Abstract
Various embodiments of a duplexer are disclosed in which a guide directs a sheet to a first transport which continues to move the sheet in a first direction or moves the sheet in an opposite direction to subsequently overturn the sheet.
Claims21
A duplexer system comprising:
- an input;
- a path extending from the input and configured to overturn a medium;
- an interaction device adjacent the path;
- a first transport configured to move the medium in a first direction away from the interaction device and a second direction opposite to the first direction without disengaging the medium;
- and
- a guide configured to direct the medium being moved in the second direction by the first transport to the input, wherein the guide is configured to pivot between a first position in which media is directed from the interaction device to the first transport and a second position in which media being moved by the first transport in the second direction is directed to the input;
- an actuator operably coupled to the guide and configured to pivot the guide between the first position and the second position;
- and
- a second transport configured to move in a third direction to move the medium from the interaction device towards the first transport and a fourth direction to pivot the guide from the first position to the second position.

A duplexer accessory for use with an interaction system having a path extending from an input having a feed tray and a pick device, the interaction system being configured to overturn media and an interaction device along the path, the accessory comprising:
- a transport configured to move a medium in a first direction away from the interaction device and a second direction opposite to the first direction without disengaging the medium;
- and
- a guide configured to direct the interacted upon medium to the transport and to guide the media being moved by the transport in the second direction towards a position in which the media is contacted by the pick device, wherein the guide pivots between a first position and a second position and wherein the guide is configured to be operably coupled to an actuator of the interaction system to pivot the guide between the first position and the second position;
- and
- a roller operably coupled to the actuator so as to be rotated by the actuator, wherein the roller is connected to the guide by a slip clutch.
2 more elements
A duplexer system comprising:
- an input including a feed tray and a pick device opposite the feed tray;
- an exterior housing having a face;
- a first opening along the face through which media is loaded into a position opposite the pick device;
- a second opening along the face through which a medium is discharged;
- a path extending from the input and configured to overturn the medium;
- an interaction device adjacent the path;
- a first transport configured to move the medium in a first direction away from the interaction device and a second direction opposite to the first direction without disengaging the medium;
- a guide configured to direct the medium being moved in the second direction by the first transport to the input;
- an actuator;
- and
- a roller operably coupled to the guide and configured to be driven by the actuator in a first direction to move the medium towards the first transport and in a second direction to pivot the guide.
