Description

Description: TECHNICAL FIELD The present invention relates to a document processing apparatus capable of deciding a layout position of a document area on a print sheet based on stored format data.

[Prior Art] A layout showing the frame of a paper such as a CRT and the layout of the document with respect to this frame so that the layout of the document printed on the paper can be known in advance in a word processor or the like. It is known to display a screen (generally displayed in a reduced size). Therefore, when the user is satisfied with the displayed layout, the user can instruct the printing, and the layout is exactly the same as the one seen on the CRT, and it is convenient.

[Problems to be Solved by the Invention] However, if the displayed layout is not acceptable, the layout must be changed. In the prior art,
Due to this change, the contents of the document memory and the contents of the display RAM had to be rewritten from the front, which required a large amount of internal processing. Therefore, it takes a considerable time from the user's key input of the change instruction until the changed layout is displayed, and the response is poor.

In addition, when changing the layout, it is necessary to change the numerical data values themselves such as the left margin and the upper margin, and the actual layout will be displayed depending on the change in the numerical data. However, there is a problem in that it is necessary to change the numerical data and display the layout repeatedly in some cases.

An object of the present invention is to make it possible to easily change and set the relative positional relationship between the document area and the printing paper.

[Means for Solving the Problems] Means of the present invention are as follows.

Format data storage means for storing format data for determining the layout position of the document area with respect to the print sheet, and a relative layout positional relationship between the paper layout frame of the print sheet and the range of the document area based on the format data. Display means for displaying an image on the display screen according to the display form of the relative display positional relationship between the display image of the paper layout frame and the display image of the document area range, the display image of the document area range, and the paper layout frame display. When the image and the image are displayed on the display screen, the display mode of the relative display position relationship between the display image of the document area range and the paper layout frame display image can be arbitrarily set on the display screen. Display position changing means, a display image of the document area range by the display position changing means, and Changes in the relative display position relationship between the paper layout frame display image has a format changing means for changing the format data which determines the position of the document area to said printing paper.

[Operation] The operation of the means of the present invention is as follows.

Based on the format data that determines the layout position of the document area with respect to the print paper, the relative layout positional relationship between the paper layout frame of the print paper and the range of the document area indicates the paper layout frame display image and the document area range display image. An image is displayed on the display screen according to the display form of the relative display position relationship with. When the display image of the document area range and the paper layout frame display image are displayed on the display screen, the display image of the document area range and the paper layout frame display image are relative to each other. When the display form of the display positional relationship is arbitrarily changed on the display screen, the relative display positional relationship between the display image of the document area range and the paper layout frame display image is changed to the print paper. The format data that determines the layout position of the document area is changed.

Therefore, only by directly changing the display form of the relative display position relationship between the display image of the document area range and the paper layout frame display image displayed on the display screen, the changed display position relationship can be obtained. The format data that determines the layout position of the document area on the print paper can be changed so that the operator does not have to be aware of the internal format data at all, and the display of the layout position relationship that the operator wants to print out is simply displayed. The format can be changed to a desired format only by changing and designating the display image of the form itself on the display screen.

[Example] Hereinafter, an example of the present invention will be described in detail.

Structure The structure of this embodiment is shown in FIG. In the figure, 1 is a CPU that controls the entire apparatus.

Is used to move the paper frame on the layout screen. The key input from the keyboard 2 is CP via the key input control unit 3.
Input to U1.

Reference numeral 4 is a dictionary memory, 5 is a document memory, 6 is a character generator, and these are read and written via the CPU 1.

Reference numeral 7 denotes a working register group used by the CPU 1. The register LS has a left margin (left space) of the document on the paper, the register TS has a top margin (top space) of the document, and the register mc has a layout. The maximum number of characters / line of a page, the number of input lines of the page to be laid out in the register l, the right margin (light space) of the document in the register RS, and the bottom margin (bottom space) of the document in the register BS. Is stored (see FIG. 2 showing the layout screen). Further, the register MC stores the maximum number of characters that can be accommodated in one line of the paper used, and the register ML stores the maximum number of lines that can be accommodated in the paper used (see FIG. 2).

Reference numeral 8 denotes a layout display unit for displaying a layout screen composed of a paper layout frame 8-1 and a document data layout area 8-2 as shown in FIG. 2, and is for displaying the contents of the display RAM 9. In the display RAM 9, the display data of the paper frame is controlled to be written through the paper layout display control unit 10, and the area of the document data (data displayed as a group of dots) is written through the document layout display control unit 11. Controlled. As will be described later, in this embodiment, it is possible to adjust the layout or position of the document with respect to the paper by rewriting only the paper frame data in the display RAM data. In this case, the documents in the document memory 5 and the display RAM 9 are adjusted. No need to rewrite data.

Reference numeral 12 denotes a document data display unit for displaying normal document data (typically a document edit screen), and a document data display control unit.
The created data is displayed on the display RAM 13 via 14. The layout display section 8 and the document data display section 12 are
This is a function that is selectively displayed on the CRT. Of course, it is possible to use a certain window on the screen of the CRT as a layout screen and another document data screen.

Reference numeral 15 denotes a printer, which executes printing via the print control unit 16.

Operation Next, the operation of the embodiment configured as described above will be described. FIG. 3 (a) shows the overall flow in the case of printing, in which G1 performs formatting such as determining the size of the printing paper, the left margin, and the upper margin. Since the paper size and the like are determined by this format setting, the maximum number of characters MC that can be printed on one line of the paper and the maximum number of lines ML that can be printed on one page are also determined. Document input processing is performed in G2, which causes display RA
Paper frame data and document data are set in M9. Then, the layout display is performed by calling the layout screen at G3, and the key processing is performed for the next layout key operation (G4). Then, the cursor is operated to move the paper frame (G5), and finally the printing is executed according to the print command (G6).

Details of the layout key processing are shown in FIG. First, in step S1, the CPU 1 sets the left space LS in the register LS, and in step S2, searches the document memory 5 for the line with the maximum number of characters in the current page (page displayed on the layout screen). The maximum number of characters mc obtained as a result is set in the register mc in step S3. And RS = MC-
The light space RS is calculated according to LC-mc and stored in the register RS (step S4). Further, the top space TS is stored in the register TS, and the input line number l of the current page is stored in the register l.
(Steps S5 and S6). And BS = ML-TS-1
Then, the bottom space BS is obtained according to and set in the register BS (step S7).

Details of the paper frame moving process are shown in FIG. When any cursor key is pressed, this is detected in step T1, in step T2 it is checked whether or not it is the left / right key, and if so, in step T3 it is checked whether it is the right key or not. At step T4, it is checked whether LS = 0, that is, there is no left space, and if left, at step T6, the left space is decremented by -1 and the right space is decremented by 1, and at step T7, the current LS and TS values (paper Upper left which is the reference position of and document data (document frame)
Based on the data indicating the positional relationship with the upper left of the), the paper layout display control unit 10 is activated to rewrite the position occupied by the paper frame in the display RAM 9 and display it on the layout screen.
As a result, on the initial layout screen shown in FIG. 2, only the paper layout frame 8-1 is moved to the right and displayed one by one.

In step T4, when LS = 0, that is, when the current left space does not remain, NOP is set. As a result, the document area can be secured within the frame of the paper.

Similarly, when the left key is pressed, the right left space is decremented by 1 and the left space is decremented by 1 (step
T8, T9). Similarly, when the down key is pressed, the top key is decremented by -1 and the bottom space is decremented by 1 if the top space remains (steps T1, T11, T12), and when the up key is pressed, the bottom space remains. If so, the bottom space is decreased by -1 and the top space is increased by +1 (steps T13, T1).
Four).

In this way, the user operates the cursor keys 2-2 as appropriate to move the paper layout frame on the layout screen. Since this is done with a fast response,
The user can easily find the best balance. FIG. 2B shows an example of such movement.

Finally, when the user gives a print instruction via the print keys 2-3, the CPU 1 obtains the print start position of the print document on the paper based on the values of the left space and the top space in the resist TS and LS. , To the print control unit 16.
Thus, the print control unit 16 controls the printer 15 to print the document data provided via the document memory 5 and the CPU 7 so that the document is printed from the print start position.
As a result, the document is printed on the paper with the same layout as that adjusted on the previous layout screen.

EFFECTS OF THE INVENTION According to the present invention, an operation of directly changing the display form of the relative display positional relationship between the display image of the document area range and the paper layout frame display image displayed on the display screen is performed. Just by changing the format data, the format data that determines the layout position of the document area on the print paper can be changed so as to match the changed display position relationship, and the operator does not have to be aware of the internal format data itself. The format can be changed to a desired format simply by designating on the display screen the display image of the display form itself of the arrangement position relation desired to be printed out.
