Abstract
A film cartridge has ah interior spring that first engages the leader of a filmstrip as the leader is initially wound into the cartridge housing and then is distorted from its original shape by further movement of the leader into the housing. When a door connected to the cartridge housing is closed, the spring is maintained distorted in engagement with the leader,opening the door frees the spring, allowing the spring to propel the leader from the cartridge housing by recovering its original shape.
