Abstract:
1. A scanning device comprising: a first image sensor module, the first image sensor module having a first image array sensor for scanning information from a first side of media; a second image sensor module, the second image sensor module being mounted opposite the first image sensor module so that the media can move to a scanning region between the first image sensor module and the second image sensor module, the second image sensor module having a second image array sensor for scanning information from a second side of the media; a housing attached to the second image sensor module the housing having a convex region, the housing moving the second image sensor module away from the first sensor module to accommodate thickness of the media; and a transport mechanism that moves the media into and through the scanning region between the first image sensor module and the second image sensor module, the transport mechanism then reversing direction of the media so that the media travels through the scanning region to exit the scanning region at a same location at which the media was first moved into the scanning region; wherein when latency in the transport mechanism reversing direction causes the media to travel so far outside the scanning region that the second image sensor module moves closer to the first sensor module, the transport mechanism causes the media to reenter the scanning region so that the media impacts the convex region of the housing causing the second image sensor module to move with respect to the first image sensor module and to thus provide sufficient separation distance between the second image sensor module and the first image sensor module to allow the media to reenter the scanning region.
