Abstract
Abstract A device for use in a camera in conjunction with exposure of a photographic film carried by carrier structure including a frame bounding a light passing zone, includes (a) a template in the form of a locally transparent, generally planar and rectangular sheet adapted to carry an image to be reproduced on the film, (b) there being multiple elongated ribs integral with the sheet, and projecting outwardly from the plane of the sheet, (c) the multiple ribs substantially bounding all of the light passing zone to block light access to that zone in directions parallel to the plane of the sheet, (d) the ribs including a first laterally elongated rib at one end of the template to engage the frame adjacent one end of the template to prevent removal of the template in response to endwise removal of exposed film from the carrier structure, whereby the template sheet remains in the path of light transmission in directions generally normal to the plane of the sheet and to unexposed film carried by the carrier structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
176 words
A device for use in a camera in conjunction with exposure of a photographic film carried by carrier structure including a frame bounding a light passing zone, and comprising (a) a template in the form of a locally transparent, generally planar and rectangular sheet adapted to carry an image to be reproduced on the film, (b) there being multiple elongated ribs integral with said sheet, and projecting outwardly from the plane of the sheet, (c) said multiple ribs substantially bounding all of said light passing zone to block light access to said zone in directions parallel to the plane of the sheet, (d) said ribs including a first laterally elongated rib at one end of the template to engage the frame adjacent said one end of the template to prevent removal of the template in response to endwise removal of exposed film from the carrier structure, whereby the template sheet remains in the path of light transmission in directions generally normal to the plane of the sheet and to unexposed film carried by the carrier structure.
Claim 2
Independent Claim
176 words
A device for use in a camera in conjunction with exposure of a photographic film carried by carrier structure including a frame bounding a light passing zone, and comprising (a) a template in the form of a locally transparent, generally planar and rectangular sheet adapted to carry an image to be reproduced on the film, (b) there being multiple elongated ribs integral with said sheet, and projecting outwardly from the plane of the sheet, (c) said multiple ribs substantially bounding all of said light passing zone to block light access to said zone in directions parallel to the plane of the sheet, (d) said ribs including a first laterally elongated rib at one end of the template to engage the frame adjacent said one end of the template to prevent removal of the template in response to endwise removal of exposed film from the carrier structure, whereby the template sheet remains in the path of light transmission in directions generally normal to the plane of the sheet and to unexposed film carried by the carrier structure.
Claim 3
Dependent Claim
58 words
The device of claim 1 where said ribs include a second laterally elongated rib at the opposite end of the template and extending parallel to said one rib, and third and fourth longitudinally elongated ribs respectively at opposite side edges of the sheet, all of the ribs projecting substantially equally outwardly relative to the plane of the sheet.
Claim 4
Dependent Claim
37 words
The device of claim 2 wherein the third rib terminates at a location spaced from one end of the second rib to provide a gap therebetween for accommodating movement of a film-retracting finger carried by the camera.
Claim 5
Dependent Claim
18 words
The device of claim 2 wherein the fourth rib extends between ends of the first and second ribs.
Claim 6
Dependent Claim
26 words
The device of claim 1 wherein that portion of the template between at least one rib and a locally transparent zone of the template is opaque.
Claim 7
Dependent Claim
31 words
The device of claim 1 wherein said ribs are bonded to said template sheet, and are resiliently flexible to flex with the template sheet upon its assembly to the carrier frame.
Claim 8
Dependent Claim
27 words
The device of claim 6 wherein said ribs consist of plastic material, and are sufficiently thin to allow flexing of the sheet producing bowing of the ribs.
Claim 9
Dependent Claim
37 words
The device of claim 1 and including the frame carrying stacked film directly beneath the light passing zone of the template sheet, the film adapted to be extracted parallel to the template for ejection from the camera.
Claim 10
Dependent Claim
27 words
The device of claim 1 wherein the rectangular template has the following approximate overall dimensions: lateral width - 3 5/16 inches longitudinal length - 3 11/16 inches
Claim 11
Dependent Claim
27 words
The device of claim 5 wherein the light passing zone is generally circular and transparent, the remainder of the template extending proximate all the ribs being opaque.
Claim 12
Dependent Claim
22 words
The device of claim 2 wherein each rib is spaced from, but extends parallel to the template edge closest to that rib.
Claim 13
Dependent Claim
44 words
The device of claim 11 wherein the template has edge portions between said ribs and the template edges, said edge portions being resiliently flexible to be deflected upon engagement with the carrier frame when the template and ribs are fitted to the carrier frame.
