PROBLEM TO BE SOLVED: To prevent a pack chamber lid from being opened when an instant film is loaded. SOLUTION: A hook 27 to be locked is formed on the pack chamber lid 21 for opening/closing a pack chamber 25 and a locking hook 28 to be engaged with the hook 27 thereby locking the pack chamber lid 21 is formed on a lock lever built in the periphery of the pack chamber 25. A camera 2 counts by a film counter the number of discharged sheets of the loaded instant film. A count value of the film counter is referred to when an opening button 22 for opening the pack chamber lid 21 is manipulated. The pack chamber lid 21 is prevented from being opened when the instant film remains in the pack chamber 25. Without the instant film left, a motor for discharging the film is reversed to move the lock lever to a release position, thereby releasing the locking between the locking hook 28 and the hook 27 to be locked. |
