Thus, an optical apparatus characterized in that the shape of the photographing aperture is defined. 前記露呈する端縁の近傍に塵埃を吸着するための措置を施したことを特徴とする請求項２に記載の光学装置。  The optical apparatus according to claim 2, wherein a measure for adsorbing dust is provided in the vicinity of the exposed edge. 前記露呈する端縁を覆い隠す位置に固定可能な部材を備えたことを特徴とする請求項２に記載の光学装置。  The optical apparatus according to claim 2, further comprising a member that can be fixed at a position that covers the exposed edge. 前記撮影用開口を通過して前記光透過部材の端面で反射した光束が前記受光素子に入射しないように、前記光透過部材と前記撮像素子との間に遮光部材を設けたことを特徴とする請求項１〜４のいずれかに記載の光学装置。  A light shielding member is provided between the light transmission member and the image sensor so that a light beam that has passed through the photographing aperture and reflected by an end surface of the light transmission member does not enter the light receiving element. The optical device according to claim 1. 光路中に開口および光学部材が配置された光学装置において、
前記開口を通して前記光学部材を見たときに、該光学部材の有効領域に加えて非有効領域の一部が前記開口から露呈可能に構成したことを特徴とする光学装置。In an optical device in which an aperture and an optical member are arranged in an optical path,
An optical device, wherein when viewing the optical member through the opening, a part of the ineffective area in addition to the effective area of the optical member can be exposed from the opening. 撮影レンズを着脱するための開口を有し、装着された撮影レンズを透過した撮影光束が撮影用開口を通過して光透過部材に入射し、該光透過部材の透過光が撮像素子に入射するよう構成したデジタルスチルカメラにおいて、
前記レンズ着脱用開口から前記撮影用開口を通して前記光透過部材を見たときに、撮影用開口の４辺のうち１辺側においては、該光透過部材の端縁の少なくとも一部が前記撮影用開口から露呈するように該撮影用開口の形状を定めたことを特徴とするデジタルスチルカメラ。An aperture for attaching and detaching the photographic lens is provided, and the photographic light beam transmitted through the attached photographic lens passes through the photographic aperture and enters the light transmission member, and the transmitted light of the light transmission member enters the image sensor. In the digital still camera configured as described above,
When the light transmitting member is viewed from the lens attaching / detaching opening through the photographing opening, on one side of the four sides of the photographing opening , at least a part of the edge of the light transmitting member is the photographing member. A digital still camera, wherein the shape of the photographing opening is determined so as to be exposed from the opening.
