Abstract
An endoscope includes in the viewing head of its insertable section into a cavity of a living body an image sensor for generating a video signal which in turn is transmitted to a television display to be visualized thereon as a television picture. The image sensor with a shape such as a plate is located in a plane containing the longitudinal center line of the viewing head. The location permits to keep the shape of the viewing head unchanged. In addition, the image sensor thus located the interior of the viewing head into two spaces, one accommodating therein a forceps channel, and the other accommodating therein an objective lens assembly, resulting in a most efficient arrangement of essential elements for endoscope.
