ABSTRACT:
An endoscope apparatus includes an endoscope and a drive device connected to the endoscope and having a light source. In the distal-end surface of the insertion section of the endoscope, an observation window and an illumination window are provided. A solid-state image sensor is arranged in the distal-end portion of the insertion section to face the observation window. The sensor receives an optical image passing through the observation window, converts the image into electrical signals and transfers the signals in both vertical and horizontal directions. The sensor is so arranged that the vertical transferring direction defines an angle of about 50.degree. to 90.degree. with a line extending between the centers of the observation and illumination windows.
