ABSTRACT:
A camera for perforated roll film includes a transport mechanism for advancing film along an exposure plane, a metering lever spring biased from an inactive toward an active position to disable the transport mechanism, and a sensing member for detecting the arrival of a perforation in the film at a predetermined position. The metering lever engages the film sensing member and biases the film sensing member into contact with the film. Sensing of a perforation and subsequent movement of the sensing member to a metering position disengages the sensing member from the metering lever and permits movement of the metering lever to its active position. Exposure operation of the shutter actuating mechanism returns the metering lever to its inactive position. A spring acting substantially parallel to the exposure plane is operative to return the sensing member to its sensing position upon subsequent operation of the film transport mechanism.
