ABSTRACT:
A computer including a body case housing a display, an outer member formed of an impact-resistant material integrally formed on the outside surface of the body case, and an outwardly-projecting cushioning portion formed at each corner of the outside member. Each of the cushioning portions has a first protective portion extending outwardly from the body case, and a second protective portion projecting curvilinearly with respect to the first protective portion and extending onto a surface or a back side of the body case. The cushioning portions are formed of an elastic material. Further, vent holes are formed in the body case which are sealed with a porous film which is permeable to gas but not permeable to water. The vent holes provide an escape path for gas produced by a battery, such as a nickel-hydrogen battery, in the event that the battery explodes within the body case.
