  • Mirror installation in an optical device
    Patent number: 5194994
    Abstract: Structure and method for mirror installation in an optical device such as a laser beam scanning device. An installation reference surface and a support surface are formed to be faced to but spaced apart from each other. The mirror is installed between the above two surfaces in such a manner that the reflection surface of the mirror contacts the installation reference surface. An elastic element is inserted and press-fitted between the rear surface of the mirror and the support surface so as to push the mirror against the installation reference surface. Thus, the mirror is stably held between the installation reference surface and the support surface with accurately positioning the reflecting surface of the mirror.
