An electronic apparatus system comprises a portable computer and an extension device for expanding the function of the portable computer. The extension device includes a base, which has a mounting portion on which the portable computer is removably mounted, an exhaust port opened in the mounting portion of the base and a fan unit housed in the base and arranged to supply cooling air to the exhaust port. The base has a plurality of convex portions formed in a bottom wall that extend upward towards the exhaust port and form a foreign matter capturing region in the base. The base includes an exhaust passage for channeling cooling air from the fan over the bottom surface of the portable computer. The fan unit is inclined so that the axis of rotation is tilted toward the opening in the side wall of the mounting portion at the end of the exhaust passage. A seal is formed around the exhaust passage on the top surface of the mounting portion so that when the portable computer engages the extension device, an air seal is formed to prevent cooling air from exhausting except through the opening in the side wall of the extension device.

A blower is provided for effectively cooling heat generating parts in a casing of a personal computer and so on, with a heat sink apparatus using the blower and an electronic equipment using the heat sink apparatus. The blower comprises a fan and an outer frame. The outer frame of the fan is made of a highly thermally conductive material such as aluminum. A radiation board is fixed to or formed integrally with a lower surface of the outer frame. Heat generated from a heat generating device is conveyed through the radiation board to the outer frame. The blower is provided with radiation fins so that the heat conveyed to the outer frame is transferred to the radiation fins as well.

A personal computer has a casing that includes a bottom wall formed having fitting holes and a rear wall provided with a first expansion connector. An expansion adapter to which the computer is connected includes a carrying surface, on which the casing is detachably mounted, and a first relay connector connectable with the first expansion connector of the casing placed on the carrying surface. Arranged on the carrying surface are guide rails that guide the casing in movement along the directions of connection and disconnection of the connectors. The expansion adapter includes locking members, which are swingable between a locking position in which they project from the carrying surface and an unlocking position in which they are situated below the carrying surface. When the computer is slid along the guide rails on the carrying surface so that the first expansion connector is connected to the first relay connector, the locking members move to the locking position, in which they project from the carrying surface, and engage their corresponding fitting holes of the casing, thereby locking the computer.

A portable electronic apparatus comprises a box-shaped housing. A metal-made frame is contained in the housing. The frame supports a circuit board. A circuit element, generating heat while operating, is mounted on the circuit board. A fan is contained in the housing so as to guide cooling air to the circuit element. The frame has a cooling air passage to guide cooling air thereto by the fan. The cooling air passage has a heat receiving part where heat of the circuit element is transmitted, and the heat receiving part is cooled by cooling air flowing to the cooling air passage.

An electronic system includes an electronic apparatus body and an external expansion unit. The electronic apparatus body has a bottom surface and a rear surface. A first connector is arranged on the rear surface. The external expansion unit has a first surface opposing the bottom surface, and a second surface opposing the rear surface. The external expansion unit has a second connector which is detachably connected to the first connector. The external expansion unit has an engaging device. The engaging device is movable between the first position where the engaging device is separated from the bottom surface and the second position where the engaging device is engaged with the bottom surface to pull the electronic apparatus body toward the second surface. The external expansion unit has an operation mechanism for selectively moving the engaging device to the first and second positions.

An electronic apparatus is provided with a base unit and a display unit. The base unit has an opening formed on the upper surface. The display unit incorporates a display device and supported by the base unit. The display unit is rotatable between a first position where it is tilted down in such a manner as to cover the upper surface of the base unit and a second position where it is raised in such a manner as to expose the upper surface. The display unit includes a projection portion which is inserted into the opening when the display unit is rotated to the first position. A switch for turning the display device on or off is arranged inside the base unit. The switch includes an operation element opposed to the opening of the base unit. When the display unit is rotated to the first position, the operation element is pushed by the projection portion, thereby turning off the display device.

A housing of a computer is provided with a mounting section in which first and second pack-type devices can be set alternatively. The mounting section is defined by a recess that opens continuously in a bottom wall and a side wall of the housing. The first pack-type device includes a first device body and a first cover removably attached to the first device body, and has a thickness substantially equal to the depth of the recess. The first pack-type device is set in the recess in a manner such that the first cover closes an the of the recess and is flush with the bottom wall. The second pack-type device includes a second device body and a second cover removably attached to the second device body, and has a thickness greater than the depth of the recess. The second pack-type device is set in the recess in a manner such that the second cover closes the opening of the recess and project from the bottom.

In a battery-driven computer system, a flip-flop circuit selects one of two switches for switching a power supply to the computer system in accordance with the terminal voltages of batteries detected by detecting circuits. When the first switch is switched on, the first battery coupled to the first switch supplies its power to the computer system. In this case, the second switch is switched off and the power from the second battery coupled to the second switch is not supplied to the computer system. When the terminal voltage of the first battgnal representing the power condition of the batteries.
