Definitions

  • the invention relates to a method for displaying characters on a one-line display device of a text station in accordance with the preamble of claim 1.
  • the characters entered are first displayed on a display device before being printed out, in order to give the user the opportunity to check the correctness of the characters entered and, if necessary, to carry out a correction by means of a new entry. Only then are the entered characters printed on a print substrate, e.g. a sheet of paper, printed out.
  • a print substrate e.g. a sheet of paper
  • a one-line display device e.g. of a one-line liquid crystal display
  • a verbal text in which the individual characters of a line are formed as letters and are arranged on a single base line running in the horizontal direction.
  • Such character combinations are, for example, mathematical expressions which have an exponent (superscript), an index (subscript) or a quotient consisting of numerator and denominator (superscript and subscript).
  • the invention is based on the object, while avoiding the previous disadvantages, of specifying a further method which enables the display of character combinations with superscript or subscript on a single-line display device in a simple manner, with a clear assignment between individual character positions on the display device and the printing proof is guaranteed.
  • the arrangement shown in Fig. 1 is formed from a text station.
  • This text station has a central control ZS.
  • the text station consists of a keyboard TST for entering characters as well as a printer DR and a display device ANZ.
  • a character generator ZG with a downstream pixel memory BPS.
  • the characters entered via the TST keyboard are stored in the pixel memory BPS in the form of a character pattern.
  • This character pattern is read out cyclically from the pixel memory BPS and brought to the display device ANZ.
  • the characters displayed on the display device ANZ are printed out at a later time by means of the printer DR on a printed document which is clamped in the printer DR.
  • the printed characters of each line or partial line are here on a base line corresponding to a basic position and / or on different high and low positions.
  • the following character string is given as an example:
  • the character string B + C is in the superscript, the character string D + E in the subscript. All other characters are on the baseline corresponding to the basic position.
