Apparatus (10) and methods are disclosed for loading a camera frame (100) for subsequent inclusion in a single-use camera, the camera frame including an exposure opening (102), a chamber (104) on one side of the exposure opening for receiving a light-tight film cartridge (18) enclosing a spool (19)

Apparatus (10) and methods are disclosed for loading a camera frame (100) for subsequent inclusion in a single-use camera, the camera frame including an exposure opening (102), a chamber (104) on one side of the exposure opening for receiving a light-tight film cartridge (18) enclosing a spool (19) to which is attached a trailing end of a filmstrip (36), and a chamber (108) on an opposite side of the exposure opening for receiving a scroll (268) formed from the filmstrip. The apparatus may include a device (28) for holding a cartridge; a mechanism (32, 34) for withdrawing a leading end (38) of a filmstrip from a cartridge; a mechanism (68-78; 190-192) for positioning a retainer cap near a free end of a scrolling quill, the retainer cap including abutment means for engaging an end of a scroll to prevent clock-springing and means for permitting the filmstrip to pass the abutment means during formation of a scroll; a mechanism (60-66; 300-320) for engaging a leading end around a scrolling quill (56,256-262); a mechanism (48-54; 58, 270-284) for removing the scrolling quill from a scroll; and a mechanism (86-98; 120-178; 120′-170′, 180, 182) for installing a cartridge into the first receiving chamber and a scroll and retainer cap into the second receiving chamber, whereby a portion of a filmstrip will extend across the exposure opening between a cartridge and a scroll. Corresponding methods are disclosed.

A method for loading a camera frame for subsequent inclusion in a single-use camera, the camera frame including an exposure opening, first means on one side of the exposure opening for receiving a light-tight film cartridge enclosing a spool to which is attached a trailing end of a filmstrip, and second means on an opposite side of the exposure opening for receiving a scroll formed from the filmstrip, the method comprising steps of: withdrawing a leading end of the filmstrip from the cartridge; positioning a retainer cap near a free end of a scrolling quill, the retainer cap including abutment means for engaging an end of a scroll to prevent clock-springing and means for permitting the filmstrip to pass the abutment means during formation of a scroll; passing the leading end through the means for permitting; winding the leading end around a scrolling quill and into the retainer cap; continuing the winding to form the filmstrip into a scroll of film around the scrolling quill, an end of the scroll being within the end cap, while leaving the trailing end attached to the spool within the cartridge; after winding the scroll, removing the scrolling quill from the scroll; and after removing the scrolling quill, installing the cartridge into the first means for receiving, and the scroll and retainer cap into the second means for receiving, whereby a portion of the filmstrip extends across the exposure opening between the cartridge and the scroll.
