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). The degree of impression is controlled by an eccentric bearing (211) and the hammer can be adjusted for exact parallel engagement by moving plate (142) which pivots the hammer. The system is accuated by a geared drive train which rotates the eccentric cam (194) and causes the hammer to reciprocate.
