Electronic device having two slots different in width

Abstract

A portable electronic device having a body and a first slot formed in the body for selectively accommodating a battery and a first recording medium drive having substantially the same width as that of the battery. The first slot has a first width. The portable electronic device further has a second slot formed in the body for selectively accommodating a second recording medium drive having a width larger than that of the first recording medium drive and the battery with an attachment attached to a side surface thereof. The second slot has a second width larger than the first width of the first slot. With this configuration, the two batteries having the same shape can be simultaneously accommodated into the first and second slots, thereby allowing long-term driving of the portable electronic device.

What is claimed is:  
     
         1 . An electronic device comprising: 
 a first accommodating portion for removably accommodating a first component unit having a first width, said first accommodating portion having said first width; and    a second accommodating portion for removably accommodating any one of a second component unit having a second width larger than said first width and said first component unit with an attachment attached to a side surface thereof for adding a width to said first width to obtain said second width.    
     
     
         2 . An attachment adapted to be attached to a component unit for removable use with an electronic device, comprising: 
 an engaging member for engaging said component unit;    said attachment having a width set so that when said attachment is attached to a side surface of said component unit by said engaging member, a total width of said attachment and said component unit is equal to a width of an accommodating portion provided in said electronic device for removably accommodating said component unit.    
     
     
         3 . An attachment according to  claim 2 , further comprising: 
 an elongated portion having a first width; and    a head portion having a second width larger than said first width;    said second width being set so that the sum of said second width and a width of said component unit is equal to a width of said accommodating portion at its opening exposed to the outside of said electronic device.    
     
     
         4 . A component unit for removable use with an electronic device, comprising: 
 an engaging member for engaging an attachment;    said component unit having a width set so that when said attachment is attached to a side surface of said component unit by said engaging member, a total width of said component unit and said attachment is equal to a width of an accommodating portion provided in said electronic device for removably accommodating said component unit.    
     
     
         5 . An electronic device comprising: 
 a body;    a first accommodating portion formed in said body for selectively accommodating a battery and a first recording medium drive having substantially the same width as that of said battery, said first accommodating portion having a first width; and    a second accommodating portion formed in said body for selectively accommodating a second recording medium drive having a width larger than that of said first recording medium drive and said battery with an attachment attached to a side surface thereof, said second accommodating portion having a second width larger than said first width of said first accommodating portion.    
     
     
         6 . An electronic device according to  claim 5 , wherein said first width of said first accommodating portion is defined by a pair of parallel guide ribs formed in said body, and said second width of said second accommodating portion is defined by a pair of parallel guide ribs formed in said body.  
     
     
         7 . An electronic device according to  claim 5 , further comprising: 
 a first lock mechanism for releasably locking said battery or said first recording medium drive accommodated in said first accommodating portion; and    a second lock mechanism for releasably locking said battery with said attachment attached thereto or said second recording medium drive accommodated in said second accommodating portion.    
     
     
         8 . An electronic device according to  claim 5 , wherein said first recording medium drive is selected from the group consisting of a floppy disk drive and a super disk drive.  
     
     
         9 . An electronic device according to claims  5 , wherein said second recording medium drive is selected from the group consisting of a CD-ROM drive and a hard disk drive.  
     
     
         10 . A battery attachment adapted to be attached to a side surface of a battery having a plurality of recesses, comprising: 
 an elongated portion having a first width;    a head portion integral with said elongated portion, said head portion having a second width larger than said first width; and    a plurality of hooks integral with said elongated portion for engaging said recesses of said battery;    wherein said second width is set so that the sum of a width of said battery and said second width is equal to a width of a slot formed in an electronic device.    
     
     
         11 . A battery attachment according to  claim 10 , wherein said battery attachment is formed by resin molding.
