Abstract

PROBLEM TO BE SOLVED: To easily edit document while watching a reference document by separately providing a display part for reference document and a display part for editing document. SOLUTION: A CPU 1 writes data into a display memory for displacing the reference document registered on a hard disk 4 and the editing document to be newly prepared on a display part 6. At such a time, when the reference document and the editing document are simultaneously displayed, their respective display areas are made narrow and editing gets hard. Therefore, the documents are displayed by a multiwindow system for displaying them while overlapping the respective display areas and alternately switching any one of reference document and editing document on the fore side and the other document on the rear side (hiding the overlapped areas with the indication on the fore side) as needed. In the state of switching the reference document to the fore side, an operator presses a certain specified key on a keyboard 2. Through this operation, the CPU 1 executes data transfer from the display memory 7 to a display memory 10.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an information processing device and a display device.

[0002]

2. Description of the Related Art An information processing apparatus such as a word processor creates and edits a document, prints the document, and saves the document as necessary. However, in editing, there are many opportunities to refer to another document. For this reason, the document to be referred to has been printed and referenced on paper. However, it takes time to print and obtain the document, and there is a waste that the paper is unnecessary after the reference. On the other hand, in recent years, a reference document and an edited document can be simultaneously displayed and edited by using a multi-window system capable of simultaneously displaying a plurality of documents on a display unit. When the reference document and the edited document are displayed at the same time, each display area is narrowed, so that it is difficult to reference and edit. Therefore, the display areas are superimposed, and the reference document or the edited document is displayed in the foreground when necessary, and the other area is alternately displayed in the rear side (the superimposed area is hidden by the foreground display). Can be. However, there has been a trouble that the operator switches the display and memorizes the backed document by the operator.

[0003] This problem also occurs in the case of an information processing device such as a personal computer when performing an operation while displaying a help function.

[0004] These prior arts are disclosed in JP-A-5-279.
No. 38, “Multi-window display device”. However, the present invention is devised to minimize the overlapping portion, but the overlapping remains, so that the trouble of the operator could not be eliminated.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an information processing apparatus for editing a document, which eliminates the above-mentioned switching of display and troublesome storage of an operator and facilitates editing while viewing a reference document. Is to provide.

[0006]

According to the present invention, there is provided a display memory for storing data of a document to be displayed, a display for displaying the document based on the data of the display memory, and a display system for displaying the data of the display memory on the display. A display control unit for converting data according to the data, a second display memory for copying and storing the value of the display memory, a second display unit for displaying a document based on the data in the second display memory, A second display control unit that converts data in accordance with the display method of the second display unit; and a control unit that transfers data from the display memory to the second display memory.

In order to display a plurality of reference documents instead of one, a plurality of sets of the second display memory, the second display section and the second display control section are provided instead of one set. Control means for transferring data to the storage device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. The CPU 1 is a central processing unit that controls the entire information processing device. The keyboard 2 is an input unit of the information processing device for giving instructions such as inputting characters and printing. Main memory 3 is C
This is a storage unit for temporarily storing work data and the like of PU1. The hard disk 4 is a storage device for registering a document editing program and an edited document. The floppy disk 5 is a storage device in which a disk for registering an edited document or upgrading a document editing program can be replaced. The display 6 is a CRT
And a display such as a liquid crystal display. The display memory 7 is a memory written by the CPU 1 for displaying on the display unit 6. The display control unit 8 is a control unit that converts data in the display memory 7 according to the display method of the display unit 6.
The display unit 9 is a display such as a CRT or a liquid crystal. The display memory 10 is a memory written by the CPU 1 for displaying on the display unit 9. The display control unit 11 is a control unit that converts data in the display memory 7 according to the display method of the display unit 6.

Next, the operation will be described. FIG. 2 is a processing flowchart of one embodiment of the present invention. The CPU 1 writes data in the display memory 7 to display the reference document registered in the hard disk 4 and the newly created edited document on the display unit 6. At this time, if the reference document and the edited document are displayed at the same time, the respective display areas become narrower and editing becomes difficult, so that the respective display areas are superimposed, and the reference document or the edited document is brought to the foreground when necessary, and the other is displayed. The image is displayed in a multi-window system that can be alternately displayed on the rear surface (the overlapped area is hidden by the front display). The operator presses a specific key on the keyboard 2 with the reference document switched to the front. With this operation, the CPU 1 executes data transfer from the display memory 7 to the display memory 10. By this transfer, the display unit 9 has the same display as the display unit 6. Next, the operator switches the display on the display unit 6 so that the edited document is at the front. Thus, the reference document and the edited document are displayed on the display unit 9 and the display unit 6, respectively, so that the user can easily perform editing while viewing the reference document.

FIG. 3 is a block diagram showing a second embodiment of the present invention. The port 12 is a port for sending data from the information processing device to the display device. 2nd port 1
Reference numeral 3 denotes a port for receiving data from the information processing device to the display device. The second CPU 14, the second main memory 15, and the program memory 16 are a central processing unit and a storage unit that perform processing performed by the CPU 1, the main memory 2, and the program of the hard disk 4 on the display control unit instead. . With this configuration, the display device can be configured as a device independent of the information processing device. Also,
The port 12 includes a parallel port, a serial port, and a SCSI that can be provided as standard or additional equipment in the information processing apparatus.
(Small computer system interface) If a port or the like is used, the object of the present invention can be achieved by adding software without changing the hardware of the information processing apparatus. Since SCSI can connect up to seven peripheral devices, if a display device is identified using the SCSI ID number, up to seven display devices can be connected.
Seven reference documents can be referred to at the same time.

[0011]

According to the present invention, when editing a document while viewing the reference document, the display unit for the reference document and the display unit for the edited document are provided separately, so that the same display unit is used. Compared to displaying the document and the edited document at the same time,
Since the switching of the display and the troublesome storage of the operator can be eliminated, the editing can be performed easily.
