    • In a dual lens camera having a relatively long focal length lens and a relatively short focal length lens selectively used for telephoto and wide angle photography, the lens selection is controlled by movement of a movable mirror with respect to a fixed mirror to establish respective optical pahts for the two lenses. Whenever a back cover of the camera is opened for film loading or unloading, the movable mirror is secured to affix its reflective surface in shielding relation with the reflective surface of the fixed mirror. This is done to prevent dust or other foreign particles entering the surfaces, and to render the reflective surfaces inaccessible to touch.
    • 在具有相对长的焦距透镜和选择性地用于长焦和广角摄影的相对较短的焦距透镜的双透镜相机中,通过可移动镜相对于固定镜的移动来控制透镜选择,以建立相应的光学镜 对于两个镜头。 每当照相机的后盖打开以进行胶片装载或卸载时,可移动镜被固定以将其反射表面与固定镜的反射表面保持屏蔽关系。 这是为了防止灰尘或其他外来颗粒进入表面,并使反射表面不能接触。

    • Apparatus having an optical system including two lens groups movable along an optical axis includes a zooming motor and a linkage interconnecting zooming motor and the two lens groups such that axial displacement of one of said lens groups effects axial displacement of the other of said lens groups. The linkage is configured so as to have a zooming zone, wherein axial displacement of one lens group effects substantially faster axial displacement of the other of said lens groups, such that the focal length of the optical system may be changed, and a focusing zone, wherein axial displacement of the one lens group effects substantially slower axial displacement of the other of said lens groups. Accordingly, the optical system can be focused by the zooming motor without requiring a large amount of lens travel.
    • 具有包括沿着光轴可移动的两个透镜组的光学系统的装置包括变焦电动机和连接互连变焦电动机和两个透镜组,使得所述透镜组之一的轴向位移影响所述透镜组中的另一个的轴向位移。 连杆被构造成具有变焦区域,其中一个透镜组的轴向位移实质上更快地使另一个透镜组的轴向位移更快,使得可以改变光学系​​统的焦距,并且聚焦区域, 其中一个透镜组的轴向位移对另一个所述透镜组的轴向位移实质上较慢。 因此,光学系统可以通过变焦电动机聚焦,而不需要大量的透镜行进。

    • A photographic camera capable of taking interspersed full size and panoramic size exposures comprises a rectangular back frame opening for forming a full size exposure on a film in the camera, and respective masking blades supported for pivotal movement to a masking position for masking an upper rectangular portion and a lower rectangular portion of the back frame opening to allow only a panoramic size exposure to be formed on the film and to a non-masking position not masking the upper and lower portions to preclude a panoramic size exposure from being formed on the film. According to the invention, the masking blades have respective extension means at which they are supported for pivotal movement for moving the masking blades in only one direction from their non-masking position to their masking position and to return the masking blades in only one direction, different than the first-mentioned direction, to their non-masking position.
