An electronic device includes: a body 12 having an electronic component 20, and a cover 14 pivotally attached to the body and having a liquid crystal panel 36. The electronic component of the body is cooled by a fan 22. The liquid crystal panel of the cover is illuminated by a discharge tube 38 and a reflector 40. An air inlet 44 of the cover is arranged being opposed to an air outlet 30 of the body. The discharge tube is cooled by a flow of air produced by the fan for cooling the electronic component of the body. By cooling the discharge tube, the life of the discharge tube is maintained long.

What is claimed is: 1. An electronic device comprising: a first housing having a cooling fan and an electronic component, said cooling fan cooling said electronic component; and a second housing pivotally connected to said first housing, having a display element, a discharge tube for lighting said display element and a reflector, wherein said discharge tube is cooled through said reflector by flowing a flow of air generated by said cooling fan provided in said first housing along said reflector. 2. The electronic device as claimed in claim 1, wherein said first housing includes an air inlet and an air outlet, said cooling fan is arranged between said air inlet and said air outlet, and said second housing includes an air inlet, which is arranged being opposed to said air outlet of said first housing when said second housing is located at a position open to said first housing, and said second housing also includes an air outlet. 3. The electronic device as claimed in claim 2, wherein said air inlet of said second housing is arranged at a position so that a central portion of said discharge tube can be cooled by air sent from said air inlet of said second housing. 4. The electronic device as claimed in claim 2, wherein said air inlet of said second housing is larger than said air outlet of said first housing. 5. The electronic device as claimed in claim 1, wherein said electronic component is CPU, and said cooling fan is arranged so that CPU can be cooled by said cooling fan. 6. The electronic device as claimed in claim 5, wherein CPU is attached with a heat sink, and an air passage to connect said heat sink with said air outlet of said first housing is formed. 7. The electronic device as claimed in claim 1, wherein both end portions of said discharge tube are supported by said reflector through a support member, and a flow of air generated by said cooling fan provided in said first housing cools a portion of said discharge tube arranged inside with respect to said support member. 8. The electronic device as claimed in claim 7, wherein a flow of air generated by said cooling fan provided in said first housing cools a central portion of said discharge tube.
