Abstract
A camera comprising a film frame counter rotatable to successive numbered settings, and a counter actuator movable in engagement with the frame counter to rotate the frame counter to its next numbered setting, is characterized in that a bearing support for the frame counter supports the frame counter, first to permit the frame counter to be axially shifted to become separated from the counter actuator, and then to permit the frame counter to be rotated freely to reset the frame counter to an initial setting.
