing is performed according to the contents of the flow of the "remember" processing shown in FIG. here,
Since the address A has already been stored in the stack-1, the address indicating the current position, that is, the address B is stored in the stack-2 as shown in step S42, and the stack- is processed by the process of step S43. 1
The address A stored in is fetched and its value is stored in stack-3. Then, the cursor is moved to the value stored in the area of stack-3, that is, the position on the screen corresponding to the address A. Here, when the cursor is to be returned to the position before the return, that is, the position of the address B, by the pointing device 6,
The designation of "return" is made. In this case, the cursor moving process is performed according to the contents of the flowchart shown in FIG. That is, in this case, stack −
Since the address B is already stored in the storage area of No. 2, the value stored in the stack-3, that is, the address A is taken out and the value is stored in the storage area of the stack-1 in step S62. .. Further, in step S63, the value stored in stack-2, that is, address B, is taken out, and the cursor moves to that position. As a result, the cursor moves to the position on the screen corresponding to the address B again.

FIG. 7 is a diagram showing a specific example in which a plurality of moving or returning processes are further performed after the operation shown in FIG. 6 is performed.

The contents of the operation are shown in the column of the operation, and the position of the cursor associated therewith is shown in the column of the current position. Similar to FIG. 6, the states of the addresses stored in the respective storage areas are shown in the areas of the columns of stack-1 to stack-3.

First, it is assumed that the final state shown in FIG. 6, that is, the cursor exists at the position on the screen corresponding to the address B and is moved from that position to the position on the screen corresponding to the address C. .. In this case, a mark is added to the position of the screen corresponding to the address C as a mark of the moving destination, but the stored contents of the storage areas from stack-1 to stack-3 do not change. Next, it is assumed that an instruction of “remember” processing is given as an operation of remembering the position of the destination address C. In this case, since the current position is the address C and the address value stored in the stack-1 is A, which is different, the address of the current position, that is, C is the stack-
1 will be stored on the address A already stored in 1. In this case, the contents of the areas of stacks-2 and 3 are not present, so that the process of step S23 is not substantially performed.

Next, from the current position C, a new address D
It is assumed that the position on the screen corresponding to is marked and the cursor is further moved. In this case as well,
The contents of the storage areas of stack-1 to stack-3 do not change. Next, it is assumed that the "remember" process is designated to restore the document currently located at D to the already marked position C. In this case, the address C
It is not necessary to newly mark the position on the screen corresponding to the position of. That is, the current position, that is, the address D is stored in the storage area of the stack-2 by the processing of step S42, and the value stored in the storage area of the stack 1, that is, the value of the address C is extracted by the processing of step S43. Stored in the storage area of stack-3. Then, the cursor is moved to the position on the screen corresponding to the value fetched from the area of stack-1, that is, the position of address C.

In this state, the stored address A is again instructed by the instruction of the "remember" process by the operation.
It is assumed that a "remember" process is specified in the operation in order to return the cursor to. in this case,
In step S42, the current position, that is, the address C
The value of is stored in the storage area of the stack-2, but since the address D has already been stored in this area, the address C will be stored there.

Then, by the processing of step S43,
The value stored in the stack-1, that is, the address A is fetched, and the value is stored in the storage area of the stack-3. The storage area of stack-3 already has address C
Is stored, the address A is stored there. Then, the cursor moves to the position on the screen corresponding to the value, that is, the position of the address A fetched from the stack-1.

Here, in order to return the cursor to the state before the movement, that is, the position corresponding to the address C, "return" is performed.
It is assumed that the processing has been specified. In this case, the address A is fetched from the area of stack-3 by the process of step S62, and the value is stored in the storage area of stack-1. Then, in step S63, the address C stored in the storage area of the stack-2 is taken out, and the cursor is returned to the position on the screen corresponding to the value. Further, it is assumed that a "return" process is designated to further return the cursor to the position before that, that is, the position corresponding to the address value D. In this case, by the process of step S62, the value stored in the area of stack-3, that is, the address C is taken out, and the value is stored on the value of address A already stored in stack-1. Further, in step S63, the value stored in the stack-2, that is, the address D is taken out, and the cursor is moved to the position on the screen corresponding to the position, so that the cursor is moved to the position on the screen corresponding to the address D. I will be back.

As described above, according to the embodiment of the present invention, since the mark managing means of the moving or returning destination is included in the document processing apparatus, the following operating environment for the document processing is provided. It

First, when a mark is added to the current position,
Even if there are multiple marks, simply add the marks. The operator does not need to be aware of making multiple marks.

Next, when returning to the marked position, the operator refers to the marked order and automatically returns to the last marked position. No need to remember. At this time, if the mark is attached multiple times, it is possible to perform the return processing multiple times, but since the return position is automatically stored, the operator need not be aware of that at all. ..

Further, at the time of returning, by automatically storing the position, it is possible to return to the position before the returning after returning once. The operator does not need to remember the position before the return, and does not need to separately perform the operation of storing the position before the return. At this time, if the return is performed multiple times, it is possible to return multiple times, but since the position before each return is automatically memorized, the operator must be fully aware of that and use it. There is no.

In the above embodiment, three stacks are arranged as storage areas, but the number of stacks is not limited to three, and the idea of the present invention can be applied by using more stacks. Is.

In the above embodiment, the stack is set to FI.
Although the LO type storage device is used, it goes without saying that another storage device may be used as long as the stored contents can be taken in and out in the order shown above.

[0041]

As described above, according to the present invention, the operation of the moving means and the returning means is controlled by the control means based on the managed position, so that the cursor can be moved and returned with high reliability, and the usability is improved. improves.
