Abstract: An information-processing unit is provided, which is connected to an external unit through a connection cable, comprising a connector with multiple contact pins, and a recognition means for sensing a specific contact pin of the multiple contact pins in the connector and recognizing the type of connection cable to be accommodated in the connector. A connector is provided, comprising an upper surface member, rear wall and lower surface member with an open portion formed at the front into which a plug is inserted, as well as a plate member in parallel from the rear wall to the lower surface member, and a contact pin on the upper surface of the plate member, in the vicinity of the lower surface member, and a standing wall at the end of the plate member on the upper surface side of the plate member.

Abstract: In an electronic device mounting an electronic circuit module on which electronic components are mounted and having a fan that discharges air from inside the electronic device to an outside of a component when the electronic circuit module operates, the electronic device having an exhaust port provided on a side wall of the component, a duct provided so as to contact the exhaust port on an inside of the component, and a fan portion provided on the duct inside the component. Accordingly, the exhaust from the fan portion passes through the duct and is discharged from the exhaust port, with the airflow generated inside the component able to prevent a rise in temperature inside an electronic circuit module such as a personal computer or television game device due to heat generated from the electronic components mounted on an electronic circuit module.
