Abstract: A cooling device is provided for cooling the inside of a main body of an electronic apparatus. The electronic apparatus includes the main body having a movable bottom surface portion and a display unit openable/closable relative to the main body. The cooling device is characterized by including means for transmitting an opening/closing angle of the display unit, and means for driving the movable bottom surface portion in accordance with the opening/closing angle of the display unit transmitted by the transmission means, to enlarge the inner space of the main body, thereby cooling the inside of the main body. Another cooling device is disclosed, which includes means for sucking a first gas, means for discharging the first gas sucked by the sucking means, and means for sucking and discharging a second gas by the action of the first gas discharged by the discharging means.

Abstract: A cooling assisting device which is connected to an information processor for assisting the cooling of the inside of the information processor. The cooling assisting device includes an executing member, typically, a docking connector for executing communication with the information processor; a sucking member, typically, an air inlet for sucking a specific gas; and a supplying member, typically, an air outlet for supplying the gas sucked by the sucking means to the information processor.

Abstract: An electronic device using an operation battery and a memory backup battery includes a device body and a memory backup battery removal preventing mechanism. The device body includes a first accommodating portion for accommodating therein the operation battery and a second accommodating portion for accommodating therein the memory backup battery. The preventing mechanism prevents the memory backup battery accommodated in the second accommodating portion from being removed from the second accommodating portion based on whether or not the operation battery is accommodated in the first accommodating portion.
