Abstract
Abstract A plurality of feed shafts associated respectively with paper tape, record card and ribbon feed means are cooperably coupled with a tri-planed driven gear of a Geneva-type gear system, the driven gear being mountably and cooperably engaged with a triplaned driving gear which is belt connected to an electric motor for continuous rotation therewith, the various planes of the driving and driven gears being so configured as to produce a predetermined number of positively controlled increments of antibackup rotation of the driven gear for each complete revolution of the driving gear and to thereby incrementally feed an inked ribbon, a paper tape, and/or a record card in a printing device such as may be utilized in a business machine or in a terminal unit for a computer system, the tri-planed arrangement of the two gears providing a smooth meshing and unmeshing of the teeth thereof and serving to distribute the driving and driven loads of the two gears as between the teeth arranged on the three planes thereof.
