Abstract: A touch screen (60) disposed on a display surface of a display means (58) is used as an inputting means so that a variety of actions of a microscope can be controlled with sufficient ease and precision. A variety of actions are controlled based on an operator's various finger gestures used on the touch screen disposed on the display surface of the display means, for example, making contact by a finger (tap), making two consecutive contacts by a finger (double-tap), making contact by a finger, and moving the finger without releasing it (drag), making contact by a finger and maintaining the contact for a predetermined time or longer (touch-and-hold), making simultaneous contact by two fingers, and increasing spacing between the fingers (pinch-out) or decreasing the spacing (pinch-in), and making simultaneous contact by two fingers, and moving the fingers in parallel (double-drag).
