Abstract
An alignment mechanism for a paper tape reader in which the motor and drive sprocket assembly is firmly, but not rigidly, affixed to a base plate of the main reader unit by a plurality of compressive spring fasteners. Arcuate slots in a motor mounting base plate, in conjunction with spring-biased retainers projecting through those slots and secured to bosses on a reader base plate, maintain the two base plates in spaced parallel relation and permit limited angular rotation of the motor and drive sprocket assembly, thus facilitating angular adjustment of the motor. A bias spring applies a torsional force to the motor assembly, forcing it against an adjustable screw stop. Adjustment of this screw results in rapid and precise single-step alignment without the often disruptive further step of tightening retention fasteners.
