Abstract
A particular type camera requiring the exposed film to receive special handling at the photofinisher is adapted for use with a film cartridge which includes a film spool having an elongate coaxial hole open at one end of the spool and a readily fracturable element located within the coaxial hole. When the cartridge is loaded in the camera, a shaft member of the camera is received in the coaxial hole to fracture the fracturable element and thereby provide an indication to the photofinisher that the cartridge was used in the camera. Preferably, the shaft member is keyed to engage an integral rib of the film spool to rewind the exposed film into the cartridge.
