CONSTITUTION:A lens holder 38 is arranged in a recesd part 35, the flat spring part 42a of a pressure bar spring 42 is fitted in a groove 36, and the top part 42c of a pressing part 42b is presd against the projecting part 41 of the lens holder 38, thereby bringing the lens holder 38 into press-contact with the inner surface of the recesd part 35. In this condition, a fixed screw 43 is screwed into a screw hole 37 via the hole 44 of the pressure bar spring 42 and via the oblong hole 40 of the lens holder 38, and the lens holder 38 is fixed on a expander lens supporting part 32b. In this ca, the position of fixing the lens holder 38 is adjustable within the length of the oblong hole 40, and therefore the position of the cond beam expander lens 25 is adjustable in its depth direction within the length of the oblong hole 40.
