摘要： A photographic camera wherein a filter is moved away from the path of incoming scene light in response to attachment of a source of artificial light. The filter is also movable by way of a manually operated selector which can be locked in a position corresponding to inoperative position of the filter. The selector is automatically unlocked in response to attachment of the light source but continues to hold the filter away from the path of incoming light as long as the light source remains attached. A spring returns the filter into the path of incoming light when the light source is detached so that the camera is then ready for making of exposures in daylight.

摘要翻译： 照相机，其中响应于人造光源的附着而使滤光器远离入射的场景光的路径。 过滤器也可以通过手动操作的选择器移动，该选择器可被锁定在对应于过滤器的不工作位置的位置。 只要光源保持连接，选择器将自动解锁，以响应光源的附着，但是继续将滤光片保持在远离入射光的路径的位置。 当光源分离时，弹簧将滤光片返回到入射光的路径，以便相机随后准备在日光下进行曝光。
