PURPOSE:To prevent one-sided out-of-focus of a finder image by adjusting at least one of the pivotally supporting parts on both sides of the pivotally supporting end of a mirror supporting member independently forward and backward in the arc and radial directions centering at the pivotal position of a mirror. CONSTITUTION:A shaft 13 is stuck to a mirror box by the pivotally supporting shaft on the left side of a mirror supporting member 2. A mirror 1 is fitted pivotally to a member 2 of a shaft 14. When a lever 17 is pressed by an adjusting screw 21, the lever 17 moves the shaft 13 along roughly the approximate arc centering at the shaft 14 against a spring 26. The lever 24 in this time is fixed by energizing of a spring 27. Therefore the finder image can be adjusted independently of the forward and backward out-of-focus. When a lever 24 is pressed by a screw 25, the lever 24 turns against a spring 27 and moves the shaft 13 along the radial direction of the approximate arc directing toward the shaft 14. Thus the one-sided out-of-focus of the finder image, operation defects, etc. are prevented rationally. |
