Abstract

PURPOSE:To allow a transparent operation part to execute an instruction displayed on a screen, miniaturize a device panel and to simplify operation by displaying an operation key necessary for NC operation on the screen of a CRT device and arranging the transparent operation part for executing the instruction of the operation key on a position corresponding to the operation key arranged in the front of the CRT screen. CONSTITUTION:The display of various input keys relating to respective pictures are previously programmed in various pictures displayed on the CRT 1 and plural light emitting elements 4 are respectively arranged on the upper and left sides of a transparent protection cover 3 formed in the front of the screen of the CRT 1. On the other hand, light receiving elements 5 are arranged on the lower and right sides of the cover 3 oppositely to the light emitting element 4 and an optical axis matrix is constituted on the intersecting points of the light emitting and light receiving elements 4, 5 by means of invisible light. The intersecting points are allowed to correspond to various input key displays displayed on respective pictures of the CRT 1. A displayed input is decoded by a decoding circuit 7 to execute the inputted instruction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an NC device, and particularly to a key operation portion thereof.

[Conventional technology]

FIG. 2 is a diagram showing, for example, the key operation part of a conventional NC device. In the figure, (1) is a CR displaying NC information.
T, (2) is the operation keyboard for switching the screen of CRT (1) or inputting data, (3) is the CRT (1)
It is a transparent protective cover installed on the front of the

Next, the operation will be explained. When operating the NC device,
The information necessary for the operation is called up on the CRT (1) screen, the operator confirms the content displayed on the screen, and then
E T (1) The necessary keys on the keyboard (2) provided nearby are operated to input data corresponding to the display screen or to switch to another screen.

[Problem to be solved by the invention]

Since the conventional NCFi installation is configured as described above, when performing an operation using the keyboard (2), (, RT (1)
There were other problems, such as the need to alternately view and operate the display screen and the keyboard (2), which took time, and required space for the keyboard (2).

This invention has been made to solve the above-mentioned problems, and its object is to provide an NC device that allows keyboard operations to be performed in a short time and that requires less installation space.

[Means to solve the problem]

No% related to this invention! C) tT displays operation keys necessary for NC operation on its screen, and a transparent operation section provided on the front of the CRT screen at a position corresponding to the operation key to execute the command of the operation key. It is equipped with a transparent panel.

[for]

In this invention, the transparent operation section of the transparent panel provided in front of the CRT screen executes the commands of the operating keys displayed on the CRT screen.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (4)l;f is a light emitting element that emits invisible light, (may) is a light receiving element that receives invisible light emitted from light emitting element (4), and (6) is a light emitting element that emits invisible light from light emitting element (4). I
The control circuit (7) is a decoding circuit that performs decoding processing after detecting the light receiving state of the light receiving element (5).

Next, the operation will be explained. Various input keys related to each screen are programmed in advance on the various screens displayed on the OL(T (1).
1) For example, 10 light-emitting elements (4) are placed on the upper side of the transparent protective cover (3) provided on the front surface of the screen, and the same number of light-receiving elements (5) are placed on the lower side at positions facing the light-emitting elements (5). will be established. Furthermore, eight light-emitting elements (4) are provided on the left side of the transparent protective cover (3), and the same number of light-receiving elements (5) are provided on the right side at positions facing the light-emitting elements (4). An optical axis matrix is formed by the invisible light rays emitted by the light emitting element (4) provided on the upper side of the protective cover (3) and the light emitting element (4) provided on the left side thereof.

Here, the intersection of the above optical axis matrix (in this case 8Xl
O=80 intersections) are made to correspond to various input key displays displayed on each screen of the CRT (1). Now,
If you select, for example, 1 machining input, which is displayed on the screen displayed on the CRT (1) surface, as shown in Figure 1, the screen displayed on the CRT (1) surface is Touch the transparent protective cover (3) part that corresponds to the part 1 with your finger. This operation prevents the light receiving element (5) on the x1 axis and the light receiving element (5) on the \3 axis from receiving light. The decoding circuit (7) detecting this state outputs the signal to the above-mentioned 1 processing input' signal output terminal. Below, select various functions, input data, or use the CRT. This allows you to freely exercise its functions.

Note that in the above embodiment, the light emitting elements (4) provided with the cloudy top and left sides ζ are always emitted, but even if they are sequentially scanned at predetermined time intervals, the same effect as in the above embodiment can be obtained. play.

Further, in the above embodiment, the light emitting element (4) and the light receiving element (5) constituted the optical axis matrix, but the matrix may also be constituted by using magnetomotive sound waves or electromagnetic waves. Even if the matrix is configured by pasting transparent matrix sheet keys, the same effects as in the above embodiment can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, by touching the part of the transparent protective cover provided on the front surface of the CRT screen that corresponds to the input key display section displayed on the CRT screen, the function indicated by the input key is executed. I configured it so that
This has the effect of making it easier to manually operate the keys, saving time, and eliminating the need for installation space for the keyboard, resulting in miniaturization.
