Mechanically uncoupled setting drive for printer paper feed mechanism

摘要

The setting drive has a conical cogwheel (20), supported by a rotary axis (19), together with a cam disc (15). A perpendicular setting axis (21) carries a second, non-rotatable, conical cogwheel (24), displaced axially against a spring bias into engagement with the first cogwheel. The setting drive is uncoupled by displacement of a setting element (23), allowing rotation of the setting axis to bring it into a required angular position relative to the first rotary axis.
