Abstract
A fluorescent diagnosing apparatus includes a normal image television camera which picks up a normal observation image that is transmitted through an ocular portion of an endoscope and a fluorescent image television camera which intensifies and picks up a fluorescent image transmitted through the ocular portion. An optical path switching member which selectively guides light along an optical path extending from the ocular portion to one of the normal image television camera and the fluorescent image television camera is provided together with a light interrupting member which is positioned between the optical path switching member and the fluorescent image television camera when the optical path switching member is in a normal observation status in which the optical path switching member guides the light along the optical path from the ocular portion to the normal television camera. In addition, a support frame which defines at least two stationary planes extending in different directions is provided together with at least one elastic pressing mechanism which elastically presses the switching member against the stationary planes while permitting the switching member to slide along the stationary planes.
