Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
176 words
A camera comprising: a housing; means defining a chamber for receiving a film cassette containing at least one film unit; means for performing a function associated with the processing of the film unit; electrically energizable means adapted to be operatively coupled to said performing means; an electrical circuit connected to said electrically energizable means, said circuit including a pair of contacts adapted for engagement with the terminals of a battery located within said camera to provide a source of energy for said electrically energizable means; and means for defining a recess in an exterior surface of said housing for releasably receiving at least a portion of a battery assembly to couple the battery assembly to said housing, said recess including means for guiding a pair of battery terminals on the battery assembly to a position within said housing whereat the battery terminals on the battery assembly engage and move said contacts out of engagement with the terminals of the battery located within the camera thereby providing a new source of energy for said electrically energizable means.
Claim 2
Dependent Claim
176 words
A camera comprising: a housing; means defining a chamber for receiving a film cassette containing at least one film unit; means for performing a function associated with the processing of the film unit; electrically energizable means adapted to be operatively coupled to said performing means; an electrical circuit connected to said electrically energizable means, said circuit including a pair of contacts adapted for engagement with the terminals of a battery located within said camera to provide a source of energy for said electrically energizable means; and means for defining a recess in an exterior surface of said housing for releasably receiving at least a portion of a battery assembly to couple the battery assembly to said housing, said recess including means for guiding a pair of battery terminals on the battery assembly to a position within said housing whereat the battery terminals on the battery assembly engage and move said contacts out of engagement with the terminals of the battery located within the camera thereby providing a new source of energy for said electrically energizable means.
Claim 3
Dependent Claim
51 words
A camera as defined in claim 1 wherein said recess is located in a plane generally parallel with said exterior surface and includes an open end and a closed end, said open end having a greater width than said closed end to facilitate attachment of the battery assembly to said camera.
Claim 4
Dependent Claim
42 words
A camera as defined in claim 2 wherein said recess includes a rear wall and opposing side walls each said opposing wall including a portion tapering toward the other portion as said side walls terminate at said external surface of said housing.
Claim 5
Dependent Claim
172 words
A camera comprising: a housing; means defining a chamber for receiving a film cassette containing at least one film unit; means for performing a function associated with the processing of the film unit; electrically energizable means adapted to be operatively coupled to said performing means; an electrical circuit connected to said electrically energizable means, said circuit including a pair of contacts adapted for engagement with the terminals of a battery located within said camera to provide a source of energy for said electrically energizable means; and means in an exterior surface of said housing for receiving at least a portion of a battery assembly to couple the battery assembly to said housing, said receiving means including means for guiding a pair of battery terminals on the battery assembly to a position within said housing whereat the battery terminals on the battery assembly engage and move said contacts out of engagement with the terminals of the battery located within the camera thereby providing a new source of energy for said electrically energizable means.
Claim 6
Dependent Claim
172 words
A camera comprising: a housing; means defining a chamber for receiving a film cassette containing at least one film unit; means for performing a function associated with the processing of the film unit; electrically energizable means adapted to be operatively coupled to said performing means; an electrical circuit connected to said electrically energizable means, said circuit including a pair of contacts adapted for engagement with the terminals of a battery located within said camera to provide a source of energy for said electrically energizable means; and means in an exterior surface of said housing for receiving at least a portion of a battery assembly to couple the battery assembly to said housing, said receiving means including means for guiding a pair of battery terminals on the battery assembly to a position within said housing whereat the battery terminals on the battery assembly engage and move said contacts out of engagement with the terminals of the battery located within the camera thereby providing a new source of energy for said electrically energizable means.
