ABSTRACT:
A compact viewer having an active display belt supported for movement around an endless loop and a projection station for scan-exposing successive image portions, from the image medium to be viewed, onto successive portions of the belt where they are temporarily stored for viewing. In a preferred embodiment images are selectively scan exposable at opposite sides of the viewing station to facilitate bidirectional image retrieval. An erasure station is provided along the belt path at a location spaced from the viewing station to prepare the belt for display of new images.
