ABSTRACT:
An endoscope ocular device comprises a hollow cylindrical housing and a return ring which is rotatably mounted on the housing, and rotated with a photographic camera fixed in place, whereby adjusting an ocular to a prescribed dioptric position, no matter how the ocular was previously disposed. A contact chamber is provided between the return ring and housing. Provided in the return ring is a first electrical contact, one end of which is exposed to the outer periphery of the return ring, and the other end of which projects into the contact chamber. Provided in the contact chamber is a second electrical contact which is removed from the first electrical contact when the photographic camera is taken off, and connected to the first electrical contact when the photographic camera is fixed in place, and is also connected to an electric power source. That end of the first electrical contact which is exposed to the outer periphery of the return ring is accessible and can be cleaned with water quickly and reliably. When the photographic camera is taken off the ocular device, the first electrical contact is disengaged from the second electrical contact. Therefore, the operator who happens to touch the exposed end of the first electrical contact is not subject to an electric shock.
