In a camera of the drop-in loading type having a film insertion opening formed at the bottom of the camera body, a device is provided for restricting a back lid, supported for pivotal opening and closing movement on the camera, to a partially opened position where the insertion opening is exposed and a guide slot is defined between the camera body and the back lid for allowing a film container with a film leader previously drawn out to be inserted therethrough. The restricting device can be released for full opening in order that the back lid is full opened to a position where the rear of the camera body is exposed to allow repairing an interior mechanism.
