Abstract
A camera comprises a chamber for receiving a film cartridge that contains a film spool having a spool end which is exposed to allow it to be engaged for rotation to wind a filmstrip into the cartridge, and a door for the chamber that covers the spool end. The door has a normally light-tight access opening arranged to be located over the spool end to permit a spool driver to be inserted through the access opening to engage the spool end for rotation to wind the filmstrip into the cartridge without having to open the door.
