Abstract

A display and/or operating device for controlling machines includes a projection device for projecting an image onto a projection area, an acquisition device for scanning the same projection area, and a control computer for controlling the projection device and the acquisition device. The present invention is distinguished by the fact that, by the acquisition device and the control computer, an analysis of the same projection surface can be carried out, and that the content of the image to be projected can be controlled by the control computer as a function of the result of the analysis of the same projection area.

Claims

1. A display and/or operating device for controlling machines, comprising:

a projection device for projecting an image onto a projection area;

an acquisition device for scanning said projection area;

a control computer connected to said projection device and to said acquisition device for controlling said projection device and said acquisition device; and

said control computer being programmed;

to carry out an analysis of said projection area with said acquisition device; and

to control content of said image to be projected as a function of a result of said analysis of said projection area.

2. The device according to claim 1, wherein said image is an operating interface.

3. The device according to claim 2, where said operating interface is to be projected onto a printing material of a press.

4. The device according to claim 2, wherein:

said operating interface is to be projected onto a printed printing material; and

said operating interface has an appearance that is changed by said control computer as a function of a nature of the printing material.

5. The device according to claim 1, wherein said projection surface has sides and said projection device and said acquisition device are on the same one of said sides with respect to said projection surface.

6. The device according to claim 1, wherein said projection device is disposed on one side of said projection area and said acquisition device is disposed on another side of said projection area.

7. The device according to claim 3, further comprising:

a sheet support;

a sheet-supporting desk having an interior; and

said projection device being disposed underneath said sheet support in said interior of said sheet-supporting desk.

8. The device according to claim 2, wherein:

said operating interface has operating elements; and

an appearance of said operating interface depends upon at least one of said operating elements one of touched and actuated on said operating interface.

9. The device according to claim 2, wherein changes made on said operating interface are displayed on said projection area by said projection device.

10. The device according to claim 2, wherein said operating interface is to be operatively connected to a press for controlling the press.

11. The device according to claim 2, further comprising a press, said operating interface being operatively connected to said press for controlling said press.

12. The device according to claim 11, wherein:

said press has operating elements for setting a register; and

at least one of said projection device, said acquisition device, and said control computer is configured to actuate said operating elements by touching a register mark on a printed sheet disposed in said projection area.

13. The device according to claim 11, wherein said press has an inking zone setting activated when a color measuring strip of a printed sheet disposed at said projection surface is touched.

14. The device according to claim 3, wherein:

a printed sheet serves as said projection area; and

measured values are projected onto said printed sheet at a point at which said values are actually measured.

15. The device according to claim 1, wherein said projection device, said acquisition device, and said control computer, together, are portable.

16. The device according to claim 1, wherein:

said projection surface has functionalities; and

said acquisition device acquires said functionalities; and

said control computer incorporates said functionalities in an output of said image of said projection device.

17. The device according to claim 7, wherein a size of a printed sheet lying on said desk is registered by said control computer through said acquisition device and a size of said image projected is adapted automatically to said registered size of the printed sheet.

18. The device according to claim 7, further comprising a color-testing lamp for illuminating a printed sheet lying on said desk, said color-testing lamp being connected to said control computer.

19. The device according to claim 18, wherein said projection device and said color-testing lamp are combined in one projection lamp.

20. The device according to claim 1, wherein said connection of said control computer to said projection device and to said acquisition device is at least one of wired and wireless.

21. A press, comprising:

at least one printing unit; and

a display and/or operating device for controlling said at least one printing unit having;

a projection device for projecting an image onto a projection area;

an acquisition device for scanning said projection area;

a control computer connected to said projection device and to said acquisition device for controlling said projection device and said acquisition device; and

said control computer being programmed;

to carry out an analysis of said projection area with said acquisition device; and

to control content of said image to be projected as a function of a result of said analysis of said projection area.
