Abstract
A reader-printer comprises a housing having a viewing opening, a screen disposed within the housing, means for moving the screen between an exposure position and a position spaced apart from the exposure position, means for projecting the image of a film onto the exposure position, means for feeding a copy sheet to the exposure position, means for delivering the copy sheet from the exposure position, and means for controlling external light entering the housing through the viewing opening.
Claims22
A reader-printer comprising:
- a housing having a viewing opening;
- screen means disposed within said housing for being viewed through said viewing opening;
- means for projecting a light image along a projection path to an exposure position within said housing;
- means for moving said screen means between a first viewing position in said projection path and a second position spaced apart from said projection path;
- and
- means for feeding a copy sheet to said exposure station for exposure to the projected light image, wherein said screen means shields the exposure position from external light entering through said viewing opening when the screen is at second position apart from said projection path.
A reader-printer comprising:
- a housing having a viewing opening;
- a movably mounted screen disposed within said housing for being viewed through said viewing opening;
- means for projecting a light image along a projection path to an exposure position;
- means for moving said screen between a first viewing position in said projection path, and a second position disposed outside said viewing path wherein said screen closes said viewing opening;
- and
- means for feeding a copy sheet to said exposure position for exposure to said projected light image when said screen is moved to said second position.
A recording device comprising:
- a housing having a viewing window;
- means for forwarding a photosensitive recording medium to a recording position, and from said recording position to a developing position in said housing;
- means for projecting an image onto said recording medium at said recording position, and for forming a latent image on said recording medium;
- developing means disposed at said developing position to render visible the latent image formed on said recording medium;
- and
- screen means having a light diffusing and reflecting surface, said screen means being mounted for movement between a viewing position adjacent said recording position, and a second position wherein said screen means intercepts light entering through said viewing window.
An apparatus for reproducing an image on a recording medium comprising:
- a casing having a viewing opening therein;
- means for moving said recording medium along a predetermined path past an exposure position in said casing;
- means for projecting an image to said exposure position disposed along said path;
- means disposed within said casing for forming a latent image on said medium using said projected image;
- developing means disposed within said casing along said predetermined path for carrying out development of the latent image formed on said recording medium;
- and
- a screen movable between a position at which the projected image is applied to the screen for viewing through said opening, and a position wherein said screen closes said viewing opening.
An image observing and reproducing device, operable in separate image observation and image reproduction modes, said device comprising:
- a housing having a viewing opening formed therein;
- an exposure surface disposed within said housing;
- lens means for focussing an image on said exposure surface;
- means for forming a light path extending from said lens means to said exposure surface;
- screen means movably mounted for being positioned at said exposure surface when the device is operated in said observation mode, wherein the image is thereby focussed on said screen means for viewing through said housing opening, and for being positioned outside said light path and at a location to intercept external light directed through said housing opening toward said exposure surface when the device is operated in said reproduction mode;
- and
- means for positioning a photosensitive body at said exposure surface at least during said reproduction mode.
