Abstract
An upright microscope comprises a microscope main body constituted of a base unit and a stand unit extending upright from the rear end of the base unit. An observation optical system comprising an objective lens and an eyepiece lens is provided at the microscope main body. A stage on which a test piece is placed is assembled into an elevator unit which is caused to move up and down by focusing knobs as an integrated part. The test piece is illuminated by a lamp from below the stage. A recessed portion is formed at the base unit and the lamp is disposed at the recessed portion. The lamp is concealed by a lid member that is attached/detached by sliding over the recessed portion. When the lid member is slid and moved off the base unit, the lamp becomes exposed. As a result, the lamp can be replaced easily.
