    摘要： Disclosed is an optical lens which can be produced by injection molding on an industrial scale and which has a high refractive index, a low Abbe's number, a low birefringence index, a high transparency and a high glass transition temperature. The optical lens can be produced by injection molding of a polycarbonate resin (preferably having a reduced viscosity of 0.2 dl/g or higher and a glass transition temperature of 120 to 160° C.), wherein the polycarbonate resin is produced by reacting a diol component comprising 99 to 51 mol % of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene and 1 to 49 mol % of bisphenol A with a carbonate diester. It becomes possible to produce an optical lens preferably having a refractive index of 1.60 to 1.65, an Abbe's number of 30 or smaller, a birefringence index of 300 nm or lower and an all light transmittance of 85.0% or higher.

    摘要： A movable mirror shock-absorbing mechanism of a camera, includes a movable mirror rotatable between a viewfinder light-guiding position and a retracted position, a mirror-advancing shock-absorbing member which comes into contact with, and is pressed and moved by, the movable mirror to absorb shock of the movable mirror when the movable mirror rotates from the retracted position to the viewfinder light-guiding position, and a mirror-retracting shock-absorbing member which comes into contact with, and is pressed and moved by, the movable mirror to absorb shock of the movable mirror when the movable mirror rotates from the viewfinder light-guiding position to the retracted position. The mirror-advancing shock-absorbing member is held in a position so as not to contact with the movable mirror by the mirror-retracting shock-absorbing member when the movable mirror is in the viewfinder light-guiding position.
