Abstract
A print hammer mechanism 10 includes a plurality of parallel print hammers positioned for sliding movement within slots 20a-i, 22a-i in the walls 16, 18 of a frame 12. The selective energization of one of a plurality of magnets 61a-i draws the corresponding hammer 30a-i against a rotating roller 52. The roller 52 drives the print hammer from a rest position to a print position. At the print position, a head 40a-i on the selected hammer 30a-i forces a paper medium against a type die 64 with an ink ribbon 62 interposed. Return movement is provided by a coil spring 38a-i attached to the rearward end of the hammer 30a-i.
