Description of the Related Art Conventionally, a Japanese word processor as an information processing apparatus generally inputs document information such as characters and ruled lines by a user of the apparatus operating a key on a keyboard and controls the document information. A document is created by being controlled by the means and displayed on the display.

Further, the Japanese word processor as described above displays the document information on each print sheet by displaying the document information as a print image for each size of the print sheet on the display screen of the display. It can be checked roughly.

[0004]

However, since the display image on the display screen has a constant display magnification in the conventional print image of the document information as described above, for example, a print sheet such as a B4 format print sheet is used. If the size is large, the print image cannot be displayed on one screen of the display, and the screen can be displayed by pressing the function key on the keyboard corresponding to the top, bottom, right, or left edge of the print paper. There is a problem that the print image must be partially confirmed by scrolling.

[0005]

In order to solve the above-mentioned problems, the information processing apparatus of the present invention provides document information such as characters and ruled lines which are input by the input means and controlled by the control means to each printing sheet. The following measures are taken in the information processing apparatus that displays a print image for each size on the display screen of the display unit.

That is, the control means calculates the reduction rate of the document information according to the size of each printing sheet and displays the print image of the document information on one screen of the display means.

[0007]

According to the above construction, the control means for controlling the document information such as characters and ruled lines displays the print image of the document information by calculating the reduction rate of the document information according to the size of each printing sheet. It is designed to be displayed on one screen of the means. For this reason, the document information can be displayed as a print image on one screen regardless of the print paper size set in any format, so that the user of the device can check the print state of the document information at a glance. It is possible to improve work efficiency.

The recording unit 3 includes a ROM (Read Only Memory) 4 storing various programs and data, and a RAM (Random memory) including a scroll start position storage area, a document information storage area, a display mode storage area, and the like. Access Mem
ory) 5.

Further, the CPU 2 includes a keyboard 6 as an input means for inputting document information by a key operation of a user of the apparatus, a display 7 as a display means for displaying document information, and a recording medium (not shown). Disk device 8 for recording / reproducing document information in units of a certain disk
And a printer 9 for printing document information are connected to each other via a controller (not shown), and each operation of each of these components is controlled by the CPU 2.

Further, in the Japanese word processor of the present embodiment, the RAM 5 constituting the control means 1 is provided with a reduction ratio storage area for storing the reduction ratio of the document information, which will be described later, and also in the ROM 4. Stores a print image display processing program, an effective length table of each print paper size such as A4 format, and screen size information on the display screen of the display 7. Then, the print image display processing program calculates the reduction ratio of the document information within the print paper size that can be displayed on one screen of the display 7, based on the effective length of the formatted print paper size and the screen size information. At the same time, a compression pattern for displaying the document information is created according to the reduction ratio, so that the compression pattern is displayed as a print image on one screen of the display 7.

With the above arrangement, the print image display process by the print image display processing program of the Japanese word processor of this embodiment will be described below with reference to the flowchart of FIG.

First, the size of the formatted printing paper is checked (S1), and the effective length of the printing paper corresponding to this printing paper size is obtained from the effective length table in the ROM 4 (S2). Then, from the effective length of the printing paper obtained as described above and the screen size information stored in the ROM 4, the reduction ratio of the document information within the printing paper size that can be displayed on one screen of the display 7 is calculated. This reduction rate is calculated (S3), and this reduction rate is stored in the reduction rate storage area of the RAM 5.

Next, one line of data is created from the document information stored in the document information storage area of the RAM 5 and stored in a buffer (not shown) (S4). Then, for one line of data stored in the buffer in S4, a compression pattern for display is created for each character unit according to the reduction ratio obtained in S3 (S5), and is displayed on the display screen of the display 7. It is displayed (S6). Next, it is determined whether or not the display of the compression pattern corresponding to the data for one line in S6 is completed (S7), and if it is not completed, again,
While returning to S5, if the processing has been completed, the next line is expanded (S8).

Then, the above steps S4 to S8 are repeated until the last line of the document information (S9), and the compression pattern of the document information is displayed as a print image on one screen of the display 7.

As described above, the Japanese word processor according to this embodiment has the ROM 4 constituting the control means 1,
A print image display processing program is stored, and this print image display processing program is displayed on the display 7.
The reduction ratio of the document information within the print paper size that can be displayed on one screen is calculated, and the compression pattern for displaying the document information is created according to this reduction ratio, so that the above-mentioned compression pattern is used as a print image on the display 7. It is designed to be displayed on one screen.

Therefore, the print image of the document information can be displayed on one screen of the display 7 regardless of the print paper size set in any format, so that the printing state of the document information by the printer 9 can be seen at a glance.
