Printing mechanism with print hammer having noise dampener.

摘要

A printing device including a print hammer having a noise dampener for use with an impact printer mechanism. The print hammer has a significant mass for impacting a character pad against an ink ribbon, paper and a platen. In a first embodiment the print hammer includes an acoustic noise dampening layer interposed between a mass weight and the hammer face which carries the anvil that impacts during printing. In other embodiments the print hammer is formed in two parts. One part having a weighted mass and the other part being pivotally coupled to the printer mechanism. The two parts are structurally joined together by a noise dampening member. Transmission of acoustic noise during impact printing through the hammer is reduced. <IMAGE>
