Claim 3

The module according to claim 1, wherein said light means is located a predetermined distance from said sound negative.

Claim 4

The module according to claim 1, wherein said light means is a fiber optic light source.

Claim 5

The module according to claim 3, further including at-least one fiber optic cable extending from said fiber optic light source, wherein said cable includes an output aperture having a rectangular configuration.

Claim 6

The module according to claim 4, wherein said output aperture is approximately 0.062 wide and 0.177 inches long.

Claim 7

The module according to claim 4, further including a filter box affixed between said fiber optic light source and said output aperture for filtering light generated by said fiber optic light source to provide light suitable for exposing said film.

Claim 8

The module according to claim 1, further including locking means for inhibiting rotation of said pivot arm to maintain said main roller substantially between said first and second guide rollers.

Claim 9

The module according to claim 7, wherein said locking means includes a spring loaded pin extending downward from said from pivot arm, said pin moveable between an extended position wherein said pin extends out of said pivot arm and a retracted position wherein said pin retracts within said pivot arm and is biased to move to said extended position, said locking means further including a roller member rotatably affixed to said baseplate adjacent said first guide roller wherein when said pivot arm rotates relative to said baseplate, said pin contacts said roller element and retracts within said pivot arm, and when said pivot arm continues to rotate past said roller element said pin moves to said extended position, thereby contacting a side of said roller element and inhibiting rotation of said pivot arm.

Claim 10

The module according to claim 1, wherein said first and second guide rollers each include end flanges to prevent side to side misregistration of said sound master and said film.

Claim 11

A module for a contact printer used to manufacture a motion picture, wherein a sound negative having a negative digital soundtrack is placed in contact with motion picture film, comprising: a baseplate affixed to said contact printer; a first guide roller rotatably mounted to said baseplate, wherein said first guide roller includes a first rotation axis and said sound negative contacts a left side of said first guide roller; a second guide roller rotatably mounted to said baseplate, wherein said second guide roller includes a second rotation axis and said sound negative contacts a left side of said second guide roller, said first and second guide rollers further including end flanges to prevent side to side misregistration of said sound master and said film; a pivot arm rotatably mounted to said baseplate, said pivot arm including a spring loaded pin extending downward from said pivot arm, said pin moveable between an extended position wherein said pin extends out of said pivot arm and a retracted position wherein said pin retracts within said pivot arm and is biased to move to said extended position; a main roller positioned between said first and second guide rollers and rotatably mounted to said pivot arm, wherein said main roller includes a third rotation axis and said film contacts a right side of said main roller, and said first, second and third rotation axes are coplanar whereby said sound negative and said film are configured in a substantially S-shaped path between said first guide roller and said main roller and in a substantially reverse S-shaped path between said main roller and said second guide roller; a roller member rotatably affixed to said baseplate adjacent said first guide roller wherein when said pivot arm rotates relative to said baseplate, said pin contacts said roller clement and retracts within said pivot arm, and when said pivot arm continues to rotate past said roller element said pin moves to said extended position, thereby contacting a side of said roller element and inhibiting rotation of said pivot arm; at least one fiber optic cable having an output end positioned adjacent said sound negative and opposite said main roller, said cable connected to a fiber optic light source, wherein light generated by said light source is transmitted by said cable and emitted from said output end wherein said light impinges on said sound negative thereby forming a positive digital optical soundtrack on said film.

Claim 12

A module for a contact printer used to manufacture a motion picture, wherein a sound negative having a negative digital soundtrack is placed in contact with motion picture film, comprising: a baseplate affixed to said contact printer; a first guide roller rotatably mounted to said baseplate, wherein said first guide roller includes a first rotation axis and said sound negative contacts a left side of said first guide roller; a second guide roller rotatably mounted to said baseplate, wherein said second guide roller includes a second rotation axis and said sound negative contacts a left side of said second guide roller, said first and second guide rollers further including end flanges to prevent side to side misregistration of said sound master and said film; a pivot arm rotatably mounted to said baseplate, said pivot arm including a spring loaded pin extending downward from said pivot arm, said pin moveable between an extended position wherein said pin extends out of said pivot arm and a retracted position wherein said pin retracts within said pivot arm and is biased to move to said extended position; a main roller positioned between said first and second guide rollers and rotatably mounted to said pivot arm, wherein said main roller includes a third rotation axis and said film contacts a right side of said main roller, and said first, second and third rotation axes are coplanar whereby said sound negative and said film are configured in a substantially S-shaped path between said first guide roller and said main roller and in a substantially reverse S-shaped path between said main roller and said second guide roller; a roller member rotatably affixed to said baseplate adjacent said first guide roller wherein when said pivot arm rotates relative to said baseplate, said pin contacts said roller clement and retracts within said pivot arm, and when said pivot arm continues to rotate past said roller element said pin moves to said extended position, thereby contacting a side of said roller element and inhibiting rotation of said pivot arm; at least one fiber optic cable having an output end positioned adjacent said sound negative and opposite said main roller, said cable connected to a fiber optic light source, wherein light generated by said light source is transmitted by said cable and emitted from said output end wherein said light impinges on said sound negative thereby forming a positive digital optical soundtrack on said film.

Claim 13

The module according to claim 10, wherein said cable further includes an opaque bushing secured to said output end, said bushing having a rectangular aperture for emitting said light.

Claim 14

The module according to claim 11, wherein said rectangular aperture is approximately 0.062 inches wide and 0.177 inches long.

Claim 15

The module according to claim 12 wherein said rectangular aperture is positioned a predetermined distance from said sound negative.

Claim 16

The module according to claim 13, further including a filter box affixed to said cable between said light source and said output end for filtering light generated by said light source to provide light suitable in color balance for exposing said film.

Claim 17
