ABSTRACT:
A camera includes a frame having a movably attached film engaging member including a metering pawl for engaging a contained filmstrip. A light locking cover attached to the frame prevents ambient light from entering a defined light tight enclosure surrounding the film engaging member with the exception of an opening to allow a locking portion of a second movable lever within the lighttight enclosure for engaging the film engaging member. The lever includes an integral light locking portion adjacent the locking portion which blocks the opening of the first light locking cover but allows the locking portion to engage the film engaging member. The access opening of the light locking cover is sufficiently large to allow pivoting movement of the locking portion, the cover preferably including a recess to allow the light blocking portion of the lever to effectively cover the opening in a lighttight manner.
