Abstract

An integrated plastic back lid for cameras is provided with a reinforcing metal plate firmly attached to the back lid for preventing the back lid from being deformed and a pressure plate for holding a film flat which is held resiliently by the reinforcing plate. For resiliently holding the pressure plate, resiliently deformable holding arms are integrally formed either on the pressure plate or on the reinforcing plate. The pressure plate and the reinforcing plate are assembled before being attached to the back lid.
