Abstract
A lock claw is provided on a pack loading door for opening a pack loading chamber. A lock lever is attached to the pack loading chamber. The lock lever is movable between a lock position where a lock claw engages with the lock claw, and a release position where a lock claw is away from the lock claw. The camera has a system controller and a film counter. The film counter counts a remaining number that represents the number of the instant film left inside the pack loading chamber. When a lock release button is operated, the system controller checks the remaining number. If the remaining number is equal to zero, the system controller controls a feeding motor to rotate inversely, so that the lock lever moves to the release position. If the remaining number is more than zero, the system controller keeps the lock lever at the lock position.
