LENS-SIDE INFORMATION TRANSFER MECHANISM BY OPTICAL FIBER

PURPOSE:To obtain the same reliability as an electric contact and to facilitate manufacture, by returning light transmitted from a camera side through optical fibers to the camera side according to lens-side information in bit. CONSTITUTION:Optical fibers 14a-20a fixed to the mount 10 of a camera bo...

description	PURPOSE:To obtain the same reliability as an electric contact and to facilitate manufacture, by returning light transmitted from a camera side through optical fibers to the camera side according to lens-side information in bit. CONSTITUTION:Optical fibers 14a-20a fixed to the mount 10 of a camera body side and having light emitting elements on end surfaces on the opposite side of the mount 10 supply steady light I0 to a lens side. The light passed through those optical fibers is returned to the camera body side through optical transmission systems 14c and 16c in a lens for specifying information in bit positions on the basis of the specific value of stop of the lens, and automatic/manual switching information, etc., and lens-side information is transmitted to an arithmetic circuit by optical fibers 14b-20b coupled with photodetecting elements at end parts.
