ABSTRACT:
A microfilm camera is provided which has a camera head positioned above an exposure table. The exposure table included a pivotable glass plate and originals to be photographed can be placed beneath the glass plate or on its upper surface. To enable in-focus pictures of originals in either position to be taken, means are provided to vary the distance between the film in the camera head and the glass plate. In one embodiment the exposure table is mounted on four columns each having a lifting cam operated by a common activating handle. In a second embodiment the camera head can be raised or lowered by a handle operated eccentric cam.
