摘要

The frame assembly is provided that includes a frame (12) having a cartridge chamber (14), a supply chamber (16), and an intermediate section between the chambers. The frame assembly includes a thumb-wheel attached in freely rotatable relation to the frame. The thumb-wheel (94) has a rotation member disposed external to the cartridge chamber and a drive-key extends axially into the cartridge chamber. A film cartridge is positioned in the cartridge chamber in close axial proximity to the thumb-wheel drive-key. The film cartridge includes a spool and a film strip. The spool has opposed first and second ends. Each end has a spool engagement portion. The spool engagement portion of the first end is complementary in shape to the thumb wheel drive key. The film strip has leading, main and tail portions. A quill drive key (110) is placed in close axial proximity to the second end of the spool. The quill drive key is complementary in shape to the spool engagement portion of the second end. The thumb wheel is clamped. The quill drive key is rotated. During the rotating, the quill drive key is urged axially toward the cartridge, which is urged toward the thumb wheel drive key, until both drive keys mate engagingly with respective engagement portions.
