Abstract
An endorser for document processing machines is provided with means for controlling the application of an endorsement in a manner which reduces the deleterious effects of impaction previously encountered when printing endorsements and at the same time affords certain other advantages. The system employs camming means operating through lever means to control the impact in a manner which converts a point load to a shear load while reducing power requirements to a driving motor and making it possible to cope with documents of varied thicknesses. The system makes it possible to convert some of the energy otherwise wasted in the system to accelerate the platen and thus reduce motor power requirements.
