Patent number: 7724543Abstract: A communication apparatus which occupies small space and yet can be connected with numerous external cables and which permits a cooling arrangement to be constructed at low cost. An information processing device constituting the communication apparatus has external cable connection ports provided on both top and bottom surfaces thereof, and thus, more external cables can be connected than in the case of connecting the cables to the side surfaces. Also, the external cables connected to the ports are guided along the top and bottom surfaces toward the front of the communication apparatus with their heights restricted by external cable covers and, therefore, do not occupy substantial space above and below the device. Further, since the external cables are connected to the top and bottom surfaces, the front and rear surfaces of the device have spare space, making it possible to construct a ventilation arrangement such as vent holes and fans.Type: GrantFiled: November 20, 2007Date of Patent: May 25, 2010Assignee: Fujitsu LimitedInventors: Fujio Ozawa, Tetsuya Murayama, Junichi Hayama, Hiroyuki Abe, Hisato Sato
