JAM DETECTOR FOR AN INSERTER

摘要

A jam detector for use in an inserting station of an inserter. The jam detector including mechanism for (a) directing a horizontal light beam to traverse transversely the length of an envelope; (b) retroreflecting the light beam; (c) directing the beam toward a pair of opening fingers while the fingers are positioned for holding envelopes open; (d) sensory interruption of the light beam during an insertion cycle and (e) sensory uninterrupted retroreflection of each one of the light beam during an insertion cycle. The jam detector uses the two sensory mechanisms (d) and (e) to detect a jam in the inserting station during an insertion cycle.
