Abstract

PURPOSE: To make it possible to use various projection lenses differing in focal length including long focus lenses long in lens barrel by making it possible to adjust freely a relative interval between a reflex mirror and projection lens in accordance with the focal length of the projection lens.
CONSTITUTION: Ring-shaped support pedestal 16 is engaged with the outer circumference of holding cylinder 12 by fixing screws 17 and external groove 13 being rotatable. Reflex-mirror shore 21 is pivoted on axle 20 penetrating support part 18 provided at the side end of support pedestal 16 projecting and support part 18 is tightened up by turning knob 19 to fix shore 21. Shore 21 is fitted with reflex- mirror slider 26 and pinion 27 provided inside of it engages with rack 28 of shore 21 to permit slider 26 to slide freely on shore 21 through the rotation of knob 29, adjusting the interval between reflex-mirror holding plate 10 and projection lens 11a. Holding plate 10 is pivoted on slider 26 being rotatable and its angle is adjusted through the rotation of knob 23 provided on the same axle with clamp screw 25.
