Abstract
Abstract An input circuit adapted to be connected to an electronic translator is disclosed. The input circuit comprises an alphabetical keyboard for inputting key code information representative of letters in an input word and a single symbol additive key switch for adding any one of several specific symbols to at least one of the letters. The specific symbol represents, for example, an inflection and is needed to completely represent the input word. A circuit for changing the coded input representing the at least one letter by adding thereto coded input representing the specific symbol is provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
321 words
An input circuit for an electronic translator wherein a first input word represented in a first language is entered to obtain a second word represented in a second language equivalent to the first word, said input circuit comprising: an alphabetical keyboard means comprising a plurality of letter keys, each letter key comprising means for entering key code information representative of a sole letter; a sole symbol additive key switch for adding any one of a plurality of different specific symbols to at least two of the letters entered by the alphabetical keyboard means, and changing means responsive to actuation of the alphabetical keyboard means and the symbol additive key switch for changing the key code of any one of the at least two letters entered by the alphabetical keyboard means to a key code representing a letter including one of said specified different symbols and said one letter, wherein said changing means comprises key strobe signal generator means for providing key strobe signals to the alphabetical keyboard means, said keyboard means acting upon said key strobe signals to provide said key code information; memory means for storing data corresponding to key code information representing said at least two letters; first means for determining when key code information input by said alphabetical keyboard means is the same as said data in said memory corresponding to said key code information representing one of said at least two letters; second means for generating information representative of any one of said plurality of different specific symbols in response to actuation of said sole symbol additive key switch; and third means responsive to said first and second means for combining said information representative of any one of said plurality of different specific symbols with the key code information representing said one of said at least two letters for forming a new type of code information representative of said one letter including one of said specific symbols.
Claim 2
Dependent Claim
321 words
An input circuit for an electronic translator wherein a first input word represented in a first language is entered to obtain a second word represented in a second language equivalent to the first word, said input circuit comprising: an alphabetical keyboard means comprising a plurality of letter keys, each letter key comprising means for entering key code information representative of a sole letter; a sole symbol additive key switch for adding any one of a plurality of different specific symbols to at least two of the letters entered by the alphabetical keyboard means, and changing means responsive to actuation of the alphabetical keyboard means and the symbol additive key switch for changing the key code of any one of the at least two letters entered by the alphabetical keyboard means to a key code representing a letter including one of said specified different symbols and said one letter, wherein said changing means comprises key strobe signal generator means for providing key strobe signals to the alphabetical keyboard means, said keyboard means acting upon said key strobe signals to provide said key code information; memory means for storing data corresponding to key code information representing said at least two letters; first means for determining when key code information input by said alphabetical keyboard means is the same as said data in said memory corresponding to said key code information representing one of said at least two letters; second means for generating information representative of any one of said plurality of different specific symbols in response to actuation of said sole symbol additive key switch; and third means responsive to said first and second means for combining said information representative of any one of said plurality of different specific symbols with the key code information representing said one of said at least two letters for forming a new type of code information representative of said one letter including one of said specific symbols.
Claim 3
Dependent Claim
45 words
The circuit according to claim 1, wherein said sole symbol additive key switch is adapted to be actuated subsequent to actuation of the alphabetical keyboard means for adding a symbol to said one of said at least two letters entered by the alphabetical keyboard means.
Claim 4
Dependent Claim
38 words
The circuit according to claim 1, further comprising display means connected to the changing means for displaying the complete first word including letters entered by said alphabetical keyboard means and symbols added by said symbol additive key switch.
Claim 5
Dependent Claim
52 words
The circuit according to claim 1, further comprising additional memory means coupled to an address counter means which is responsive to actuation of said alphabetical keyboard means for providing address information to said additional memory means, whereby said additional memory means stores each letter input by said alphabetical keyboard means in order.
Claim 6
Dependent Claim
21 words
The circuit according to claim 1, wherein the first language is selected from the group consisting of German, French and Spanish.
Claim 7
Dependent Claim
30 words
The circuit according to claim 5, wherein the specific symbol is selected from the group consisting of "umlaut" in German, "cedille" in French, "trema" in French and "tilde" in Spanish.
Claim 8
Dependent Claim
41 words
The circuit as in claim 1, wherein said alphabetical keyboard means comprises a plurality of keys for entering key code information representing a plurality of letters and said at least two letters comprise less than all of said plurality of letters.
