TRAVELING CYLINDER IMPRINTER HAVING SETTABLE TYPE WHEELS WITH THREE PERIPHERAL SECTORS

摘要

An imprinting device having a frame which mounts a form support bed. The frame also mounts a plurality of printing wheels above the bed. Each of the wheels has one peripheral segment with printing characters thereon, another peripheral segment with visually readable characters therein, and another peripheral segment with detent grooves. The wheels are settable to select desired characters for printing. A platen assembly is mounted beneath the bed and the platen extends through a slot in the bed. The platen assembly includes mounting members which mount the platen for shiftable movement between a printing position and an idling position. The mounting is such to move the platen to the printing position upon movement of the assembly in one direction and from one end and to an idling position upon movement of the assembly in the other direction from the other end. The device also includes an inked printing ribbon which is advanced incrementally upon each printing cycle of the platen assembly.
