Then, the setting contents of the memory card 12 are read by the reading circuit unit 13 and the setting contents are output to the operation switch determination circuit unit 14. The operation switch determination circuit unit 14 sets the operation switch 11c of the foot switch 11 to the focusing unit UP operation switch according to the setting content, and the display circuit unit 15 outputs a display signal q according to the setting content and sets the operation switch 11c. A light is displayed on the display to indicate that the switch is the focus focus UP operation switch. When the operation signal C of the operation switch 11c is input to the operation switch determination circuit unit 14, a focusing unit UP drive command signal is output to the control unit 17, and the control unit 17 causes the focusing unit 20 to move in the UP direction.

Function settings can be made, and each set value at that time can be written and stored in the memory card 12, and as a result, the reproducibility of complicated observation conditions that differ depending on the sample or the like is improved. Further, erroneous operations and the like can be reduced.
