Claims
- 1. A reader-printer comprising:
- projection means for projecting an image of a microfilm to a screen and onto a photosensitive medium;
- copy forming means for forming the image projected onto the photosensitive medium into copies;
- feed means for feeding copy papers toward the photosensitive medium;
- an image rotation prism disposed in a light path of said projection means and having aberration between light axes incident thereto and emitted therefrom; and
- elimination means for eliminating a difference between a location of the projected image and a location of the fed paper so as to form the image coincidentally onto the copy paper irrespective of aberration of the light axes.
- 2. A reader-printer of claim 1, wherein said prism has a trapezoidal shape.
- 3. A reader-printer of claim 1, wherein said prism is disposed adjacent a projection lens.
- 4. A reader-printer with a reader mode and print mode comprising:
- projection means for projecting an image of a microfilm to a screen and onto a photosensitive medium;
- copy forming means for forming the image projected onto the photosensitive medium;
- feed means for feeding copy papers toward the photosensitive medium;
- an image rotation means disposed in a light path of said projection means for optically rotating the image;
- drive means for driving siad image rotation means;
- discrimination means for detecting whether or not the orientation of the projected image agrees with the orientation of the fed paper; and
- control means, in response to disagreement detected by said discrimination means, for controlling said drive means so as to be driven at the time of a mode change from the reader mode to the print mode.
- 5. A reader-printer of claim 4, wherein said discrimination means includes a detection means for detecting the orientation of the projected image.
- 6. A reader-printer of claim 4, wherein said control means controls the drive means so as to rotate the projected image through right angles.
