ABSTRACT:
A mechanism for inserting a flat object into a processing device for processing the object, the processing device including a fixed frame having an insertion slot via which the object is inserted, the slot forming a passage having a wall which is perpendicular to the surface of said flat object, and which serves as a reference abutment surface for one side of said flat object, the mechanism being wherein the mechanism includes two wheels, each of which penetrates into the slot via a respective aperture, at least one of the wheels being mounted at the end of a rocker arm whose other end is mounted in a cradle to pivot about a rocking axis that is parallel to the direction F in which the flat object is inserted, wherein the cradle is in turn mounted in the fixed frame to pivot about a swivel axis that is perpendicular to the plane of the insertion slot, wherein resilient elements apply a certain pressure to press the wheels together, and wherein an abutment delimits the swivelling stroke of the cradle about the swivel axis.
