Abstract:
1. An apparatus comprising: a drum configured to carry a sheet and rotate about an axis; a first claw opposite the drum and configured to move between a sheet ejecting position and a non-ejecting position; a cam coupled to the drum and configured to rotate about the axis; and a cam follower operably coupled to the first claw, wherein the first claw moves between the ejecting position and the non-ejecting position in response to engagement of the cam follower with the cam; an actuation mechanism operatively coupled to the cam follower and configured to move the cam follower between a cam engaging position and a cam disengaging position; a second cam spaced from the drum and having a first surface; and a second cam follower operably coupled to the first claw, wherein the cam follower moves between the cam engaging position and the cam disengaging position in response to engagement of the second cam follower with the first surface of the second cam, wherein the second cam includes a second surface oblique to the first surface and wherein the first claw moves from a first position having a first non-zero spacing from the drum to a second position having a second non-zero spacing from the drum greater than the first non-zero spacing in response to the second cam follower moving from the first surface to the second surface.
