DRIVING SYSTEM OF PRINTING HEAD FOR PRINTER

摘要

PURPOSE:To dispense with a large capacity power source by preventing the lowering in power source voltage, by setting a carriage to a reverse mode corresponding to a wt. based on a printing data by a reverse mode judging and indicating part. CONSTITUTION:Printing data outputted from CPU1 is stored in a printing data memory part 2 and added to a printing data judging and indicating part 9 and a dot number/line calculating part 3. The wt. data calculated and operated by a wt. operating part 6 is added to a reverse mode judging and indicating part 4 and the moving direction of a carriage 8 is judged to output indication data to a carriage driving stage 7. The setting state of the carriage 8 to a predetermined position is judged on the basis of driving data to the printing data judging and indicating part 9 from the carriage driving stage 7 and needle data is outputted from the indicating part 9 while a printing head 11 is driven by a needle driving stage 10.
