A microscope system which can improve the ease of use and the observation environment when a sample is observed using a microscope formed of a stand and a main body which is removable from the stand. A microscope is formed of a main body and a stand, and the main body is removable from the stand. The main body includes an objective lens, an image optical system, a CCD, a compact monitor and a battery, so that the main body, when removed from the stand, can function independently as a microscope. If the main body is mechanically connected to the stand, the main body and the stand are electrically connected via connectors, and an observation image captured by the CCD is supplied from the main body to the stand via the connectors, and is displayed on a monitor.
