Abstract
A reloadable single reel film canister has a housing with first and second parts. The parts are movable, relative to one another, from a closed condition to an open condition. When in the open condition, a roll of film can be placed in the housing. When loaded with film the housing can be reclosed. The amount of film being withdrawn can be monitored by an encoder carried by the canister.
