| description | A camera mechanism for cocking the camera shutter and metering the advancement of film is adapted to prevent metering prior to cocking of the shutter. The mechanism comprises a sensing pawl on a sensing slide which drops into a film perforation just prior to complete advancement of the film by a full frame and a metering pawl on a metering lever which moves to prevent further advancement of the film in response to movement of the sensing slide to a metering postion. Such movement of the sensing slide and consequent metering is prevented by interaction of the metering lever with the shutter high energy lever. Movement of the high energy lever to its cocked position frees the metering lever from engagement with the high energy lever and permits metering upon advancement of a film perforation into a position in which it engages the sensing pawl and moves the sensing slide to its metering position. |
