Blattsteuermechanismus zur Nutzung in einem elektrophotographischen Druckgerät

An apparatus for advancing a sheet (25) in a predetermined path is described. The apparatus includes a mechanism (48-76) for advancing the sheet (25) in the path. The apparatus further includes a first mechanism (84, 102) for controlling movement of the sheet (25) while it is being advanced in the path, the first controlling mechanism (84, 102) being in contact with the sheet (25) in a first mode of operation and being spaced apart from the sheet (25) in a second mode of operation. Moreover, the apparatus includes a second mechanism (129) for controlling movement of the sheet (25) while it is being advanced in the path, the second controlling mechanism (129) being in contact with the sheet (25) in a first mode of operation and being spaced apart from the sheet (25) in a second mode of operation. The apparatus additionally includes an intermediate member (124) movable between a first location and a second location, each of the controlling mechanisms (84, 102, 129) being positioned in one of its respective modes of operation in response to the intermediate member (124) being positioned at its first location and being positioned in the other of its respective modes of operation in response to the intermediate member (124) being positioned at its second location.
