IPC: G06F17/22
Filed: 1983-02-02
Abstract: PURPOSE:To realize a character procesing device which has a high conversion efficiency for all Kana (Japanese syllabary)-Kanji (Chinese character) conversion input data strings by selecting a kana-Kanji conversion processing emthod for every Kana-Kanji conversion input data string at every data string input time. CONSTITUTION:When the input from a keyboard 5 is supplied, an interrupt signal is sent to a microprocessor 1, and contro instructions stored in an ROM 12 are read out to perform various controls. First, whether Kana-Kanji conversion is started or not is decided, and the Kana input mode processing is performed if Kana-Kanji conversion is not started. If Kana-Kanji conversion is started, it is discriminated whether a parameter is designated or not. The control advances to the next step if the parameter is not designated, but parameter data is stored in a data register STPR if it is designated. The processing of each algorithm is executed by this value. Thus, Kana-Kanji conversion processins are performed in individually determined different methds by control instructions in the ROM 12.

A dot in lower outer circle setting mechanism 5 sets the dot in a range 51 on the inside of the outer circle on the raster image from the maximum valve 32 of the outer circle to coordinates exceeding the maximum value 34 of the inner circle. A dot in outer circle between circles setting mechanism 6 sets the dot in a range 61 between the outer and inner circles from the minimum value 35 of the inner circle on the raster image to the maximum value 34 of the inner circle. Thus, by setting bits in the ranges 41, 51, and 61, the exact ellipse can be drawn on the raster image.
