PURPOSE:To easily perform maintenance operating such as mirror cleaning by bringing a handle down, grasping the side of a mirror with an interlocking cam, then, bringing a pressing plate out of contact with a mirror presser foot. CONSTITUTION:This mirror 2 is housed in a mirror holder 1, an optical axis adjusting part (adjust screw) is provided, the mirror presser foot 3 is inserted. Compressive force is acted by a spring 7 to a freely rotative press plate 6 to give pressure to the mirror presser foot 3 and this pressure is released by rotation. The handle 4 is brought down and the side of the mirror 2 is grasped by an interlocking cam 10, then, the pressing plate 6 is brought out of contact with the presser foot 3 to the mirror. In this way, the attaching and detaching operations of the mirror, too, are easy and detaching operation of a screw can be disused. |
