Abstract
PURPOSE: To reduce the spacing for inserting prism and achieve the miniaturization of the camera by using the small size prism of the specified conditions.
CONSTITUTION: A small-size prism 12 for leading information light is disposed in adjacency to a roof prism 6 which leads the luminous flux from the subject to an eyepiece lens 7. The luminous flux from an information source is then reflected by the reflecting face of the prism 12 and is led to the incident face of the prism 6. And the shape of the prism 12 is so determined that the position where the ray emitted from the information source 11 enters the prism 12 comes closer to the prism 6 along the optical axis direction of the finder than the position where it reflects on the reflecting face of the prism 12. Mirror surface treatment is applied to the reflecting surface of the prism 12.
