ABSTRACT:
A method and apparatus for loading a film cartridge in a camera frame having a cartridge chamber, a supply chamber, and a thumbwheel extending into the cartridge chamber. The film cartridge has a case, an internal spool, and a filmstrip attached to the spool. In the method, the film cartridge is positioned in the cartridge chamber with the spool axially adjoining the thumbwheel. A quill is placed in axial proximity to the spool of the film cartridge, opposite said thumbwheel. The quill is turned in a rewind direction for the spool. Rotating of the spool in the rewind direction is deterred. During the turning, the quill is urged into axial engagement with the spool and the spool is urged into axial engagement with the thumbwheel. Following the urging, a leading portion of the filmstrip is thrust out of the cartridge.
