Photographic camera with light seal/latch device for loading door

A photographic camera comprises a camera body, a cartridge receiving chamber located inside the camera body, a door connected to the camera body for closing and opening movement to cover and uncover the chamber, and latching means connected to the camera body for locking and unlocking movement to lock the door closed and to unlock the door. According to the invention, actuating means connects the door and the latching means for initiating opening movement of the door in response to unlocking movement of the latching means and for initiating locking movement of the latching means in response to closing movement of the door. Preferably, the latching means includes a light sealing collar for the door which is shaped to partially surround the door when the door is locked closed to prevent ambient light from leaking under the door into the cartridge receiving chamber.
