Film loading method for a single use APS camera

In a camera of the type that employs a film cassette having a light lock door that is movable between open and closed positions, the camera having a main body, a back cover securely attached thereto, a film cassette compartment on one end, a rotatable spool with a film receiving slot on the other end, a film path extending between the film cassette compartment and the spool, a film cassette loading port for loading the film cassette into the film cassette compartment, rotatable advancing means for advancing film between the film cassette and the spool, a method comprising the steps of:

• i) loading the film cassette into the film cassette compartment via the film loading port with the light lock door closed, the advancing means engaging a light lock door actuator inside the film cassette;
• ii) rotating the advancing means in a first direction to open the light lock door;
• iii) preventing further rotation of the advancing means from operating the light lock door actuator;
• iv) continuing to rotate the advancing means in the first direction to drive film out of the cassette, across the film path and into the film receiving slot;
• v) winding film from the cassette onto the spool;
• whereby the camera is pre-loaded with the back cover, in place the camera being adapted to take exposures, one frame at a time, by rotating the advancing means in a second direction opposite to the first direction to withdraw film back into the cassette.
