1. A portable information processing apparatus comprising:a main body having a housing with an interior in which an electronic member for information processing is accommodated, said main body including heat-exchange fins recessed into said housing and exposed to an exterior of said housing; andan external device arranged to be attached to said main body for providing an add-on function;wherein said external device includes a cooling fan arranged to directly cool said heat-exchange fins of said main body when said external device is attached to said main body; andwherein said housing is sealed such that, when said external device is attached to said main body and said cooling fan is directly cooling said heat-exchange fins of said main body, cooling air from said fan does not enter into said interior of said housing. 2. The portable information processing apparatus of claim 1, further comprising a temperature sensor for detecting a temperature of said main body, wherein when said external device is attached to said main body and when a detected temperature exceeds a predetermined temperature, the cooling fan of said external device is activated. 3. The portable information processing apparatus of claim 1, wherein the housing of said main body is made of heat conductive material. 4. The portable information processing apparatus of claim 1, wherein said electronic member for information processing constitutes a heat producing component and is placed inside the main body at a location so as to face the cooling fan of said external device when said external device is attached to said main body. 5. The portable information processing apparatus of claim 1, wherein a heat sink is placed solidly inside the main body at a location so as to face the cooling fan of said external device when said external device is attached to said main body. 6. The portable information processing apparatus of claim 1, wherein said external device has a casing with a cooling-air intake opening and a cooling-air outlet opening formed therein, and when said external device is attached to said main body, said cooling fan is operable to draw cooling air into said casing through said cooling-air intake opening and expel the cooling-air from said casing through said cooling-air outlet opening toward said part of said housing of said main body. 7. The portable information processing apparatus of claim 1, further comprising a heat dissipating member provided between said electronic member for information processing and said housing to conductively thermally couple said electronic member for information processing to said housing. 8. The portable information processing apparatus of claim 2, wherein when said external device is attached to said main body and when a detected temperature is lower than a predetermined temperature, the cooling fan of said external device is deactivated. 9. The portable information processing apparatus of claim 3, wherein the housing of said main body is made from an alloy of magnesium. 10. The portable information processing apparatus of claim 3, wherein said heat-exchange fins are provided to the housing of said main body at a location so as to face the cooling fan of said external device when said external device is attached to said main body. 11. A portable information processing apparatus comprising:a main body having a housing with an interior in which an electronic member for information processing is accommodated, said main body including heat-exchange fins exposed to an exterior of said housing; andan external device arranged to be attached to said main body for providing an add-on function;wherein said external device includes a cooling fan arranged to directly cool said heat-exchange fins of said main body when said external device is attached to said main body;wherein said electronic member for information processing is conductively thermally coupled to said heat-exchange fins; andwherein said housing is sealed such that, w hen said external device is attached to said main body and said cooling fan is directly cooling said heat-exchange fins of said main body, cooling air from said fan does not enter into said interior of said housing. 12. The portable information processing apparatus of claim 11, further comprising a temperature sensor for detecting a temperature of said main body, wherein when said external device is attached to said main body and when a detected temperature exceeds a predetermined temperature, the cooling fan of said external device is activated. 13. The portable information processing apparatus of claim 11, wherein the housing of said main body is made of heat conductive material. 14. The portable information processing apparatus of claim 11, wherein said electronic member for information processing constitutes a heat producing component and is placed inside the main body at a location so as to face the cooling fan of said external device when said external device is attached to said main body. 15. The portable information processing apparatus of claim 11, wherein a heat sink is placed solidly inside the main body at a location so as to face the cooling fan of said external device when said external device is attached to said main body. 16. The portable information processing apparatus of claim 11, wherein said external device has a casing with a cooling-air intake opening and a cooling-air outlet opening formed therein, and when said external device is attached to said main body, said cooling fan is operable to draw cooling air into said casing through said cooling-air intake opening and expel the cooling-air from said casing through said cooling-air outlet opening toward said part of said housing of said main body. 17. The portable information processing apparatus of claim 11, further comprising a heat dissipating member provided between said electronic member for information processing and said housing to conductively thermally couple said electronic member for information processing to said housing. 18. The portable information processing apparatus of claim 12, wherein when said external device is attached to said main body and when a detected temperature is lower than a predetermined temperature, the cooling fan of said external device is deactivated. 19. The portable information processing apparatus of claim 13, wherein the housing of said main body is made from an alloy of magnesium. 20. The portable information processing apparatus of claim 13, wherein said heat-exchange fins are provided to the housing of said main body at a location so as to face the cooling fan of said external device when said external device is attached to said main body.
