Patent ID: 11185161

Abstract:
A printer paper drawer door closing mechanism includes a fixed chassis defining a chassis plane, a lever arm joined to the chassis and pivotable about a lever arm pivot axis from a first lever arm limit state to a second lever arm limit state. A first bearing surface extends from the lever arm at a first lever arm distance and a second bearing surface extending from the lever arm at a second lever arm distance. The first bearing surface is at a bearing surface distance from the second bearing surface. An energy storage element is integrated with the lever arm. A cam plate is translatable toward and away from the lever arm and pivotable about a cam plate pivot axis from a first cam limit state to a second cam limit state. The cam plate includes a first cam surface extending from the cam plate and a second cam surface extending from the cam plate, the first cam surface being oriented at a positive angle relative to the copier chassis plane and co-planar with the first bearing surface, the second cam surface is oriented at a negative angle relative to the copier chassis plane and co-planar with the second bearing surface. The distance separating the first bearing surface and the second bearing surface is substantially equal to the distance separating a distal end of the first cam surface and a proximal end of the second cam surface.
