DE2823423C3 - Typewriter with a single line display - Google Patents

Description

The invention relates to a typewriter with a single display according to the preamble of claim 1. With such a typewriter can Forms are aligned and correctly filled in with regard to content.

It is known that memory typewriters and text machines with a screen are used for such work or line display can be used. The text entered is made visible in these displays and it can be checked and corrected before printing (see, among others, German patents 29 783, 26 21 146 and 27 42 992). The screens are placed on the side or above the paper to be printed, Displays with a display capacity of one partial line up to a few lines in the Dnieker housing even arranged between the keyboard and the paper to be treated. Should already be visible in the display Texts are changed, the operator must use the control keys to identify the incorrect position in the Activate the display and then incorporate the desired change there. At the same time is in one Memory storage the change from the original

Text.

Devices with screens and displays that are common today, however, allow the necessary connection with this Missing printing paper, as there is no easily visible and unambiguous assignment for the operator Letters in the ad to a print position on the paper is also possible when filling out of forms today, the small print instructions to fill in are often very difficult to read because they are of the Printing devices are covered.

The invention is based on the object of a typewriter with a memory device in particular For form processing, specify a possibility for the exact alignment of the text to be written in Direction of the writing line and the recording medium advance.

This object is achieved by the invention characterized in claim 1. The single display is for the operator immediately in front of the printing paper, with each display position offset perpendicularly to a print cell on the paper assigned. This assignment can be made without the aid of mechanical aids - such as a line ruler - or electronic aids - such as writing position indicators - can be recognized at a glance.

The form is clamped in the typewriter in such a way that the < '' differs from conventional typewriters in the line to be written above the Line display is aligned with a title block marker. The The form is brought to the printing unit without any action on the part of the user and then immediately transferred again to a Line break advanced so that a new line can be entered.

This device enables the operator to do the, mostly small print. Instructions to fill in on forms to read easily before filling in the relevant field, even if the instructions are below of the field to be filled in

In order to be able to reduce the costs for simple areas of application, the can according to claim 2 Display can be limited to a sub-area of the line to be printed, this display then in the course the increasing degree of filling of the line horizontally to the right, so that there is always a correspondence between the display content and the printed output in the same column prevails. When entering a print command, the entire - already invisible and visible - line content output.

To repeat the text of the last printed line in the current writing line, a Copy function according to claim 3 can be called. The largest repeats itself, especially with tables Part of the line content in the following line. The operator leaves this constant text in the Single display unchanged. Only the deviating characters have to be used in the single display Way can be changed before the print command. Here, the alignment of the individual pressure gaps is direct Recognize and correct column changes are made easier because the old text is in the title block marker is exactly above the new text in the line display.

An embodiment of the invention is shown in the drawings and will be described in more detail below explained. It shows

F i g. 2 a schematic diagram of the proposed system arrangement and

Fig. 3 the paper movements when writing on forms.

F i g. 1 shows the platen 1 of a printing unit, in front of which the single-line display 2 is installed Form set 3 clamped in, whereby a field 4 with the "Text A" has already been filled in and transferred to paper by entering a print command. The next field 5 to be filled in was then visible with the filling instruction 6 in small print above the one-line display 2. "Text B" can now be entered for field 5 and corrected and shifted as required in single-line display 2. This is facilitated by the fact that the exact position of the text can be read both in the horizontal direction (= column division) on the single-line display 2 and in the vertical direction on the transparent text field marker 7.

F i g. 2 shows the data flow in a schematic diagram of the proposed system arrangement. Via a keypad 8 texts, data, system control commands (e.g. deleting texts) and print control commands (e.g.

Superscripts of characters). The central processing unit 9 processes the inputs accordingly the system status and fills the memory device 10, which stores the information for the single-line display 2 contains When a print command is entered, the content of the memory device 10 is stored in the print buffer U transferred and then printed out on printer 12 as soon as the contents of the storage device 10 has been transferred to the print buffer 11, new text can be entered

F i g. 3 shows the paper movements during a form-writing process, plotted relative to the title block marker 7. The following movements are carried out in chronological order: Clamp the form and align the line for "Text A" with the title block marker 7 (movement 13). The movement 14 conveys the paper to the printing position, in order to then bring it back up again, increased by an adjustable line feed 15 (movement 16). "Text B" can be written. Moved- ·>; 17 corresponds to movement 14, movement 18 corresponds to movement 16 etc. In order to be able to show a larger section of paper above the display if necessary, the movements 14, 16 etc. can be increased by an amount by entering a command into the central processing unit. The title block marker 7 is then to be removed from the display by the same amount.

Claims (3)

Patent claims: 1. Typewriter with a single display, in the at least part of a text to be written in a line can be entered, a memory device for the intermediate storage of the in the Single line display of entered text and a printing unit for printing out the text stored in the memory device on a recording medium after entering a print command, ι ο the text entered in the line display and memory pending its printing can be corrected and aligned within the line. characterized in that the single display (2) at eye level immediately in front of the Platen (1) is arranged that over the Single line display (2) a text field marker (7) is provided on which the line to be filled in is a Form set (3) is aligned before printing so that the dimensions of this line as well as a possibly existing filling instruction (6) are visible to the writer that the Form set (3) can be moved into the printing position with the input of the print command (movement 14), and that after printing the stored line the next line of the form set (3) in the text field marker (7) is transported. 2. Typewriter according to claim 1, characterized in that the single display (2) is does not extend over the full line width and only part of a line can be displayed in it, and that the Single display after full filling at further input can be shifted in the writing direction, so that the display content is superimposed and printout match. 3. Typewriter according to claim 1 or 2, characterized in that for repeating the Text of the last printed line with only minor changes by a copy function of the text of the last printed line in the Memory and the single line display (2) can be taken over, where it can be changed in the usual way.
