PROBLEM TO BE SOLVED: To prevent dust or external light from entering a pentagonal mirror part by providing a dust-proof cover with which the pentagonal mirror is covered and which can follow up the movement of a movable armor and the pentagonal mirror between a camera body and the movable armor. SOLUTION: The pentagonal mirror 11 is covered with the dust-proof cover 23 existing between the movable armor 13 and the mirror 11. The cover 23 is attached to the upper end of a mirror box other than the area of the ocular 39 of the camera main body 29, and is attached to the outer periphery of the ocular 39 in the area of the ocular 39. The material of the cover 23 is a rubber curtain having flexibility, dustproof and lightproof property. When a driving arm 53 is rotated clockwise centering a shaft 55, the mirror 11 is rotated counterclockwise centering a rocking supporting shaft 49. The mirror 11 goes down while the lower end of a part having a 3rd reflection surface 17 presses down a focusing screen block 21. The armor 13 is moved downward as the mirror 11 goes down, and the cover 23 is bent while following up the movement of the armor 13.
