PROBLEM TO BE SOLVED: To take a picture in exactly the same manner as was observed with an optical system for observation. SOLUTION: When an image is picked up only by means of a film camera, when a condition where a push button A for a photographing selection means is set to an on state, a button D for photographing is made on after positioning is completed and then, a quick return mirror 8 is released from an optical path within a time TA and during it, pulse signals are successively inputted into a thyristor and a flash light source for photographing shooting and electric charge charged in a stroboscopic capacitor for photographing is discharged instantaneously to the flash light source for photographing and the flash light source for photographing is emitted. This light flux travels forward as in observation, and the image of an eyeground is recorded by means of the film camera. |
