发明名称 Distance measuring device and a camera using the same
摘要 A distance measuring device by use of a light passive method which is used in a lens shutter camera and the like. The device includes a distance measuring module which comprises a separator lens and photoelectric conversion element chips. Wherein the module, the element chips are arranged in horizontal and vertical direction in cross-pattern, and each optical path of a plural luminous flux from the separator lens to the element chips is restricted only by the distance measuring module itself. In accordance with an electric signal of pairs of the object image formed on the element chips, a distance to an object can be detected. Thereby a probability of distances measuring is improved without a restriction for taking in luminous flux widely for distance measuring.
