The camera is provided with a reflector system comprising reflectors, lenses and shutters for use in projecting two images onto a light sensitive recording medium in side-by-side relationship to produce a stereograph print, Means, such as obturators, are provided for rendering the reflector system inoperative when the camera is used for projecting a single image through a lens and shutter onto the light sensitive recording medium to produce a mono photograph. ## Claims ### Claim 1 A camera for producing stereoscopic and mono photo graphic images, the camera comprising: a camera casing having a chamber formed therein; a reflector system for projecting two images onto a light sensitive recording medium in side-by-side relationship to produce a stereograph, said reflector system being moveably mounted within the chamber of the camera casing for movement between an operative and an inoperative condition, said reflector system including means for reflecting the two images toward the light sensitive recording medium and a partition positioned relative to the reflecting means to separate the two image projected onto the light sensitive recording medium; means for projecting a single image onto the light sensitive recording medium to produce a mono photograph at times when the reflector system is in the inoperative condition; and means for moving the reflector system within the camera casing between the operative and inoperative condition. ### Claim 2 (depends on 1) The camera of claim 1, wherein said reflecting means of the reflector system includes first and second reflectors and a first lens for projecting the first image, and third and fourth reflectors and a second lens for projecting the second image, and the projecting means includes a third lens for projecting said single image. ### Claim 3 A camera for producing stereoscopic and mono photographic images, the camera comprising: a camera casing having a chamber formed therein; a reflector system for projecting two images onto a light sensitive recording medium in side-by-side relationship to produce a stereograph, said reflector system having an operative and an inoperative condition, said reflector system being slidably mounted within the chamber of the casing for movement between the operative and inoperative condition; means for projecting a single image onto the light sensitive recording medium to produce a mono photograph at times when the reflector system is in the inoperative condition; and means for moving the reflector system within the camera casing between the operative and inoperative condition. ### Claim 4 A camera for producing stereoscopic and mono photographic images, the camera comprising: a reflector system for projecting two images onto a light sensitive recording medium in side-by-side relationship to produce a stereograph, said reflector system having an operative and an inoperative condition, said reflector system including first and second reflectors and a first lens for projecting the first image, and third and fourth reflectors and a second lens for projecting the second image, the reflector system further comprising a first obturator disposed between the first and second reflector and a second obturator disposed between the third and fourth reflector, said first and second obturators having an open position for allowing light to pass between the first and second reflectors and third and fourth reflectors, respectively, at times when the reflector system is in the operative condition; and means for projecting a single image onto the light sensitive recording medium to produce a mono photograph at times when the reflector system is in the inoperative condition, said projecting means including a third lens for projecting the single image; and means for moving the reflector system between the operative and inoperative condition. ### Claim 5 (depends on 4) The camera of claim 4, wherein the projecting means includes an obturator moveably disposed to allow light to pass through the third lens at times when the reflector system is in the inoperative condition. ### Claim 6 (depends on 5) The camera of claim 5, further comprising a partition having an operative and inoperative condition, said partition being disposed adjacent the light sensitive recording medium in the operative position at times when the reflector system is in the operative mode to prevent the two images from overlapping and to produce a dividing line therebetween. ### Claim 7 (depends on 4) The camera of claim 4, further comprising a film holding section wherein the light sensitive recording medium is disposed, said film holding section projecting outwardly from the reflector system to prevent stray rays of light from being reflected by the reflector system onto the light sensitive recording medium. ### Claim 8 (depends on 7) The camera of claim 7, wherein the film holding section is detachable. ### Claim 9 A camera for producing stereoscopic and mono photographic images, the camera comprising: a camera casing having a chamber formed therein; a reflector system housed within the chamber of the camera casing for projecting two images onto a light sensitive recording medium in side-by-side relationship to produce a stereograph, said reflector system having an operative and an inoperative condition, said reflector system being adjustable within the chamber of the camera casing between the operative and inoperative condition; means for projecting a single image onto the light sensitive recording medium to produce a mono photograph at times when the reflector system is in the inoperative condition; and means for adjusting the reflector system within the camera casing between the operative and inoperative condition. ### Claim 10 (depends on 3) The camera of claim 3, wherein the camera includes a single lens, the reflector system being in alignment with the single lens in the operative condition and being displaced out of alignment with the single lens when in the inoperative condition.
