PURPOSE:To easily recognize a position of the microscope by specifying a position in or in the neighborhood of an observation visual field by using a position specifying means while an operation is being performed. CONSTITUTION:When a part to be operated is focused at an arbitrary position where the microscope 5 is moved in a direction 13 of arrow-head by a horizontal moving mechanism, an operating tool 22 is operated first, and it is brought into contact with a part desired to focus by moving the tip of the tool, and a switch 24 is turned on, and an arithmetic instruction is outputted from a switch circuit to a position arithmetic circuit and first and second arithmetic circuits. The position arithmetic circuit receiving the arithmetic instruction calculates the tip position of the operating tool 22 from the angle information of an encoder, and the second arithmetic circuit receives the positional information of the microscope 5, and also, reads out the position information of the 5 stored in a memory circuit, and calculates deviation quantity in the direction of observing optical axis from both position information, and decides the moving direction and moving quantity of the microscope 5 to correct such deviation simultaneously. |
