Abstract
PURPOSE: To simplify the adjustment of printing pressure, and to lengthen the life of a type carrier by a method wherein a movable section of a printing hammer is divided into two or more sections, and each driven independently in the impact type type printer.
CONSTITUTION: A printing head 13 giving the type of a petal, etc. type head striking force from the back has structure similar to a dot matrix type printer head. For example, seven wires 53 are driven by attracting armatures 52 by electromagnets 51. In this case, the number of the magnets 51 excited is selected in response to the shape of the type to be printed, and impact force at the time of the striking of the type is changed. In case of characters M, W, printing areas thereof are large, and a symbol @, for example, seven wires aWg are selected. The impact force is adjusted in response to the size of characters as six wires in characters B, D..., etc., five wires in characters A, C..., etc., etc.
