Abstract

PURPOSE: To enable maintaining clear printing quality by providing a means to detect paper thickness in the paper feed passage of an impact printer and providing a mechanism which adjusts automatically a platen position and printing pressure suitably for the thickness.
CONSTITUTION: A paper thickness detecting mechanism 1 which detects paper thickness by a method to slide paper on a paper guide and detect optically the amount of movement of a roller moving shaft, or the like, is arranged in the paper feed passage of an impact printer, a control circuit 2 which calculates the amount of moving a platen positon corresponding to the detected paper thickness, a platen gap driving mechanism 3 which moves the gap of the platen by the calculated value and a hammer driving mechanism 4 which adjusts printing pressure according to the calculated value are provided. By so doing, paper thickness can always be detected and copy control and hammer pressure control can be performed automatically, therefore, clear printing quality is always secured.
