Abstract

PROBLEM TO BE SOLVED: To efficiently use a display by providing a means which automatically switches a screen to a longitudinally long style for handling of a longitudinally written document or a laterally long style for handling a laterally written document. SOLUTION: This device consists of a ROM 4 which stores a longitudinal/ lateral display switching program for a document, a RAM 5 which serves as a work area for executing the program, etc. Then a user selectively specifies form size, a form direction, a character string direction, multiple column, character size, character pitch, line pitch, etc., for a document to be prepared on the screen by using an electronic pen 2. The system generates a header part by writing data on the specification result of the user in an area for document data prepared on the RAM 5. Then the screen is switched to an input editing screen for the document and when lateral writing is specified as the character string direction of format setting, a normal document input editing screen which is used laterally long is obtained, but when longitudinal writing is specified, an editing screen for longitudinal writing is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a document creation and display device.

[0002]

2. Description of the Related Art Conventionally, a device for displaying an electronic document such as a word processor or a personal computer is used in a state in which a vertically or horizontally used direction is determined. And read or write a document while looking at the characters displayed on the screen.

[0003]

However, devices made on the premise of being carried around, such as a notebook personal computer or an electronic organizer, are small in size as a whole because of their portability. Many. Therefore, when a vertically written document is displayed on a horizontally long screen or a horizontally written document is displayed on a vertically long screen, the document must be read or written while scrolling up and down or left and right in particular.

[0004]

When reading and writing a document on a display screen having different vertical and horizontal lengths, the present apparatus uses a vertical screen when handling a vertically written document, and a screen when handling a horizontally written document. By providing a means to automatically switch to landscape mode, the number of scrolls in the column direction is reduced to reduce the user's operation burden, and when displaying the entire paper layout, the screen is also used when the paper is used horizontally. When the display is used horizontally or vertically, the screen is displayed vertically so that the display can be used efficiently.

FIG. 1 is a flowchart showing one embodiment of the present invention. The apparatus includes a processor 1 for controlling the system, an input unit 2 such as a tablet and pen and a keyboard, a storage unit 3 such as a memory card drive or a floppy disk for storing document data, and a ROM 4 for storing character fonts and system control programs. A RAM 5 serving as a work area for executing programs, a display device 6 for displaying documents and the like, and a display screen 6 such as a liquid crystal device also serving as a pen input tablet.
VR serving as a buffer for configuring document display data
It comprises a display unit 7 composed of an AM and a controller, and a system bus 8 connecting each device.

FIG. 2 is a flowchart of a program for switching between vertical and horizontal display of a document stored in the ROM 4, and FIG. 3 is an example of document data. The document data includes a data identification code indicating that the document is a document, a header portion in which information such as a paper size and a paper direction at the time of printing the document, and a character size are written, and a character code of an actual document. It consists of a text data part that is a list.

FIG. 4 shows a menu screen which is displayed first when the system is started. In this example, the screen is usually used horizontally in this manner. However, the same applies to a system which is normally used vertically. I can do it. First, when the user creates a document from scratch, in step 100, the user selects and designates creation of a new document from the menu in FIG. Then step 10
In step 02, an area for writing a new document on the RAM 5 is prepared. Then, in step 103, format setting is performed on a format setting screen as shown in FIG. 5 in order to create a header portion of the document data in FIG. The user uses the electronic pen 2 on the screen of FIG. 5 to specify the paper size and paper direction, the character string direction (vertical writing / horizontal writing), the column structure, the character size and the character pitch line pitch for the document to be created. To select. The system writes the data of the result specified by the user in the area of the document data prepared on the RAM 5 and creates a header portion. Then, the screen is switched to a document input / edit screen, and the work of creating document data composed of the text code strings shown in FIG. 3 is performed. When entering the document input / edit screen, if horizontal writing is designated in the character string direction of the format setting in step 105, the screen becomes a normal document input / edit screen using the screen as shown in FIG. Then, an editing screen for vertical writing as shown in FIG. 7 is displayed.

If the user wants to update a document that has been created instead of a new document, he or she selects document update in step 101. In step 104, the document to be updated specified by the user is read from the storage unit 3 and transferred to the RAM 5. In step 105, the character string direction of the header part is read, and the document input / edit screen is switched between vertical writing and horizontal writing.
View ready-made documents. Characters are displayed on the display device by sequentially transferring the character fonts indicated by the text code of the document data to the display buffer. As shown in FIG. 6 and FIG. 7, the display of characters is only different in the direction of characters between horizontal writing and vertical writing. In the case of horizontal writing, a font for horizontal writing may be used, and in the case of vertical writing, a font for vertical writing may be used, and the transfer position to the display buffer does not change. In the horizontal writing screen of FIG. 6, fonts for horizontal writing are displayed, and in the vertical writing screen of FIG. 7, the fonts for vertical writing are arranged in order from the upper left to the lower right of the display buffer, thereby switching the document display direction of the screen. Become. Since the part of the display buffer that can be displayed on the screen and the font that can be transferred to the display buffer is part of the entire document, the system uses the display buffer in accordance with the user's cursor operation and scroll bar operation. Change the displayed position or transfer a new font to the display buffer.

In the input and editing of characters, a character code obtained as a result of character recognition of the trajectory of the keyboard or the electronic pen is written in the text area of the document data in the RAM 5, or the already written text code is changed or deleted. Work. In this system, as shown in FIGS. 6 and 7, including the part for recognizing the trajectory of the line input with the pen as a character, the screen size of the document display area on the screen is not changed between vertical writing and horizontal writing. Switch direction. As shown in FIGS. 6 and 7, the coordinate system of the screen for pen input has the origin at the upper left of the screen. Therefore, assuming that the case of normal horizontal writing is (x, y) as shown in FIG.
Since y ′) can be replaced by x ′ = − y and y ′ = x, both coordinate calculation programs for character input can be used in common. When inputting a character code from the keyboard, there is no problem because such an area is not necessary. The system sets the display character font corresponding to the newly added text code or the rewritten text code of the document data in the RAM 5 in accordance with the user's document input / edit operation.
M4 is read out, the display position is calculated and transferred to the display buffer of the display unit 7, and characters are input to the screen or existing characters are changed. By switching the screen direction, the long side of the screen is used as the character string direction, and the number of scrolls in the character direction that must be performed for each line can be reduced.

During the input / edit operation of the document in step 110, there is a case where it is desired to view the layout of the entire sheet when the document is printed on the sheet. At this time, the user designates the layout display button shown in FIG. 6 or FIG. When the layout display is instructed, the system displays a reduced image when the document is printed on a sheet as shown in FIG. FIG. 9 is a flowchart of a layout display program. FIG. 8 is a display example of a layout screen in a case where the paper is used horizontally (a) and in a case where the paper is used vertically (b) in this system. As shown in FIG. 8, in the layout display, regardless of the horizontal writing and vertical writing of characters, the screen is used in portrait when the paper is used in portrait, and the screen is used in landscape when using the paper in landscape. When the layout instruction button is pressed, in step 201, the aspect ratio of the printing paper of the document data on the RAM 5 is calculated. From the calculation result, in step 202, a scale for displaying a frame indicating the size of the sheet is calculated. As shown in FIG. 8, this frame is reduced on a reduced scale such that either the short side or the long side of the screen is full length while maintaining the aspect ratio of the sheet. In step 203, the display position and the like are set in a normal (x, y) coordinate system for a horizontally long sheet, and in a (x ', y') coordinate system for a vertically long sheet, like the character input frame. An internal calculation program is set so as to calculate, a character position corresponding to the scale of the sheet is calculated in step 207, and a mark indicating a character or a display font which has been processed is transferred to the calculated character position and displayed. In step 208, the calculation display process is repeated for all the characters of the document to create a layout screen. By this switching, a more natural layout screen can be displayed.

[0011]

According to the present invention, when a document is created and edited using a relatively small display, the screen is set to be vertically long when handling a vertically written document, and the screen is set when handling a horizontally written document. By providing a means to automatically switch to landscape mode, the number of scrolls in the column direction is reduced to reduce the user's operation burden, and when displaying the entire paper layout, the screen is also used when the paper is used horizontally. When the screen is used horizontally or vertically, the screen is displayed vertically so that the screen can be used efficiently.
