ABSTRACT:
Improved apparatus is provided in a viewer of the type having a film cassette receiving well defined in part by an opening in the viewer and an interior sidewall extending perpendicularly inward of the opening and from which extend outwardly a pair of drive heads. The improved apparatus is provided to guide the edge of the leading end wall of a cassette, as it enters the receiving well, past the pair of drive heads and ultimately into nesting relation adjacent the sidewall with the drive heads engaged to complementary recessed drive couplings in the side of the cassette upon complete insertion of the cassette into the well. The improved apparatus not only accommodates the ready insertion of the cassette within the receiving well, but also accommodates the ready removal of the cassette from the well by resiliently urging the bottom of the cassette to move in a direction outward of the cassette receiving well.
