Printer cabinet

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.

Print hammer mechanism

An assembly for processing paper tape for data processing and communication applications. The punch and reader are in a common housing which includes a self contained chad box. The assembly has a substantially flat bottom surface thus permitting the assembly to be mounted on a table. The entire operating mechanism is arranged such that it is mechanically isolated from the housing. The punch and reader assemblies utilize identical paper drive assemblies which are mechanically linked by a rigid bar. The one drive assembly is driven from an eccentric which in turn is driven by a flexible belt coupled to a motor pulley.
