ABSTRACT:
FIELD OF THE INVENTION
The invention relates to photography and more particularly relates to a latched film unit, a latching device, a system, and a method.
BACKGROUND OF THE INVENTION
In film photography, film is exposed by a consumer and then, generally submitted to a photofinisher for processing. Communication between the consumer and photofinisher is limited and is usually in the form of instructions written on a photofinishing envelope. Instructions are sometimes written or taped or otherwise recorded on the film cassette. There are risks that instructions will be ambiguous, or unreadable, or misplaced, or will be erroneously erased or ignored.
It would thus be desirable to provide an improved film unit, devices, methods, and systems in which the state of one or more predetermined functions can be easily and unambiguously communicated.
SUMMARY OF THE INVENTION
The invention is defined by the claims. The invention, in its broader aspects, provides a latched film unit, latching device, system, and method. The latched film unit has a support, a filmstrip held by the support, and a latch mounted to the support. The latch is reversibly switchable between a first state and a second state and can enable or disable an access right of a memory element in the film unit. A latching device operates the film unit.
It is an advantageous effect of at least some of the embodiments of the invention that latched film units, latching devices, methods and systems are provided in which the state of one or more predetermined functions can be easily and unambiguously communicated.
