摘要

An endoscope system having an elongated insertion portion, an endoscope provided with an image guide disposed in the elongated insertion portion and adapted to transmit an optical image, and an ocular portion facing an emergence-end surface of the image guide. A transmission line for transmitting an image signal supplied from an imaging unit having an imaging means and capable of being mounted on the ocular portion is provided on the side of the endoscope, thereby eliminating the need for leading any cable out of the imaging unit.
