A card reader for use with a card formed in a substantially rectangular shape which is conveyed in its short widthwise direction and is processed, comprising: a conveying passage where the card is conveyed; a magnetic head structured to abut with a magnetic stripe formed on one face of the card in parallel with a longitudinal direction of the card for performing at least one of reading of magnetic data recorded on the card and recording of magnetic data on the card; and a head moving mechanism structured to move the magnetic head in a widthwise direction of the conveying passage which is perpendicular to a conveying direction of the card and to move the magnetic head between a head abutting position where the magnetic head is capable of abutting with the magnetic stripe and a head retreated position where the magnetic head is retreated from the conveying passage; characterized in that an IC contact block having a plurality of IC contact springs structured to respectively contact with a plurality of external connection terminals of an IC chip formed on the other face of the card; and a contact block moving mechanism for moving the IC contact block between a spring contact position where the IC contact springs are capable of contacting with the external connection terminals and a spring retreated position where the IC contact springs are retreated from the conveying passage; wherein the conveying passage is formed with an opening part through which the magnetic head is passed when the magnetic head is moved in the widthwise direction of the conveying passage; and wherein the magnetic head is located at the head abutting position and is abutted with the one face of the card at a time when the IC contact springs and the external connection terminals are contacted with each other. a conveying passage where the card is conveyed; a magnetic head structured to abut with a magnetic stripe formed on one face of the card in parallel with a longitudinal direction of the card for performing at least one of reading of magnetic data recorded on the card and recording of magnetic data on the card; and a head moving mechanism structured to move the magnetic head in a widthwise direction of the conveying passage which is perpendicular to a conveying direction of the card and to move the magnetic head between a head abutting position where the magnetic head is capable of abutting with the magnetic stripe and a head retreated position where the magnetic head is retreated from the conveying passage; characterized in that an IC contact block having a plurality of IC contact springs structured to respectively contact with a plurality of external connection terminals of an IC chip formed on the other face of the card; and a contact block moving mechanism for moving the IC contact block between a spring contact position where the IC contact springs are capable of contacting with the external connection terminals and a spring retreated position where the IC contact springs are retreated from the conveying passage; wherein the conveying passage is formed with an opening part through which the magnetic head is passed when the magnetic head is moved in the widthwise direction of the conveying passage; and wherein the magnetic head is located at the head abutting position and is abutted with the one face of the card at a time when the IC contact springs and the external connection terminals are contacted with each other.
