    • A shutter mechanism for a camera having a release member, which is arranged to be moved in a predetermined moving direction from an original position by depressing a shutter button, and a delay member. The delay member is movable relative to the release member and in parallel to the predetermined direction. The delay member is biased along them moving direction of the release member and is arranged to actuate the shutter mechanism of the camera when the delay member is located at a predetermined position. Simple, mechanical holding mechanisms temporarily stop both the release member and the delay member at other predetermined positions for a predetermined period before the delay member is released to actuate the shutter mechanism. Utilizing this delay mechanism, the camera can be made smaller and the manufacturing cost can be reduced.
    • 一种用于具有释放构件的相机的快门机构,其被布置成通过按下快门按钮从原始位置沿预定移动方向移动,以及延迟构件。 延迟构件相对于释放构件可移动并且平行于预定方向。 延迟构件沿着其沿着释放构件的移动方向被偏置,并且被布置成当延迟构件位于预定位置时致动照相机的快门机构。 简单的机械保持机构在延迟构件被释放以致动快门机构之前暂时将释放构件和延迟构件在其它预定位置停止预定时间段。 利用该延迟机构,可以使照相机更小,并且可以降低制造成本。

    • A manual focusing mechanism, of an imaging apparatus provided with a lens system that includes a focusing lens group, which changes an image plane position by linearly moving the focusing lens group in an optical axis direction thereof via a manual operation of a focusing operational member includes a click-stop mechanism which holds the focusing operational member at one of a plurality of click-stop positions with respect to a support member. An amount of movement of the image plane position in the optical axis direction per one click-stop position of the focusing operational member via the click-stop mechanism is determined to be within a range of the depth of focus of the lens system of the imaging apparatus. An imaging apparatus having such a manual focusing mechanism is also disclosed.
    • 包括通过手动操作聚焦操作部件,通过使聚焦透镜组在光轴方向线性移动而改变像面位置的具有聚焦透镜组的透镜系统的摄像装置的手动聚焦机构, 点击停止机构,其将聚焦操作构件保持在相对于支撑构件的多个点击停止位置中的一个处。 通过点击停止机构,聚焦操作构件的每个点击停止位置的光轴方向上的图像平面位置的移动量被确定为在成像的透镜系统的焦深的范围内 仪器。 还公开了一种具有这种手动对焦机构的成像装置。
