  The present invention relates to an upright microscope used in the fields of biology, medicine, semiconductors, and the like.

Conventionally, an upright microscope as shown in FIG. 7 is known.
As shown in FIG. 7, this microscope includes a base portion 1001 and a cantilever arm portion 1002 having a substantially reverse letter shape. Above the free end side of the arm part 1002, a lens barrel 1003 for observing the specimen 1012, a binocular part 1004, and an eyepiece lens 1005 are arranged. On the other hand, a revolver 1006 is disposed below the free end side of the arm portion 1002, and a stage 1008 is disposed near the curved portion of the arm portion 1002. The objective lens 1007 is detachably fixed to the revolver 1006, and the capacitor 1010 is attached to the lower part of the stage 1008.

  A stage handle 1009 for moving the stage 1008 in the horizontal direction is disposed below the stage 1008. A focusing handle 1011 for moving the stage 1008 up and down is disposed below the arm unit 1002. By operating the stage handle 1009 and the focusing handle 1011, the focal position can be adjusted to the specimen 1012 placed on the stage 1008.

  A lamp (not shown) is disposed inside the base unit 1001, and light from the lamp is collected by the capacitor 1010 and irradiated on the sample 1012. The image of the specimen 1012 reaches the eyes of the observer through the objective lens 1007, the lens barrel 1003, the binocular unit 1004, and the eyepiece lens 1005. In this way, the specimen can be observed.

  In general, when a specimen is observed for a long time using such a microscope, there is a possibility that the microscope frame is subject to thermal deflection due to lamp heat and a focus shift occurs. As a microscope that can suppress the occurrence of such thermal deflection, a microscope is known in which the rigidity of the frame is increased by providing an auxiliary column that can be attached and detached on the side of the frame (see, for example, Patent Document 1).
