Primary Examiner-Clifford D. Crowder Assistant Examiner-R. T. Rader Attorney, Agent, or Firm-Dorsey, Marquart, Windhorst, West and Halladay  ABSTRACT A right hand margin adjust feature for an automated Oct. 28, 1975 typing system 'for use with cassette tapes and other typing or display systems. This feature enables an automatic typing system of the class described to automatically reformat pre-recorded information according to changed margin settings of a typewriter or printing device or to compensate for words inserted or deleted in previously recorded copy. [t is responsive to, and functions to edit, sentence ending punctuation, spaces, tab, hyphens, carrier returns and line returns. Carrier returns and spaces will be added or deleted automatically as dictated by their position in the original copy and by the margin settings. Carrier returns in the original material are deleted and replaced by an appropriate number of spaces until a variable character right hand margin adjust zone is reached. The feature functions at the beginning of the right hand margin zone to analyze and evaluate the remaining char acters in the line. The last available interword space in the zone is deleted and replaced with a carrier return if possible. If a word extends through and beyond the variable right hand margin adjust zone, the system will stop, permitting the typist to read by character to the proper position for a hyphen. After the hyphen is typed and the carrier returned the system will continue to read and type in the automatic right hand margin adjust mode. The system will also stop for any previously recorded tab, permitting the typist to insert the tab if it is required or continue to read. Carrier returns at the end of a title, salutations, or a short line, and tabs and hyphens that will always be required may be kept by depressing a keep" key at the same time as the appropriate character key and thereafter will not be edited by the right hand margin adjust feature.

Such a console is described in part in our co-pending US. Pat. application Ser. No. 427,925 filed Dec. 26, 1973 entitled Search Feature for an Automated Typing System". A typewriter with an electronic keyboard, suitable for use with our invention is described in co-pending U.S. Pat. applications Ser. Nos. 336,240 and 439,310 filed Feb. 27, 1973 and Feb. 4, I974, entitled Typewriter with Magnetic Memory and A Keyboard for an Automated Typing System, respectively.
It should be understood however that our invention may be modified or adapted for use with many typing systems or justification systems for both automated typing and visual display.
An automated typing system of the class described performs the following operational functions. Information can be printed on hard copy and recorded simulta neously on magnetic tape. Information recorded on magnetic tape can be read and printed out as hard copy. Information recorded on magnetic tape can be duplicated onto a second tape in either a print or a nonprint mode. Tape reading, skipping, or duplicating can be stopped automatically on a word, line, paragraph or page and unwanted information recorded on magnetic tape can be skipped over when the tape is being read or duplicated. In addition, information recorded on a magnetic tape may be searched for selected printing or duplicating.
The feature which is the subject of this invention adds an additional function to those described above. By adding and deleting spaces and carrier returns automatically, as dictated by the right hand margin, it enables the automated typing system to reformat prerecorded information according to changed margin settings of the typewriter or to compensate for words inserted or deleted in previously recorded copy.
In the past the right hand margin of printed copy has been adjusted in primarily two ways. Some systems read a line of prior recorded information, count the number of spaces either in the entire line or in the right margin zone, and then varying the spacing of the interword spaces so that each line reasonably extends to the right margin. Other systems or variations of the immediately above described system type into the right margin zone and perform a carrier return at the first available space or, in one system, at the first syllable break if the operator has previously broken each word into syllables. In those systems which accomplish a carrier return at the last available interword space in the right margin zone, if no spaces are detected in thezone, the printer continues to print characters until the end of the zone. If the operator then wishes to hyphenate the word the operator must extend the typing beyond the right margin.
SUMMARY OF THE INVENTION The current invention is a highly improved right hand margin adjust feature for an automated typing system which performs editing functions throughout the typed material as well as the right hand margin and is responsive to a number of special characters such as sentence ending punctuation, tabs, hyphens, and line returns in addition to spaces and carrier returnsv In addition, the final copy may be typed in either normal style or legal style upon the choice of the operator.
The majority of standard automated type systems continue to type after the bell rings indicating the right margin zone, normally set six characters prior to the right margin. A carrier return is inserted upon the occurrence of a space in the previously typed copy. If no space occurs after the bell rings, the standard typing system fills the six spaces with characters and stops. In other words, if the last six characters consist of the words I am" the standard automated typing system would carriage return after "1 instead of after am, the normal carrier return if manually typed. Alternatively, if the last word were readable", the standard automated typing system would type readab" and stop rather than read and able on the next line.
The device of the instant invention stops at the bell ring, or when the right hand margin zone is entered, and looks at the remaining characters. If two interword spaces are present, a carrier return is inserted and the machine returns on the second space. If no spaces are present, the machine stops so that the secretary can hyphenate at her choosing. Thereafter, pressing a READ key only prints one character at a time. Therefore, when the operator reaches a syllable break, the operator can hyphenate the word and return the carrier.
Provision is also made for hyphens or spaces that must be kept regardless of carrier returns such as the hyphens in second-to-the-last". In order to maintain the hyphens with a standard automated typing system the operator is required to vary the typing pattern such as space, space, character, space, space, which is called a precedence code". Applicants use a "KEEP" key which, when depressed in conjunction with the appropriate character key, keeps carrier returns, tabs, spaces, and hyphens. This is often used, for example, for carrier returns in the address portion of a letter where only a quarter of a line if normally utilized.
Similarly, if in the body of a letter which is being edited there is a sentence ending punctuation mark followed by a carrier return, the edited version must be punctuated, the carrier return must be eliminated and two spaces must be added after the punctuation mark. A variation, of course, is where an abbreviation occurs, such as Dr. Smith". In that instance, the keep key would be pressed along with the space after Dr. so that no matter where it occurs there will be the period after Dr., only one space, and then the surname following. Finally, as discussed in the edit sequences described below, the system also functions based on information such as carrier returns or spaces immediately prior to the beginning of the right margin zone, this information being retained in memory units or counters of the device.
To achieve a proper sequence the system operates on an eight phase clock. The earlier phases of the clock are used to enable the edit or adjust function and to de tect which characters occur in the right margin zone. The latter phases of the clock are utilized for resolution of the changes in the orginal typed copy which are dictated by the right hand margin adjust feature.
Logical circuitry to accomplish the function of looking forward into the right margin zone comprise a zone insert memory and various flip-flops to indicate the beginning and end of the zone. Alpha numeric characters or other typing characters are analyzed in this system with a special character decoder, which reads data bits in selectric code from a buffer, and a zone recycling counter and a zone shift register memory unit which are combined to detect the occurrence of the editable special characters. Counters and flip flops are utilized to count spaces, carriage returns, line returns and as flags for tabs, sentence ending punctuation or hyphens.
Logical circuitry is then utilized to further evaluate the contents of the zone to determine the existence of the typing pattern prior to and in the right margin zone and to provide a predetermined resolution of the typing pattern in the right margin zone. As indicated above, if a word extends completely across the right margin zone and beyond the right margin, or upon special occurrences such as tabs or underlining, because these are unique to each document and cannot be automatically edited, this invention detects such as occurrence and automatically stops the system prior to proceeding further. Thereafter, the operator may choose the appropriate action and after initiating a carrier return the automated typing system with a right hand margin adjust feature will continue to perform in an automatic mode.
After analysis of the right hand margin zone the system functions to generate or delete spaces and/or carriage returns as required by the analysis and on succeeding phases of the eight phase clock initiates the typing system to edit the copy and record the revised copy, if desired by the operator. With this feature the finished copy can be typed and recorded in either normal form such as used on business letters or in legal form such as used on agreements or briefs or the like.
DESCRIPTION OF THE DRAWINGS FIG. I is a schematic diagram showing the electronic elements utilized in our invention for the detection of special selected characters;
FIG. 2 is a schematic diagram showing the electronic elements utilized in our invention for control of the special characters detected by the circuitry in FIG. 1; and
FIG. 3 is a flow chart showing the essential decision making steps of our right hand margin adjust feature to implement our invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT A primary function of the right hand margin adjust feature is to relocate spaces and carrier returns when the margins of a previously typed and recorded document have been changed or where an insertion or a deletion has been made to previously typed and recorded copy. To accomplish this function carrier returns in the initially typed copy must be deleted and replaced with one interword space or two interword spaces depending on the immediately preceding occurrence of sentence ending punctuation or not. Carrier returns which occur after sentence ending punctuation, such as a period, a question mark, a colon, or an exclamation mark must be deleted and replaced with two interword spaces. Carrier returns which would occur between two words in a sentence or after non-sentence endingpunctuation such as a comma or semicolon must be deleted and replaced with one space.
Since tabs on a typing system will not be set to accommodate the reformated or changed copy the automated typing system stops after the occurrence of a tab in order to allow the operator to position tabular columns as desired. In addition, since the format for a legal document employs additional carrier returns, as compared to normal typing, the subject invention is adapted to produce a legal format from a rough draft copy which is typed in normal style.
To accomplish these functions, provision is made by this invention to alter the following sequences which normally occur in originally typed and recorded information. The copy is reformated in the manner indicated which is suitable for either a normal typing style or a legal typing style. In the following tables a minus sign indicates that the typing function has been deleted and a plus sign indicates that the typing function has been added.
