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.
Claims14
A photo printer for recording an image by projecting printing light onto a photosensitive recording material, said photo printer comprising:
- a printing head which projects said printing light onto said photosensitive recording material;
- a loading chamber for containing a plurality of said photosensitive recording materials;
- a lid member that is movable between an open position where said loading chamber is open and a closed position where said loading chamber is closed;
- developing means for carrying out development during ejecting said photosensitive recording material outside of said photo printer;
- counting means for counting remaining number that represents an amount of said photo-sensitive recording material left inside said loading chamber;
- a lid moving mechanism that is changeable between a lock state where said lid member is locked at said closed position, and a release state where said lid member is released and allowed to move to said open position;
- and
- control means for checking said remaining number and prohibiting said lid moving mechanism from changing into said release state when said remaining number is equal to or more than one.
A photo printer for recording an image by projecting printing light onto a photosensitive recording material, said photo printer comprising:
- a printing head which projects said printing light onto said photosensitive recording material;
- a loading chamber for containing a plurality of said photosensitive recording materials;
- a lid member that is movable between an open position where said loading chamber is open and a closed position where said loading chamber is closed;
- developing means for carrying out development during ejecting said photosensitive recording material outside of said photo printer;
- a feeding motor for actuating said developing means;
- a lid moving mechanism that is driven by said feeding motor and changeable between a lock state where said lid member is locked at said closed position, and a release state where said lid member is released and allowed to move to said open position;
- and
- a lock release means for releasing said lid member, wherein a message is generated when said lock release means is actuated while said loading chamber contains at least one of said photosensitive recording materials, said message indicating the presence of said at least one of said photosensitive recording materials.
A photo printer for recording an image by projecting printing light onto a photosensitive recording material, said photo printer comprising:
- a printing head which projects said printing light onto said photosensitive recording material;
- a loading chamber for containing a plurality of said photosensitive recording materials;
- a lid member that is movable between an open position where said loading chamber is open and a closed position where said loading chamber is closed;
- developing means for carrying out development during ejecting said photosensitive recording material outside of said photo printer;
- a feeding motor for actuating said developing means;
- a lid moving mechanism that is changeable between a lock state where said lid member is locked at said closed position, and a release state where said lid member is released and allowed to move to said open position;
- an operation member that is operated externally for opening said lid member;
- and
- control means that changes said lid moving mechanism into said release state when said operation member is operated over a predetermined time continuously.
