摘要： A finder parallax correction lens capable of giving a visual indication, a supplementary lens and a glass protector for the main taking lens are aligned in a planar arrangement and movably built in the camera. When the supplementary lens for photographing subjects at near or close distances is placed in front of the main taking lens with its optical axis in alignment with that of the taking lens, the correction lens is set in position for the finder optical system, visually indicating that it is so positioned, with the glass protector brought to its retracted position. A lock mechanism is further provided which permits the shutter to be tripped only when the lenses and glass protector are set in correct photographing positions respectively and which otherwise locks the shutter against tripping.

摘要： A camera is provided with a socket for receiving a flash unit containing percussion-ignitable flash lamps and spring loaded strikers retained in cocked positions. A sensing system includes a shift member which moves to a first position in the absence of a flash unit, a second position in the presence of a cocked striker and a third position when the cocker is in its uncocked position. A transmission lever is located in the path of the spring loaded shutter opening member when the shift member is in its second position so that upon release of the shutter opening member it drives the shift member to release the striker and ignite a flashlamp. A light detecting member shifts the transmission lever out of the path of the opening member when the ambient light is sufficient for photography. A system provides a warning signal in the absence of a flashlamp or when a cocked striker is not in position.
摘要翻译：相机设置有用于接收闪光单元的插座，其包含冲击可点燃的闪光灯和保持在俯视位置的弹簧加载的撞击器。感测系统包括移位构件，其在没有闪光单元的情况下移动到第一位置，在存在击发的撞击器的情况下移动到第二位置，并且当操作者处于未锁定位置时移动第三位置。当换档构件处于其第二位置时，传动杆位于弹簧加载的挡板打开构件的路径中，使得当挡板打开构件被释放时，传动杆驱动换档构件以释放撞击器并点燃闪光灯。当环境光足以进行拍摄时，光检测部件将传输杆移动到开口部件的路径之外。系统在没有闪光灯的情况下提供警告信号，或者当被撞击的撞针不在位时提供警告信号。
