    摘要： To provide a fabricating method of an optical communication part in which an optical element is fixed within a hollow holder, including the step of fixing an optical element by holding the optical element in a hollow portion of a holding portion of a metal made holder and calking a portion of the holder; wherein, the step includes calking the holder by heating the holder to a temperature higher than a operating temperature or cooling the holder to a temperature lower than the operating temperature depending on whether or not a thermal expansion coefficient of the holder is larger or smaller than that of the optical element. When the thermal expansion coefficient of the holder is larger than that of the optical element, and a heating temperature in calking is set within the range of 85° C. to 95° C., while when the thermal expansion coefficient of the holder is larger than that of the optical element the cooling temperature of the holder upon the calking is set within the range of −50° C. to −40° C.

    摘要： An autofocus camera has a photographing lens, a shutter normally urged in a shutter opening direction and arranged to be opened and closed after it has once been closed prior to a photographing operation, a mirror movable between a view position which allows light passing through the lens and the shutter to be transmitted to a viewfinder optical system and an exposure position which allows light passing through the photographing lens and the shutter to be transmitted to the surface of a film, and an automatic focus adjustment apparatus for automatically adjusting the position of the lens. The autofocus camera has a motor-drive control circuit arranged to close the shutter prior to a photographing operation, move the mirror from the view position to the exposure position, cause the shutter to be opened and closed for exposure of the film, cause the film to be wound immediately after completion of the operation of the shutter, move the mirror from the exposure position to the view position, cause the shutter to be opened after the winding of the film has temporarily been stopped, and restart the winding of the film.

    摘要翻译： 自动对焦照相机具有拍摄镜头，通常在快门打开方向上被推动的快门，并且被布置成在拍摄操作之前一旦被关闭之后被打开和关闭，镜子可在允许光穿过镜头的视角之间移动 并且要被传送到取景器光学系统的快门和允许通过拍摄镜头和快门的光透射到胶片表面的曝光位置，以及用于自动调节透镜位置的自动对焦调节装置 。 自动对焦摄像机具有电动机驱动控制电路，该电动机控制电路被布置为在拍摄操作之前关闭快门，将反射镜从视点位置移动到曝光位置，导致快门被打开和关闭以使胶片曝光，导致胶卷 在快门操作完成后立即进行卷绕，将反射镜从曝光位置移动到观看位置，使得在胶片的卷绕暂时停止之后使快门打开，并重新开始胶卷的卷绕。
