Word processor

The invention relates to a text processing prep * . ^ direction with an input keyboard, a control and storage unit, a viewing device and a print output unit. .

■■ ''. ·

In such word processing devices -will the characters (letters or characters) written by the operator using the input keyboard continuously recognizable via the vision unit. Errors can be corrected by adding individual characters be successively replaced by others. Only when the text that can be displayed on the viewing unit is free of errors, it is printed out. It is true that these word processing devices, especially when used as a viewing unit A screen is used that is largely recognizable in what form the text appears, but it will be different Depending on the font selected when printing, there are still differences when the font does not match the standard font of the viewing unit. Thus, under certain circumstances, it becomes a multiple Expression required to determine which font is best for a document.

The invention is based on the object for the operator of a word processing system to make it easy to identify the visual effect of the characters before printing bring me a certain font.

This object is achieved by the features in the characterizing part of claim 1.

With such a word processing system for the operator immediately when entering characters via the input keyboard recognizable like the written text; looks optically in the selected font. The division of the text can therefore be adapted to the font. The visual effect of a text can be achieved even before it is printed out be assessed. This is particularly advantageous when using so-called proportional fonts, Even if phototypesetting machines are used as print output units, they are preparatory Steps for the setting process kept to a minimum.

In a further embodiment of the invention, the setting device has a detection device, which determines the type used in the print output unit and in the control and storage unit a selection device controls' which the characters belonging to the recognized type type for display on the screen. This has the advantage that · that it appears automatically in a specific font the display unit lets write · as soon as a certain Font has been selected.

The word processing device according to the invention is particularly simple, if a type wheel printer is used as the print output unit. Different fonts can be achieved by exchanging the type wheel.

A code that is decoded by the recognition device can be attached to the character wheel. so that corresponding signals are output to the control and storage unit for calling up the corresponding font will. The word processing device according to the invention is, advantageously further developed, that the print output unit receives a character of the character

-5-. 3323S77

Set of special font can be recognized by the decoding device and the decoded values the control and storage unit passes on. In such an embodiment, for the print output unit as far as possible conventional ingredients are used.

An embodiment of the invention is described below by way of example with reference to the drawings. The figure shows a block diagram with the input keyboard, the control and storage unit, the viewing device and the print output unit.

The illustrated 'embodiment shows a type wheel printer 1 as a print output unit A character wheel printer is used to select the font by exchanging the ones used as printing elements Type wheels. Such type wheels are available for almost all fonts and a large number of special character sets.

The type wheel 2 used is recognized in this embodiment by a button attached to the print head Detection device 4, which detects the identifiers 3 attached to the type wheels and to the control and Memory unit 5 reports. . '

The following detection or identification methods can be used, for example: Barcode, identification with the help of magnetic stripes and identification with the help of mechanical scanning.

The output of the detection device 4, which is mounted opposite the character wheel, is with a coincidence circuit β of the control and storage unit 5 connected. At jiie coincidence circuit 6 includes Selection decoder 7 on. The control and storage unit has an input keyboard 8 and a screen tied together. There is also the control and storage unit

-6-. 3323S77

connected to the character wheel printer 1 to control it. ·. V-; · -..-. -.

The characteristic values of the respective type wheel 2 recorded by the recognition device 4 are converted after level conversion and automatic error detection with correction as electrical impulses in serial or parallel Form transmitted to the control and storage unit 5. The characteristic values are recorded either automatically by the control and. Storage unit 5 initiated or at Required triggered by the operator. The type wheel 2 for this purpose one complete revolution in the forward direction off and after completion of this revolution, a full revolution in the reverse direction tion. As a result, the identifier 3 on your type wheel 2 both in the forward rotation and in the. Reverse rotation read in their basic position. If both values are recognized as identical in the coincidence circuit 6, further processing takes place in the control and storage unit 5. Otherwise, the Control and storage unit again from an identification process. In addition to automatic detection of the type wheel used, it is imperative for texts with different fonts that the Operator can manually trigger the recognition process at any time.

The word processing device remembers texts that were created with different type wheels 3 the point at which the type wheels 3 are changed and gives a note on the printout the use of the correct type wheel through a pause in printing and the request to the operator, to use the type wheel "XY". Alternatively, the text is first printed out in full in normal font, then the printer moves the paper back to the beginning or to the first position where the special characters

or other types must be used, so that after replacing the type wheel, the characters in the new Print fonts one by one in the spaces.

It is entirely possible to query the identifier by turning the type wheel once, whereby -but the advantage of the additional error correction get lost.

The data taken from the type wheel 2 are transferred to the Input into the control and storage unit 5 via the Coincidence circuit 6 in a selection decoder 7 with a rather unit 5 stored in the control and storage unit Table compared, and if there is a coincidence, the determined character set is adopted as the editor character set. Will no match found with a table, it takes place another query of the type wheel 1, and if the characteristic data is again missing in a table An error message is given to the operator by the control and storage unit, and the standard character set becomes the standard provided for the viewing device or the operator the choice of all available Fonts left for the viewing device.

The character sets of different fonts provided for printing are stored in a read-only memory of the control and storage unit 5 (any computer from any manufacturer) and are manually selected from a large number either by the user before or during the entries. The fonts in question can, however, also be selected automatically by the control and storage unit after recognition in the connected print output unit by feedback of the font used from the Fe stwertspeicher and transferred to the word processing device for further processing.
