Patent ID: 7646534

Claim:
A box-type motor-operated microscope comprising: a motor-operated microscope section having at least: a transmitting illumination optical system; an electric stage for placing a specimen vessel and moving a desired part in the specimen vessel to an observation position; and an image forming optical system provided with an objective lens and an image forming lens; and a housing incorporating the motor-operated microscope section, wherein the housing includes a fixed housing and a moving housing and is constructed so that the moving housing is movable parallel to an oblique direction with respect to the fixed housing while holding optical elements arranged above the electric stage, the moving housing is moved parallel to an oblique upward direction by a preset amount and thereby the specimen vessel placed on the electric stage is made replaceable, and the moving housing is moved parallel to an oblique downward direction to abut on the fixed housing and thereby the motor-operated microscope section is sealed and light-blocked in cooperation with the fixed housing and an optical axis of the transmitting illumination optical system is practically aligned with an optical axis of the image forming optical system.
