Claims

[Scope of utility model registration request]

(1) In a display device in the viewfinder of a single-lens reflex camera in which an image of a display device placed above and in front of a pentaprism is introduced into the pentaprism from the lower front surface of the pentaprism, a light emitting member for illuminating the display device. a lighting device that has a lighting device; a lighting window that takes in outside light from substantially in front of the camera to illuminate the display device; and a lighting prism that guides the light from the lighting device and the lighting window to the display device, the lighting prism , an external light entrance surface and an exit surface that form a predetermined acute angle so as to tilt outside light toward the display device, and the internal light from the illumination device is substantially parallel to external light on the inner surface of the external light entrance surface. An in-finder display device arranged to reflect in the same direction and exit from the exit surface.

(2) The arrangement of the outside light incident surface of the daylighting prism and the illumination device and the shape of the daylighting prism are defined in the scope of the utility model registration claim, in which the outside light incident surface of the daylighting prism is defined to substantially totally reflect internal light. The finder display device described in (1).

(3) The viewfinder display device according to claim (1), wherein the outside light incident surface of the lighting prism is a semi-transparent mirror surface.

(4) The viewfinder display device according to claim (1), wherein the exit surface of the lighting prism is a diffusing surface.
