Ejecting windowed and non-windowed media
View Patent ↗An infeed module of a valuable media depository is configured to track media edge detection during ejection processing. When sensors of the infeed module report conditions that would otherwise indicate that media has exited or been retracted back into the infeed module during ejection processing, reporting of the conditions are delayed or modified based on a tracked edge detection status. Thereby permitting the infeed module to perform proper ejection processing on both windowed and non-windowed media regardless of the dimensions present for any windowed portions of the media.
1. A method, comprising:
(i) disabling media edge detection processing during ejection processing by a media ejection controller for media being ejected from an infeed module, wherein the media ejection controller tracks directions of movement of the media based upon signals from first and second sensors during media edge detection;
(ii) enabling the media edge detection processing by the media ejection controller when a shutter opens for the infeed module based on detection of the media at the first sensor, wherein the first sensor is closer to the shutter than the second sensor; and
(iii) determining by the media ejection controller whether the media has exited the infeed module or whether the media has been fully retracted back within the infeed module based on signals from the first and second sensors produced during the media edge detection processing.
2. The method of claim 1 , wherein (i) further includes activating a media transport to urge the media along a transport path until the first sensor reports a blocked condition and then opening the shutter and halting the media transport by the media ejection controller.
3. The method of claim 2 , wherein activating further includes activating the media transport to urge the media along the transport path a present distance and stopping the media transport.
4. The method of claim 3 , wherein (ii) further includes (a) setting a media status to: “media at both of the sensors” by the media ejection controller when the first sensor and the second sensor are both reporting the blocked condition, wherein the media status represents a current condition for the media within the infeed module based on current information being reported by the media sensors.
5. The method of claim 4 , wherein (ii) further includes (b) changing the media status to: “media being retracted into the infeed module” by the media ejection controller when the first sensor reports an unblocked condition while the second sensor is reporting the blocked condition.
6. The method of claim 5 , wherein (ii) further includes (c) maintaining the media status unchanged by the media ejection controller when the first sensor continues to report the blocked condition while the second sensor reports the unblocked condition until the first sensor reports the unblocked condition and then changing by the media ejection controller the media status to “media exited” indicating the media has exited the infeed module.
7. The method of claim 3 , wherein activating further includes (iv) delaying for a present delay period of time for determining whether the media is removed from an infeed mouth of the infeed module.
8. The method of claim 7 , wherein (iii) further includes delaying an additional period of time by the media ejection controller when a media status is permitted to change at an end of the present delay period to “media exited”, and when the media status remains unchanged determining by the media ejection controller that the media has successfully ejected from the infeed module and when additional media is present for ejecting from the infeed module returning to step (i), wherein the media status represents a current condition for the media within the infeed module based on current information being reported by the media sensors.
9. The method of claim 8 , wherein (iii) further includes determining by the media ejection controller whether either the first sensor or the second sensor report the blocked condition during any portion of the additional period of time and when determined to be the case returning to step (iv).
10. The method of claim 7 , wherein (iii) further includes disabling the media edge detection processing by the media ejection controller when the media status remains unchanged at an end of the present delay period, and activating by the media detection controller the media transport to urge the media back into the infeed module in a direction away from the shutter for a distance that is less than a present distance, enabling by the media ejection controller the media edge detection processing while activating the media transport, halting the media transport by the media ejection controller when the media status changes to “media entered”, and returning to step (i).
