ABSTRACT:
A printing mechanism for use in an impact printing system primarily intended for the transfer of a dry film impression onto an image carrying tape. The mechanism includes a hammer (130), and an anvil (126). The hammer is actuated by lever arm (164) which is in turn accuated by eccentric cam (194). At its upper end the hammer is biased by a pivotal spring mechanism (152) against a roller bearing (162). At its lower end the hammer (130) has a guide pin (140) which passes through an aperture (144) in a guide plate (142). The guide plate is adjustably mounted by means of slots (141) so that movement of the guide plate adjusts the inclination of the hammer.
