Abstract: A frame processing system is capable of expanding and contracting a frame having a plurality of frame lines to define a plurality of areas. One of the areas can be expanded or contracted without expanding or contracting the other areas. One of the frame lines is designated by a cursor, for example, and the designated frame line is moved together with the cursor on the display. At this time, all the other frame lines connected to the designated frame line are automatically expanded or contracted to maintain the connection therebetween.

Abstract: A program processing system including a program input device for entering optional programs for performing an optional function, an optional-program memory for storing the optional programs, a standard-program memory which stores a standard program for performing a basic function; a commanding device for designating one of the optional programs, for execution of the designated optional program, and a controller for retrieving the designated optional program from the optional-program memory, to perform the corresponding optional function, if the designated optional program is stored in the optional-program memory, the control means retrieving the standard program from the standard-program memory, to perform the basic function, if the designated optional program is not stored in the optional-program memory means.

Abstract: A data processor for speedier processing of input data includes a data processing system for executing a text editing process and a text printing process by the time slice method and a preference control unit for selecting between the above processes. When data is entered into the processor, the entering process or text editing process is generally preferred to the text printing process. Therefore, no delay occurs in inputting data through a keyboard from data entry to its display. If desired, it is possible to prefer the text printing process to the text editing process.

Abstract: In a text editing device, provided is an improved so-called wordout function, a word lying across two lines can be erased at one time with a single key operation. In case that a hyphen is located at the end of the line, it is determined that two divided parts of a single word are located on two lines.By detecting a hyphen between two character strings, these two strings are erased at one time as two parts included in a single word.

Abstract: A word processor having an output function for adding margin text, such as a heading or a footing to a main text, includes main text editor, margin text editor, print controller, display device and display device controller. The display controller displays the main text and the margin text simultaneously on the display device in the same form as they are printed out on a paper. Thus, the margin text can be set without printing while an operator confirms its print form.

Abstract: In a printing device, it is possible to automatically place a print head on the peripheral positions of the print area without actual printing operation.By employing the above arrangement, an operator can exactly determine a proper size of print sheet for the text to be printed, with no waste of sheet and printing time.

Abstract: In a text processing device, provided is an improved tabulation function. The vertical positions of horizontal ruled lines dividing two rows are calculated based upon the intervals existing between these columns. If the row interval is expanded or changed, the horizontal ruled lines remain consistent in a predetermined relationship with a character string.

Abstract: A word processor with a merge print function which permits an insertion data file to be easily formed without troublesome operations an insertion data field can be adaptively expanded or has the capability to adaptively expand or contract an insertion data field to cope with either longer or shorter lengths of input data. The expansion or contraction is executed either manually by a specific key operation, or automatically according to the data length.

Abstract: A word processor having attribute functions such as underline, boldface, superscript, etc., can produce or cancel those attribute effects on the display device by simple operations. The word processor with an attribute mode can either produce the attribute effect which is selected by an attribute key in response to the rightward or downward movement of the cursor, or cancel it in response to the leftward or upward movement. The word processor with an attribute cancel mode in addition to an attribute mode can set a mode among a non-attribute mode, an attribute mode and an attribute cancel mode independent of the direction of the cursor's movement.

Abstract: In a document processing apparatus, the top position of the input data visually displayed on a display unit is displaced toward the end of the line and the corresponding control code mark is represented before the top position of the input data when a control code therefor is input. The apparatus is provided with a shift inhibit for adding space codes in the corresponding area of the input data buffer so that format is not changed despite rewrite of the control code, and a shift permit for displacement of the top position after erasure of said control code mark by the erase signal. Thereby, deformatting is prevented and the document processing is easily carried out.
