Abstract An improvement in an electrophotocopying machine having a reciprocating carriage driven by a constant speed chain having a drive pin coupled thereto. The improvement comprises a camming yoke fixedly connected to the reciprocating carriage and disposed in a plane parallel to the plane of the constant speed chain, the camming yoke having an opening therein to receive the drive pin. The opening is defined at its top and bottom by extended, substantially horizontal camming surfaces and at its sides by substantially vertical camming surfaces.
