Abstract

PURPOSE:To permit the use of a large-sized eye cup without any trouble by making the eye cup movable between a normal position and a retreat position, and providing an interlocking mechanism which interlocks the movement of the eye cup and the opening and closing of the back cover. CONSTITUTION:An eye cup 3 is movable between a normal position located correctly at an eye piece and a retreat position as shown by 3' located on the outside of the moving range of a back cover 2 at the time of opening or closing the cover 2. An interlocking mechanism interlocking the movement of this eye cup 3 and the opening and closing of the cover 2 is provided. An eye cup slide lock pin 4 and a back cover opening and closing lock pin 5 are provided. The eye cup 3 moves in an arrow B direction and the cover 2 rotates in an arrow C direction. When a back cover opening and closing switch 5 is moved in the direction A, the lock pin of the cover 2 is released and the cover 2 moves in the direction C.
