Heat sensitive recording system

Abstract

Abstract PURPOSE:To provide a recording system which can improve the utilization efficiency of a power source capacity with the acceleration of a printing by covering as many sections as possible simultaneously in printing one line as long as the total number of heat generating bodies simultaneously energized does not exceed a specified value. CONSTITUTION:Printing circuits P1-P5 control the energization of heat generating bodies A1-Amn each belonging to sections B1-Bm separately according to printing control signals d1-d5. The heat generating bodies A1-Amn are lined up in the main scanning direction while the max. number of the heat generating bodies simultaneously energized is set at (k+n-1). At the same time, before the printing of one line, the distribution of black drawing element in the line involved is checked to ensure that the printing covers as many sections B1- Bm as possible simultaneously within such a range as to hold the total number of the heat generating bodies energized simultaneously within (k+n-1).
