20090185286 | Lens barrel and image pickup apparatus - An addendum of a gear portion and a tip end of a first cam follower are located on similar-diameter cylindrical planes centering at a center axis of a cam ring. A gear housing recess is provided in an inner peripheral surface of a fixed ring. A bottom surface of a first-cam-ring-movement cam groove engaging with the first cam follower, and a bottom surface of the recess are located on similar-diameter cylindrical planes centering at a center axis of the fixed ring. A release portion is provided at the inner peripheral surface of the fixed ring to provide communication between a protruding position cam groove portion of the first-cam-ring-movement cam groove and the recess. At the protruding position of the cam ring, a portion of the gear portion near the first cam follower passes through the release portion and is located inside the protruding position cam groove portion. | 2009-07-23 |
20090185287 | Line Head and an Image Forming Apparatus - A line head includes: a first lens formed from a resin and on a glass substrate; and a light emitting element substrate that has light emitting elements arranged in a first direction, wherein a cross section of the first lens taken in the first direction and including an optical axis of the first lens has a configuration wherein a curvature of the first lens at the optical axis has a smaller absolute value than a curvature of an outer peripheral portion of the first lens. | 2009-07-23 |
20090185288 | IMAGING LENS - An imaging lens is provided and includes: in order from an object side of the imaging lens, a first lens having a convex surface on the object side and having a positive power; a second lens having a concave surface on the object side and having a negative power; a third lens having a positive power; and a fourth lens having a convex surface on the object side near a paraxial axis and having a meniscus shape. The imaging lens satisfies conditional expressions as specified. | 2009-07-23 |
20090185289 | Pickup lens - A pickup lens is provided with various aberrations corrected satisfactorily, with a short optical length, and with a sufficient back focus secured. The configuration comprises an aperture diaphragm S | 2009-07-23 |
