Abstract
An image exposure apparatus switchable between a reader state for projecting an image on a screen for observation and a scan state for scanning exposure of the image, which includes plural scanning mirrors which integrally move on a same line to effect the image scanning. The mutual distance of the plural scanning mirrors is varied at the switching between the reader state and the scan state.
Claims21
An image exposure apparatus switchable between a reader state in which an image is projected on a screen for observation and a scan state in which said image is subjected to scanning exposure, comprising:
- plural scanning mirrors for effecting image scanning by movement on a same line;
- and
- variation means for varying the mutual distance of said plural scanning mirrors at the switching between said reader state and said scan state.
A reader-printer comprising:
- first optical means for forming a reader optical path for projecting an image of a film onto a screen;
- a second optical means for forming a printer optical path for projecting the image of the film onto an exposure portion,
- wherein said second optical means includes plural scanning mirrors capable of reciprocating motion in a same direction to effect scanning exposure of the image of the film on the exposure portion;
- and
- variation means for varying the mutual distance of said plural scanning mirrors in a reader mode and in a printer mode.
