Abstract
A co-reviewing device has a body having a connecting portion detachably connected to the eyepiece section of an endoscope, and having a main eyepiece section to which a photographing device can be connected. A sub-eyepiece section is connected to the body. A support frame 21 supporting a half prism and a transmitting prism is arranged in the body to be movable between a first position where the half prism is on the optical axis of the beam, which is sent from the endoscope into the body, to divide the beam and guide the divided beams into the main and sub-eyepiece sections, and a second position where the transmitting prism is on the optical axis to guide all of the beam to the main eyepiece section. A changeover mechanism is arranged in the body to engage with the support frame and to be engageable with the photographing device. The changeover mechanism switches the support frame to its second position, in accordance with the operation of connecting the photographing device to the main eyepiece.
