Claims

[Scope of Claim for Utility Model Registration] (1) The rearmost surface of the photographic lens that constitutes the photographic optical system and has a built-in shutter is located closer to the film surface when it is in a non-photographing state than when it is in a photographic state. A lens barrel configured to be movable in the optical axis direction between the above-mentioned two positions of a shooting enabled state and a non-shooting enabled state; and a detection means for detecting a movement from closed to open; and a detection means for moving the photographing lens in the optical axis direction and detecting that the camera back is opened by the detection means when the photographing lens is in a non-photographing position. driving means for moving the photographing lens in a direction away from the film surface when detecting , and for moving the photographing lens to the non-photographing state position when the detecting means detects that the camera back is closed; A camera characterized by comprising: an operation means for starting the drive means; (2) The camera according to claim 1, wherein the position where the photographing lens should be kept away from the film surface is set at the position where the photographing is possible. (3) When the photographing lens driven by the driving means based on the operation of the operating means is in the photographing enabled position, the photographing lens moves to the non-photographing position even if the camera back is closed. Claim 1 characterized in that it is configured such that the
and a camera according to claim 2.
