Abstract

A method of displaying types of script whose characters are arranged next to one another in rows or underneath one another in columns, by means of a raster-type display device or a vectorially controlled display device which receives its control signals from a character generator which can be controlled so that its output signals to the display device cause the displayed characters to be either upright or rotated by 90° (lying down) horizontally next to one another. With the latter mode of operation, a record carrier taken from a recording device and rotated by 90° (or a video screen rotated by 90°) then shows the printed text in the desired shape in which the characters are arranged underneath one another in columns.

Claims

1. In a method for displaying scripts whose characters can be arranged either one next to the other in row lines or one underneath the other in column lines using a display device which displays characters line by line and a character generator which derives, from the data of a stored character supply, actuation signals for the display elements of the display device, said method including the steps of deriving, by means of the character generator and in response to an input signal corresponding to a desired character, actuation signals for the display device representative of the desired character, and displaying the desired characters at desired positions in a display line on a display medium in response to said actuation signals;

the improvement comprising;

providing a first selectable mode of operation of said character generator wherein said actuation signals will cause the desired individual characters of a display line to be displayed upright and next to one another, and a second selectable mode of operation of said character generator wherein said actuation signals will cause the desired individual characters of a display line to be displayed next to one another but rotated by 90°

with respect to the characters in said first mode; and

, prior to said step of displaying, selecting one of said first and second modes of operation, whereby the desired characters are displayed next to one another in the same display positions of a display line regardless of the selected mode of operation.

2. The method as defined in claim 1 wherein:

the display device is a raster-type display device containing said elements arranged in vertical or horizontal rows; and

wherein said step of deriving includes obtaining said actuation signals for a character to be displayed from the stored data of the rows of a desired character for one of said first and second modes of operation, and from the stored data of the columns of a desired character in the other of said first and second modes of operation.

3. The method defined in claim 1 wherein the display device is a raster-type display having a plurality of recording elements which are actuated in vertical and horizontal coordinates;

wherein the actuation signals for the display device normally derived from the stored data corresponds to one of said modes of operation; and

wherein the other of said modes of operation is provided by transforming the stored data of a character to be displayed with respect to its actuation information for horizontal coordinates, to that for corresponding vertical coordinates and with respect to its actuation information for vertical coordinates into that for corresponding horizontal coordinates by means of a transformation function in the character generator.

4. The method defined in claim 1 wherein the display device is a vectorially controlled display device;

and wherein said first and second modes of operation are provided by;

deriving horizontal and vertical deflection signals for the recording element of the display device from the stored data of a desired character to be displayed in one of said first and second modes of operation; and

in the other of said first and second modes of operation, transforming said derived horizontal and vertical deflection signals into respective vertical and horizontal deflection signals of the same respective magnitude by means of a transformation function in the character generator.

5. A method as defined in claim 1 wherein the display device displays characters row by row and is normally operated with said first mode of operation with the individual said characters being displayed upright and horizontally next to one another in each row;

and wherein, in said second mode of operation, the corresponding individual said characters are displayed horizontally next to one another and in the same position along a row as in said first mode of operation, whereby a machine normally used to provide a display of characters arranged in row lines may be used to provide a display of the same characters arranged, when upright, in column lines.

6. A method as defined in claim 5 wherein the display device is a printer and the display medium is a sheet of paper.

7. A method as defined in claim 1 wherein each of the characters is rotated in the same direction in said second mode of operation.

8. A method as defined in claim 7 wherein each of said characters is rotated in a counter clockwise direction in said second mode of operation.

9. In a method for displaying scripts whose characters can be arranged next to the other in rows or next to one another in columns on a display medium using a display device which displays characters line by line in only one orthogonal direction and a character generator which derives, from the data of a stored character supply, actuation signals for the display device, said method normally including, in response to input signals corresponding to desired characters, and by means of the character generator, deriving first actuation signals for the display device which are representative of the desired characters and which will cause the individual characters of a display line to be displayed upright, feeding said actuation signals to the display device, and displaying the individual desired characters next to one another at desired positions in a display line in response to said first actuation signals;

the improvement comprising;

in response to a selectable input control signal,

transforming said first actuation signals to modified actuation signals which will cause the individual characters of a display line to be displayed rotated by 90°

in the same direction with respect to the characters displayed in response to said first actuation signals,

feeding said modified actuation signals to the display device instead of said first actuation signals, and

displaying the individually rotated characters next to one another at said desired positions in said display line in response to said modified actuation signals, whereby the individual characters of a display line produced following receipt of said control signal will be upright and arranged in the other orthogonal direction upon physical rotation by 90°

of the display medium bearing the displayed line of characters.

10. A method as defined in claim 9 wherein said direction of rotation is counter clockwise.

11. A method as defined in claim 9 wherein the display device is a memory typewriter which prints row by row, and said step of displaying include printing the individual characters horizontally next to one another in each row.

12. A method as defined in claim 11 wherein said step of displaying includes sequentially displaying the individual characters of a row from left to right, and said direction of rotation is counter clockwise.
