ABSTRACT:
A web positioning system, particularly usable for use in a hand-held labeler employing a thermographic print head, utilizes a circular indexing member having a plurality of position defining indices for providing indications representative of the position of the web. The circular, and relative rotation between the circular member and the shaft is prevented by a plurality of key slots or the like disposed on said circular member and engaging a key, and slot or the like on the shaft. The angular spacing between the key slots is unequal and is substantially greater than the spacing between the position-defining indices; but the position of the position defining indices relative to the shaft may be adjusted by a distance less than the distance between the position defining indices by bringing a different one of the key slots into engagement with the shaft.
