摘要:
A multiple paper sheet feed apparatus, suitable for use with a printer, comprises a plurality of sheet feed mechanisms each of which comprises a sheet feed roller and a clutch spring which selectively assumes either a first operation state for rotatively coupling the roller to the shaft, or a second operational state for releasing the rotative coupling. During rotation of a single sheet feed shaft common to all the feed mechanisms, solenoids corresponding to the respective clutches are selectively energized so that one or more corresponding armatures are disengaged from one or more associated clutch springs so as to cause the associated springs to assume their respective first states. As a result, one or more or all of the sheet feed mechanisms are rendered operative so that a selected one or more or all of the sheets are fed therethrough.
