ABSTRACT:
A business machine including a frame, a paper support mechanism and a printing mechanism for successive character printing on paper supported from the paper support mechanism is provided. One of the mechanisms is supported from the frame for guided incremented shifting relative to the other mechanism whereby successive printed characters made on paper supported from the paper support mechanism by the printing mechanism will form a line of printed characters extending along the paper in a predetermined path. An incremental advance structure including first and second indexing components supported from the frame and the aforementioned one mechanism is also provided and is operatively connected between the frame and the aforementioned one mechanism for advancing the latter to successive predetermined incremental positions of movement along the aforementioned path responsive to successive actuation of the printing mechanism and with such incremental positions of movement corresponding to predetermined positions on the paper support mechanism. Adjustment structure is provided supporting the first indexing component from the frame for infinite variable positioning relative thereto in a direction generally paralleling the aforementioned path. The adjustment structure includes a threaded connection between the first indexing component and the frame whereby the precise desired positioning of the first indexing component relative to the frame may be effected.
