Abstract
An automatic document feeder includes a driving wheel, a clutch unit, and a plurality of roller units. The clutch unit is disposed in a housing unit, and includes a first wheel driven by the driving wheel, a second wheel for driving the roller units, a resilient member interposed between the first and second wheels for biasing the second wheel to move away from the first wheel, and a driving rod. The driving rod is movable between a connecting position whereat the second wheel engages the first wheel so as to allow for transfer of rotation between the first and second wheels, and a disconnecting position whereat the second wheel is disengaged from the first wheel so as to prevent transfer of rotation between the first and second wheels.
