PURPOSE:To make it possible to perform surely the selection even when a plurality of 'photographing apparatus are mounted by biassing a light bundle to a light path when insertion into the light path of an observational optical system is done and actuating one of the photographing apparatus in accordance with deviation, insertion and removing. CONSTITUTION:An illuminating light from a lamp 11 of an illuminating light source is vertically biassed by means of a reflective mirror 1d and the objective eyes 7 are irradiated therewith. The reflective light from the objective eyes pass through an objective lens 2b of a variable magnification objective microscopic part 2 and a group 2c of variable magnification lens as an observation light and the light bundle is divided by means of a beam splitter 20b and a part of the bundle is biassed vertically upward and it is entered into a TV camera 20a as a photographing light bundle and photographing is performed by means of an electronic steel picture photographing apparatus 20. Among the observed light, the light bundle passing through the beam splitter 20b is biassed by means of reflective prisms 4b and 4c of a binocular microscopic part 4 as an observation light and reaches observational image forming face 5c. A photographing apparatus actuated only by operation of the beam splitter can thereby the selected. |
