FINDER STRUCTURE FOR SINGLE-LENS REFLEX CAMERA

摘要

PROBLEM TO BE SOLVED: To solve the problem that when the opening of a body mount is opened for lens replacement, dust entering a mirror box from the outside of a camera further enters the penta prism side through a gap around a screen body and may adhere to the surface of a finder screen. SOLUTION: The screen body 54 is supported in a rectangular opening 60a in the top of the mirror box 60 between the penta prism 41 and a reflecting mirror while sandwiching the finder screen 52 between a screen pressing member 56 and itself. A flexible sheet 70 formed from a plate-like flexible member is disposed on the side face 60a' of the opening 60a of the mirror box in the form of a tongue such that its one end 70a1 on the penta prism side is fixed to the side face 60a' of the opening 60a of the mirror box with a double-sided tape 70b and its other side 70a2 on the reflecting mirror side is a free end.
