Abstract

A media retraction system includes a loadstop shaft rotatable about an axis thereof, and a loadstop paddle rotatably coupled with and slidably mounted on the loadstop shaft such that the loadstop paddle is slidable about the axis of the loadstop shaft.

First claim

The invention claimed is:

1. A media retraction system, comprising:
a loadstop shaft rotatable about an axis thereof; and
a loadstop paddle rotatably coupled with and slidably mounted on the loadstop shaft,
the loadstop shaft including a channel defined by spaced supports extended from the loadstop shaft,
the loadstop paddle mounted within the channel and slidable relative to the loadstop shaft within the channel between the spaced supports about the axis of the loadstop shaft.

2. The system of claim 1 , wherein the loadstop paddle is slidable relative to the loadstop shaft about the axis of the loadstop shaft in a non-linear path.

3. The system of claim 1 , wherein a tip of the loadstop paddle is radially biased away from the axis of the loadstop shaft by a bias force.

4. The system of claim 3 ,
wherein, with rotation of the loadstop shaft and contact of the loadstop paddle with media, the loadstop paddle is slidable relative to the loadstop shaft against the bias force, and
wherein, with further rotation of the loadstop shaft and further contact of the loadstop paddle with the media, the loadstop paddle is slidable relative to the loadstop shaft with the bias force.

5. The system of claim 3 , wherein, with rotation of the loadstop shaft and contact of the loadstop paddle with media, the tip of the loadstop paddle is initially positioned at an inclined angle of contact to the media and is subsequently positioned at an orthogonal angle of contact to the media.

6. The system of claim 3 , further comprising:
a spring positioned between the loadstop shaft and the loadstop paddle to produce the bias force.

7. The system of claim 6 , wherein the spring contacts a portion of the loadstop shaft and a portion of the loadstop paddle.

8. The system of claim 1 , wherein the channel is oriented orthogonal to and radially offset from the axis of the loadstop shaft.

9. The system of claim 1 , wherein the loadstop paddle includes a slot formed in an outer side surface thereof and the channel includes a tab protruded from an inner side surface thereof, wherein the tab mates with the slot to slidably guide the loadstop paddle within the channel.

10. A media retraction system, comprising:
a cam gear member including a cam surface and gear teeth;
a loadstop shaft including a lever arm and gear teeth to interact with the cam surface and the gear teeth of the cam gear member to rotate and position the loadstop shaft, the loadstop shaft including a channel defined by spaced supports extended from the loadstop shaft; and
a loadstop paddle mounted within the channel of the loadstop shaft, the loadstop paddle to rotate with the loadstop shaft and slide relative to the loadstop shaft within the channel between the spaced supports.

11. The system of claim 10 , wherein the loadstop shaft is to rotate in a first direction to retract media, wherein the loadstop paddle is to rotate in the first direction with the loadstop shaft, and wherein the loadstop paddle is biased in the first direction within the channel.

12. The system of claim 11 , wherein, with rotation of the loadstop shaft in the first direction and contact of the loadstop paddle with the media, the loadstop paddle is to slide relative to the loadstop shaft within the channel in a second direction opposite the first direction.

13. The system of claim 12 , wherein, with further rotation of the loadstop shaft in the first direction and further contact of the loadstop paddle with the media, the loadstop paddle is to slide relative to the loadstop shaft within the channel in the first direction.

14. The system of claim 11 , further comprising:
a spring positioned between the loadstop shaft and the loadstop paddle to bias the loadstop paddle in the first direction, the spring positioned within the channel between the spaced supports.

15. The system of claim 14 , wherein the spring contacts a portion of the loadstop shaft and a portion of the loadstop paddle.

16. A media retraction method, comprising:
rotating a loadstop shaft having a loadstop paddle supported thereon about an axis, the loadstop paddle mounted within a channel defined by spaced supports extended from the loadstop shaft;
contacting media with the loadstop paddle during the rotating; and
with the contacting of the media, sliding the loadstop paddle relative to the loadstop shaft about the axis of the loadstop shaft within the channel between the spaced supports.

17. The method of claim 16 , wherein rotating the loadstop shaft includes rotating the loadstop shaft in a first direction, and wherein sliding the loadstop paddle relative to the loadstop shaft includes sliding the loadstop paddle in a second direction opposite the first direction against a biasing force acting on the loadstop paddle.

18. The method of claim 17 , wherein rotating the loadstop shaft includes further rotating the loadstop shaft in the first direction, and wherein sliding the loadstop paddle relative to the loadstop shaft further includes sliding the loadstop paddle in the first direction by the biasing force acting on the loadstop paddle.

19. The method of claim 17 , wherein the biasing force acting on the loadstop paddle comprises a spring positioned between the loadstop shaft and the loadstop paddle.

20. The method of claim 16 , wherein rotating the loadstop shaft includes moving the loadstop paddle between a non-obstructing position to allow media to enter a media path, a plurality of retracting positions to retract media into a media tray, and an obstructing position to prevent media from entering the media path.
