Claims

[Scope of Claim for Utility Model Registration] (1) In a camera that has an automatic focusing mechanism that measures the distance to the subject without passing through the photographic lens,
The infrared light passing through the light emitting lens or the light receiving lens is placed between the infrared light emitting diode and the light emitting lens or between the light receiving element and the light receiving lens, which constitute the automatic focusing mechanism. A camera with a two-way level finder, characterized in that it is provided with a dichroic filter that redirects an optical path in a direction different from that of a light emitting diode or a light receiving element, and a screen having a matte surface is provided on the redirected optical path. . (2) A camera with a two-way level viewfinder according to claim (1) of the utility model registration, characterized in that the screen is curved. (3) having a lens facing the screen;
A camera with a two-way level viewfinder as set forth in claim (1) of the utility model registration, characterized in that it is provided with a magnifier that is detachably attached to the camera body and is attached to the outside of the camera. (4) A camera with a two-way level viewfinder as set forth in claim (1) of the utility model registration, characterized in that the screen having the cloak surface is replaced with a lens.
