摘要：
A data transmission device which can read information on an IC card without changing a structure of a conventional floppy disc drive is provided. The IC card includes memory elements for storing information therein. The IC card is accommodated in the data transmission device and the data transmission device is attached to the floppy disc drive so that data stored in the IC card is read via the floppy disc drive. The IC card is electrically connected to the data transmission device. A magnetic head core unit of the data transmission device is magnetically connected to a magnetic head of the floppy disc drive so as to transmit data to the floppy disc drive via the magnetic head. A waveform of data read from the IC card is changed to a waveform which is conformable to a reproduction characteristic of the floppy disc drive.
