摘要： A zoom-type viewfinder device which has a multi-sectioned viewfinder cam which rotates in connection with the zooming of a photographic zoom lens. The viewfinder cam has a cam, with at least one cam bevel, which is divided into a first cam component and a second cam component. The first cam component and the second cam component are joined to connect the respective cam bevels to form a cam bevel which wraps more than once around of the cylinder of the viewfinder cam. As the viewfinder cam is manufactured in multiple segments, each segment can be removed from its forming die in the longitudinal direction of the viewfinder cam, thereby providing smooth zooming and a blur free viewfinder image. Also, the inclinations of cam bevels, which are formed on the viewfinder cam, can be made more gradual, which reduces the required driving force. Therefore, a more compact motor can be used, resulting in a more compact camera. Moreover, the power consumption required by the motor is reduced, increasing the life of the camera battery.
摘要翻译： 一种变焦型取景器装置，其具有与摄影变焦镜头的变焦相关联地旋转的多段取景器凸轮。 取景器凸轮具有凸轮，其具有至少一个凸轮斜面，其被分成第一凸轮部件和第二凸轮部件。 第一凸轮部件和第二凸轮部件被连接以连接相应的凸轮斜面，以形成凸轮斜面，凸轮斜面不断地绕取景器凸轮的圆筒包围。 当取景器凸轮制造成多个段时，每个段可以在取景器凸轮的纵向方向上从其成形模移除，从而提供平滑的变焦和无模糊的取景器图像。 此外，形成在取景器凸轮上的凸轮斜面的倾斜度可以变得更加缓慢，从而减小了所需的驱动力。 因此，可以使用更紧凑的电机，导致更紧凑的相机。 此外，电机所需的功耗降低，从而延长了相机电池的使用寿命。

摘要： A camera with a built-in flash unit, provided with a flash emitting portion, includes a red-eye reducing lamp positioned close to the flash emitting portion, and a Fresnel lens positioned in front of the flash emitting portion and the red-eye reducing lamp. Furthermore, the camera includes a protruding portion, which is positioned close to the flash emitting portion and the red-eye reducing lamp and is adapted to be contacted by the finger of the camera-holding hand. Owing to such contact, the photographer is warned as to the improper positioning of his finger, so that the flash emitting portion and the red-eye reducing lamp can be protected from being carelessly covered during the phototaking operation.

摘要： A camera having a lens barrier unit that opens without encountering obstructions in response to the operation of an operating member and without increasing the size of the lens barrel of the camera. The lens barrier unit covers the front surface of a photographic lens in a closed position, and moves clear of the front surface of the photographic lens in an open position. A sliding member, which is a separate member from the operating member, mechanically drives the lens barrier unit to an open position in response to the movement of an operating member by means of the operation for photographic preparation (e.g., when the camera is switched ON), and drives the lens barrier unit to a closed position, by coupling to the movement of the photographic lens unit while moving from the extended position to the retracted position (e.g., when the camera is switched OFF). The camera may include a finder optical system for visually recognizing an image of an object, with the sliding member disposed in the vicinity of a film aperture. The slide member is disposed in a face-to-face position to the finder optical system with the film aperture being interposed therebetween.

摘要： A lens barrel having first and second lens groups and first and second tubes. The first tube has first and second guide grooves to respectively guide the first and second groups in an optical direction. The second tube has first and second cam grooves to respectively guide the first and second lens groups, in conjunction with the first and second guide grooves, for focusing and zooming operations. A first collapsing use groove extends substantially perpendicular to the optical axis from an end of the second guide groove that is closer to an image surface to maintain the second lens group in a stationary position on the optical axis when the first lens group is collapsed toward the second lens group and when the first lens group is extended into a wide state. A second collapsing use groove extends substantially perpendicular to the optical axis from an end of the second cam groove that is closer to the image surface and overlaps the first collapsing use groove to perform the same functions as the first collapsing use groove. The first cam groove is inclined with respect to the optical axis and the second cam groove includes a wide state focusing portion extending substantially parallel to the first cam groove from an end of the second collapsing use groove portion to guide the second lens group uniformly with a movement of the first lens group for focusing of the first and second lens groups in the wide state. The second cam groove above the wide state focusing portion is a stepped groove having alternating zooming portions and focusing portions, wherein the zooming portions are inclined from the optical axis and the focusing portions are substantially perpendicular to the optical axis.
