Claims

[Scope of utility model registration request]

It has a plurality of photographing lenses with different focal lengths that are fixedly arranged at predetermined positions within the camera body, and the optical path of the light passing through the plurality of photographing lenses is determined by a combination of a fixed mirror and a movable mirror. In a camera that is capable of taking pictures with taking lenses of various focal lengths by switching in conjunction with the selection of a taking lens, the selection of the plurality of taking lenses to be used for taking pictures can be made by changing the selection of the plurality of taking lenses to be used for taking pictures by switching them in conjunction with the selection of the taking lenses. and a lens cover having a rotation center between the plurality of photographing lenses and rotatably disposed in front of the photographing lens, and an operation section protruding outside the camera body, and a manual an operating member that can be moved within a predetermined range when operated; and an operating member that expands the amount of movement of the operating member and transmits rotational motion to the lens cover, and rotates the lens cover to open the aperture. A photographing lens selection type camera which is operated by accelerating means selectively positioned in front of the plurality of photographing lenses.
