Camera with back-up shutter and provisions for recording data in conjunction with a primary image

Claim 2

In a single lens reflex camera having a body, a main lens mounted on said body, means for positioning a film in a film plane within said body to be exposed through said main lens so that a primary image is formed on said film an exposure-timing shutter disposed in front of said film plane, and at least one back-up shutter panel movable about a pivot axis beteen a closed position covering said film plane and an open postion exposing said film plane, the improvement comprising: data image recording means mounted within said body between said lens and said film plane for providing an illuminated data image to be recorded on said film in conjunction with said primary image, a light-blocking frame extending around an area of said film plane on which said data image is to be recorded, said shutter panel defining a cutaway area shaped and dimensioned to permit at least a portion of said data image recording means to pass therethrough as said shutter panel moves between said open and closed positions, said shutter panel also having an edge portion extending along said cutaway area and arrange to engage said frame in a light-tight manner when said shutter panel is in said closed position.

Claim 3

The camera of claim 1 wherein said data recording means comprises display means for generating a variable data image in response to an electrical input signal.

Claim 4

The camera of claim 2 wherein said data recording means further comprises projection means for projecting said data image onto said film.

Claim 5

The camera of claim 3 wherein said projection means includes a prism at least partially surrounded by said frame.

Claim 6

The camera of claim 4 wherein said display means and said projection means are arranged so that said data image follows a light path from said display means to said projection means that extends under said shutter panel when said shutter panel is in said open position.

Claim 7

The camera of claim 4 wherein said projection means comprises a prism having two parallel reflection surfaces therein.

Claim 8

The camera of claim 1 wherein said data recording means includes a prism with two parallel reflections therein.

Claim 9

The camera of claim 7 wherein said data recording means further comprises a lens disposed between said prism and said film plane.

Claim 10

The camera of claim 1 wherein said data recording means extends toward said film to said pivot axis and said frame is aligned with said pivot axis.

Claim 11

The camera of claim 1 wherein said portion of said data recording means that passes through said shutter panel includes a lens.

Claim 12

In a single lens reflex camera having a body, a main lens mounted on said body, means for positioning a film to be exposed through said main lens in a film plane within said body so that a primary image can be formed on said film, an exposure-timing shutter disposed in front of said film plane, and first and second back-up shutter panels each movable about a pivot axis between a closed position covering said film plane and an open position peripendicular to said film plane, the improvement comprising: display means disposed within said body between said main lens and said film plane for generating an illuminated variable data image in response to an externally originated electrical input signal; and projection means for projecting said data image onto said film arranged so that said image follows a light path extending from said display means under said first shutter panel to said projection means when said first shutter panel is in said open position, said projection means comprising a prism adjacent said film plane having two parallel reflection surfaces therein, a lens between said prism and said film plane, and a frame extending around said prism adjacent to said film plane; said first shutter panel having an edge portion defining a cutaway area shaped and dimensioned to permit at least a portion of said prism to pass there through as said first shutter panel moves between said open and closed positions, said edge portion being arranged to engage said frame in a light-tight manner when said first shutter panel is in said closed position.

Claim 13

In a single lens reflex camera having a body, a main lens mounted on said body, means for positioning a film to be exposed through said main lens in a film plane within said body so that a primary image can be formed on said film, an exposure-timing shutter disposed in front of said film plane, and first and second back-up shutter panels each movable about a pivot axis between a closed position covering said film plane and an open position peripendicular to said film plane, the improvement comprising: display means disposed within said body between said main lens and said film plane for generating an illuminated variable data image in response to an externally originated electrical input signal; and projection means for projecting said data image onto said film arranged so that said image follows a light path extending from said display means under said first shutter panel to said projection means when said first shutter panel is in said open position, said projection means comprising a prism adjacent said film plane having two parallel reflection surfaces therein, a lens between said prism and said film plane, and a frame extending around said prism adjacent to said film plane; said first shutter panel having an edge portion defining a cutaway area shaped and dimensioned to permit at least a portion of said prism to pass there through as said first shutter panel moves between said open and closed positions, said edge portion being arranged to engage said frame in a light-tight manner when said first shutter panel is in said closed position.

Claim 14

In a single lens reflex camera having a body, a main lens mounted on said body, means for positioning a film in a film plane within said body to be exposed through said main lens so that a primary image is formed on said film, an exposure-timing shutter disposed in front of said film plane, and at least one back-up shutter panel movable about a pivot axis between a closed position covering said film plane and an open position exposing said film plane, the improvement comprising: secondary image projection means mounted within said body for presenting an illuminated secondary image to be recorded on said film in conjunction with said primary image, a light-blocking frame extending around an area of said film plane on which said data image is to be recorded, said shutter panel defining a cutaway area shaped and dimensioned to permit at least a portion of said secondary image projection means to pass therethrough as said shutter panel moves between said open and closed positions, said shutter panel also having an edge portion extending along said cutaway area and arranged to engage said frame in a light-tight manner when said shutter panel is in said closed position.

Claim 15

In a single lens reflex camera having a body, a main lens mounted on said body, means for positioning a film in a film plane within said body to be exposed through said main lens so that a primary image is formed on said film, an exposure-timing shutter disposed in front of said film plane, and at least one back-up shutter panel movable about a pivot axis between a closed position covering said film plane and an open position exposing said film plane, the improvement comprising: secondary image projection means mounted within said body for presenting an illuminated secondary image to be recorded on said film in conjunction with said primary image, a light-blocking frame extending around an area of said film plane on which said data image is to be recorded, said shutter panel defining a cutaway area shaped and dimensioned to permit at least a portion of said secondary image projection means to pass therethrough as said shutter panel moves between said open and closed positions, said shutter panel also having an edge portion extending along said cutaway area and arranged to engage said frame in a light-tight manner when said shutter panel is in said closed position.
