Abstract

PURPOSE:To improve the operability by providing a selecting logic part which determines a picture in accordance with input to load and execute a corresponding picture file, a picture management table for picture determination, a picture file consisting of picture data and display logic, and a CRT display part. CONSTITUTION:When a key is operated on a key input part 1, a selecting logic part 2 discriminates the operated key to determine the movement direction on a picture management table 3 in accordance with the present position on the picture management table 3 mounted on a CRT display device and contents of the key. For example, when 'picture down' is selected on the picture of present number '100' in the picture management table 3, picture number '200' is obtained as data. The selecting logic part 2 loads pertinent picture data and display logic from a picture file 4 on the basis of the picture number obtained by this operation and outputs execution results to a CRT display part 5. Thus, pictures are selected only by an easy key operation (for example, arrow keys).

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a CRT display system, and more particularly to a CRT screen selection system that allows a specific screen to be selected from a large number of screens with a simple operation.

(Prior art) Conventionally, this type of display device has limited display space, so it is often layered and divided, and in order to select a specific screen from a large number of screens, (1) menu selection is required. ,
(2) Screen name or screen number input, or a combination thereof. In such a method, the operator must either return to the menu screen each time a selection is made, memorize the correspondence between screen contents and screen names/numbers, or prepare a list and have the operator refer to it. It was either done or done.

(Problems to be Solved by the Invention) In the conventional CRT screen selection method described above, in the case of a large-scale screen configuration, it is necessary to call up a submenu from the menu, which complicates the procedure and makes it difficult to change the screen configuration. It had the disadvantage of not being able to respond flexibly to changes, additions, and deletions. In addition, for random access by screen name and screen number, the screen name corresponds to the screen content and the keyword for selection.

There are disadvantages in that it is necessary to remember the number or index the list, and the number of key inputs for selection increases.

(Means for Solving the Problems) The CRT screen selection method of the present invention identifies a key input section for selecting a screen and the input of the key input section, and determines the screen according to the result. It is composed of a selection logic section that loads and executes a screen file to be displayed, a screen management table for making internal decisions, a screen file consisting of screen data and display logic, and a CRT display section, and has a hierarchical structure of the screen. is written in advance in a screen management table, and this screen management table is searched in response to key inputs, so that screen selection can be performed only by key operations.

(Example) Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a CRT display device according to an embodiment of the present invention, FIG. 2 is a diagram schematically showing an example of a screen configuration, and FIG.
The figure shows an example of a screen management table according to the screen configuration shown in FIG. 2.

The CR'l' display device according to the present invention, as shown in FIG. be done. In FIG. 2, in response to the direction of screen movement indicated by the arrow shown in the figure, the key input section 1 is used to move the
"Down" key, "Screen left/right" keys used for horizontal movement within the same hierarchy.

Also provided are "page up/down" keys used to move pages within the same type. When one of the keys mentioned above is operated on the key input section 1, the selection logic section 2 identifies the operated key, and based on the current position on the screen management table 3 mounted on the CRT display device and the contents of the key. The screen management table 3 that determines the movement direction on the screen management table 3 has a configuration as shown in FIG.
If you select "lower part of the screen" on the "100" screen, the screen number "200" will be obtained as data.Based on the screen number obtained by the operation such as 0 or more, the selection logic unit 2 selects the screen file 4. The corresponding screen data and display logic are loaded from the CRT display section 5, and the execution results are output to the CRT display section 5.

(Effects of the Invention) As explained above, the present invention enables screen selection by using a screen movement direction specifying key for screen selection and a function to search a screen management table that describes the hierarchical structure of the screen according to key input. This can only be done with simple keystrokes (e.g. arrow keys). Furthermore, even if the screen configuration or screen number is not memorized accurately, the user can easily reach the target screen by operating the keys several times. Furthermore, the screen configuration can be changed by only partially changing the screen management table, which has the effect of improving maintainability.
