Abstract: An image recording apparatus for a microscope having a still camera function and/or a video photography function is disclosed. Automatic exposure (AE) adjustment is performed at appropriate time intervals in the photographic period so as to obtain sample images of roughly uniform brightness. Also, image data and data of plural photographic conditions are recorded in a single photographic session by setting up an AE adjustment time (Tae) and an exposure time (Texp) so as not to exceed a photographic interval (Tint) that is constant.

Abstract: The cooling device of the present invention includes a casing divided into a first fluid passage and a second fluid passage by a fluid separation plate; a heat exchanger disposed to pass through the fluid separation plate, for receiving heat from high-temperature air flowing in the first fluid passage and for radiating the heat to the outside air flowing in the second fluid passage; an inside fan for blowing the high temperature air in the first fluid passage; an outside fan for blowing the outside air to the second fluid passage; and a thermistor for sensing a temperature of the high temperature air flowing in the first fluid passage. A rotational speed of each of the fans of the inside fan and the outside fan is variably controlled in response to a temperature detected by the thermistor with the controller. In this way, it is possible to cooling an interior of a closed box and to reduce the consumed electric power.
