Abstract
To enable a moving object to be movable even when electromotive driving of the moving object is not possible and prevent inconvenience from occurring during medical procedures. A medical observation device includes: an imaging optical system configured to capture an image of a subject; an image sensor configured to photoelectrically convert the image of the subject captured by the imaging optical system; a driving force transmission mechanism configured to have a transmission gear and to transmit a driving force to a moving object; a manual manipulation knob configured to be manipulated to rotate in an axial rotation direction of a fulcrum shaft and to be capable of moving between a first position and a second position in an axial direction of the fulcrum shaft; a switch gear configured to be connected to the manual manipulation knob and to be integrated with the manual manipulation knob and rotate in the axial rotation direction, and to be integrated with the manual manipulation knob and move in the axial direction between a meshing position and a non-meshing position; and a driving motor configured to give a driving force to the moving object. Meshing of the switch gear and the t…
