Patent JP-S57176177-A (JP)
Title: Serial printer
Inventor: MASAKI HIDEO
IPC: G06K15/10
Filed: 1981-04-24
Abstract: PURPOSE:To increase the printing speed of a serial printer when it prints a mixture of Chinese characters, Kana (the Japanese syllabary) and blanks (space) by determining the moving speed of its carriage which prints English alphabet, numerals, and kana characters based on such a character which has a less number of blank (space) to be placed before or after the character. CONSTITUTION:When a kana charater is to be printed from the first column, 5 columns of blank information b are memorized as it is the beginning of a print line, and plural number f information A indicating the printing of a kana from the first column are continuously memorized, and the one column of blank information b is memorized and plural number of information KG indicating the printing of Chinese character are continuously memorized. For convenience sake, the example shown in the figure shows such a case wherein the length of memory area of blank information b and that of kana character information A and Chinese character information KG are in the ratio of 2 to 3. Since the number of blank before kana character information A is 5 and that of blank after the A is 1, kana character printing speed is determined based on a case wherein the number of blank is less, in other words the number of blank is one, and it is determined as VA1.
