摘要： A drive mechanism for a zoom lens system consisting of first and second lens groups has a movable lens barrel fixedly holding the first lens and cam structure consisting of a cam member provided on the second lens group and a cam follower member on the movable lens barrel. The movable lens barrel moves forward or rearward to shift the second lens group forward or rearward relative to the first lens group along the optical axis of the zoom lens system via the cam member so as to continuously change the focal length of the zoom lens system. The cam member is mounted on the movable lens barrel to change the curve of the cam surface relative to the cam follower member only in a middle focal length range.

摘要： A camera with a zoom lens system having at least front and rear lens groups each comprising at least one lens, comprises a movable lens barrel holding the front lens group and being axially movable rearwardly and forwardly relative to a camera body and a moving mechanism for causing the axial movement of the movable lens barrel. The moving mechanism comprises a first cam member provided in the movable lens barrel and a rotatable lever coacting with the first cam member for causing the axial movement of the movable lens barrel, the first cam member having first and second straight cam sections for causing the axial movement of the movable lens barrel between front and rear axial positions and beyond the rear positions, respectively, and further comprises a second cam member provided in the camera body and a bell crank lever rotatably mounted on the movable lens barrel and coacting with the second cam member and the second lens group for shifting the rear lens group relative to the front lens group when the movable lens group is moved between the front and rear axial positions so as to change the zoom lens system between the longest and the shortest focal length and for moving the front and rear lens groups conjointly as a unit when the movable lens barrel is moved beyond the rear axial position, thereby collapsing the movable lens barrel at least almost fully within the camera body.

摘要： A pre-winding type photographic camera is provided with a mode changing mechanism for changing its operational mode between a pre-winding mode in which film is drawn out from a film magazine loaded in the camera and is taken up around the spool of the camera prior to photographing, and photographing mode in which the film is rewound into the film magazine by one frame each time the film is exposed. The mode changing mechanism is arranged to set the operational mode to the pre-winding mode by, in response to the opening of the backlid of the camera, bringing a mode changing member to a pre-winding mode position, and at the same time causing a force to be charged for bringing the mode changing member to a photographing mode position, and by retaining the mode changing member in the pre-winding mode position in response to the opening of the backlid of the camera, and is arranged to change the operational mode to the photographing mode by releasing the mode changing member in response to completion of the pre-winding mode operation, thereby permitting the mode changing member to move to the photographing mode position under the charged force. The mode changing mechanism is further provided with a magazine switch which is closed in response either to insertion or removal of the magazine and is kept closed until it is opened in response to the opening of the backlid of the camera. The magazine switch is inserted into the energizing circuit of the driving motor for driving the film in the pre-winding mode operation in series with the driving motor.

摘要： A controller recognizes the requirement for taking a scenic picture when a scenic picture-taking button is operated to indicate that a scene to be photographed is at infinity rather than at the longest focusable distance of an automatic focusing device, and then sets a taking lens system at an infinity focusing lens position, overriding the automatic focusing device. At the same time, when the scene at infinity is darker than a predetermined brightness level, the controller sets a shutter to open for a predetermined night photography exposure time which is greater than the maximum exposure time that could be set by an automatic exposure control device. When taking a night photograph, light emission from a strobe is prevented.
摘要翻译：当操作风景优美的按钮来指示拍摄场景处于无限远而不是自动聚焦装置的最长可调焦距离时，控制器识别拍摄风景照片的要求，然后设置拍摄镜头系统在无限远聚焦透镜位置，覆盖自动聚焦装置。同时，当无限远的场景比预定的亮度水平暗时，控制器将快门打开一预定的夜间摄影曝光时间，该预定夜间摄影曝光时间大于可由自动曝光控制装置设定的最大曝光时间。拍摄夜间照片时，防止闪光灯发出光。

摘要： A variable focal length camera having at least one auxiliary lens system which is inserted into or withdrawn from the optical axis of a main lens system. A lens holder holding the auxiliary lens system is swingably mounted on a shaft extending in the direction of the optical axis, and moves forward and rearward along the shaft for focus adjustment. In order to cancel the component of a force in the direction of the optical axis exerted by a tool by which a focus adjusting device is operated, the shaft is arranged to be motionless in the direction of the optical axis. According to a preferred embodiment, on the intermediate portion of the shaft, there is formed a thread meshing with a base portion of the lens holder so that the position of the lens holder is adjusted through rotation of the shaft, and after this lens position adjustment the base portion is fixed to the shaft.
