摘要： A photographing apparatus is equipped with a photographing optical system, a film holding member on which the photographing optical system is fixed, a supporting frame which rotatably supports the film holding member around a shaft, an outer supporting frame which rotatably supports the supporting frame around the shaft, a finder optical system which has an optical axis different from that of the photographing optical system and which is mounted on the top surface of the outer supporting frame, an AF distance measuring section for measuring the distance to an object, and a captive cam for driving the film holding member and a captive cam for driving the supporting frames for correcting parallax in accordance with the output of the AF distance measuring section. The captive cams are driven also for correcting the blur of an exposure image.

摘要： A camera which reduces camera shake by adjusting the shutter timing is characterized in that it has a mode for displaying a camera shake amount to allow a photographer to recognize a camera shake. A shutter timing determining section permits shutter release at a timing at which the camera shake amount becomes a predetermined amount or less during a shutter release operation on the basis of the camera shake amount detected by a camera shake detecting section. When a camera shake learning mode is set through an input section, a camera shake amount is converted into a display amount by a display data converting section through a camera shake mode selecting section. This display amount is displayed on a display section in real time while a shutter release button is depressed. The camera shake selecting section inhibits a shutter driving operation of the shutter timing determining section in the camera shake amount display mode, thus also allowing a photographer to learn how to depress the shutter release button without causing a camera shake.
摘要翻译：通过调节快门时间来减少相机抖动的相机的特征在于其具有显示相机抖动量以允许摄影者识别相机抖动的模式。基于由相机抖动检测部检测到的相机抖动量，快门定时确定部分在快门释放操作期间在相机抖动量变为预定量或更小的定时允许快门释放。当通过输入部分设置相机抖动学习模式时，通过相机抖动模式选择部分，通过显示数据转换部分将照相机抖动量转换成显示量。当按下快门释放按钮时，该显示量实时地显示在显示部分上。在相机抖动量显示模式中，相机抖动选择部分禁止快门时机确定部分的快门驱动操作，因此也允许摄影师学习如何按下快门释放按钮而不引起相机抖动。

摘要： A zoom lens barrel is a lens barrel having a plurality of lens groups that change intervals in the direction of an optical axis at the time of a zooming operation and move in one-piece toward the optical axis at the time of a focusing operation thereby fixing the mutual intervals in the direction of the optical axis. Furthermore, the zoom lens barrel drives a second group lens frame toward the optical axis via a cam follower by a three-dimensional cam that rotates around the optical axis at the time of the zooming operation and moves toward the optical axis at the time of the focusing operation to perform zooming or focusing. According to this zoom lens barrel, it becomes possible to make the radial size small and further to easily maintain good optical performance.
摘要翻译：变焦透镜镜筒是具有多个透镜组的透镜镜筒，其在变焦操作时改变光轴方向上的间隔，并且在聚焦操作时以一个朝向光轴的方式移动，从而固定在光轴方向上的相互间隔。此外，变焦透镜镜筒通过凸轮从动件通过在变焦操作时围绕光轴旋转的三维凸轮而朝向光轴驱动第二组透镜框，并在聚焦操作进行缩放或聚焦。根据该变焦镜筒，可以使径向尺寸变小，进一步容易地保持良好的光学性能。
