Automatic focusing device
专利汇可以提供Automatic focusing device专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible partly to set an automatic focusing position and a manual focusing position by means of a range finding plate and partly to control a taking lens in the manual focusing position under the condition, in which the focusing operation is effected in a desired photographic range, with the use of a control lever.
CONSTITUTION: When it is intended to accomplish the automatic focusing operation, the index 2a of a range setting plate 2 is adjusted to a symbol A. Then, the arm 70b of a control lever 70 goes out of the moving range of a pin 56 to automatically effect the adjustment of the focal point. When in the manual focusing operation, on the other hand, the index 2a of the plate 2 is adjusted to any of the symbol indicating the manual range finding region. Then, the arm 70b of the control lever 70 occupies a preset position in the moving passage of the pin 56 to regulate the rotation of a let-off lever 54 so that a taking lens L is controlled to a condition where it is focused in the desired photographic range
