摘要： The focusing detecting device determines whether or not the optical image of an object to be photographed is in a focusing state in which the image is clearly formed on a predetermined image forming surface through a photographing or image forming optical system. The device can be used with a dark optical system.

摘要： A hard endoscope which can be removably fitted with a photographing device in the eyepiece part and by which, for example, a body cavity in which it is inserted can be observed and photographed is disclosed. In the case of taking a photograph with a hard endoscope fitted with a photographing device in the eyepiece part, if the optical axis of the hard endoscope and the optical axis of the photographing device do not coincide with each other and are eccentric from each other, the image obtained in the photographing device will differ from that seen by the endoscope. Therefore, the hard endoscope of this invention is provided in the eyepiece part with an eccentricity controlling means which can center the optical axis of the hard endoscope to coincide with the optical axis of the photographing device.
