| 摘要 | A method and apparatus for characterizing Korean characters into compositional structure groups so as to provide for the automatic selection of individual symbol fonts used to formulate the various characters. A unique code is provided for each of the basic Korean symbols and logic circuitry is utilized to recognize basic compositional structure groups to provide a supplemental code for each symbol forming the Korean character. The supplemental code identifies the desired font. | ||||||
| 权利要求 | 1. A character converter for generating output signals indicative of a font for the basic symbols of a character from a set of coded input signals identifying each symbol comprising: a. a plurality of four stage shift registers for storing successive identifying coded signals, b. geometrical group classifying means connected to said plurality of shift registers for classifying said stored identifying signals into geometrical groups and for providing geometrical group output signals, c. control circuit means connected to receive the group output signals from said geometrical group classifying means, said control circuit means providing compositional structure output signals associated with each identifying coded signal, and d. output buffer means connected to receive said compositional structure output signals and said associated identifying coded signals, said control circuit means comprising: 1. means for generating a first control signal for shifting the stored identifying coded signals in the second stages of the plurality of shift registers into said otput buffer means, and 2. means for generating a second control signal for shifting the stored identifying coded signals in the third stages of said plurality of shift registers into said output buffer means. 2. means for generating a second control signal for shifting the stored identifying coded signals in the third stages of said plurality of shift registers into said output buffer means. 2. A character converter as recited in claim 1 wherein said control circuit further comprises a diode matrix. 3. A character converter as recited in claim 1 wherein said control circuit further comprises a read only memory. 4. A character converter as recited in claim 1 wherein the stages of each of said plurality of shift registers are connected to separate geometrical group identifying means. 5. A character converter as recited in claim 4 wherein said shift registers are connected to receive a parallel string of identifying coded signals. 6. A character converter as recited in claim 1 wherein said compositional structure groups comprises the groups: Cvv, CCvv, Chv, SVVb, SVVc, CVVb, CVVc, HVb, HVc, HVvv, vvCb, vvCCb, hvCb, hvCCb, and CChv. 7. A character converter as recited in claim 1 said converter further comprising: a. means connected to said storage means for identifying said stored coded signals as representing vowel and consonant symbols, b. means connected to said vowel and consonant identifying means for detecting a grammatically invalid succession of successively stored vowel and consonant coded signals, and c. means for generating an error signal upon the occurrence of a grammatically invalid succession of stored coded signals. 8. A character converter as recited in claim 7 wherein said coded input signals comprise a distinct identifying code for distinguishing vowels and consonants. 9. A character converter as recited in claim 1 wherein said compositional structure groups comprise the groups: Csvv, CCsvv, Ccvv, CCcvv, Cdhv, CCdhv, Cuhv, CCuhv, Chvv, CChvv, SVVb, SVVc, CVVb, CVVc, HVb, HVc, HVvv, vvCb, vvCCb, hvCb, and hvCCb. |
