PURPOSE:To use same consecutive Kanji (Chinese character) codes as an object of data compression by converting the most significant bit of the 2nd byte of the Kanji code comprising the 1st and 2nd bytes into '1'. CONSTITUTION:A Kanji code is inputted from a data input of a bit conversion section 1, the most significant bit of the 2nd byte is converted into '1' and the outputted. A storage section 2 stores a Kanji code 11 subject to bit conversion. then a comparison section 3 compares the Kanji code 11 with a Kanji code 11 stored in the storage section 2, and when only the 1st bytes are coincident, a coincidence signal 31 is outputted, and when both the 1st and 2nd bytes are coincident, a coincidence signal 32 is outputted. A counter section 4 receives the coincidence signal 32, its number of times is counted and the number of times 41 is outputted. The selection section 5 selects the Kanji code 11, the coincidence signals 31, 32 and the number of times 41 properly to output a data 51. Thus, the same consecutive Kanji codes are used as an object of data compression. |
