Document separator wheel and document hopper using the same.

摘要

A wheel (22) for reliable separation of the bottommost document in a stack (12) of such documents is formed of low friction material having formed therein a groove (34) of material of a high friction material so that rotation of the wheel (22) causes the groove (34) to engage an edge of the lowermost document in the stack (12) urging it toward an adjustable width throat (18) so that only a single document can pass therethrough, continued rotation of the wheel (22) allowing the document edge to snap over the high friction portion without resulting damage.
