ABSTRACT:
FIELD OF THE INVENTION
The invention relates to photography and more particularly relates to a film cassette having a memory module, photographic device, and method for registering the memory module.
BACKGROUND OF THE INVENTION
In order to better record ancillary information about captured images, some film cassettes have an internal electronic memory, which is written to by a microprocessor in a camera. Good electrical contact must be maintained in the camera between a series of fixed contacts on the memory and a series of leads in the camera. To reduce overall camera and film cassette size, the parts involved are quite small. Misalignment easily occurs unless all parts are precisely made.
It would thus be desirable to provide an improved film cassette having memory module, photographic device, and method in which the memory module can partially self-align.
SUMMARY OF THE INVENTION
The invention is defined by the claims. The invention, in its broader aspects, provides a photographic device that includes a film cassette that has a shell having a film space and a module slot external to the film space. The filmstrip coiled within said film space. A memory module is loosely retained in the module slot. The photographic device has a terminal block that orients and holds the memory module when the film cassette is loaded.
It is an advantageous effect of at least some of the embodiments of the invention that an improved film cassette having memory module, photographic device, and method in which the memory module can partially self-align.
