Definitions

  • the invention relates to an arrangement for displaying characters on an office, remote or data storage typewriter, in which at least some of the characters of a text entered by means of a keyboard are temporarily stored, displayed and then printed.
  • T extautomaten the characters entered are simultaneously saved in a buffer.
  • the typing error is overwritten on the original and a new original is created in a second printing process.
  • This type of correction increases paper consumption by at least twice and the preparation times are greater than in a conventional B üroschreibmaschine in single letter generation.
  • Automatic text machines are also known which are provided with a screen on which at least a large part of a page of a letter can be displayed. A text can be printed out initially displayed on the screen and corrected if necessary and subse- be printed ß end. Such screens have proven themselves in automatic text machines, but their use is not always expedient in simple office typewriters.
  • characters on the keyboard of the office typewriter they are first displayed on the display unit and printed after pressing a "release button".
  • the display unit is connected to an intermediate memory in which the displayed characters are stored. After recognizing a typographical error before the characters are printed, the incorrect character is changed in the buffer.
  • the known display unit can have a variable installation location and can be arranged, for example, in the immediate vicinity of a template.
  • This known display unit also requires a relatively large outlay since a large number of display elements are required to display a plurality of words are. If the display unit has a variable installation location, it needs its own housing and a corresponding connection cable to the office typewriter. In addition, an operator may find it disadvantageous that they not only have to change their viewing direction between the original and the impression point, but also have to observe the display unit in a further viewing direction.
  • the invention is therefore based on the object of specifying an arrangement for representing characters on an office, long-distance or data typewriter which requires little effort and which enables correction of input errors which are recognized immediately after input in a simple manner.
  • characters are understood to mean letters, numbers and special characters, such as punctuation marks, diacritical marks, signs for words, unit signs, number symbols, arithmetic signs and spaces.
  • the object is achieved in the arrangement of the type mentioned in that a plurality of characters display unit is arranged in the printing direction immediately before the printing point of the characters, on which the most recently entered characters are displayed in such a way that they are from the characters already printed continue the text immediately.
  • the arrangement assumes that the majority of input errors occur as a result of thought disorders, lack of concentration or environmental influences, and that the twists in the order of characters and false triggering are recognized immediately after input. This is only one display unit for a few, for example wise four characters, required.
  • the incorrectly entered characters can be corrected immediately without additional resources, such as correction tapes, erasers, correction strips, etc.
  • the result is a clean and error-free original, despite corrections. No correction is required on the carbon copies either.
  • contamination of the typewriter as a result of eraser particles or the like is avoided and simple noise reduction of the typewriter is made possible since the impression point must be visible to the operator but not accessible.
  • the arrangement of the display unit immediately adjacent to the A bffystelle enables easy read along the text e s, as the text of the already printed characters and the immediately adjoining the displayed characters is displayed '.
  • this character is displayed at the first position in the display unit in the writing direction, when the previously displayed characters are shifted one position against the writing direction and at the last position characters displayed on the display unit are printed.
  • the characters displayed on the display unit can be addressed and changed. It proves to be expedient if the addressing of a displayed character is carried out by means of a backspace key provided on the keyboard The addressed character can be deleted automatically or shown flashing.
  • the characters A to K are on a letter roller as a character printed record carrier printed.
  • the printing takes place, for example, using a type plate 1 and an ink ribbon 2.
  • a printing window 5 is provided at the printing point on a line ruler 4 provided with a scale 3.
  • a display unit 6 is arranged in front of the printing point, on which several, for example four, characters can be represented.
  • the display unit 6 is arranged such that its upper edge coincides with the baseline of the writing line.
  • the characters L to O displayed on the display unit 6 have the same size as the printed characters and also have the same character spacing, which can be switched, for example, between 1/10 and 1/12 inch.
  • Each character entered is displayed at the position of the display unit 6 which is furthest in front of the printing point and is stored in a buffer connected to the display unit 6.
  • Each time additional characters are entered the characters already displayed and saved are shifted one place to the left. If characters are displayed at all points of the display unit and an additional character is entered, the character previously displayed at the position of the display unit 6 closest to the printing point is printed out at the printing point.
  • the characters displayed on the display unit 6 and stored in the corresponding buffer can be deleted or overwritten in a known manner. In this way, it is possible to correct input errors immediately that are recognized immediately after the input.
  • the arrangement of the display unit 6 directly at the impression point enables continuous reading of the partially written and partially displayed text without changing the viewing direction of the operator.
  • the division of the text on the record carrier for example at the end of a line or when filling out a form, is facilitated in that the characters are displayed in the display unit 6 in the same size and in the same character spacing as in the written text. In this case, it is easy to decide whether to separate or not at the end of the line.
  • the display unit 6 is arranged in front of the impression point in the viewing direction shown by an arrow.
  • the characters are printed above the display unit 6 using the type plate 1 and the ink ribbon 2 on the print window 5 in the line ruler 4 on the recording medium 8 placed around a platen roller 7. This gives full insight into the entire writing line and to the impression point, in order to enable form-compliant writing.
  • the chronological sequence in the representation of the text of a writing line 9 is shown.
  • the last, right position of the display unit 6 is arranged to the right of the beginning of the line 10, while the preceding positions are arranged to the left of this.
  • the first character for example the letter A
  • the record carrier 8 cannot be moved in the horizontal direction, but the printing unit is displaceable along der'Schreibwalze 7 is arranged a r b, the display unit is 6.an administratd together with the printer carriage on which the printing unit is fixed to a character pitch, for example, 1/10 inch or 1/12 inch to the right emotional.
  • the display unit 6 is also arranged in a fixed position at the impression point.
  • a corresponding key for example the backspace key
  • the addressed character can, for example, be automatically deleted immediately, or it can be highlighted by flashing or another identification. The correct character is then entered and the entry is continued.
