Abstract: The disclosed technology is directed to an endoscopic image capturing device. The image capturing device comprises a first objective lens frame a first lens compartment housing therein first optical members of a first objective optical system and a second lens compartment housing therein second optical members of a second objective optical system that is positioned contiguously with the first objective optical system. A second objective lens frame is disposed for sliding movement with respect to the first objective lens frame in optical axis directions. An image capturing frame is disposed for sliding movement with respect to the second objective lens frame in the optical axis directions and housing therein an image capturing device that has an image capturing surface onto which first and second optical images that has passed through the first and second objective optical systems are focused. A positioning member is disposed in the objective optical system hole.
