• clutch-coupling means for clutch coupling said additional number wheel to said drive shaft;
• a first alignment star corresponding to said first number wheel and an additional alignment star corresponding to said additional number wheel;
• and, a cam mechanism for aligning said number wheels including:
• a rotatable cam shaft having a first cam disc and an additional cam disc mounted thereon;
• a first pawl mounted so as to be actuable by said first cam for engaging said first alignment star to align said first number wheel when said cam shaft is rotated;
• and, an additional pawl mounted so as to be actuable by said additional cam for engaging said additional alignment star to align said additional number wheel when said cam shaft is rotated;
• said cams being mounted on said cam shaft so as to first cause said additional pawl to engage said additional alignment star, and then, to cause said first pawl to engage said first alignment star when said cam shaft is rotated.
