Abstract

PURPOSE: To adjust the impact force of a hammer efficiently through simple control by a method wherein a hammer section of a printing mechanism is divided, and driven separately, in the impact type printer.
CONSTITUTION: A partition type printer head 13 has structure similar to a dot matrix type printer head. For example, seven wires 53 are each driven by exciting corresponding electromagnets 51. In this case, the number of the magnets 51 excited is selected in response to the shape of type to be printed, and a character table 71 selecting the wires 53 driven by the kinds of the type is set in order to control the impact force of the hammer. Accordingly, when a printing code is inputted to a driving hammer selective circuit, output signals 71aW71g for driving the wires 53 are selected on the basis of the character table 71, and the electromagnets 51 are selected and driven through AND gates 73aW73g and drive circuits 74aW74g.
