Electronic apparatus and method of manufacturing thereof

Abstract

In an electronic apparatus such as a portable computer comprising an electronic apparatus housing having boss portions, projecting portions are formed at locations where boss portions are to be formed. In addition, a boss separate body is provided which has an engaging hole therein and is to be attached to each of the projecting portions to form the boss portions.

1 . An electronic apparatus comprising: 
 a housing formed as one piece with a first boss member; and    a second boss member formed as a separate piece from said first boss member, and mounted on said housing to form a boss portion.    
     
     
         2 . An electronic apparatus comprising: 
 a housing having a projecting portion formed as one piece therewith; and    a boss member to be mounted on said projecting portion to form a boss portion.    
     
     
         3 . An electronic apparatus according to    claim 2   , 
 wherein said second boss member is fixed to said projecting portion by screw engagement.    
     
     
         4 . An electronic apparatus according to    claim 2   , 
 wherein a height of projection of said projecting portions from said housing is within a range of approximately 1.5-2.0 times an external diameter of the projecting portions.    
     
     
         5 . An electronic apparatus according to    claim 1   , wherein said housing is formed of a magnesium alloy, and said boss members are formed of metal.  
     
     
         6 . A method of manufacturing an electronic apparatus having a housing with a boss portion, comprising the steps of: 
 a housing forming step for forming the housing introducing molten metal into a mold device, the housing having a projecting portion at a location where said boss portion is to be formed, and the housing constituting portions other than the boss portion of said housing; and    a boss portion forming step for forming the boss portion by fixedly engaging a boss member, which is to constitute the boss portion, with said projecting portion.
