Estimating the term…
There is provided an optical apparatus which has excellent assembly performance, can suppress an increase in cost, and attain a decrease in thickness. The optical apparatus includes a board (1) having a photographing optical system and a mechanical system mounted on its surface. A plurality of opening portions (1a, 1b, 1c) are formed in the board (1). The opening portion (1a) is sealed with a sealing member such as a glass member to allow a light beam to pass and prevent dust and the like from entering the storage space for parts between the board (1) and a shield case (49). The photographing optical system mounted on the board (1) includes a stop unit (30) for adjusting the light amount of an object image guided through the opening portion (1a), and prism-like optical members (G1, G2, G3, G4), each consisting of, e.g., a glass or plastic material and having a sculptured surface as a reflecting surface. Light emerging from the optical member (G4) is received by a solid-state image sensing element (2) mounted on the lower surface of the board (1) through the opening portion (1c).
An optical apparatus for forming an object image on a solid-state image sensing element through a photographing optical system, comprising a board on which said photographing optical system and said solid-state image sensing element are mounted, wherein a movable optical member included in said photographing optical system and movable relative to said solid-state image sensing element, and position detection means for detecting a moving position of said movable optical member are mounted on said board.
An optical apparatus for forming an object image on a solid-state image sensing element through a photographing optical system, comprising a board on which said photographing optical system and said solid-state image sensing element are mounted, wherein a movable optical member included in said photographing optical system and movable relative to said solid-state image sensing element, and at least some of constituent members of an actuator for moving said movable optical member in a predetermined direction are mounted on said board.
An optical apparatus for forming an object image on a solid-state image sensing element through a photographing optical system, comprising a board on which said photographing optical system and said solid-state image sensing element are mounted, wherein light amount adjustment means for adjusting a light amount of the object image, and at least some of constituent members of an actuator for driving said light amount adjustment means are mounted on said board.
An optical apparatus for forming an object image on a solid-state image sensing element through a photographing optical system, comprising a board on which said photographing optical system and said solid-state image sensing element are mounted, light amount adjustment means for performing a light amount adjusting operation to adjust a light amount of the object image, and drive means for generating a driving force used by said light amount adjustment means to perform a light amount adjusting operation, wherein said light amount adjustment means and said drive means are arranged on a plane parallel to said board.
An optical apparatus for forming an object image on a solid-state image sensing element through a photographing optical system, comprising a board on which said photographing optical system, said solid-state image sensing element, and light amount adjustment means for performing a light amount adjusting operation to adjust a light amount of the object image are mounted on said board, and a regulation portion for regulating a position of said light amount adjustment means is arranged on said board.
