Abstract
An article sensor for use with a conveyor having an article conveying surface includes a sensing member, a pivot which pivotally mounts the sensing member to pivot about a horizontal axis, and a bias which biases the sensing member above the conveying surface. The pivot is defined by a shaftless bearing which operates with an exceptionally small amount of friction which is substantially unaffected by side-loading placed on the bearing.
