摘要： A camera body and an interchangeable lens removably mounted thereon are equipped with an automatic focusing arrangement. The interchangeable lens includes a signal means for generating a relation signal representing the relationship between the driving directions of a driven section and a focus adjusting section. The camera body includes a focus condition detecting circuit for generating a focusing signal indicating the direction for focusing, a driving section for driving the driven section and change-over means for reversing the relationship, between a direction indicated by the focusing signal and a driving direction of the driving section in response to the relation signal from the signal means.

摘要： An exchangeable lens assembly detachably mountable on a camera body having an automatic focusing device is selectively capable of either automatic focus adjustment by the operation of the automatic focusing device or manual focus adjustment by a manual operation. In two of the embodiments, the change-over between the automatic focus adjustment and the manual focus adjustment is made by operation of a change-over member provided on a stationary barrel separately from a manual focusing ring. A driven shaft coupled with a focus adjusting mechanism is disengaged from a driving shaft of the automatic focusing device in the case of the manual focus adjustment. In the remaining embodiments, a manual focusing ring rotatable and axially shiftable relative to a stationary barrel is axially shifted between an automatic focusing position and a manual focusing position for the change-over. When the ring is shifted to the automatic focusing position, a driven shaft coupled with a focus adjusting mechanism is engaged with a driving shaft of the automatic focusing device and the ring is un-coupled from the focus adjusting mechanism. When the ring is shifted to the manual focusing position, the engagement between the driven and driving shafts is interrupted and the ring is coupled with the focus adjusting mechanism by frictional engagement due to elastic deformation of a resilient member.
摘要翻译： 可拆卸地安装在具有自动聚焦装置的照相机主体上的可交换透镜组件选择性地能够通过自动聚焦装置的操作进行自动聚焦调节或通过手动操作进行手动对焦调节。 在两个实施例中，通过与手动聚焦环分开设置在固定镜筒上的转换构件的操作来进行自动对焦调节和手动对焦调节之间的切换。 在手动对焦调整的情况下，与焦点调节机构联动的从动轴与自动聚焦装置的驱动轴脱离。 在其余实施例中，相对于固定筒可旋转和可轴向移动的手动聚焦环在自动对焦位置和用于切换的手动聚焦位置之间轴向移动。 当环移动到自动聚焦位置时，与焦点调节机构联接的从动轴与自动聚焦装置的驱动轴接合，并且环从聚焦调节机构脱离联接。 当环移动到手动聚焦位置时，被驱动轴和驱动轴之间的接合被中断，并且环由于弹性构件的弹性变形而通过摩擦接合与聚焦调节机构联接。

摘要： An exchangeable lens includes a lens system which forms an image of a target object on which the lens system is focused, a focus adjusting means manually operable for adjusting the focus of the lens system, a direction signal generating means which generates a direction signal representing the relationship between the operational direction of the focus adjusting means of the lens and change of the camera-to-object distance to be focused on by the lens system and a transmitting means which transmits the signal to a camera on which the exchangeable lens is detachably mounted. The camera includes a focus detecting means which receives a light coming from an object and passing through the lens system, a focus condition determining means which is responsive to the output of the focus detecting means to determine the focus condition and the direction of operation of the focus adjusting means to attain an in-focus condition for the focus adjustment and a display means which indicates the focus condition and the direction of focus adjustment. The display means indicates a proper direction of operation of the focus adjusting means towards an in-focus condition, even if the relationship between the operational direction and change of focus differs with the exchangeable lenses.

摘要： A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera can be provided in which the ratio of an object to the photographing frame can be set in a simple structure.
