Abstract
A print wheel selection mechanism operates to sequentially enter into a plurality of print wheels digits to be printed by initially entering the highest order digit into the lowest order or right-most print wheel or vice versa. During the next sequence, the highest order digit is shifted to the print wheel next to the right-most wheel, and the next order digit is entered into the right-most wheel. In this manner, the foregoing sequences are repeated until the entire number is entered into the print wheels with the number being sequentially entered and shifted along the several print wheels. The mechanism includes a plurality of intermediate stop wheels interdigitally and rotatably mounted on a common shaft with the print wheels, the print wheels and the intermediate stop wheels being urged to rotate in a predetermined direction. The print wheels and the intermediate stop wheels are each provided with stops for limiting the rotation of the next succeeding wheel in an ascending order.
