Abstract: A document editing hyphenating text words to obtain a more efficient use of the print material and provide a more aesthetically pleasing printed document. The apparatus has a keyboard for inputting text and including a hyphenation key. Also included in the apparatus are a display, a CPU, and a word dictionary that stores data of hyphenation positions of words. Once text is entered into a hot zone at the end of a line, the CPU executes line advance at the first space in the hot zone or the space preceding the word entered in the hot zone. When hyphenation is selected by the operator, based upon the displayed text, a cursor is moved to the left of a current line and the CPU calculates how many letters can be added to the right end of the preceding line. The CPU produces a display immediately above the word to the right of the cursor that indicates the number of letters that may be moved to the preceding line.

Abstract: A document processing apparatus which can hyphenate the input document information and can display and print the hyphenated document in the same form is provided.

Abstract: An electronic typewriter having a punctuation checking feature checks each punctuation feature as it is stored in a memory section, against a set of predetermined rules which define punctuation errors in terms of the context of the punctuation mark. If the punctuation mark does not agree with the defined rules, a suitable alarm, such as a visual and/or audible signal is given to the typist. A plurality of algorithms form the basis for sub-routines which a microprocessor can execute to determine if any of the rules are violated. The punctuation of a complete file can be checked by calling out each character in the file, from beginning to end and applying the checking procedure.

Abstract: The disclosure relates to a printing device which includes so-called hot zones wherein a punctuation or hyphenation is automatically performed in accordance with a predetermined rule thereby letting users be free from the inconvenience of line end arrangements and also enabling users to pay attention to the text printed on the sheet when attention is needed for a particular format, since the printing is ordinarily conducted at least before the hot zone.

Abstract: A document processor having a keyboard, a displaying apparatus for displaying inputted characters and symbols on a display and a control device for controlling the displaying apparatus, there is provided an improvement that permits the moving of an inputted word separated at the right margin set position on the display to the start of the succeeding display line by wordlap control, such that the separated word is displayed distinguishably on the display, for example, by blinking, in order to distinguish the separated word to an operator before moving the word to the succeeding line.

Abstract: An electronic typewriter has a right margin zone hyphenation system operable with an error correction function to provide a reasonably aligned right margin of printed lines on a work sheet. To hyphen a word or a partial word printed in the hyphenation zone, the operator positions a print mechanism to a hyphen position within the word and depresses a hyphen key. The electronics automatically erases the characters at the hyphen position and to the right of the hyphen position, prints a hyphen at the hyphen position, moves the print mechanism to a left margin, indexes the work sheet and prints the characters erased from the preceding line at the left margin on the next line. The hyphenation system is also operable to automatically erase an entire word in the hyphenation zone and reprint the word on the next line.

Abstract: When a number of input key data sequentially stored in a first line buffer memory from a keyboard coincide with the contents of a right margin memory in a RAM, the line data up to the word immediately preceding the word reaching a preset right margin is sequentially transferred from the first line buffer memory to a second line buffer memory. The number of input key data from the immediately preceding word to the preset right margin is counted. In accordance with the count thus obtained, a spacing adjustment of the spaces left between words of the line data transferred to the second line buffer memory, is performed under the control of a CPU prior to printing of the words according to the contents of the second line buffer memory.

Abstract: Method and apparatus for performing true right justification applicable to character printers utilizing variable character spacing. The method of the present invention may be applied to any printer that is capable of variable character pitch settings in response to external control signals. In addition to such a printer, apparatus includes a word processing terminal, and a microcomputer dedicated to the terminal and printer and designed to map the features of the terminal into features available in the printer. In addition to the functions of initialization, data discrimination, control code examination, and vertical carriage positioning, two other functions are provided, one of which does mapping and horizontal carriage positioning, the other of which comprises a service routine used by the other functions to read, write, or store characters and to calculate dimensional values.

Abstract: In a typewriter having text storage capability, the hyphen code that is stored in response to depression of a hyphen key is conditioned on printing position and on the codes adjacent to the hyphen code in a text string. If a hyphen is keyed after the start of the return zone, is preceded by a graphic representative code and is followed by a keyed carrier return, a distinctive hyphen code representative of a syllable hyphen is recorded. Otherwise, a regular hyphen is recorded unless the hyphen key has been depressed in conjunction with a condition key (e.g. the CODE key), in which case a code representative of a required non-breaking hyphen is recorded. As a result of so controlling the recorded hyphen codes at the time of keyboarding, the operator's intentions for hyphenation may be achieved with little departure from normal keyboarding routine.

Abstract: In a word processing system there is provided: apparatus for automatically centering a string of characters delivered by a source onto a line of a record medium such as a cathode-ray tube display; and apparatus for changing weak or optional hyphens to strong or mandatory hyphens when the hyphen is preceeded or followed by a numeric character.
