ABSTRACT:
A reproducing apparatus having a plurality of modes of operation. The apparatus includes a moving imaging surface. In a first mode of operation a stationary document is viewed and an image thereof is projected onto the imaging surface. In a second mode a document moving at a first speed synchronized to the speed of the moving imaging surface is viewed, and an image thereof is projected onto the imaging surface at a desired magnification. In a third mode a document moving at a second speed synchronized to the speed of the moving imaging surface is viewed and an image thereof is projected onto the surface at a reduced magnification. An arrangement for selecting the desired mode of operation is provided.
