Abstract

An operator panel for printers which includes visible function indicators as well as trigger elements for controlling printer functions has a single function operating and indicating field arranged in a matrix fashion with lines and columns wherein the lines indicate classes of functions and wherein a particular column includes designations as well as indications for the classes of functions; there is at the most one indication and/or one designation in any matrix intersection, a single key is associated with each of the columns; a second panel field is disposed alongside the first one, having a single operating key, and being individually organized commensurate with the lines and in a single column but being independent from said designations of the particular column.

Claims

1. Operator panel for printers which includes visible function indicators as well as trigger elements for controlling printer functions comprising:

an operating and indicating field arranged in a matrix fashion with lines and columns wherein the lines indicate classes of printer functions, and wherein a particular column includes designations as well as indications for the classes of the printer functions;

an intersection of a line of a column including at the most one indication and/or one designation;

a single key separated from and associated with each of the columns whereby keys associated with the particular column select only designations and indications associated with that column and keys associated with columns other than the particular column select the respective column with which such a key is associated; and

said key in said particular column operating a step switch to run through the line class indications one by one and on a cyclic basis to thereby select the respective line.

2. Operator panel as in claim 1, and including a second panel field disposed alongside the first one, having a single operating key, and being individually organized commensurate with said lines, and in a single column, but being independent from said designations of the particular column.

3. Panel as in claim 2, said single operating key also being or operating a step switch to run through the line class indications one by one and on a cyclic basis.
