Abstract
PURPOSE: To enable projection magnification to be changed without changing the moving speed of moving members such as image receiving surface by moving a reflection member which has an inclination 90°-θ to the optical axis of a projecting lens and a reflection member having an inclination of 2θ with respect to this.
CONSTITUTION: A reflection member m1 is provided by having an inclination of 90°-θ to the optical axis of a projecting lens 1, and a reflection member m2 is provided by having an inclination of 2θ with respect to the reflection member m1 in order to further reflect the light reflected by the reflection member m1. The image of the end part (f) of a microfilm 2 which is irradiated by a light source 3 and is placed still is reflected by the reflection members m1, m2 before the scanning by luminous flux 8 is started and this image is macro-projected in the position of a slit 6. In the state that the reflection members m1, m2 have finished moving in the arrow direction, the luminous flux 7 passing the end part (e) of the microfilm 2 is reflected by the reflection members m1, m2 and is macroprojected in the position of the slit 6. This is equal to that the full irradiation optical path moves by the length L of the macro-projected image by the movement of the reflection members m1, m2 and scans and exposes the entire irradiation angle.
