A plurality of sensors detects the movement of a bead(3) and a position of a cipher shaft(2) holding the bead(3) from the magnetic field. A transmitting device(50) analyzes the calculation information from a digital signal and transmits the calculation information after converting a signal detected by the sensors into the digital signal. A USB(Universal Serial Bus) port(60) transmits the analysis information according to the position of the cipher shaft and the movement of the bead(3) to a computer. The transmitting device(50) comprises an analog/digital converter(51), a data analyzer(52), and a USB controller(53).
