Abstract

A chamber including a film cartridge compartment for cartridges including separate parallel reels and a narrow connecting portion through which the film carrying spaced measuring grooves can pass, between the reels, a winding assembly adapted for cooperating with one of the reels and to be animated of an oscillating movement, to provide a unidirectional movement of the film in front of a cartridge framing window, a sealing assembly, a trigger lever for actuating the sealing assembly, a plate of measurement articulated around a pivot point within the chamber, which allows a portion of the measurement plate to move along an arc-shaped path towards the binding portion of the film cartridge and away from it, a finger attached to said plate portion and arranged to be in contact with said film, a spring that pushes normally the tip of said finger against said film when said winding device is driven so as to penetrate into a measuring slot disposed at the edge of said film when said film has been moved to a position such that it substantially frames an unexposed portion of the film. In said window, and a first device actuated by said trigger lever to pivot said measurement plate around said pivot point in order to move said finger away from said slot after said shutter assembly has been actuated.
