ABSTRACT:
A particular type camera requiring the exposed film to receive special handling at the photofinisher has a loading chamber for receiving a conventional film cartridge in an axial direction. A back door of the camera is supported for closing movement to cover a film cartridge received in the loading chamber and for opening movement to permit the received cartridge to be removed in an axial direction from the chamber. An encoding means mounted on the back door has a finite range of influence within which the received cartridge is encoded with a detectable code mark to identify the cartridge to the photofinisher as one that was used in the particular type camera. Preferably, the encoding means is a magnet for magnetizing a macroscopic region of the received cartridge to encode the cartridge with a macroscopic magnetic field having a predetermined orientation. The magnet moves with the back door towards the received cartridge at least until the cartridge is within the finite range of the magnet, to encode the cartridge with the macroscopic magnetic field, and moves with the door away from the received cartridge at least until the cartridge is outside the finite range of the magnet, to permit the cartridge to be removed in an axial direction from the loading chamber without the magnet altering the encoded magnetic field.
