Title:
FOCUSING MECHANISM FOR MICROSCOPE
Document Type and Number:
Japanese Patent JP3872831
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a focusing mechanism for a microscope capable of rapidly and easily performing operation from specimen change to focusing.
SOLUTION: When the sensor board 3b of a moving body 3 is positioned within a specified range and interrupts a photointerruptor 16, '0' output occurs. When a stage largely retreats by the specimen change, etc., the position of the sensor board 3b is off from a range H and the interruption of the photointerruptor is eliminated, '1' output occurs. A pulse converter 14 generates output with smaller ratio than that of the pulse output of a rotary encoder 15 in accordance with the operation of a focusing operation handle when the '0' output is given from the photointerruptor 16, and the converter 14 generates the output with larger ratio than that of the pulse output of the rotary encoder 15 when the '1' output is given from the photointerruptor 16.
