DE2823423A1 - Paper form processing and printing memory typewriter - utilises single printed line display in front of printing roller - Google Patents

Abstract

The form printing and processing arrangement is used in memory typewriters by using a single line display. The important information is made available to the operator at a convenient position to the operator and the display is arranged directly in front of the printing roller. Each individual position of the display in full line width is associated accurately with the printing position of the printer with the same representation of the character to be printed. All characters of a line are shown on input of a line together. Only one part of the line can be represented in the display in which the display is moved to the right of the complete filling on further input. Hence the superposed display contents and the printing output are made to agree.

Description

Procedure for processing forms

in a memory typewriter The invention relates to a method for processing forms in memory typewriters using a single line display in conjunction with a form-specific paper transport in the printer.

Typing error when labeling forms and preprinted forms with carbon copies are very difficult to remove. Usually the complete set of forms has to be thrown away will. Typos should therefore be eliminated before printing on paper will.

Should texts already stored in the Specher typewriter be in Forms are inserted, the content and format of the texts must be printed out checked and corrected if necessary.

The instructions in small print are usually difficult to fill out on forms read as soon as the form is clamped in the typewriter. It is one Help with making the relevant filling instructions visible is desirable0 It is known that memory typewriters and time machines are used for similar work can be used with a screen or line display (see also German Patent No. 2529783 and 2742992).

Devices with displays that are common today, however, leave the necessary context Missing with the paper to be printed, as none is easily seen and unambiguous Assignment of a display point to a print position on the paper is available.

In addition, the operator guidance is in the representation and description of the field to be filled in on the screen can only be reached with great difficulty.

The invention is based on the object of avoiding these disadvantages and the operator all information that is important to him in a convenient place This object is achieved according to the invention in that the single-line display is brought into congruence with the paper to be printed, which is achieved by that it is installed immediately in front of the writing whale, so that the display and paper form an optical unit. The form is clamped in the platen in such a way that that, in contrast to conventional typewriters, the line to be written on is aligned with a title block marker above the single-line display.

The form is only displayed before the printing process, without any action on the part of the user brought to the print line and then immediately back to a line break pushed forward so that a new line can be entered. The single line display is shifted so far up during the printing process that the print line for the Printing mechanism is accessible and immediately afterwards lowered again.

In order to be able to reduce costs for simple areas of application the display can be limited to a sub-area of the line to be printed, whereby this display then moves horizontally to the right in the course of the increasing filling level of the line is moved so that there is always a match between the display content and the printout in the same column prevails, with a carriage return, the entire - is already Invisible and visible line content output0 It is also desirable display up to 3 lines for demanding tasks, with the following lines either additional text, print control commands (such as superscripts of characters) or Information for the user - (e.g.

via machine states). The display field will extended downwards for this purpose.

Filling out forms is made much easier because of typing errors faster when entering texts and data, safer and less Leaving traces behind than can be eliminated up to now. Before printing on the paper you can make sure that the content of the text and the format of the printed image are OK and correct both in the single-line display if necessary, On Embodiment of the invention is shown in the drawings and is in explained in more detail below. 1 shows a schematic detailed view of the platen area a memory typewriter with a single-line display, FIG. 2 is a schematic diagram the intended system arrangement, FIG. 3, the paper movements when writing on forms.

lone. 1 shows the platen 1 of a printing unit in front of the one-line display 2 is built in. This display can contain the content of Represent information memory cells and has for system return messages, tax z calibration and user guidance further special characters in the character set. In the machine a set of forms 3 to be filled out is clamped in, with a field 4 with the text A 'has already been filled in and transferred to paper by entering a line break wardc, then the next field to be filled in was 5 with the small print Filling-in instruction 6 has become visible above the single-line display Now text can B 'entered for field 5 and corrected as required in the single-line display and This is made easier by having the exact position of the text both in the horizontal direction (- column division) on the single-line display as also read in the vertical direction on the transparent writing; field marking 7 can be.

Fig. 2 shows a schematic diagram of the proposed system arrangement the data flow. Texts, data, system control commands ( e.g. deleting texts) and Druc1; control commands (e.g. superscript characters ) entered.

The central processing unit 9 processes the inputs accordingly the system status and fills the output buffer 10, which contains the information for the display 2 contains. If you enter a carriage return, the content of the buffer 10 are transferred to the print buffer 11 and then printed out on the printer 12. As soon as the content from 10 to 11 has been transferred, new text can be entered.

Fig. 3 shows the paper movements during a form-labeling process, applied relative to the title block marker 7. In chronological order executed the following movements: Clamping the form and line for 'Text A' align with the marking field marker 13 * At 14 the system moves the paper to the Print line around it afterwards, increased by an adjustable line break 15, again to bring up 16. 'Ilext B' can be written.

Movement 17 corresponds to movement 14, movement 18 corresponds to movement 16 etc. In order to have a larger section of paper visible above the display if necessary can be made by entering a command in the central processing unit the movements 14, 16 etc. are increased by an amount. The title block marker must then be removed from the advertisement by the same amount. Used for this ad area If the value 0 is selected, a copy function takes effect, with the entire content the old line is taken over into the Anse », where it is entered before a new one Line feed can be changed at will. In this case the copying remains the old line is in the title block marker for better matching, the selected line break ensures that the new line is printed in the correct line. This facility makes writing tables much easier, as often large parts of the previous line are transferred unchanged to the new line can.
