Claim 9
Dependent Claim 113 words
A camera comprising a cassette-receiving chamber for holding a film cassette provided with a light lock which is pivoted closed before removing the cassette from said chamber, is characterized in that: said camera has an exterior opening to said chamber which is positioned to longitudinally admit an implement into the chamber for rotation to pivot the light lock closed and to further admit the implement into the chamber to push the cassette out of the chamber and which includes an internal edge configured for preventing the implement from being rotated to pivot the light lock open as the implement is further admitted into said chamber to push the cassette out of the chamber.
Claim 10
Independent Claim 86 words
A method of closing a pivotal light lock of a film cassette in a cassette-receiving chamber of a camera, and removing the cassette from the chamber, comprising: inserting a separate implement, not part of the camera, part way into the chamber through an ingress opening to end of the chamber; rotating the implement to pivot the light lock closed; and inserting the implement further into the chamber to push the cassette out of the chamber through an egress opening at an opposite end of the chamber.
Claim 11
Independent Claim 86 words
A method of closing a pivotal light lock of a film cassette in a cassette-receiving chamber of a camera, and removing the cassette from the chamber, comprising: inserting a separate implement, not part of the camera, part way into the chamber through an ingress opening to end of the chamber; rotating the implement to pivot the light lock closed; and inserting the implement further into the chamber to push the cassette out of the chamber through an egress opening at an opposite end of the chamber.
Claim 12
Dependent Claim 37 words
A method as recited in claim 7, wherein the implement is prevented from being rotated to pivot the light lock open as it is inserted further into the chamber to push the cassette out of the chamber.
Claim 13
Dependent Claim 38 words
A method as recited in claim 7, wherein the implement is inserted further into the chamber to push the cassette against a lid closing the chamber at said egress opening to push the lid to open the chamber.
Claim 14
Dependent Claim 39 words
A method as recited in claim 9, wherein the implement is rotated to pivot a latch which secures the lid closing the chamber to release the lid to permit the cassette to push the lid to open the chamber.
Claim 15
Dependent Claim 131 words
A camera comprising a cassette-receiving chamber for holding a film cassette provided with a light lock which is pivoted closed before removing the cassette from said chamber, is characterized in that: said camera has an exterior opening to said chamber positioned to longitudinally admit an implement into the chamber for rotation to pivot the light lock closed and to further admit the implement into the chamber to push the cassette out of the chamber; a lid which closes said chamber is supported for the cassette to push said lid to open the chamber when the cassette is pushed out of the chamber; and a latch secures said lid closing said chamber and is engageable with the light lock for movement to release the lid when the light lock is pivoted closed.
