Abstract
A cuvette to reveal rolls of photographic film, which is essentially characterized in that its reel roll holder presents one of its plates adjustable on its axis at different distances from the upper plate, eligible at will and perfectly stable once adjusted; with the possibility of rotating angularly within fixed limits with respect to the axis and the upper plate; both plates being provided, by their respective internal faces, with respective spiral-shaped tabs serving as guide and containment to the edges of the roll; and for presenting in the access or external start of one and the other spirals, a retention device solved by a steel ball displaceable to right and left according to the line of the spiral.
