Abstract
PURPOSE:To eliminate a fault caused by static electricity, by providing a photoelectric converting element for inputting a data, alight shielding element for outputting data, and a solar battery, etc., on an IC card, and coupling it to an external device by using a light beam. CONSTITUTION:When an IC card 2 is inserted into a pocket of an external device 3, a current is generated in a solar battery 25 by a light beam from a power source part light source 34, and each element contained in the IC card becomes an operating state. In this state, when an input part light source 31 is flickered, a signal is inputted to a control element 24 through a photoelectric converting element 21, and the data can be inputted to a nonvolatile storage element 22 through the element 24. Also, based on a signal from the element 24, the data of the element 22 is inputted to a light shielding element 23 and a shutter for constituting the element 23 is opened and closed. On the other hand, a light beam outputted from an output part light source 32 irradiates the whole surface of the element 23, and by opening and closing of the shutter for constituting the element 23, a leaked light beam is detected by a photoelectric converting element 33.
