PROBLEM TO BE SOLVED: To provide a non-contact signal transmitting device and an X-ray CT apparatus which slow down the temporal change of a signal received by non-contact signal transmission by electromagnetic induction.SOLUTION: The non-contact signal transmitting device includes a transmission signal generation part 51, a transmission coil 52, a reception coil 53, an amplifier element 54, and a capacitive load part 55. The transmission signal generation part 51 generates a transmission signal. Into the transmission coil 52, the transmission signal generated by the transmission signal generation part 51 is input. The reception coil 53 outputs a reception signal according to the transmission signal by electromagnetic induction with the transmission coil 52. The amplifier element 54 is connected to both ends of the reception coil 53 and amplifies the reception signal. The capacitive load part 55 is connected to both ends of the reception coil, includes at least a capacitive load enclosed by the amplifier element 54, and slows down the temporal change of the reception signal.COPYRIGHT: (C)2013,JPO&INPIT【課題】電磁誘導による非接触信号伝送により受信した信号の時間変化を鈍化させることができる非接触信号伝送装置およびX線CT装置を提供する。【解決手段】本発明の一実施形態に係る非接触信号伝送装置は、送信信号生成部51と、送信コイル52と、受信コイル53と、増幅素子54と、容量性負荷部55と、を備える。送信信号生成部51は、送信信号を生成する。送信コイル52は、送信信号生成部51が生成した送信信号を入力される。受信コイル53は、送信コイル52との電磁誘導により送信信号に応じた受信信号を出力する。増幅素子54は、受信コイル53の両端に接続され、受信信号を増幅する。容量性負荷部55は、受信コイルの両端に接続され、増幅素子54が内包する容量性負荷を少なくとも含み、受信信号の時間変化を鈍化させる。【選択図】 図2
