Abstract

PURPOSE:To allow the easy reference and utilization of the data which is not currently displayed on a main display device by storing the image data on the arbitrary screen of the main display device and displaying the image data on an auxiliary display device at need. CONSTITUTION:An image memory 19 of an image data memory device 13 stores the image data from a data processor 11 by each screen. A memory control section 20 controls the input of the image data to the image memory 19. A display control section 21 controls the output of the image data stored in the image memory 19. The auxiliary display device 14 of controller 10 displays the image data stored in the image memory 19 by each screen. The necessary data on the screen of the main display device 12 is stored into the image memory 19 by each screen by pressing a save switch 23. Switches 24, 25 for displaying the next screen or previous screen are then pushed to display the data desired to be referenced on the auxiliary display device 14 by each screen. The easy referencing and utilizing of the data which is currently not displayed on the main display device are possible in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that stores image data from a data processing device and displays it screen by screen on an auxiliary display device different from a main display device.

[Prior Art] When developing or designing a program for a data processing device such as a personal computer or a microcomputer,
You may want to refer to data in the same file that is not displayed on the main display device connected to this data processing device, or you may wish to use or refer to data in a file other than the one currently being edited. .

Conventionally, in the former case, the user scrolls the screen to display the necessary data on the main display device, and then prints it out or transcribes it in a memo.

In the latter case, you can either load another file into the file you are currently creating and display the necessary data on the main display device, or you can save the file you are currently creating and then start the other file again. Necessary data is displayed on the main display device, printed out, or transcribed into a memo.

[Problems to be Solved by the Invention] The method of printing out data that needs to be referenced or copying it into a memo requires extra effort and has the problem of not being able to quickly develop or design a program.

Furthermore, the method of reading another file has the problem that it is cumbersome to switch between the currently created file and another file on the main display device, and it is difficult to see the data of both files when they are displayed at the same time.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image data storage and display device that allows data not currently displayed on a main display device to be easily referenced and utilized.

[Means for Solving the Problems] In order to achieve the above objects, the present invention provides a device for storing and displaying image data output from a data processing device to a main display device, and is characterized by the above-mentioned features. an image memory that stores image data from a data processing device for each screen; a memory control unit that controls input of image data to the image memory; and a display control unit that controls output of the image data stored in the image memory. an image data storage device including: an auxiliary display device capable of displaying the image data stored in the image memory on a screen-by-screen basis; a save switch that controls the memory control section; and a next screen that controls the display control section. - A control device including a front screen display switch is provided.

[Operation] Press the save switch to store the necessary image data on the screen of the main display device in the image memory for each screen, then press the next screen or previous screen display switch to save the data you want to refer to the auxiliary display device for each screen. to be displayed.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIG. 1, an image data storage and display device 10 of the present invention is a device that stores and displays image data output from a data processing device 11 to a main display device 12. This storage display device 10 includes an image data storage device 13, an auxiliary display device 14, and a control device 16.

The image data storage device 13 has an input interface 17, C
It includes a PU 18, an image memory 19, a memory control section 20, a display control section 21, and an output interface 22. The image memory 19 is connected to the main display device 1 as shown in FIG.
It has a capacity that can store image data equivalent to 10 screens of 2. The image memory 19 uses the memory control section 20 to store the image data from the data processing device 11 for each screen as shown in FIG. 2, and the display control section 21 outputs the stored image data for each screen.

The control device 16 includes a save switch 23 that controls the memory control section 20 of the storage device 13, and a next screen display switch 24 and a previous screen display switch 25 that control the display control section 21.

The display control unit 11a of the data processing device 1l is connected to the main display device 12 via an output interface 11b, and is also connected to the input interface 17 of the image data storage device 13.

A save switch 23, a next screen display switch 24, and a previous screen display switch 25 of the control device 16 are connected to this interface 17.

An auxiliary display device 14 and a printer 26 are connected to the output interface 22 of the storage device 3. The auxiliary display device 14 is capable of displaying the image data output from the storage device 13 in a multi-divided manner for each screen of the main display device l2.

A method of using such a structured image data storage/display device will be described.

First, when developing a program, if you want to store the image data displayed on the main display device 12 in the storage device 13, press the save switch 23 and use the memory control section 20 to save the image data for each screen on the main display device 12. Then, the image is stored in the image memory 19 as shown in FIG. To store the image data of the next screen on the display device 12, press a roll-up switch (not shown) on the data processing device 11 to switch to a new screen, and then press down on the save switch 23.

Next, when referring to data of the same file that is not displayed on the main display device 12, the auxiliary display device 14 is caused to display the image data stored in the image memory 19 of the storage device 13.

If necessary, the user presses the next screen display switch 24 or the previous screen display switch 25 to change the screen of the auxiliary display device 14 and search for a screen containing data to be referenced.

When it is desired to store image data in an amount exceeding the storage capacity of the image memory 19, the hard copy of the auxiliary display device 14 is first sent to the printer 26 via the output interface 22.
After printing out the image data, the image data is newly stored in the image memory 19.

[Effects of the Invention] As described above, according to the present invention, image data on any screen of the main display device can be stored and easily displayed on the auxiliary display device as needed. By referring to the auxiliary display device, you can easily use data that is not displayed on the main display device without printing it out or transcribing it in a memo, increasing the efficiency of program development or design. can be improved.
