Abstract
Abstract An illuminating assembly for illuminating an article such as a sheet located on a light-permeable support which forms a part of a structure used in connection with making microfilm photographs. The structure includes a light-permeable plate through which the light passes to reach the article which is to be illuminated, and on one side of this plate is situated a reflecting wall for reflecting light to the plate. A plurality of light sources extend at least in part to the side of the wall which is directed away from the plate, and a plurality of reflecting means respectively coact with the light sources for screening the latter against transmitting light directly to the plate while reflecting light therefrom to the wall to be reflected by the latter to the plate. An adjusting means is connected with the reflectors for adjusting the distance thereof with respect to the light-reflecting wall.
