Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a data input device, and more particularly to an input device for an electronic computer suitable for improving data processing speed, reducing data input errors, and reducing operator fatigue.

[Background of the invention]

Conventional input devices only have keys for data input, and input guidance and input data require viewing the editing display of the host that is input from the input device.

For this reason, the person entering the data had to alternately look at the editing display, the input device's input keys, and in some cases the input slip sheet while inputting data, which caused physical and visual fatigue by taking pictures of one's head up, down, left and right. This has the disadvantage that it is easy to make incorrect inputs, and the input speed is slower than that of a typewriter type keyboard.

[Object of the Invention] An object of the present invention is to provide an input device for an electronic computer that can prevent erroneous input caused by physical and visual fatigue, which is a drawback of the prior art, and can increase the speed of data input.

[Summary of the invention]

The present invention eliminates the problem of input errors and data speed delays caused by alternately viewing the host-side editing display, input device, and input slip sheet. Is it also guidance?
Focusing on the fact that you only see the line where the cursor is, which indicates the data input point, and a few lines before and after it, we solved the above-mentioned cause by displaying the minimum necessary display on the same plane as the input key of the input device. It has been removed.

[Embodiments of the invention]

An embodiment of the present invention is shown in FIGS. 1 and 2 below.

This will be explained using FIG. 4, FIG. 5, and FIG. 6. In FIG. 1, an input guidance display 2 and a key switch 3 are arranged on the operation surface of an input device 1. At this time, FIG. 2 shows the editing display screen 4 on the host side that displays data input from the input device 1, and the input device 1 displaying the line with the cursor indicating the input point and the line before it. Input guidance display screen 5
Indicates the relationship between Generally, a cathode ray tube is used for the editing display button on the host side, and the rask scan method is used for the character display format. FIG. 4 is a diagram showing the relationship between this raster gyan, characters, and a cursor, and shows that horizontal scanning lines RO to R15 form one line of character display. Normally, horizontal scanning lines for character display and cursor display are determined in advance by the host, and in FIG. 4, characters are displayed at R3 to R9, and the cursor is displayed at R12. FIG. 5 is a signal time chart on the host side that displays data on the cathode ray tube of FIG. 4.

vS is a vertical synchronization signal, H8 is a horizontal synchronization signal, D is data actually displayed, and do to t are on the horizontal scanning line Rx.
In data is sent from the host. It should be noted that the horizontal synchronizing signal H3 occurs once every 1 horizontal scans, and in FIG. 4, the number of display lines is M.

The vertical synchronization signal vS1 period corresponding to one screen display has 16
There are ×M times of H8 signal generation.

Therefore, by monitoring the editing screen display signal from the host side with a circuit as shown in FIG. @6, it becomes possible to obtain a display as shown in FIG. 2 on the input guidance display 2 of the input device 10. That is, the H3 count counter 6 and the editing display line count counter 7 are reset to zero by the vertical synchronization signal vS. Vertical synchronization signal S
As soon as the signal disappears, data display starts on the first horizontal scanning line of the first row, and the H8 counter 6 counts up by the horizontal synchronizing signal H8 generated every horizontal scanning display.

At this time, the H3 counting counter 6 was adjusted to the number of horizontal scanning lines per line in FIG. 4, which is 16! If it is a hexadecimal counter, the editing display line counting counter 7 is counted up by the carry signal CY generated by the horizontal synchronizing signal H3 at the end of horizontal scanning of the 16-port, and the line number is changed. Incidentally, after the H8 counting counter 6 sends out the carry signal CY,
Reset yourself. Next, the horizontal scanning line R12 signal of the H3 counting counter 6, that is, the cursor display scanning line and the display data D of the editing display screen 4 are combined by an AND gate 8.
When the cursor reaches the line where the cursor is located, the condition of the AND gate 8 is satisfied, and the data set input terminal S of the cursor display line storage register 9 is connected to the AND gate 8.
A signal is input from the 1-editing display line counting counter 70 line number data is taken in and stored from the DATA terminal, and continues to be stored until the next signal is input to the S terminal.

Also, the output of the cursor display line storage register 9 is input to the adder 1.
When inputted to the 00A terminal, the value added with the coefficient of the S terminal, that is, the data of minus 1 in FIG. 6, that is, the output of the adder 1o becomes the row number data of the row before the cursor display row number de i. The outputs of this cursor display row storage register 9 and adder 10 are outputted by σR gate 11.
By taking R, the output of the OR gate 11 is the OR of the cursor display line and the line number of the line before the cursor display line.
It becomes data.

Therefore, the output data of the OR gate 11, the output of the editing display row counter indicating the row number currently displaying data on the editing display, and the display display data D are ANDed by the AND gate 1211? : If you enter
The output CLD is such that only the display data of the cursor display line or the display data of the line before the cursor display line of the editing display screen 4 is sequentially output, and this output CLD is used to form the input guidance display screen 5. I can do it.

Note that the input guidance display 2 is as follows.

When using a display that displays under the same conditions as the editing display of the host, it is sufficient to monitor the horizontal synchronization signal H8 and vertical synchronization signal vS. In addition, in the case of a display with different display conditions, the CLD is imported into the display memory of the input guidance display 2 during the CLD input period, and the lines other than the cursor display line and the line before the cursor display line are imported into the editing display screen during the CLD invalid period. It is also possible to display the input guidance display 2 only while the input guidance display 4 is scanning.

In addition, if the power is turned on on the 1 editing display screen 4 and the cursor position is moved by a line feed, the correct display will appear on the input guidance display screen 5 after a delay of 1 frame on the 5 editing display screen 4. , generally the CRT display for electronic computers is 50 to 60.
The delay per frame is 17 to 20 milliseconds, which is small and poses no problem in practical use.

In the above description, the adder 10 and OR gate 11 in FIG. 6 may be deleted and the output of the cursor display row storage register 9 may be directly connected to the AND gate 12.

Another embodiment will be explained with reference to FIGS. 3 and 7.

Figure @3 shows the editing display screen 4 on the host side and the input guidance display screen 5 of the input device 1.1 that displays the input guidance line and cursor display line.
Indicates the relationship between Assuming that the editing display on the host side is similar to (a).

The difference between FIG. 7 and FIG. 6 is that what was the adder 10 in FIG. 6 is now data G.DATA indicating the guidance row number from the host in FIG. As a result, in FIG. 7, the OR gate 11 becomes an OR of the output of the cursor display line storage register 9 and the data from the host indicating the guidance line/bar, and the output of the AND gate 12 becomes the output of the data instructed by the host. Only the display data of the guidance line and cursor display line of the editing display screen 4 are sequentially output, and the input guidance display screen 5 of FIG. 3 is formed using this output CLD.

Still other embodiments will be described with reference to FIGS. 8, 9, and 10. 8, the difference from FIG. 1 is that a guidance line setting switch 14 is added to the input device 1. As a result, as shown in the input guidance display screen 5 of FIG. 10, the operator of the input device 1 can set a desired line, and the input guidance display screen 5 can be displayed together with the cursor display line.

A means for realizing this is shown in FIG. Assuming that the editing display on the host side is the same as in (a), the difference between FIG. 9 and FIG. 6 is that in FIG.
In the figure, only the guidance row setting switch 14 is shown. As a result, in FIG. 9, the OR gate 11
In this case, the output of the cursor display line storage register 9 and the output of the guidance line setting switch 14 are ORed, and the output of the AND gate 12 is the cursor display line of the editing display screen 4 and the guidance specified by the guidance line setting switch 14. Only the row display data is output in the display order on the one editing display screen 4.

By using the output CLD of the AND gate 12, the input guidance display screen 5 shown in FIG. 10 is formed.

With the above implementation means, the operator of the input device 1 only needs to look at the key switch 3 of the input device 1 and the input guidance display screen 2 in the same plane during normal input. There is no need to view the editing display screen 4 on the host side for each input.

As a result, the operator of the input device 1 is freed from the action of tilting his head downward, that is, the action of alternately looking at the input operation surface, the editing display, and the screen.

Input errors due to fatigue are also reduced. Input speed will also improve. Especially like multi-item input devices.

A key switch with multiple meanings is highly effective because it cannot be blinded.

Furthermore, considering the case of inputting slip data, the operator of the input device 1 inputs the slip and the input device.

There is no need to look at the editing display screen and three other places, and if the slip is placed on the left and right sides of the operation surface of the input device 1, the operator's eyes only need to move left and right, which is ergonomically friendly. In comparison, the sensitivity is better than that of vertical vision,
With less fatigue and fewer errors, data can be entered correctly and quickly.

Further, since the input guidance display screen 5 on the input device displays only a few lines including the input points of the one editing display screen 4, it has the effect of strongly appealing to data inputters.

This also has the effect of reducing fatigue compared to when the entire editing screen is visible.

Furthermore, by adding a scale indicating data input position coordinates around the input guidance display 2, or by displaying a scale similar to the one described above on the input guidance display screen itself, data input can be easily understood when used as a word processor. can do.

〔Effect of the invention〕

According to the present invention, several lines related to the line where the cursor indicating the input point is located are displayed on the operation surface of the input device, so that the data inputter can view the editing screen of the host and the operation surface of the input device. There is no need to look at the input device alternately; it is only necessary to look at the operation surface of the input device. Therefore, the data inputter can input data quickly and correctly with less physical and visual fatigue.
