Abstract: An image sensing apparatus which can increase the image information amount by performing a pixel displacement by rotating a deflector for changing the optical path of image light incident on an image sensing element about two orthogonal axes (axes A and B) using two cams. The two cams are arranged on one side with respect to the axis B, and are driven by a single motor. Cam surfaces for canceling an interference are formed in advance on the two cams.

Abstract: 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.
