Abstract
A counting device in a still camera for indicating the exact number of frames of long-footage film exposed during regular photography includes a numerical counter and a drive gear rotatable in response to film movement for increasing the count in the counter by one for each frame of film advance, the drive gear being effective to change the count only after advance of the leader portion of the film. A cam which is incrementally rotated by an escapement mechanism in response to each frame of film advance moves a release lever to a first position for preventing counting during advancement of the leader portion of the film and thereafter to a second position for permitting counting.
