Abstract
An accessory for use in an instant camera designed for standard film packs and by which the same camera can be used to expose and process self-processing film sheet assemblies of reduced image format size prepackaged in corresponding sized film packs. The accessory is in the nature of a U-shaped housing having exterior planar dimensions to complement the interior planar dimensions of a well in the camera for receiving a standard film pack. The U-shaped configuration of the housing defines a recess to receive and position the modified film pack of reduced size. The accessory carries movement transmitting relays by which actuation of a camera mounted switch is energized by insertion of the modified film pack and by which movement of a camera carried pick is transmitted to an accessory pick for initial ejecting movement of an exposed film sheet from the modified pack. The accessory pick is actuated preferably by a camera pick movement amplifier to accommodate the reduced exterior dimensions of the reduced format film sheet. Also, a viewfinder mask is provided as an adjunct to the accessory so that a viewed image will be collated with the reduced image format of film sheets in the modified film pack.
