Abstract

PURPOSE:To simplify the construction, by changing the reflection factor or reflected area of a mirror in accordance with the magnification of an image. CONSTITUTION:Sliding tubes 14, 15 are respectively inserted to a pair of guide rods 12, 13, a supporting plate 16 is provided to the tubes, and an in-mirror lens 4 is fixed on the plate 16. A pair of sliding tubes 17, 18 are inserted to the guide rods 12, 13, the sliding tubes are fixed with a mirror supporting plate 19, which is fitted to a mirror 3. A spring is suspended between the plate 19 and the supporting plate 16 so that the lens 4 and the mirror 3 can be moved together. A belt 22 is belted on a pair of pulleys 23, 24 and driven with a motor 25, this motor 25 rotates in accordance with the designated magnification to move the in-mirror lens 4 and the mirror 3 to a specified position.
