Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
251 words
A print timing apparatus for use in font belt printing for printing in accordance with the timing of any of a plurality of fonts having a different number of characters per set, each different font carried on a font belt, said font belt including a plurality of primary indicia and a plurality of secondary indicia, said primary indicia corresponding to each font on said belt and said secondary indicia corrEsponding to each character on a font, said first and second indicia positioned on said belt relative to each other in accordance with the size characteristic of each said font, said apparatus comprising a plurality of timing means for controlling the speed actuation of said printer in accordance with the size font on said font belt, a first sensor for sensing said primary indicia, a second sensor for sensing said secondary indicia, a counter coupled to said second sensor and responsive to each secondary indicia for accumulating a count corresponding to said sensed secondary indicia, said counter having a reset input further coupled to said first sensor and responsive thereto to be reset by each sensed primary indicia, the total count thus accumulated in said counter corresponding to a font size, decoding means coupled to said counter and responsive to each total level count accumulated in said counter for providing a unique output, and means coupling each unique output of said decoder to a corresponding one of said plurality of timing means for selecting one of said timing means of said printer.
