ABSTRACT:
A compact viewfinder device suitable for use in a camera. The viewfinder device includes an image-forming optical system to form a subject image on an image-forming plane, and a fiber optical plate having a plane of incidence and an exit plane and which transmits the optical image which has entered the plane of incidence to the exit plane. The plane of incidence of the fiber optical plate is positioned on the image-forming plane of the image-forming optical system, and the fiber optical plate transmits the optical image which has entered the plane of incidence so that it is rotated around an exit axis of the exit plane. The fiber optical plate may also enlarge the optical image entering the plane of incidence so that an enlarged image is transmitted to the exit plane. Further, the exit plane of the fiber optical plate may be tilted with respect to the plane of incidence and perpendicular to the exit axis to allow ease of viewing the viewfinder image.
