发明名称 Vacuum feeder for imaging device
摘要 Media is transported to an imaging region using a vacuum feeder. A vacuum head is positioned onto the media and a vacuum is applied to the vacuum head to hold the media against the vacuum head. The vacuum head is then relocated to the imaging region carrying with it the media. In one embodiment, the vacuum head holds the media slightly above the surface of the imaging region. After the media is imaged, the vacuum head moves the media to an output region. In the output region the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the output region. In another embodiment, the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the imaging region. A second vacuum head is positioned in the imaging region onto the media and a vacuum is applied to the second vacuum head to hold the media against the second vacuum head. The second vacuum head is then relocated to the output region carrying with it the media. The second vacuum head moves the media to an output region. In the output region the vacuum is removed from the second vacuum head allowing the media to detach from the second vacuum head and remain in the output region.
