Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
In a data processing device comprising input means for inputting character data and format data, display means for displaying the input data and means for processing the input data and displaying the processed input character data on said display means, the improvement comprising: said display means includes a screen which is separated into (1) a line format area containing a horizontal scale which indicates the input range of one line with character columns corresponding to standard printing spacing and (2) a data display area for displaying processed character input data, and said processing device is further provided with shift means for shifting the data displayed on said line format area relative to the data displayed on said data display area.
Claim 2
Dependent Claim
120 words
In a data processing device comprising input means for inputting character data and format data, display means for displaying the input data and means for processing the input data and displaying the processed input character data on said display means, the improvement comprising: said display means includes a screen which is separated into (1) a line format area containing a horizontal scale which indicates the input range of one line with character columns corresponding to standard printing spacing and (2) a data display area for displaying processed character input data, and said processing device is further provided with shift means for shifting the data displayed on said line format area relative to the data displayed on said data display area.
Claim 3
Dependent Claim
190 words
The data processing device according to claim 1 which further comprises a data memory for storing various data which are entered from said input means, said data displayed in said line format area designates a scale which indicates the input range of one line with its colums corresponding to standard printing spacing, printing means for printing the data onto the printing medium at varying printing space in dependence on the corresponding character width, a printing spacing memory for storing the printing spacing of each character, printing space summing means for calculating the sum of corresponding printing spaces of the characters to be entered from the beginning to a predetermined position of said input range on said display means, column number calculating means for calculating the number of columns by dividing said sum of printing spaces by said standard printing space, and said shifting means comprising means for shifting said scale so that the column which is positioned closer to the end of the line by said number of columns from the column corresponding to the beginning of said input range is placed in a position corresponding to said predetermined position.
Claim 4
Dependent Claim
124 words
The data processing device according to claim 2 which further comprises means for calculating the total width of the characters positioned to the left of a text cursor position on a line where the text cursor exists; means for calculating the column where the text cursor exists; means for calculating the column where the scale cursor exists; means for comparing said columns of the text cursor column and the scale cursor column; means for shifting the scale cursor toward right on the display screen when the column of the text cursor is larger than the column of the scale cursor; and means for shifting the scale cursor toward left when the column of the cursor is smaller than the column of the scale cursor.
Claim 5
Dependent Claim
140 words
In a data processing device comprising input means for inputting character data and format data, display means for displaying the input data and means for processing the input data and displaying the processed character input data on said display means, the improvement comprising: said display means includes a screen which is separated into (1) a line format area containing a horizontal scale which indicates the input range of one line with character columns corresponding to standard printing spacing and (2) a data display area for displaying processed character input data, and said processing device is further provided with shift means for shifting the data displayed on said line format area relative to the data displayed on said data display area to stand still while making the screen in said line format area moveable when a format setting mode is entered.
Claim 6
Dependent Claim
140 words
In a data processing device comprising input means for inputting character data and format data, display means for displaying the input data and means for processing the input data and displaying the processed character input data on said display means, the improvement comprising: said display means includes a screen which is separated into (1) a line format area containing a horizontal scale which indicates the input range of one line with character columns corresponding to standard printing spacing and (2) a data display area for displaying processed character input data, and said processing device is further provided with shift means for shifting the data displayed on said line format area relative to the data displayed on said data display area to stand still while making the screen in said line format area moveable when a format setting mode is entered.
Claim 7
Dependent Claim
60 words
The data processing device according to claim 4, wherein a scale for indicating the position of margins and tabs and a cursor movable along said scale are displayed on the screen of said line format area and, when said cursor moves outside the screen of said line format area, the whole scale is horizontally moved together with the cursor movement.
Claim 8
Dependent Claim
39 words
The data processing device according to claim 5 further comprising means for reforming the character data based upon the newly set format, and means for shifting the scale line to meet with the text data displayed on the screen.
