Abstract

PURPOSE:To use fully the entire part of the screen of a CRT display device in accordance with its original purpose, by securing such a constitution where the independent display is performed for the functions of software keys through a liquid crystal display device. CONSTITUTION:The functions of the software keys are displayed by a liquid crystal display device 4. For instance, the software key function is displayed by the device 4 for the purpose of the #1 application screen 11 when the #1 screen 8 for CRT display is displayed. Thus an operator operates the desired key with reference to the display contents of the working device 4 when the operator tries to operate an input key 5. So is with the display of the #2 application screen 12. Thus it is not needed to use several lower rows of the CRT display screen to display the functional of the software keys like a conventional case. As a result, the entire part of the screen can be used for display of application and therefore the pictures can be displayed in large sizes.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device with a software key function for a driving operation panel with a CRT display device.

[Conventional technology]

Conventionally, the input keys on the operation panel with CRT display device were:
As a measure to improve the functionality of the limited number of keys, functions can be set and expanded for each CRT screen. Functions of software keys are displayed using several lines at the bottom of the CRT screen. As a result, the display area of the original application display screen naturally became narrower, making it impossible to utilize the CRT screen sufficiently widely.

Here, the software key functions related to the conventional operation panel with CRT display device will be explained below with reference to FIGS. 4 to 6.

Figure 4 shows a conventional software key display device. In the figure, +8+ to QQI are CRT display devices H

In the external view of the driving operation panel with T display device, (7) is the driving operation panel.

Next, the functions, usage, display, etc. of the software keys will be explained.

A software key is a limited number of input keys (

(This is a key to which the function of the input key (5) can be assigned to correspond to the screen of 31, and the method of assignment is not directly related to the present invention, so it will be omitted.

Software key castle 1 assigned in this way
, H are displayed using, for example, the lower few lines of the A1 application software function display (14) and RT display screen for the A1 application screen υυ, as shown in FIG. Therefore, the operator looks at the A1 application software key function display a4 displayed on the A1 application screen (Lυ) and performs the necessary key operations.

Similarly, when the Ya2 application screen (Iz) is displayed, the function of the input key (5) will be the function displayed on the Ya2 application software key function display α9, so
Perform the necessary key operations for each display.

Here, although FIG. 5 is not directly related to the explanation of the software keys, it shows a general internal block configuration of a driving operation panel with a CRT display device.

Figure 6 similarly shows the CRT display device (3) and input keys (5).
) is shown below.

[Problem that the invention seeks to solve]

Since the conventional software key function display device is configured as described above, the A1 application screen α9 to 7%
n, application screen (display space of 13 is A
1. Application software key function display a
◇~A n, due to the application software key function display αe, there were problems such as the inability to display satisfactorily in narrow spaces, especially when graphic displays such as plants were displayed on the application screen. . In addition, when operating important input keys,
As shown in the figure, when the function display position of the software key is separated from the input key, there are problems such as it is very difficult to illuminate and is inconvenient to operate.

This invention was made to solve the above-mentioned problems, and it has a software key function that allows the application display of the CRT display device to fill the original CRT display space, and also eliminates the inconvenience of operation such as difficulty in viewing. The purpose is to provide an attached display device.

[Failure to solve the problem]

The function display position of the software unit according to the present invention is such that when a conventional CRT display device is used as the first display device, a flat display device such as a liquid crystal display device [4? The liquid crystal display device r (software) is arranged directly above the keys and displays the functions of the software keys.

[For production]

The software key function display in this invention is displayed on a liquid crystal display device (second display device).

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the same parts as in FIGS. 4 to 6 are designated by the same reference numerals. In FIG. ), (4) is a liquid crystal display controller (2nd) that displays the functions of the software keys;
display device).

In addition, FIG. 2 shows a liquid crystal display device (4) which is a feature of the present invention.
This is an external view of a driving operation panel with a CRT display device incorporating a CRT display device, (3) is a CRT display device, (4) is a liquid crystal display device,
(5) Input key 1 (7) is a driving operation panel.

Furthermore, FIG. 3 shows the mutual relationship between the CRT display device (3) (first display device) and the liquid crystal display device (4) that displays input keys (5) and software key functions.
4) is a liquid crystal display device, (5) is input key 1 (8) to a1
are application screens A1 to An, respectively.

Next, the operating functions will be explained. First, the functions of the software keys are displayed on the liquid crystal display device (4) shown in FIGS. 1 and 2. The display operation will be explained with reference to FIG.

The display of the functions of the software keys explained in the prior art in FIG. 3 is, for example, on the CRT display JlfA1 screen (8).
When displayed, the software key functions for J161 application screen Qυ are displayed on the liquid crystal display (
4). Therefore, when the operator wants to sweep the waiting key (5), he looks at the contents displayed on the liquid crystal display device (4) and performs the necessary key operations. The same applies when the A2 application screen α2 is displayed.

As described above, according to the embodiment of the present invention, there is no need to use the lower few lines of the CRT display screen to display the functions of software keys as in the past, and the entire screen can be used for application display. Can be used in large quantities.

In the above embodiment, the display contents of the liquid crystal display device (4) are limited to the display of the functions of the software keys. It can also be used for switching between displaying software key functions and displaying the force and guidance for what the operator should do next.

〔Effect of the invention〕

As described above, according to the present invention, the functions of the software keys are borrowed so that they can be displayed independently by the liquid crystal display device, so that the entire screen of the CRT display device can be fully displayed as intended. It can be used.

Furthermore, since the liquid crystal display device can be installed directly above the input keys, it is very easy to see during operation and helps prevent erroneous operation when operating the input keys.
