DIRECT IMAGE TRANSMISSION DEVICE

PURPOSE:To increase the distance for transmitting an image and to reduce a cost by transmitting the image projected on the end face of the image guide on an object side to the end face of the image guide on the eyepiece side by means of an optical lens system and forming the image. CONSTITUTION:The image on an object 18 to be observed is formed by a lens system 19 in an objective part on the end face 11b of an image guide 11 on the objective part side, and the image thereof is transmitted in the guide 11 and is then projected onto the end face 11a. The image thereof is transmitted by an optical lens system 13 which consists of a collimation lens system 15 and a projection lens system 17 and can adjust freely the space between these lens systems. The image is thereby formed on the forward end face 12a of an image guide 12 on the eyepiece part side. The image formed thereon is transmitted in the guide 12 and is projected onto a rear end face 12b, so that the magnified image is observed by a lens system 20 in the eyepiece part. The distance for transmitting the image is thus increased and the cost is reduced.
