Abstract
A shuttered card-edge type IC card including a base having springs therein and a circuit board, a shutter and a cover provided in succession on at least one surface of the base. The base is formed with guide grooves and guide and spring receiving grooves. The springs are located in the guide and spring receiving grooves to close the shutter. The shutter is provided with pawls to be fitted in the guide grooves, respectively, for guiding the pawls in the guide grooves. The shutter is further provided with spring bias plates to be fitted in the guide and spring receiving grooves, respectively, for guiding the spring bias plates in the guide and spring receiving grooves and biasing the spring bias plates by the springs located therein. The connector comprises ridges located corresponding to the guide grooves of the base of the IC card and to be fitted in the guide grooves. The shutter of this IC card is not easily opened even if any member contacts the card in carrying or using it. Terminals of the IC card are securely in contact with contacts of the connector when the card is inserted into the connector of an electric computer.
