PROBLEM TO BE SOLVED: To enable an analysis of magnetic record data using an inexpensive small and lightweight manual magnetic card reader instead of an electric magnetic card reader in order to achieve reduction in cost, size and weight of a magnetic card analyzer.SOLUTION: The magnetic card analyzer comprises: a manual magnetic card reader 5 in which a magnetic card 1 in which magnetic data to be an analysis target is recorded and a magnetic card 3 in which a clock signal is recorded are superimposed and manually transported through a card conveyance path 6 on which a pair of magnetic heads 7R, 7L are disposed; and a controller 8 which corrects a magnetic flux inversion interval and a signal amplitude of each pulse waveform of the magnetic data to be an analysis target on the basis of a deviation of the magnetic flux inversion interval of each pulse waveform of the clock signal due to speed unevenness of a card transport speed.SELECTED DRAWING: Figure 2 【課題】磁気カード分析機のコストダウンと小型軽量化を実現するために、電動式磁気カードリーダに代えて、安価で小型軽量な手動式磁気カードリーダを用いて磁気記録データの分析ができるようにする。【解決手段】分析対象となる磁気データが記録された磁気カード１と刻時信号が記録された磁気カード３とを重ね合わせて手動で搬送するカード搬送路６に一対の磁気ヘッド７Ｒ、７Ｌが配設された手動式磁気カードリーダ５と、カード搬送速度の速度ムラに起因する刻時信号の各パルス波形の磁束反転間隔の偏差に基づいて分析対象となる磁気データの各パルス波形の磁束反転間隔及び信号振幅を補正する制御装置８とを備えている。【選択図】図２
