Data recording camera

Claim 2

In a camera comprising a film exposure system which includes an object lens system for focussing of image-wise light onto photosensitive film material provided in said camera and shutter means selectively movable to positions to permit or to prevent passage of said image-wise light onto said film material, a viewfinder system which is provided independently of said film exposure system and includes an eyelens permitting viewing of an object from which image-wise light may be directed by said object lens system onto said film material, and camera wall portions defining a film exposure system compartment and a viewfinder system compartment, the improvement comprising: externally adjustable data specification means to selectively present different items of data, first optical means for directing said image-wise light carrying said data content to said eyelens, whereby said data content is viewable in said viewfinder system, second optical means for directing said image-wise light carrying said data content onto a portion of said film material, whereby said data content may be recorded on said film material, and gate means operatively coupled to said shutter system and movable to closed position and open position, said gate means being closed to prevent passage by said second optical means of said image-wise light onto said film material when said shutter means is closed, and being opened to permit passage of image-wise light onto said film material by said second optical means when said shutter means is opened, whereby content of said data specification means may be selectively recorded on said film material.

Claim 3

In a camera comprising a film exposure system which includes an object lens system for focussing of image-wise light onto photosensitive film material provided in said camera and shutter means selectively movable to positions to permit or to prevent passage of said image-wise light onto said film material, a viewfinder system which is provided independently of said film exposure system and includes an eyelens permitting viewing of an object from which image-wise light may be directed by said object lens system onto said film material, and camera wall portions defining a film exposure system compartment and a viewfinder system compartment, and partition means separating said compartment, the improvement comprising: externally adjustable data specification means to selectively present different items of data, externally actuable normally unactuated illumination means to illuminate said data specification means, frame means defining openings permitting passage of image-wise light carrying content of said data specification means upon illumination of said data specification means by said illumination means and restricing passage of other light emitted by said illumination means, first optical means for directing said image-wise light carrying said data content to said eyelens, whereby said data content is viewable in said viewfinder system, second optical means for directing said image-wise light carrying said data content onto a portion of said film material, whereby said data content may be recorded on said film material, and gate means movably mounted in said partition means and operatively coupled to said shutter system for movement to closed and open positions, said gate means being closed and preventing passage by said second optical means of said image-wise light onto said film material when said shutter means is closed, and being opened and permitting passage of image-wise light by said second optical means when said shutter means is opened, whereby content of said data specification means may be selectively recorded on said film material.

Claim 4

In a camera comprising a film exposure system which includes an object lens system for focussing of image-wise light onto photosensitive film material provided in said camera and shutter means selectively movable to positions to permit or to prevent passage of said image-wise light onto said film material, a viewfinder system which is provided independently of said film exposure system and includes an eyelens permitting viewing of an object from which image-wise light may be directed by said object lens system onto said film material, and camera wall portions defining a film exposure system compartment and a viewfinder system compartment, and partition means separating said compartment, the improvement comprising: externally adjustable data specification means to selectively present different items of data, externally actuable normally unactuated illumination means to illuminate said data specification means, frame means defining openings permitting passage of image-wise light carrying content of said data specification means upon illumination of said data specification means by said illumination means and restricing passage of other light emitted by said illumination means, first optical means for directing said image-wise light carrying said data content to said eyelens, whereby said data content is viewable in said viewfinder system, second optical means for directing said image-wise light carrying said data content onto a portion of said film material, whereby said data content may be recorded on said film material, and gate means movably mounted in said partition means and operatively coupled to said shutter system for movement to closed and open positions, said gate means being closed and preventing passage by said second optical means of said image-wise light onto said film material when said shutter means is closed, and being opened and permitting passage of image-wise light by said second optical means when said shutter means is opened, whereby content of said data specification means may be selectively recorded on said film material.

Claim 5

Data recording camera as recited in claim 2, wherein said first optical means comprises a first full-reflection mirror positioned to receive image-wise light carrying content of said data specification means, and a first half-reflection mirror which is positioned on the optical axis of said viewfinder system and is disposed to receive image-wise light reflected by said first full-reflection mirror and to direct said image-wise light to said eyelens, and wherein said second optical means includes a second half-reflection mirror positioned between said data specification means and said first full-reflection mirror and a second full-reflection mirror which is disposed to receive imagewise light reflected by said second half-reflection mirror and direct said image-wise light onto said film material.
