A card reader comprising: a card transfer path through which a card passes; a magnetic head for at least one of reading magnetic data recorded in the card, and recording magnetic data into the card; and a facing roller placed so as to face toward the magnetic head, in such a way as to hold the card, passing through the card transfer path, between the magnetic head and the facing roller itself; wherein magnetic data of a plurality of tracks can be recorded in the card; wherein the magnetic head is provided with a plurality of channels (5a, 5b, 5c) for at least one of reading and recording magnetic data of the plurality of tracks individually; wherein the plurality of channels (5a, 5b, 5c) are placed so as to line up in a widthwise direction of the card, the widthwise direction being perpendicular to a passing direction of the card that passes through the card transfer path, as well as a direction of a thickness of the card; and wherein the facing roller is a taper roller in which an outer diameter at one end of the facing roller in the widthwise direction of the card is greater than an outer diameter at the other end of the facing roller in the widthwise direction of the card; characterized in that the magnetic head is biased toward the facing roller, and moreover the magnetic head is able to tilt with respect to a tilting axis arranged parallel to the passing direction of the card; and in a view from the passing direction of the card, the one end of the facing roller in the widthwise direction of the card and the tilting axis of the magnetic head are displaced from each other in the widthwise direction of the card, wherein in a view from the passing direction of the card, the shape of the facing roller is an isosceles trapezoid. a card transfer path through which a card passes; a magnetic head for at least one of reading magnetic data recorded in the card, and recording magnetic data into the card; and a facing roller placed so as to face toward the magnetic head, in such a way as to hold the card, passing through the card transfer path, between the magnetic head and the facing roller itself; wherein magnetic data of a plurality of tracks can be recorded in the card; wherein the magnetic head is provided with a plurality of channels (5a, 5b, 5c) for at least one of reading and recording magnetic data of the plurality of tracks individually; wherein the plurality of channels (5a, 5b, 5c) are placed so as to line up in a widthwise direction of the card, the widthwise direction being perpendicular to a passing direction of the card that passes through the card transfer path, as well as a direction of a thickness of the card; and wherein the facing roller is a taper roller in which an outer diameter at one end of the facing roller in the widthwise direction of the card is greater than an outer diameter at the other end of the facing roller in the widthwise direction of the card; characterized in that the magnetic head is biased toward the facing roller, and moreover the magnetic head is able to tilt with respect to a tilting axis arranged parallel to the passing direction of the card; and in a view from the passing direction of the card, the one end of the facing roller in the widthwise direction of the card and the tilting axis of the magnetic head are displaced from each other in the widthwise direction of the card, wherein in a view from the passing direction of the card, the shape of the facing roller is an isosceles trapezoid.
