Abstract
An improved mechanism for properly aligning a rotatable indicia carrying member and for locking said rotatable indicia carrying member in place. Both the aligning and locking mechanisms are formed as integral parts of a single frame unit and are operative to perform their respective aligning and locking functions during movement of the frame unit into engagement with the rotatable member.
