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. According to this invention, not only can the setting of the information-processing unit be automatically changed to a setting compatible with the external unit, it is also possible to prevent the destruction of the semiconductor in the connector or the abnormal operation of the information-processing unit, which is caused by static electricity passing through the contact pin.
