Claim 1
Independent Claim
163 words
In a serial printer having carriage mounting means enabling lateral movement of a carriage assembly along a predetermined path, located in a first plane, the carriage assembly having a first carriage section mounted to said carriage mounting means and a second carriage section pivotally mounted to said first carriage section about a pivot line wherein said second carriage section is pivotable in a second plane substantially perpendicular to said first plane, the improvement comprising: a first member carried by a first side of said second carriage section, a second member carried by a second and opposite side of said second carriage section, and said first and second members engaging said carriage mounting means at respective locations which are laterally spaced from each other in the direction of said predetermined path, whereby unwanted pivotal movement of said carriage assembly with respect to an axis in the second plane is reduced while enabling pivoting of the second carriage section in the second plane when desired.
