Data input and processing apparatus having spelling-check function and means for dealing with misspelled word
First Claim
1. A data input and processing apparatus, comprising:
- a keyboard having a plurality of keys operable for entering character data indicative of characters, and word-separation data indicative of termination of entry of a word;
memory means for storing at least one set of entered word data indicative of a word represented by the character data entered through said keyboard;
a dictionary memory storing word data indicative of a multiplicity of words;
spelling-check means responsive to said word-separation data entered through said keyboard, for determining whether or not said dictionary memory stores the word data which is identical with the entered word data in said memory means which was entered last prior to the entry of said word-separation data, and for thereby determining whether or not a spelling of an entered word is correct; and
inhibiting means responsive to said spelling-check means, for inhibiting an operation defined by said word-separation data if said spelling-check means determines that the spelling of said entered word is not correct.

Abstract
A data input and processing apparatus as used in a typewriter, having a function of checking the spelling of entered words which are separated by word-separation data such as a space or a period. The apparatus has a device for inhibiting an operation defined by the word-separation data, e.g., a spacing movement to the next word, if the spelling-check device finds a misspelled word. Where there exists at least one numeral and/or symbol preceding or following the entered word, the numeral and/or symbol are ignored in checking the spelling of the entered data. When a misspelled word is found, the entered word is first erased, and then at least one candidate word which replaces the mispelled word is presented to the operator. The apparatus may have a plurality of operation modes including a candidate indication mode for displaying the candidate word, an ignoring mode for ignoring a misspelling alarm, a retyping mode for re-entering a correct word, and a correction mode in which the misspelled word is corrected in part by changing and/or deleting the characters.

8. A data input and processing apparatus for processing input data, comprising:
-
a keyboard having a plurality of keys for entering letter data indicative of letters, numerals and/or symbol data indicative of numerals and/or symbols independent of said letter data and attributes for modifying the characteristics of letter, numeral and/or symbol data; memory means for storing entered data entered through said keyboard, said entered data including numeral and/or symbol data which precedes and/or follows a series of character data indicative of successive characters; a dictionary memory storing multiple sets of character data indicative of multiple groups of characters; spelling-check means for disregarding said numeral and/or symbol data of the entered data which precedes and/or follows said series of character data, and determining whether or not the dictionary memory stores the set of character data which is identical with said series of character data, thereby determining whether or not a spelling of said series of character data is correct; misspelled-word indicator means for displaying, if said spelling-check means determines that the spelling of said entered word is incorrect, said entered word as a misspelled work, together with the numeral and/or symbol which is represented by the disregarded numeral and/or symbol data; candidate search means for retrieving from said dictionary memory at least one candidate word which replaces said misspelled word; and candidate indicator means for displaying said at least one candidate word, together with the numeral and/or symbol which is represented by the disregarded numeral and/or symbol data, if said entered data stored in said memory means includes said numeral and/or symbol data. - View Dependent Claims (9, 10)

11. A typewriter comprising:
-
a keyboard having character keys for entering character data indicative of characters, and word-separation keys for entering word-separation data indicative of termination of entry of a word, said word-separation keys including a space key for spacing adjacent words from each other, and a symbol key corresponding to a period; printing means for printing said characters as said characters are entered through said keyboard; memory means for storing entered data entered through said keyboard, said entered data including said character data; a dictionary memory storing word data indicative of a multiplicity of words; spelling-check means responsive to said word-separation data, for determining whether or not said dictionary memory stores the word data indicative of an entered word which is represented by said character data stored in said memory means and which has been printed by said printing means, and for thereby determining whether or not a spelling of said entered and printed word is correct; candidate search means for retrieving from said dictionary memory at least one candidate word which replaces said entered and printed word; commanding means for actuating said candidate search means to retrieve said at least one candidate word, after said spelling-check means determines that the spelling of said entered and printed word is not correct; erasing means responsive to said commanding means, for erasing said entered and printed word; and selector means which becomes operable, after actuation of the erasing means, but before completion of the erasure of said entered and printed word by said erasing means for selecting one of said at least one candidate word retrieved by said candidate word search means. - View Dependent Claims (12, 13, 14, 15, 16)

17. A typewriter comprising:
-
a keyboard having a character keys for entering character data indicative of characters, and word-separation keys for entering word-separation data indicative of termination of entry of a word, said word-separation keys including a space key for spacing adjacent words from each other, and a symbol key corresponding to a period; printing means for printing said characters as said character are entered through said keyboard; memory means for storing entered data entered through said keyboard, said entered data including said character data; a dictionary memory storing word data indicative of a multiplicity of words; spelling-check means responsive to said word-separation data, for determining whether or not said dictionary memory stores the word data indicative of an entered and printed word represented by said character data stored in said memory means, and for thereby determining whether or not a spelling of said entered and printed word is correct; alarm means for informing an operator of the typewriter that said entered and printed word is misspelled, if said spelling-check means determines that the spelling of said entered and printed word is not correct; erasing means for erasing said entered and printed word; display means for displaying said entered and printed word; mode selecting means operable if said spelling-check means determines that the spelling of said entered and printed is not correct;
said mode selecting means selecting one of at least one mode which includes an amending mode in which said entered and printed word is first erased by said erasing means, and then is corrected by changing and/or deleting at least one of the characters of the word displayed on said display means, and/or by adding at least one character to the displayed word, through said keyboard. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
