Abstract
A camera includes a chamber for receiving a film cartridge having a light-lock movable between open and closed positions, a chamber cover movable between a closed position covering the chamber and an open position uncovering the chamber, and manually operable means for releasing the chamber cover to move from its closed position to its open position. An ejector is provided for ejecting the film cartridge at least part way out of the chamber. An actuating member is sized and positioned such that it can be moved by the releasing means to both actuate the ejector to eject the cartridge from the chamber, and move the light-lock from its open to closed position.
Claims4
A camera comprising a camera body and a chamber for receiving a film cartridge having a light-lock rotatable between open and closed positions, is characterized by:
- a light-lock drive mechanism for rotating the light-lock between the open and closed positions, said drive mechanism including a spindle which engages the light lock, the spindle including a rotation stop which is engageable with a surface of the camera body to limit rotation of the spindle in a first direction;
- wherein said rotation stop is engageable with an additional surface of the camera body to limit rotation of the spindle in a second direction;
- and wherein said drive mechanism further includes a drive member engageable with the spindle to rotate the spindle, said drive member including a pin that is engageable with an arm of the spindle which, in combination with said rotation stop engaging said surface of the camera body, locks the spindle in an open position.
