Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to input and display devices. This input and display device has a screen and an input device associated therewith, and the screen and the input device are so dimensioned and adjacent to each other that the combination of the screen and the input device can be viewed by the operator without changing the line of sight. Will be placed.

2. Description of the Prior Art A conventionally known form of input and display device of this kind is EP-A-0 357.
No. 706. The device has a respective key bar or touch bar on one lateral edge and one on the upper edge of the screen. By operating these touch bars, the cursor can be moved to the position on the screen defined by the contact points (coordinates) on the two touch bars. This device is not only expensive, but also the adjustment accuracy that can be obtained is insufficient,
Especially if the screen is relatively small.

If the screen size is relatively small, its input and display devices are also known in the art. For example, a device for a sewing machine (DE-A-38 336
No. 05) or a seat movement control device in a car (US-A)
-4 853 697). In each of these cases, a group of adjacent keys is located below the screen. However, in a small-sized device required for a household device or a device panel or a device equivalent thereto, inaccurate operation or malfunction may occur due to the proximity of keys.

OBJECTS AND SUMMARY OF THE INVENTION It is an object of the present invention to provide an input operation that is accurate, self-explanatory, and easily reviewed, even when the screen and input device dimensions are small. This purpose is obtained by an input and display device, each of the input devices being provided on a respective side of the screen in the direction of moving the cursor. This device allows for accurate and unskilled actuation of the input keys. This is especially important if the operator has inadequate experience, such as when operating equipment that is used only occasionally, or if the registered data does not need to be changed often. For example, household sewing machines or sewing machines belong to this type of equipment. Therefore, it is preferable that the input keys are arranged on the periphery of the screen, that is, the input keys are arranged dispersedly apart from each other. In this way, such erroneous operations are prevented, yet the input keys and screen can be poorly overviewed as a single device, while each key moves the movable cursor depending on its position relative to the screen. Being associated with a direction, these keys are particularly logically arranged for easy understanding.

[0005]

The invention is explained in more detail below by taking examples and their applications.

The display device of FIG. 1 has an LCD screen composed of a square screen 1, for example, a matrix of 64 × 64 pixels, and having a side length of 3.5 cm. Directly adjacent each side of the screen are provided actuation keys 2-5. Each of the keys has an arrow symbol. The arrow symbols indicate the direction in which the cursor will move on the screen by activating the corresponding key.
These actuation keys can be push buttons, film keys, capacitive switches, or any other suitable input device, as well as other input keys described below. In the conventional manner, by intermittently or permanently pressing one of the keys 2-5 the cursor can be moved stepwise or virtually continuously in the required direction. Although the keys indicate the direction of cursor displacement in a logically understandable manner, it is always possible to observe a relatively small screen and keys 2-5 simultaneously. Therefore, since the keys 2 to 5 are arranged with a certain relative distance, and since their functions are immediately understandable and not confusing, accidental operation virtually does not occur.

As mentioned above, this input and display device can be fitted in particular to a sewing machine or an embroidery machine. Different additional functions of the input and display device can be selected by further keys. The selection of stitch length and stitch width is shown in FIG. In a practical way,
The stitch length is shown vertically and the stitch width is shown horizontally. To select the stitch width and stitch length, the cursor moves on the screen by vertical and horizontal displacement, eg to position A. In this case, the stitch length and stitch width are
Is displayed by the bar 7. Corresponding graduations can be displayed at the edges of the screen so that the effective stitch length value and effective stitch width value can be read, or can be displayed electronically on the screen from memory. As shown in FIG. 1, stitch length and stitch width adjustments can also be indicated by the light emitting lines corresponding to bars 6 and 7 or the rectangular frame of light emitting bars. For another adjustment, marked by point B, the entire rectangular surface is lightened, its width indicating the stitch width and its height indicating the stitch length. Alternatively, the two light emitting devices can be adjusted in the horizontal direction and the vertical direction, respectively, and their positions indicate the stitch width and the stitch length, respectively.

FIG. 2 shows the screen 1 at approximately its actual dimensions. Associated with this screen are additional action keys 8-17. These action keys are used to select a certain stitch pattern. That is, the stitch pattern stored in the electronic memory of the machine can be selected or modified as needed. Alternatively, any stitch pattern can be optionally entered and stored. The device of the key 8 makes it possible to select and display a pattern stored in the sewing machine or the embroidery machine, for example the pattern shown in FIG. Here, the size or magnification of the pattern can be selected by adjusting a cursor on the screen 1, for example. The individual stitches of this pattern can be stored by the device of the key 10. The entire pattern is stored by the device of the key 12 as soon as the entry of the individual stitches is completed. The sewing operation is started by key 13, and the pattern is repeated by the device of key 14. The sewing operation can be interrupted or stopped by the key 15 and optionally repeated in the sewing direction indicated by the arrow according to FIG. This pattern is key 16
It can be erased by the device. The key 17 is used to stop this stitch pattern operation, which causes the sewing machine to return to the regular sewing operation. With key 9,
To introduce any self-designed stitch pattern,
Make selections in advance. The required stitch pattern can be traced on the screen by the cursor.
The pattern is delineated by individual points, these individual points being stored in sequence by means of the key 10, or the light emitting connecting lines appearing between the individual points in sequence. The key 12 allows the arbitrarily introduced pattern to be stored in the memory of the sewing machine.

FIG. 3 also shows a screen 1 and keys 2 to 2.
5 and the associated action keys 18-20 are shown. When the key 18 is activated, a display appears on the screen 1 where certain selections for different fields can be made. This selection is performed by hovering over the requested field. For example, a decorative stitch pattern is presented in field 21, a buttonhole stitch pattern is presented in field 22, and a stitch pattern of letters and graphics is in field 2.
User programming is presented in field 2
4 is presented. After the stitch pattern of field 21 and the letter and graphic stitch pattern of field 23 have been selected and the key 18 has been repeatedly actuated,
One list according to FIG. 4 appears on screen 1. The screen 1 in this case displays either stitch patterns or letters and graphics, as shown in the two fields of FIG. By moving the cursor to the required field in this list, the corresponding stitch pattern is selected and confirmed by pressing the key 19. Thereby, the selected pattern is displayed on the screen, and it is possible to execute the change of the size and the magnification as described above. Then the sewing operation can be started. The selected sewing operation can be deleted by operating the key 20.

Optional corrections can also be made to the optional input of the pattern. For example, individual points can be deleted by activating two defined input keys 2-5 at the same time or by activating another correction key. For optional input of stitch patterns, models are also displayed on the screen and contoured to this pattern either by tracing them on the screen with water soluble colors or by attaching a transparency to the screen. The cursor is moved along and the data is registered in this way. In this case, the screen and the support material preferably have a matching grid.

Not only can the selected or registered stitch pattern or sewing mode be displayed on the screen, but also a programming or processing step, for example a sewing step, and thereafter on the screen in a suitable manner. Can be displayed.

FIG. 5 shows another possible application of the input device and the display device in connection with the input and display of time-dependent functions such as control of graphics or heat treatment. In this case, the screen displays time on the vertical axis and temperature on the horizontal axis. In the case of input, the cursor sequentially moves the fixed reference points 25 to 29. At the same time, the points are registered by the confirmation key. The screen then displays one continuous curve that corresponds to the actual program sequence. Furthermore, before or after the input operation,
The time scale and temperature scale can be preselected and stored by the input keys 2-5. Finally, the entire program can be stored, which controls the processing device according to this stored program. In the same way. Of course, the program stored in the storage of the sewing machine can be selected and can be displayed on the screen 1 and, if necessary, can be changed by the input keys, and The modified form can be stored and used to provide control. Also, for this application,
The processing steps can be displayed on the screen.

FIG. 6 shows another embodiment in which graphics are displayed on the screen 1. It is assumed that the graphic represents the relationship between the diameter of the tool, for example the blade of a drill or milling machine, and its operating speed. The diameter is displayed on the vertical axis and the rotation speed is displayed on the horizontal axis. Further, a fixed scale is provided at the end of the screen, or the scale is displayed on the screen. The straight line through points 30, 31, and 32 corresponds to the velocity / diameter course. Starting from a given blade diameter, the intersection can be determined by vertical movement of the cursor, eg point 30 or point 31 or point 32, and then by horizontal movement of the cursor the associated rotational speed can be determined. Can be read. However, the associated value can also be determined by the processor and displayed. The shape of the curve is
If the type of blade is different or the type of material to be processed is different, it can be varied to some extent, which is indicated by the special curve 33 of the screen 6. As mentioned above, such a curve, which does not necessarily have to be a straight line, can be traced and stored point by point.

A graphic of the type just described is shown in FIG. In this case, the function 34 is registered point by point according to the method. The function corresponds to a defined program, eg an inspection program. Again, the vertical axis displays time and the horizontal axis displays the given value or given function. In this case, the program course can be displayed by the cursor as in the case of FIG. The cursor can then follow the program curve 34 according to its time progression during program control. Alternatively, as the program progresses, the screen surface under the program curve can be illuminated and displayed.

As shown in FIG. 1, the construction of the present invention allows the input device to be particularly beautifully designed. The input keys 2 to 5 are arranged, for example, at the corners of a square circumscribing the screen 1. However, the input keys 2-5 can also be arranged in a circle surrounding the screen or in other geometric shapes.
