Flat indicia wheels are used in conjunction with a Geneva-type register movement. The register utilizes transfer wheels which have an outer edge shaped to contain a plurality of scallops and cusps. Each transfer wheel is associated with a transfer disc that rotates about an adjacent shaft and whose transfer arm causes the transfer wheel to rotate a preselected angular distance by striking a peg attached to the transfer wheel. This type of movement makes possible the use of flat indicia wheels with indicia, or numerals, imposed on a flat surface of the wheel. The presentation of a flat numeral through an opening in a faceplate provides for easier reading and, when used with an automatic reading device such as a light pin, reduces the chances of an erroneous reading. |
