Abstract

PURPOSE:To facilitate setting items and make quick response possible by constituting a keyboard of a numerical control device with a pressure-sensitive transparent film and a CRT where keys are displayed as a picture. CONSTITUTION:The numerical control device is provided with an operation board 1 which is used to input data by a user and to obtain information from display contents, and the operation board 1 is provided with a CRT2 for display and a pressure-sensitive transparent film 5, and a CRT7 for operation is provided at the rear of the operation board 1. Depressed coordinate positions of the transparent film 5 are converted to key information by an A/D converter 6. A key arrangement chart is displayed on the CRT7 for operation when a power switch is closed, and key information corresponding to said key arrangement are transmitted to the numerical control device in accordance with position information of depressed positions when the transparent film 5 on the CRT7 is depressed. If a change key is operated to rewrite said key arrangement chart, the display picture is changed, and another item can be inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input operation section for inputting data from an operation board.

[Conventional technology]

A conventional numerical control device of this type is shown in FIG.

In the figure, (1) is an operation board through which the user inputs data into the numerical control device A or obtains information from self-answering by displaying 0, and a display device described later is installed. (2
1 is a display CRT installed on this operation board (1) to display information; The keyboard is equipped with a plurality of keys. (4) is a switch for turning on and off the source of the ridge control device A.

The conventional e-value 1ttlJ sea bream apparatus 1A is configured as described above.

The user can operate the entire operation board (1).

Sends and receives information to and from the numerical control device A. First, when the user turns on the #It source switch (41'kr on), a title screen appears on the CRT (2).Next, the user presses an appropriate key on the keyboard (3) to turn on the 0 The screen changes and the process goes to numerical control device A. Then, when device A needs more data, it displays a data request message on the CRT (21) and sends a message to the user. When attempting to input data, the process is advanced by pressing a predetermined key on the keyboard (3).

[Zhao point that the invention is trying to solve]

Since the conventional numeric side (2) device kL is configured as described above, the key information data sent by the user to the numeric side device is retrieved by characters, symbols, etc. written on the keyboard. LIMITED.

In addition, when all the characters, symbols, etc. on the keyboard and keyboard were to be replaced for improvement, etc., the problem was that it would take a huge amount of time and money.

This invention was made in order to solve the above-mentioned problems, and there are no restrictions on the types of characters and symbols on the keys on the keyboard. The object is to obtain a ridge 11N control device that can be changed.

[Problem t-Means for solving]

The number IIN control device according to the present invention includes a CRT for operation in which all characters, symbols, etc. can be easily changed, and a transparent CRT that is arranged on the image display surface of the CRT for operation and outputs position information of pressed coordinates. A membrane, and A that converts the position information into key information.
It is equipped with a D converter.

[Effect]

The numerical value side (to) device in this invention is the image 11! of the CRT for operation. The display corresponds to the characters, symbols, etc. of a conventional keyboard, and the pressure-sensitive transparent membrane corresponds to the keys. By changing the displayed self-answer on the lIm display, characters, symbols, etc. can be easily changed, so an operation board with a degree of freedom of t-wait is possible.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. gt
In the figure, (11, (2), (41) are exactly the same as the conventional device mentioned above, and t5) is a pressure-sensitive transparent E94.
It is a membrane. FIG. 2 is a schematic perspective view showing the features of the present invention. 5
) pressed coordinate position [t-key information changes to A /
D converter.

(7) is an operation character display (hereinafter referred to as operation CRT) placed behind the transparent film (5) to display all symbols, characters, etc.

When a user is in the numerical control device A configured as described above and turns on the power switch (41t-r on).

CRT for operation (71 is the initial key layout diagram, -
tc is shown. Next, the user selects an appropriate location on the operating CRT (71) according to the key arrangement diagram displayed in the image and presses the transparent film (5) on the operating CRT (71).The pressed position information t-A/ By converting the D converter (61) into key information and transmitting the converted key information to the e-value opening WJ device, the same processing as the conventional device can be performed. Here, when changing the 9 display screen By performing the key operation of the change key, the key arrangement diagram displayed in the image of ORT (71) is changed, and the user can perform the operation based on the changed screen. , it becomes possible to input other items.

In addition, in the above embodiment, the operation cRT (Tit-character display) or a graphic display (in this case, the key function can be represented by a pattern) improves the operability. There is an effect.

〔Effect of the invention〕

As mentioned above, according to this invention! ! The keyboard of the value control device is equipped with a pressure-sensitive transparent screen.
Since the key display is arranged in parallel with the CRT that displays images, these arrangements make it possible to set more than twice the number of items compared to conventional keyboards, and it is also possible to change characters, symbols, etc. You can see the effect of being able to respond quickly to any situation.
