ABSTRACT:
A camera comprising a shutter blade supported to move open to expose a frame on a filmstrip, a shutter actuator supported for movement to move the shutter blade open and for movement to be re-cocked, an actuating spring for urging the shutter actuator to move the shutter blade open, and a metering/re-cocking member having a metering pawl for engaging the filmstrip at a perforation during exposure of the frame, is characterized in that the metering/re-cocking member has a re-cocking portion and is supported for movement to move the re-cocking portion against the shutter actuator to move the shutter actuator to be re-cocked, a film tensioning spring urges the metering/re-cocking member, when the metering pawl engages the filmstrip at a perforation, to prevent the frame being exposed from shifting during exposure, and the shutter actuator is supported for movement to be spaced from the metering/re-cocking member, when the shutter actuator is re-cocked, to prevent the actuating spring from exerting any influence on the metering pawl when the frame is exposed.
