1. A plate-shaped external storage device for recording and saving data and for use in combination with an external storage device unit main, the plate-shaped external storage device having a periphery composed of a front side, a back side, and longitudinal sides parallel to an inserting direction of the plate-shaped device into the external storage device unit main, the external storage device comprising:

  • a non-volatile semiconductor memory device provided with a plurality of input/output terminals;

    a plurality of external connection terminals connected to the input/output terminals, the plurality of external connection terminals having end surfaces disposed on each of the longitudinal peripheral sides of the plate-shaped external storage device; and

    an insulator coating and sealing the memory device and the external connection terminals unitarily into a molded plate to form a plate-shaped external storage device, wherein the end surfaces of the plurality of external connection terminals are disposed on each of the longitudinal peripheral sides of the plate-shaped external storage device in concavities so as to permit attachment to and detachment from an engaging section of a connection section on the external storage device unit main, wherein the plate-shaped external storage device has a cut-off portion at a corner on the back side, the cut-off portion providing an indicating mark for an indication of an insertion direction, and wherein the plate-shaped external storage device is controlled by a control circuit.
